[substrate]

Below, the detailed construction of the substrate 11A that the present embodiment relates to is described.

At this, substrate 11A, has between lamp circuit 14 and LED element 12, the first area 15 that the sectional area of the second area 16 that sectional area ratio is different from first area 15 is little.That is, the substrate 11A that the present embodiment relates to, is formed with the region that sectional area is narrow between lamp circuit 14 and LED element 12.

Fig. 7 A is the plane of the example that the substrate 11A that embodiment 2 of the present utility model relates to is shown.Further, Fig. 7 B is the sectional view of the example that the substrate 11A that embodiment 2 of the present utility model relates to is shown.Specifically, Fig. 7 B illustrates, the section A-A of Fig. 7 A and section B-B.

In the present embodiment, substrate 11A, between lamp circuit 14 and LED element 12, has the region that sectional area is little.That is, substrate 11A, has between lamp circuit 14 and LED element 12, the first area 15 that the sectional area of the second area 16 that sectional area ratio is different from first area 15 is little.

In other words, substrate 11A, between lamp circuit 14 and LED element 12, has the cross section as second cross-section parallel in the cross section with the part as substrate 11A and first cross section less than the sectional area in this second cross section.In the case, the first cross section is, the cross section of the substrate 11A in first area 15, and the second cross section is, the cross section of the substrate 11A in second area 16.

Specifically, as Fig. 7 A illustrates, in first area 15, the short direction along substrate 11A is formed with slit.In the example shown in Fig. 7 A, slit, from the side on the long limit of substrate 11A, namely from a direction formation.In other words, slit, from the long limit of substrate 11A, is namely formed as from the side that the short direction with substrate 11A is orthogonal, along short direction incised notch substrate 11A.

Substrate 11A, such as, length is 1150 to 1200mm (length direction), and width is 5 to 25mm (short direction), and thickness is 0.3 to 2.0mm.And in the longitudinal direction, substrate 11A is longer than framework 20.

On the surface of substrate 11A, the length direction of substrate 11A is arranged lamp circuit 14 and multiple LED element 12.Now, such as, lamp circuit 14 and apart from being spaced apart between the nearest LED element 12 of lamp circuit 14,5 to 30mm.

First area 15 is, the region between lamp circuit 14 and LED element 12.Such as, first area 15 is, comprises the region of lamp circuit 14 and the mid point apart from the nearest LED element 12 of lamp circuit 14.That is, be formed on the slit of first area 15, be formed to comprise lamp circuit 14 and the mid point apart from the nearest LED element 12 of lamp circuit 14.

Now, slit, rectangular shape, the width (length direction of substrate 11A) of slit is 0.5 to 5mm.Further, the length (the short direction of substrate 11A) of slit is 5 to 20mm.And, also by the length of slit, 10 to 90% of the width of substrate 11A can be set to.

And, the metal line that lamp circuit 14 is electrically connected with LED element 12 is formed, avoids slit.Or, also can replace metal line and lead-in wire etc. is set.

And first area 15 is also passable, be included in the region covered by power supply lamp holder 30.Specifically, lamp circuit 14 and slit also can be configured and be formed as, and are covered by power supply lamp holder 30, thus when overlooking, being hidden and can not watch by power supply lamp holder 30.

Second area 16 is, the region different from first area 15.Second area 16 is, does not comprise the region for the sectional area of substrate 11A being become the structure less than other sectional area.For cross section being become the structure less than other cross section be, such as, slit.

Such as, second area 16 is, as Fig. 7 A illustrates, comprises the region at least partially of LED element 12.Or second area 16 also can be, comprise the region at least partially of lamp circuit 14.Further, second area 16 also can be, can't help power supply lamp holder 30 cover region, such as, the region between adjacent LED element 12.

At this, as mentioned above, the sectional area of first area 15 is less than the sectional area of second area 16.Specifically, the sectional area in first cross section (A-A cross section) of first area 15 is less than the sectional area in second cross section (B-B cross section) of second area 16.Now, the first cross section is, by being formed on the cross section of the slit of first area 15.Further, second area 16 is, does not comprise the region of slit, and the second cross section is, not by the cross section of slit.

First cross section of first area 15 now and the second cross section of second area 16 be, cross section parallel to each other.Such as, the first cross section of first area 15 and the second cross section of second area 16 be, the cross section orthogonal with the direction that lamp circuit 14 and LED element 12 arrange.

In the present embodiment, lamp circuit 14 and LED element 12, arrange at the length direction of substrate 11A, therefore, the first cross section of first area 15 and the second cross section of second area 16 be, the cross section orthogonal with the length direction of substrate 11A, that is, the cross section in the short direction of substrate 11A is comprised.Such as, as Fig. 7 B illustrates, the sectional area (A-A cross section) of the first area 15 in the short direction of substrate 11A is less than the sectional area (B-B cross section) of the second area 16 in the short direction of substrate 11A.

And as Fig. 7 A illustrates, when second area 16 is the regions comprising LED element 12, the second cross section of second area 16 is, the cross section orthogonal with the length direction of substrate 11A and by the cross section of LED element 12.Equally, when second area 16 is the regions comprising lamp circuit 14, the cross section of second area 16 also can be, the cross section orthogonal with the length direction of substrate 11A and by the cross section of lamp circuit 14.Further, the second cross section of second area 16 also can be, can't help region, orthogonal with the length direction of the substrate 11A cross section of substrate 11A that power supply lamp holder 30 covers.Such as, the second cross section of second area 16 also can be, by the cross section between adjacent LED element 12.

[effect]

So, the sectional area of the first area 15 between lamp circuit 14 and LED element 12 is diminished, thus the heat that can occur in inhibition point circuit for lamp 14 is communicated to LED element 12.Therefore, LED element 12, is difficult to the impact being subject to the heat occurred in lamp circuit 14, therefore, it is possible to suppress the reduction of the luminous efficiency of LED element 12.

And, if only consider the impact of the heat transfer from lamp circuit 14, then can consider following situation, that is, prepare two different substrates, at side's collocation point circuit for lamp 14, configure LED element 12 the opposing party, thus suppress the heat transfer between substrate.But in the case, parts number of packages increases, and needs the splicing ear etc. for connecting two substrates, manufacturing cost and manufacturing process is caused to increase.

To this, according to the straight tube LED 1A that the present embodiment relates to, collocation point circuit for lamp 14 and LED element 12 on a substrate 11A, therefore, can not cause the increase etc. of parts number of packages, also can suppress the increase of manufacturing cost and manufacturing process.

Further, the LED module 10A related at the present embodiment is, accepting the mode of alternating current from outside (ligthing paraphernalia), being diminished by the sectional area between lamp circuit 14 and LED element 12 is, especially effectively.

When accepting the mode of alternating current, lamp circuit 14 is, comprises the structure of power circuit (AC-DC change-over circuit).Now, the heat that lamp circuit 14 occurs is higher than the situation not comprising power circuit.Therefore, as the substrate 11A that the present embodiment relates to, by being diminished by the sectional area of the first area 15 between lamp circuit 14 and LED element 12, the inhibition of the reduction of the luminous efficiency of LED element 12 more effectively occurs.

As mentioned above, the illumination light source that the present embodiment relates to, possesses: the framework of elongate; And the substrate of elongate, be configured in framework, and have light-emitting component and for making the lamp circuit of this light-emitting component luminescence, substrate in surface configuration, have between lamp circuit and light-emitting component, the first area that the sectional area of the second area that sectional area ratio is different from first area is little.

Accordingly, by being diminished by the sectional area of the first area between lamp circuit and light-emitting component, the heat that can occur in inhibition point circuit for lamp is communicated to light-emitting component.Therefore, it is possible to suppress according to not resulting from the impact of heat of light-emitting component, the luminous efficiency of light-emitting component reduces.Therefore, according to the illumination light source that the present embodiment relates to, the reduction of the luminous efficiency of light-emitting component can be suppressed.

Further, also can be, light-emitting component and lamp circuit, be arranged and be configured on the length direction of substrate, in the first region, the short direction along substrate forms slit.Now, slit is also passable, is formed from the side on the long limit of substrate.

Accordingly, the so easy structure of slit is set according to the first area at substrate, the sectional area of first area can be diminished, the heat transfer from lamp circuit can be suppressed, the reduction of the luminous efficiency of light-emitting component can be suppressed.

(variation of embodiment 2)

Then, the variation of embodiment 2 of the present utility model is described.In example 2, describe the example being formed with the slit from a direction in the short direction of first area 15, but, also can form slit from twocouese.

Fig. 8 A is the plane of the example that the substrate 11A1 that the variation of embodiment 2 of the present utility model relates to is shown.Further, Fig. 8 B is the sectional view of the example that the substrate 11A1 that the variation of embodiment 2 of the present utility model relates to is shown.Specifically, Fig. 8 B illustrates, the cross section C-C of Fig. 8 A and cross section D-D.

As Fig. 8 A illustrates, in the first area 15a of substrate 11A1, be formed with the slit from twocouese in the short direction of substrate 11A1.That is, slit, is formed from the both sides on the long limit of substrate 11A1.In other words, slit, is formed as from two sides orthogonal with the short direction of substrate 11A1 separately, namely separately from two long limits of substrate 11A1, along short direction incised notch substrate 11A1.

Now, the width (length direction of substrate 11A1) of slit is, 0.5 to 5mm.Further, the length (the short direction of substrate 11A1) of a slit is, 1 to 20mm.And, also the length of a slit can be set to, 10 to 40% of the width of substrate 11A1.Further, two slits also can be, mutually different shape.

Accordingly, as Fig. 8 B illustrates, the sectional area in first cross section (C-C cross section) of the first area 15a in the short direction of substrate 11A1 is less than the sectional area in second cross section (D-D cross section) of the second area 16 in the short direction of substrate 11A1.Now, the first cross section is, by being formed on the cross section of the slit of first area 15a.Further, second area 16 is, does not comprise the region of slit, and the second cross section is, not by the cross section of slit.

As mentioned above, slit is also passable, is formed from the both sides on the long limit of substrate.Even if when the slit that twocouese is formed, also similarly to Example 2, according to the first area at substrate, the so easy structure of slit is set, the sectional area of the first area between lamp circuit and light-emitting component can be diminished, the heat transfer from lamp circuit can be suppressed, the reduction of the luminous efficiency of light-emitting component can be suppressed.

Further, slit also can be, is formed on the through hole of the rectangle of substrate.

Fig. 9 A is the plane of the example that the substrate 11A2 that other variation of embodiment 2 of the present utility model relates to is shown.Further, Fig. 9 B is the sectional view of the example that the substrate 11A2 that other variation of embodiment 2 of the present utility model relates to is shown.Specifically, Fig. 9 B illustrates, the cross section E-E of Fig. 9 A and cross section F-F.

Two datum levels 452 are, such as, and the plane orthogonal and parallel to each other with cap body 410 opening surface.Specifically, two datum levels 452 are, the face orthogonal with the interarea of substrate 11B.That is, two datum levels 452 are set to, from short direction chucking substrate 11B.

And substrate 11B is also passable, contact with one or both of two datum levels 452.Such as, also gap can be there is not between substrate 11B and two datum level 452.

Distance between two datum levels 452 is, more than the width of the end of the opposing party of the length direction of the substrate 11B in the direction of two datum level 452 arrangements.Specifically, also the distance between two datum levels 452 can be set to, equal with the width of substrate 11B, or, longer than the width of substrate 11B.Such as, the difference of the distance between two datum levels 452 and the width of substrate 11B, the i.e. width in the gap of substrate 11B and datum level 452 be, 0 to 5mm.

At this, the end face of the opposing party of substrate 11B, does not contact with bottom surface 451.In other words, between the end face and bottom surface 451 of the opposing party of substrate 11B, there is gap.Accordingly, even if when thermal expansion occurs substrate 11B, substrate 11B can hide into gap, therefore, also can suppress the possibility that the breakage of substrate 11B etc. occurs.

Inwall 470, along the medial surface of cap body 410, is arranged on the inside of cap body 410.Framework 20, is inserted between the medial surface of cap body 410 and the lateral surface of inwall 470, such as, is bonded by adhesive etc. with cap body 410.

One end of lead-in wire 60, is connected with for electrical prongs 320 by through hole 321.Specifically, as Figure 20 and Figure 22 illustrates, one end of lead-in wire 60, the face of among the face be formed with confession electrical prongs 320, to be positioned at cap body 310 centerline side, is welded by solder 322.

The other end of lead-in wire 60, is connected with the tie point on the surface of substrate 11B, specifically, is connected with metal electrode.More particularly, the other end of lead-in wire 60, the metal electrode with near the through hole 140 being arranged on substrate 11B, is welded by solder 131.

Lead-in wire 60 is arranged to, from for electrical prongs 320 successively through the first interarea (surface) side of substrate 11B, the second interarea (back side) side and through hole 140, reach tie point (metal electrode).Specifically, lead-in wire 60 is arranged to, and from passing the first interarea side of substrate 11B, interarea side, wiring space 160, second and through hole 140 successively for electrical prongs 320, reaches tie point.

More particularly, as Figure 22 illustrates, lead-in wire 60, the face of among the face be formed for electrical prongs 320, to be positioned at cap body 310 centerline side, one end is soldered.Lead-in wire 60, after through hole 321, through the inner surface of cap body 310 and inwall 370.And then lead-in wire 60, through the space of the first interarea (surface) side of substrate 11B, specifically, as Figure 20 illustrates, through housing department 390 and substrate 11B.

Then, lead-in wire 60, as Figure 21 illustrates, through wiring space 160.Wiring space 160 is, the space formed by the recess 150 of substrate 11B and the recess 353 of cap body 310.Now, lead-in wire 60, can extend only through the space formed by recess 150, or, also can extend only through the space formed by recess 353.

And then lead-in wire 60, as Figure 20 and Figure 22 illustrates, through the space of the second interarea (back side) side of substrate 11B, specifically, through substrate 11B and the inner surface of cap body 310.Then, lead-in wire 60, through through hole 140, thus again through the space of the first interarea side of substrate 11B.And the other end of lead-in wire 60, is connected with tie point.Specifically, the other end of lead-in wire 60, is welded with tie point by solder 131.

Figure 23 A to Figure 23 C is the sectional view of an example of the connection operation that the lead-in wire 60 that embodiment 4 of the present utility model relates to is shown.And Figure 23 A to Figure 23 C, only illustrates confession electrical prongs 320 periphery in the E1-E1 cross section (XY cross section) of Figure 22.

As Figure 23 A illustrates, lead-in wire 60, inserts from the opening surface of cap body 310 to guide surface 360.And as Figure 23 B illustrates, one end of lead-in wire 60, contacts with guide surface 360, bend to the through hole 321 for electrical prongs 320.Filled in same as before by lead-in wire 60, accordingly, as Figure 23 C illustrates, one end of lead-in wire 60, through through hole 321, is welded by solder 322.

As mentioned above, lead-in wire 60 contacts with guide surface 360, and accordingly, the direction of insertion of lead-in wire 60, bends to the direction towards the through hole 321 for electrical prongs 320.Specifically, lead-in wire 60, after contacting, bends along guide surface 360 with guide surface 360.That is, lead-in wire 60, is in progress along the direction parallel with guide surface 360.

Such as, as Figure 23 A to Figure 23 C illustrates, when guide surface 360 is parallel with the through direction of through hole 321, lead-in wire 60, after contact with guide surface 360 to bend, the through direction along through hole 321 is in progress.Therefore, when guide surface 360 is the faces along the direction towards through hole 321, lead-in wire 60 can be made to pass through through hole 321.Now, when the end of guide surface 360 is positioned at the extended area to the through direction to through hole 321, lead-in wire 60 more can be made to pass through through hole 321.

Figure 24 is the sectional view of an example of the position that the guide surface 360 that embodiment 4 of the present utility model relates to is shown.

As mentioned above, guide surface 360 is, from the face extended on the direction of through hole 321 of the inner surface of cap body 310.In the present embodiment, guide surface 360 is, the plane parallel with the opening surface of cap body 310.

End 361 is, the end of guide surface 360, and is the end close with through hole 321.End 361, is positioned at the extended area in the through direction to through hole 321.Such as, from the distance d of opening surface to end 361 of cap body 310, meet following (formula 3).

(formula 3) d ₁< d≤d ₂

At this, d ₁be, from the opening surface of cap body 310, distance to the place nearest with opening surface among the point in the face that through hole 321 is formed.D ₂be, from the opening surface of cap body 310, among the point in the face that through hole 321 is formed with opening surface place farthest distance.And, for d, more close to d ₂better, preferably, with d ₂equal.

And, the guide surface 360 that the present embodiment relates to, parallel with the opening surface of cap body 310.Therefore, from the distance of opening surface to guide surface 360 of cap body 310, equal with the distance d of opening surface to end 361 from cap body 310.That is, guide surface 360, to meet the mode of (formula 3), is arranged on cap body 310.

So, in the straight tube LED 1B that the present embodiment relates to, there is the guide surface 360 for guiding one end of lead-in wire 60 to the through hole 321 for electrical prongs 320.Therefore, lead-in wire 60, is directed to through hole 321 smoothly, therefore, lead-in wire 60 easily can be made by through hole 321.Therefore, it is possible to improve the reliability of lead-in wire 60 and the connection for electrical prongs 320.

[the first effect]

In the straight tube LED 1B that the present embodiment relates to, for electrical prongs 320 and tie point, be all positioned at the first interarea (surface) side of substrate 11B, they are connected by two lead-in wires 60.Now, arrange through hole 140 at substrate 11B, lead-in wire 60 is arranged to, and passes the first interarea side of substrate 11B, the second interarea side and through hole 140 successively.That is, lead-in wire 60 is arranged to, and walks around substrate 11B.

The lead-in wire 60 be connected with tie point, through through hole 140, accordingly, its routing path is limited.That is, take tie point as the movable range of the lead-in wire 60 of fulcrum, compared with situation about directly will connect for electrical prongs 320 and tie point, the situation through through hole 140 is narrower.Therefore, the load (tension force) being applied to the other end (with the coupling part of tie point) of lead-in wire 60 dies down, accordingly, and the possibility that the broken string that can reduce lead-in wire 60 occurs.

Further, as mentioned above, being positioned at the first interarea side of substrate 11B for electrical prongs 320 and tie point, therefore, in order to make lead-in wire 60 by through hole 140, needing to guide lead-in wire 60 to the second interarea side.Therefore, lead-in wire 60 is arranged to, from the first interarea side through the second interarea side.Specifically, lead-in wire 60 is arranged to, through outside (such as, wiring space 160) and the second interarea side of the first interarea side, side.

So, the routing path of lead-in wire 60, is more limited.Therefore, it is possible to more reduce the load (tension force) being applied to the end of lead-in wire 60, the possibility that the broken string that more can reduce lead-in wire 60 occurs.

As mentioned above, the illumination light source that the present embodiment relates to is, possesses the illumination light source of light-emitting component, possesses: dull and stereotyped, has the first interarea respect to one another and the second interarea and is provided with the first through hole; Be positioned at the attaching parts of the first interarea side; And lead-in wire, one end of this lead-in wire is connected with attaching parts, and the other end of this lead-in wire is connected with the tie point of the first interarea, and for supplying electric power to light-emitting component, lead-in wire is arranged to, and reaches described point successively from attaching parts through the first interarea side, the second interarea side and the first through hole.

Accordingly, lead-in wire is arranged to, through the first interarea side of substrate, the second interarea side and the first through hole, thus the routing path of restriction lead-in wire, therefore, it is possible to reduce the load (tension force) being applied to the end of lead-in wire.Particularly, lead-in wire, is connected with tie point through the first through hole, therefore, is that the movable range of the lead-in wire of fulcrum narrows, can reduces the possibility of the broken string of the lead-in wire near tie point with tie point.Therefore, it is possible to improve the reliability of the connection of lead-in wire and substrate.

Further, also can be, illumination light source, also possess: the framework being configured with the elongate of substrate in inside; And lamp holder, be arranged on the end of the length direction of framework, lamp holder has, the cap body of tubular and as attaching parts, the bayonet peg that is arranged on this cap body, at the first interarea, be configured with light-emitting component and for making the lamp circuit of this light-emitting component luminescence, tie point is, the position be electrically connected with lamp circuit.

Accordingly, the tie point of bayonet peg and substrate can be connected by lead-in wire.The reliability of connection now can be improved, therefore, also can improve the reliability of the supply of the electric power externally to lamp circuit and light-emitting component.

And, also can be, in exposing of bayonet peg, the part of the opening of cap body is provided with the second through hole, one end of lead-in wire, be connected with bayonet peg by the second through hole, cap body has the second guide surface, and this second guide surface is used for described one end of lead-in wire to be directed to the second through hole.

Accordingly, lead-in wire is connected with bayonet peg by the second through hole, therefore, it is possible to the movable range of the lead-in wire of restriction coupling part.Therefore, it is possible to reduce the load being applied to coupling part, the possibility that the broken string that can reduce lead-in wire occurs.And then, cap body is provided with guide surface, therefore, without the need to trickle operation, and easily can by lead-in wire through the second through hole.Therefore, it is possible to improve the reliability of the connection of lead-in wire and bayonet peg.

Further, also can be, the other end of lead-in wire, welds with tie point.

Accordingly, can by easy with tie point for lead-in wire and to be fasteningly electrically connected.

[the second effect]

The illumination light source that embodiment 4 of the present utility model relates to possesses: the substrate being configured with the elongate of light-emitting component; The framework of the elongate of substrate is configured with in inside; Lamp holder, has the cap body of the end of the length direction being arranged on framework and is arranged on the bayonet peg of this cap body; And lead-in wire, one end of this lead-in wire is connected with bayonet peg, and the other end of this lead-in wire is connected with substrate, and for supplying electric power to light-emitting component, at substrate, is provided with the space for making lead-in wire pass to the direction of this substrate through.

So, the lead-in wire 60 be connected with tie point, through through hole 140, accordingly, its routing path is limited.That is, take tie point as the movable range of the lead-in wire 60 of fulcrum, compared with situation about directly will connect for electrical prongs 320 and tie point, the situation through through hole 140 is narrower.Therefore, the load (tension force) being applied to the other end (with the coupling part of tie point) of lead-in wire 60 dies down, accordingly, and the possibility that the broken string that can reduce lead-in wire 60 occurs.

In the straight tube LED 1B that the present embodiment relates to, in the mode that the end face of substrate 11B is abutted with the bearing surface 351 of cap body 310, power supply lamp holder 30B is connected with LED module 10B.Therefore, when substrate 11B does not arrange the space for making lead-in wire 60 pass, meeting leaded 60 is sandwiched in the possibility between the end face of substrate 11B and bearing surface 351.In the nipped situation of lead-in wire 60, load (tension force) is applied to lead-in wire 60, the possibility of the broken string generation of meeting leaded 60.

Further, even if when the end face of substrate 11B does not abut with bearing surface 351, also leaded 60 possibility between substrate 11B and cap body 310 can be sandwiched in.Therefore, need the routing path limiting lead-in wire 60, suppress the generation of the clamping of lead-in wire 60.

So, as the present embodiment, recess 150 is set at substrate 11B, thus the routing path of lead-in wire 60 can be limited.Specifically, when power supply being connected with LED module 10B with lamp holder 30B, lead-in wire 60 can be made to hide space to being formed by recess 150.

So, the space of hiding of lead-in wire 60 can be formed by recess 150.For recess 150, such as, formed, therefore, it is possible to easily formed by a part for the end of incised notch substrate 11B.Therefore, it is possible to form hiding of lead-in wire 60 with easy structure to use space.

Accordingly, the possibility that the clamping that can reduce lead-in wire 60 occurs, and then, the possibility that the broken string that can reduce lead-in wire 60 occurs.Therefore, it is possible to improve the reliability of the connection of lead-in wire 60 and substrate 11B.

Further, the end face of substrate 11B is provided with recess 150, therefore, after being connected with lead-in wire 60 for electrical prongs 320 and substrate 11B, lead-in wire 60 can being made to pass and use space by hiding of being formed of recess 150.Therefore, do not need when connecting lead wire 60 to consider routing path, therefore, easily and the connection of lead-in wire 60 can be realized accurately.

Further, the end face of the length direction of substrate 11B being provided with recess 150, therefore, when inserting LED module 10B to power supply with lamp holder 30B, lead-in wire 60 can being arranged, to be filled in by lead-in wire 60, by lead-in wire 60 through the space formed by recess 150.That is, lead-in wire 60 easily can be made to use space through hiding.

As mentioned above, the illumination light source that the present embodiment relates to possesses: the substrate being configured with the elongate of light-emitting component; The framework of the elongate of substrate is configured with in inside; Lamp holder, has the cap body of the end of the length direction being arranged on framework and is arranged on the bayonet peg of this cap body; And lead-in wire, one end of this lead-in wire is connected with bayonet peg, and the other end of this lead-in wire is connected with substrate, and for supplying electric power to light-emitting component, at substrate, is provided with the space for making lead-in wire pass to the direction of this substrate through.

Accordingly, be provided with at substrate, for the space making lead-in wire pass to the direction of through substrate, therefore, it is possible to reduce the possibility going between and be sandwiched between substrate and cap body.Hiding with space of lead-in wire is set at substrate, thus the routing path of lead-in wire can be limited, that is, the movable range of lead-in wire can be diminished.Therefore, it is possible to suppress the load (tension force) large when connecting lamp holder and substrate to be applied to lead-in wire, the possibility that the broken string that can reduce lead-in wire occurs.Therefore, it is possible to improve the reliability of the connection of lead-in wire and substrate.

Further, also can be, space formed by from the end face of substrate to the first recess of the inner recess of this substrate.

Accordingly, according to arranging the so easy structure of recess at end face, can be formed to hide and use space.Further, formed at the end face of substrate and hide with space, therefore, after connecting bayonet peg and substrate by lead-in wire, lead-in wire can be disposed through to hide and use space.Therefore, when connecting bayonet peg and substrate, do not need the routing path considering lead-in wire, therefore, easily and the connection of lead-in wire can be realized accurately.

Further, also can be, the first recess cave in from the end face of the length direction of substrate to the length direction of substrate.

Accordingly, what form recess at the end face of the length direction of substrate hides with space, therefore, when lamp holder is inserted into substrate, can in the mode that lead-in wire 60 is filled in, and hide and use space hiding.Therefore, easily lead-in wire can be arranged.

Further, also can be, cap body has, the plane parallel with the opening surface of this cap body, and the end face of the length direction of substrate, abuts with plane.

Accordingly, substrate is abutted with lamp holder, thus the direction of substrate generation thermal expansion can be collected in a side of the length direction of substrate.That is, when a side of the length direction of substrate abuts with lamp holder, the direction of substrate generation thermal expansion can be collected in the opposing party of the length direction of substrate.Therefore, such as, the end of supply side is abutted with lamp holder, thus the position of the light-emitting component of the supply side because of the expansion of substrate can be suppressed to change, therefore, it is possible to make the luminous position of illumination light source stablize.

Further, also can be that, in the region relative with the first recess of plane, be provided with the second recess, lead-in wire is arranged to, through the wiring space formed by the first recess and the second recess.

Accordingly, also form recess in lamp holder side, therefore, it is possible to it is more than needed to make the routing path of lead-in wire have after connection lamp holder and substrate.After connection lamp holder and substrate, the nipped possibility that goes between does not exist.Further, in order to disperse the tension force being applied to lead-in wire, preferably, the free degree of the routing path of lead-in wire is high.Therefore, form recess in lamp holder side, thus the large space of wiring can be guaranteed, the free degree of the routing path of lead-in wire can be improved.

And, also can be, substrate has, the first interarea respect to one another and the second interarea, bayonet peg, be positioned at the first interarea side, the other end of lead-in wire, be connected with the tie point of the first interarea, at substrate, also be formed with through hole, lead-in wire is arranged to, and reaches tie point successively from bayonet peg through the first interarea side, wiring space, the second interarea side and the first through hole.

Accordingly, go between through through hole, accordingly, its routing path is limited.That is, take tie point as the movable range of the lead-in wire of fulcrum, compared with situation about directly will connect for electrical prongs and tie point, the situation through through hole is narrower.Therefore, the load (tension force) being applied to the other end (with the coupling part of tie point) of lead-in wire dies down, accordingly, and the possibility that the broken string that can reduce lead-in wire occurs.

And show in the present embodiment, the structure that lead-in wire 60 is connected with the surface of substrate 11B, but also can be, lead-in wire 60 be connected with the back side.Such as, for the metal line be electrically connected with lamp circuit 14, the situation that can be electrically connected from the rear side of substrate 11B, can will go between 60, be connected with the back side of substrate 11B.In the case, through hole 140 can not be set at substrate 11B.

Further, show in the present embodiment, a recess 150 is set at substrate 11B, make two lead-in wires 60 through the structure in the space formed by a recess 150, but also can be hide by each lead-in wire formation and use space.Specifically, two recesses 150 can be set at substrate 11B.Now, two recesses 353 also can be set in cap body 310.

Further, show in the present embodiment, the structure of the recess 150 of slightly rectangle is set, but the shape of recess 150 is not limited only to this.Such as, recess 150 also can be, slightly semicircle.Recess 150, has the size that can be formed for the space making lead-in wire 60 pass.

Further, in the present embodiment, lead-in wire 60 is arranged to, and through the outside of the side of substrate 11B, specifically, through wiring space, but also can be, be arranged to through the through hole different from through hole 140.That is, also three through hole different from through hole 140 can be set at substrate 11B.And, also lead-in wire 60 can be arranged as, from for electrical prongs 320, pass the first interarea side of substrate 11B, the 3rd through hole, the second interarea side and through hole 140 successively, reach tie point.

Further, show in the present embodiment, guide surface is, the example of the plane parallel with the opening surface of cap body 310, but also can be, guide surface is, face shown in Figure 25 A to Figure 25 C, that tilt relative to the plane parallel with opening surface.At this, Figure 25 A to Figure 25 C is sectional view or the plane of other example that the power supply lamp holder that embodiment 4 of the present utility model relates to is shown.

As Figure 25 A illustrates, guide surface 360a, tilts relative to the plane parallel with the opening surface of cap body 310a.Specifically, guide surface 360a is, with far away with through hole 321, more close to the mode of the opening surface of cap body 310a, and the face tilted relative to opening surface.In other words, guide surface 360a is, with the inner surface from cap body 310a more close to center line, and the face more tilted close to the mode of bottom surface.That is, guide surface 360a is, from the inner surface of cap body 310a towards the acclivitous plane in side of through hole 321.The elongated surfaces of guide surface 360a, such as, reaches the opening portion of through hole 321.Inclination angle is, such as, relative to opening surface, 1 to 85 degree, as an example, is 45 degree.

So, the guide surface 360a of inclination is arranged on cap body 310a, thus lead-in wire 60 more can be made to be directed to through hole 321 smoothly.

Further, guide surface also can be, multiple planes of mutually different inclination.Such as, the guide surface 360b shown in Figure 25 B can comprise, the plane parallel with the opening surface of cap body 310b and inclined plane.Equally, guide surface 360b can comprise, multiple inclined planes of mutually different inclination.

Further, guide surface, may not be plane.Such as, the guide surface 360c shown in Figure 25 C is, take the end close with through hole 321 as the concave surface of the taper of front extreme direction.Specifically, guide surface 360c is, from the inner surface of cap body 310c towards the face of the acclivitous taper in side of through hole 321.Such as, the concave surface of taper is, forms the face of a part for conical side surface.Guide surface 360c is set to cone-shaped, thus lead-in wire 60 more can be made to be directed to through hole 321 smoothly.

Further, the guide surface for guiding the other end of lead-in wire to the first through hole being arranged on substrate also can be set.

Figure 26 is the sectional view of other example that the substrate 11B1 that embodiment 4 of the present utility model relates to is shown.And Figure 26 illustrates, parallel with the length direction of substrate 11B1 and with to the vertical cross section of the interarea of substrate 11B1.

Guide surface 170 is, an example of the first guide surface, is arranged on the position corresponding with the position of through hole 140 of substrate 11B1.Specifically, guide surface 170, along the week of the opening of through hole 140 a part and arrange.Such as, guide surface 170, along among the week of the opening of through hole 140, the part far away with the end face of the length direction of substrate 11B1 and arranging.

Guide surface 170 is, as Figure 26 illustrates, and the surface parallel with the through direction of through hole 140.Guide surface 170 can be plane, or, also can be the curved surface of the shape of the opening along through hole 140.Such as, the opening of through hole 140 is circle, and therefore, guide surface 170 also can be the face of the shape of the side along cylinder.

Figure 27 A to Figure 27 C is the sectional view of other example of the connection operation that the lead-in wire 60 that embodiment 4 of the present utility model relates to is shown.And Figure 27 A to Figure 27 C illustrates, parallel with the length direction of substrate 11B1 and vertical with the interarea of substrate 11B1 cross section.

As Figure 27 A illustrates, lead-in wire 60, is directed to guide surface 170 from the end face side of the length direction of substrate 11B1.And as Figure 27 B illustrates, the other end of lead-in wire 60, contacts with guide surface 170, the through hole 140 to substrate 11B1 bends.Filled in same as before by lead-in wire 60, accordingly, as Figure 27 C illustrates, the other end of lead-in wire 60, through through hole 140, is welded with tie point by solder 131.

So, lead-in wire 60 contacts with guide surface 170, and accordingly, the direction of insertion of lead-in wire 60, the direction to the through hole 140 towards substrate 11B1 bends.Specifically, lead-in wire 60, after contacting, bends along guide surface 170 with guide surface 170.That is, lead-in wire 60, is in progress along the direction parallel with guide surface 170.Accordingly, lead-in wire 60 can be made to pass through through hole 140.

As mentioned above, in the illumination light source that the variation of the present embodiment relates to, substrate is also passable, has the first guide surface of the other end for guiding lead-in wire to the first through hole at the second interarea.

Accordingly, substrate is provided with guide surface, therefore, lead-in wire easily can be made by the first through hole.Therefore, it is possible to improve the reliability of the connection of lead-in wire and substrate.

And, show the example that guide surface 170 is the plane parallel with through hole 140, but, be not limited only to this.Such as, guide surface 170 also can be, relative to the through direction of through hole 140 and the plane tilted.Further, guide surface 170 also can be, the concave surface of taper.

Further, guide surface 170 also can be, on the through direction of through hole 140, forms the face that the side of the substrate 11B1 of through hole 140 is extended.That is, guide surface 170 also can be, with the all-in-one-piece face, side of the substrate 11B1 of formation through hole 140.

Further, guide surface 170 may not be a part of substrate 11B1, and can be the face different from substrate 11B1.

Further, show in the present embodiment, LED module 10B, exceed the structure of framework 20, but also can be, LED module 10B, be incorporated in framework 20.

Further, show in the present embodiment, straight tube LED, using an example as illumination light source, but also can be, bulb-shaped LED.

Now, such as, attaching parts are, are configured with the LED-baseplate of LED element.One end of lead-in wire, is connected with the connector being arranged on LED-baseplate.Or one end of lead-in wire, welds with LED-baseplate.Connector or solder separately, conduct with LED element, can to the electric power of LED element supply from outside.

Further, the substrate be connected with the other end of lead-in wire is configured with the circuit substrate of lamp circuit.At circuit substrate, arrange the first through hole, the other end of lead-in wire is connected with the tie point of circuit substrate by the first through hole.And circuit substrate, is connected with other lead-in wire, by these other lead-in wire, the electric power from outside is supplied to lamp circuit.

Now, LED-baseplate, is positioned at the first interarea side of circuit substrate, specifically, is positioned at the tie point side be connected with the other end of lead-in wire.Lead-in wire is arranged to, and from LED-baseplate, passes the first interarea side of circuit substrate, the second interarea side and the first through hole successively, reaches tie point.

Accordingly, even if when bulb-shaped LED, be connected with tie point through the first through hole, therefore, be that the movable range of the lead-in wire of fulcrum narrows with tie point, the possibility of the broken string of the lead-in wire near tie point can be reduced.Therefore, it is possible to improve the reliability of the connection of lead-in wire and substrate.

And, show in the present embodiment, through hole 140 is set at the substrate 11B of an example as flat board, thus improve the structure of the reliability of the connection of substrate 11B and lead-in wire 60.To this, in the present embodiment, through hole 321 is being set for electrical prongs 320, thus also can improving for the reliability of electrical prongs 320 with the connection of lead-in wire 60.

That is, in the present embodiment, also can be, attaching parts be, are configured with light-emitting component and for making the substrate of the elongate of the lamp circuit of this light-emitting component luminescence, illumination light source also possesses: the framework being configured with the elongate of substrate in inside; And be arranged on the lamp holder of end of length direction of framework, lamp holder has, the cap body of tubular and as flat board, the bayonet peg that is arranged on this cap body.

Specifically, for electrical prongs 320 also, a dull and stereotyped example.Now, substrate 11B, becomes an example of attaching parts.Such as, as Figure 22 illustrates, for the first interarea of electrical prongs 320 and the second interarea be, orthogonal with the interarea of substrate 11B and parallel with the length direction of substrate 11B face.Specifically, the first interarea for electrical prongs 320 is, towards the interarea at the center of cap body 310, the second interarea for electrical prongs 320 is, towards the interarea of the side of cap body 310.

As Figure 22 illustrates, lead-in wire 60 is arranged to, and from substrate 11B, passes the first interarea side of confession electrical prongs 320, the second interarea side and through hole 321 successively, reaches tie point.Lead-in wire 60, is connected with the tie point of the first interarea side for electrical prongs 320.Specifically, lead-in wire 60, welds with the first interarea for electrical prongs 320 through through hole 321.

So, through hole 321 is being set for electrical prongs 320, thus also can improving for the reliability of electrical prongs 320 with the connection of lead-in wire 60.That is, be connected with tie point through the through hole 321 be arranged on for electrical prongs 320, therefore, be that the movable range of the lead-in wire 60 of fulcrum narrows with tie point, the possibility of the broken string of the lead-in wire 60 near tie point can be reduced.Therefore, it is possible to improve the reliability of lead-in wire 60 and the connection for electrical prongs 320.

(variation of embodiment 4)

Then, the straight tube LED that the variation of embodiment 4 of the present utility model relates to is described.In example 4, describe the structure that recess is set at the end face of the length direction of substrate, but also can be, recess is set at the end face in the short direction of substrate.That is, in the illumination light source that the variation of embodiment 4 of the present utility model relates to, the first recess, caves in from the end face in the short direction of substrate to the short direction of substrate.

Below, be described centered by difference from Example 4.

Figure 28 and Figure 29 is the sectional view of a part for the example that the straight tube LED 1B2 that the variation of embodiment 4 of the present utility model relates to is shown.And Figure 29 illustrates, the F1-F1 cross section of Figure 28.

As Figure 28 illustrates, in the straight tube LED 1B2 that embodiment 4 variation of the present utility model relates to, compared with embodiment 4, difference is, replaces substrate 11B and possesses substrate 11B2, replaces cap body 310 and possesses cap body 310B2.

Substrate 11B2, compared with the substrate 11B related to embodiment 4, difference is, replaces recess 150 and arranges recess 150a.

Recess 150a is, an example of the first recess, formed for make lead-in wire 60 on the direction (Z-direction) of through substrate 11B2 through space.As Figure 28 illustrates, recess 150a, caves in from the end face in the short direction of substrate 11B2 to the short direction of substrate 11B2.Such as, recess 150a, is formed by a part of the end face incised notch substrate 11B2 in the short direction of the substrate 11B2 from rectangle.

Recess 150a, is arranged on the end of the length direction of substrate 11B2.Specifically, recess 150a, is arranged on a part of substrate 11B2 and the part in cap body 310B2.Such as, as Figure 28 illustrates, recess 150a, is arranged between the end face of the length direction of substrate 11B2 and through hole 140.And, form the part of recess 150a, be not limited only to this.

Recess 150a is, as Figure 28 illustrates, and the slightly recess of rectangle.Such as, the degree of depth (the short direction of substrate 11B2) of recess 150a is, 0.5 to 12mm.Further, the width (length direction of substrate 11B2) of recess 150a is, 0.5 to 5mm.And, also the degree of depth of recess 150a can be set to, 2 to 49% of the width of substrate 11B2.

Cap body 310B2 is, is arranged on an example of the first cap body of the end of a side of framework 20.Cap body 310B2, compared with the cap body 310 related to embodiment 4, difference is, does not arrange recess 353.That is, in the variation of embodiment 4, between the end face and cap body 310B2 of the length direction of substrate 11B2, do not form wiring space.

Bearing surface 351a is, the face of the end face abutting of the length direction of substrate 11B2.Such as, bearing surface 351a is, the face parallel with the opening surface of cap body 310B2.As Figure 28 illustrates, the end face of the length direction of substrate 11B2 comprehensive, abuts with bearing surface 351a.Accordingly, compared with embodiment 4, the area that substrate 11B2 contacts with cap body 310B2 is large, therefore, even if when thermal expansion occurs substrate 11B2, also more can suppress the expansion to power supply lamp holder 30B2 side.

In the variation of embodiment 4 of the present utility model, as shown in figure 29, lead-in wire 60 is arranged.That is, lead-in wire 60 is arranged to, through the space formed by recess 150a.Specifically, lead-in wire 60 is arranged to, and from for electrical prongs 320, through the first interarea side of substrate 11B2, the space formed by recess 150a, the second interarea side and through hole 140, reaches tie point.

Now, lead-in wire 60, when connecting power supply with lamp holder 30B2 and substrate 11B2, through the space formed by recess 150a (hiding with space).This is because, when connecting power supply with lamp holder 30B2 and substrate 11B2, the cause that the possibility that the clamping going between 60 occurs is the highest.Therefore, after connection power supply is with lamp holder 30B2 and substrate 11B2, lead-in wire 60, also can not through the space formed by recess 150a.Such as, lead-in wire 60, through the space that formed by recess 150a at least partially.

As mentioned above, in the straight tube LED 1B2 that the variation of embodiment 4 of the present utility model relates to, be also provided with hiding with space of lead-in wire 60, therefore, it is possible to reduction lead-in wire 60 is sandwiched in the possibility between substrate 11B2 and cap body 310B2.Therefore, it is possible to suppress the large load (tension force) when connecting power supply lamp holder 30B2 and substrate 11B2 to be applied to lead-in wire 60, the possibility that the broken string that can reduce lead-in wire 60 occurs.Therefore, it is possible to improve the reliability of the connection of lead-in wire 60 and substrate 11B2.

Then, the straight tube LED that other variation of embodiment 4 of the present utility model relates to is described.In the variation of embodiment 4, describe the structure that recess is set at the end face in the short direction of substrate, but also can be, through hole is set at substrate.That is, in the illumination light source that other variation of embodiment 4 of the present utility model relates to, space, is formed by the 3rd through hole of through substrate.

Below, be described centered by difference from Example 4.

Figure 30 is the sectional view of a part for the example that the straight tube LED 1B3 that other the variation that embodiment 4 of the present utility model relates to relates to is shown.

As Figure 30 illustrates, in the straight tube LED 1B3 that other variation of embodiment 4 of the present utility model relates to, compared with the variation of embodiment 4, difference is, replaces substrate 11B2 and possesses substrate 11B3.Substrate 11B3, compared with the variation of embodiment 4, difference is, replaces recess 150a and arranges through hole 150b.

Through hole 150b is, an example of the 3rd through hole, formed for make lead-in wire 60 on the direction (Z-direction) of through substrate 11B3 through space.Through hole 150b, is arranged on the end of the length direction of substrate 11B3.Specifically, through hole 150b is, is arranged on a part of substrate 11B3 and the part in cap body 310B2.

Such as, through hole 150b, is arranged between the end face of the length direction of substrate 11B3 and through hole 140.And the part that through hole 150b is set up, is not limited only to these.

Through hole 150b is, as Figure 30 illustrates, and the slightly through hole of rectangle.Such as, the length (the short direction of substrate 11B3) of through hole 150b is, 0.5 to 23mm.Further, the width (length direction of substrate 11B3) of through hole 150b is, 0.5 to 5mm.And, also the length of through hole 150b can be set to, 2 to 92% of the width of substrate 11B3.

Now, also the breach reaching through hole 150b can be set at substrate 11B3.Make lead-in wire 60 reach through hole 150b from the end face of substrate 11B3 by breach, thus easily can arrange lead-in wire 60.That is, with make the end of lead-in wire 60 through through hole 150b situation compared with, make the part beyond the end of lead-in wire 60 (covered part) easier through the situation of breach.

In other variation of embodiment 4, as Figure 22 illustrates, arrange lead-in wire 60.That is, lead-in wire 60 is arranged to, through the space formed by through hole 150b (hiding with space).Specifically, lead-in wire 60 is arranged to, and from for electrical prongs 320, through the first interarea side of substrate 11B3, the space formed by through hole 150b, the second interarea side and through hole 140, reaches tie point.

As mentioned above, in the straight tube LED 1B3 that other variation of embodiment 4 of the present utility model relates to, be also provided with hiding with space of lead-in wire 60, therefore, it is possible to reduction lead-in wire 60 is sandwiched in the possibility between substrate 11B3 and cap body 310B2.Hide and formed by through hole 150b with space, therefore, compared with the situation of recess, the routing path of lead-in wire 60 is more limited.

Therefore, large load (tension force) can be suppressed to be applied to lead-in wire 60 when connecting power supply lamp holder 30B2 and substrate 11B3, the possibility that the broken string that can reduce lead-in wire 60 occurs.Therefore, it is possible to improve the reliability of the connection of lead-in wire 60 and substrate 11B3.

As mentioned above, in the illumination light source that the variation of embodiment 4 of the present utility model relates to, the first recess is also passable, caves in from the end face in the short direction of substrate towards the short direction of substrate.

Accordingly, can be formed to hide use space to arrange the such simple structure of recess at end face.Further, formed at the end face of substrate and hide with space, therefore, after connecting bayonet peg and substrate by lead-in wire, so that can lead-in wire be arranged through the mode hidden with space.That is, when connecting bayonet peg and substrate, do not need the routing path considering lead-in wire, therefore, easily and the connection of lead-in wire can be realized accurately.Now, for recess, be not only formed in the end face of the length direction of substrate, also can be formed in the end face in short direction, therefore, it is possible to improve the free degree of design.

Further, space is also passable, is formed by the 3rd through hole of through substrate.

Accordingly, hide and formed by through hole with space, therefore, the routing path of lead-in wire is more limited.Therefore, it is possible to the possibility that the broken string more reducing lead-in wire occurs, the reliability of the connection of lead-in wire and substrate can be improved.

And, also can be, substrate has, the first interarea respect to one another and the second interarea, bayonet peg, be positioned at the first interarea side, the described other end of lead-in wire, is connected with the tie point of the first interarea, at substrate, also be formed with the first through hole, lead-in wire is arranged to, and reaches tie point successively from bayonet peg through the first interarea side, space, the second interarea side and the first through hole.

Accordingly, go between through the first through hole, thus limit its routing path.That is, take tie point as the movable range of the lead-in wire of fulcrum, and directly connect bayonet peg compared with the situation of tie point, the situation through the first through hole is narrower.Accordingly, the load (tension force) being applied to the other end (with the coupling part of tie point) of lead-in wire dies down, therefore, it is possible to the possibility that the broken string reducing lead-in wire occurs.

Further, illustrate that LED module 10B exceeds the structure of framework 20 in the present embodiment, but also can be, LED module 10B, be incorporated in framework 20.

(embodiment 5)

First, the straight tube LED that embodiment 5 of the present utility model relates to is described.And the straight tube LED that the present embodiment relates to is, replace an example of the illumination light source of straight-pipe fluorescent lamp in the past.

[overall structure of straight tube LED]

First, an example of the structure of the straight tube LED related to for the present embodiment, utilizes Figure 31 to be described.

Figure 31 is the general survey oblique view of the example that the straight tube LED that embodiment 5 of the present utility model relates to is shown.As Figure 31 illustrates, straight tube LED 1C possesses, the framework 20 of LED module 10C, elongate, the power supply lamp holder 30B fixed respectively in the end of the length direction (tube axial direction) of framework 20 and non-powered lamp holder 40B and lead-in wire 60.Straight tube LED 1C is, such as, the straight tube LED of 40 types, lamp total length is about 1200mm.

Below, each structure member of straight tube LED 1C is described in detail.

[LED module]

As Figure 31 illustrates, LED module 10C is, the light source of straight tube LED 1C is configured in framework 20.At this, LED module 10C is configured to, and end is given prominence to from framework 20.

Figure 32 is the sectional view parallel with tube axial direction of the straight tube LED that embodiment 5 of the present utility model relates to.Further, Figure 33 is the plane of a part for the example that the LED module that embodiment 5 of the present utility model relates to is shown.

The LED module 10C that the present embodiment relates to is, the light emitting module of (SMD:Surface Mount Device) type is installed on surface, possesses substrate 11C, is installed in multiple LED element 12 of substrate 11C and the lamp circuit 14 for the multiple LED element 12 of lighting.Below, be described centered by difference from Example 1.

At this, the area in the cross section of the substrate 11C of the opening surface of the length direction end of framework 20, than framework 20 length direction central portion, the cross section of parallel with described opening surface substrate 11C is little.

For the detailed construction of substrate 11C, be described later.

[framework]

Framework 20 is, similarly to Example 1, covering the diffuser with the elongate of light transmission of LED module 10C, as Figure 31 illustrates, in the present embodiment, is the outer tube of the straight tube-like be made up of the elongate barrel having opening at both ends.Framework 20, can be made up of glass.

At this, in the length direction end of the framework 20 be made up of glass tube, there is so-called glass and accumulate.This is because what occur to prevent the slight crack etc. because of glass end face breaks, in the manufacturing process of glass tube, carry out the cause of end face reprocessing (friction treatment) based on heating.

But as Figure 32 illustrates, the end face of the glass tube after described friction treatment, particularly, the glass grown from the end face of glass tube to inwall accumulates, and causes the interior shape making glass tube to change.Specifically, the thickness of pipe of the length direction end of framework 20 is larger than the thickness of pipe of the length direction central portion of framework 20.

[substrate]

Then, for the substrate 11C that the present embodiment relates to, more detailed construction is described.The shape of the substrate 11C of the LED module 10C that the present embodiment relates to is, avoid following situation, that is, interference with substrate 11C in the end that the thickness of pipe after friction treatment becomes large framework 20, thus cause the configuration precision of LED module 10C and the configuration free degree damaged.

Figure 34 is the plane of the straight tube LED that embodiment 5 of the present utility model relates to.Substrate 11C is, such as, length is 1150 to 1200mm (length direction), and width is 5 to 25mm (short direction), and thickness is 0.3 to 2.0mm.At the interarea of substrate 11C, as Figure 33 illustrates, lamp circuit 14 and multiple LED element 12 be arranged be configured in substrate 11C length direction on.And in the longitudinal direction, substrate 11C is longer than framework 20.

The end of one side of the length direction of substrate 11C, is covered by power supply lamp holder 30B.Such as, substrate 11C is configured to, and end is given prominence to from framework 20, and at least outstanding part, is covered by power supply lamp holder 30B.

Further, as Figure 34 illustrates, lead-in wire 60 is arranged to, through through hole 140.Through hole 140 is, for the through hole welded.Such as, at first interarea of substrate 11C, the week along the opening of through hole 140 is provided with metal electrode.That is, the tie point of substrate 11C is, the opening portion to the first interarea of through hole 140.

Specifically, the other end of lead-in wire 60 is welded as, and through through hole 140, is connected with metal electrode.Specifically, solder is set to, and covers the opening of through hole 140, and the end of lead-in wire 60 (exposed portion of metal) is electrically connected with metal electrode.

At this, as Figure 34 illustrates, the area in the cross section of the substrate 11C of the opening surface of the length direction end of framework 20, than framework 20 length direction central portion, the cross section of parallel with described opening surface substrate 11C is little.More particularly, the short direction in the region of the substrate 11C intersected at the described opening surface with framework 20, is formed with breach.That is, breach, is formed from the both sides on the long limit of substrate 11C.In other words, breach is formed, from two long limits of substrate 11C separately, that is, more particularly, from two sides orthogonal with the short direction of substrate 11C separately, along short direction incised notch substrate 11C.

According to described notch geometry, can prevent following situation, that is, interferenceing with substrate 11C in the end that the thickness of pipe becomes large framework 20 because glass accumulates, thus causes the configuration precision of LED module 10C and configure the free degree damaged.

Now, the length (the short direction of substrate 11C) of a breach is, 1 to 20mm.And, also the length of a breach can be set to, 10 to 40% of the width of substrate 11C.Further, two breach also can be mutually different shapes.
