In each embodiment of the utility model, the mode of the glass lamp strengthening of the LED straight lamp proposed can make chemically or physics mode does secondary operations strengthening to glass.

Making chemically to make to glass the general principle strengthened is improve the intensity of glass with the composition changing glass surface, its method exchanges with other alkali metal ion and the Na ion of surface layer of glass or K ion, surface forms ion exchange layer, after being cooled to normal temperature, glass is in internal layer tension, outer state by compression, thus reach the object of gaining in strength, include but not limited to high temperature modification ion-exchange, low form ion-exchange, dealkalize method, surface crystallization method, sodium metasilicate reinforcement etc., further illustrate as follows.

1, high temperature modification ion-exchange

In the temperature province between the softening point and transition point of glass, containing Na ₂o or K ₂the glass of O invades in the fused salt of lithium, Na ion in glass or the Li Ion Phase in the fused salt little with their radiuses are exchanged, are then cooled to room temperature, due to containing Li ion top layer with contain Na ion or K ion inner layer expansion coefficient different, surface produces residual pressure and strengthens, simultaneously; Glass neutralization is containing Al ₂o ₃, TiO ₂deng composition time, by ion-exchange, can produce the crystallization that the coefficient of expansion is extremely low, cooled glass surface will produce very large pressure, can obtain the glass of intensity up to 700MPa.

2, low form ion-exchange

Low-temperature ion exchange process is in the humidity province lower than strain point of glass, do ion-exchange with monovalent cation (as K ion) and Na ion than top layer basic ion (as Na ion) also larger ionic radius, make K ion enter the method on top layer.Such as Na ₂o+CaO+SiO ₂system glass, can flood tens hours in the fuse salt of degree more than 400.Low form ion-exchange can be easy to obtain high strength, has processing method and simply, does not damage the glass surface transparency, the feature such as indeformable.

3, dealkalize method

Dealkalize method is in the high-temperature atmosphere containing sulphurous acid gas and moisture, utilizes Pt catalyst treatment glass, Na+ ion is oozed out from surface layer of glass and reacts with sulfurous acid, thus superficial layer becomes rich SiO ₂layer, its result becomes low expansion glass due to top layer, produces compression during cooling.

4, surface crystallization method

Surface crystallization method is different from high temperature modification ion-exchange, but forms low-expansion microcrystal by means of only heat treatment on top layer, thus makes it the method for strengthening.

5, sodium metasilicate reinforcement

Sodium metasilicate reinforcement processes in the aqueous solution of sodium metasilicate (waterglass) under several atmospheric pressure more than 100° centigrade, thus obtain the high strength glass being difficult to scuffing top layer.

Use physics mode glass to be done to the mode strengthened, can include but not limited to, use the mode of coating or change the structure of article.The matrix that coating sprays as required determines kind and the state of coating, can be ceramic tile strengthened coat, acryl coating or glass coating etc., can be liquid or gaseous state coating when being coated with.Change the structure of article, such as, do structural strengthening design in part of easily breaking.

No matter be that chemical mode or physics mode are not limited to single mode and implement above, any one that can mix in physics mode or in chemical mode does any matched combined.

Please refer to Fig. 2 and Figure 12, in an embodiment, the glass lamp of the LED straight lamp that the utility model proposes has structure-reinforced end, is described as follows.Fluorescent tube 1 comprises main part 102 and lays respectively at the end 101 at main part 102 two ends, and lamp holder 3 is sheathed on outside end 101.Wherein, the external diameter of at least one end 101 is less than the external diameter of main part 102.In the present embodiment, the external diameter arranging two ends 101 is all less than the external diameter of main part 102, and the section of end 101 is a plane and parallel with main part 102.Particularly, the two ends of fluorescent tube 1 are by strengthening section process, end 101 forms strengthening section structure, lamp holder 3 is enclosed within the end 101 after strengthening, the difference of lamp holder 3 external diameter and lamp tube main body portion 102 external diameter can be made like this to diminish, even completely equal, namely lamp holder 3 external diameter is equal with main part 102 external diameter and make to have gap to produce between lamp holder 3 and main part 102.The benefit of such setting is, in transportation, packaging support only can not contact lamp holder 3, it can contact lamp holder 3 and fluorescent tube 1 simultaneously, making whole LED straight lamp uniform force, and lamp holder 3 can not be made to become unique stress point, concentratedly to break due to stressed in the position avoiding lamp holder 3 to be connected with lamp tube end 101, improve the quality of product, and have effect attractive in appearance concurrently.

In the present embodiment, lamp holder 3 external diameter is substantially equal with main part 102 external diameter, and tolerance is in positive and negative 0.2mm (millimeter), is no more than at most positive and negative 1mm.

In order to reach the lamp holder 3 external diameter object substantially equal with main part 102 external diameter, according to the thickness of different lamp holders 3, the end 101 after strengthening can be 1mm to 10mm with the difference range of main part 102 external diameter; Or preferred, the end 101 after strengthening can be relaxed to 2mm to 7mm with the difference range of main part 102 external diameter.

In the present embodiment, with reference to Figure 12, seamlessly transit, form a transition part 103 between the end 101 of fluorescent tube 1 and main part 102, the two ends of transition part 103 are all in cambered surface, and namely the two ends of transition part 103 section is vertically arc shaped.Further, cambered surface is between the outer surface and the outer surface of main part 102 of transition part 103, and the arc angle of cambered surface is greater than 90 degree, and the outer surface of end 101 is a continuous surface and still remains parallel with the outer surface of main part 102.

The length of transition part 103 is 1mm to 4mm, if be less than 1mm, then and the insufficient strength of transition part; If be greater than 4mm, then can reduce the length of main part 102, reduce light-emitting area, need the corresponding increase of the length of lamp holder 3 to coordinate with main part 102 simultaneously, cause the material of lamp holder 3 to increase.In other embodiments, then transition part 103 also can not be arc.Please refer to Fig. 5 and Figure 13, Fig. 5 shows the structural representation during connection of the utility model embodiment lamp holder 3 and fluorescent tube 1, and Figure 13 shows the structural representation of the transition part 103 of fluorescent tube 1 in Fig. 5.As shown in Fig. 5 and Figure 13, in the present embodiment, fluorescent tube 1 is employing glass lamp, transition part 103 between main part 102 and end 101, can slightly in by continuous two, there is radius of curvature R 1, the inverted S-shaped curved surface that the cambered surface of R2 is formed, generally speaking, pass between the radius of curvature R 1 of two cambered surfaces and R2 is R1<R2, the proportion R1:R2 of R1 and R2 is 1:1.5 to 1:10, preferably scope is 1:2.5 to 1:5, best scope is 1:3 to 1:4, the present embodiment adopts R1:R2 to be about 1:3, thus, near the transition part 103 (i.e. the recessed transition part 103 upwards of cambered surface shown in Figure 13) of end 101, after intensive treatment, glass is made to be in internal layer tension, the state of outer pressurized, thus reach the object of transition part 103 intensity increasing glass lamp 1.And the transition part 103 (i.e. the recessed downward transition part 103 of cambered surface shown in Figure 13) of close main part 102, after intensive treatment, make glass be in internal layer pressurized, the state of outer tension, thus reach the object of transition part 103 intensity increasing glass lamp 1.

For the standard fluorescent tube of T8, the external diametrical extent of the end 101 after strengthening is 20.9mm to 23mm, if be less than 20.9mm, then the internal diameter of end 101 is too small, causes power supply unit cannot insert in fluorescent tube 1.The external diametrical extent of main part 102 is 25mm to 28mm, if be less than 25mm, then with existing process conditions, inconvenience does strengthening section process to its two ends, if be greater than 28mm, will not meet professional standard.

Please refer to Fig. 3 and Fig. 4, in the utility model one embodiment, the lamp holder 3 of LED straight lamp comprises an insulation tube 302, and is fixedly arranged on heat-conducting part 303 on insulation tube 302 outer peripheral face, and is located at two hollow conductive pins 301 on insulation tube 302.

Please refer to Fig. 5, in the present embodiment, insulation tube 302 one end towards fluorescent tube is stretched out in one end of heat-conducting part 303, bonding by a PUR 6 between the extension (stretching out the part of insulation tube) of heat-conducting part 303 and fluorescent tube 1.Further, lamp holder 3 extends to transition part 103 by heat-conducting part 303, contact closely with transition part 103 by heat-conducting part 303, make heat-conducting part 303 and fluorescent tube 1 bonding by PUR 6 time, do not have PUR 6 and overflow lamp holder 3 and the main body main part 102 remaining to fluorescent tube 1.In addition, insulation tube 302 does not extend to transition part 103 towards one end of fluorescent tube 1, and namely insulation tube 302 keeps certain intervals towards between one end and transition part 103 of fluorescent tube.In the present embodiment, the material of insulation tube 302 does not limit and uses the material such as plastics, pottery, is not mainly the good conductor of electricity under general state.Moreover PUR 6 is a kind of constituents, comprise a kind of material for welding powder, composition is preferably: phenolic resins 2127#, shellac, rosin, calcite in powder, zinc oxide, ethanol etc.In the present embodiment, rosin is a kind of tackifier, has and is dissolved in ethanol, but water-fast characteristic.This PUR 6 under the condition of high-temperature heating, can change its physical state and occurs significantly to expand, reach the effect of solidification, add the stickiness of material own, thus can make lamp holder 3 and fluorescent tube 1 close contact, be convenient to LED straight lamp and realize automated production.In the present embodiment, PUR 6 can present and expands and flow after high-temperature heating, cools the effect that namely can reach solidification subsequently, and when PUR 6 is heated to the temperature of 200 to 250 degree Celsius from room temperature, the volume of PUR will be expanded to original 1 to 1.3 times.Certainly, selecting of the utility model PUR composition is not limited thereto, the composition solidified after also can selecting high-temperature heating to predetermined temperature.Because the utility model PUR 6 can not cause reliability decrease because the heating element heatings such as power supply module form hot environment, can prevent fluorescent tube 1 and the adhesive property of lamp holder 3 in the use procedure of LED straight lamp from reducing, improve long-term reliability.

Particularly, between the inner peripheral surface and the outer peripheral face of fluorescent tube 1 of heat-conducting part 303 extension, be formed with an accommodation space, PUR 6 is filled in (in Fig. 5 position shown in dotted line B) in this accommodation space.In other words, the position that PUR 6 is filled is passed through by the first virtual plane (plane as crossed drawn by dotted line B in Fig. 5) axially vertical with fluorescent tube 1: radially inside direction, in the position of the first virtual plane, sequential is the outer peripheral face of heat-conducting part 303, PUR 6 and fluorescent tube 1.PUR 6 coating thickness can be 0.2mm to 0.5mm, and PUR 6 can expand Post RDBMS, thus contacts with fluorescent tube 1 and lamp holder 3 is fixed on fluorescent tube 1.And between outer peripheral face due to both end 101 and main part 102, there is difference in height, PUR therefore can be avoided to spill in main part 102 part of fluorescent tube, remove follow-up manual wipping process from, improve the output of LED straight lamp.

Add man-hour, by external heat equipment by heat conduction to heat-conducting part 303, and then conduct to PUR 6, PUR 6 is expanded after cooling curing, thus lamp holder 3 to be fixedly bonded on fluorescent tube 1.

In the present embodiment, as shown in Figure 5, insulation tube 302 comprises the first pipe 302a and the second pipe 302b that connect vertically, and the external diameter of the second pipe 302b is less than the external diameter of the first pipe 302a, and the external diameter difference range of two pipes is 0.15mm to 0.3mm.Heat-conducting part 303 is located on the outer peripheral face of the second pipe 302b, and the outer surface of heat-conducting part 303 is concordant with the outer peripheral face of the first pipe 302a, makes the outer surface flat smooth of lamp holder 3, ensures whole LED straight lamp uniform force in packaging, transportation.Wherein, heat-conducting part 303 compares for 1:2.5 to 1:5, i.e. heat-conducting part length along the length of lamp holder axial direction and the axial length of insulation tube 302: insulation tube length is 1:2.5 to 1:5.

In the present embodiment, in order to ensure bonding fastness, the present embodiment arranges the second pipe 302b and is sheathed on outside fluorescent tube 1 at least partly, and accommodation space also comprises the space between the inner surface of the second pipe 302b and end 101 outer surface of fluorescent tube.PUR 6 have be partially filled in mutual overlapping (in Fig. 5 position shown in dotted line A) between the second pipe 302b and fluorescent tube 1, namely part holt melt glue 6 is between the inner surface and the outer surface of end 101 of the second pipe 302b.In other words, the position that PUR 6 is filled in described accommodation space is passed through by one with axial the second vertical virtual plane of fluorescent tube (plane as crossed drawn by dotted line A in Fig. 5): radially inside direction, in the position of the second virtual plane, sequential is heat-conducting part 303, second pipe 302b, PUR 6 and end 101.Spy gives explanation, and in the present embodiment, PUR 6 does not need to fill up above-mentioned accommodation space (as accommodation space in figure can also comprise the space between heat-conducting part 303 and the second pipe 302b) completely.During manufacture, when during coating hot-melt adhesive 6, the amount of PUR suitably can be increased between heat-conducting part 303 and end 101, make in the process of subsequent heat, PUR can flow to due to expansion between the second pipe 302b and end 101, bonds connection after cooling curing and then by both.

Wherein, after the end 101 of fluorescent tube 1 is inserted in lamp holder 3, the axial length that lamp holder 3 part is inserted in the end 101 of fluorescent tube 1 account for heat-conducting part 303 axial length 2/1 to three/3rds between, such benefit is: on the one hand, ensure that hollow conductive pin 301 has enough creep age distances with heat-conducting part 303, both during energising, not easily short circuit makes people get an electric shock and initiation potential; On the other hand, due to the insulating effect of insulation tube 302, the creep age distance between hollow conductive pin 301 and heat-conducting part 303 being strengthened, getting an electric shock and the test of initiation potential more easily by making people during high voltage.

Further, PUR 6, the second pipe 302b for the second pipe 302b inner surface is interposed between PUR 6 and heat-conducting part 303, and the effect that therefore heat conducts to PUR 6 from heat-conducting part 303 can be given a discount.Therefore, with reference to Fig. 4, the present embodiment arranges multiple breach 302c circumferentially arranged at the second pipe 302b towards one end (namely away from one end of the first pipe 302a) of fluorescent tube 1, increase the contact area of heat-conducting part 303 and PUR 6, being beneficial to heat conducts to PUR 6 from heat-conducting part 303 fast, accelerates the solidification process of PUR 6.Meanwhile, when user touches heat-conducting part 303, due to the insulating effect of PUR 6 between heat-conducting part 303 and fluorescent tube 1, can not get an electric shock because fluorescent tube 1 has breakage.

Wherein, heat-conducting part 303 can be the material of various easy heat conduction, is sheet metal, and has consideration attractive in appearance concurrently, such as aluminium alloy in the present embodiment.Heat-conducting part 303 is (or claiming ring-type) in a tubular form, is set in outside the second pipe 302b.Insulation tube 302 can be various insulating materials, but is good to be not easy heat conduction, avoid heat conduction on the power supply module of lamp holder 3 inside, affect the performance of power supply module, the insulation tube 302 in the present embodiment is plastic tube.

In other embodiments, heat-conducting part 303 can also be made up of along the second pipe 302b circumference interval or not spaced sheet metal multiple.

The LED straight lamp of the present embodiment is in time manufacturing, after the end 101 of fluorescent tube 1 is inserted in lamp holder 3, the insulation tube 302 of lamp holder 3 is inserted in a straight lamp head heating solidifying apparatu structure 113 and heats to be fixed together with fluorescent tube 1 by lamp holder 3, please refer to Figure 19, straight lamp head heating solidifying apparatu structure 113, comprises straight tube contact pin gland 1131, gland fixed head 1132, connecting rod 1133, square cylinder 1134, square cylinder fixed mount 1135.When heat fixation is added to LED straight lamp, first LED straight lamp lamp holder 34 metal ferrule is inserted in straight tube contact pin gland 1131, straight tube contact pin gland 1131 is fixed on gland fixed head 1132, and connecting rod 1133 is connected and fixed a fixed head 1132 and square cylinder 1134.After heating, in order to automatically shift out LED straight lamp, connecting rod 1133 is driven by venting by square cylinder 1134, gland fixed head 1132 is retreated, because straight tube contact pin gland 1131 is fixed on gland fixed head 1132, so straight tube contact pin gland 1131 retreats together along with gland fixed head 1132, the straight tube of roasting complete head so just can be made automatically to exit.On another square cylinder 1134 side of being fixed on cylinder fixed mount 1135.
