Detailed description of the invention

In order to further understand feature of the present invention, feature and technology contents, refer to following detailed description for the present invention and accompanying drawing, appended accompanying drawing only provides reference and explanation use, is not used to limit the present invention.

The invention provides a kind of LED lamp tube, as Fig. 1 ~ Figure 7 shows that the first embodiment of the present invention, is then the second embodiment of the present invention as shown in Figure 8, Figure 9.

As shown in Figure 1, the first embodiment of LED lamp tube of the present invention comprises light-transmitting tube body 1, circuit board 2, at least one conduction convex body 3 and at least one light-emitting component 6, and preferably also can comprise two end cap 4 and supporting constructions 5.Wherein, the hollow tube that light-transmitting tube body 1 is made for isolation material, and can for light penetration.

As shown in Figure 1 to 4, it is accommodating and be fixed in light-transmitting tube body 1 that surface 201 has the circuit board 2 of a conductive layer 21, and it can be a rectangular panel body with four edges, in the present embodiment, circuit board 2 is elongated, thus has two long limits and belongs to two minor faces at circuit board 2 two ends.Circuit board 2 is extended with at least one conduction convex body 3, and make extended conduction convex body 3 be exposed to outside light-transmitting tube body 1, in the present embodiment, the two ends (two minor faces) of circuit board 2 are respectively extended with two conduction convex bodys 3 and protrude from the two ends of light-transmitting tube body 1 respectively, can electrically be plugged in lamp holder (not shown).Conduction convex body 3 forms for being extended by circuit board 2, therefore, the surface 201 of conduction convex body 3 also has a conductive layer 21a, that is: the conductive layer 21a on conduction convex body 3 surface 201 extends the conductive layer 21 from circuit board 2 surface 201, therefore conductive layer 21 and conductive layer 21a electrically communicate each other, therefore, the present invention can electrically be plugged in lamp holder (not shown) by the conduction convex body 3 extended from circuit board 2, thus must welding lead (not shown) again, there is the effect being easy to manufacture and be easy to assemble.In addition, aforesaid conductive layer 21,21a can be Copper Foil.

Light-emitting component 6 can be LED element, is electrically to be welded with multiple light-emitting component 6 on the circuit board 2 in the present embodiment, and as shown in the figure, light-emitting component 6 is electrically welded in the conductive layer 21 on circuit board 2 surface 201.

As shown in Figure 5, at least one side of each conduction convex body 3 can also be coated with a conductive metal layer 31, to promote the electric conductivity of conduction convex body 3, then a conductive metal layer 31 is coated with respectively at the dual-side of each conduction convex body 3 in the present embodiment, and conductive layer 21 is electrically connected between two conductive metal layers 31, the present invention does not limit.

Two end caps 4 are socketed on the two ends of light-transmitting tube body 1 respectively, each end cap 4 is for making with isolation material and offering two perforation 41, as shown in Figure 1, two conduction convex bodys 3 of one end of circuit board 2 are interspersed in two perforation 41 of a wherein end cap 4 and expose, two conduction convex bodys 3 of the other end of circuit board 2 are interspersed in two perforation 41 of wherein another end cap 4 and expose, the convex body 3 that namely respectively conducts electricity can locally be exposed to outside end cap 4, enable strong fix lives each conduction convex body 3, thus is beneficial to and is electrically plugged in lamp holder.

As shown in Fig. 1 ~ Fig. 3 and Fig. 6, the supporting construction 5 of first embodiment of the invention comprises multiple support chip 51, between the inner edge that each support chip 51 is supported in circuit board 2 and light-transmitting tube body 1 (see Fig. 3 and Fig. 6), in the present embodiment, support chip 51 is semicircular in shape, but not as limit.In addition, support chip 51 offers two opposite edges (two long limits) that two draw-in groove 511, two draw-in grooves 511 are snapped in circuit board 2 respectively, makes each support chip 51 all be fixed on the below of circuit board 2.
