The specific embodiment
Below will combine accompanying drawing that the present invention is done further detailed description.
See also Fig. 1 and Fig. 2, a kind of light-emitting diode light bar assembly 100 that embodiment of the present invention provides comprises a plurality of light-emitting diode light bars 10.In this embodiment, said light-emitting diode light bar assembly 100 comprises 4 light-emitting diode light bars 10.Be appreciated that in other embodiments the quantity of light-emitting diode light bar 10 also can be two, three, five or the like in the said light-emitting diode light bar assembly 100, concrete quantity can be decided according to needed dimension of light source.
Said each light-emitting diode light bar 10 comprises a circuit board 11 and a plurality of light emitting diodes 12 on circuit board 11 of being sticked.
Said circuit board 11 is a strip, comprises the first relative long limit 111 and the second long limit 112, and the first relative minor face 113 and second minor face 114.In this embodiment, have two first protruding 111a on the said first long limit 111, on the said second long limit 112 with said two first protruding 111a over against the position on be formed with two first groove 112a.The size of the said first protruding 111a and the first groove 112a is suitable, makes the first protruding 111a of a circuit board 11 can insert in the first groove 112a of another circuit board 11, and realizes interfixing between two circuit boards 11.Have one second protruding 113a on said first minor face 113, on said second minor face 114 with the said second protruding 113a over against the position on be formed with one second groove 114a.The size of the said second protruding 113a and the second groove 114a is suitable, makes the second protruding 113a of a circuit board 11 can be inserted in the second groove 114a of another circuit board 11, and realizes interfixing between two circuit boards 11.The quantity that is appreciated that the first protruding 111a, the first groove 112a, the second protruding 113a and the second groove 114a on the said circuit board 11 should be not limited to this embodiment.In other embodiments, the quantity of the said first protruding 111a and the first groove 112a also can be one, three, four or the like, and the quantity of the said second protruding 113a and the second groove 114a also can be two, three, four or the like.
Please further consult Fig. 3, said circuit board 11 comprises bottom 115, circuit layer 116 and top layer 117.Said circuit layer 116 is between bottom 115 and top layer 117.
Have corresponding with said a plurality of light emitting diode 12 manyly to electrode 116a on the said circuit layer 116, every couple of electrode 116a comprises a positive pole and a negative pole, is used for being electrically connected with a light emitting diode 12.Also have one first electrode wires 116b and one second electrode wires 116c on the said circuit layer 116.But said many to electrode 116a serial or parallel connection between the first electrode wires 116b and the second electrode wires 116c.In this embodiment; Said circuit layer 116 all has electric connection point at the first protruding 111a, the first groove 112a, the second protruding 113a and the second groove 114a place; And circuit layer 116 all is electrically connected with the first electrode wires 116b at the electric connection point at the first protruding 111a and the second protruding 113a place, and circuit layer 116 all is electrically connected with the second electrode wires 116c at the electric connection point of the first groove 112a and the second groove 114a.When the first protruding 111a of a circuit board 11 is inserted among the first groove 112a of another circuit board 11, then can realize the electrical connection between these two circuit boards 11.Same, when the second protruding 113a of a circuit board 11 is inserted among the second groove 114a of another circuit board 11, also can realize the electrical connection between two corresponding circuit boards 11.Among the said first electrode wires 116b and the second electrode wires 116c, one is the positive electricity polar curve, and another is the negative electricity polar curve.
