Detailed description of the invention
Below in conjunction with Fig. 1 to Fig. 3, and detailed description of the invention is described further the utility model.
Implement: 1: see Fig. 1 to Fig. 3.
A kind of backlight module being convenient to assemble, comprise light guide plate 4 and the LED module being arranged at light guide plate 4 side, described LED module comprises pcb board 3 and lens board 2, pcb board 3 is arranged and is arranged at intervals with multiple LED31, described lens board 2 is between pcb board 3 and light guide plate 4, its lens board 2 is provided with the lens curved surface structure 21 of multiple divergence of beam near the side of pcb board 3, lens curved surface structure 21 and LED31 one_to_one corresponding are arranged.
Lens of the prior art are integrated on a lens board 2 by the technical program, substitute divergent lens by lens curved surface structure 21; Therefore in processing, lens board 2 is more simple and convenient, at fit on, only needs lens board 2 to locate fixing, just can by LED31 and lens curved surface structure 21 one_to_one corresponding, and assembling is simple.Spot light is become area source by lens curved surface structure simultaneously, reduces light leak.
