Further, the aperture of described depression site is 0.15mm～0.40mm, and the spacing between described depression site is successively decreased in 0.90mm～0.68mm scope gradually from the end to end of described LGP.

Further, described depression site is the sphere blind hole that laser-induced thermal etching forms.

Further, described flat lamp also includes snap close piece, and described snap close piece is metal clips, the one end is provided with U-shaped section, and the back side of described front frame is provided with draw-in groove, during assembling, described U-shaped section is stuck in described draw-in groove, and the other end of described snap close piece compresses on the described base plate in ground.

Further, described front frame and base plate all adopt aluminum material to be made.

The beneficial effects of the utility model are:

The utility model passes through technique scheme, the LGP arranged has improved light efficiency greatly, end that only need be less at its network point distribution arranging density that caves in arranges LED lamp bar can make the brightness of this one-way light guide flat lamp even, the light efficiency conversion ratio that has truly solved the LED planar lamp is on the low side, non-uniform light, light-emitting area has dark space, the critical defect that bright border etc. is arranged, greatly reduce energy consumption, energy-conserving and environment-protective, and LGP is simple in structure, can not drop in the depression site yet, product quality and performances are secure, stable performance, cost is low, and stripper plate cuts process and can not produce any dust, pollution-free, environmental sanitation is secure.

In addition, front frame and base plate are joined together firmly by snap close piece, without using any instrument, assemble and keep in repair light, convenient, fast, and efficiency is high.
