Further, the number of the arc-shaped surfaces is 200 to 250, so that light rays emitted by the LED light source can obtain larger light diffusion when passing through the light-gathering cup, and the glare value is further reduced.

Further, the function of the reflecting film is to process the light emitted by the arc-shaped surface.

Further, the light absorption ring is used for processing the light which does not enter the light condensation cup from the LED light source, so that the glare value is further reduced.

Further, the included angle between the panel and the reflective film is 36 degrees.

Furthermore, the material of the reflecting cup and the PC lens is polycarbonate, and the forming process is injection molding once.

In conclusion, the beneficial effects of the utility model are that: the back of the PC lens is provided with a buckling position which directly connects the PCB, the reflecting cup and the PC lens into a whole without additional screw fixation, so that the whole installation is convenient and the installation efficiency is high, meanwhile, the fixed relation of the lamp assembly is not required to be considered when the LED lamp is designed, the lamp assembly is higher in universality, and the LED lamp is suitable for batch production and use.
