Abstract

The utility model discloses an LED (light-emitting diode) lamp with high light transmission, which comprises an aluminum pipe, an LED lamp panel, a PC (polycarbonate) pipe and a powder diffusing layer, wherein the PC pipe is fixedly connected with the aluminum pipe, the surface of the PC pipe is a fine wire drawing surface, the powder diffusing layer is arranged on the wire drawing surface of the PC pipe in a covering manner, and the light emitting surface of the LED lamp panel is arranged towards the fine wire drawing surface of the PC pipe and the powder diffusing layer. The LED lamp has the following beneficial effects: as the common PC pipe is replaced by the PC pipe with the fine wire drawing surface and the powder diffusing layer for refraction, the LED lamp has good light transmitting and scattering effects and good light emitting angle. The sticking encapsulation of a silica gel layer is replaced by the fixing of a clamping groove, so that the fixing effect is good and the cost of the silica gel layer is saved.
