[0012] Compared with the prior art, this application has the following beneficial effects:
[0013] 1. The present application adopts a method of arranging two conical protrusions with different inclinations on opposite surfaces on the lens body, and designs an asymmetric narrow-angle polarized outdoor wall washer LED lens, so that the light emitted by the LED lamp can be emitted to the bottom of the illuminated wall, solving the problem that the conventional LED lens cannot effectively control the light beam to the bottom of the illuminated wall, which will illuminate the bottom dark area and affect the lighting effect.
