A light source 13 is generally arranged in the lamp, a light-incoming side 25 is arranged on one side of the grating 20 facing the light source 13, and a light-outgoing side 26 is arranged on one side of the grating 20 away from the light source 13; the light generated by the light source 13 is transmitted from the light-incident side 25 to the light-exiting side 26 via the grating holes 22.

When light generated inside the lamp irradiates on the grating 20, the light is reflected by the grating 20 in a parallel state and is concentrated to be reflected towards a specific direction outside the lamp, so that the glare problem exists outside the lamp.
