OPTICAL MODULE AND LAMP

摘要

A lamp includes a frame, a light guide plate, a light source and a reflecting structure. The light guide plate is disposed on the frame and includes a light-incident surface, a first light-emitting surface and a second light-emitting surface. The second light-emitting surface is opposite to the first light-emitting surface, in which the light-incident surface connects the first light-emitting surface and the second light-emitting surface. The light source is adjacent to the light-incident surface and the light source is disposed in the frame. The reflecting structure is adjacent to the first light-emitting surface and includes at least two transparent sheets. The two transparent sheets are separated by an air gap, such that at least one light beam emitted from the first light-emitting surface is reflected back to the light guide plate and is emitted out from the second light-emitting surface.
