Abstract:
A light guide system (20) for controlling out-coupling of light is provided. The light guide system comprises a light guide (21) configured to receive ambient light from at least one light source (26), and emit spread ambient light from a surface thereon. The light guide system further comprises a reflector (22) provided with a number of protrusions (23). In use, the reflector (22) and the light guide (21) are attached together. An advantage of this embodiment is that a uniform light -radiating surface using a light guide is enabled.
