Lighting structure having variable transmissivity internal light guide illumination |
摘要 |
A hollow lighting structure having an optically transmissive light emitting surface. At least one light guide extends within the structure. A light source emits light into the light guide. The light guide's light transmissivity is varied as a function of position on the surface of the light guide such that the angular and spatial distribution of light emitted from the light guide yields a predetermined distribution of light intensity as a function of position on the light emitting surface. The predetermined distribution of light intensity is preferably substantially uniform at all points on the light emitting surface.
