20080285267 | LIGHT CONTROL DEVICE EXHIBITING BATWING LUMINOUS INTENSITY DISTRIBUTIONS IN UPPER AND LOWER HEMISPHERES - A light control device implemented as a luminaire exhibits an ultra-wide batwing luminous intensity distribution in an upper hemisphere that provides substantially uniform illumination of a ceiling surface, even when the luminaire is mounted very close to the ceiling. Luminous side panel diffusers facilitate blending the luminaire with the ceiling surface as they create a batwing luminous intensity distribution in a lower hemisphere to evenly illuminate a work plane. | 11-20-2008 |
