LIGHT CONTROL DEVICE EXHIBITING BATWING LUMINOUS INTENSITY DISTRIBUTIONS IN UPPER AND LOWER HEMISPHERES

摘要

A light control device implemented as a luminaire (10) exhibits an ultra-widebatwing luminous intensity distributionin an upper hemisphere (102) that provides substantially uniform illuminationof a ceiling surface (44), even when the luminaire ismounted very close to the ceiling. Luminous side panel diffusers (78, 80)facilitate blending the luminaire with the ceiling surfaceas they create a batwing luminous intensity distribution in a lower hemisphere(100) to evenly illuminate a work plane (104).
