发明名称 Light control device exhibiting batwing luminous intensity distributions in upper and lower hemispheres
摘要 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.
