Methods and apparatus for providing lighting via a grid system of a suspended ceiling

摘要: Methods and apparatus for providing sources of light, or mechanical and/or electrical connections light sources, via a grid system suspended ceiling. All portion ceiling may be configured to support the generation light. Lighting units coupled various portions in removable modular fashion, so as completely substantially recessed above surface, pendant components hanging below surface. interface also facilitate significant thermal dissipation from lighting units. In one exemplary implementation, more LED-based provide controllable multi-color an/or essentially white
