Abstract
A light emitting diode (LED)-based optically indirect luminaire includes a reflector that receives light generated by an LED light source platform and reflects the light beyond the platform into a space to be illuminated. The LED light source platform can be configured as a pendant that is suspended from the reflector by one or more supports or cables. The LED light source platform can include a heat sink that receives the LEDs and the printed circuit board (PCB) they are disposed upon so that the LEDs are visible to the reflector and hidden from view. An optional lens can be included that covers the LEDs and PCB to protect them from dust and moisture.
