Abstract
A solid-state light source with LEDs contained in a light recycling cavity emits both light and heat from heat extracting light emitting elements which form the light recycling cavity. Eliminating appended heat sinks makes these light sources ultra lightweight. The light sources can be attached and supported by suspended ceilings without affecting the seismic properties of the ceiling. The heat extracting light emitting elements are combined with a reflector to make directional light sources, which can be attached to ceilings with small magnets. Because the heat extracting light emitting elements transfer the heat from the light source to the illuminated area there is no requirement for disturbing or penetrating the ceiling barrier to a heat sink on the plenum side of the ceiling. This enables a contiguous acoustic ceiling. Further, the light sources are made from non flammable materials and therefore do not affect the fire rating of the ceiling.
