Abstract
An integrated barrier or partition (e.g. suspended ceiling, wall, etc.) containing lightweight solid state light sources wherein the light emitting surface of the light sources are the primary heat dissipating surfaces of the light sources. The light sources consisting of light emitting diodes (LED) in thermal contact to light transmitting thermally conductive elements and combined with a reflector element to form a light recycling cavity, provide both convective and radiative cooling from their light emitting surfaces, eliminating the need for external appended heat sinks. Seismically safe suspended ceilings contain integrated lighting where the lighting adds less than one gram per square foot to the structure. The lighting, integrated into but without penetrating the barrier (suspended ceiling, ceiling, wall, floor, etc.), is nonflammable and does not promote flame spread or smoke generation. The lighting is easily incorporated into ceiling tiles, sheetrock, grid elements, painted and/or wallpapered surfaces.
