摘要:
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.
摘要:
Reflector designs for a large area panel light source create induced draft cooling means adjacent to the panel light source. The panel light source has a wavelength conversion element on a solid state light source for emitting light of a first and second wavelength to form a broader emission spectrum of light from the panel light source.
摘要:
Solid state light sources based on LEDs mounted on or within thermally conductive luminescent elements provide both convective and radiative cooling. Low cost self-cooling solid state light sources can integrate the electrical interconnect of the LEDs and other semiconductor devices. The thermally conductive luminescent element can completely or partially eliminate the need for any additional heatsinking means by efficiently transferring and spreading out the heat generated in LED and luminescent element itself over an area sufficiently large enough such that convective and radiative means can be used to cool the device.

Thin freestanding nitride veneers can be used for the fabrication of semiconductor devices. These veneers are typically less than 100 microns thick. The use of thin veneers also eliminates the need for subsequent wafer thinning for improved thermal performance and 3D packaging.

摘要:
A solid state light source with LEDs in thermal contact to thermally conductive translucent elements where light emitted from the LEDs is directed to emerge from the heat dissipating surfaces of the elements. The thermally conductive translucent elements are arranged or combined with a reflector to form a light recycling cavity. The outside surfaces of the thermally conductive translucent elements forming the cavity become luminescent as the light emitted by the LEDs on the inside of the cavity is continually reflected and recycled until a very high percentage of the light emitted by the LEDs is eventually transmitted through and emitted uniformly and omnidirectionally. Simultaneously, the heat from the LEDs conducts through and to the luminescent outside surfaces of the elements of the cavity, which radiatively and convectively cool the light source thereby eliminating the need for bulky appended heat sinks.

摘要:
A self-cooling emitter is a light emitting element embedded within a thermally conductive luminescent element which functions as a thermal cooling means and wavelength conversion of the light emitting element. The thermally conductive luminescent element exhibits a bulk thermal conductivity greater than 1 W/m/K such that there is sufficient thermal spreading of the heat generated by the light emitting element.

摘要:
A wavelength conversion chip is formed by depositing a wavelength conversion material on a substrate to form a layer, removing the resulting wavelength conversion layer from the substrate and then segmenting the wavelength conversion layer into a plurality of wavelength conversion chips. The wavelength conversion material can be annealed by thermal annealing or radiation annealing to increase the wavelength conversion efficiency of the chips or to sinter the wavelength conversion material to form a ceramic material. Optical coatings, vias, light extraction elements, electrical connections or electrical bond pads can be fabricated on the wavelength conversion chips.
