摘要:
In accordance with certain embodiments, illumination systems are formed by aligning light-emitting elements with optical elements and/or disposing light-conversion materials on the light-emitting elements, as well as by providing electrical connectivity to the light-emitting elements
摘要:
In accordance with certain embodiments, an unpackaged inorganic LED die is adhered directly to a yielding substrate with a pressure-activated adhesive notwithstanding any nonplanarity of the surface of the unpackaged inorganic LED die or non-coplanarity of the contacts thereof.
摘要:
A light emitting assembly comprising a solid state device coupleable with a power supply constructed and arranged to power the solid state device to emit from the solid state device a first, relatively shorter wavelength radiation, and a down-converting luminophoric medium arranged in receiving relationship to said first, relatively shorter wavelength radiation, and which in exposure to said first, relatively shorter wavelength radiation, is excited to responsively emit second, relatively longer wavelength radiation. In a specific embodiment, monochromatic blue or UV light output from a light-emitting diode is down-converted to white light by packaging the diode with fluorescent organic and/or inorganic fluorescers and phosphors in a polymeric matrix.
