Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A light emitting device, comprising: an array of LEDs, wherein each LED is configured to emit blue light; and luminophoric medium configured to interact with emitted blue light from the LEDs in said array to produce down-converted light, wherein the luminophoric medium includes red emissive and yellow emissive species and the emitted blue light from the LEDs in said array and the down-converted light produce a white light output, wherein the array of LED…
