摘要： Disclosed herein are “smart” phosphor compositions capable of regulating the chromaticity of their emission to substantially constant values even with variations in the excitation radiation they receive to induce photoluminescence. One phosphor of the smart composition demonstrates an increase in emission intensity increases as the wavelength of the excitation radiation is increased. The other phosphor shows a decrease in emission intensity with increasing excitation wavelength. Constant chromaticity in this context is defined as a change in CIE x or y coordinate of less than about five percent over a 10 nm range of excitation wavelengths.

摘要： A high CRI white light emitting device comprises: a blue solid state light emitter (LED) operable to generate blue light; a phosphor material operable to absorb a portion of the blue light and to emit green/yellow light and a red solid state light emitter (LED) operable to generate red light. The emission product of the device comprises the combined light generated by the blue and red LEDs and green/yellow light generated by the phosphor material and appears white in color. The device further comprises a drive circuit operable to compensate for variation in the ratio (relative contribution) of red to blue light in the emission product such as to ensure that said variation is less than 20% over an operating temperature range of at least 25° C. The drive circuit can reduce variation in the CRI and CCT of the device's emission product over the operating temperature range.

摘要： A lighting system for generating an illumination product comprises an excitation source, blue/UV LED, operable to generate excitation radiation and a remotely located phosphor, photo luminescent material. Excitation radiation is guided from the excitation source to the phosphor by a waveguiding medium, the waveguiding medium being configured such that the distance the radiation travels from the excitation source to the phosphor layer is at least one centimeter in length. The UV/blue excitation source provides excitation radiation to the phosphor(s), causing the phosphor(s) to photo luminesce, and it may also provide a component of the final illumination product. The configuration of the waveguide allows a greater flexibility in lighting system configurations, such as hanging lighting fixtures, desk lighting fixtures, floor standing lighting fixtures, desk lamps, track lighting, spot lighting, accent lighting, lighting panels, inspection lamps and endoscopes.
