摘要： Disclosed herein are cerium doped, garnet phosphors emitting in the yellow region of the spectrum, and having the general formula (Y,A)3(Al,B)5(O,C)12:Ce3+, where A is Tb, Gd, Sm, La, Sr, Ba, Ca, and/or Mg, and substitutes for Y, B is Si, Ge, B, P, and/or Ga, and substitutes for Al, and C is F, Cl, N, and/or S, where C substitutes for O. Relative to a solid-state-reaction method, the instant co-precipitation methods provide a more homogeneous mixing environment to enhance the distribution of the Ce3+ activator in the YAG matrix. Such a uniform distribution has the benefit of an increased emission intensity. The primary particle size of the as-prepared phosphor is about 200 nm, with a narrow distribution.

摘要： A semiconductor color image sensor comprises: an array of semiconductor photo-sensors (CMOS or CCD) and a color filter array comprising an array of red, green and blue filter elements in which each filter element is associated with a respective one of the photo-sensors. The sensor further comprises a phosphor (photo-luminescent) material associated with each of the blue filter elements and configured to absorb blue light and re-emit light of a longer wavelength range which is then incident on the photo-sensor associated with the blue filter element. Preferably the phosphor material is selected such that light of the longer wavelength range substantially matches the spectral response of the photo-sensor. The image sensor can further comprise an array of micro-lenses for focusing light onto the photo-sensors of the image sensor, wherein each micro-lens is associated with a respective one of the photo-sensors.

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.

摘要： An LED lighting device comprises: a thermally conducting body having an at least one opening that connects with a cavity within the body and a plurality of LEDs mounted in thermal communication with a face of the body and positioned around the opening. One or more passages pass through the body from the cavity to an outer surface of the body and are configured such that in operation air moves through the cavity by thermal convection thereby to provide cooling of the body. Each passage is configured in a direction that extends in a direction at an angle of about 45° to a line that is parallel with the axis of the body toward the outer surface of the body away from the face. The body can be configured such that its outer surface has a form factor resembling an incandescent light bulb or halogen reflector lamp.
