Patent application numberDescriptionPublished
20090018622BODY COVER, GLASSES AND/OR AT LEAST PARTIAL HEAD COVER, METHOD FOR RADIATING AT LEAST PART OF A HUMAN BODY AND USE OF A BODY COVER - Body cover, comprising a substrate, for covering at least part of a human body, and at least one electroluminescent source coupled to the substrate, for illuminating at least a part of the body, wherein the cover is configured to at least partly surround at least a part of the body and/or a body support. Method for radiating at least part of a human body, especially in the treatment of jaundice and/or crigler najjar, comprising covering at least part of the body and/or a body support with a cover with at least one electroluminescent source and emitting light from the electroluminescent source to at least part of the body.01-15-2009
20090030489BODY COVER, GLASSES AND/OR AT LEAST PARTIAL HEAD COVER, METHOD FOR RADIATING AT LEAST PART OF A HUMAN BODY AND USE OF A BODY COVER - Body cover, comprising a substrate, for covering at least part of a human body, and at least one electroluminescent source coupled to the substrate, for illuminating at least a part of the body, wherein the cover is configured to at least partly surround at least a part of the body and/or a body support. Method for radiating at least part of a human body, especially in the treatment of jaundice and/or crigler najjar, comprising covering at least part of the body and/or a body support with a cover with at least one electroluminescent source and emitting light from the electroluminescent source to at least part of the body.01-29-2009
20090206301INORGANIC PHOSPHOR BODIES FOR LIGHT EMITTING DIODES - An inorganic phosphor body (08-20-2009
20100246626SIDE-EMITTING LED LIGHT SOURCE FOR BACKLIGHTING APPLICATIONS - This invention relates to a side-emitting light device comprising two sub-assemblies which are optically bonded together. Each sub-assembly comprises a substrate, at least one light source disposed on the substrate, and a luminescent plate optically bonded with the at least one light source. The light source emits light of a wavelength capable of exciting luminescence light from the luminescent plate. The two sub-assemblies are arranged having the free surface of the luminescent plates facing each other. The side-emitting light device is for instance applicable for light sources comprising naked dies arranged with Thin Film Flip Chip (TFFC) technique or laser diodes.09-30-2010
20100315604ILLUMINATION SYSTEM, METHOD AND PROJECTION DEVICE FOR CONTROLLING LIGHT EMITTED DURING A SPOKE TIME PERIOD - The invention relates to an illumination system (12-16-2010
20110084302WAVELENGTH CONVERTED LIGHT EMITTING DIODE WITH REDUCED EMISSION OF UNCONVERTED LIGHT - A method for the manufacture of a wavelength converted light emitting device is provided. A light curable coating material is arranged on the outer surface of a wavelength converted light emitting diode. The light curable coating material is cured, in positions where a high intensity of unconverted LED-light encounters the curable coating material. The method can be used to selectively stop unconverted light from exiting the device, leading to a wavelength converted LED essentially only emitting converted light.04-14-2011
20110095328CLOSE PROXIMITY COLLIMATOR FOR LED - A method for the manufacture of a light emitting device is provided. The method comprises the steps of: providing a substrate (04-28-2011
20110181173PHOSPHOR IN POLYCRYSTALLINE CERAMIC STRUCTURE AND A LIGHT-EMITTING ELEMENT COMPRISNG SAME - The invention relates to a phosphor in a polycrystalline ceramic structure and a light-emitting element provided with the same comprising a Light-Emitting Diode (LED) in which a composite structure of phosphor particles is embedded in a matrix, characterized in that the matrix is a ceramic composite structure comprising a polycrystalline ceramic alumina material, hereafter called luminescent ceramic matrix composite. This luminescent ceramic matrix composite can be made by the steps of converting a powder mixture of ceramic phosphor particles and alumina particles into a slurry, shaping the slurry into a compact, and applying a thermal treatment, optionally in combination with hot isostatic pressing into a polycrystalline phosphor-containing ceramic alumina composite structure. The luminescent ceramic matrix composite further allows a method of tuning the light-diffusing properties by changing at least one of the fractions of phosphor particles and second ceramic particles, the grain size of the particles of the ceramic composite structure, the difference in the refractive index of the particles of the ceramic composite structure, and the porosity in the polycrystalline phosphor-containing ceramic composite structure.07-28-2011
