20080284313Structured Luminescence Conversion Layer - An apparatus device such as a light source is disclosed which has an OLED device and a structured luminescence conversion layer deposited on the substrate or transparent electrode of said OLED device and on the exterior of said OLED device. The structured luminescence conversion layer contains regions such as color-changing and non-color-changing regions with particular shapes arranged in a particular pattern.11-20-2008
20090261366OPTOELECTRONIC COMPONENT - An optoelectronic component with a semiconductor body that comprises an active semiconductor layer sequence is disclosed, which is suitable for generating electromagnetic radiation of a first wavelength that is emitted from a front face of the semiconductor body. The component also comprises a first wavelength conversion substance following the semiconductor body in its direction of emission, which converts radiation of the first wavelength into radiation of a second wavelength different from the first wavelength, and a first selectively reflecting layer between the active semiconductor layer sequence and the first wavelength conversion substance that selectively reflects radiation of the second wavelength and is transparent to radiation of the first wavelength.10-22-2009
20090272998OPTOELECTRONIC SEMICONDUCTOR CHIP COMPRISING A WAVELENGTH CONVERSION SUBSTANCE, AND OPTOELECTRONIC SEMICONDUCTOR COMPONENT COMPRISING SUCH A SEMICONDUCTOR CHIP, AND METHOD FOR PRODUCING THE OPTOELECTRONIC SEMICONDUCTOR CHIP - A semiconductor chip comprises: a semiconductor body which comprises a semiconductor layer sequence suitable for emitting electromagnetic radiation of a first wavelength range from its front side; and a first wavelength-converting layer on at least one first partial region of the front side of the semiconductor body with a first wavelength conversion substance, which converts radiation of the first wavelength range into radiation of a second wavelength range, which is different from the first wavelength range, wherein at least one second partial region of the front side is free of the first wavelength-converting layer. An optoelectronic component comprising such a semiconductor chip and a method for producing the semiconductor chip are furthermore described.11-05-2009
20100301353LED LIGHTING DEVICE HAVING A CONVERSION REFLECTOR - An LED lighting device is provided which may include at least one light-emitting diode and at least one conversion reflector, wherein the conversion reflector is configured to emit at least a portion of light emitted from the light-emitting diode at a converted wavelength, and wherein the conversion reflector covers the at least one light-emitting diode.12-02-2010

20100291856DEVICE FOR GENERATING AN AIR WALL - A device for generating an air wall comprises a primary blower slit for generating a flat primary air stream in a passage opening mutually separating two spaces with different temperatures. Two adjacent air streams with the same direction and speed are added to the primary air stream. The primary air stream has a temperature between those of the secondary air streams. The absolute humidity of the air of the primary air stream is at least equal to that of the cold secondary air stream and lower than that of the warm secondary air stream. The air speed of the primary air stream amounts to at least 15 m/s. The width of the primary blower slit lies in the range of 15-40 mm. The length of the primary blower slit in the direction of the air stream lies roughly in the range of 5-40 cm, preferably 10-30 cm. No mixing occurs hereby occurs between the primary air stream Sp and the second secondary air stream Ss11-18-2010
