20090269523 | BRAZING ALLOY AND CERAMIC DISCHARGE LAMP EMPLOYING SAME - There is described a brazing alloy having a first component comprising a source of molybdenum and a source of aluminum and a second component comprising boron, wherein a weight ratio of said second component to said first component is not greater than 1:20. The addition of boron results a substantially lower melting point than alloys employing molybdenum and aluminum alone. It is suitable for use in discharge vessels having a hollow bodies selected from the group of monocrystalline alumina, polycrystalline alumina and aluminum nitride; metallic electrode holders fitted into ends of the hollow body; and sealed thereto by a braze. | 10-29-2009 |

20120074835 | LED Wavelength-Coverting Plate with Microlenses in Multiple Layers - A wavelength-converting plate for a wavelength-converted light emitting diode (LED) assembly. The wavelength-converting plate includes multiple layers of microlenses deposited thereon. The microlenses may have an index of refraction different from an index of refraction of the wavelength-converting plate. | 03-29-2012 |
20120261688 | LED WAVELENGTH-CONVERTING STRUCTURE INCLUDING A THIN FILM STRUCTURE - A wavelength-converting structure for a wavelength-converted light emitting diode (LED) assembly. The wavelength-converting structure includes a thin film structure having a non-uniform top surface. The non-uniform top surface is configured increase extraction of light from the top surface of a wavelength-converting structure. | 10-18-2012 |
20120326196 | PHOSPHOR AND LEDS CONTAINING SAME - There is herein described a phosphor for use in LED applications and particularly in phosphor-conversion LEDs (pc-LEDs). The phosphor has a composition represented by (Y | 12-27-2012 |
20130002129 | PHOSPHOR AND LEDS CONTAINING SAME - There is herein described a phosphor for use in white pc-LED applications. The phosphor has a composition represented by (Y | 01-03-2013 |
20130009541 | LED LIGHTING DEVICE HAVING A PHOSPHOR COMPOSITION - There is herein described a phosphor composition for converting the light emitted from LED dies. The phosphor composition has an emission dominant wavelength responsive to an excitation dominant wavelength. The phosphor composition includes a first phosphor, a second phosphor and a third phosphor. The phosphor composition has a first weight ratio of the first phosphor and the second phosphor, and a second weight ratio of the second phosphor and the third phosphor. The first and second weight ratios are arranged so that the emission dominant wavelength increases as the excitation dominant wavelength increases. | 01-10-2013 |
20130250544 | CERAMIC WAVELENGTH-CONVERSION PLATES AND LIGHT SOURCES INCLUDING THE SAME - A wavelength-conversion plate is described herein. The wavelength conversion plate may include a converter of a first ceramic material and a reflector of a second ceramic material. The first ceramic material converts the primary light emitted by a light source such as a light emitting diode (LED) into a secondary light and the second ceramic material reflects the secondary light emitted by said converter. Preferably, the converter is inlaid into the reflector so that the reflector surrounds an outer edge of the converter. Such a configuration has an advantage of reducing unwanted side emissions from the converter. | 09-26-2013 |
