20090010017 | LIGHT EMITTING DEVICE - A light emitting device comprises; a metal reflecting member, a light emitting element fixed to the metal reflecting member, a glass film that covers the metal reflecting member and has Si—N bonds, and a translucent resin that covers the glass film. The present invention provides a light emitting device with which, even when this device is used in a harsh environment, there will be no deterioration in the light reflecting performance of the metal reflecting member, and light can be emitted at high output over an extended period. | 01-08-2009 |
20090072700 | PHOSPHOR-CONTAINING MOLDED MEMBER, METHOD OF MANUFACTURING THE SAME, AND LIGHT EMITTING DEVICE HAVING THE SAME - In a method of manufacturing a phosphor-containing molded member, an inorganic powder in a mixture with a phosphor powder is melted by using Spark Plasma Sintering method, and then cooled. In a phosphor-containing molded member, a content of the phosphor therein is 5% by weight or more. | 03-19-2009 |
20100301738 | PHOSPHOR, LIGHT EMITTING DEVICE USING THE SAME AND METHOD OF MANUFACTURING THE PHOSPHOR - Provided are a phosphor which is capable of emitting green light of high luminance and in which unfavorable effects on other members has been reduced so as to be applicable to white light having excellent light emitting characteristics, a light emitting device using the phosphor, and a method for manufacturing the phosphor. The phosphor containing silicon, magnesium, and chlorine, and activated with europium and capable of emitting green light, in which the molar ratio of chlorine to magnesium is in a range of 1.0≦Cl/Mg≦1.9. Introduction of chlorine at such a composition ratio improves the light emitting characteristics and the amount of chlorine dissolved. | 12-02-2010 |
20110031874 | LIGHT EMITTING APPARATUS - A red nitride phosphor of formula (I) or (II), and two green phosphors of formulas (III) and/or (IV) are included. | 02-10-2011 |
20140319568 | PHOSPHOR, LIGHT-EMITTING APPARATUS INCLUDING THE SAME, AND PHOSPHOR PRODUCTION METHOD - A phosphor is provided which is represented by the general formula M | 10-30-2014 |
20140321099 | PHOSPHOR, LIGHT-EMITTING APPARATUS INCLUDING THE SAME, AND PHOSPHOR PRODUCTION METHOD - A phosphor is provided which is represented by the general formula M | 10-30-2014 |
20150084083 | PHOSPHOR, PRODUCTION METHOD OF THE PHOSPHOR, AND LIGHT EMITTING DEVICE USING THE PHOSPHOR - A phosphor is provided which includes a general formula represented by Ca | 03-26-2015 |
20150214444 | PHOSPHOR AND LIGHT EMITTING DEVICE USING THE SAME - A phosphor for absorbing light in a region from ultraviolet to visible light and emitting light whose emission peak wavelength being in a range of 600 nm to 650 nm, represented by general formula shown below, and having a difference between the emission peak wavelength and a half width being larger than 543 nm. | 07-30-2015 |
