| 20090061723 | METHOD AND APPARATUS FOR SEALING FLUORESCENT LAMP - A method for sealing a fluorescent lamp performs a first heating operation to heat a region of a glass tube in which a fluorescent material is coated, stretches the glass tube at the heated region, and performs a second heating operation to heat the stretched region of the glass tube. | 03-05-2009 |
| 20100003884 | Conductive Composition and Applications Thereof - A conductive composition and applications thereof are provided. The conductive composition comprises a mixture consisting of a metal powder and a glass powder. The diameter of the metal powder ranges from about 1 μm to about 3 μm. The diameter of glass powder ranges from about 0.5 μm to about 1 μm. The weight percentage of the metal powder to the mixture is from about 60% to about 98%.

| 20100029166 | FABRICATION METHOD OF DISCHARGE LAMP - A fabrication method for discharge lamps is disclosed, which comprises providing a glass tube of diameter between 2 and 20 mm, the glass tube having an inner wall coated with a fluorescent phosphor and having a through-passage with a first end and a second end, connecting a first dielectric electrode to the first end of the glass tube by applying an adhesive to a contacted portion of the glass tube and the first dielectric electrode, and sintering the contacted portion of the glass tube and the first dielectric electrode to securely connect the glass tube and the first dielectric electrode. Subsequently, processes of filling and sealing are conducted to complete the fabrication of the discharge lamps. | 02-04-2010 |
| 20100130092 | AMALGAM SPHERES FOR ENERGY-SAVING LAMPS AND THE MANUFACTURE THEREOF - Energy-saving lamps contain a gas filling of mercury vapour and argon in a gas discharge bulb. Amalgam spheres are used for filling the gas discharge bulb with mercury. A tin amalgam having a high proportion by weight of mercury in the range from 30 to 70% by weight is proposed. Owing to the high mercury content, the amalgam spheres have liquid amalgam phases on the surface. Coating of the spheres with a tin or tin alloy powder converts the liquid amalgam phases on the surface into a solid amalgam having a high tin content. This prevents conglutination of the amalgam spheres during storage and processing. | 05-27-2010 |
| 20110039472 | METHOD OF MANUFACTURING A LAMP - Disclosed is a method of manufacturing a lamp. The lamp is formed by arranging lamp electrodes in a lamp body provided therein with a discharge space and a fluorescent material. A first conductive layer is formed on a base conductor and a second conductive layer is formed on the first conductive layer by allowing the first conductive layer to react with a reaction solution including a solvent and metallic salt, thereby forming the lamp electrodes. | 02-17-2011 |
| 20110117805 | METHOD FOR MANUFACTURING HIGH PRESSURE DISCHARGE LAMP - Provided is a manufacturing method to prevent devitrification of a bulb in a high pressure discharge lamp used for a projector. The method is for manufacturing a high pressure discharge lamp which uses, as a light source, a bulb made of fused quartz and including a tungsten electrode, and which is horizontally installed when the lamp is driven for actual use. The method includes the step of initially driving the bulb with an optical axis thereof being set horizontally before the high pressure discharge lamp is shipped. In the initial driving step, the rotation angle around the optical axis of the bulb is offset by 45° or more and 135° or less relative to the rotation angle around the optical axis of the bulb when the lamp is driven for actual use. | 05-19-2011 |
| 20110171872 | METHOD FOR MANUFACTURING AN EXTERNAL ELECTRODE FLUORESCENT LAMP - An external electrode fluorescent lamp includes a glass tube made of soft glass, and external electrodes affixed to outer surfaces of both ends of the glass tube. The fluorescent lamp further includes a joining material applied between at least the glass tube and the external electrodes for affixing the external electrodes, which are made up of a material having a thermal expansion coefficient that is larger than that of the glass tube. According to the manufacturing method of the fluorescent lamp, first, the external electrodes are attached to the outer surface of each end of the glass tube, the external electrodes are then immersed in fused solder, and finally, the glass tube is cooled to room temperature. In this manner, the external electrodes are affixed to the outer surface of the glass tube via soldering. | 07-14-2011 |
