| 20120056539 | Vehicle Discharge Lamp, Vehicle Discharge Lamp Device, Lighting Circuit Combined Type Vehicle Discharge Lamp Device, and Lighting Circuit - Provided is a mercury-free vehicle discharge lamp that is stably lighted with a power of 18 to 30 W in a steady time. The lamp is defined in a light-emitting portion ( | 03-08-2012 |
| 20110096544 | ILLUMINATION DEVICE - Provided is an illumination device which is designed to have increased brightness, to provide a uniform light distribution, and to provide a thinner form to an illumination device employing an LED light source, and is equipped with direct illumination and indirect illumination functions. In the illumination device, a hollow light guide region ( | 04-28-2011 |
| 20100109528 | FOIL SEALED LAMP - A foil sealed lamp including an airtight container including a discharge portion provided thereinside with a discharge space and seal parts disposed at both ends of the discharge portion; metal foils of thickness T (μm) hermetically attached to the seal portions; a pair of electrodes each having its one end connected to the metal foil and having its other end led out to the discharge space; and on the periphery of areas of connection of the metal foils with the pair of electrodes, multiple recessed portions satisfying 1.0 (μm)≦D≦T (μm) wherein D refers to the depth (μm), in a manner that the recessed portions do not overlap one another. | 05-06-2010 |
| 20100060172 | Hollow Planar Illuminating Apparatus - A light reflection surface member ( | 03-11-2010 |
| 20100059767 | Surface Light-Emitting Device and Display Device Using the Same - A surface light-emitting device is disclosed, in which a plurality of spot light sources are arranged along the side surface of a housing of the device, and the light emitted from the spot light sources located at the end portions of the spot light source sequence emits a lower light flux than the average light flux of the light emitted from the other spot light sources. The spot light source sequence is, for example, an LED array including an alignment of light-emitting diodes (LEDs). The LED array includes two groups of LED elements arranged in a predetermined repetitive pattern from one and the other ends, respectively, of the LED array, and at least an LED emitting low light flux is arranged at a predetermined position in the vicinity of the center of the array. As a result, the requirement for a reduced thickness and a narrower frame can be met, while at the same time producing the white light of uniform chromaticity over the whole light-emitting surface. | 03-11-2010 |
| 20090289566 | Lighting Device for a Discharge Lamp - The lighting device for a discharge lamp includes a bridge type rectifying and converting circuit CR | 11-26-2009 |
| 20090253334 | Method for Manufacturing an Electric Bulb - In an electric bulb wherein a pair of lead-in wires | 10-08-2009 |
| 20090253330 | Low-Pressure Discharge Lamp And Method For Manufacturing Thereof - A low-pressure discharge lamp having a tubular glass lamp vessel | 10-08-2009 |
| 20090129070 | METAL HALIDE LAMP AND LIGHTING DEVICE USING THEREWITH - A metal halide lamp comprises a translucent air tight vessel ( | 05-21-2009 |
| 20090052163 | BACK LIGHT DEVICE - In a back light device | 02-26-2009 |
| 20090046220 | BACKLIGHT FOR LIQUID CRYSTAL DISPLAY DEVICE - A backlight for a liquid crystal display device includes a plurality of point light sources | 02-19-2009 |
