20100271565 | ILLUMINATION DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE - An illumination device includes an LED package, an LED driver including an FET, and a thermistor disposed on a substrate. A plurality of such LED packages are disposed on the substrate such that a first area and a second area, each determined by vertices corresponding to LED packages, are defined on the substrate. The thermistor is disposed in the first area, and the FET is disposed in the second area, which is outside of the first area. The thermistor detects a temperature in the first area. Such a configuration allows the thermistor to detect, in accordance with the temperature in the area, the temperature of heat transferred from the LED packages, without being affected by heat generated by the FET. This makes it possible to efficiently make temperature corrections to stabilize color temperature and luminance. | 10-28-2010 |
20110013393 | SURFACE-EMISSION UNIT AND METHOD FOR PRODUCING THE SAME - A surface-emission unit to prevent irregularity in brightness from being generated is provided. The surface-emission unit is composed of light-emission element parts each having a light-emission element, aligned and arranged on a substrate two-dimensionally, and optical lenses each arranged on the substrate with respect to each light-emission element part, to diffuse light from the light-emission element, and a support part to fix the optical lens onto the substrate is arranged so as not overlap a line connecting the light-emission element part corresponding to the optical lens fixed by the support part, to another light-emission element part adjacent to the light-emission element part. | 01-20-2011 |
