    摘要: 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.

    摘要: A backlight (illumination device; 2) of the present invention includes: multiple light sources (5); and multiple light guides (7, 17, . . . ) for causing surface emission of light from the light sources (5). Each of the light guides (7, 17, . . . ) includes: a light-emitting section (7b, 17b, . . . ) having a light-emitting surface (7a); and a light guide section (7c) for guiding, to the light-emitting section (7b, 17b, . . . ), light from the light sources (5), a light-emitting section (7b) of a first light guide (7) being provided above a light guide section (17c) of a second light guide (17) adjacent to the first light guide (7). A light amount adjusting section (11) for reducing the amount of light incident on it is provided between the light-emitting section (7b) of the first light guide (7) and the light-emitting section (17b) of the second light guide. This allows for production of an illumination device having further improved luminance uniformity.
