    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.

The calculator calculates a temporal average of a current flowing through the LEDs based on the voltage data, and generates current data corresponding to the temporal average. The driver drives the first switching element and the second switching element based on the current data.

    摘要: A light source device having light guide elements (2a to 2f) and light emitting elements (3a to 3f) for supplying light to each of the light guide elements. The light guide elements each has a wedge-like shape whose thickness is reduced from one end to the other end. The light guide elements are tandem arranged such that the thinner end of a light guide element lies over the thicker end of the other light guide element. Each light guide element has holding sections recessed in the width direction (8a to 8f, 9a to 9f) in its thicker end on which the other light guide element lies. In the light guide device in which the wedge shaped light guide elements are tandem arranged, positional displacement between light guide elements is prevented.
