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.

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.

摘要:
An inner lead and an outer lead are formed only on an insulating tape. A semiconductor chip and the inner lead are connected by the flip chip method by providing an anisotropic conductive material therebetween. A radiating plate is bonded to the insulating tape with use of an adhesive so that the radiating plate covers all regions where solder balls connected with the outer leads are formed. Unlike the TAB type, the inner lead is not uncovered with the insulating tape, whereby deformation of the inner lead is suppressed as much as possible. With this arrangement, the following effect can be achieved. Namely, in a semiconductor device of the BGA type, heat generated during package manufacture can be efficiently emitted, and hence package defects caused by heat and stress during manufacture can be suppressed. As a result, smaller and thinner packages can be manufactured, while pitch narrowing and multiple-port structure can be achieved.
