SEMICONDUCTOR CHIP FOR DRIVING LIGHT EMITTING ELEMENT, LIGHT EMITTING DEVICE AND LIGHTING EQUIPMENT

WIPO Patent Application WO/2005/104249

A1

A light emitting device is provided to correctly detect a temperature of a light emitting element and to prevent breakage and deterioration of the light emitting element. The light emitting device is provided with an electric signal terminal, a light emitting element, which is driven by an electric signal given to the electric signal terminal from the external, and a semiconductor chip for driving the light emitting element. In the semiconductor chip, a circuit for driving the light emitting element for outputting the electric signal and applying it to the electric signal terminal, and a temperature detecting element for detecting an ambient temperature are formed of a semiconductor. The light emitting element is mounted on a plane of the semiconductor chip and is driven, being associated with a temperature detected by the temperature detecting element.
