LIGHT-EMITTING UNIT, ILLUMINATING DEVICE USING SUCH LIGHT-EMITTING UNIT, AND IMAGE SCANNER

摘要

Disclosed is a light-emitting unit for illuminating devices which is excellent in heat dissipation performance. Specifically disclosed is a light-emitting unit comprising a light-emitting element, a light-emitting element substrate for mounting the light-emitting element, a light-emitting element substrate frame having an open window for exposing the light-emitting element, and an electrode for feeding electricity to the light-emitting element. This light-emitting unit is characterized in that the light-emitting element substrate is made of a metal and the light-emitting element is directly mounted on the light-emitting element substrate. The light-emitting unit is alternatively characterized in that the light-emitting element substrate is made of a metal, a metal oxide film is formed on the light-emitting element substrate, and the light-emitting element is mounted on an electrode formed on the metal oxide film.
