LIGHT EMITTING ASSEMBLY WITH SUPPORT FOR HEAT DISSIPATION

摘要

PROBLEM TO BE SOLVED: To provide a light emitting assembly which has an effective technology for dissipating heat and for reflecting light from a light emitting element.

SOLUTION: The light emitting assembly includes a metal substrate for dissipating heat from an assembly. The metal substrate includes an electric insulating layer or a coating at least on its one surface. A line trace is used for an electric insulating layer using a thin or thick film technology. At least the edge of the line trace includes a metal part on which a lead of a light emitting element is soldered or wire bonded. The metal part is placed adjacent to the light emitting element to conduct heat to a base substrate, and/or reflect light from an element being separated from the substrate. The tarnish of the reflecting metal part is delayed by use of clear finishing.
