SUBSTRATE FOR LIGHT EMITTING DIODES

摘要

[Problem] To provide a substrate for light emitting diodes, which is capable of exhibiting high heat dissipation performance by achieving low thermal resistance as a whole substrate without decreasing the insulation reliability and the high-humidity reliability of the substrate. [Solution] A substrate for light emitting diodes, which is provided with a metal base that has a thickness of a predetermined value or more. This substrate for light emitting diodes is configured such that: the thickness of a surface conductor for electrical connection to a light emitting diode (LED) is within a predetermined range; and the thickness of the surface conductor and the thickness of an insulating layer for electrically insulating the metal base and the surface conductor from each other satisfy a predetermined relation.
