PORCELAIN ENAMELED SUBSTRATE FOR MOUNTING LIGHT-EMITTING DEVICE, LIGHT-EMITTING DEVICE MODULE, LIGHTING SYSTEM, DISPLAY DEVICE, AND TRAFFIC SIGNAL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a porcelain enameled substrate for mounting light-emitting devices which is excellent in heat dissipation; a light-emitting device module in which light-emitting devices are mounted on the substrate; and a lighting system, a display device, and a traffic signal device comprising the light-emitting device module.

SOLUTION: The porcelain enameled substrate for mounting light-emitting devices is constituted by a porcelain enameled substrate 10 which is made by covering the surface of a core metal 12 with a porcelain enameled layer 13, and in which one or more through-holes 19 for heat dissipation are provided. The core metal 12 is exposed on the inner surfaces of the through-holes 19 for heat dissipation. The light-emitting device module 11 is constituted by mounting light-emitting devices on the porcelain enameled substrate for mounting light-emitting devices.
