ENAMEL SUBSTRATE FOR MOUNTING LIGHT-EMITTING ELEMENT, LIGHT-EMITTING ELEMENT MODULE, ILLUMINATION DEVICE, DISPLAY DEVICE, AND TRAFFIC SIGNAL

摘要

PROBLEM TO BE SOLVED: To provide an enamel substrate for mounting a light-emitting element which can improve mechanical reliability of a light-emitting module by improving rigidity of a substrate.

SOLUTION: In the enamel substrate for mounting a light-emitting element in which the surface of a core metal is covered with an enamel layer, the aspect ratio of the substrate is not more than 20 times and the thickness of the substrate is not less than 1.0 mm. The light-emitting module is formed so that a light-emitting element is mounted on the enamel substrate for mounting a light-emitting element.
