LIGHT SOURCE MODULE, LAMP, AND LUMINAIRE

摘要

PROBLEM TO BE SOLVED: To provide a light source module, a lamp, and a luminaire such that the light source module which employs a ceramic substrate prevents a solder part between the ceramic substrate and a contact for electric power supply from cracking.SOLUTION: A lamp 3 includes: a module substrate 22 as a ceramic substrate which is mounted with a light emission part 22B and provided with a plurality of wiring patterns 31 connected to the light emission part 22B, and has insulation properties; a plurality of contacts 32 which each have one end connected to a power supply part and supply electric power to the light emission part 22B; a support member 34 which supports the plurality of contacts 32; solder 33 which fix the another end of each of the plurality of contacts 32 to the module substrate and also electrically connects the another end to one of the plurality of wiring patterns 31; and solder 36 which fixes the support member 34 to the module substrate 22.
