LIGHT EMITTING ELEMENT LAMP AND LIGHTING EQUIPMENT

摘要

A light emitting element lamp which can control temperature rise of a substrate on which a light emitting element is arranged effectively by utilizing a reflector. Lighting equipment is also provided. The light emitting element lamp (1) comprises a thermally conductive reflector (2) having an irradiation opening and formed to be enlarged toward the irradiation opening and provided with a reflective surface (2a) on the inner surface side with the outer circumferential surface being exposed outward, a base (4) connected with the reflector (2) through a cover portion (3), a thermally conductive heat radiation member (8) provided on the inner circumferential surface of the reflector (2) and coupled thermally with reflective surface (2a), a substrate (7) fixed to the heat radiation member (8) while thermally coupling the substrate surface therewith under surface contact state and on which a light emitting element (6) is arranged, a lighting circuit (9) accommodated in the cover portion (3) and lighting the light emitting element (6), and a translucent cover (5) covering the light irradiation opening (2c) of the reflector (2).
