Light emitting element lamp and lighting equipment |
摘要 |
An object of the present invention is to provide a light emitting element lamp and a lighting equipment effectively suppressing a temperature rising of a substrate on which a light emitting element is mounted by using a reflector. The present invention provides a light emitting element lamp 1 including: a heat-conductive reflector 2 having an emission opening portion and formed to be widened toward the emission opening portion with a reflecting surface 2a being provided on an inner surface side and an outer peripheral surface being exposed to an outside; a base 4 connected to the reflector 2 via a cover 3; a heat-conductive heat radiating member 8 provided on an inner peripheral surface of the reflector 2 and thermally connected to the reflector 2; a substrate 7 having a light emitting element 6 mounted thereon and attached to the heat radiating member 8 with a substrate surface being thermally connected to the heat radiating member 8 in a surface contact state; a lighting circuit 9 housed in the cover 3 to light the light emitting element 6; and a translucent cover 5 for covering the emission opening portion 2c of the reflector 2.
