<P>PROBLEM TO BE SOLVED: To provide a light emitting element lamp and a lighting fixture, capable of effectively restraining temperature rise of a substrate on which a light-emitting element is mounted by utilizing a reflector. <P>SOLUTION: The light-emitting element lamp 1 includes 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 an outer peripheral surface exposed outward, a base 4 connected with the reflector 2 through a cover part 3, a thermally conductive heat dissipation member 8 provided on an inner peripheral surface of the reflector 2 and thermally coupled with the reflective surface 2a, a substrate 7 fixed to the heat dissipation member 8 while thermally coupling the substrate surface therewith under a surface contact state and on which a light-emitting element 6 is arranged, a lighting circuit 9 housed in the cover part 3 and lighting the light-emitting element 6, and a translucent cover 5 covering the light irradiation opening 2c of the reflector 2. <P>COPYRIGHT: (C)2009,JPO&INPIT |
