To provide a lighting fixture which effectively utilizes an installation frame, promotes heat radiation from the front side and the rear side of a light-emitting module, and effectively controls temperature rise of a light-emitting element.
The lighting fixture 1 includes a light-emitting module 2 which has a light-emitting element as a light source and has a light emitting part 23 from which light from the light source is emitted, and in which at least a part of an outer shell 21 has thermal conductivity and is thermally coupled with the light-emitting element, a heat sink 3 which is installed on the rear side of the light-emitting module 2 and is thermally coupled with a part of the outer shell 21, a light distribution member 4 which surrounds the surrounding of the light emitting part 23 of the light emitting module 2 and has a reflecting surface expanding toward the irradiation direction of light, an installation frame 6 of nearly cylindrical shape which is installed at the surrounding of the light distribution member 4 and has thermal conductivity, and a connecting member 5 which connects a part of the outer shell 21 in the light emitting module 2 with the installation frame 6 and transmit heat from the outer shell 21 to the installation frame 6.
