(
A reflector 1) is provided in the casing (main body 6) near the lamp insertion opening of the reflector, and heat sinks 2 and 2', a socket 9,
Holds a lamp. Therefore, especially in lighting fixtures using halogen lamps, the inside of the lamp sealing part becomes high in temperature, but the structure of the present invention allows this part to radiate heat and suppress the temperature rise. Furthermore, it is possible to prevent radiant heat from the reflector from reaching the socket on the back surface of the reflector, thereby suppressing excessive temperature rise on the socket side.
