To provide a lighting fixture capable of installing even if the height of embedding at the installation portion is low and securing heat radiation.
As for a lamp 20 installed in an installation hole by a lamp installation part 23, heat generated from an LED unit being housed is radiated by radiation fins 22 installed integrally in the lamp 20. In this case, the length in radial direction of the installation hole of the radiation fins 22 is made longer than the diameter of the installation hole, thereby, the height of the radiation fins 22 can be made low while securing heat radiation area of the radiation fins 22. Thereby, even if the height of embedding in the installation hole is low, the lamp can be installed and heat radiation can be secured. Furthermore, since the length L in radial direction of the installation hole of the radiation fins 22 is longer than the diameter of the installation hole, it can be temporarily fixed by hooking the radiation fins 22 on the installation hole. Thus, installation workability is improved.
