A down-light has a main body, a substrate, a plurality of LEDs, a reflector, a central boss, a central screw and peripheral screws. The main body has a mounting area. The substrate having LEDs is assembled in the mounting area. The reflector is attached to the main body with the substrate interposed therebetween, and reflects light emitted from the LEDs. The central boss is formed on the mounting area to correspond to a central part of the substrate. The central screw fixes the central part of the substrate to the central boss from the reflector side. Peripheral screws fix the substrate to the main body by pulling the reflector from the main body side.
