Abstract
A rotating lamp comprises a translucent globe, a shaft portion, arranged in the globe, made of a material containing metal, an LED device provided on the shaft portion, a rotatable support member rotatably set along the outer peripheral direction of the shaft portion, a reflecting mirror supported by the rotatable support member for reflecting light received from the LED device, a driving portion rotating/driving the rotatable support member and a heat radiating portion provided on the shaft portion. Thus, heat generated in LED devices can be discharged and a problem resulting from heat can be solved.
