  • Patent number: 7819538
    Abstract: The inventive rotating lamp comprises a substrate, a translucent globe mounted on the substrate, a shaft portion set in the substrate, a rotatable member rotatably supported by the shaft portion, a main reflecting mirror, arranged on the upper surface of the rotatable member, having a light reflecting surface constituted of a paraboloid, a light-emitting diode and a drive portion rotating/driving the rotatable member, and the optical axis of the light-emitting diode and the reflecting surface of the main reflecting mirror intersect with each other. Thus, a rotating lamp employing a light-emitting diode capable of delivering light emitted from the rotating lamp to a distance place by improving reflection efficiency can be obtained.

  • Patent number: 7712909
    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.
