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.

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.

Abstract: An alarm sound emitting apparatus is installed at inside of an outer shell member surrounding a space and emits alarm sound to outside by vibrating an outer shell member. The alarm sound emitting apparatus is provided with a piezoelectric element for generating vibration, a support rod for supporting the piezoelectric element and transmitting vibration, an elastic member for pressing the support rod to the vibrating plate, a magnet for fixing the support rod to the vibrating plate, a circuit board formed with various circuits including a circuit of driving the piezoelectric element, and a cabinet for containing respective elements of the piezoelectric element and the like.
