Document Type and Number:
Japanese Patent JP4553829
Kind Code:
B2
Abstract:
The rotating lamp comprises a substrate, a translucent globe mounted on the substrate, a shaft portion (3) set in the substrate, a rotatable member (19) rotatably supported by the shaft portion (3), a main reflecting mirror or reflector (5), arranged on the upper surface of the rotatable member (19), having a light reflecting surface (5a) constituted of a paraboloid, a LED (light-emitting diode) and a drive portion (21) rotating/driving the rotatable member (19), and the optical axis of the light-emitting diode and the reflecting surface (5a) of the main reflecting mirror (5) intersect with each other. Thus, a rotating lamp employing a light-emitting diode capable of delivering light emitted from the rotating lamp to a distant place by improving reflection efficiency can be obtained.
