  • Patent number: 6533434
    Abstract: A fluorescent lamp and spotlight apparatus includes a supporting body having an interior chamber, a spotlight unit cavity, and an exterior mounting slot. A power circuit device is disposed in the interior chamber of the supporting body. A spotlight unit is disposed in the spotlight unit cavity and electrically connected with the power circuit device. A fluorescent unit foldably received in the mounting slot of the supporting body includes a shell, an illuminator protected by the shell, and an electric connector for electrically connecting the illuminator with the power circuit device. Thus, a coupling joint is rotatably attached to the supporting body and pivotally connected with the fluorescent unit, so that the fluorescent lamp and spotlight apparatus enables the user to selectively use as a spotlight torch or a fluorescent lamp while the spotlight unit can be functioned as a stand supporting the fluorescent lamp unit to extend horizontally.
