ABSTRACT:
An improved startup device for controlling energization of a lamp has a base, stand coupled with the base and an illuminator connected to an electric power source. The base has a sound-collecting element mated with a housing unit so that the sound-collecting element has direct contact with the surface it is placed on. A control unit is situated within the housing unit and includes a connected startup circuit built on a circuit board, a reception element and a power-supply component. Thus, the reception element cooperates with said sound-collecting element to switch the power-supply component allowing the illuminator to make or break connection with the power source upon receiving tapping sound at the stand or through the surface. In practice, the startup device of the present invention employed in lamps affects to extend the conventional switch size to the entire floor or table area, which advantageously acts as a medium of transmitting tapping sounds to ease the task of lighting up.
