<P>PROBLEM TO BE SOLVED: To provide a light-emitting apparatus free from the risk of electric shock during installation. <P>SOLUTION: A light-emitting apparatus of the present invention receives an external power. A switching unit is electrically connected to a light-emitting unit to form a serial circuit. A first electrical connection element is electrically connected to the external power and the light-emitting unit. A second electrical connection element is electrically connected to the external power and the switching unit. A sensing unit is electrically connected to the first electrical connection element, the second electrical connection element, and the switching unit. When it is detected that currents flow between two electrical input terminals of the first electrical connection element and between two electrical input terminals of the second electrical connection element, the sensing unit controls the switching unit to turn on to enable the light-emitting unit to receive the external power and start to emit light. Thus, users can avoid the risk of electric shock when installing the light-emitting apparatus. <P>COPYRIGHT: (C)2013,JPO&INPIT |
