<P>PROBLEM TO BE SOLVED: To enable to avoid installation of an excessive transformer by operation of a direct current (DC) power output circuit, furthermore, to suppress installation cost of the circuit, and to reduce volume and weight for installing the circuit. <P>SOLUTION: An AC LED lamp of this invention has two AC power ends AC1, AC2, one light-emitting module 1, and one DC power output circuit 2. The light-emitting module 1 is electrically connected to the alternating current (AC) power end AC1, at least one of light-emitting diode units 11, 12 is included in the light-emitting module 1, and the light-emitting diode units 11, 12 are composed by connecting at least one light-emitting diode in series. The DC power output circuit 2 is also connected to the AC power end AC2 and the light-emitting module 1. In the DC power output circuit 2, one DC power end 20 is included. <P>COPYRIGHT: (C)2011,JPO&INPIT |
