<p><P>PROBLEM TO BE SOLVED: To provide an LED lighting device in which a plurality of kinds of LEDs can be lighted and controlled by a simple constitution. <P>SOLUTION: This is the LED lighting device provided with an alternate current generating device capable of controlling alternate current wave forms, a plurality of wirings connected in parallel to the alternate current generating device, and the LED connected to the wire, and because the light emission center wavelength and a rectification direction of the LED of at least one of the wirings out of the plurality of the wirings are different from the light emission center wavelength of the LED of other wirings, and also are the reverse direction to the reference of the rectification direction of the LED of the other wirings and the alternate current generating device, lighting control of a plurality of LEDs can be carried out by the simple circuit constitution. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
