| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To make it possible to light an incandescent lamp without shortening the life. <P>SOLUTION: A lighting circuit device for the incandescent lamp in a vehicle includes input terminals (J1, J2) to which an onboard source voltage (UB) nearly equal to a DC voltage is applied and output terminals (J3, J4) connected to the incandescent lamp (Lp). In the lighting circuit device, an inverter for supplying an output voltage (UA) nearly equal to an AC voltage to the output terminals (J3, J4) is provided. <P>COPYRIGHT: (C)2004,JPO</p> |
