<p><P>PROBLEM TO BE SOLVED: To provide, at a low cost, vehicular headlamps automatically lit and extinguished in response to brightness around a vehicle. <P>SOLUTION: The vehicular headlamps used for a vehicle is provided with: a semiconductor light-emitting module for radiating light; an optical member for radiating the light generated by the semiconductor light-emitting module to the front side of the vehicle; a voltage detection part for detecting a voltage generated by the semiconductor light-emitting module in response to the brightness around the vehicle when the semiconductor light-emitting module is lit out; and a lighting control part for lighting or extinguishing the semiconductor light-emitting module in response to the voltage detected by the voltage detection part. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
