<P>PROBLEM TO BE SOLVED: To provide a vehicular headlight system cooling a lamp part dispensing with a temperature sensor and a cooling fan exclusive for cooling of a lamp part. <P>SOLUTION: The headlight 500 is communicated with the windward side of a blower 300 for cooling a radiator 100 and a capacitor 200 through a ventilating channel 440, so that the inside of the headlight 500 is ventilated by outside air by wind blown due to rotation of the blower 300 to forcefully cool the headlight. Drive voltage of the blower is to be the highest voltage value out of three voltages of a radiator cooling drive fan voltage determined by engine water temperature, an A/C capacitor cooling drive fan voltage determined by cooling medium pressure, and a lamp cooling drive fan voltage equivalent to a necessary heat radiation volume of the headlight,determined by the velocity of a vehicle, an ambient temperature and engine water temperature. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
