  • Head lamp device for vehicle including light distribution control of an auxiliary light source
    Patent number: 5854537
    Abstract: A head lamp device for a vehicle by which a pedestrian on the opposing vehicle lane side can be easily perceived without giving glare on an opposing vehicle. The head lamp device comprises main light emitting mechanism capable of changing over a low beam and a high beam from each other; an auxiliary light emitting mechanism for lighting a front and upper portion on the opposing vehicle lane side; an opposing vehicle sensor for detecting existence of an opposing vehicle; and a control mechanism for controlling the auxiliary light emitting mechanism. The control mechanism decreases or turns off the light of the auxiliary light emitting mechanism in response to input of an opposing vehicle detection signal from the opposing vehicle sensor when the main light emitting mechanism emits the low beam and at the same time the auxiliary light emitting mechanism is turned on.
