VEHICLE HEADLAMP APPARATUS AND CONTROL METHOD THEREOF
First Claim
1. A vehicle headlamp apparatus comprising:
- a first lamp configured to selectively produce a first high beam light distribution pattern and an infrared light distribution pattern;
a second lamp configured to selectively produce a second high beam light distribution pattern and a low beam light distribution pattern;
a vehicle detector which detects a vehicle running ahead; and
a condition-dependent selection controller which controls the first and second lamps, whereinthe condition-dependent selection controller controls the second lamp to produce the low beam light distribution pattern if the vehicle detector detects a vehicle and to produce the second high beam light distribution pattern if the vehicle detector detects no vehicle, andthe condition-dependent selection controller controls the first lamp to produce the infrared light distribution pattern, irrespective of whether the vehicle detector detects a vehicle.

Abstract
A vehicle headlamp apparatus is provided. The vehicle headlamp apparatus includes a first lamp configured to selectively produce a first high beam light distribution pattern and an infrared light distribution pattern, a second lamp configured to selectively produce a second high beam light distribution pattern and a low beam light distribution pattern, a vehicle detector which detects a vehicle running ahead, and a condition-dependent selection controller which controls the first and second lamps. The condition-dependent selection controller controls the second lamp to produce the low beam light distribution pattern when the vehicle detector detects a vehicle and to produce the second high beam light distribution pattern when the vehicle detector detects no vehicle. The condition-dependent selection controller controls the first lamp to produce the infrared light distribution pattern, irrespective of whether the vehicle detector detects a vehicle.

8. A method of controlling a vehicle headlamp apparatus, the vehicle headlamp apparatus comprising:
-
a first lamp configured to selectively produce a first high beam light distribution pattern and an infrared light distribution pattern; and a second lamp configured to selectively produce a second high beam light distribution pattern and a low beam light distribution pattern, the method comprising; detecting a vehicle running ahead of a vehicle on which the first lamp and the second lamp are mounted; controlling the second lamp to produce the low beam light distribution pattern if a vehicle running ahead is detected controlling the second lamp to produce the second high beam light distribution pattern if no vehicle running ahead is detected; and controlling the first lamp to produce the infrared light distribution pattern, irrespective of whether a vehicle running ahead is detected. - View Dependent Claims (9)
