VEHICLE HEADLIGHT
First Claim
1. A vehicle headlight comprising:
- a casing having a first end and a second end facing the first end, and the casing including a first inner surface and a second inner surface facing the first inner surface;
a radiator attached to the first end of the casing;
a first light source located adjacent the radiator so that light emitted from the first light source is directed toward the first inner surface of the casing;
a phosphor panel attached to the second end of the casing;
a first mirror located adjacent the first inner surface of the casing so that when light is emitted from the first light source the light is reflected toward the phosphor panel, and the first minor being configured to be two-dimensionally slanted so as to scan the light emitted from the first light source on the phosphor panel; and
a projector lens located adjacent the phosphor panel.

Abstract
A vehicle headlight including a common light distribution unit and a variable light distribution unit and a headlight system including the headlight can form a common light distribution pattern and a variable light distribution pattern using the common and the variable light distribution units. The variable distribution unit can include a light source, a phosphor panel, a mirror reflecting/scanning light emitted from the light source onto the phosphor panel and a projector lens projecting the scanning light adjacent the common light distribution pattern. The headlight system can include a front sensor detecting a surrounding condition, and can control the common and the variable light distribution units to form an optimum light distribution pattern in accordance with surrounding conditions. Thus, the disclosed subject matter can provide a headlight system including a headlight that can form an optimum light distribution pattern in accordance with surrounding conditions and can have a simple structure.
