Vehicle headlight

摘要

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.

主权项

1. A vehicle headlight comprising:
a phosphor panel having an incident surface and an output surface facing the incident surface; a casing having a first end, a second end and a space located between the first end and the second end, and the space of the casing including a first inner surface and a second inner surface facing the first inner surface; a first light source located in the space toward the first end of the casing so that light emitted from the first light source is directed toward the first inner surface of the casing; and a first mirror located adjacent the first inner surface of the casing, the light emitted from the first light source being reflected toward the incident surface of the phosphor panel, and the first mirror being configured to be movable in two directions so as to freely vary a reflecting direction of the light and configured to scan the light emitted from the first light source on the incident surface, wherein the vehicle headlight provides at least two light distribution patterns or more by using the first light source and the first mirror, and wherein the phosphor panel includes a frame either having at least one hole, which includes a wavelength converting material in the at least one hole, or having at least one cavity, which includes the wavelength converting material in the at least one cavity located toward the incident surface of the phosphor panel.
