HEADLIGHTS HAVING ONE LIGHT SOURCE MODULE FOR A HIGH BEAM AND A LOW BEAM

摘要

A high beam and a low beam is disclosed, the headlight including: a first light source unit; a second light source unit; a first light output unit; a second light output unit; and a controller configured to adjust a light quantity irradiated from the light source in response to a low beam mode or a high beam mode, and to control a beam output of the first light output unit and the second light output unit by allowing the first optical unit to be arranged selectively on a light path between the light source unit and the second optical unit.

1. A headlight having one light source module for a high beam and a low beam, the headlight comprising:
a light source unit configured to irradiate a first beam having a characteristic of linearly polarized light; a first optical unit configured to output as a second beam having a characteristic of a circularly polarized light or an elliptically polarized light when the first beam is incident; a second optical unit configured to output the first beam directly incident from the light source unit to a first path by projecting the first beam, to output a first component of the second beam incident from the first optical unit to the first path by separating the second beam and projecting the first component, and to output a second component to a second path by reflecting the second component; a first light output unit configured to output the beam provided from the first path to an outside; a second light output unit configured to output the beam provided from the second path to an outside; and a controller configured to adjust a light quantity irradiated from the light source unit in response to a low beam mode or a high beam mode, and to control a beam output of the first light output unit and the second light output unit by allowing the first optical unit to be arranged selectively on a light path between the light source unit and the second optical unit.
