Abstract
A vehicle lamp includes a light emitter in which a plurality of light emitting elements are arranged in a matrix, a projection lens configured to focus and project light emitted from the light emitter, a light emission drive unit configured to drive the light emitting element to emit light based on an input voltage from an in-vehicle battery, and a controller configured to perform control to cause both a lower side light emitting area and an upper side light emitting area to emit light in response to a high beam lighting instruction and to cause the lower side light emitting area not to emit light in response to a low beam lighting instruction. The controller is configured to vary light amount distribution of the upper side light emitting area at a time of high beam lighting and a time of low beam lighting.
Claims9
A vehicle lamp, comprising:
- a light emitting unit in which a plurality of light emitting elements are arranged in a matrix;
- a projection lens which is configured to focus and project light emitted from the light emitting unit;
- a light emission drive unit which is configured to drive the light emitting element to emit light based on an input voltage from an in-vehicle battery;
- and
- a control unit which is configured to perform control to cause both a lower side light emitting area and an upper side light emitting area located above the lower side light emitting area to emit light in response to a high beam lighting instruction and to cause the lower side light emitting area not to emit light in response to a low beam lighting instruction,
- wherein the control unit is configured to perform control to vary light amount distribution of the upper side light emitting area at a time of high beam lighting and a time of low beam lighting.
