Title:
VEHICLE LAMP FIXTURE
Document Type and Number:
WIPO Patent Application WO/2018/186187
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a vehicle lamp fixture that switches on high beams/low beams through light-emission/non-light-emission by a lower light emission region in a light-emitting unit in which a plurality of light-emitting elements are arrayed in the shape of a matrix, thereby realizing a favorable light distribution pattern both with high beams on and with low beams on. A vehicle lamp fixture according to the present invention is provided with: a light-emitting unit in which a plurality of light-emitting elements are arrayed in the shape of a matrix; a projection lens for focusing and projecting light emitted by the light-emitting unit; a light emission drive unit for driving light emission by the light-emitting elements on the basis of an input voltage from an onboard battery; and a control unit for performing a control for having light be emitted by both a lower light emission region in the light-emitting unit and an upper light emission region in the light-emitting unit that is located above the lower light emission region in response to command to turn the high beams on, and having light not be emitted by the lower light emission region in response to a command to turn the low beams on. The control unit performs a control for varying a light quantity distribution of the upper light emission region between when the high beams are on and when the low beams are on.
