LIGHTING DEVICE FOR VEHICLE
DRIVE
June 21, 2017
A lighting device for vehicle includes a light source, and a controller (44), wherein the light source includes a semiconductor light emitting element array (41) in which a plurality of semiconductor light emitting elements are two-dimensionally disposed, and each of the semiconductor light emitting elements is provided with fluorescence light emitting part, and the controller (44) performs such control that the semiconductor light emitting element array (41) establishes brightness distribution which is high at a central part and decreases toward peripheral parts with respect to one direction, and establishes chromaticity distribution which is high at the central part and decreases toward the peripheral parts in respect of the one direction on assumption that temperature is uniform over the central part and the peripheral parts.
