A lighting device for vehicle, comprising: a light source; and a controller; wherein said light source includes a semiconductor light emitting element array in which a plurality of semiconductor light emitting elements (2, 20) are two-dimensionally disposed, and each of said semiconductor light emitting elements (2, 20) is provided with a fluorescence light emitting part, the lighting device being characterised in that: said controller is adapted to independently control groups of the semiconductor light emitting elements (2, 20) aligned in one direction, and wherein said controller is adapted to duty-drive said groups of the semiconductor light emitting elements (2, 20), changing current supply periods in a central part and in a peripheral part with respect to said one direction, such that the semiconductor light emitting elements (2, 20) are given higher supply power in the central part than in the peripheral part, forming a brightness distribution having a higher brightness in the central part than in the peripheral part, and in which current density is set lower in the central part than in the peripheral part, so that the current density becomes larger from the central part toward the peripheral part, while the supply power becomes smaller from the central part toward the peripheral part. a light source; and a controller; wherein said light source includes a semiconductor light emitting element array in which a plurality of semiconductor light emitting elements (2, 20) are two-dimensionally disposed, and each of said semiconductor light emitting elements (2, 20) is provided with a fluorescence light emitting part, the lighting device being characterised in that: said controller is adapted to independently control groups of the semiconductor light emitting elements (2, 20) aligned in one direction, and wherein said controller is adapted to duty-drive said groups of the semiconductor light emitting elements (2, 20), changing current supply periods in a central part and in a peripheral part with respect to said one direction, such that the semiconductor light emitting elements (2, 20) are given higher supply power in the central part than in the peripheral part, forming a brightness distribution having a higher brightness in the central part than in the peripheral part, and in which current density is set lower in the central part than in the peripheral part, so that the current density becomes larger from the central part toward the peripheral part, while the supply power becomes smaller from the central part toward the peripheral part. said controller is adapted to independently control groups of the semiconductor light emitting elements (2, 20) aligned in one direction, and wherein said controller is adapted to duty-drive said groups of the semiconductor light emitting elements (2, 20), changing current supply periods in a central part and in a peripheral part with respect to said one direction, such that the semiconductor light emitting elements (2, 20) are given higher supply power in the central part than in the peripheral part, forming a brightness distribution having a higher brightness in the central part than in the peripheral part, and in which current density is set lower in the central part than in the peripheral part, so that the current density becomes larger from the central part toward the peripheral part, while the supply power becomes smaller from the central part toward the peripheral part.
