(54) Vehicle headlight


(57) The vehicle headlight (1) includes a light source (13) including: a circuit board (14) whose surface is directed toward a front area of the vehicle headlight; a plurality of semiconductor light emitting elements (15) arranged in line on the surface of the circuit board; a first reflector (19) disposed on the surface of the circuit board and configured to reflect the light emitted from the semiconductor light emitting elements toward the front area to form a lower portion (H1) of a high beam pattern; and a second reflector (18) disposed on the surface of the circuit board and configured to reflect the light emitted from the semiconductor light emitting elements toward the front area to form an upper portion (H2) of the high beam pattern, wherein the semiconductor light emitting elements are disposed between the first reflector and the second reflector; and a projection lens (32) configured to project the light emitted from the semiconductor light emitting elements toward the front area; and a changing means configured to change the upper portion (H2) of the high beam pattern by controlling an incident state of the light which is incident on the second reflector.
