摘要:
A vehicle headlamp includes a light emitting device disposed adjacent to a base point on an optical axis extending in a front-rear direction of the vehicle headlamp, and a transparent member disposed in front of the light emitting device. The light emitting device has a light emitting surface arranged to face forward. The transparent member is configured such that light emitted by the light emitting device enters the transparent member and is internally reflected by a front surface of the transparent member, and such that the light reflected by the front surface is internally reflected again by a rear surface of the transparent member and emitted from the front surface of the transparent member. The rear surface of the transparent member is configured to form horizontal and oblique cutoff lines.
