Abstract (en)
[origin: EP2525141A1] A compact vehicle headlamp capable of obtaining a light distribution suitable for a front illumination of a vehicle is provided. A vehicle headlamp is provided with a cylindrical pyramid reflector 2 having a front opening 21 larger than a rear opening 22, an LED 1 mounted on the rear opening 22 of the reflector 2, and a projector lens 3 arranged to face the front opening 21 of the reflector 2. The reflector 2 includes upper, lower, left and right reflective surfaces 2r, 2d, 21, 2r each of which has a parabola shape with a focal point on the LED 1. An emitting angle of a light emitted from the reflector 2 is set greater in a lateral direction than in a vertical direction. A front end edge of the lower reflective surface 2d is formed in a shape corresponding to a cut-off line of a low beam light distribution. A notch 23 is formed on the upper reflective surface 2u and extends rearward from a front end edge.
