  • Headlamp for power vehicles
    Patent number: 5264993
    Abstract: A headlamp for a power vehicle comprises a reflector having an apex, a light source arranged in the apex of the reflector, and a dimming device which is formed so that in a position for high beam it allows light from the light source to reach a lower reflector region or allows the light to exit the same, and in a position for low beam it keeps away light from said light source from the lower reflector region or blocks light reflected from the lower reflector region. The light source is formed as a gas discharge lamp with an axial light arc, an upper reflector region is formed for producing a light distribution for low beam while the lower reflector region is formed for producing a light distribution for high beam.
