When a position of an adjustable shade (4) is switched from a low beam position to a high beam position, a spring (7) acts so as to attenuate an repulsion force or attraction force of the solenoid (6) rapidly due to a sudden increase in an elastic force of...

The method involves producing a first light function with a shorter range using a first light source (1) and producing a second light function with a longer range using a second light source (2). The light density of the light emissions from the first sour...

A switching device for selection of high/low beam has a bulb base (2) set in a lamp shield (5) for accommodating a lighting element (3), wherein the bulb base (2) is connected with an electromagnetic valve (4), which is turned electrically on or off to sho...

The angular position of each road illuminating filament (30) is between -90 an +90 degrees. The angular position ( beta ) of the road filament of the left headlamp is different from the angular position ( beta ) of the road filament of the right headlamp. ...

A headlamp for a vehicle having at least one light guide mechanism composed (50) of an elliptic reflector (2) which is formed generally in a half part along the major axis, a light source (3) which is disposed at a first focal point (f1) thereof and a shie...

A halogen bulb (3) provides both visual and infrared light. A shutter (4) has a filter which permits only the passage of the latter. In the dipped position the shutter is raised to restrict the area illuminated by the light beam. In this position the infra...

A projector headlamp utilising only a single HID bulb for projecting light in a forward direction generally along a horizontal axis selectably between low beam and high beam conditions while shifting the hot spot as required between these conditions.
