A VEHICLE LAMP, A METHOD OF ADJUSTING A VEHICLE LAMP, AND A VEHICLE WITH A VEHICLE LAMP |
摘要 |
The invention provides a lamp with adjustable beam cut-off, useful for e.g. vehicle headlamps. The lamp comprises a solid-state light source 1 and a reflector 2, as well as a movable beam limiter 3. To adjust the cut-off, the beam limiter 3 may be moved by an actuator 4. An advantage is that the beam limiter 3 reflects incident light into the emitted beam instead of absorbing it, which increases efficiency. Furthermore, because the reflector 2 and also the beam limiter 3 may be positioned very close to the light source, which may be a LED or a laser diode, they may be flat and very small. Both circumstances ensure that the beam cut-off may be adjusted very quickly. |
