To achieve a high-quality light distribution pattern in a lamp unit (3R, 3L) used in a vehicular lamp system that selectively irradiates the front of a vehicle. The unit (3R, 3L) includes a light source (4a, 4b), an optical shutter device (6), and an optical system (7) where the optical shutter device (6) has a first liquid crystal device (6a) having first light modulation areas (101, 102) and a second liquid crystal device (6b) having second light modulating areas (103, 104, 105). The first light modulation areas (101, 102) are arranged with a gap at least in a first direction and the second light modulation areas (103, 104, 105) are arranged with a gap at least in the first direction. The first liquid crystal device (6a) and the second liquid crystal device (6b) overlap with each other such that, in a plan view, the first light modulation areas (101, 102) and the second light modulation areas (103, 104, 105) are arranged complementarily to each other without forming a gap between the two modulation areas.

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.

A system (10), controller (16), and method (400) for controlling a light distribution pattern (22A). A light source (12) and an electrowetting lens (20) cooperate to vary a light distribution pattern (22A) of light (14A) from the light source (12). An object detector (40) is used by a controller (16) determine the location of an object (42, 58, 78) and operate the electrowetting lens (20) in order to control the light distribution pattern (22A) based on the location of the object (42, 58, 78). The electrowetting lens (20) provides for faster redirecting of light (14A) toward an object (42, 58, 78) when compared to mechanical based system (10). The light source (12) may be an array of light (14A) emitting diodes to provide a reliable, energy efficient source of light (14A).

摘要:
There is provided a light distribution controller (50) for controlling a light distribution pattern which is formed by light emitted from a vehicle headlamp (1) of a vehicle (C) so as to prevent glare light from being directed to a front vehicle (A, B) existing in front of the vehicle, based on a relative distance between the vehicle and the front vehicle in a vehicle traveling direction. The light distribution controller is configured to control the light distribution pattern so as to block or reduce light directed to a first region (90A, 90B) where the front vehicle is present, when the relative distance is larger than a first value. The light distribution controller is configured to control the light distribution pattern so as to block or reduce light directed to a second region (91) where the front vehicle is present and a third region (92) which is located outside the front vehicle and closer to a road shoulder side, when the relative distance is in a range of a second value to the first value, wherein the second value is smaller than the first value. The light distribution controller is configured to control the light distribution pattern without blocking or reducing light directed to a fourth region where the front vehicle is present, when the relative distance is smaller than the second value.
