Abstract
A steerable lighting and/or optical device for a vehicle. A light source transmits a light beam to a rotating mirror which scans or points the light transversely ahead of the vehicle to create a desired beam shape. An intensity of the light source may be modulated during sweeping, including modulation to zero intensity, to control the pattern of light generated by the sweeping beam.
Claims20
A steerable lighting and/or optical device for a vehicle, comprising:
- at least one light source which produces a fan of light definable into sectors;
- a control system configured to determine light intensity for each sector and to energize at least one determined pattern of light projected ahead of the vehicle.
A steerable lighting and/or optical device for a vehicle, comprising:
- a rotating drum having reflective facets on its periphery which sweep past a reference point;
- at least one light source which projects light toward said reference point, which the sweeping facets reflect into a fan of light which is projected from the vehicle;
- a control system which senses rotational position of said rotating drum and modulates said at least one light source according to a mode of operation:
- which mode is selected by a human driver from a group of possible modes of operation;
- and
- which selected mode produces a selected pattern or beam of light.
