The invention describes a laser-based light source (100) which is adapted to use the angular dependence of the reflection of polarized laser light (10) at a surface of a conversion material to control especially the color point of light emitted by means of the laser-based light source (100). The reflected laser light is within a first wavelength range and the converted light is in a second wavelength range different from the first wavelength range such that the color point of the light emitted by means of the laser-based light source (100) in a defined solid angle depends on the ratio between reflected and converted light. The invention further describes a corresponding method of light emission control, a vehicle headlight (200) comprising such a laser-based light source (100) and a lighting system comprising such vehicle headlights (200).

A vehicle headlight device attached to a part of a vehicle and configured to apply illumination light to a road surface on which the vehicle runs comprises: a light source device configured to Generate the illumination light; an optical unit disposed on a light axis of the light source device and configured to project the illumination light from the light source device so as to form a desired light distribution; and a polarization direction conversion device disposed in a part of a light path between the light source device and the optical unit and being able to control the illumination light from the light source device with inclusion of conversion of a polarization direction thereof for each irradiation region in accordance with a state of a position irradiated with the illumination light on the road surface.

A system may have lights. The lights may emit visible and infrared light. Infrared light may be used to illuminate objects that are monitored using infrared image sensors or other infrared sensors. Visible light may be used to illuminate objects that are viewed by users and which may be monitored using sensors. The lights may be adjustable. An adjustable light may have a light source that contains an infrared light-emitting device such as an infrared light-emitting diode and a visible light-emitting device such as a visible light-emitting diode. A reflector may reflect light from the light source towards a lens. An adjustable light-blocking device may be located between the reflector and the lens. The light-blocking device may allow infrared light to pass unimpeded while adjusting visible light passing to the lens.
