Method of operating a headlight having a laser light source in a motor vehicle
A method is provided for operating a headlight having a laser light source in a motor vehicle. The headlight generates a light distribution from the light of the laser light source. The laser light source is activated such that the operating power of the laser light source is switched from a first power value to a deactivated operating state or is lowered to a second power value when the speed of the motor vehicle falls below a first speed threshold. The operating power of the laser light source is increased from the deactivated operating state or from the second power value to the first power value, when the speed of the motor vehicle exceeds a second speed threshold, which is greater than or equal to the first speed threshold.
Lighting device having semiconductor light source and at least one incandescent filament
A lighting device includes at least one semiconductor light source, at least one incandescent filament configured to emit electromagnetic radiation when energized, and a carrier supporting both the semiconductor light source and the incandescent filament. A screen is defined by the carrier between the semiconductor light source and the incandescent filament, so as to shield the semiconductor light source from the electromagnetic radiation emitted by the incandescent filament. The incandescent filament connected in series with the at least one semiconductor light source.

A lighting apparatus including a light generating device and at least one light wavelength conversion element and also at least one light directing means is provided. The light generating device and the at least one light directing means are configured in such a way that linearly polarized light is generated and directed from different directions to the at least one light wavelength conversion element, such that the linearly polarized light impinges on a surface of the at least one light wavelength conversion element from different directions in each case at an angle of incidence which corresponds to a Brewster angle, wherein the polarization direction of the linearly polarized light is parallel to the plane of incidence thereof.
CONFIGURABLE LIGHTING SYSTEM WITH SHARED LENS AND FIRST AND SECOND INTERNAL OPTICS FORMING A FIRST AND SECOND MODULE CONFIGURATION FOR PROVIDING TWO DIFFERENT LIGHTING FUNCTIONS
A configurable vehicle lighting module system includes a shared lens that provides a first light pattern for a first vehicle lighting function and a second light pattern for a second vehicle lighting function. The shared lens includes a mounting axis as a reference for mounting on a vehicle. First internal optics direct light toward the shared lens to provide the first light pattern; second internal optics direct light toward the shared lens to provide the second light pattern. A coupling system joins the shared lens with either the first internal optics to form a first module configuration for the first vehicle lighting function or with the second internal optics to form a second module configuration for the second vehicle lighting function. The shared lens conceals physical differences between internal optics configurations such that the first and second light module configurations appear the same when viewed along the shared lens.

The lighting device includes a body, at least one visible light source connected to the body, and at least one ultraviolet light source connected to the body. The at least one ultraviolet light source is operably coupled to the at least one visible light source. The lighting device is configured for strobing the visible light and ultraviolet light sources by turning the at least one ultraviolet light source on upon the at least one visible light source turning off and turning the at least one ultraviolet light source off upon the at least one visible light source turning on such that a reflectance material of an object, which is not being illuminated by the at least one visible light source, is illuminated by the at least one ultraviolet light source.

Vehicular lighting device
A vehicular lighting device includes a scanning light source that includes a semiconductor light source and a motor, and scans a region in front of the lighting device, with light emitted from the semiconductor light source, in accordance with motion of the motor, and a lighting circuit that changes the light quantity of the semiconductor light source in synchronization with the motion of the motor, during a normal lighting period, so as to obtain a predetermined light distribution pattern. The lighting circuit starts the motion of the motor, in response to a lighting command for headlight flashing during a stop period of the motor, and continuously lights the semiconductor light source asynchronously with the motion of the motor, during a start-up period that precedes the normal lighting period.
