LED module and lighting device for a motor vehicle with several such LED modules
A light module of a lighting device of a motor vehicle including at least three optical elements for deflecting the light beams emitted by the light source arranged in succession in the beam path of the emitted light that produces a pre-defined light distribution on a lane in front of the motor vehicle. The first optical element comprises a first reflector element, which reflects the light beams emitted from the light source, the second optical element, which is arranged downstream from the first reflector element in the beam path, comprises a second reflector element and the third optical element, which is arranged downstream from the second reflector element in the beam path, comprises a lens element which, in cooperation with the second reflector element, projects the light beams previously deflected to the two reflector elements to realize the predefined light distribution on the lane in front of the motor vehicle.

The invention relates to a microprojection light module (1) for a motor vehicle headlight, comprising at least one light source (2) and at least one projection device (3), which images the light exiting the at least one light source (2) into a region in front of the motor vehicle in the form of at least one light distribution, wherein the projection device (3) comprises an entrance lens system (30) including one, two or more micro entrance lenses (31), which are preferably arranged in an array, and an exit lens system (40) including one, two or more micro exit lenses (41), which are preferably arranged in an array, wherein each micro entrance lens (31) is associated with exactly one micro exit lens (41), wherein the micro entrance lenses (31) are designed in such a way and/or the micro entrance lenses (31) and the micro exit lenses (41) are arranged with respect to one another in such a way that substantially all the light exiting the micro entrance lens (31) enters exactly only the associated micro exit lens (41), and wherein the light preshaped by the micro entrance lenses (31) is imaged by the micro exit lenses (41) into a region in front of the motor vehicle as at least one light distribution (LV1to LV5; GLV), wherein a first diaphragm device (50) is arranged between the entrance lens system (30) and the exit lens system (40), wherein at least one second diaphragm device (60, 70) is arranged between the entrance lens system (30) and the exit lens system (40).
Primary optical structure, high-beam lighting device, anti-glare high-beam lamp and vehicle
Disclosed are a primary optical structure, a high-beam lighting device, and an anti-glare high-beam light. The primary optical structure comprises a reflection unit and a shading structure located in front for blocking part of the reflected light from the reflection unit. The primary optical structure is configured for use in a left vehicle lamp or a right vehicle lamp, where the shading structure is arranged at a left side portion or a right side portion of the lamp, respectively. The light blocked by the shading structure and the light that is not blocked are bounded by a right side edge or a left side edge respectively, and an upper side edge of the shading structure. In a vehicle lamp, the primary optical structure can form a high-beam profile having a dark area to prevent glare, such that the dark area formed has an adjustable width and position, improving driving safety.

LASER-BASED LIGHT SOURCE WITH LIGHT EMISSION CONTROL
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).
