The present invention in various embodiments relates to an illuminating device for a vehicle, in particular a motor vehicle, for realizing an asymmetrical light distribution. The asymmetrical light distribution has a greater illumination depth on the vehicle's side of traffic than it does on the side of oncoming traffic.

A light module of a motor vehicle generates a spot distribution of a high-beam-light distribution formed by superimposition of the spot distribution and a base distribution generated by at least one other module. The light module comprises a plurality of separately controllable sub-modules that generate a plurality of stripe-shaped segments of the spot distribution that supplement it. Also, a headlight generates the high-beam-light distribution and comprises the light module. Furthermore, a headlight system comprises a pair of the headlights disposed in a front region toward sides of the vehicle and each of which generates the high-beam-light distribution. The headlights include corresponding light modules that generate stripe-shaped segments of left and right sides, respectively, of the spot distribution such that the stripe-shaped segments of the light modules of the headlights supplement the spot distribution or are at least partially superimposed thereon.

The invention relates to a light module (1) for a lighting device for a motor vehicle. The lighting module (1) comprises a light source (3) for emission of electromagnetic radiation, preferably in the form of light which is visible for the human eye, and a reflector (2) for focusing the emitted radiation. At its apex, in the area of its optical axis (8), the reflector (2) has an opening (7) for holding a light-emitting part (5) of the light source (3). A reflector neck (9) is formed on the reflector (2), surrounding at least a part of the holding opening (7), to which reflector neck (9) another part (4, 6) of the light source (3) is attached. In order to reduce the installation space required for lighting devices in a motor vehicle, it is proposed that the reflector (2) has a slot (17), which extends into the holding opening (7), below the holding opening (7), the width of which slot (17) transversely with respect to the optical axis (8) of the reflector (2) is greater than the width of the light-emitting part (5) of the light source (3). The lamp (3) can therefore be replaced more easily, and in less space.

A headlight device for a vehicle has at least two headlights, each emitting a screened light beam with an upper bright-dark limit, which on a counter traffic side and on a traffic side has different portions. A portion on the counter traffic side is arranged deeper in a vertical direction than a portion on the traffic side, and the portion on the traffic side extends so as to ascend starting from the portion on the counter traffic side over a part of the extension of the portion on the traffic side. The headlights are formed so that the light bundles are emitted with different bright-dark limits. At least one headlight emits a first light bundle with a bright-dark limit, with the portion which on the traffic side is located higher in a vertical direction than the portion of the bright-dark limit at the traffic side of a second light bundle emitted by at least one second headlight. A direction of the second light bundle is changeable so that a position of its bright-dark limit is changed at least in a vertical direction.

The invention relates to a light module (1) for an illumination device (20), in particular for a headlight, for a motor vehicle. The light module (1) comprises a plurality of light sources (2) for emitting light beams (4, 5), at least one primary optical unit (6; 12) for focusing the emitted light beams (4a, 5a), a stop arrangement (8) in the beam path of the focused light beams (4b, 5b), and at least one secondary optical unit (9) for imaging the focused light beams (4b, 5b) which passed the stop arrangement (8) on a roadway in front of the motor vehicle in order to generate a desired light distribution. In order to be able to implement a particularly compact illumination device (20), in particular with a particularly low installation height, in which moreover the exhaust heat generated by the light sources (2) during operation can escape particularly well, it is proposed that the light module (1) has at least two laterally emitting light emitting diodes (2) as light sources and at least two laterally arranged half-bowl reflectors (6), assigned in each case to at least one of the light emitting diodes (2), as primary optical units.

The invention relates to a light module (23) for a motor vehicle headlight (2), for generating an adaptive light distribution. The light module (23) comprises a light source (30, 70, 71) for emitting light, a primary optical element (31, 73, 74) for focusing the emitted light, and a diaphragm arrangement (32, 32′) for implementing a variable effective upper edge (36, 36′), which can be introduced into a beam path of the emitted and/or focused light. To provide a simple and cost effective way to improve the visibility of the driver of the motor vehicle (1), but not result in a glare to other road users, it is proposed that the diaphragm arrangement (32, 32′) is designed to implement an effective upper edge (36, 36′) is formed, which brings about the generation of a lower beam light distribution (10) with substantially horizontal light-dark boundary (13) and with an illuminated region (14) formed at a specific horizontal position above the light-dark boundary (13), which region is delimited on the right-hand side and on the left-hand side by light-dark boundaries and has an extent in the horizontal and vertical directions of in each case a few angular degrees on a measuring screen arranged at a distance in front of the headlamp(2). By pivoting the light module (23) horizontally the light can be directed precisely, the illuminated region (14) can be moved in the horizontal direction onto detected objects in a front of the vehicle (1).
