    摘要: Illumination device, for a motor vehicle headlight, has an illuminant and an optical device associated therewith. The optical device has adjustment means to adjust operating states (OS) of the optical device. In a first OS, the optical device forms a first light function with light of the illuminant. In a second OS, the optical device forms a second light function different from the first light function with light of the illuminant. The illuminant includes light sources spaced apart from one another, and the optical device has scattering elements to scatter the light of the light sources. The adjustment means is configured to adjust the optical device such that in the first OS, the optical device has a first normal distance to the light sources and, in the second OS, has a second normal distance to the light sources, wherein the second normal distance is greater than the first normal distance.

    摘要: A control device drives an operating current of a lighting unit formed with light emitting diodes. The lighting unit is connected to a contact pair of the control device. The control device sets at least one parameter of the operating current that depends on a diode type of the lighting unit. With the lighting unit switched off, the control device generates a measurement current and ascertains a measurement value to identify the diode type. A hysteretic regulator sets the parameter of the operating current, and a current source circuit sets a reference signal at a comparator during the operation of the lighting unit. With the lighting unit inactive, the current source circuit generates the measurement current. Alternatively, a precharge device of the control device charges an output capacitance at the contact pair by a predetermined precharge routine, and a deviation from a predetermined expected value is ascertained as the measurement value.

    摘要: The invention relates to a vehicle headlight (1) comprising a light source (2), a primary optical system (3), a projection optical system (4), a control device, an output unit and an optoelectronic component (7) having a controllable arrangement of several, individually adjustable optoelectronic elements (8) in the form of a two-dimensional matrix. Said vehicle headlight (1) is designed to emit light from at least one light source (2) in the direction of the optoelectronic component (7) and to modulate by means of the optoelectronic component (7), and to radiate at least partially in the direction of the projection optical system (4) and to form a light image in front of the vehicle. The control device is connected to the output unit. The output unit is connected to the optoelectronic component (7) and can control the optoelectronic elements (8). A light model is stored in the control device in the form of a plurality of protection points, and the control device is designed to form, from the light model, image data in the form of a two-dimensional matrix-shaped situation light distribution with a situational image resolution. The situational image resolution is essentially higher than the plurality of protective points of the light model. The image data is formed, preferably by interpolation from the protective points and can be represented on the optoelectronic component (7) by means of the output unit.
