An illumination arrangement includes a control unit, an illumination module connected to the control unit via a bidirectional first channel that features an LED matrix for generating light, and a peripheral module connected to the illumination module via a second channel. The control unit can be used to generate data for controlling the illumination module and for controlling the peripheral module. The data for controlling the illumination module and data for controlling the peripheral module can be transferred to the illumination module via the first channel. The data for controlling the peripheral module can be transferred from the illumination module to the peripheral module via the second channel. The second channel is a bidirectional channel via which data can be transferred from the peripheral module to the illumination module and, after being received by the illumination module, can be transferred to the control unit via the first channel.

The invention discloses a projector unit comprising a housing on which a light module is supported to be pivotable in two spatial directions. Via eccentrics which are supported on the housing, the light module can be rotated in two axes of rotation each having a specific angle of rotation. Preferably, via one eccentric, the light module is pivoted along with the axis of rotation and, via the further eccentric, the light module is rotated about the axis of rotation.

This disclosure relates generally to vehicle headlights and, more particularly, to camera-based control of the light emission angle of a vehicle headlight. An example headlight leveling apparatus includes interface circuitry, machine readable instructions, programmable circuitry to execute the machine readable instructions to based on at least one image captured by a front camera of a vehicle, determine a geometric relationship between an output light emitting direction of a headlight and a direction defining a current orientation of the front camera, determine a current pitch angle of the front camera based on images captured by the front camera, and control a vertical light emission angle of the headlight based on the geometric relationship and the current pitch angle of the front camera.
