A procedure is provided for actuating at least one main headlamp of a lighting unit for a motor vehicle. An overall light distribution generated by means of at least two segments of a segmented light module is allocated to a light function. The light control switches on or switches off the light function depending on at least one electric input signal of the light control. In order to facilitate the application of an animation of a vehicle lighting for a plurality of vehicle and environmental situations, the overall light distribution of the light function is built up from a plurality of light distribution segments (a-f; a-b; a-c). Each of the light distribution segments (a-f; a-b; a-c) is generated by means of at least one segment of the segmented light module. The plurality of light distribution segments (a-f; a-b; a-c) are switched on and/or switched off by the light control in a previously determined and stored sequence.

An illumination device includes: a predetermined range illumination section capable of illuminating a predetermined range with illumination light emitted from a mobile object; and an eye direction detection section for detecting the direction of the eyes of a driver of the mobile object and/or the direction of the face of the driver. The predetermined range illumination section controls the distribution of the illumination light or the on/off of the illumination light based on the direction of the eyes of the driver and/or the direction of the face of the driver, detected by the eye direction detection section.

An optical module for motor vehicle including at least one light source capable of emitting an initial light beam and a primary optical means capable of receiving the initial light beam and having a cutoff member arranged to transform the initial light beam into a secondary light beam oriented in a longitudinal direction and exhibiting a predetermined bottom cutoff extending overall transversely. A projection means is arranged to project a final light beam exhibiting a top cutoff formed by an inverted image of the secondary light beam with cutoff, wherein the primary optical means has a light deflection member arranged to deflect a part of the light rays of the initial light beam below the cutoff of the secondary beam toward the projection means.

An optical part includes a transparent or translucent block having first and second collimators that are intended to receive the beams of first and second light sources so that the beams enter into the block. The collimators are arranged in such a way that these sources may be positioned in a plane that an intermediate exit dioptric interface toward which the first collimator guides the first beam so that this first beam exits from the block through this intermediate dioptric interface. A cutoff dioptric interface forms a folder for the first beam and for the second beam, and the first collimator with the intermediate dioptric interface and the second collimator being arranged so that each beam converges on the cutoff edge of the folder.

The disclosure describes a precollimator for a lighting device, including: a) a number of first collimator units each having an entry face and an exit plane, wherein for each first collimator unit the exit plane is wider than the entry face in a first direction and the entry face and the exit plane have the same width in a second direction that is perpendicular to the first direction and b) a second collimator unit having an entry plane and an exit face, wherein the exit face is wider than the entry plane in the second direction, and
wherein the exit plane of each first collimator unit is optically connected to the entry plane of the second collimator unit, wherein the precollimator is joined together from at least two components.

The disclosure further describes such lighting device and a method to manufacture such precollimator.

A dual CCT automotive headlight is described herein, comprising: at least one first LED configured to emit light of a first color; at least one second LED configured to emit light of a second color different from the first color; a light mixing device arranged to receive and mix light from the at least one first LED and the at least one second LED and to emit the mixed light. The dual CCT automotive headlight can not only provide homogeneous light of the first color and homogeneous light of the second color, but can also provide homogeneous light of a mixed color.

A light module, notably of a vehicle, including a semiconductor light source including a plurality of light-emitting units of submillimetric dimensions distributed in different selectively activatable light zones, at least one optic, capable of receiving the light rays emitted by the selectively activatable light zones and of deflecting them out of the light module, the shaping optic being arranged in such a way as to form an image of the light source including a plurality of pixels, the light source and the optic being arranged in such a way that these pixels exhibit an angular aperture of at most 0.4 in at least one given direction.
