摘要： A chromaticity variable type road projection lamp system applied to a vehicle is composed of a chromaticity variable lamp that radiates a road surface radiation content, which is generated by reflecting the lights emitted from a first projection light-emitting diode (LED) of a warm white color and a second projection LED of a cool white color disposed in the direction symmetrical to a DMD at the tilting angle, with a projection beam from a chromaticity variable road projection, and radiates the low beam by comparing the warm white color of the first lamp LED and the cool white color of the second lamp LED with the road surface radiation content in chromaticity.

摘要： A system includes a first primary optics that receives light from a first light source and projects it onto a transparent shutter and a secondary optics. A second primary optics receives light from the second light source and projects it onto the transparent shutter. The transparent shutter receives light from the first light source via the first primary optics and prevents a lower part of it from entering the secondary optics. The transparent shutter further receives light from the second light source via the second primary optics and projects it onto the secondary optics. The secondary optics receives light from the first primary optics and the transparent shutter and projects it onto a road in front of the vehicle. The transparent shutter includes an air-exposed slit that redirects the light received by the transparent shutter from the second light source toward a middle axis of the transparent shutter.

摘要： A system may have lights for providing illumination. The lights may be electrically adjustable so that the color and pattern of the illumination may be varied. Sensor data and/or other data may be used in determining how to adjust the lights. A light may have a light source such as a white light source or multicolored light source, a light collimator that receives light from the light source, and an adjustable lens array that receives collimated light from the light collimator and outputs corresponding adjustable vehicle illumination. The adjustable lens array may have fixed and/or adjustable lens elements and corresponding electrically adjustable light modulator elements.

摘要： An LED module includes a heat sink. The heat sink has a mounting surface that defines, with respect to ambient light incident thereon, one main direction of a beam perpendicular to the mounting surface and secondary directions of the beam inclined to the main direction of the beam at angles having absolute values smaller than or equal to 90 degrees. The heat sink also has a reflection surface oriented such that, with respect to the ambient light incident on thereon, a main direction of the beam of the reflection surface is perpendicular to the reflection surface and points in a direction included in the angle range determined by the main direction of the beam of the mounting surface and the secondary directions of the beam of the mounting surface. The LED module further includes an LED light source on the mounting face and pigments on the reflection surface.

摘要： A lighting device for vehicles having a first light source, a second light source and a light-shaping apparatus allocated to the first light source and the second light source, wherein the second light source is offset in relation to the first light source, at least in a direction running perpendicularly to the optical axis of the light-shaping apparatus. The light that is incident on the light-shaping apparatus from the first light source is deflected to produce a first light function and wherein the light that is incident on the light-shaping apparatus from the second light source is deflected to produce a second light function, wherein the light-directing surface of the light-shaping apparatus has a free-form surface comprising multiple varyingly curved surface elements.

摘要： A scanning light source includes a light source, and scans the output light of the light source ahead of a lamp. A control apparatus controls the lighting on/off state of the semiconductor light source in synchronization with the scanning operation of the scanning light source. The control apparatus judges the presence or absence of an abnormal state with at least one from among (i) a timing immediately before switching from a lighting-on state to a lighting-off state and (ii) a timing immediately before switching from a lighting-off state to a lighting-on state as a judgment timing.
