Automotive lamp
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.
HEADLIGHT ASSEMBLY AND ILLUMINATION METHOD FOR ILLUMINATING AN ENVIRONMENT OF A VEHICLE
A headlamp assembly for illuminating surroundings of a vehicle, including at least one headlamp, a temperature sensor, and a control device. The at least one headlamp comprising a multiplicity of light sources, the multiplicity of light sources (being divided into a first group and at least one second group. The temperature sensor being configured to detect a temperature in the at least one headlamp. The light sources of the multiplicity of light sources being thermally coupled. The control device being configured to ascertain a current temperature ascertained by the temperature sensor in the at least one headlamp and, in the case that the current temperature in the at least one headlamp exceeds a predefined temperature threshold value, to select the first group or the at least one second group for a power reduction, depending on an operating situation of the vehicle and to reduce the power of the selected group.

REFLECTION-TYPE HEADLAMP MODULE, HEADLAMP MODULE, HEADLAMP AND VEHICLE
A reflection-type headlamp module, comprising a light source, a light-converging element, a reflecting element and a lens, wherein the light-converging element is suitable for converging light rays emitted by the light source and projecting the light rays; and the reflecting element is arranged on a light-emergent light path of the light-converging element, and is suitable for reflecting, to the lens, the light rays emitted by the light source and projecting the light rays via the lens to form an illuminating light pattern. The reflecting element of the headlamp module changes the propagation direction of light rays, so that the front and rear diameter of the module is greatly reduced. In addition, high-beam light and low-beam light can be switched quickly and noiselessly, preventing the influence of a high-beam light path and a low-beam light path on each other. Further disclosed are a headlamp and a vehicle using the headlamp.
Method for controlling two lighting modules of a headlight
A method for controlling two lighting modules of a headlight, including the following steps: definition of a non-dazzling region, wherein the non-dazzling region is at least within the second region; reduction of the brightness of the light emitted by the two lighting modules toward the non-dazzling region; determination as to whether an adjacent region exists that directly adjoins the non-dazzling region horizontally and that is a horizontal edge region of the first region; and reduction of the brightness of the light emitted by the first lighting module toward the adjacent region if the adjacent region has been determined.
