    摘要： Disclosed are a headlamp light-sensing detection device and a headlamp. The headlamp light-sensing detection device includes a condensing lens, a lens hood and a light-sensing element. The condensing lens is arranged in front of the light-sensing element, to converge external light to the light-sensing element. The lens hood is arranged between the light-sensing element and the condensing lens, and may be configured to shield the light which is projected to the light-sensing element by a high beam light source and a low beam light source, so as to reduce optical crosstalk, such that external ambient light is received accurately, thereby achieving a desirable light-sensing detection effect. The light-sensing element may provide photoelectric parameters according to the brightness of sensed light, and then an MCU chip collects the photoelectric parameters and provides a corresponding control signal.

    摘要： 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.

    摘要： A lamp for a vehicle using micromirrors includes a variable beam forming part that generates light and forms a variable beam pattern. In particular, the variable beam forming part includes a first optical part that irradiates the light; a beam pattern forming part that reflects the light of the first optical part to form the variable beam pattern; and a second optical part that transmits the light reflected from the beam pattern forming part. The beam pattern forming part includes a reflection part including a plurality of micromirrors; and a housing that accommodates the reflection part. The housing includes an anti-reflection member to prevent secondary reflection of the light having been reflected by the reflection part.

    摘要： A method for controlling a lighting system of a host motor vehicle with a plurality of selectively controllable elementary light sources, each able to emit an elementary light beam with the vertical angular opening of which is less than 1°. The method includes detecting a target object by a sensor system. Determining a vertical angle between a given point of the sensor system of the host vehicle and a detected point of the target object. Determining, from the vertical angle, a lower angle and an upper angle between a given point of the lighting system and, respectively, an upper cut-off and a lower cut-off intended to together vertically border the target object. Controlling the elementary light sources to emit a pixelated road light beam, as a function of the lower and upper angles, to generate, in the light beam, a dark area extending substantially between the upper and lower cut-offs.
