Abstract
A headlamp assembly for a motor vehicle comprising at least one headlamp, which has a light source for emitting visible light, a radiation source for emitting infrared radiation, and a light emission optics with a light entry surface, which visible light from the light source and infrared radiation from the radiation source strikes, and which has an optical exit-deflection element, which directs the infrared radiation from the radiation source toward the light entry surface of the light emission optics. The optical exit-deflection element comprises at least one optics, which broadens the infrared radiation emitted by the radiation source to form a radiation beam with a cross section broadened in a horizontal plane (HH), and a radiation distribution that has at least one intensity maximum disposed toward the edge in the radiation distribution, to one side of a vertical plane (VV), when viewed in a focal plane of the light emission optics.
