Embodiment Construction

[0021] The control of two headlights of a motor vehicle, each having a further light source, preferably an LED light source, in addition to the laser light source is described below by way of example. The laser light source is only used in addition to the LED light source when the vehicle's high beams are switched on, and is switched off during normal low beams. The laser source is controlled based on the scheme of the method of the invention. In other words, in the embodiments described here, the method according to the invention is always used with the high beams switched on. However, the method can also be carried out when generating other light distributions, for example passing beam distributions, as long as the laser source is activated in these light distributions.

[0022] figure 1 Components of the motor vehicle 1 that are relevant to the invention are shown in a schematic plan view. In particular, the wheels 4 of the vehicle and one of the headlights are shown her...

Abstract

A method is provided for operating a headlight having a laser light source in a motor vehicle. The headlight generates a light distribution from the light of the laser light source. The laser light source is activated such that the operating power of the laser light source is switched from a first power value to a deactivated operating state or is lowered to a second power value when the speed of the motor vehicle falls below a first speed threshold. The operating power of the laser light source is increased from the deactivated operating state or from the second power value to the first power value, when the speed of the motor vehicle exceeds a second speed threshold, which is greater than or equal to the first speed threshold.

Description

technical field [0001] The invention relates to a method for operating a spotlight with a laser source in a motor vehicle, a corresponding spotlight and a motor vehicle comprising the spotlight. Background technique [0002] The problem with the use of laser sources in motor vehicle spotlights is that due to the high brightness of such light sources, the eyes of other road users can be damaged by the prolonged dazzle caused by the spotlights. Such injuries to other road users should be avoided as much as possible. Contents of the invention [0003] It is therefore the object of the present invention to provide a method for operating a spotlight with a laser source in a motor vehicle, whereby injuries to other road users by the laser source can be significantly reduced or avoided. [0004] The object is solved by the method according to the invention or the spotlight according to the invention. [0005] The invention realizes a method for operating a spotlight in a motor ...
