Embodiment Construction

[0034] according to figure 1 A lighting device 1 is shown. This is part of the vehicle headlight 2 indicated schematically by dashed lines. The lighting device 1 has a light source designed as a LARP system. The LARP system has a pump light source 4 , which is preferably a blue LED or a blue laser diode, which emits pump light 6 . The light is deflected by a deflectable mirror 7 or by MEMS onto a converter or conversion element 8 . Usable light 10 is then emitted by the conversion element 8 , which is thus emitted into the environment. The pump light 6 can be modulated, wherein the usable light 10 is thus also modulated. The emitted usable light is at least partially reflected by the environment and can be detected as reflected usable light 12 by a sensor 14 of the lighting device 1 . It may be conceivable for sensor 14 to be arranged outside vehicle headlight 2 . The available light detected by the sensor 14 is then evaluated by an electronic component 16 , which is con...

Abstract

A lighting device for a vehicle is provided. The lighting device includes a light source with which at least one of useful light or assist light can be emitted into the surroundings, a sensor with which at least one of useful light or assist light reflected by the surroundings can be at least partially detected, and an electronic unit for evaluating at least one of the useful light or assist light sensed by the sensor.

Description

technical field [0001] The invention relates to a lighting device for a vehicle, which has at least one light source via which useful light and / or auxiliary light can be emitted into the environment. Furthermore, the invention relates to a vehicle headlight having a lighting device of this type. Background technique [0002] It is known from the prior art that vehicles have various safety functions which specify environmental data of the vehicle. This has the advantage, for example, of detecting curves, additional vehicles, etc. and reacting accordingly. This usually requires several sensors and, depending on the sensors, also emitters for emitting radiation. For distance measurement, ultrasonic systems or radar systems are usually used. Ultrasonic systems are used in particular for parking assistance, where only distance measurement is carried out. The radar system is used as a distance control system, but can also be used as a parking aid. As a distance control system...
