Problems solved by technology

However, beam deflection units with resonantly oscillating mirrors have the disadvantage that the velocity of the focal point produced on the illumination layer element is reduced on the edge side, that is, in the region of the return of the mirror movement. slow or the velocity is reduced to zero, and then the mirror accelerates again at its rotational velocity

Embodiment Construction

[0027] Figure 1 has been described in the introduction of this description together with the unique light distribution shown.

[0028] figure 2 The structure according to the invention of a lighting system 100 with two lighting devices 1 is shown, and these lighting devices 1 can form individual light modules in the headlights of vehicles, so that two lighting devices can be arranged in the headlights The device 1 or the lighting devices 1 themselves form the headlights of the vehicle and are respectively arranged spaced apart from one another. During operation of the two lighting devices 1 , a light distribution B around the center axis 18 can be generated in the main deflection direction 15 , as will be described in detail below.

[0029] The lighting devices 1 each have a light source 10 for generating a light beam 11 and are provided with a beam deflection unit 12 having a mirror 16 which is set in a pivoting motion resonantly on a spatial axis. The light beam 11 is inc...

Abstract

The invention relates to an illumination device (1) for a vehicle, comprising a light source (10) for generating a beam of light (11) and a beam deflection unit (12) for deflecting said beam of light (11), a luminescent layer element (13) being provided which, selectively in its planar extension, can be illuminated with the beam of light (11) by means of said beam deflection unit (12) such that light for projection in front of the vehicle can be generated by illuminating said luminescent layer element (13). According to the invention, a reflector element (14) is provided which is arranged adjacently to the luminescent layer element (13), said reflector element (14) being configured such that the luminescent layer element (13) and the reflector element (14) can be illuminated by the deflected beam of light (11), and the beam of light (11) incident on said reflector element (14) can be deflected onto the luminescent layer element (13).

Description

technical field [0001] The invention relates to a lighting device for a vehicle having a light source for generating a light beam and a beam deflection unit for deflecting the light beam, wherein a lighting layer element is provided which can be positioned at Its surface extension is selectively illuminated with the light beam by means of a beam deflecting unit, and wherein the illumination by the illumination layer element can generate light for projection in front of the vehicle. A vehicle is here understood to be a motor vehicle, truck, motorcycle, electric bicycle, scooter or the like. Background technique [0002] DE 10 2010 028 949 A1 discloses a lighting device for a vehicle which has a light source which is designed as a laser beam source and which emits a laser beam, for example with a blue wavelength. The laser beam can be moved by means of a scanning movement of the mirror over the illumination layer element by means of the beam deflection unit which includes the...
