  • the lighting device described therein can be used as a headlight of a vehicle and comprises a light source configured as a laser diode, the light of which is coupled into a light guide when the lighting device is in operation.
  • the light guide has a coupling-out surface which extends in the longitudinal direction of the light guide and which in particular has a roughened surface or a plurality of prisms, so that light emerges from the coupling-out surface.
  • Optical means are also provided in the form of a mirror or a lens through which the light that has passed from the coupling-out surface passes or from which the light that has passed through the coupling-out surface is reflected.
  • Lighting devices for the low beam and high beam of a motor vehicle can be implemented with different optical systems, for example with Re reflectors or with lens optics.
  • the relatively large reflectors with halogen lamps have been miniaturized ever since the introduction of LED technology, with other optical components also being made ever smaller.
  • the general design trend towards flat headlights also plays a role.
  • the miniaturization of optical components is often associated with the fact that not only a light-emitting diode (LED) is used in a narrow reflector or behind a lens system, but often a light-emitting diode assembly consisting of three or four or five light-emitting diodes positioned next to one another. This is done to create an elongated luminous surface for a reflector or a lens and to generate a wide light distribution for a glare light in a simple manner.
  • the luminous areas of the LEDs positioned next to one another do not form a coherent luminous area, which is desirable for some optical systems.
  • light-emitting diodes are used, which radiate cosine-shaped light into the entire half-space, which is often only partially used by the optical components.

  • the light can therefore preferably be emitted by the deflection means in a directed and concentrated manner in a desired direction and with a defined light distribution or a defined divergence angle. Due to the concentrated, narrow light distribution and the correspondingly high light intensities and luminance levels with a simultaneously small light exit, the lighting device can be used effectively as low beam and high beam systems.
  • the coupling surfaces of the light guide which serve as partial light emission areas, can correspond to the following optical means and effectively supply them with light.
  • the deflection means are designed as nanoscale optical surfaces that were generated in the light guide in particular by laser irradiation.
