Problems solved by technology

[0007] However, the isotropic, i.e. uniformly effected radiation in all directions of the luminescent substance causes a huge loss of light intensity when imaging the luminescent substance into the far field

Embodiment Construction

[0025] figure 1A possible embodiment of the searchlight module 100 is shown. The searchlight module 100 has a radiation source 10 which is designed to emit electromagnetic radiation, for example a laser, in particular a blue laser. The electromagnetic radiation and in particular the path of the electromagnetic radiation are indicated by directional arrows. The radiation source 10 can be, for example, a laser diode, wherein the radiation source 10 emits radiation in the form of a laser beam when aligned and focused.

[0026] The radiation from the radiation source 10 impinges on a beam deflection device 11 . The beam deflection device 11 has a mirror arrangement, for example a micromirror arrangement. The beam deflector 11 can be swiveled along two spatial axes, preferably by electrical actuation. As a result, the laser beam impinging on the beam deflection device 11 can be deflected in a desired direction as a result of the electrical actuation of the mirror deflection dev...

Abstract

The invention discloses a headlight module comprising a beam directing device and a luminophore. The invention relates to a headlight module (100, 100') comprising a radiation source (10, 10'), a beam directing device (11, 11') and a luminophore (12, 12') applied to a substrate material (13, 13'); the luminophore (12, 12') can be excited to emit light by means of electromagnetic radiation emitted by the radiation source (10, 10'); a first lens array (16, 16') that includes at least one optical element is disposed between the beam directing device (11, 11') and the luminophore (12, 12'), and a second lens array (17, 17') that includes at least one optical element is disposed behind the luminophore (12, 12') in the direction of radiation (15, 15').

Description

technical field [0001] The invention relates to a floodlight module with a radiation source, a beam deflection device and a luminescent substance applied to a substrate material, wherein the luminescent substance can be excited by means of electromagnetic radiation emitted by the radiation source for use in in light emission. Background technique [0002] The headlight module from the field of motor vehicle technology enables a selection between a plurality of fixed defined light patterns such as low beam, high beam and fog lights. So-called adaptive floodlight systems are increasingly being used, which broaden the options for light distribution and enable, for example, dynamic turn signals, highway lights, city lights and severe weather lights. The selection of the light distribution can be carried out by a control unit in the motor vehicle as the case may be. [0003] A further development in the field of vehicle lighting is represented by so-called active searchlight mo...
