Embodiment Construction

[0057] figure 1 Shown is a lighting device 100 known from the prior art, which is designed for a transmissive mode of operation. The lighting device 100 comprises a light emission unit 200 embodied as a laser diode, with which primary light 250 (eg blue light) is irradiated onto the rear side 320 of the light conversion element 300 . Thereafter, the light conversion element 300 receives primary light 250 on the rear side 320 and emits secondary light 350 on the front side 310 .

[0058] figure 2 A similar lighting device 100 is shown, but designed for a diffuse mode of operation (reflective mode of operation). In the present illustration, the light emitting unit 200 radiates primary light 250 onto the front side 310 of the light conversion element 300 , the front side being irradiated in the region of the primary light receiving surface 330 . The light conversion element 300 emits secondary light 350 on the front side 310 in the region of the secondary light emission surfa...

Abstract

The present invention relates to a lighting device comprising: a light emitting unit configured to emit primary light; and a light conversion element arranged to be irradiated by the primary light andto emit secondary light having other wavelengths, where the light conversion element has a front face and is configured to be irradiated by the primary light in a region of the primary light receiving face on the front face and to emit the secondary light in a region of the secondary light emitting face on the front face, the light conversion element has a variable thickness in the region of theprimary light receiving surface and / or in the region of the secondary light emitting surface. The invention also relates to a corresponding light conversion element, to a light conversion device, to amethod for processing a light conversion element, and to a method for producing a light conversion device.

Description

technical field [0001] The invention relates to an illuminating device comprising a light emitting unit configured to emit primary light and a light converting element configured to be irradiated by the primary light and emit secondary light with other wavelengths. Background technique [0002] Illumination devices are known in various embodiments, for example so-called gas discharge lamps and halogen lamps. For various reasons, eg in terms of energy efficiency or reduced space requirements, preferably with simultaneous increase in brightness, lighting devices based on laser light sources are of increasing interest. Illumination devices of this type are generally constructed such that they comprise at least one laser light source, for example a laser diode, and a light conversion element. [0003] The light conversion element is used to receive light from a laser light source and re-emit light with other wavelengths, since the light emitted from one or more laser light sour...
