Luminaire with light source and spaced-apart luminescent body
Various embodiment may relate to a luminaire, including at least one light source, in particular a semiconductor light source, for emitting a primary light beam onto at least one spaced-apart luminescent body, wherein the luminescent body includes at least one hole and a direct light component of the respective primary light beam can be radiated through the at least one hole.
1. A luminaire comprising:
at least one spaced-apart luminescent body comprising at least one hole;
at least one first reflector surface arranged over the at least one hole;
at least one light source for emitting a primary light beam onto the at least one spaced-apart luminescent body, wherein the primary light beam comprises a direct light component that is radiated through the at least one hole; wherein conversion light emitted by the luminescent body and the direct light component are reflectively guided separately.
2. The luminaire as claimed in claim 1 , wherein the direct light component comprises a part of highest power density of the primary light beam.
3. The luminaire as claimed in claim 1 , wherein the direct light component emitted from the luminaire corresponds at most to a laser class 2.
4. The luminaire as claimed in claim 1 , wherein the direct light component has a half aperture angle between 0.5° and 15° with symmetrical cross-sectional form.
5. The luminaire as claimed in claim 1 , wherein the direct light component comprises two half apertures; wherein a first half aperture angle ranges from 0.5° to 15° and a second half aperture angle ranges from 1.5° to 30° with asymmetrical cross-sectional form.
6. The luminaire as claimed in claim 1 , wherein conversion light emitted from the luminescent body and the direct light component are radiated into a refractive optical element.
7. The luminaire as claimed in claim 1 , wherein the luminaire is a vehicle headlight or a part thereof.
8. The luminaire as claimed in claim 1 , wherein the direct light component is only incident on the at least one first reflector surface and the conversion light is incident at least on a second reflector surface wherein the at least one first reflector surface is embodied so that it reduces a radiation intensity of the direct light component.
9. The luminaire as claimed in claim 8 , wherein the at least one first reflector surface is arranged over the at least one second reflector surface with respect to the luminescent body.
10. The luminaire as claimed in claim 8 , wherein the at least one first reflector surface is arranged under an opening in the at least one second reflector surface with respect to the luminescent body.
11. The luminaire as claimed in claim 8 , wherein a first reflector comprises the at least one first reflector surface and the at least one second reflector surface.
12. A vehicle headlight comprising;
at least one luminaire comprising;
at least one spaced-apart luminescent body comprising at least one hole;
at least one first reflector surface arranged over the at least one hole;
at least one light source for emitting a primary light beam onto the at least one spaced-apart luminescent body, wherein the primary light beam comprises a direct light component that is radiated through the at least one hole; wherein conversion light emitted by the luminescent body and the direct light component are reflectively guided separately.
13. The luminaire as claimed in claim 1 , wherein the light source is a semiconductor laser light source.
14. The luminaire as claimed in claim 1 , wherein the direct light component emitted from the luminaire corresponds to at most a laser class 1.
15. The luminaire as claimed in claim 1 , wherein a second reflector surface is arranged over the at least one first reflector surface.
