Abstract
An illuminating device (10) for illuminating an illuminated area (110), especially an operating area, has at least one light source (20) with at least one laser (22) for the emission of laser light (L) and at least one exciting medium (30). The exciting medium is excited while absorbing at least part of the laser light (L) and emits emission light (E) of a wavelength that differs at least partly from the wavelength of the laser light (L).
Claims15
An illuminating device for illuminating an illuminated area, the illuminating device comprising at least one light source comprising:
- at least one laser for the emission of laser light;
- at least one exciting medium, which is excited while absorbing at least one part of the laser light and emits emission light of a wavelength that differs at least partly from the wavelength of the laser light, wherein the exciting medium is designed such that the exciting medium scatters a non-absorbed part of the laser light and at least partially destroys the spatial coherence thereof;
- at least one optical component arranged such that the optical component guides the laser light onto the exciting medium, the at least one optical component comprising an optical light guide comprised of the exciting medium at least partly.
A lighting fixture for an operating room for illuminating an illuminated area in the form of an operating area, the lighting fixture comprising at least one illuminating device comprising a light source comprising:
- a laser source emitting laser light;
- and
- an exciting medium receiving the emitted laser light and absorbing a portion of the laser light and emitting emission light of a wavelength that differs at least partly from a wavelength of the laser light, the exciting medium scattering a non-absorbed portion of the laser light and at least partially destroying a spatial coherence of the scattered non-absorbed portion of the laser light;
- an optical component guiding laser light to the exciting medium, at least some of the exciting medium being arranged inside the light guide.
An operating area illuminating device comprising:
- a laser source emitting laser light, said laser source comprising a laser;
- an emission component comprising an exciting medium, said exciting medium being arranged to receive the laser light from said laser source, said exciting medium partially absorbing the laser light to emit emission light of a wavelength different from a wavelength of the laser light, said exciting medium scattering a non-absorbed part of the laser light and at least partially destroying the spatial coherence of the non-absorbed part of the laser light, said exciting medium also emitting the non-absorbed part of the laser light.
