Abstract
A projection device (1; 24), comprising a base (2), a support (3) and a projection head (4; 27), the support (3) being rotatable relative to the base (2) and relative to the projection head (4; 27) wherein a light guide system (10-18) is accommodated in the support, (3) and at least one wavelength-converting luminophore (22) for converting at least part of a light beam (L) generated by the at least one light source (5) is accommodated in the projection head (4; 27).
Claims15
A projection device, comprising a base, a support and a projection head, the support being rotatable relative to the base and relative to the projection head, wherein
- a light guide system is accommodated in the support, and
- at least one wavelength-converting luminophore for converting at least part of a light beam generated by the at least one light source is accommodated in the projection head
The method for operating a projection device, comprising at least the following steps:
- feeding light into a support which is rotatably connected to a base;
- conducting the light through the support;
- transmitting the light fed into the support to a projection head which is rotatably connected to the support;
- conversion, in the projection head, of at least part of the light transmitted into the projection head into at least one wavelength-converted light;
- and
- output of at least the wavelength-converted light from the projection head.
