Abstract

According to an embodiment, a polyhedron may be provided. The polyhedron may include a first luminescent face; and a second luminescent face.

Claims

1. A light source arrangement, comprising:

a primary light source and a secondary light source;

wherein the primary light source is configured to illuminate the secondary light source;

wherein the secondary light source comprises a polyhedron, the polyhedron comprising;

a first luminescent face, and

a second luminescent face; and

a mechanized driver fixed to the primary light source.

2. The light source arrangement of claim 1,

wherein the primary light source comprises at least one of a laser and a light-emitting diode.

3. The light source arrangement of claim 2,

wherein the primary light source comprises at least one of a plurality of lasers and a plurality of light-emitting diodes.

4. The light source arrangement of claim 1, further comprising:

a controller configured to control the primary light source and the driving mechanism, so that the primary light source is switched between an on state and an off state based on the state of the driving mechanism.

5. The light source arrangement of claim 1,

wherein said primary light source comprises a plurality of light sources.

6. The light source arrangement of claim 5,

wherein the polyhedron comprises a plurality of optical elements, each fixed to a face of the polyhedron;

and

wherein each light source of the plurality of the primary light sources is configured to illuminate at most one optical element of the plurality of optical elements at a time.

7. The light source arrangement of claim 1 wherein the polyhedron is configured so that the primary light source illuminates a plurality of luminescent faces of the polyhedron at a time.

8. A light source device, comprising:

a primary light source;

a secondary light source comprising a cylinder, wherein at least a part of the side area of the cylinder is luminescent;

a mechanized driver fixed to the primary light source; and

an integrating optical element;

wherein the primary light source, the secondary light source and the integrating optical element are arranged so that light from the primary light source is internally reflected inside the integrating optical element before arriving at the secondary light source.
