Prism effect system comprising multi-regional color filter and multi-faceted prism

1. A light fixture comprising:

at least one light source generating light;

a light collector configured to collect at least a part of said light and to convert said light into a light beam propagating a long an optical axis, where said light beam is concentrated at an optical gate arranged along said optical axis;

an optical assembly comprising at least one optical front lens, wherein said optical assembly is configured to project at least a part of said light beam along said optical axis; and

a prism effect system arranged between said optical gate and said optical front lens, said prism effect system comprising:

a multi-faceted prism, and

a multi-regional color filter comprising a plurality of color filter regions having at least two different color filtering properties,

wherein said multi-faceted prism and said multi-regional color filter are arranged adjacent to each other.

2. The light fixture according to claim 1 , wherein the number of color filter regions in said multi-region color filter equals the number of facets in said multi-faceted prism, and wherein said color regions have substantially the same extent as said facets of said multi-faceted prism.

3. The light fixture according to claim 2 , wherein each of said color filter regions is aligned with a corresponding facet of said multi-faceted prism.

4. The light fixture according to claim 1 , wherein at least one of said multi-faceted prism and said multi-regional color filter is rotatable around an axis inside said light beam.

5. The light fixture according to claim 1 , wherein each of said multi-faceted prism and said multi-regional color filter is individually rotatable around an axis inside said light beam.

6. The light fixture according to claim 1 , wherein said multi-faceted prism and said multi-regional color filter are simultaneously rotatable around an axis inside said light beam.

7. The light fixture according to claim 1 , wherein at least one of said facets of said multi-faceted prism comprises a color filter having one or more color filter properties.

8. The light fixture according to claim 1 , further comprising an additional multi-regional color filter that includes a plurality of color filter regions having at least two different color filtering properties and is arranged adjacent to said first multi-regional color filter or said multi-faceted prism.

9. The light fixture according to claim 1 , wherein said optical assembly further comprises an optical focus group that includes at least one optical focus lens, and wherein said prism effect system is arranged between said optical focus group and said optical front lens.

10. The light fixture according to claim 9 , wherein said optical focus group and said prism effect system are simultaneously moveable along said optical axis.

11. The light fixture according to claim 1 , wherein:

said multi-faceted prism includes a first prism comprising an entrance surface and a multi-faceted exit surface, and

said prism effect system further comprises a second prism comprising a multi-faceted entrance surface and an exit surface,

wherein said entrance surface of said first prism faces towards said at least one light source, and said multi-faceted entrance surface of said second prism faces said multi-faceted exit surface of said first prism,

wherein said first and second prism are rotatable in relation to each other around an axis inside said light beam, and

wherein said multi-faceted exit surface of said first prism and said multi-faceted entrance surface comprise an identical number of inverted facets.
