Abstract

There is described a lighting system for illuminating multiple types of objects, the lighting system comprising: at least one first light source emitting a first quantity of a first light characterized by at least one first dominant spectral component corresponding to at least one warm color; and at least one second light source emitting a second quantity of a second light characterized by at least one second dominant spectral component corresponding to at least one cool color; and at least one beam of mixed neutral white light resulting from a mixing of the at least one first light and the at least one second light, the mixed neutral white light having spectral components corresponding to cool colors and spectral components corresponding to warm colors in substantially even proportions, the at least one beam of mixed neutral light being suitable for highlighting substantially evenly at least one cool object and at least one warm object.

Claims

1. A lighting system for illuminating multiple types of objects, said lighting system comprising:

at least one first light source emitting a first quantity of a first light characterized by at least one first dominant spectral component corresponding to at least one warm color; and

at least one second light source emitting a second quantity of a second light characterized by at least one second dominant spectral component corresponding to at least one cool color; and

at least one beam of mixed neutral white light resulting from a mixing of said at least one first light and said at least one second light, said mixed neutral white light having spectral components corresponding to cool colors and spectral components corresponding to warm colors in substantially even proportions, said at least one beam of light being suitable for highlighting substantially evenly at least one cool object and at least one warm object.

2. The lighting system as claimed in claim 1, wherein said at least one first light source is a warm white light source.

3. The lighting system as claimed in claim 2, wherein said at least one second light source is a cool white light source.

4. The lighting system as claimed in claim 2, wherein said at least one second light source is a cool color light source.

5. The lighting system as claimed in claim 1, wherein said at least one second light source is a cool white light source.

6. The lighting system as claimed in claim 5, wherein said at least one first light source is a warm white light source.

7. The lighting system as claimed in claim 5, wherein said at least one first light source is a warm color light source.

8. The lighting system as claimed in claim 1, further comprising mixing optics for mixing light beams emitted by said at least one first light source and said at least one second light source to produce said mixed neutral white light.

9. The lighting system as claimed in claim 1, wherein said at least one first light source and said at least one second light source comprises a series of alternating first and second light sources.

10. The lighting system as claimed in claim 1, wherein said at least one first light source and said at least one second light source comprises a circular arrangement of a plurality of first light sources and second lights sources.

11. The lighting system as claimed in claim 10, wherein said plurality of first light sources and second light sources are randomly distributed in said circular arrangement.

12. The lighting system as claimed in claim 10, wherein said plurality of first light sources and second light sources are alternatingly distributed in said circular arrangement.

13. A method for illuminating multiple types of objects, said method comprising:

generating a first light in a first quantity from a first light source, said first light characterized by at least one first dominant spectral component corresponding to at least one warm color;

generating a second light in a second quantity from a second light source, said second light characterized by at least one second dominant spectral component corresponding to at least one cool color; and

mixing said first light and said second light to obtain a mixed neutral white light, said mixed neutral white light having spectral components corresponding to cool colors and spectral components corresponding to warm colors in substantially even proportions; and

illuminating at least one cool object and at least one warm object using said mixed neutral white light to highlight substantially evenly said at least one cool object and said at least one warm object.

14. The method as claimed in claim 13, wherein said generating said first light comprises generating a warm white light.

15. The method as claimed in claim 14, wherein said generating said second light comprises generating a cool white light.

16. The method as claimed in claim 14, wherein said generating said second light comprises generating a cool color light.

17. The method as claimed in claim 13, wherein said generating said second light comprises generating a cool white light.

18. The method as claimed in claim 17, wherein said generating said first light comprises generating a warm white light.

19. The method as claimed in claim 17, wherein said generating said first light comprises generating a warm color light.

20. The method as claimed in claim 13, wherein said mixing said first light and said second light comprises spatially positioning said first light source and said second light source so that beams of light generated by said first light source and said second light source mix together.
