Abstract

A lighting device comprising a plurality of lighting modules arranged concentrically about an optical axis is disclosed wherein the plurality of lighting modules emit light in at least one of a plurality of wavelength ranges (UV, visible (e.g., blue, green, yellow, orange, red, white, etc.), IR) and are arranged at a non-parallel angle to an optical axis of the lighting device, wherein the emitted light is directed towards a lens system that focuses the light onto a viewing point. A second lighting device is disclosed, wherein the lighting device comprises a plurality of lighting modules arranged concentrically about an inner circumference of the lighting device, wherein the plurality of lighting modules emit light in at least one of a plurality of wavelength ranges (UV, visible (e.g., blue, green, yellow, orange, red, white, etc.), IR) onto a lighting director device that redirects the emitted light toward a lens system that focuses the light onto a viewing point.

First claim

What is claimed is:

1. A lighting assembly comprising:
at least one lighting source, each of said at least one lighting source comprising:
a lens assembly comprising:
at least one objective lens forming an optical axis, wherein said at least one objective lens is configured to form a focus point onto which a light passing through said lens assembly converges;
a base element opposing said at least one objective lens, said base element comprising multiple reflective surfaces facing an inner circumference of said lighting source, wherein said multiple reflective surfaces are joined at an apex angle greater than ninety (90) degrees; and
a plurality of lighting elements positioned about an inner circumference of said lighting source, wherein selected ones of said plurality of lighting elements are configured to emit said light within a first wavelength band toward said base element, and said apex angle is selected to cause said light received by said reflective surfaces to be directed to a known region on said at least one objective lens along said optical axis.

2. The lighting assembly of claim 1 , wherein selected other ones of said plurality of lighting elements are configured to emit said light within a second wavelength band toward said base element.

3. The lighting assembly of claim 1 , wherein said colored wavelength band is a blue wavelength band.

4. The lighting assembly of claim 2 , wherein said selected ones of said plurality of lighting elements and said selected other ones of said plurality of lighting elements are within a same plane.

5. The lighting assembly of claim 1 , wherein said plurality of lighting elements comprise:
at least one light emitting diode.

6. The lighting assembly of claim 3 , wherein:
selected ones of said plurality of lighting elements comprise:
an aperture holder; and
an aperture, wherein said light emitted by said at least one light emitting diode passes through said aperture holder and said aperture.

7. The lighting assembly of claim 4 , comprising:
a dome lens positioned on said aperture, wherein said light emitting diode is positioned within a focal length of said dome lens.

8. The lighting assembly of claim 1 , comprising:
a dome lens positioned proximal to said apex of said base element, wherein said light reflected by said plurality of reflective surfaces is positioned within a focal length of said dome lens.

9. The lighting assembly of claim 1 , comprising:
an electronic circuit configurated to:
apply a voltage to selected ones of said plurality of lighting elements.

10. The lighting assembly of claim 1 , comprising:
a head-borne device configured to attach to a user's head, wherein said light assembly is configured to:
attach to said head-borne device.

11. The lighting assembly of claim 1 , wherein said first wavelength band is a white wavelength band.

12. The lighting assembly of claim 1 , wherein said second wavelength band is a colored wavelength band.

13. The lighting assembly of claim 1 , wherein said angle of said apex of said base element is based on an orientation of said plurality of lighting elements with respect to said optical axis.

14. The lighting assembly of claim 2 , wherein said selected ones of said plurality of lighting elements is in a first plane and said selected other ones of said plurality of lighting elements is in a second plane.

15. The lighting assembly of claim 9 , wherein said colored wavelength band is one of:
an ultra-violet wavelength range, an infra-red wavelength range, and at least one of: a blue light wavelength range, a green light wavelength range, a yellow light wavelength range, an orange wavelength range, a red-light wavelength range and a white wavelength range.

16. A head-borne lighting system comprising:
an eyewear comprising:
a first lens; and
a second lens; and

a lighting assembly comprising:
at least one lighting source configured to emit a light, wherein each of said at least one lighting source comprises:
at least one objective lens forming an optical axis substantially perpendicular to the at least one objective lens, wherein said at least one objective lens is configured to:

form a focal point a known distance from said lighting assembly;
a plurality of lighting elements arranged about an inner circumference of said lighting source; and

a light director, positioned opposite said at least one objective lens, said light director comprising a plurality of reflective surface arranged at an apex angel greater than 90 degrees, wherein said reflective surfaces are configured to:
receive light emitted by said plurality of lighting elements; and
reflect said received light toward a known region on said at least one objective lens about said optical axis.

17. The head-borne lighting system of claim 15 , wherein said light assembly is removably attachable to said eyewear.

18. The head-borne lighting system of claim 15 , comprising:
a head mount, wherein said light assembly is removably attachable to said head mount.

19. The head-borne lighting system of claim 15 , wherein a first set of said plurality of lighting elements is configured to emit a white light.

20. The head-borne lighting system of claim 15 , wherein a second set of said plurality of lighting elements is configured to emit a colored light.

21. The head-borne lighting system of claim 15 , wherein at least one of said at least one lighting source is configured to emit a white light and at least one of said at least one lighting source is configured to emit a colored light.
