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 device comprising:
a lens assembly comprising:
at least one objective lens arranged on a first side of said lighting device, said at least one objective lens forming an optical axis;

a lighting assembly arranged on a second side of said lighting device, said lighting assembly comprising:
a plurality of arms extending from a base of said lighting assembly; and
at least one lighting source positioned on each of said plurality of arms, wherein said each of said plurality of arms is configured to:

adjust an angle of orientation, with respect to said optical axis, of said at least one lighting source positioned thereon; and
an electronic circuit configured to:
control an application of an electrical energy to each of said at least one lighting source on each of said plurality of arms.

2. The lighting device of claim 1 , wherein each of said at least one lighting source comprises:
a light emitting diode.

3. The lighting device of claim 2 , wherein each of said at least one lighting source comprises:
at least one of: an aperture holder comprising an aperture holder passthrough, an aperture positioned within the aperture holder, said aperture comprising an aperture passthrough and a dome lens positioned on said aperture holder, wherein said light emitting diode is positioned within a focal length of said dome lens.

4. The lighting device of claim 3 , wherein said aperture passthrough is one of: square and circular.

5. The lighting device of claim 3 , wherein said aperture passthrough is sized to enable a portion of said light emitting diode to be viewable therethrough.

6. The lighting device of claim 3 , wherein said aperture passthrough is sized to prevent said light emitting diode to passthrough.

7. The lighting device of claim 1 , wherein said at least one lighting sources configured to:
generate light in at least one of: an ultra-violet wavelength range, a visible wavelength range and an infra-red wavelength range, wherein said visible wavelength comprises at least one of: a blue wavelength range, a green wavelength range, a yellow wavelength range, an orange wavelength range, and red wavelength range.

8. The lighting device of claim 7 , wherein said angle of orientation of each of said plurality of arms is skewed from an axis parallel to said optical axis.

9. The lighting device of claim 1 , wherein at least one of said lens assembly and said lighting assembly is removably attachable to said lighting device.

10. A lighting device comprising:
a lens assembly comprising:
an objective lens, said objective lens forming an optical axis, said objective lens forming a viewing point along said optical axis a known distance from said objective lens;
a lighting assembly comprising:
a plurality of arms extending from a base on the lighting assembly,
at least one lighting source arranged on a corresponding one of each of the plurality of arms,
an electronic circuit within said base of said lighting assembly, said electronic circuit configured to:
control an application of a voltage to each of said at least one lighting source.

11. The lighting device of claim 10 , wherein each of said at least one lighting source comprises:
a light emitting diode.

12. The lighting device of claim 11 , wherein each of said at least one lighting source comprising:
at least one of:
an aperture holder comprising an aperture holder passthrough;
an aperture positioned within the aperture holder, said aperture comprising an aperture passthrough, wherein aperture passthrough is sized to view a portion of said light emitting diode, and
a dome lens, wherein said light emitting diode is positioned within a focal length of said dome lens.

13. The lighting device of claim 10 , wherein said at least one lighting source is configured to generate a light in at least one of: an ultra-violet wavelength range, a visible wavelength range and an infra-red wavelength range, wherein said visible wavelength range comprises 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.
