Abstract
A lighting assembly including a plurality of lighting sources or modules arranged concentrically about an inner circumference of the lighting device, wherein the plurality of lighting sources or 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, wherein optical characteristics of the lens system being selected to focus the light onto a viewing point a known distance from the lighting assembly. Further disclosed is a passthrough within the lighting director device that allows light positioned on a base of the lighting device to pass through the lighting director.
Claims20
A lighting device comprising:
- a lens assembly comprising:
- at least one objective lens, the at least one objective lens forming an optical axis;
- and
- a housing containing therein:
- a plurality of lighting sources positioned about an inner circumference of the housing;
- and
- a prismatic structure comprising:
- a plurality of reflective surfaces extending from a base of the housing, wherein a corresponding one of the plurality of reflective surfaces being positioned opposite a corresponding one of at least one of the plurality of lighting sources, the prismatic structure configured to:
- receive light emitted by corresponding ones of the plurality of lighting sources;
- and
- re-direct the received light emitted by the lighting sources toward the at least one objective lens, within the lens assembly;
- and
- direct the re-directed light onto the least one objective lens, wherein an optical power of the combination of the at least one objective lens of the lens assembly being selected to focus the light onto an area a known distance from lens assembly.
A lighting device comprising:
- a lens assembly comprising:
- at least one objective lens, the at least one objective lens forming an optical axis;
- and
- a housing containing therein:
- a plurality of lighting sources positioned about an inner circumference of the housing, wherein the plurality of lighting sources are arranged substantially perpendicular to the optical axis;
- and
- a prismatic structure comprising:
- a plurality of reflective surfaces extending from a base of the housing, wherein the corresponding ones of the plurality of reflective surfaces are positioned opposite a corresponding one of at least one of the plurality of lighting sources, wherein the reflective surfaces are arranged to form an apex having an apex angle between the reflective surfaces less than ninety (90) degrees, the prismatic structure configured to:
- receive light emitted by corresponding ones of the plurality of lighting sources;
- and
- re-direct the received light emitted by the lighting sources toward the at least one objective lens within the lens assembly,
- wherein an optical power of the at least one objective lens being selected to focus the light onto an area a known distance from lens assembly.
