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.
Claims17
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 plurality of reflective surfaces extending from a base of the housing toward peak, wherein an angle among the plurality of reflective surfaces at the peak is less than ninety (90) degrees, each of the plurality of reflective surfaces configured to:
- receive light emitted by corresponding ones of the plurality of lighting sources positioned along an inner surface of the housing opposite a corresponding one of the plurality of reflective surfaces;
- and
- re-direct the received light emitted by the lighting sources toward the at least one objective lens, wherein the optical power of the at least one objective lens is selected, to substantially converge, by a known amount, the light from the plurality of light sources at a known distance from the lighting device, based on the angle among the plurality of reflective surfaces at the peak.
A lighting device comprising:
- a housing containing therein:
- a lens assembly comprising:
- at least one objective lens, the at least one objective lens forming an optical axis;
- 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 to a peak, wherein selected ones of the plurality of reflective surfaces are positioned opposite a corresponding one of at least one of the plurality of lighting sources, the prismatic structure being 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, wherein an optical power of the at least one objective lens is selected, to substantially converge the light from the plurality of light sources onto an area a known distance from lens assembly, based on an orientation of the lighting sources with respect to the optical axis and an angle formed among the plurality of reflective surfaces at the apex.
A lighting device comprising:
- a housing containing therein:
- a lens assembly comprising:
- at least one objective lens, the at least one objective lens forming an optical axis;
- 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 to a peak, wherein selected ones of the plurality of reflective surfaces are positioned opposite a corresponding one of at least one of the plurality of lighting sources, the prismatic structure being 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
- a plurality of wedge prisms, wherein the wedge prisms are configured to:
- alter a direction of the received re-directed light;
- and
- direct the altered directed light toward the at least one objective lens, wherein an optical power of the at least one objective lens is selected based a power of the plurality of wedge prisms to alter the direction of the re-directed light towards the objective lens.
