US 11,231,165 B1 · Multiple light source configuration

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.

Dependent claims

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 lighting sources arranged about an inner circumference of said lighting assembly, and oriented at a known angle with respect to, said optical axis, each of said lighting sources configured to:
emit a light,
a light director comprising:
a plurality of reflective lateral faces extending from a base element of said lighting assembly and merging at an apex, wherein an angle of said apex being determined based on said orientation of said plurality of lighting sources with respect to said optical axis, said light director configured to:
receive said light emitted by corresponding ones of said plurality of lighting sources to re-direct said received light to a known region on said lens assembly;
and
an electronic circuit configured to:
control an application of an electrical energy to each of said plurality of said lighting sources.
