Abstract
In one aspect, an optical system for delivering light into an optical fiber is disclosed, which comprises a phosphor-converted white light source for generating white light, a red light emitting diode (LED) for generating red light, and a light-delivery system for delivering at least a portion of said white light and said red light into an input port of an optical fiber.
Claims13
An optical system, comprising:
- a first light source,
- a second light source,
- an optical fiber extending from an input port to an output port,
- a pair of convergent lenses for focusing light emitted by the first light source into the optical fiber, and
- an elliptical reflector having an elliptical reflecting surface that is optically coupled to the second light source to transfer light emitted by the second light source into the optical fiber.
