Enhanced LED illuminator
First Claim
1. An ophthalmic illuminator comprising:
- an illumination source; and
an optical fiber for transmitting a combined light beam from the illumination source to a site;
wherein the illumination source comprises;
a plurality of light emitting diode (LED) chips optically coupled to a corresponding plurality of light pipes, the plurality of LED chips and light pipes arranged in a configuration such that the plurality of light pipes converge together at their distal ends to form a box having five sides formed by the distal ends of the light pipes and an open side from which the combined light beam, composed of light from a plurality of light beams generated by the LED chips and transmitted to the box by the light guides, is emitted.

Abstract
An ophthalmic illuminator is disclosed, one embodiment comprising: an illumination source and an optical fiber for transmitting a combined light beam from the illumination source to a site, such as a surgical site within an eye, wherein the illumination source comprises a plurality of light emitting diode (LED) chips optically coupled to a corresponding plurality of light pipes, the LED chips and light pipes arranged in a configuration such that the light pipes converge together at their distal ends to form a cubic box having five sides formed by the distal ends of the light guides and an open side from which the combined light beam, composed of light from a plurality of light beams generated by the LED chips and transmitted to the cubic box by the light guides, is emitted. The luminance of the combined light beam has a luminance greater than the luminance of any one of the plurality of LED chips.
