Spectroscopy light source
First Claim
1. A spectroscopy light source for use in spectroscopy systems that measure the light absorption characteristics of a target comprising:
- (a) a light source made of a semiconductor;
(b) an electrode in electrical connection with the semiconductor, the semiconductor radiating light at a primary wavelength when energized;
(c) a luminescent material placed between the semiconductor and the target, the luminescent material producing light at a range of desired wavelengths when being irradiated by light radiating from the light source.

Abstract
A light source for a spectroscopy unit that measures tissue includes a block for engaging tissue and a light source. The block is formed of translucent material. The light source is positioned in close proximity to the block either directly or through use of a light fiber. The light source produces light at a single wavelength or small range of wavelengths shorter than the desired range of wavelengths to be produced by the light source for the spectroscopy unit. A luminescent material is placed in the light path between light source and the tissue to produce the desired wavelength of light when pumped by the light source.
