Abstract: A method and apparatus are disclosed for a LED used in a medical device emitting a wavelength from about 200 nanometers to about 440 nanometers along a path. A composition of phosphors coats the LED to broaden the electromagnetic spectrum from about 200 nanometers to about 780 nanometers. A filter is positioned in the path to selectively permit electromagnetic radiation of a particular range of wavelengths to pass through. The medical device is used to provide a broad spectral source for medical diagnosis.

Abstract: An apparatus for a spectroscopic illumination device for medical diagnosis may include a mount having a proximal end, a distal end, a first electrical connection disposed at the proximal end, a second electrical connection disposed at the proximal end, a light path along a longitudinal axis of the mount, and a lens disposed along the light path at the distal end. The spectroscopic illumination device may also include one or more light emitting diodes coupled within the mount along the light path, each of the one or more light emitting diodes is coated with a phosphoric composition of red, blue, and green phosphors such that the one or more light emitting diodes emits a white light having a color rendering index of greater than about 95, wherein the one or more light emitting diodes are electrically coupled to the first electrical connection and the second electrical connection.
