SOLID STATE CONTINUOUS WHITE LIGHT SOURCE
First Claim
1. An illumination system comprising:
- a housing enclosing a space;
a metal platform having a first substantially planar surface and a second surface;
the metal platform dividing the enclosed space into a first volume defined by the first substantially planar surface and the housing, and a second volume defined by the second surface and the housing;
a plurality of light sources positioned within said first volume, each light source having a solid state light source and a metal base and emitting a light beam;
each metal base of each of the plurality of light sources mounted to said substantially planar surface of said platform;
each metal base providing a heat conducting path between a solid state light source and the metal platform whereby heat generated by the solid state light source is conducted via the base to the platform; and
a fan configured to provide airflow through the second volume to dissipate heat from the second surface of the metal platform.

Abstract
A solid state illumination system is provided as a replacement for conventional arc light, metal halide and Xenon white-light sources for applications in life sciences including, microscopy, fluorescence microscopy, and endoscopy. The solid state illumination system generates high quality white light output from LED light sources. The white light output is continuous in the visible spectrum from 380 nm to 650 nm and is suitable for imaging all the most common fluorophores and fluorescent proteins. In embodiments, an LED light pipe engine is used to generate a portion of the spectral content of the white light output. In alternative embodiments the solid state illumination system produces light output of a selectable color.
