Solid state continuous white light source

摘要

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.

主权项

1. An illumination system comprising: a housing having an interior; a metal platform having a first substantially planar surface and a second surface configured to dissipate heat; the metal platform dividing the the interior of the housing into a first portion defined by the first substantially planar surface and the housing, and a second portion defined by the second surface and the housing; a plurality of light sources positioned within said first portion of the interior of the housing, each light source having a solid state light source and a metal base and emitting a light beam; each said metal base of each of the plurality of light sources mounted to said first substantially planar surface of said metal platform; each said metal base providing a heat conducting path between the solid state light source and the metal platform whereby heat generated by the solid state light source is conducted via the metal base to the metal platform; and a fan configured to provide airflow through the second portion of the interior of the housing to dissipate heat from the second surface of the metal platform.
