Title:
ILLUMINATION SYSTEM HAVING MULTIPLE LIGHT SOURCES AND COMMON LIGHT PATH
Document Type and Number:
WIPO Patent Application WO/2020/211263
Kind Code:
A1
Abstract:
Provided is an illumination system having multiple light sources and a common light path, said illumination comprising: an optical system (10), at least one light source module (20), and at least one drive system (40); the center of the optical system (10) is coaxial with the light from a light-emitting region (21) in one of the light source modules (20); the light source module (20) is correspondingly mounted on a heat dissipation system (30); the drive system (40) is connected to the light source module (20), and drives the light source module (20) to move. By means of the method of a common light path, light sources in the light-emitting region (21) having different forms of encapsulation can emit emitted light in coaxial form, thereby achieving merging of the beams of different light sources, resulting in significant improvements in terms of mounting and adjustment and cost; the invention not only brings higher optical power to illumination systems such as fluorescence microscopy illumination, but also greatly reduces the cost of the illumination system.
