Document Type and Number:
Japanese Patent JP2020003785
Kind Code:
A
Abstract:
To provide an illumination system and projection device.SOLUTION: An illumination system disclosed herein comprises an excitation light source module, beam splitting/combining module, wavelength conversion element, and light filtering element. The excitation light source module is configured to emit an excitation light beam. The beam splitting/combining module is disposed in a transmission path of the excitation light beam. The wavelength conversion element has a first optical region and a second optical region, which are sequentially cut into the transmission path of the excitation light beam transmitted by the beam splitting/combining module. The light filtering element is coupled with the wavelength conversion element about a common central axis.SELECTED DRAWING: Figure 1A
