The illumination system includes multiple laser light source units, a light splitting element, a wavelength conversion module, and a filter module. The laser light source units include first and second laser light source units, respectively configured to provide first and second beams. The light splitting element is located on transmission paths of the first and second beams. When the wavelength conversion module rotates synchronously with the filter module, in a first period of time, the first beam is transmitted to the filter module via the light splitting element and then reflected to a wavelength conversion region via a first color filter region of the filter module, and the second beam is transmitted to the wavelength conversion region via the light splitting element. The first and second beams are converted to a converted beam, which is transmitted to the filter module."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Illumination system and projection device","description":"An illumination system and a projection device are provided.
