A lighting system includes a first light source module providing a first light beam, a second light source module providing a second light beam, a beam splitting element with a first and a second side, a light condensing element, and a light homogenizing element. The beam splitting element guides the first portion of the first light beam to be output from the first side to be incident on the light homogenizing element and guides the second portion of the first light beam to be output from the second side to be incident on the light homogenizing element. The beam splitting element guides the first portion of the second light beam to be output from the first side to be incident on the light homogenizing element and guides the second portion of the second light beam to be output from the second side to be incident on the light homogenizing element.

Lighting system and projection device

A color gamut conversion module, a conversion method thereof, and a projection device are provided. The color gamut conversion module includes a wavelength conversion element and a light filtering element. The wavelength conversion element includes at least two wavelength conversion regions, and the light filtering element includes at least one filtering region. Each filtering region is a single-band light filtering region or a multi-band light filtering region. In a visible light transmittance spectrum, the single-band light filtering region includes a band-pass wave band, and the multi-band light filtering region includes a plurality of first band-pass wave bands and a plurality of first cut-off wave bands. In a first color gamut mode, the wavelength conversion element and the light filtering element rotate at a first relative rate. In a second color gamut mode, the wavelength conversion element and the light filtering element rotate at a second relative rate.
