    Abstract: The disclosure provides a method for regulating a light wavelength of a projection device. The method comprises the following steps. A single-color light source is provided and emits a first chromatic light. A phosphor layer is formed on an optical path of the single-color light source, so that the first chromatic light transmits the phosphor layer. The phosphor layer transforms a part of the first chromatic light to a second chromatic light, and emits the residual first chromatic light. The residual first chromatic light is further mixed with the second chromatic light to generate a third chromatic light. The wavelength of the third chromatic light is regulated by adjusting the proportion of the luminous intensity of the residual first chromatic light and the second chromatic light.

    Abstract: A phosphor device of an illumination system is provided. The illumination system emits a first waveband light and has an optical path. The phosphor device includes a first section and a first phosphor agent. The first phosphor agent is coated on the first section. After the first waveband light is received by the first phosphor agent, the first waveband light is converted into a third waveband light, and the third waveband light is directed to the optical path, so that the third waveband light is separated into at least two color lights along the optical path.

    Abstract: An illumination system includes a wavelength-transforming device, a solid-state light-emitting element and a filter wheel. The wavelength-transforming device comprises a segment and a wavelength-transforming element disposed on the segment. The solid-state light-emitting element emits first color light in first waveband region to the wavelength-transforming device. The filter wheel is disposed on one side of the wavelength-transforming device for filtering lights via rotating. The first color light is excited as second color light in second waveband region by the wavelength-transforming device, so that the second color light is outputted with the rest of the first color light. The first and second color lights are transmitted through the filter wheel, such that three primary color lights are sequentially projected. The present invention achieves the advantages of reducing cost, simplifying fabricating processes, being available for high working temperature, and further improving image quality without using red phosphor agent or red solid-state light-emitting element.

    Abstract: A phosphor wheel includes a substrate, at least a phosphor agent and a plurality of vortex generators. The substrate has a first region and a second region. The second region has a plurality of openings. The phosphor agent is disposed on the first region for converting the wavelength of waveband light. Each vortex generator includes at least a guide vane. Each guide vane is disposed on the second region, and the projection, which is on the second region, of each guide vane is corresponded to one of the openings, such that a vortex is generated during a rotation of the substrate. Therefore, the efficiency of heat exchange is enhanced, the temperature of light spot is reduced, and further the output efficiency of light of the phosphor agent is increased.
