The invention provides a projection device and an illumination system. The lighting system comprises an excitation light source, a light guide element, a light filtering module, a light wavelength conversion module and a light uniformizing element. The light guide element is arranged on a transmission path of the excitation light beam from the excitation light source and is used for reflecting the excitation light beam. The light filtering module comprises a light action area and is arranged on a transmission path of the excitation light beam reflected by the light guide element. The light wavelength conversion module comprises a light wavelength conversion area and is arranged on a transmission path of the excitation light beam reflected by the light action area of the light filtering module. The optical wavelength conversion area is used for reflecting a conversion light beam converted by the excitation light beam. The converted light beam from the optical wavelength conversion module passes through the light action area of the light filtering module and then forms at least one colored light. The dodging element receives the excitation light beam from the light filtering module and the at least one colored light. The incident angle of the excitation light beam on the light guide element is theta1, and theta1gt; 0 DEG. The lighting system and the projection device are beneficial to reducing the number of optical elements.
Description
technical field [0001] The present invention relates to an optical device and an optical system, in particular to a projection device and an illumination system. Background technique [0002] In a traditional projection device, the excitation beam is transmitted to the optical wavelength conversion module through the beam splitting element, multiple lenses and multiple mirrors. The optical wavelength conversion module converts the excitation beam into a converted beam, and the converted beam is then transmitted through the beam splitting element and other lenses. to the filter module. Because the lighting system uses too many optical components, it causes problems such as difficult assembly, poor accuracy, and difficulty in reducing the size. [0003] The "Background Art" paragraph is only used to assist understanding of the present disclosure, so the content disclosed in the "Background Art" paragraph may contain some that do not form the prior art that is known to those s...
