Abstract

The invention provides a projection system, a light source system and a light source component. The light source system comprises an exciting light source, a wavelength conversion device, a filter device, a driving device and a first optical component, wherein the wavelength conversion device comprises at least one wavelength conversion region. The filter device is fixed relative to the wavelength conversion device and comprises at least one first filter region. The driving device is used for driving the wavelength conversion device and the filter device, so that the wavelength conversion region and the first filter region synchronously move; and the wavelength conversion region is periodically arranged on a propagation path of exciting light, so that the exciting light wavelength is converted into excited light. The first optical component guides the exciting light into the first filter region. The first filter region is used for filtering the excited light to improve the color purity of the excited light. Through the mode, the filter device is fixed relative to the wavelength conversion device and is driven by the same driving device; and the light source system has the advantages of simple structure, easiness for implementation, high synchronism and the like.

Description

technical field [0001] The invention relates to the technical field of light sources for illumination and display, in particular to a projection system, a light source system and a light source assembly. Background technique [0002] At present, projectors are widely used in various applications such as movie playback, conferences, and publicity. As we all know, in the light source of a projector, a fluorescent color wheel is often used to provide a sequence of colored light. Wherein, different color segments of the fluorescent color wheel are alternately and periodically arranged on the propagation path of the excitation light, and then the excitation light is used to excite fluorescent materials on different color segments of the fluorescent color wheel to generate fluorescence of different colors. However, due to the wide spectral range produced by the fluorescent material, the color purity of some fluorescent materials is insufficient, resulting in an insufficient color...
