Abstract

The invention provides a projecting device, a light source device and a light source component. The light source device comprises an exciting light source, a wavelength conversion unit, a filtering unit, a mechanical drive unit and a driving unit, wherein the exciting light source is used for generating an exciting light; the wavelength conversion unit comprises at least a first wavelength conversion area; the filtering unit comprises at least a first filtering area which is arranged corresponding to the first wavelength conversion area; the mechanical drive unit connects the wavelength conversion unit with the filtering unit; and the driving unit is used for driving one of the wavelength conversion unit, the filtering unit and the mechanical drive unit so as to enable the first wavelength conversion area and the first filtering area to move synchronously. Through the method, the filtering unit and the wavelength conversion unit are driven by the same driving unit through the mechanical drive unit, and the devices are easy to achieve, high in 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 light source device and a projection device using the light source device. 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 ...
