The invention discloses a light source system, comprising a wavelength conversion apparatus, a filtering apparatus and a dodging apparatus. The wavelength conversion apparatus comprises at least two fluorescent areas, wherein at least two fluorescent areas are provided with wavelength conversion materials used for receiving exciting light and generating excited light; the filtering apparatus is provided with N light processing diaphragms which are successively arranged in the emergent light path of the excited light, wherein a one-to-one correspondence is formed between the light processing diaphragms and the fluorescent areas in the wavelength conversion apparatus; each light processing diaphragm reflects the excited light generated by the fluorescent area in the wavelength conversion apparatus corresponding to the light processing diaphragm to the dodging apparatus, and (N-1) light processing diaphragms among the N light processing diaphragms transmit the excited light generated by the fluorescent areas in the wavelength conversion apparatus not corresponding to the light processing diaphragms, wherein a minimum N is the number of the fluorescent areas of the wavelength conversion apparatus. According to the invention, the problem of greater space occupation caused by the loosened structure of a light source system of the prior art is solved.
Description
technical field [0001] The invention relates to the field of light source systems, in particular to a light source system and a projector. Background technique [0002] At present, the white light source used in projectors is mainly UHP (Ultra High Pressure, ultra-high pressure mercury lamp) bulb, which has high brightness, but its lifespan is only 3000 hours, and the replacement of the lamp is expensive, so it cannot meet the needs of long-term use. [0003] In recent years, with the development of semiconductor light source technology, it is an important technical development direction to replace UHP light bulbs with semiconductor light sources. Such as figure 1 It is a light source system in the prior art, a laser light source 101 is used as an excitation light source, and the excitation light is incident on a reflective fluorescent wheel 102. The structure of the fluorescent wheel is as follows figure 2 As shown, there are fluorescent materials of different colors on ...
