摘要： Disclosed is a dust prevention and heat dissipation module and a light source system of a color wheel; said color wheel (21) is sealed in a color wheel housing (22), which color wheel housing (22) has an air inlet and an air outlet; and the dust prevention and heat dissipation module comprises a leading-in air channel (11) in communication with the air inlet of the color wheel housing (22), a leading-out air channel (12) in communication with the air outlet of the color wheel housing (22), a filtering device (13) provided at an air inlet of the leading-in air channel and an air outlet of the leading-out air channel, and a fan (14) which leads the air in via the leading-in air channel (11) and leads the air out of the leading-out air channel (12). The air in the leading-in and leading-out air channels flows by means of the fan to realize the heat dissipation of the color wheel, and the filtering device filters the air flowing through the color wheel housing, thereby reducing the amount of dust adhered to the surface of the color wheel, so as to improve the luminous efficiency of the light source system and prolong the service life of the light source system.

摘要： A light source system and a projection display device comprising the light source system. The light source system comprises at least three light sources (10, 20, 30) used for generating at least two wide-spectrum light beams, a light splitting and combining device (40), and at least two spatial light modulators, i.e. a first spatial light modulator (50) and a second spatial light modulator (60), wherein a first wide-spectrum light beam and a second wide-spectrum light beam generate light with two colours and at least four primary wavelengths after being split by the light splitting and combining device (40), thereby expanding the colour gamut range and improving the quality of image display. In addition, using two spatial light modulators to modulate light simultaneously takes account of the costs of products while guaranteeing the image display quality.
