Title:
COLOUR WHEEL MODULE, LIGHT SOURCE SYSTEM, AND PROJECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/024013
Kind Code:
A1
Abstract:
A colour wheel module, a light source system, and a projection system, the colour wheel module comprising a colour wheel (1), a colour wheel shell (2), and a heat dissipating module, the colour wheel (1) comprising a colour wheel disc (10) provided with wavelength conversion material, and the heat dissipating module comprising a fan (30), a first heat dissipating assembly (31), and a second heat dissipating assembly (32); the inside of the colour wheel shell (2) is provided with an air flow circulation channel, the colour wheel (1), the fan (30), and the first heat dissipating assembly (31) being arranged inside the air flow circulation channel, the second heat dissipating assembly (32) being arranged outside the colour wheel shell (2), and the second heat dissipating assembly (32) being thermally connected to the first heat dissipating assembly (31); the air flow produced by the fan (30) is blown toward the colour wheel (1) in the direction parallel to the colour wheel disc (10) and is blown toward the first heat dissipating assembly (31) along the air flow circulation channel, conveying the heat produced by the colour wheel (1) outside the colour wheel shell (2) by means of the first heat dissipating assembly (31) and the second heat dissipating assembly (31), and thereby increasing the conversion efficiency of the colour wheel (1) and prolonging the service life of the colour wheel (1), the light source system, and the projection system.
