Document Type and Number:
WIPO Patent Application WO/2019/024499
Kind Code:
A1
Abstract:
A color wheel (40), a light source system (100) comprising the color wheel (40), and a projection system comprising the light source (100); the color wheel comprises a wavelength conversion layer (41), a heat sink (42), a filter (43) and a driving device (44); the wavelength conversion layer (41) is disposed on a top surface of the heat sink (42); one end of the heat sink (42) near the radial direction of the driving device (44) is connected to the filter (43); the outer edge of the filter (43) is connected to the heat sink (42), and the middle part of the filter (43) is connected to the driving device (44); the driving device (44) is connected to the middle part of the filter (43) and drives the filter (43) to rotate. The present invention has advantages such as being thin and light weight and having a simple assembly process.
