Description of the Invention: 'Technical Field to Which the Invention Alongs>> The present invention relates to a light source system, and more particularly to a light source system for a projector for projection by a digital micromirror device. [Prior Art] In a single-chip DLP (Digital Light Processing) projector, input signals are converted into RGB data, and data is written into the memory of DMD (Digital Micromirror Device) in sequence. In the body, the white light source is focused on the color wheel through the collecting lens, and the light passing through the color wheel is then irradiated onto the surface of the DMD. When the color wheel rotates, red, green, and blue light are sequentially irradiated on the DMD. The color wheel and video image are sequential, so when the red light hits the DMD, the lens tilts to "on" according to the position and intensity that the red information should display, and the green and blue light and video signals work as such. The human visual system concentrates red, green, and blue information and sees a full-color image. Through the projection lens, the image formed on the surface of the DMD can be projected onto a large screen. More and more projectors now use white LEDs (light emitting diodes) as light sources, but there is also a projector that uses blue or ultraviolet LEDs to excite fluorescent powders to emit red, green, and blue light as light sources. . The color wheel of this projector does not have a filtering function, but is divided into three equally divided sectors on the color wheel, and is coated with red, green and blue light respectively on each sector. Fluorescent powder, when the color wheel is working, the LED light illuminates the color wheel to excite the fluorescent powder to emit red, green and blue light. 4 201033722 The projector works with the excited light. However, this kind of excitation is the same as that of the projector using the color wheel of the filter, and the brightness is not enough, especially when it is necessary to project a large area of white, the three colors are sequentially irradiated, and then the human eye's visual delay is used to generate white. The effect, so much affects the brightness of the projection. SUMMARY OF THE INVENTION It is necessary to provide a light source system that can increase the brightness of a projector. A light source system for a projector using a digital micromirror device, the light source system comprising three light sources, at least one color wheel, a motor and a control module corresponding to the color wheel, the color wheel coated with a phosphor powder The color wheel corresponds to a light source, and the light source corresponding to the color wheel emits light of a predetermined wavelength for exciting the color wheel to emit red, green or blue light, and the light source system can pass three light sources and colors The wheel emits light of three colors of red, green and blue. The motor drives the color wheel to rotate. When the light source system requires white light from the stomach, the controller controls the three light sources to emit light at the same time. Since the light source system can simultaneously output red, green, and blue light when displaying white light, when the DLP projector displays a white area, the display brightness of the white light can be improved by sequential illumination of the three colors.
