The invention provides projection light source equipment and a projection device with the projection light source equipment and a light spot movement control method. The projection light source equipment comprises a monochromatic light source and a color wheel. The color wheel comprises light-color conversion units which are provided with light-color conversion material. The monochromatic light source and color wheel are arranged in turn so that light of the monochromatic light source is enabled to irradiate to the light-color conversion material. The projection light source equipment also comprises a first motor and a second motor. The monochromatic light source is installed on the first motor. The first motor drives the monochromatic light source to move linearly in a reciprocating way. The second motor is connected with the color wheel in a driving way. The second motor drives the color wheel to rotate around the central shaft of the color wheel. Or the second motor and the first motor are connected, an inclined angle is formed between the rotating shaft of the second motor and the rotating shaft of the first motor, and the second motor drives the first motor to rotate around the central axis of the color wheel. According to the projection light source equipment, a problem of high luminous efficiency loss of the projection device in the prior art can be solved.
Description
technical field [0001] The present invention relates to the technical field of projection imaging, in particular, to a projection light source device, a projection device having the same, and a method for controlling light spot movement. Background technique [0002] According to the working principle, projection devices can generally be divided into three types: DLP projection device, LCD projection device and LCOS projection device. Among them, DLP (Digital Optical Processing Technology) projection device is easier to be accepted by ordinary consumers from the perspective of cost performance. The mainstream of the current market. The DLP projection device separates the color of the light source through the color wheel, and controls the switch of the color of a single pixel through the DMD (Digital Micromirror Chip) technology, and finally forms an image and projects it on the screen. [0003] In addition, the light source of the projection device is replaced by a solid-st...
