The invention discloses a light source system and a projection device. The light source system comprises a first power supply, a second light source, a reflection device, a light tube and a control module, wherein the first light source is used for providing first light rays along a first optical path, and the second light source is used for providing second light rays along a second light path; the reflection device comprises a first reflection element with a first reflection surface and a second reflecting element with a second reflection surface, wherein the first reflection surface is arranged on the first light path and is used for reflecting the first light rays, the second reflection surface is arranged on the second light path and is used for reflecting the second light rays, and the light tube is used for transmitting the light rays entering the light tube after the light rays are reflected by the first reflection element and the second reflection element, and the control module is used for synchronously moving the first reflection element and the second reflection element, so as to change the corresponding positions between the light rays reflected by the reflection device and the light tube to adjust the amount of the light rays of the light tube after the light rays are reflected by the reflection device.
Description
technical field [0001] The present invention relates to a light source system and a projection device, in particular to changing the light reflected by the first reflective element and the second reflective element and the light by controlling the first reflective element and the second reflective element to move simultaneously. The relative position of the tube is used to adjust the light source system and the projection device with the light source system to adjust the amount of light entering the light tube after being reflected by the first reflective element and the second reflective element. Background technique [0002] The projection device is a device that can project images or videos on the screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signal to achieve a large-screen projection display. way to provide viewers with excellent presentation and visual effects. With the cont...
