Problems solved by technology

Therefore, when the rotating motor starts to rotate and the motor shaft of the rotating motor swings, the fluorescent wheel 107 will move back and forth relative to the predetermined design position, so that the light source generated by the above-mentioned light source device will also be The fluorescent wheel 107 moves back and forth to produce periodic brightness changes, thus causing periodic light and dark changes of the same projected picture and uneven brightness of the picture, reducing the quality of the projected picture
At the same time, the system of the above-mentioned existing light source device is also relatively complicated, and it is difficult to install and adjust.
In addition, in the light source device in the prior art, the high-speed rotating motor itself is also a potential safety hazard
[0014] It can be seen from the above that the light source device in the prior art still has some of the above-mentioned problems. Therefore, it is necessary to provide a better light source device, so as to avoid the problem of periodic brightness changes of the light source and improve the quality of the projected picture.

Abstract

The invention discloses a light source device, a light source production method and a laser projection machine containing the light source device. The light source device comprises a first laser light source, an alignment component, a reflection component, a first light-gathering component, a dichroic component, a driving component, a wavelength conversion component, a third light-gathering component and a light reception component. According to the light source device, the light source production method and the laser projection machine containing the light source device, the problem that the light source is periodically changed in brightness can be effectively avoided, and the picture quality of the projection machine is greatly improved.

Description

[0001] This application is a divisional application of the Chinese invention patent application 201310087954.6 filed on March 19, 2013 with the title of "Light Source Device, Light Source Generation Method, and Laser Projector Including Light Source Device". technical field [0002] The invention relates to laser projection technology, in particular to a light source device, a method for producing a light source and a laser projector including the light source device. Background technique [0003] In recent years, laser projectors have been widely used in various occasions due to their long life, high screen brightness and rich colors, such as TV projection, miniature projection, and some commercial, educational and home entertainment systems. [0004] As we all know, an optical picture needs to be composed of at least light waves of different dominant wavelengths, for example blue, green and red light waves. In the current existing technology, usually a light source of one ...
