Description

Technical Field

[0001] The utility model belongs to the technical field of projection display, and in particular relates to a reflector adjustment device. Background Art

[0002] At present, reflectors are widely used in projection products. They are optical elements that work according to the law of reflection. In the use of optical instruments, the main function of reflectors is to change the light by reflecting it. Different inclination angles of reflectors will result in different reflection angles for the same incident light, thus making the paths of the reflected light different. Therefore, the installation position of the reflector has a great influence on the reflection direction of the light beam. Usually, after the reflector assembly is fixed, in order to ensure that the light beam can enter the next set of lenses without deviation, it is often necessary to adjust the angle of the reflector assembly.

[0003] In large projector models, the reflector assembly has ample adjustment space and strong operability. However, in small projectors, due to the complex and compact structure of the projector, the adjustment of the small reflector assembly is difficult and the operation is difficult. In addition, due to the small structural components, slight adjustments will have a greater impact on the direction and position of the reflector. Utility Model Content
