Problems solved by technology

[0005] And because the lens mounting assembly fixes the light-emitting lens 02 directly on the light-emitting housing 01, when there is an alignment deviation between the center of the light-emitting lens 02 and the center of the receiving element of the client, it is difficult to adjust the lens 02. Therefore, from The central axis of the light beam emitted by the light-emitting lens 02 to the light-receiving components such as square rods and light valves will deviate from the central axis of the light-receiving components, resulting in poor projection quality of the projection device

Abstract

The invention discloses an optical element regulating assembly, a light emitting module and a projection device. The optical element regulating assembly includes a mounting bracket and a fine adjustment assembly, the mounting bracket has a mounting hole for mounting an optical element, and the fine adjustment assembly is used to adjust the position of the mounting bracket. By adjusting the fine adjustment assembly, the mounting position of the mounting bracket can be adjusted to adjust the position of the optical element so that the center axis of the optical element can be accurately alignedwith the central axis of a light receiving element located downstream of the optical element in the beam transmission direction. The light beam emitted after passing through the optical element can berarely lost and accurately received and utilized by the light receiving element.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to an optical element adjustment assembly, a light output module and projection equipment. Background technique [0002] At present, the projection device generally needs to be provided with a light source mechanism such as a laser light source, and optical elements such as a light-emitting lens for light processing the beam emitted by the light source mechanism, in order to reduce the loss of the beam as much as possible and ensure the accuracy of the light beam during transmission. The ground is transmitted to light-receiving components such as square rods and light valves through optical components, and then projected to the screen through a projection lens. It is necessary to ensure that the optical components are accurately positioned. [0003] However, due to the inevitable production errors of the light source mechanism, optical elements or light receiving components of the ...
