Abstract

The invention provides an optical element adjusting module, a projecting device and a method for adjusting an optical element. The optical element adjusting module comprises a frame body, a first adjusting element and a second adjusting element, wherein the frame body is provided with a connection part and a bare engine base connected with the projecting device through the connection part; a first axis and a second axis pass through the connection part; the optical element is arranged on the frame body; the first adjusting element is arranged on the frame body and is located on the first axis; when the first adjusting element is rotated, the first adjusting element drives the frame body to rotate relatively to the bare engine base by using the first axis as a center; the second adjusting element is connected with the base engine base and is screwed with the frame body; and when the second adjusting element is rotated, the second adjusting element drives the frame body to rotate relatively to the bare engine base by using the second axis as the center. Furthermore, the invention provides the projecting device with the optical element adjusting module and the method for adjusting the optical element.

Description

【Technical field】 [0001] The present invention relates to an adjustment module, an optical device and an adjustment method, and in particular relates to an optical element adjustment module, a projection device and an adjustment method for an optical element. 【Background technique】 [0002] A projection device is a display device for producing large-scale images. The imaging principle of the projection device is to convert the illumination beam generated by the light source into an image beam through a light valve, and then convert the image beam into a projection beam through a lens, and project it onto a screen or a wall. With the advancement of projection technology and the reduction of manufacturing costs, the use of projection devices has gradually expanded from commercial use to home use. [0003] Generally speaking, a reflector can be installed in the optical engine of the projection device, and the reflector is used to reflect the illumination beam emitted by the li...
