Problems solved by technology

[0003]In this type of frame, once the optical lens is fixed in the optical path, it is often not adjustable
Due to the influence of installation errors and deformation caused by temperature changes, the incident angle of the light incident on the optical lens will often deviate from the pre-designed value, and the outgoing light will also deviate from the predetermined optical path or position, making the use of the optical lens. The results obtained in the experiment are inaccurate, and even lead to the failure of the experiment. When it is applied to production, it may produce waste products
Although there are some spectacle frames that allow optical lenses to be adjusted, they all add more complicated auxiliary devices, resulting in higher production costs.

Abstract

The invention provides a mirror bracket, a light source generator comprising the same and a display system. The mirror bracket comprises a bracket body, wherein at least an eccentric screw and elastic compression structures corresponding to the eccentric screws are arranged on the bracket body; screw rods of the plurality of eccentric screws are fastened on the bracket body; an optical lens is clamped and fixed in the bracket body by the elastic compression structures and screw caps of the eccentric screws; and when the eccentric screws are rotated, the screw caps of the eccentric screws can jack up the optical lens, thus realizing adjustment of the optical lens. The mirror bracket, the light source generator and the display system have the following beneficial effects: the mirror bracket has simple structure and can not only be used for installing and fixing the optical lens but also conveniently adjust the optical lens to ensure the emergent light to enter into the predetermined light path or position, thus accurately adjusting and correcting the light path; and by adopting the mirror bracket structure, the light source module and the display system can achieve better light output effect and display effect.

Description

technical field [0001] The invention relates to the technical field of optical devices, in particular to a mirror frame, a light source generating device and a display system thereof. Background technique [0002] Existing optical lenses, such as light-transmitting mirrors, reflectors, beam splitters and beam-combining mirrors, etc., are usually mounted on a frame when they are used in the optical path, and then fixed to the optical path through the frame. middle. [0003] In this kind of spectacle frame, once the optical lens is fixed in the optical path, it is often not adjustable. Due to the influence of installation errors and deformation caused by temperature changes, the incident angle of the light incident on the optical lens will often deviate from the pre-designed value, and the outgoing light will also deviate from the predetermined optical path or position, making the use of the optical lens. The results obtained by the experiment are inaccurate, and even lead t...
