Abstract

This invention discloses a light module to adjust light tube for rotation freedom position, which comprises light tube, light tube supportive rack and light tube cover part, wherein, the light tube cover parts are fixed on light tube supportive rack to cover light tube; the light tube cover parts comprise ball structure and the light tube rack is set with ball concaved tank fixed inside ball concaved tank; the cover part and light supportive rack adopt ball socket combination structure.

Description

technical field [0001] The invention relates to an optical-mechanical module, in particular to an optical-mechanical module capable of adjusting the position of a light pipe in a rotational degree of freedom. Background technique [0002] With the continuous advancement of optical technology, projectors have been widely used in various occasions. For example, in general meeting briefings (reports), in order to allow participants to clearly understand the discussion content, the moderator can operate the projector Project the relevant content or charts of the report on the display screen, so that the participants can clearly understand the content of the report by watching the data projected on the display screen. In addition, the scope of use of projectors is with the advancement of video equipment and storage media, such as high-power audio, high-storage DVD, etc., so that ordinary families can also use projectors and audio at home to project images with the help of project...
