Abstract

The invention provides a lighting device and a reflecting mirror assembly method. The lighting device comprises a base and a reflecting mirror for reflecting a light ray, the outer side of the reflecting mirror is connected to the base through a rotating shaft, and the upper and lower ends of the reflecting mirror can rotate around the rotating shaft; and the lighting device further comprises a first adjusting component and a second adjusting component, the first adjustment component is connected between the base and the lower end of the reflecting mirror, the first adjustment component is used to adjust a rotation angle of the reflecting mirror about the rotating shaft by changing a distance between the base and the lower end of the reflecting mirror, the second adjustment component is connected between the base and the upper end of the reflecting mirror, and the second adjusting component is used to limit the rotation angle of the reflecting mirror when the reflecting mirror rotatesaround the rotating shaft and fix a relative position between the upper end of the reflecting mirror and the base when the reflecting mirror is adjusted to a preset angle. Position adjustment of the reflecting mirror in the lighting device can be performed simply and visually.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to an illuminating device and an assembly method of a reflecting mirror. Background technique [0002] With the continuous development of science and technology, more and more projection audio-visual equipment such as laser TVs have appeared in people's work and life. [0003] At present, laser TV mainly includes a screen and a projection or lighting device for projecting a TV picture on the screen. The projection or lighting device usually includes a housing base, a laser light source and a reflector. Among them, since the light emitted by the laser light source needs to be reflected and amplified by the reflector to project a picture with better effect on the screen, the reflector is a key factor affecting the picture quality. The angle of the reflector when it is reflecting has a great influence on the clarity of the picture. If the angle of the reflector is not good, it will...
