Technical Field
The invention relates to the technical field of laser projectors, in particular to a reflector adjustable device fixed in a projector.
Background
The optical path system plays an important role in laser projection, when a laser emits light, high-brightness parallel light needs to be generated through refraction of lenses with different curvatures, and in order to save the space of the optical path, a reflector needs to be used for changing the direction of the optical path in the process.
The reflecting mirror realizes the conversion of different angles or directions of the light path by utilizing the law of reflection, and in practical application, certain deviation exists in the position of the reflecting mirror due to errors brought by aspects of light path design, machining process, assembly process and the like. In the optical path system, if the position of the reflecting mirror is shifted or there is a slight deviation between the angle of the reflecting mirror and the optical path and the original design value, the inside of the whole projector and the output optical path thereof are far from the original required optical path. Therefore, the position of each reflector and the light path must be accurate, otherwise the intensity of the final output light source is affected, so that the brightness is low, the brightness is not uniform, the power consumption of the whole projector is overlarge, and the service life of the projector product is greatly shortened. Therefore, further adjustment of the mirrors in the optical system is necessary, especially for the mirrors in some critical positions. However, in the prior art, it is difficult to adjust the mirror fixed in the projector.
