An optical device that produces multi-directional collimated beams

Abstract

The invention relates to an optical field.An optical device capable of generating collimated beams in multiple directions comprises a main body of the optical device and is characterized in that the upper end surface of the main body of the optical device is a collimating lens; the main body of the optical device is provided with at least three side walls, all of which are free curved surfaces with the same structure; the sides walls of the main body of the optical device are provided with light-reflecting surfaces, the light-reflecting directions of which face towards outside of the main body of the optical device; and the main body of the optical device is formed in such a manner that the collimating lens is fixedly connected with the side walls. The optical device capable of generating collimated beams in multiple directions has following beneficial effects: the free curved surfaces have functions of beam collimation and reflection; and by adoption of the structure, beam collimation in multiple directions and light emission in multiple directions are achieved so that systematic complexity is decreased to the maximum extent and cost of production, assembly and adjustment is reduced.

Description

technical field [0001] The invention relates to the field of optics, in particular to an optical lens. Background technique [0002] The collimating optical system can concentrate the emitted light in a small solid angle, which can greatly improve the light energy density and light utilization rate. After collimation, the local illumination ability of the beam is enhanced, and the illumination distance is increased. The collimation research is extremely useful. Broad prospects. At present, many scholars have carried out in-depth research in the field of collimating optical systems, but all of them are forward single-direction collimation. The effect is to compress the large divergence angle of the beam in the original propagation direction into a small divergence angle. There is no change, there is only one beam of collimated light after collimation. At present, there is still a lack of research on multi-directional collimation. Multi-directional collimation can be used fo...
