Abstract

The invention relates to a laser module of a point light source. The laser module comprises a casing, and a laser diode, a driving circuit, a lens system and a lens cone which are arranged in the casing, wherein the laser diode is arranged at the back end of the lens cone, and electrically connected with the driving circuit; the lens system is arranged at the front end of the lens cone, and is a single-chip optical collimating lens. The laser module of the point light source has the advantages of simple structure, convenience for processing, assembly and maintenance, good stability, round and normal imaging light spots and excellent viewable effect.

Description

technical field [0001] The invention relates to the technical field of optical equipment, in particular to a point source laser module. Background technique [0002] A point light source is a light source idealized as a particle that emits light in all directions. Existing point source laser modules have many different types and debugging methods according to customer needs. There are many debugging methods, cumbersome mechanisms, complicated connection relationships, difficult processing and assembly, and high cost. The roundness of point spot and point spot imaging is not high. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a point source laser module with simple structure, convenient processing, assembly and maintenance, good stability, round imaging spot and excellent visual effect. [0004] The technical solution to realize the object of the present invention is: a point source laser mo...
