Abstract

The utility model relates to a novel spot-light-source laser module. The spot-light-source laser module comprises a housing, and an optical component, a lighting source and a driving circuit which are arranged inside the housing; wherein the optical component is arranged at a front end of the housing; the lighting source and the driving circuit are arranged at a rear end of the housing, and the lighting source is electrically connected with the driving circuit; the housing includes a front-end housing and a rear-end housing; and the front-end housing and the rear-end housing are in plug connection. According to the utility model, an uniquely designed structure of a laser module metalwork housing is adopted, and an one-piece housing structure is divided into a front half part and a rear half part based on the requirements of the focus imaging of an optical alignment system, such that the optical component required for optical focus imaging is arranged in the front half part, a lighting source, i.e., a laser light-emitting diode, is embedded into the rear half part, and the front and rear half parts are used with special focus and connection technologies so as to meet the technical requirements of low-end laser line and spot modules, improving the production efficiency and reducing the production cost.

Description

A kind of novel point light source laser module

Technical field

The utility model relates to the optical devices technologies field, particularly relates to a kind of novel point light source laser module.

Background technology

Existing point-source of light laser module has a lot of different kind and adjustment methods according to client's demand, and adjustment method is numerous, and mechanism is loaded down with trivial details, and annexation is complicated, processing and assembling difficulty, and cost is higher.

The utility model content

The purpose of this utility model is to overcome the defective that prior art exists, and a kind of simple, easy to operate novel point light source laser module that assembles is provided.

The technical scheme that realizes the utility model purpose is: a kind of novel point light source laser module, the optical component, illuminating source and the drive circuit that comprise shell and be arranged on enclosure; Described optical component is arranged on the front end of shell; Described illuminating source and drive circuit are arranged on outer casing back, and illuminating source and drive circuit electric connection; Described shell comprises front-end case and rear end housing; Be grafting between described front-end case and the rear end housing.
