Preparation method of laser array driving module

Abstract

The invention provides a preparation method of a laser array driving module. The preparation method comprises the following steps: selecting different types of lasers and the number of the lasers according to the brightness requirement of a system; selecting a direct-current constant-current source module according to the characteristics of the laser; and the lasers are grouped according to the output voltage of the selected direct current constant current source module, and the lasers in each group are connected in series. The total voltage required by the lasers is obtained according to the driving voltage of one laser and the number of the lasers in the group, and the total voltage is smaller than the output voltage of the direct-current constant-current module; selecting a direct current constant current source module matched with the laser driving mode; laser modules are connected in series into a loop of a circuit to form basic constant-current driving units, and a plurality of basic constant-current driving units are connected in parallel to form a complete laser array driving module. The invention has the advantages that: for an electronic product taking the laser array as a light source, the driving of the laser array can be flexibly configured, the defects in the prior art are overcome, and the product design requirement is quickly and efficiently met.

Description

Technical field [0001] The present invention relates to the field of electronic product design, and more particularly to a method of preparing a laser array drive module. Background technique [0002] The manufacturing method of the laser array drive of the prior art implementation is typically customized according to the actual light source, and the custom content comprises the number ratio of triolysis, the volume of the light source, the applicable voltage. The laser array drive module customized according to the above needs is not only a high cost, but also is not flexible enough, and cannot be utilized by transformation, resulting in a waste of resources, high cost, poor compatibility. In addition, due to the difficulty of modular design, there is a problem that the production cycle is long. Inventive content [0003] The present invention provides a laser array drive module preparation method to solve the laser array drive module in the prior art requires customization, an...
