Brief Description of the Principle of LED UV Light Curing Machine
News 2025-12-06
Since the first emergence of LED curing technology in 2008, LED UV light curing machines have attracted increasing attention due to their cold-light curing features, including environmental friendliness, energy efficiency, high efficiency, economic viability, strong adaptability, no infrared radiation, and no ozone emission.
- Principle of LED UV Curing
The essence of LED UV curing is a “polymerization reaction of macromolecules initiated by ultraviolet light”.LED UV curing lamps emit ultraviolet light of a specific wavelength, which irradiates UV-curable materials (such as UV inks, UV coatings, and UV adhesives) containing “photoinitiators”.Through photochemical reactions, the active components in the materials are activated, enabling the materials to quickly transform from a liquid state to a solid state.This process forms a dense and wear-resistant cross-linked structure, which meets the requirements of various adhesion tests, such as resistance to nail scraping, 3M tape pulling, and alcohol wiping.
- Advantages of LEDUV Curing Lamps
In the past, ultraviolet light sources used in the printing industry were widely high-pressure mercury lamps and metal halide lamps.These devices consume high energy during operation, and only a small portion of the generated energy is utilized.Additionally, they produce toxic gases such as ozone.With the development of UV curing technology and the demand for low-carbon and environmental protection, LED UV curing lamps have become the preferred choice for curing equipment in the printing industry. They adopt LED chips, which are energy-saving and low-carbon, do not produce toxic gases, and have low operating costs.
