Introduction to UV Curing LED Light Source

UV curing LED light source, also known as ultraviolet LED curing light, is a type of light source that emits ultraviolet light with a wavelength of 365nm to 400nm. It is widely used in various industries, such as printing, coating, adhesives, and electronics, for curing UV-curable inks, coatings, and adhesives. Compared with traditional UV curing methods, UV curing LED light sources offer numerous advantages, such as energy efficiency, environmental protection, and high curing speed.

Working Principle of UV Curing LED Light Source

The working principle of UV curing LED light source is based on the photochemical reaction of the UV light with the monomer molecules in the UV-curable material. When the UV light is exposed to the material, the monomer molecules absorb the energy from the UV light and form a polymer chain. This process is known as polymerization. After polymerization, the material will have high strength, flexibility, and durability. The UV curing LED light source typically consists of a LED chip, a phosphor layer, and an optical lens. The LED chip emits UV light, which is then converted into visible light by the phosphor layer. The optical lens focuses the light onto the surface of the material, ensuring efficient and uniform curing.
