UV lamp LED, also known as ultraviolet LED, has become a significant trend in the lighting industry in recent years. With its high efficiency, long lifespan, and environmental protection characteristics, UV lamp LED has been widely used in various fields such as medical treatment, printing, and disinfection. This article will introduce the industry of UV lamp LED, including its working principle, types, applications, and future development prospects.

Working Principle of UV Lamp LED

The working principle of UV lamp LED is based on the photoelectric effect. When a forward voltage is applied to the LED, electrons and holes are generated in the p-n junction, which recombine in the active layer. During the recombination process, part of the energy is released in the form of ultraviolet light. The wavelength of UV light produced by UV lamp LED is generally between 200nm and 400nm, which can be divided into UVA, UVB, and UVC according to the wavelength range.

Types of UV Lamp LED

UV lamp LED can be divided into several types according to the emission spectrum and application fields:

1. UVA LED: The wavelength range of UVA LED is between 320nm and 400nm. It is widely used in the field of printing, such as curing of inks and coatings.

2. UVB LED: The wavelength range of UVB LED is between 280nm and 320nm. It is mainly used in the field of medical treatment, such as sterilization and disinfection of wounds.

3. UVC LED: The wavelength range of UVC LED is between 200nm and 280nm. It has strong sterilization and disinfection effects and is widely used in the field of air and water purification.
