UV lamp LED, or ultraviolet LED lamp, has become an indispensable part of modern life. With the continuous development of science and technology, UV lamp LED has been widely used in various fields, such as medical treatment, food safety, environmental protection, and printing. This article will introduce the industry of UV lamp LED, including its development history, working principle, application fields, and future development prospects.

Development History of UV Lamp LED

The development of UV lamp LED dates back to the early 20th century. In 1903, the German physicist Philipp Lenard discovered that electrons could produce ultraviolet light when they struck a metal target. This discovery laid the foundation for the development of UV lamps. In the 1960s, the development of semiconductor technology led to the emergence of UV LED lamps. In the 1990s, with the continuous optimization of LED technology, UV LED lamps began to be widely used in various fields.

Working Principle of UV Lamp LED

The working principle of UV lamp LED is based on the photoelectric effect. When the forward voltage is applied to the LED chip, electrons and holes are generated in the semiconductor material. Under the action of electric field, electrons and holes recombine, releasing energy in the form of photons. The energy of photons determines the wavelength of the light emitted, and the wavelength of UV light is in the range of 10-400nm.
