UV LED, or ultraviolet light-emitting diode, has emerged as a revolutionary technology in the lighting industry. With its high efficiency, long lifespan, and numerous applications, UV LED has become a popular choice for various industries. This article aims to provide an in-depth introduction to the UV LED industry, covering its history, technology, applications, and future prospects.

History of UV LED

The concept of UV LED dates back to the early 1900s when the first UV light sources were developed. However, it was not until the late 1990s that significant advancements in UV LED technology were made. In 1997, Nichia Corporation, a Japanese company, successfully developed the first high-brightness blue UV LED, which marked the beginning of the UV LED era.

Technology of UV LED

UV LED is a solid-state lighting device that emits UV light through the electroluminescence process. The device consists of a semiconductor chip, a sapphire substrate, and a phosphor layer. When an electric current passes through the semiconductor chip, it generates UV light. The phosphor layer then converts the UV light into visible light, making it suitable for various applications.

There are several types of UV LED, including UVA, UVB, and UVC LEDs. UVA LEDs emit light with a wavelength between 365 and 400 nm, UVB LEDs emit light with a wavelength between 280 and 320 nm, and UVC LEDs emit light with a wavelength between 200 and 280 nm. The different types of UV LEDs have different applications and characteristics.
