UV lamp LED, also known as ultraviolet LED, has emerged as a revolutionary technology in the field of lighting and illumination. These lamps are designed to emit ultraviolet light, which has numerous applications across various industries. In this article, we will delve into the world of UV lamp LED, exploring its history, technology, applications, and future prospects.

History of UV Lamp LED

The concept of UV lamp LED dates back to the early 20th century when scientists began exploring the use of ultraviolet light in various applications. However, it was not until the late 1990s that the first UV LED was developed by Japanese company Nichia Corporation. Since then, the technology has evolved rapidly, and UV LED lamps have become increasingly popular in various industries.

Technology of UV Lamp LED

UV lamp LED operates on the principle of semiconductor diodes. When an electric current is applied to a semiconductor material, it emits light. In the case of UV LED, the semiconductor material is specifically designed to emit ultraviolet light. The key components of a UV LED include a p-n junction, a phosphor layer, and a reflector.

• P-N Junction: The p-n junction is the core of the UV LED, where the electric current is applied. It is formed by combining a p-type semiconductor material (with an excess of holes) and an n-type semiconductor material (with an excess of electrons).
• Phosphor Layer: The phosphor layer is responsible for converting the UV light emitted by the LED into visible light. This layer is placed on top of the p-n junction and absorbs the UV light, then emits it as visible light.
• Reflector: The reflector is used to enhance the light output of the UV LED by reflecting the light back through the phosphor layer and the p-n junction.
