History of UV LED Lamps

The concept of UV LED lamps dates back to the early 20th century when the first UV lamps were developed. However, it was not until the late 1990s that significant advancements in LED technology led to the development of UV LED lamps. The introduction of blue LEDs in the late 1990s paved the way for the development of UV LEDs, as blue light is essential for the generation of UV light. Since then, the UV LED lamp industry has grown exponentially, driven by technological innovations and increasing demand in various applications.

Technology of UV LED Lamps

UV LED lamps operate on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The semiconductor material used in UV LEDs is typically gallium nitride (GaN), which emits UV light when excited by an electric current. The key advantages of UV LED technology include high efficiency, long lifespan, and low power consumption. UV LED lamps are available in various wavelengths, ranging from UVA (320-400 nm) to UVB (280-320 nm) and UVC (100-280 nm). Each wavelength has specific applications, with UVC being particularly effective for disinfection and sterilization.
