UVC LEDs have emerged as a revolutionary technology in the field of sterilization and disinfection, offering a more efficient and cost-effective solution compared to traditional UV-C lamps. This article aims to provide an in-depth introduction to the UVC LED industry, covering its history, applications, market trends, and future prospects.

Introduction to UVC LEDs

UVC LEDs, or Ultra-Violet-C Light Emitting Diodes, are a type of solid-state lighting that emits ultraviolet-C (UVC) light. UVC light has a wavelength range of 100 to 280 nanometers (nm), which is shorter than the wavelength of visible light. UVC light is known for its ability to destroy the DNA of microorganisms, making it an effective tool for sterilization and disinfection.

History of UVC LEDs

The development of UVC LEDs can be traced back to the early 1990s when researchers began exploring the use of semiconductor materials to generate UVC light. Initially, the focus was on developing UVC-emitting diodes using zinc selenide (ZnSe) and gallium nitride (GaN) as the semiconductor materials. However, these materials had limitations in terms of efficiency and cost. In the late 1990s, researchers at Nichia Corporation in Japan made a breakthrough by developing a high-efficiency UVC LED using GaN as the semiconductor material. This breakthrough paved the way for the commercialization of UVC LEDs and opened up new applications in the field of sterilization and disinfection.

Applications of UVC LEDs

UVC LEDs have found numerous applications in various industries, including healthcare, water purification, air purification, and food safety. Some of the key applications are: 1.
