265nm LED: A Powerful Disinfection Technology by Tianhui UV LED


Disinfection techniques have been evolving forever, now a powerful contender has emerged: 265nm ultraviolet light-emitting diodes (LEDs). These tiny marvels of technology offer a potent and versatile solution for eliminating harmful microorganisms, creating cleaner and safer environments. So, let's take a ride and explore the world of 265nm LEDs, their properties, advantages, applications, and safety considerations. We will also specifically focus on the expertise and offerings of Tianhui UV LED, a leading manufacturer in this field.

Understanding UVC Light and 265nm Wavelength

Ultraviolet (UV) light is a type of electromagnetic radiation invisible to the human eye. It occupies a specific region on the electromagnetic spectrum, situated just beyond the violet end of visible light. Unlike visible light, which interacts with our photoreceptor cells in the retina, UV LED interacts with matter at the atomic and molecular level. This interaction varies depending on the specific wavelength of the UV light.

The UV spectrum itself is further divided into three subcategories based on wavelength: UVA, UVB, and UVC.

UVA (315nm - 400nm)

This type of UV light has the longest wavelength within the UV spectrum and penetrates the deepest into human skin. While UVA rays contribute to tanning and premature skin aging, they are generally considered less harmful compared to UVB and UVC rays. 

UVB (280nm - 315nm): 

This band of UV LED is responsible for sunburns and plays a role in vitamin D synthesis in the human body. However, prolonged exposure to UVB rays can increase the risk of skin cancer.

UVC (200nm - 280nm): 

UVC light possesses the shortest wavelength within the UV spectrum and is consequently the most energetic. It is this very property that makes UVC light germicidal. When UVC photons come into contact with microorganisms like bacteria, viruses, and fungi, they are readily absorbed by the microbial DNA and RNA. This absorption disrupts the genetic material of the microorganism, rendering it incapable of reproduction and ultimately eliminating it.

The effectiveness of UVC light for disinfection relies on the wavelength. Within the UVC spectrum, the 265nm wavelength falls within the prime germicidal zone. At this specific wavelength, the energy carried by the UV photons is ideally suited for absorption by the microbial DNA, maximizing the germicidal effect. This sweet spot between wavelength and DNA absorption makes 265nm UV Led a particularly powerful tool for disinfection applications.
