Does the led light have ultraviolet rays?

Nowadays, people rely on lights to shine at night, and the night view of a city also relies on lights to set off the beauty of a city at night. They outline charming night scenes through different colors, shapes and sizes, and also cure every drifter who works hard outside. So, do led lights have ultraviolet rays? Let's find out.

Does the led light have ultraviolet rays?

Ultraviolet led generally refers to an LED with a luminous center wavelength below 400nm, but sometimes it is called near ultraviolet LED when the luminous wavelength is greater than 380nm, and it is called deep ultraviolet LED when it is less than 300nm. Due to the high sterilization effect of short-wavelength light, ultraviolet LED is often used to sterilize and deodorize refrigerators and household appliances. In terms of products, Niya Chemical Industry listed the varieties with emission center wavelength of 365nm-385nm, and NitrideSemiconductor listed the varieties with emission center wavelength of 355nm-375nm. The development of deep ultraviolet LED with wavelength less than 300nm is also very active.

Uv LED application

Ultraviolet rays are mainly used in biomedicine, anti-counterfeiting identification and purification (water, air, etc.). ), computer data storage and military. Moreover, with the development of technology, new applications will appear constantly, replacing the original technologies and products. Ultraviolet LED has a broad market application prospect. For example, the ultraviolet LED phototherapy instrument is a very popular medical instrument in the future, but the technology is still in the growth stage. Semiconductor deep ultraviolet light source has great application value in lighting, sterilization, medical treatment, printing, biochemical detection, high-density information storage and secure communication.

Does the led light have ultraviolet rays? Yes, that's true. At this time, led lights are very important. They are usually used on the operating table to play a role in sterilization and disinfection, giving people a sterile operating environment and reducing the concentration of bacteria in the air, thus better reducing infection for patients. The lamp not only has the function of illumination, but also has the function of sterilization.
