Sometimes, when the luminous wavelength is greater than 380 nm, it is called a near-ultraviolet LED, and when it is shorter than 300 nm, it is called a deep-ultraviolet LED. Due to the high sterilization effect of short-wavelength light, ultraviolet LEDs are commonly used for sterilization and deodorization in refrigerators and household appliances.
