There are several significant differences between UV LED and ordinary LED, mainly involving their emission wavelength, application field and working principle.
Difference in emission wavelength
Ordinary LED usually emits visible light (wavelength between 400 and 700 nanometers), while UV LED emits shorter wavelength ultraviolet light, usually between 100 and 400 nanometers. According to the wavelength, ultraviolet light can be further divided into three types: UV-A (near ultraviolet), UV-B (mid ultraviolet) and UV-C (far ultraviolet), and each type of UV LED has different applications.
Difference in application field
Ordinary LED is widely used in lighting, display screens, indicator lights and other fields due to its visible light characteristics. UV LED is mainly used in ultraviolet curing, ultraviolet disinfection, ultraviolet sensors and other fields. For example, UV LED is increasingly used in the disinfection of medical equipment and water treatment, because ultraviolet light has a strong killing effect on bacteria, viruses and microorganisms.
Difference in working principle
They all generate photons by exciting electrons in semiconductors through electric current, but their luminescent materials and device structures may vary to adapt to different wavelength and power requirements. UV LEDs usually require higher process technology to achieve efficient UV light output, because the wavelength of UV light is shorter and the interaction between electrons and photons is more complex.
UV LEDs differ significantly from ordinary LEDs in luminous wavelength, application areas and working principles. With the advancement of technology and the expansion of application needs, UV LEDs have broad application prospects in industry, medical treatment and life, and have become one of the important directions for future development.
