With performance advantages such as safety, environmental protection, compactness, high efficiency, and low consumption, deep ultraviolet LEDs with wavelengths between 240-280 nanometers are accelerating the expansion of the application of ultraviolet rays in civil and industrial fields, and will gradually replace traditional mercury lamps.
As a major country in traditional mercury processing and manufacturing and mercury pollution, the Chinese government formally approved to join the United Nations Environment Assembly in 2016 and will gradually ban the manufacturing, import and export of mercury-added products starting in 2020. This means that in the foreseeable future, the use of The technology development and application of UV LED as a substitute for mercury lamps will usher in explosive growth.
About Deep UV LED
Ultraviolet light, as a kind of electromagnetic wave, has a wavelength smaller than visible light, ranging from 10 to 400 nanometers (nm), including: UV-V (wavelength 10-200 nanometers), UV-C (wavelength 200-280 nanometers), UV- B (wavelength 280-315 nanometers), UV-A (320-400 nanometers), among which ultraviolet rays with a wavelength less than 320 nanometers are also called "deep ultraviolet rays."
In the LED field, the current development is mainly to release UV-C. Deep ultraviolet light refers to light waves with a wavelength between 100 nanometers and 280 nanometers. Semiconductor deep ultraviolet light sources have great application value in the fields of lighting, sterilization, medical treatment, printing, biochemical testing, high-density information storage, and confidential communications.
Compared with common LEDs for lighting, deep-ultraviolet LEDs have obvious differences in materials, processes and applications. They are the most suitable solid-state ultraviolet light known for civilian use, among which UVC LEDs can emit C-band with bactericidal effect. Light. The deep ultraviolet LED sterilization and purification function has been widely used in the medical and health fields. As a new generation of ultraviolet sterilization technology, it has the characteristics of mercury-free, safe and environmentally friendly, and extensive environmental adaptability. It belongs to physical broad-spectrum sterilization and has no chemical residue characteristics. .
