What should I pay attention to when purchasing deep UV LEDs?
It shows that deep-ultraviolet LEDs featuring high-tech innovations are widely used and will become a new hot spot in global LED research and investment. Excessive investment makes the LED blue-green light market quickly turn into a red ocean, while the deep-ultraviolet LED market is still a blue ocean. How deep is this blue ocean? How do companies need to prepare to enter this blue ocean for gold rush?
Ideal alternative light source
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. The deep-ultraviolet LED with AlGaN material as the active area can cover the 210-365nm ultraviolet band. It is an ideal material for realizing deep-ultraviolet LED device products in this band. It has advantages that other traditional ultraviolet light sources cannot match.
Internet data show that the future LED market may be divided into two parts, one is visible light LEDs for general lighting, and the other is deep ultraviolet LEDs featuring high-tech innovations. At present, most of the investment in the LED industry has poured into the blue-green light field. Excessive investment has rapidly turned the LED blue and green light market into a red ocean, while the deep-ultraviolet LED market is still a blue ocean. Its broad market prospects have become a new hot spot for global LED research and investment after semiconductor lighting LEDs.
Deep-UV LEDs are widely used, including: disinfection of drinking water, air, beverages, and pharmaceutical packaging; disinfection of surgical instruments and maintenance of sterility; in the refrigerator, it can kill surviving mold spores and extend the shelf life of food. In addition to disinfection, deep ultraviolet LEDs can also perform photochemical catalysis, ink curing, and so on.
With the development of science and technology, the replacement of the original application technology and products of deep ultraviolet LED has a broad market application prospect. We compare deep ultraviolet LED with some of the products it replaces, and its advantages are obvious:
Mercury lamps: In the medical and food fields, low-pressure mercury lamps are often used for sterilization, but because mercury is easily harmful to the environment, researchers have always hoped to find environmentally friendly alternatives with excellent performance. Deep ultraviolet light is a kind of ultraviolet light with a relatively short wavelength, which has a relatively high efficiency in killing bacteria and viruses. Although the total output power of the traditional mercury lamp is large, the output light intensity per unit area is very weak, only a few percent of that of the 280 nanometer ultraviolet light emitting diode. Therefore, the deep-ultraviolet 280-nanometer band LED is more suitable for short-distance and rapid disinfection than traditional mercury lamps, and the equipment is particularly compact.
Traditional UV lamp: Due to its working principle, traditional UV lamps are very bulky compared with LEDs that belong to semiconductor products and require high-voltage ignition. In addition, although the total output power of the traditional mercury lamp is large, the output light intensity per unit area is very weak, only a few percent of that of the 280-nanometer ultraviolet light-emitting diode. Therefore, the deep-ultraviolet 280-nanometer band LED is more suitable for short-distance and rapid disinfection than traditional mercury lamps, and the equipment is particularly compact.
Mercury lamp: Compared with the mercury lamp ultraviolet light source, the deep ultraviolet LED based on aluminum gallium nitride (algan) material has the advantages of sturdiness, energy saving, long life, mercury-free and environmental protection, and is gradually infiltrating the traditional application field of mercury lamps.
Now that LED lighting is very popular, the blue light hazards have also entered people's field of vision, causing a lot of discussion in the industry. How harmful is blue light? Visual inspection is still inconclusive. So is deep ultraviolet LED harmful to the human body? A reporter from New Century LED Network learned on the Internet that the power of deep ultraviolet 280 nanometer band LEDs is very small, and its efficient sterilization depends on extremely high illuminance per unit area, rather than high power. The illuminance per unit area of the LED is inversely proportional to the square of the distance. Therefore, beyond the sterilization working distance, deep ultraviolet LED has little effect on human skin. In addition, deep ultraviolet LEDs are compact and easy to hide in design. Common glass and plastic less than 0.1 mm thick can completely absorb deep ultraviolet. Just like the lighters, knives, power sockets, etc. in daily life, the safety of properly designed UV LED products can be guaranteed as long as they are used correctly.
