Study on deep UV and UVLED

Deep UV LED has always been the focus of UVLED research and development, because the band is lower, the greater the difficulty of production. But 280nm UVLED has a huge market, people have been seeking the market popularization.

Deep UV LED application to high-tech innovation as the characteristics of widely, will become the new hot spot of research and investment of global LED, excessive inputs to the blue and green LED market quickly turned into the Red Sea, and deep UV LED market is still a blue ocean.

Deep UV refers to a wavelength of 100 nm to 280 nm wavelength semiconductor, deep UV light has significant application value in lighting, sterilization, medical, printing, biochemical detection, high density information storage and security communication etc.. The emission wavelength of deep UV LED to ultraviolet band covering 210-365nm, is an ideal material for the realization of the band deep UV LED devices, with other traditional UV light incomparable advantages.

The future LED market can be divided into two parts, one part is the visible LED for general lighting, the other is to high-tech innovation as the characteristics of deep UV LED. At present, most of the LED industry investment into the blue and green fields. Over the blue and green LED market quickly into the Red Sea, and deep UV LED market is still a blue ocean, the broad market prospects, after becoming the semiconductor lighting LED, the new focus of research and investment in global led.

The application of deep UV LED is very extensive, including: drinking water disinfection, air, beverage, pharmaceutical packaging; surgical instruments sterilization and aseptic condition to maintain; in the refrigerator, killing the survival of spores, prolong the preservation period of more food. Besides the disinfection effect, deep UV LED is also capable of photochemical catalysis, ink curing etc..

With the development of science and technology, deep UV LED to replace the original technology and products have a broad market prospect, we will be part of the product of deep UV LED and its alternative comparison, its advantage is obvious:

In medical and food industry, often using low-pressure mercury lamp sterilization, but because Mercury is likely to cause harm to the environment, so the researchers wanted to find excellent green alternatives. Deep UV is a relatively short wavelength ultraviolet radiation efficiency of bacteria and viruses is relatively high. Although the total output power of the traditional mercury lamp, the output light intensity per unit area is very weak, one of the hundreds of only 280 nm ultraviolet light emitting diode. Therefore, deep ultraviolet at 280 nm LED is more suitable for short distance rapid disinfection than traditional mercury lamp, and particularly small volume of equipment.

The traditional UV light due to its working principle, compared with semiconductor products belonging to LED, a very large volume, high-pressure glow. In addition, although the total output power of the traditional mercury lamp, the output light intensity per unit area is very weak, one of the hundreds of only 280 nm ultraviolet light emitting diode. Therefore, deep ultraviolet at 280 nm LED is more suitable for short distance rapid disinfection than traditional mercury lamp, and particularly small volume of equipment.

In the LED lighting in the limelight now, a blue light hazard has entered people's field of vision, caused a lot of debate in the industry. How big is the blue light hazard is unclear visual?. So deep UV LED to the human body is hurt? Deep ultraviolet at 280 nm LED power is very small, its high bactericidal effects on the unit area of high intensity, high power and not. The LED illumination unit area with distance is inversely proportional to the square. Therefore, in addition to sterilization work distance, very little effect of deep UV LED on human skin. In addition, deep UV LED compact, easy to hide, less than 0.1 mm thick ordinary glass and plastics can be completely absorbed in deep ultraviolet. Just like the lighter, in daily life, such as cutting power socket, as long as the correct use of safety, reasonable design of UV LED products can be completely ensured.

People in developing the LED lighting at the same time, also in the application research of deep UV led. And in some areas has made great progress. In curing, the popularity of UVLED is very high. Now people in the deep UV LED on the one hand, has begun to increase the investment.
