Blue Ocean: exploring the deep UV LED how deep water?

Introduction

Studies have shown that 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, so this piece of blue water, how deep? To enter this piece of blue ocean gold, companies need to prepare?

Ideal alternative light source

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.. Using AlGaN material as the ultraviolet light emitting wavelength of the active region of deep UV LED can cover 210-365nm, is an ideal material for the realization of the band deep UV LED devices, with other traditional UV light incomparable advantages.

Internet data show that the future of the LED market may be divided into two parts, part of the general lighting for the visible light LED, and the other is a high-tech innovation featuring deep UV LED. Currently, most of the investment in the LED industry has been flooded into the field of blue-green. 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. In addition to disinfection, deep UV LED can also be photochemical catalysis, ink curing, etc..

With the development of science and technology, deep UV LED replace the original application technology and products have a broad market prospects, we will be deep UV LED and some of its products, compared with the obvious advantages:

Mercury lamp: in the field of medical and food, often use low pressure mercury lamp sterilization, but Mercury is easy to cause harm to the environment, so researchers have been looking for a good performance of environmentally friendly alternatives. Deep UV is a relatively short wavelength of ultraviolet light, killing bacteria and viruses are more efficient. 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 hundred of the 280 nm ultraviolet light emitting diodes. Therefore, the deep ultraviolet 280 nm band LED is more suitable for fast disinfection than the traditional mercury lamp, and the equipment is very compact.

Traditional UV lamp: the traditional ultraviolet light because of its working principle needs, and the semiconductor products belong to the LED, the volume is very large, the need for high pressure glow. 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 hundred of the 280 nm ultraviolet light-emitting diodes. Therefore, the deep ultraviolet 280 nm band LED is more suitable for fast disinfection than the traditional mercury lamp, and the equipment is very compact.

Mercury lamp: mercury lamp UV light source, based on aluminum nitride (AlGaN) material of deep UV LED with solid, energy saving, long life, mercury free environmental protection and other advantages, is gradually infiltrated into the traditional application of mercury lamp.

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 much is the blue light?. So deep UV LED to the human body is hurt? The new century LED network reporter on the Internet to understand, 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 unit area illumination is inversely proportional to the square of the distance. Therefore, in addition to the working distance, the effect of deep UV LED on human skin is negligible. In addition, deep UV LED compact size, easy to hide design, less than 0.1 mm thick ordinary glass and plastic can completely absorb the deep uv. As in the daily life of lighters, knives, power sockets, etc., as long as the correct use of the design of a reasonable UV LED supplies is completely safe.

The industry has invested

Many companies have discovered this new blue ocean and put in, and the formation of commercialization in this area. According to relevant statistics, in 2012 the world's deep UV LED potential application market size of about $6 billion. The United States SECT company has launched a life more than 10000 hours of deep ultraviolet (UV) as early as 2011 LED products; Japan U-VIX committed to UV light source application development, its 2010 sales of only $2 million, while the 2011 sales will exceed $10 million; Qingdao Jason completion by the end of 2010 China's first 280 nm wavelength deep UV LED production line, R & D and production with independent innovation of intellectual property of deep UV LED products, they developed the first domestic deep UV LED epitaxial growth of production equipment, the equipment has been breaking the monopoly of foreign companies; by the end of 2011, three optical and CRYSTALISINC partners (USA) launched at that time the world's highest brightness of the deep UV LED chip......

In addition there are many enterprises have invested in the blue ocean, the global research institutions also started the research in this field, it is understood that the leading research in the deep ultraviolet of the United States, but in recent years Japan has been beyond China; Taiwan and South Korea started relatively late, but also made some progress in this field in China; the field has developed quickly in recent years,.
