UV LED / IR LED into a star of the future

LED industry will also usher in the "colorful" spring (1) UV-C LED expected to increase from 2017 and 2018 into the outbreak of the growth, the overall global sterilization market value reached $ 500 billion. (2) infrared LED used in security surveillance market size in 2017 will grow to $ 30 million to 40 million.

 

The industry focused on the development of LED light source visible parts, including the backlight, lighting and so on, but by the price war, the importance of standardization specification lighting products prices have fallen sharply, resulting in LED industry is facing severe shock.

 

With visible LED market has become the Red Sea, ultraviolet (UV LED), infrared (IR LED) and other applications are being carried out is not visible, because with technical barriers to entry, many used in industrial or customized products, will price is expected from low price competition.

 

UV LED jumped Rising Star UV-A LED lead Takeoff

 

UV LED is nearly 2 to 3 years, we began to expand the application of technology, which, UV-A band of about falling 320 ~ 400nm, UV-B is about 290 ~ 320nm, UV-C band is in the 240 ~ 290nm.

 

 

 

Market potential UV-A and UV-C band maximum, if the LED assembly from the production technology point of view, the more difficult it is to do a short wavelength, compared with the current blue LED grain industry competition in many, UV LED crystal production difficult, difficult technical threshold of more than 10 times, especially in the short wave band manufacturers relatively little, not by throwing money or poaching can be resolved.

 

In addition to the grain is not easy to manufacture, packaging technology is not good to do, because UV LED encapsulating material for the destruction of more than blue LED especially shortwave materials absorb the larger, it tends to destroy the material, it is also a need to develop technology package end cooperation.

 

Prior to UV-A LED product point of view, UV-A is more similar to the current LED lighting, mainly to replace the existing UV products, including energy saving, long life and other characteristics is to promote the growth momentum replace current UV-A LED mainly used in industrial products, such as printing curing, substituted exposure process products.

 

From a cost point of view the difference UV LED, due to industrial products in the multi-kilowatt power supply designs require thousands of watts of power - and must be prolonged use, UV-A LED will significantly reduce energy consumption, and the LED has a fast switching characteristics, It helps to save power consumption.

 

In addition, traditional UV lamp to produce ozone and high temperature, so the plant must be additionally installed air-conditioning system deprived of ozone, so when applied to UV-A LED curing or exposure during manufacturing, not just to save the cost of electricity lamp , as well as the overall environment and air-conditioners and other expenses.

 

However, LED light source belongs to a single wavelength, straight sex characteristics, and is the traditional multi-wavelength UV lamp, which also increases the UV-A LED into the market threshold. When UV-A LED lamp to replace, as the original printing ink is designed to deploy in accordance with the multi-wavelength, so must first be mixed with single-wavelength light, and the light intensity, the irradiation distance, uniformity and so needs to be done as a whole to consider, the accuracy of irradiation should be very high, light angle to be small, the parallel light only about 1 to 6 degrees.

 

Thus UV-A LED and LED lighting design is totally different, not only the ability to test packaging factory, while UV-A LED system must also be made of a product, designed according to different customer needs.

 

UV-C LED is in favor of clean medical industry, as described above, UV-C LED the highest degree of difficulty, Japan or the United States only a few vendors with related technology, and are originally specializing in the field of clean chemical manufacturers.

 

According to market estimates, overall global sterilization market value reached $ 500 billion, since the principle is the use of UV-C absorption bands of DNA strand break the bacteria, the bacteria will not multiply to achieve sterilization of reproductive function. It was originally used in industrial wastewater treatment, although UV-C LED conversion efficiency is still low, only about 1 to 2%, compared to 10 to 20% lamp, UV lamp but did not do Handheld Products .

 

Thus UV-C LED lamp not replace energy-saving features, but a substantial increase in ease of use, and create new application opportunities. Future UV-C LED can be used in medical sterilization, medical analysis instrument, surface sterilization, cell phones, faucets, refrigerators, etc., the focus is not to replace the old product, but designed for ease of use were developed.

 

Recent relevant market research agency estimates, UV LED market size (grain plus package) from 2014 will be expected to expand to $ 90 million of $ 600 million in 2019, of which, UV-A LED by the impact of falling prices in recent years, growth faster, 2014 to 2016 market demand began to clear off, and that the industrial application of surface usage levels, price volatility is low, UV-C LED from 2017 and 2018 is expected to enter the growing outbreak.

 

High-power infrared LED steering the development of security, iris identification market growth look pretty

 

The infrared LED technology has been developing for some time, a wavelength of approximately falls 700 ~ 1200nm, but in recent years began to shift to high-power infrared applications, mainly used in security or market surveillance, has recently begun to support Windows 10 iris recognition later, also led to the development of related applications.

 

 

 

The current security market mainstream products, mostly falling 850 ~ 940nm, if the longer infrared wavelengths, invisible to the human eye, so far as imported products are shortwave infrared night vision surveillance, biometrics and other parts, in order to avoid causing distress to the human eye Since different wavelengths for different product areas, mainly to see how to apply the product designers.

 

According to market estimates, in 2014 the market size of the infrared LED used in safety monitoring of US $ 94 million in 2015, $ 12 million will be watching, is expected by 2017 will grow to $ 30 million to 40 million, so the next few years, security market It will be high growth areas, as long as the need night vision cameras catch in recent years, the development of the mainland market has been particularly active.

 

Regarded as a global giant Haikangwei example, in 2013 consolidated revenue of about $ 1.6 billion in 2014 increased to $ 2.7 billion in 2015 revenues of $ 4 billion to the point of view, almost 50% of the amplitude of annual growth, reflecting a very high demand for security market.

 

Infrared in the past has been used in iris recognition, but with the Internet, things flourish, we identify risks to safety also paid special attention, especially in the iris identification more secure than fingerprint recognition, iris recognition about more than 200 reconnaissance design to interpret the measuring point, fingerprint detection is only about 40 to 50 points, so the iris identification imitate ratio is very low.

 

In addition, the 2015 system supports Microsoft Windows 10, there is another recent camera module factory or brand owners eager, especially with a wavelength of 810nm-based estimated NB plants into the design may be faster pace, primarily NB application for product thickness tolerance higher, but the next, whether tablet or phone are likely to be imported.

 

Since the infrared LED manufacturing requires the use of four yuan grain machine equipment, less current industry competitors, Taiwan LED crystal grain plant to plant electrical, optical Hung mainly to the mainland market for the three optical minority have the production capacity of the company. Unlike LED lighting need to use secondary optics package in order to achieve the required optical products, infrared security control applications products tend to be made directly to the LED module light type, high-power products to how to make a small angle still having difficulty , although the recent one after the other LED manufacturers want to cut, but there are still some technical bottlenecks exist.

 

Trip LED lighting spell price old thinking no visible emphasis on technology and integration threshold

 

It is worth noting that in the past the industry jumped into the LED lighting to do when we are rushing to make standardized products, but the product is not visible to the industrialized and other special or custom applications. In UV LED, for example, if the LED industry will still UVLED product as the original LED lighting to sell, it will no doubt be in the wrong direction, even if the price is 30% cheaper, the customer is not necessarily to pay, because the whole system must be used with UV LED to end design, and even UV-C LED future is bound to move towards vertical integration route, all the way from the component to achieve the application side.

 

Since the infrared or ultraviolet LED application market in industrialized or customized products, although the overall size of the market is better lighting large, however, by high technical and operational barriers, optimistic about the future will be expected to bring new opportunities for the growth of the LED industry.
