UV LED high threshold is difficult to block Red additional value is the fuse

China [LED] - "13th Five-Year" planning the upcoming landing, LED lighting products prices no longer industry subsidies, sold on the pounds, invalid capacity to accelerate the exit, enterprise integration of large, medium and small enterprises very careful, new blue ocean is almost a hot rush. When the UVLED first appeared in the LED industry as a new blue ocean view, the number of enterprises are few, now when standing in the new blue sea of people, is no longer to see the sea, but the sea began, the future may also be a repeat of this piece of blue ocean blue LED Red Sea road.

Maybe UVLED is the Red Sea early but as the industry, exaggeration, along the way, from the international giant Seoul semiconductor company acquired the SETi up to 50% of the shares, to the domestic harmony photoelectric 109 million acquisition of Qingdao Jason 85.61% shares, then to branch and only 60 million A round of financing and so on, have the force of UVLED. At a time when compared to the original UVLED, has begun to attract a lot of capital injection.

No matter from 08 years to 14 years, only about 10 of the more than and 50 growth rate, single capital changes from 2015 UVLED field and participate in blue big coffee from PHILPS and LG, we can see that the UVLED market of blue is not imagined so blue, the future of UV LED market more revenue depends on its added value.

The threshold is not high bottleneck deep yield

Although the UV market prospects, but the threshold is high. Honglitronic also believes that ultraviolet LED not only the high technical threshold, and special raw materials, packaging technology, different from the white lighting, the need for special programs to verify.

Perfect technology's Jason electric chairman Zhang Guohua said, deep UV LED threshold is very high, mainly in three parts, the first is the UV semiconductor materials is second, third is the epitaxial growth, chip preparation and chip package.

In addition, UVLED itself still has a certain bottleneck. Because of its external quantum efficiency of a few percentage points of UVC to UVA (UV-A band) and near UV 40 ~ 50%, while the development of high efficiency chip research and development or will become the key to achieve growth in the UV LED market.

In other words, the efficiency of UV LED will directly affect the penetration rate of UVLED. This in the future to promote the UVLED market growth in the field of purification and disinfection, because the UVC is not enough efficiency, and in the application of the popular obstacles.

If we want to improve the external quantum efficiency, LED manufacturers have to improve a number of parameters related to efficiency, accelerate the extent of technology development.

It is necessary to improve the internal quantum efficiency, quantum injection efficiency and light extraction efficiency. In other words, the LED blue chip flip chip structure and optoelectronic technology, such as improving the efficiency of the direct use of UV LED. But the existence of UV LED from the In/AlGaN epitaxial layer, so the need to promote research and development from the substrate and crystal growth level, specifically to solve this problem.

In this regard, Jason electric chairman Zhang Guohua said, because the UV LED epitaxial layer growth than the common blue extension is much more complicated, the traditional MOCVD is not suitable for its growth, therefore need to understand the growth mechanism of MOCVD enterprise, to custom equipment, or independent research and development of MOCVD equipment, this is Jason has been leading domestic reasons.

In addition to the light output power is low, due to the low efficiency of the UV LED because of the presence of ultraviolet radiation to accelerate the oxidation of organic materials, thermal stress, moisture stress and impurity into three aspects, the current in the resin package there is a further problem.

Although some foreign manufacturers introduced the use of glass packaging UV LED, but the package structure always cannot avoid using organic filler material or organic bond material, only through to minimize the use of organic packaging materials, thereby reducing due to the attenuation caused by heat stress problems, the failure problem, so seeking a stable package reliable becomes very urgent.

When such a high threshold, LED enterprises want Fengeng is not easy. So in this capital s LED field, companies want to expand the blue ocean is no longer spend time with their own R & D, but to find a suitable object and then mergers and acquisitions into their arms. But the face has the core technology of enterprise resource scarce areas, to acquire capital is also facing some difficulties, it had to turn to the application of the core technology of the.

Value added penetration can be the main battlefield of the diversified application market

UV curing was first introduced in 1960s, and today's manufacturers are using this technology in a variety of areas - from print to automotive headlamps and more. It is reported that at this stage 90% UV LED application market is mainly concentrated in the 365-405nm band, mostly used for curing, and UV curing market continues to grow. Because it replaces the water and solvent type in order to improve the productivity of the heating drying process, better quality and performance, and environmental benefits.

Substantial growth in the market for UVLED curing, mainly due to the technical progress made on UVLED equipment, such as the gradual evolution from mercury lamp to UVLED lamp. According to a survey agency reports mentioned, due to the expansion of the application of the solidification, the overall UV LED market grew from $20 million in 2008 to $90 million in 2014, a compound annual growth rate of up to 28.5%.

In addition to UV LED curing will continue to occupy the ink, adhesives and coatings and other industries, the sterilization market is also growing, but also increasingly used in the field of purification. Many companies are committed to the purification of UVLED applications, technically
