It is reported that the "Minamita Convention on Mercury" signed by more than 90 countries around the world has officially entered into force in August 2017. The treaty bans the production and import and export of various products containing "mercury" from 2020. .
Since the energy-saving bulb contains mercury, and the LED bulb has a small price difference with the power-saving bulb, it is expected that LED lighting will be replaced in a large amount next year, and the demand for LED lamps can complement the newly added capacity. Zhang Shixian, the person in charge of Jingyuan Optoelectronics, said that after the implementation of the Minamata Convention, more countries will sign up in the future, which will increase to 146 countries. It is estimated that LED lighting will double by 2020.
Among them, UV LED as a new journey of LED, is considered as one of the next generation of light sources, has been highly concerned by the world in the past two years, coupled with the promotion of waterlogging conventions, power saving and other policies, domestic and foreign companies began to accelerate the layout. The UV LED market is about to break out.
High gross profit is attractive, domestic and foreign manufacturers compete for layout
As we all know, the LED general lighting market experienced a major reshuffle in 2016. After entering 2017, the focus of major companies began to shift to the sub-segment. Under the background of oversupply and continuous low gross profit in the LED general lighting industry, UV LED is a high-margin market and attracts many domestic and foreign enterprises.
According to Gaogong LED observation, in the past two years, well-known domestic and foreign manufacturers are vying to switch to the UV LED market, such as Nichia, Seoul Semiconductor, LG Innote, Mulinsen, Hongli Zhihui, Guoxing Optoelectronics, Ruifeng Optoelectronics, etc. Has launched related products.
In the view of Li Bingjie, chairman of Jingyuan Optoelectronics, "the gross profit margin of other mature LED markets is no longer the same. It is estimated that more and more manufacturers will enter the UV LED market driven by high profits."
Today, the UV LED market is welcoming a new round of growth. On the one hand, the UV LED technology is constantly maturing, and on the other hand, the market demand for UV LED-based applications is becoming large-scale.
According to the High-tech Research Institute LED Research Institute (GGII), the global UV LED market will exceed $1 billion by 2020, with a compound annual growth rate of 44.3%.
It is worth mentioning that, like the traditional general lighting market, the UV LED demand market is also mainly concentrated in China.
"At present, foreign manufacturers regard China as the main market, while domestic manufacturers' products are mainly used for domestic sales. Therefore, Chinese manufacturers have more advantages in terms of understanding of the market and matching of customers." Jingneng Optoelectronics UV LED Market Director Tang Wenjun said.
UV curing is difficult to explode in a short time?
It is undeniable that with the increasing attention of UV LED curing technology, UV LED light sources have been gradually replaced by conventional mercury light sources in many applications.
According to Tang Wenjun, "The market share of UV LEDs will increase rapidly this year. It is expected that the overall market will soon explode. In addition, it is believed that UV LEDs will be the first to break out in the fields of industrial light curing, exposure machines, and fluorescent agents."
Yan Xiaoming, vice president and CTO of Ruifeng Optoelectronics, also believes that “printing, manicure, and plant lighting applications have relatively low thresholds, limited chip resources, and efficiency can meet application level requirements through some integrated methods. This will be the first to break out. Market."
From the chip technology point of view, UVA LED (315-405nm) has begun to mature (but there are also many problems, such as the product's anti-static ability, low-band 365nm reliability is relatively poor); from the packaging technology point of view, UVA LEDs have relatively low requirements for packaging (except for industrial grade markets).
Hongli Bingyi, general manager Wu Gan said frankly, "At present, everyone expects a high incidence of UV curing, but most of UV curing is applied to the industrial market, which is very demanding on the system."
Indeed, UV curing applications require entrants to have a good understanding of the LED environment, interference with ink (including varnish), power drive, machine operation (current fluctuations, electromagnetic vibration, machine operation thermal disturbances, etc.), oil and gas environment, printing materials , operating speed, cooling system, etc. should have sufficient understanding and corresponding solutions.
"So, I think that China's industrial-grade photocuring is difficult to explode in a short period of time. However, in some areas of photocuring, such as the simple system of ink, paint, paint light curing (especially handheld light curing field) will break out in advance. "Wu Gan finally mentioned.
What do domestic and foreign companies do in UV LED?
In August 2017, RayVio, an advanced public health and hygiene company, signed a new distribution agreement, and its UVB and UVC LEDs will be shipped globally through Digi-Key Electronics, a global electronic component distributor.

In May 2017, HexaTech Inc. announced that it has signed two strategic agreements with OSRAM Opto Semiconductors. HexaTech CEO John Goehrke said: We believe that this partnership with OSRAM has created a real win-win situation for both parties. By licensing the company's technology, not only can OSRAM use HexaTech's materials to accelerate the development of its UV-C LED components, but HexaTech can focus on the company's core competencies and supply world-class AlN substrates.
Among them, in the UV products, LED Engin provides powerful UV LEDs for industrial applications such as printing, curing and dental markets.
