On March 7th, according to foreign media reports, LG Innotek, a subsidiary of LG, announced on Wednesday that its UV-emitting diode technology will focus on the global water treatment market, especially in the Chinese market.
The company said it has developed a 150-mV UV LED chip this year and will increase its power to 200 mW next year.
LG Innotek is well known as a supplier of smartphone camera modules and is a major supplier of Apple's iPhone dual camera.
Currently, 2-10 mW of ultraviolet light is widely used in water, air purifiers and other household appliances. This powerful UV over 100 mW will be used for sterilization of large industrial facilities such as water treatment, hospital hygiene arrangements and large manufacturing facilities.
Park Jong-seok, CEO of LG Innotek, said, “We have gained a variety of contacts in China. In daily life, more and more places will use UV LEDs, for example, for maintaining public places. Escalator handrail."
It is understood that in July 2017, LG Innotek announced the launch of the world's first "Handrail UV LED Sterilizer" that uses the powerful light of UV (ultraviolet rays) LEDs to perfectly remove bacteria from the escalator's handrails. LG Innotet's UV LED technology is at the heart of it.
In addition, in March 2017, the LG Innopo State Office began mass production of the "UV LED Module for Water Purifier Faucet Sterilization". It is reported that in the new model of LG Electronics drinking water purifier "PuriCare Slim Updown", the production module has been installed.
The UV LED module uses UV light to directly sterilize the water inside the faucet. The product is 1.5 cm long and 3.7 cm wide and can be installed in a small space inside the water purifier. In actual use, the product is UV-irradiated for 5 minutes with this product, which can kill 99.98% of bacteria at 278 nm (nm) wavelength.
In addition, the LG Innote UV LED module does not contain chemicals or heavy metals, and is simply sterilized by using ultraviolet rays, so it is harmless to the human body. Unlike mercury UV lamps, UV LEDs are not at risk of breakage, so they can be used with greater confidence.
With the power improvement and technical advancement of ultraviolet LEDs, the lower-power ultraviolet mercury lamps have been gradually replaced by the advantages of long life and small volume in the market.
After the international ban on mercury (mercury), the Minamata Convention on Mercury, signed in 2013, there are only two years left until 2020, when mercury is completely banned.
In Japan, China, the European Union and other markets, in the field of ultraviolet lamps for household and industrial use, UV LEDs are needed to replace these UV mercury tubes, and it has also accelerated the take-off of the UV LED market around the world.
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%.
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, Jingyuan Optoelectronics, Seoul Semiconductor, Hongli Zhihui, Guoxing Optoelectronics, Ruifeng Optoelectronics, etc. product.
Li Bingjie, chairman of Jingyuan Optoelectronics, said, "The gross profit margin of other mature LED markets is no longer the same. We estimate that more and more manufacturers will enter the UV LED market driven by high profits."
It is worth mentioning that Hongli Bingyi, a subsidiary of Hongli Zhihui Group, released the first series of all-inorganic package UV LED deep ultraviolet CMH6868, CMH6060 and CMH4545 in China last year.
"In essence, foreign UV LEDs currently have technological advantages, and Chinese companies are relatively in a weak position. However, Chinese companies have strong learning ability, and in technology, there will be 'peep-chasing-peer-peevering' like white LEDs. From the market side, the initiative is in the hands of Chinese companies, and there are enough opportunities to try.†Hongli Bingyi, general manager Wu Gan finally mentioned.
