Prospects for the UV LED market

According to the latest release of “TrendForce LED Research (LEDinside)”, “2019 Deep UV LED Application Market Report – Sterilization, Purification and Water Treatment Market” shows that due to the global economic downturn, the target of UV LED manufacturers in 2018 failed to grow as expected. However, it still shows a steady increase, looking forward to the application market demand. In addition to the stable growth of the curing market, surface/air sterilization, static water sterilization, and mobile water sterilization are the main growth kinetic energy in the future. It is estimated that the output value of the UV LED market will reach 9.91 in 2023. Billion dollars.

According to Wu Yingjie, research manager of LEDinside, the top five UV LED manufacturers in 2017 are Seoul Viosys, LG Innotek, Nitride Semiconductors, Nichia and Epitop. In 2018, Japanese and Korean manufacturers actively cultivated the UV LED market, and the revenue rankings were reshuffled, followed by Nitride Semiconductors, Seoul Viosys, LG Innotek, Nichia and Epitop. At present, the external quantum efficiency EQE of UV-C LED is 1-4%, and the leading UV-C LED market is LG Innotek. Its external quantum efficiency can reach 4.33%. However, Stanley, DOWA, Nitride Semiconductors and Seoul Viosys can continue to improve products. effectiveness.

According to LEDinside, in 2019, a number of LED manufacturers will actively develop UV-C LED products, including Nichia, OSRAM OS, UVphotonics, Violumas, etc. to add new momentum to the development of the UV market.

UV-C LED application market three growth kinetic energy: surface / air sterilization purification, static water sterilization, and mobile water sterilization

Static water sterilization and surface sterilization (air purification, home appliances, etc.) are not demanding in time, and UV LED products are introduced at the demand side to bring added value. Market applications are quite extensive and quite a number of emerging markets have been created. Contains high-care baby products, daily contact with mobile phones, escalators, household products such as toothbrushes, toilets, cabinets, sports water bottles, thermos.

Flowing water sterilization requires fast sterilization time and high requirements on product power. LEDinisde Analysis The main domestic water purification market includes the following market opportunities, which are divided into water dispensers, kitchen hot and cold water, whole house water purification and baby products (milk machine).

In the commercial and industrial markets, the global water treatment market is about 20 billion US dollars. The market growth momentum is mainly Water Scarcity and Sustainability of Water Resources. Water treatment application market segments include Aquaculture, Commercial Buildings, Food Beverage Industry, Pools and Leisure, Life Sciences, Pharma & Biopharma, Municipal Markets for water and wastewater (Municipal Water & Wastewater), oil and gas (Oil & Gas). It mainly uses three sterilization methods, including Gravity Purifier, RO Purifier and UV Purifier. RO reverse osmosis is a widely used water purification technology that still requires UV sterilization to remove bacteria and viruses from water and degrade total organic carbon (TOC) concentrations. The water treatment market has become the most promising target market for UV-C LEDs.

In response to the demand of the water treatment market, Japanese and Korean manufacturers are actively moving towards high-power LEDs and entering the mobile water module application market. In the future, the UV-C LED market will move toward polarization: some manufacturers will enter the general consumer market, while others will enter the high-end commercial/industrial market.
