According to a study in TrendForce LED (LEDinside) newly released "2019 deep uv LED application market report, sterilization, purification and water treatment market" shows affected by the global recession, uv LED manufacturers in 2018 revenue targets not as expected growth of outbreak, but still steady increase, the outlook for application of market demand, in addition to curing market stable growth, surface/air sterilization purification, static water sterilization, flowing water sterilization for the future the main growth momentum, The uv LED market is estimated to be worth $991 million in 2023.
According to analysis of LEDinside research manager wu yingjie, the top five ultraviolet LED manufacturers in 2017 are Seoul Viosys, LG Innotek, Nitride Semiconductors, Nichia and Epitop. In 2018, Japanese and Korean manufacturers actively cultivate the ultraviolet LED market and reshuffle the revenue ranking, in order of Nitride Semiconductors, Seoul Viosys, LG Innotek, Nichia and Epitop. At present, the EQE of uv-c LED external quantum efficiency is 1-4% on average, and the market leader of uv-c is LG Innotek, whose external quantum efficiency can reach 4.33%. However, it can be seen that Stanley, DOWA, Nitride Semiconductors and Seoul Viosys continue to improve product efficiency.

According to LEDinside's observation, in 2019, a number of LED manufacturers will actively develop uv-c LED products, including Nichia, OSRAM OS, UVphotonics, Violumas and other new drivers for the development of the UV market.
Uv-c LED application market three growth momentum: surface/air sterilization purification, still water sterilization, and flow water sterilization
