The expected increase in the UV LED demand and the overall rise in the LED industry are the primary aspects fuelling the growth of the global market. According to the BIS Research report titled, ‘Global Ultraviolet-LED Market- Analysis and Forecast (2017-2023)’ the global UV LED market is expected to reach $1.2 billion by the end of 2023, registering a CAGR rate of 28.4% from 2017 to 2023. The market players are coming up with new product launch as a preferred strategy to stay in the competitive market and to cater to the growing need of advanced UV LED system. Some of the key market players are Philips Lighting, Honle group, and Phoseon Technology, among others.
Recently, On 12th Feb 2018, the two prominent market players AkzoNobel and Royal Philips are teaming up to develop an economically viable solution that will be used for underwater surfaces to reduce fouling growth. On behalf of this, Klaas Kruithof, Chief Technology Officer of Akzo Nobel said, “We actively look for complementary technologies and partners to innovate with. In this case, the combined capabilities and technology of Royal Philips and AkzoNobel will enable us to accelerate the realization of this transformative innovation, which we intend to initially market ourselves and consider licensing out to third parties for large-scale adoption.”1
On 9th Feb 2018, Dowa Holding subsidiary Dowa Electronic Materials Co. Ltd. of Tokyo, Japan, announced that it has developed a deep ultraviolet- LED chip, which it claims to be the world’s highest output power of 90Mw, with a peak wavelength of 310nm and dimensions of 1mm * 1mm. For the wavelength of 310nm, combining this technology and fine-structured sapphire substrate developed by Oji Holdings Corporation, Dowa proceeded to improve luminous efficiency, enabling a 20 % higher output power compared to the current products. These lights have replaced the conventional mercury and excimer lamps and are extensively used for curing and skin therapy. Along with its applications such as long-life time and power-saving, it is expected that it will find a significant place in the global market soon.2
Earlier, on 28th Nov 2017, LG Innotek announced that it has developed the world’s first germicidal UV-C-LED with an output power of 100Mw.The device is a semiconductor light source designed to emit ultraviolet rays with a wavelength of 200nm to 280 nm. It requires no chemical treatment and can be used in home appliances such as water purifiers, air cleaners and in air-conditioning systems of buildings and automobiles.3
According to the analyst, “the market growth is primarily driven by the reduced prices of UV LEDs, and increased adaptability, efficiency and enhanced lifespan of these light as compared to the traditional LEDs. Further, the development of UV LEDs with the help of next-generation substrates and the emerging application areas such as disinfection and purification, among others, are some of the factors that will contribute to the growth of the market in the future.”
