As white LED applications are becoming more widely accepted and common in the market and China makers push more price-competitive solutions, the 2015 global high-brightness LED output value is expected to only grow 7.5% on year. It is not surprising that in a market with limited growth, makers are turning to applications such as UV LEDs to increase profits. This DIGITIMES Research Special Report analyzes the developments, supply chain and makers associated with UV LED technology.
Compared with traditional mercury-based lighting products, UV LED has the following advantages over the competition: a quicker turn-on response time, more efficient energy consumption, smaller sizes and a longer lifespan. Due to these qualities, Digitimes Research estimates the technology will be the new mainstream in applications used in medical, sterilization and printing fields. In 2015 alone, the UV LED market is estimated at US$113 million, and is estimated to reach US$320 million in value by 2018.
