Light-emitting diode (LED) manufacturers are now looking to develop niche application markets that can provide higher margins as the price competition in the LED lighting market has become too difficult for them. Among these niche application markets, ultraviolet (UV) LED has attracted investments from many manufacturers because of its enormous market value. The UV LED market has much higher technological barrier to entry, so prices of its products are several tens of times greater than those of the general LED products. LEDinside, a division of TrendForce, states that the global UV LED market in 2015 is estimated at US$122 million, which is around the same level as in 2014, in its 2015 Global LED Industry Supply and Demand Database Report. The absence of noticeable growth in the market value this year is mainly attributed to the rapid decline in UV-A LED prices (UV-A spectrum is between 320~400nm in wavelength).
“On account of the sharp price decline in this year’s UV-A LED market, LED manufacturers that focus on UV applications will step up efforts in technological research and development so that they can advance into the UV-C LED (under 280nm in wavelength) market in the next two years,” said Joanne Wu, LEDinside assistant research manager. “Since UV LED’s ‘blue ocean’ market is based on technological innovations and customizable product designs, manufacturers can expect wider applications to emerge, such as DUV SMS communication. By 2020, the market value of UV LED is projected to reach US$356 million.”
