South Korean LED maker Seoul Semiconductor has agreed to license patents covering the PI-LED technology of Lumitech GmbH of Jennersdorf, Austria, which manufactures components for human-centric lighting. PI-LED technology facilitates tuning of white light through correlated color temperatures (CCTs) of 2500K to 7000K with high quality of colour rendering at consistently high efficiency, it is claimed. Based on the license agreement, Seoul Semiconductor has the right to offer tunable white components based on PI-LED technology worldwide.
"Seoul Semiconductor will apply PI-LED patent technology to the Bluetooth remote control of Smart lighting Acrich 3 and supply lighting manufacturers worldwide," says Seoul Semiconductor's chief technology officer Ki-bum Nam. "This will provide customers with a healthy and comfortable light."
Lumitech's PI-LED patents were originally filed in the mid-2000s. They refer to the manufacturing and the use of blue, red and special colour-converted mint LEDs in order to accurately provide LEDs with any chosen colour temperature and a high CRI, as well as individual colours. According to market studies, human-centric lighting will amount to 10% of the general lighting market by 2020.
