HKU Chair of Power Electronics Professor Ron Hui led sustainable lighting systems research brings new LED products and theory breakthrough

06 Dec 2017

The project led by Professor Ron S.Y. Hui, Chair of Power Electronics at the Faculty of Engineering of the University of Hong Kong on sustainable lighting systems has led to both theoretical and practical breakthroughs. Novel LED systems with not only high energy efficiency and luminous efficacy, but also lifetime exceeding 10 years and over 80% product materials recyclable have been studied and developed. 

The project was funded by the Research Grants Council’s Theme-based Research Scheme.

Among the new sustainable lighting products developed by the team include the world’s first and only “sustainable LED street lighting system”, which meets all the three sustainability criteria of high energy efficiency, long product lifetime and recyclability. 

The research team stresses that the traditional Energy-Star concept which focuses on energy saving only is not necessarily environmentally-friendly or sustainable since lots of harmful electronic waste may be generated within a short product lifetime. 

The sustainable street lighting system has been pilot tested in Guangdong’s Heshan City with great success and will be implemented more extensively.

Professor Hui will hold a press conference tomorrow (December 7, Thursday) to introduce the new technologies, some already have patent applications filed. He will demonstrate the sustainable lighting system and an important latest innovation of a smart system for precise dimming and colour control of bicolour adjustable LED lamps.

Details of the media briefing are as follows:
Date: December 7, 2017 (December)
Time: 10:15am
Venue: Rm 515, Faculty Conference Room, Faculty of Engineering, 5/F., Haking Wong Building, HKU
