Prof. Ron Hui Shu-yuen, Chair of Power Electronics, Department of Electrical and Electronic Engineering and his research team has invented a passive light-emitting diode (LED) driver that is suitable for outdoor street lighting and with a lifespan comparable to LED devices. With a lifespan of more than 15 years, the passive LED driver can operate with high-energy efficiency under extreme weather conditions, including subzero temperatures, thunder, lighting and wide temperature variations. More than 80 percent of the driver’s components can be recycled. The technology has been licensed to a tech company in Hong Kong. Following a successful initial trial run earlier this year in Heshan city, Guangdong, the company is now partnering with a listed firm to manufacture the new LED street lighting products on a mass scale for a larger trial run in the same city this summer, with plans for the new LED street lighting products to become available on the market in 2016!
