Hongkong science and technology research and development of the most energy-efficient LED filament Technology

Reporter Tang Xiaoming reports: Hong Kong Polytech University, the use of new nano machining technology, the successful development of market power LED filament lamp, luminous efficiency for the traditional LED lamp 1.5 times, the price and the cost is half of the traditional LED lamps, filament lamps a year electricity and carbon emissions of more than half of the traditional CFLs, expected production and market this year.

State Key Laboratory of ultra precision machining technology, and technology research and development, science and technology, industrial and systems engineering graduates Zhao Chongzhi, developed the current market the most energy-efficient LED filament technology. The new technology is due to my graduation thesis, originally conceived the title of the thesis, I hope to combine the advantages of various types of lamps, developed a new type of lamp, including graduation papers, including a total of two and a half years to make. Very pleased to be able to apply for a patent for this product. "

Zhao Chongzhi said that the products of the total development cost of about 300 thousand yuan (HK $, the same below), 2015 "mini fund allocated one hundred thousand yuan, the balance by laboratory support, is currently working with four to five companies to discuss cooperation, this year is expected to launch production and market.

He said, LED filament lamp we use multiple small power LED chip to replace the single high power LED chip, reduce current consumption, light distribution, supporting chip material, also made of ceramic to better heat dissipation, low cost, strong luminosity of aluminum, the luminous efficiency of 129 LM / Watt (lm/W), ca. for the traditional LED lamp and light bulbs were 1.5 times and 2 times, the ultraviolet ray is the traditional CFLs 1/10.

Ultra precision machining technology of State Key Laboratory of deputy director Du Xue said, because the LED filament lamp without using the variable pressure parts directly by alternating current into low voltage DC power, to reduce parts and improve the luminous efficiency, lighting so the retail price and the costs were 45 yuan and 20 yuan, about half of the traditional LED lamp, a lamp filament years of electricity and carbon emissions, respectively, 33 yuan and 22kgCO2E, less than half of the traditional CFLs below.
