The Hong Kong Polytechnic University successfully developed the most power-saving LED filament lamp on the market using new nano-processing technology. The luminous efficiency is 1.5 times that of a traditional LED lamp. The price and cost are half that of a traditional LED lamp. The annual electricity bill and carbon emission of the filament lamp are even more Less than half of the traditional gall bladder, is expected to be produced and launched in the market this year.

Polytechnic State Key Laboratory of Ultra-precision Machining Technology, and technology research and development, PolyU Department of Industrial and Systems Engineering graduate Zhao Chongzhi, developed the most economical on the market LED filament technology. "The new technology, due to my dissertation, was originally intended as a thesis topic, and I hoped to combine the advantages of all kinds of electric lamps to develop a new type of lamp, including the thesis time, which took a total of two and a half years to make. Very pleased to be able to apply for a patent. " He said that LED filament lamps use multiple low-power LED chips instead of single-chip high-power LED chips to reduce current consumption and improve the uniformity of light distribution. The material supporting the chips is also changed from ceramic to heat dissipation with low cost and high light intensity Of the aluminum, its luminous efficiency of 129 lumens / watt (lm / W), about 1.5 times and 2 times higher than the traditional LED lamps and boilers, ultraviolet light is one-tenth of the traditional boilers.
