Hong Kong Research of passive LED power, long service life and can save maintenance costs

The Hongkong area has more than one hundred and forty thousand traditional high pressure sodium lamp, but lower than the energy consumption and environmental protection. Developed by the University of Hong Kong, Hong Kong patented "LED" passive power projection lamp, high-pressure sodium lamp is a traditional province of nearly 70% energy, and estimating service life for 15 years, compared with the traditional LED lamp use period of 5 years. The technology for people to recognize the "passive" LED power technology cost, compared with the traditional LED lamp "active" power cost is higher, but the long-term for users to save maintenance costs, the material is also relatively easy to recycle.

It is reported, Federal Group Global, developed by University of Hong Kong Limited patented "LED" passive power, driven by street lamps can be overcome under high temperature operating predicament, can use at least 60 thousand hours per year; 4000 hours calculation, disguise can live up to 15 years.

Federal Group Global Limited CEO Wang Hanbang explained, "LED power" passive technology is not affected by the temperature of the electrolytic capacitor, and power supply can withstand strong electromagnetic radiation generated by lightning, so we can make the failure rate dropped significantly, thereby reducing maintenance costs.

However, Wang Hanbang acknowledged that the "passive" LED power supply cost about one thousand and two hundred yuan, far more "active" LED power supply costs about four hundred yuan, but he was quoted in the Jiangmen pilot program in Heshan City, to more than three hundred supported by "LED" driving lamp passive power nearly four years without any damage, can reflect the save The cost of maintenance.

According to reports, the new LED lights at the Geneva International Exhibition of inventions won the special award and special gold award, there are currently 13 lamps in Hongkong rocky and Sha Tin and other trial.
