Title of patent: Electric saving device for fluorescent lamps
The Inventor: Mr. Nguyen Phan Kien,  Mr. Mac Van Hai, Mr. Vu Van Sang;
Address: Hanoi University of Science and Technology
Description of technology and equipment:

From the principle of reducing the excess energy in the bulb at the same time take advantage of natural energy while maintaining lighting standards of lighting the lamp, so the most important problem is to manufacture the microcontroller. To ensure energy savings, depend on the main controller completely. Identify the key idea, after finishing the motherboard in PC, the groups won a lot of effort to research and test many times for perfecting of the microcontroller. Finally, after many trials, the results were successful. From integrate circuit to the finished product.

            Electric saving products for those fluorescent lamps are installed outside so it does not impact on the nature of the bulb. Test results at the Technical Center 1 – Directorate of Metrology showed that the lighting equipment if passing the electric saving equipment can save up to 45 % which can still maintain the life of the bulb. Especially, according to calculations, the content of carbon dioxide emissions is 0,43 kg for every Kw hours of electricity, if only using the electric saving equipment for 50 bulbs so can also reduce carbon dioxide emissions by 0.7 tons per year .

In addition, the product allows to keep the room light constantly so the pupil of these people that have been working in this environment is not continuously changing, avoid eye fatigue and reduce short-sighted hazard. With special effects, this patent was awarded the first prize in Green Ideas contest in 2010.

Currently, the equipment has been used at Polytechnic University and a number of workshops aim to save the hundreds of millions of VND for spending electric energy per year. For to be more widely applied to households, the group is studying continuously for finishing aim to improve the capable of invention application widely and can reduce annual electricity shortage fears, bring useful results for society.
