Do not need plug Power Supply, LED bulb emits bright light! 13th at Southeast University's innovation laboratory, The electrical engineering science and technology Department, Ni Linyi, a senior showed a fantastic feature of wireless power settings. Jiangsu Province, in the just-completed 2014 undergraduate electronic design contest, this convenient and efficient plant won the first prize. Winner was a famous "inventor" in College, he received four patents.
"The principle of wireless power transmission is very simple, it is the electromagnetic conversion. "Ni Linyi said transmitting coil convert the direct current magnetic field and emitted, the distance of half a meter outside of the receiving coil will" catch " and converted to electrical energy, transmitted to the LED light bulb, bulbs naturally lights. Of course, in the process of conversion, transport, power, inevitably there will be some losses. How to the minimize loss and improve the power conversion rates became the key points. "Because after a precise analysis of circuit design, the equipment of energy conversion rate reached 67%. " under the careful supervision of teacher Zhang Zhipeng and Cao Chengwei, Ni Linyi, Sha Yangyang and Li Youjian three students by trial and improvement, finally won the 2014 undergraduate electronic design contest of Jiangsu Province.
"Modern power equipment brings great convenience for our life, but as a spider web-like wires also are headaches. "Ni Linyi said, wireless power transmission could solve this problem, household appliances can get rid of" little tail ", electric toys for children would not have to replace the battery. People can be assured of is that the principle of wireless power transmission is using electromagnetic conversion, the human body hardly have response to magnetic fields , so the system will not affect human health.
