LED light bulbs can not be converted into electrical energy by the magnetic field of the power line

Don't plug in the power line, LED light bulbs will shine! Yesterday (13) day, in the Innovation Laboratory of Southeast University Cheng Xian college, Ni Linyi, a senior student of Electronic Science and technology in the Department of electronic engineering, showed a set of magical functions of radio transmission. In the 2014 Jiangsu university student electronic design competition, this convenient and efficient equipment won the first prize. The winner was a famous "inventor". During the University, he got four patents.

"The principle of radio transmission of electrical energy is very simple, that is, electromagnetic conversion." Ni Linyi introduced a coil that converts DC into a magnetic field and launches out, while a receiving coil outside half a meter will "capture" the magnetic field and convert it into electrical energy, which is transmitted to the LED bulb, and the bulb will naturally shine. Of course, in the process of conversion and transmission, electrical energy will inevitably have some loss. How to minimize the loss and improve the conversion rate of electric energy has become a key point in the design. "Because of the precise analysis of the circuit design, the energy conversion rate of this set of equipment is up to 67%." Under the careful guidance of Zhang Zhipeng and Cao Chengwei, the three students of Ni Linyi, Sha Yangyang and Li Youjian were improved through trial and error, and finally won the first prize in the 2014 Jiangsu college students' electronic design competition.

"Modern power equipment brings a great deal of convenience to life, but a spider - like wire is also a headache." Ni Linyi introduced that power wireless transmission can solve this problem, home appliances can get rid of the "small tail", and children's electric toys do not have to change batteries. People can also be assured that the wireless transmission of electrical energy is the principle of electromagnetic conversion, the human body has little response to the magnetic field, so the system does not affect the health of the human body.
