[LED magic function] can not be plugged into the shining light

Note: do not plug the power cord, LED light bulb will shine!

Yesterday, the Southeast University into a college innovation laboratory, Department of electronic engineering, electronic science and technology, senior students Ni Linyi demonstrated a set of wireless power transmission function of the magic. In the just concluded 2014 Jiangsu college students electronic design competition, this convenient and efficient equipment to get the first prize of good results. The winner was a celebrated "inventor", during the University, he obtained four patents.

"The principle of power wireless transmission is very simple, that is, electromagnetic conversion. Ni Linyi introduction, the transmitter coil will be converted into a direct current magnetic field and fired out, and half a meter away from the receiving coil will capture the magnetic field, and converted to electricity, transmitted to the LED bulb, bulb naturally lit.

Of course, in the process of conversion, transmission, the inevitable loss of electricity. How to minimize the loss and improve the conversion rate of electrical energy has become the key point of the design. "Because of the precise design of the circuit, the energy conversion rate of the device is as high as 67%. "Zhang Zhipeng, Cao Chengwei, in the careful guidance of the teacher, Ni Linyi, Sha Yangyang, Li Youjian three students through repeated tests, finally won the first prize in 2014 in Jiangsu Province Undergraduate Electronic Design contest.

Modern power equipment to bring great convenience to life, but as the spider like wire is also a headache. Ni Linyi introduction, electric power wireless transmission can solve this problem, household appliances can get rid of the small tail, children's electric toys do not have to change the battery.

One can rest assured that the use of wireless transmission of electricity is the principle of electromagnetic conversion, the human body has little response to the magnetic field, so the system does not affect human health.
