Summary:
This paper reports our laboratory's latest wireless-driven LED lighting system, which adopted wireless electrical energy transmission technology. Wireless power transfer technology is the transmission of electrical energy from a power source to an electrical load without man-made conductors. Traditional LED lighting system sensitive to rigid environment such as humidity, corrosive and flammable. Combining the advantages of wireless electrical power transfer and LED semiconductor lighting technology, the wireless-driven LED lighting system has advantages of electrical shock protection, convenient, reliable, portable and environmentally sound. The wireless-driven LED lighting source will gain increasing attention in the civilian consumer electronics market, military area and special lighting areas. To achieve wireless electric power transfer in LED lighting system, the wireless-driven LED lighting system should contain LED lighting module, wireless electrical power transfer system, LED driving circuit and electrical energy storage system. The LED lighting module was driven by the electrical power, which was transferred from a contact free system. Wireless-driven LED lighting system has a good market prospects, this new technology will make these innovative LED lighting products more available, convenient and reliable. In this paper, we mainly research in wireless electrical energy transmission tech, LED integrated package tech, LED driver circuit tech.
