Design and Development of a Wireless Lamp Charging System

Abstract

Wireless is a technology of transmitting power through an air gap to electrical devices for
the purpose of energy replenishment. The recent progress in wireless charging techniques
and development of commercial products has provided a promising alternative way to
address the energy tailback of unadventurously portable-power devices. This work is an
innovative application of Faraday’s laws of electromagnetic induction. A charging station
sends energy through inductive coupling to an electrical device, which stores the energy in
the batteries. Because there is a small gap between the two coils, inductive charging is one
kind of short-distance wireless energy transfer. Induction coils are attached to transmitter
and the portable device, so that the device receives power from the electromagnetic field
created by the transmitting unit and stores the energy in the battery.
