The Origins of Induction Lighting
.
It has been a long stretch for the induction lighting systems since the first system was developed in the last century. Starting with the application of microwaves to the dissemination of light, now there is a fully functional induction street lighting solution in the market. Light production through electrodes has been found by many scholars to be wasteful and a great threat to the environment.
When non-renewable sources of energy are used concerns are raised as to the sustainability of this power. This has led to inventions that aim to conserve as much power as possible during any endeavor. The induction light has achieved this while making it possible to use the minimum power for each application. After eliminating electrodes, it is also found that lamps without them can last for several years while requiring little maintenance. The quality of light is also high regardless of the age of the bulb.
I know that magnetic induction can send electricity wirelessly to devices through the use of magnetic fields, but how does it work? How does the simple presence of a magnetic field produce electricity? Also, if it can, then why can’t permanent magnets be used as a source of perpetual energy, and why can’t we use the earth’s magnetic field to power our devices?
Oh, and is some power lost simply in the creation of the magnetic field? In other words, if you’re trying to send a given amount of electricity wirelessly through magnetic induction, is some of that power lost as it is used to create and sustain the magnetic field?
