Technical Information

What is "Electromagnetic Induction" and how do shake flashlights use it?

Shake flashlights use the Faraday Principle of Electromagnetic Energy to create the electricity they need to charge themselves. The Faraday Principle describes how a magnetic field can produce electric current in a wire coil that it passes through. Whena shake flashlight is shaken, a magnet slides back and forth through a copper wire coil. The electricity produced as a result is then stored in a capacitor instead of a battery.

What is a "Capacitor" and why do shake flashlights use one?

A capacitor is a basic electronic component that stores electric charge. A capacitor is used in the shake flashlights instead of a battery due to the fact that power is always available by shaking, thereby requiring less electricity storage than normal flashlights. Theshake flashlight's capacitor holds enough charge for up to an hour of light without further shaking.

What is an "LED" and why do shake flashlight use one?

An LED, or "Light Emitting Diode" is an electronic component that emits light when an electric current is applied to it. LED's, long used for electronic indicator lights, have become very popular for other llighting applications over the past few years in everything from street lights to roadway hazard lights and vehicles. A big reason for their popularity is their efficiency and lifespan. An LED is many times more efficient than a halogen or fluorescent bulb, uses much less power, and lasts for up to 10 years - a perfect match for shake flashlights!
