By shaking the light, you cause the magnet to pass through a coil of copper wire. This creates the electrical energy that is used to power the world's brightest T1. 75 LED diode. What does this all mean? It means that the NightStar Shake Flashlight will always work.
Consequently, how does a shaking flashlight work?
When we shake the flashlight, the magnet moves back and forth, resulting in a current that reverses direction back and forth. Therefore, we will connect two diodes across the wire coil, in “anti-parallel” configuration, Figure 3. Figure 3. The LED's are connected anti-parallel.
