Electrical Engineering of flashlight

Electrical Components in a Flashlight Power source Light source On/off switch

Power Source Power used in Mag-light we chose: –AA batteries Other options: –AAA batteries –C batteries –Wind up –Battery charged by solar power

Light Source Bulb in Mag-light –Krypton Incandescent light bulb Other options –L.E.D –Halogen Incandescent –Xenon Incandescent

On/Off Switch Mag-light –Twist switch Other options –Push button –Flip switch

Our Ideas How we can improve the electrical design –Use L.E.D bulb Durable (Long Lifespan, Hard To Break) Uses Low Amounts Of Energy Does Not Create Heat –Use a push button switch Faster On & Off Capabilities
