The Parts
Case-The housing, usually a tube, that holds the parts together
Switch-Component that controls the flow of electricity
Reflector-Plastic or metal piece that mounts around the lamp
Contacts-Thin metal springs or strips that complete the electrical circuit
Lamp-The light source, either a tungsten filament or a light emitting diode
Lens-Clear glass or plastic that protects and magnifies the lamp
Batteries-The source of power for the Lamp
How They Work Together
Pushing the switch to the “on” postion” allows the contacts to complete the circuit between the lamp and the batteries. Once electricity flows from the batteries, the filament in the lamp, or the light emitting diode, begins to glow.
Battery placement is critical, since the electricity must flow from the positive terminal of the battery, through the lamp, to the negative terminal in order for the lamp to energized.
Once the filament or LED starts to glow, it produces a visible light that reflects off the reflector and away from the lens.
The lens focuses, and in some cases, magnifies the light, producing a steady beam.
Pressing the switch to the “off” position interrupts the flow of electricity and extinguishes the flashlight beam.
