![]() ![]() The batteries rest atop a small spring that is connected to a contact strip. The batteries are connected in such a way that electricity (flow of electrons) runs between the positive and negative electrodes of the battery. When the switch of a flashlight is pushed into the ON position, it makes contact between two contact strips, which begin a flow of electricity, powered from the battery. How do all these flashlight parts work together? Whether you’re outdoors for a nighttime adventure or find yourself in the dark from a power outage after a storm, the convenience of portable light is as close as a simple button on your flashlight. LED's om flashlights are widely considered "unbreakable" and not replaced – a lifetime lamp.Ħ - Lens The lens is the clear, plastic part you see on the front of the flashlight that protects the lamp, since the lamp is made if glass and can easily be broken.ħ - Batteries When activated, the batteries are the power source for your flashlight. An LED contains a very small semiconductor (diode) that is encapsulated in epoxy and this part emits light when electricity flows through it. Tungsten is a natural element and the tungsten filament is a very thin wire. Tungsten lamps must be replaces when the tungsten filament breaks. The tungsten filament or LED glows when electricity flows through it, thus producing visible light. In most flashlights, the lamp is either a tungsten filament (incandescent bulb) or a light emitting diode (solid state bulb), also known as an LED. The flow of electricity is broken when the switch is pushed into the OFF position, thus turning off the light.Ĥ - Reflector A plastic part, coated with a shiny aluminum layer that rests around the lamp (light bulb) and redirects the light rays from the lamp to allow a steady light beam, which is the light you see emitting from the flashlight.ĥ - Lamp The light source in a flashlight. These parts conduct electricity and "hook everything up," completing the circuit.ģ - Switch The flow of the electricity is activated when you push the switch into the ON position, giving you light. Energizer ® Performance Metal Tactical Lightsġ - Case The tube that houses the parts of the flashlight, including the batteries and lamp (light bulb).Ģ - Contacts A very thin spring or strip of metal (usually copper or brass) that is located throughout the flashlight, making the electrical connection between the various parts – the batteries, the lamp, and the switch.Energizer ® Vision HD Performance Metal.It provides an easy way to handle your favorite videos and lets you enjoy them on a bigger screen with limited settings.
