The diagram demonstrates how an LED (light emitting diode) flashlight activates .LED flashlight, which is a compact device, consist of five main parts: batteries, protective cover, a slide switch, the circuit and the bright LED bulb.
About the structure of the flashlight. First, the cover protects the inside safe before impact or water. The slide switch, which is used to turn the light on or off with a simple touch, is considered the most essential part. Then inside it contains devices such as circuit, wires, batteries and light bulb. The batteries, power providing part, make sure flashlight’s continuous operation, especially in critical situations. The circuit is carefully designed to connect batteries to the LED bulb enable electricity flow stably. The LED light bulb, thanks to energy-saving feature, create powerfully light without running out of energy.
As for the principle of operation. The slide switch, when moved up, connects the broken circuit, closing the circuit and allowing electricity to flow and allow the bulb to shine. In contrast, when the slide switch moves down, the circuit disconnects, so the flow of current doesn’t flow and it makes the flashlight off. The flashlight run based on principle of closing and opening circuit, a simple mechanism yet very effective. Regarding the flashlight’s design not only user-friendly but also lightweight, additionally, it has a long battery, is very suitable when go camping or power outages.
