A '''torch light''', also known as a '''flashlight''' ({{lang-en|torch in British English and flashlight in American English}}), is a handheld portable light source that uses electricity. It is powered by batteries and equipped with an electric bulb or light-emitting diode ([[LED]]). Torch lights are widely used for illumination in various settings, such as homes, outdoor activities, emergencies, and industrial environments.<ref>{{cite web |title=Torch Light |url=https://www.britannica.com/technology/flashlight |access-date=December 15, 2024}}</ref><br />
<br />
== History ==<br />
The torch light was first patented in 1899 by [[David Misell]], an inventor working for the [[American Electrical Novelty and Manufacturing Company]]. Early models used incandescent bulbs and dry cell batteries, which provided limited light and required frequent recharging.<ref>{{cite web |title=History of Flashlights |url=https://www.nationalgeographic.com/science/article/flashlights-history |access-date=December 15, 2024}}</ref><br />
<br />
=== Evolution ===<br />
* Early torch lights used tungsten filament bulbs, which were later replaced by [[halogen lamps]] for better brightness.<br />
* The advent of LEDs revolutionized torch lights by offering higher energy efficiency, durability, and brighter light.<ref>{{cite web |title=LED Technology in Torch Lights |url=https://www.energy.gov/led-technology |access-date=December 15, 2024}}</ref><br />
* Modern torch lights often include features like adjustable focus, rechargeable batteries, and waterproof designs.<br />
<br />
== Components ==<br />
Torch lights generally consist of the following components:<br />
* '''Light Source''': Originally incandescent bulbs, now predominantly LEDs.<br />
* '''Reflector''': A curved surface that focuses the light beam.<br />
* '''Lens''': Protects the light source and directs the beam.<br />
* '''Body''': Made of plastic, aluminum, or steel, housing the components.<br />
* '''Power Source''': Batteries (alkaline, lithium, or rechargeable types like NiMH or Li-ion).<ref>{{cite web |title=Components of a Torch Light |url=https://www.engineeringtoolbox.com/torch-design |access-date=December 15, 2024}}</ref><br />
<br />
== Types ==<br />
Torch lights are available in various designs for different uses:<br />
* '''Handheld Flashlights''': Standard portable torches for general use.<br />
* '''Headlamps''': Hands-free torches worn on the head, commonly used in outdoor activities.<br />
* '''Tactical Flashlights''': Designed for military and law enforcement, featuring high-intensity beams and robust construction.<br />
* '''Emergency Flashlights''': Equipped with features like sirens, flashing lights, and solar or crank charging.<ref>{{cite web |title=Types of Torch Lights |url=https://www.outdoorgearlab.com/torch-types |access-date=December 15, 2024}}</ref><br />
<br />
== Applications ==<br />
Torch lights serve a variety of purposes, including:<br />
* Emergency lighting during power outages.<br />
* Outdoor activities like camping, hiking, and hunting.<br />
* Industrial and construction work.<br />
* Military and law enforcement operations.<br />
* Medical and rescue missions.<ref>{{cite web |title=Applications of Torch Lights |url=https://www.britannica.com/topic/flashlight |access-date=December 15, 2024}}</ref><br />
<br />
== Modern Innovations ==<br />
Torch lights have incorporated advanced technologies such as:<br />
* '''Rechargeable Batteries''': Using USB or wireless charging.<br />
* '''Smart Features''': Integration with mobile apps for brightness control and battery monitoring.<br />
* '''Eco-Friendly Designs''': Solar-powered and crank-operated models.<br />
* '''High-Intensity Discharge (HID) Lights''': For ultra-bright illumination.<ref>{{cite web |title=Innovations in Torch Lights |url=https://www.scientificamerican.com/torch-light-technologies |access-date=December 15, 2024}}</ref><br />
