O knihe

High Quality Content by WIKIPEDIA articles! A flashlight (called a torch outside North America) is a portable electric spotlight that emits light from a small incandescent lightbulb or from one or more light-emitting diodes (LEDs). Typical flashlight designs usually consist of the light source located in a housing containing a parabolic reflector or specially shaped lens to shape the flashlight beam, a transparent window to protect the light source from damage and debris, a power source (typically electric batteries), and an electric power switch.While most flashlights are intended to be hand-held, there are also helmet-mounted flashlights designed for miners and campers and battery-powered lights for bicycles. Some flashlights are powered by hand-cranked dynamos or electromagnetic induction or are recharged by solar power.The name flashlight is used mainly in the United States and Canada. In other English-speaking countries, the more common term is torch or electric torch.
