Lightning rod
| Глоссарий по архитектуре и конструкциям |
A rod-like electrical conductor attached to the highest exterior point of a building; provides a direct electrical path to the ground if lightning strikes the building, furnishing protection against lightning-induced damage; invented in 1752 by benjamin franklin, who established that lightning is an electrical phenomenon.

Молниеотвод, русский
- , устройство для защиты зданий, промышленных, транспортных, сельскохозяйственных и других сооружений от разрушительных последствий прямого попадания молнии. состоит из металлического стержня или троса, возвышающегося над защищаемым объектом, и из надежного заземления. часто молниеотвод ошибочно называют громоотводом.
- Устройство для защиты зданий и сооружений от прямых ударов молнии, состоящее из молниеприёмника, заземлителя и токоотводящих спусков, соединяющих молниеприёмник с землёй

Lightness, английский
- The attribute of visual perception in accordance with which an area appears to emit or reflect more or less light. also refers to the perception by which white objects are distinguished from gray objects, and light from dark colored objects.
- The whiteness of a painted surface as measured by the amount of light reflected from it.
- Осветленность; осветление
- The quality of a color that makes it appear brighter (closer to white) or darker (closer to black).
Lightning, английский
- All forms of visible electrical discharges moving through the atmosphere, usually eminating from tall cumulus and cumulonimbus clouds during thunderstorms. lightning is often categorized for the manner in which it is visible to the observer
- Молния
- Лайтнинг
- A discharge of atmospheric electricity, accompanied by a vivid flash of light, commonly from one cloud to another, sometimes from a cloud to earth or sea. standing out as they do above the vast flat expanse of ocean water, marine vessels, especially those with masts, can be prime targets for lightning seeking the most attractive path to ground. the most at risk are people on small boats, which are frequently made of wood or fiberglass that are poor conductors of electricity compared to the human body! hence the need for lightning conductors.

Lightning conductor, английский
A device designed to protect buildings or ships from the destructive effects of lightning. on watercraft, a metal plate (the “lightning protector”) is mounted at the main truck, or high on the superstructure of a vessel that does not have a mast. electrical conductors attached to the device run downward to a grounding conductor in contact with the water. on wooden ships the ground is usually the copper-bottoming, but for an iron or steel vessel it is the hull itself. for small vessels the grounding conductor may be retractable, part of the hull, or attached to a centerboard.
Lightning discharge, английский
A transfer of electrical charge along a narrow channel (the lightning channel), the result of a buildup of electrical pressure (voltage) between two distant points to levels to levels greater than the channel can resist. when the resistance breaks down, charge jumps across the space in a lightning dischar
Lightning explosion, английский
Lightning flash, английский
The complete visible flash of lightning accompanying a lightning discharge during one or a series of lightning strokes. a flash comprised of a number of strokes in rapid succession is also termed a composite flash.

Lightning network, английский
The lightning network is a decentralized network using smart contract functionality on the blockchain to enable instant payments across a network of participants. the lightning network will allow bitcoin transactions to happen instantly, without worrying about block confirmation times. it will allow millions of transactions in a few seconds, at low costs, even between different blockchains, as long as both chains use the same cryptographic hash function. the lightning network will allow two participants on the network to create a ledger entry, conduct a number of transactions between themselves and after the process has finished, record the state of the transactions on the blockchain. as for now, the bitcoin network is capable of processing up to 7 transactions per second. the visa payment network, for instance, is believed to complete 45,000 transactions per second during a regular holiday period. this protocol tries to solve the bitcoin scalability problem
