Lumen, английский
- Unit of light measurement of light radiation. 1 lumen = amount of light emitted by a light source of 1 candela.
- In wood anatomy, the cell cavity.
- Люмен
- Unit of light flux.
- Unit of luminous flux defined as total flux in a space angle of one steradian and
- A unit of measurement of incident light. lumens, like lux, flux, candela, foot candles, foot lamberts, and watt/seconds, were created by scientists and engineers to confuse artists.
- 1. an si unit of light emitted per second 2. the inside width of a passage in the body or of an instrument such as an endoscope 3. a hole at the end of an instrument such as an endoscope
- Space inside the cisternae of the endoplasmic reticulum in eukaryotic cells
Lumen, латинский
(лат.) — свет. lumen naturale и lumen supranaturale — см. метафизика света.
Lumen (lm), английский
The unit of luminous flux. it is equal to the flux through a unit solid angle (steradian) from a uniform point source of one candela or to the flux on a unit surface of which all points are at a unit distance from a uniform point source of one candela.
Lumen (pt, mt), английский
A measure of the brightness of light. a unit of luminous flux equal to the light emitted in a unit solid angle by uniform point source of one candle.
Lumen , inis, n, латинский
Lumen maintenance curve, английский
Lumen method, английский
Lighting design procedure used for predetermining the relation between the number and types of lamps or luminaires, the room characteristics and the average illuminance on the work plane. it takes into account both direct and reflected flux. also called flux method.2,6
Lumen mundi, латинский
Светоч мира
Lumen naturale, латинский
(лат. – "естественный свет") — восходящее к античной метафизике света понятие, характеризующее конечность человеческого познания. по августину, полнота знания достигается только благодаря излучаемому богом сверхъестественному свету (lumen supranaturale), дополняющему естественный свет.
Lumen of the trachea, английский
Lumen [inis, n], латинский
Lumen [lm], английский
- A light intensity produced by the luminosity of 1 candela in one radian of a solid
- A light intensity produced by the luminosity of 1 candela in one radian of a solid angle.
- Люмен [лм]. световой поток, распространяемый источником с силой света в 1 канделу внутри единичного телесного угла.
Lumen, inis, n, латинский
Lumen/ft2, английский
A unit of incident light. it is the illumination on a surface one square foot in area on which a flux of one lumen is uniformly distributed, or the illumination at a surface all points of which are at a distance of one foot from a uniform source of one candela.
Lumenescent penetrant, английский
Lumenescent way, английский
Lumenescent-coloured penetrant, английский
Lumenescent-coloured way, английский
Lumens, английский
Unit of measure for total light output. the amount of light falling on a surface of one square foot.
Watt, английский
- Basic unit of power. the formula is voltage multiplied by the current, or v x amps.
- A unit of power that equals one joule per second, named after the scottish inventor and mechanical engineer, james watt
- A unit of electrical energy or power; one ampere x one volt = one watt.
- Ватт
- A unit of power (equivalent to one joule per second) used to express laser power.
- A unit of power; the power required to do work at the rate of 1 joule per second, which is equal to the power dissipated in an electric circuit in which a potential difference of 1 volt causes a current of 1 ampere to flow. watt-hour a unit of work equal to 3,600 joules; equivalent to the power of 1 watt operating for a period of 1 hour. watt-hour meter an electricity meter which measures and registers the active power in an electric circuit with respect to time.
- The unit of measure for electric power or rate of doing work. the rate of energy transfer equivalent to one ampere flowing under pressure of one volt.
- The rate of energy transfer equivalent to one ampere under an electrical pressure of one volt. one watt equals 1/746 horsepower, or one joule per second. it is the product of voltage and current (amperage).
- An si unit of power equal to one joule per second.
