Lux, английский
- Unit of illumination. 1 lux = the amount of uniform light falling onto a surface of 1sq metre. measured in lumens per square metre.
- Unit of light illuminance used as a measure of low-light recording capacity in security cameras. cameras with a lux rating of 0.2 lux or less would be considered low-light cameras. it is not possible to get good color definition in low light levels, so in general low light cameras are always black and white. day/night cameras use electronics to switch from color during the daytime, to black/white during night or low light conditions. many low light cameras also use infrared, which is useful in zero light conditions. the lower the lux rating of a camera, the better it will see in low light.
- International system (sl) unit of illumination in which the meter is the unit of length. one lux equals one lumen per square meter.
- The international system unit (see si) of measurement of the intensity of light. it is equal to the illumination of a surface one meter away from a single candle.
- Unit of n equal to 1 lumen per square meter or approximately 0.1 candle power. glossary/52 m
- The metric unit (lumens per square metre) for the measure of luminous flux (also see
- A unit of measure of incident light. the video and european version of foot candles. conversion formula: fc x 10.8 = lux.
- The si unit of illuminance equal to the illumination on a surface, all points of which are at a distance of 1 meter from a uniform point source of 1 candela; 1 lux is equal to 1 lumen per square meter (1 lm/m2). lwc abbr. for lightweight concrete.
- Люкс (единица освещенности)
- Люкс; лк (единица измерения освещенности)

Lux, латинский
Lux (lux), английский
The si measurement of light intensity taken at the surface which the light source is illuminating. the measure of the total lumens falling upon a unit of area. 1 lumen per square meter. one foot-candle equals 10.76 lux.

- Light unit for measuring illumination. it is defined as the illumination of a surface when luminous flux of 1 lumen falls on an area of 1 m2. it is also known as lumen per square meter, or meter-candelas. 23 / 43 m

Illuminance, английский
- The amount of light, which falls onto a given surface area. measured in lux.
- The light density, or luminous flux per unit area, incident on a surface.
- The density of luminous power, also called “illumination.” one lumen of luminous flux, uniformly incident on 1 square foot of area, produces an illuminance of 1 footcandle; in si units, one lumen of luminous flux, uniformly incident on 1 square meter of area, produces an illuminance of 1 lux.
- Освещ
- Intensity of radiant energy (density of luminous flux) on a surface, in the visible light spectrum. illuminance is measured in lux.
- Intensity of visible light per unit area (density of luminous flux) on a surface. illuminance is measured in lumens per square meter (lm/m2) or lux. compare luminance.
- Intensity of radiant energy in the visible light spectrum. illuminance is measured in footcandles or lux.
Photometer, английский
- Instrument that measures luminous intensity, luminous flux, light distribution or color.
- An instrument which measures luminous intensity.
- Any instrument that measures photometric quantities such as luminance, luminous intensity, luminous flux, and illumination.
- Device used to measure illuminance. the sensor is filtered such that its response closely matches the spectral responsivity curve of the human eye. in nondestructive testing, photometers measure lux. compare radiometer.
- Device used to measure luminance or illuminance. illuminance photometers are often called lux meters. photometer integral sensors are filtered such that their responsivity closely matches the spectral responsivity curve of the human eye (in other words, the action spectrum of interest). compare radiometer.

Manual zero, английский
Control on a test instrument that allows the user to zero the instrument panel meter.
Luminous exitance, английский
Luminous flux per area, emitted or reflected from a certain location on a surface. measured in lumens per square meter (lm/m2). compare radiant exitance.
