Luminous, английский
Светящий(ся)
Luminous -, английский
Светимость (в точке поверхности)
Luminous ., английский
Luminous absorption, английский
Luminous ceiling, английский
A ceiling area-lighting system comprising a continuous surface of transmitting material (of a diffusing or light-controlling character) with light sources mounted above it.
Luminous efficacy, английский
- The ratio of the total emitted luminous flux, in lumens, to the total electric power consumption in watts.
- Ratio of the total luminous flux of a light source to the total radiant flux or to the power input. sometimes called luminous efficiency.
Luminous efficacy; also called the luminous coefficient., английский
Luminous efficiency, английский
Luminous efficiency; light output, английский
Luminous energy, английский
- A measure of rate of flow of flux. it has units of lumen-seconds.
- The time integral of luminous flux; given by the product of the luminous flux and the time that the flux is maintained, if the luminous flux is of constant value; usually expressed in lumen-hours.
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.
Luminous flame, английский
Светящееся пламя
Luminous flux, английский
- The rate of flow of light.
- A measure of flow of visible light energy past any given point in space. it is
- The rate-of-flow of radiant energy emitted by a lamp.
- Radiant energy’s time rate of flow. measured in lumens.
- Luminous energy per unit time as measured in lumens. compare radiant flux.
Luminous intensity, английский
- The luminous flux per unit solid angle in a specific direction from a point source of light; in practice, an interior source may be considered a point source if the distance exceeds 5 to 10 times the maximum source dimension of the luminaire; in us customary units, expressed in candlepower; in si units, expressed in candelas. luminous-intensity distribution curve a polar plot representing the light intensity as a function of angle about a light source. luminous transmittance 609 luminous-intensity distribution curve luminous paint 1. phosphorescent paint, which, after activation, continues to emit light (even in darkness) for several hours. 2. fluorescent paint, which has a high light reflectivity because it reflects absorbed ultraviolet energy as visible light.
- Measure of a light source’s power output per unit solid angle emitted or reflected from a point, when weighted by the photopic spectral luminous efficiency response curve. luminous intensity is measured in candela. compare luminance.4 lux (lx): si unit of illuminance, equal to one lumen per square meter (1 lx = 1 lm·m–2). m
- Luminous flux per unit solid angle in the direction of interest. measured in candela. compare luminance; radiant intensity. lux (lx): si unit of illuminance, equal to one lumen per square meter (1 lx = 1 lm/m2).
- Measure of a light source’s power output per unit solid angle emitted or reflected from a point, when weighted by the photopic spectral luminous efficiency response curve. luminous intensity is measured in candela. compare luminance. lux (lx): si unit of illuminance, equal to one lumen per square meter (1lx=1lm·m–2). m
Luminous medium, английский
Luminous paint. phosphor mercury-vapor lamp a highpressure mercury-vapor lamp consisting of an arc tube enclosed by a phosphor-coated glass envelope; the phosphor generates colors not produced by the arc., английский
Luminous transmittance, английский
Of a lens, light diffuser, or the like: the ratio of the total transmitted light to the total incident light.
Luminous transmittance. coefficient of performance 1. in a heat pump, the dimensionless ratio of heat produced to the energy supplied. 2. in a refrigerating unit, the dimensionless ratio of the heat removed to the energy expended in removing it., английский
