The luminous flux incident on unit area of a surface; measured in lux or lumens
Illuminance is a measure of luminous flux per unit area Illuminance is typically expressed in lux (lumens per square meter) or foot-candles (lumens per square foot)
The total luminous flux received on a unit area of a given real or imaginary surface, expressed in such units as the foot-candle, lux, or phot
The quantity of light (foot candles lux) at a point on a surface Formula: Illuminance=Lumen/Square Foot
is the luminous flux density at a surface, i e the luminous flux incident per unit area The unit of illuminance is lux, that is, lumens per square metre Note: the term ‘illumination’ is now used only to describe the general process of lighting
The "density" of light (lumens/area) incident on a surface Illuminance is measured in foot-candles or lux
-The density of the luminous flux incident on a surface It is the quotient of the luminous flux multiplied by the area of the surface when the later is uniformly illuminated
Luminous flux incident per unit of area
the luminous flux incident on a unit area
{i} intensity of light, strength of light (Optics)
solar radiation in the visible region of the solar spectrum to which the human eye responds
The strength of light falling on a given area of a surface Measurable by an incident-light (illuminance) meter
the density of the luminous flux incident on a surface; it is the quotient of the luminous flux by the area of the surface when the latter is uniformly illuminated
The amount of light falling into a patch of unit surface area It is measured in lux
Density of the luminous flux incident upon a surface It is the quotient of the luminous flux by the area of the surface when the latter is uniformly illuminated
The density of luminous flux incident upon a surface Illuminance is measured in footcandles (lumens/square foot) or lux (lumens/square meter) One footcandle equals 10 76 lux
The density of luminous flux on a surface, is measured in footcandles (one lumen per square foot) or lux (one lumen per square meter)
The density of incident luminous flux on a surface; illuminance is the standard metric for lighting levels, and is measured in lux (lx) or footcandles (fc)
is the light on a surface expressed in lumens per the defined area 1 lumen per square foot equals 1 foot-candle
The measurement o light in lumens per square metre, the unit of which is the lux
Light arriving at a surface, expressed in lumens per unit area; 1 lumen per square foot equals 1 footcandle, while 1 lumen per square meter equals 1 Lux
The “density” of light (lumens/area) incident on a surface Illuminance is measured in foot-candles or lux
The density of LUMINOUS FLUX incident on a surface Illuminance is calculated as the amount of LUMENs per unit area Two common units used to measure illuminance are footcandles (lumens per square foot) and lux (lumens per squere meter) For conversion purposes, 1 footcandle is equal to 10 76 lux
The integrated visible light arriving at a surface, expressed in SI units of lumens per square meter, or lux (Compare to irradiance )
