Illumination - Units for Illuminations
1 Answer
Illumination, also known as luminous flux density or illuminance, refers to the amount of light that falls on a surface per unit area. It is typically measured in units of "lux" (lx) in the International System of Units (SI). One lux is defined as one lumen per square meter (lm/m²). Here's a breakdown of the units for illuminance:
1 Lux (lx) = 1 lumen/meter² (lm/m²)
Lumen (lm) is the unit of luminous flux, which measures the total amount of visible light emitted by a source.
Meter² (m²) represents the area over which the luminous flux is distributed.
In summary, illuminance is measured in lux and is a measure of the amount of light that illuminates a specific area. For example, if you have a light source that emits 100 lumens of light and that light falls on an area of 1 square meter, the illuminance at that point would be 100 lux.
1 Lux (lx) = 1 lumen/meter² (lm/m²)
Lumen (lm) is the unit of luminous flux, which measures the total amount of visible light emitted by a source.
Meter² (m²) represents the area over which the luminous flux is distributed.
In summary, illuminance is measured in lux and is a measure of the amount of light that illuminates a specific area. For example, if you have a light source that emits 100 lumens of light and that light falls on an area of 1 square meter, the illuminance at that point would be 100 lux.
