Sep 30, 2023
The unit of illuminance is the candela per square meter (cd/m²), commonly represented as "lux," and it is the international standard unit for illuminance. One lux is equal to one candela of luminous flux uniformly distributed over a square meter of surface. Illuminance is used to measure the brightness of light incident on a specific surface and is a measure of luminous intensity. In practical applications, illuminance is often used to describe the brightness output of lighting fixtures and the intensity of ambient light, making it important in fields such as indoor lighting, photography, and architectural design.
