Lumen per Square Meter Steradian

lm/(m²·sr)

Definition

The Lumen per Square Meter Steradian is a unit of luminance that explicitly shows the relationship between luminous flux, area, and solid angle. It is dimensionally equivalent to candela per square meter and provides insight into the geometric aspects of light measurement.

History/Origin

This unit was developed to emphasize the relationship between luminous flux, surface area, and solid angle in luminance measurements. It provides a more detailed understanding of how light is distributed and measured in three-dimensional space.

Current Use

Used in advanced photometry and lighting calculations where the relationship between flux, area, and solid angle is important. Common in research applications and detailed lighting analysis where understanding the geometric aspects of light distribution is crucial.
