Candela per Square Inch

cd/in²

Definition

The Candela per Square Inch is an imperial unit of luminance, representing the luminous intensity per unit area using the square inch as the area unit. It is used for measuring very bright light sources and small-area displays.

History/Origin

This unit was developed for applications requiring precise measurement of small, bright light sources where square inches provide a more appropriate area reference. It is particularly useful in electronics and display technology where component sizes are measured in inches.

Current Use

Commonly used in electronics manufacturing, small display technology, and precision lighting applications. Essential for measuring LED arrays, small screens, and compact light sources where square inch measurements are standard.

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.
