Lumen per square meter per steradian, often abbreviated as lm/m²/sr, is a unit of measurement for luminance. Luminance describes the amount of light that passes through, is emitted, or reflected from a particular area, and falls within a given solid angle. It essentially quantifies the brightness that is perceived from a surface in a specific direction. This unit is fundamental in the field of photometry, a branch of physics concerned with measuring visible light. Lumen per square meter per steradian is crucial for accurately assessing and ensuring proper lighting levels in various environments, whether in engineering, photography, or general lighting design.
Definition of ApostilbApostilb, abbreviated as asb, is a unit of luminance in the centimeter-gram-second (CGS) system of units. It is used to describe the brightness of a surface emitting or reflecting light. Specifically, one apostilb equals the luminance of a perfectly diffusing surface emitting one lumen per square meter of surface area. The concept of apostilb is significant in photometry, where it helps quantify the perceived intensity of light on or from a surface. This unit provides an understanding of how bright a light source appears to the human eye, aiding in designing lighting solutions and ensuring comfortable visual environments.
| Lumen/sq. Meter/steradian (lm/m²/sr) | Apostilb (asb) |
|---|---|
| 1 lm/m²/sr | 1 asb |
| 2 lm/m²/sr | 2 asb |
| 3 lm/m²/sr | 3 asb |
| 4 lm/m²/sr | 4 asb |
| 5 lm/m²/sr | 5 asb |
| 6 lm/m²/sr | 6 asb |
| 7 lm/m²/sr | 7 asb |
| 8 lm/m²/sr | 8 asb |
| 9 lm/m²/sr | 9 asb |
| 10 lm/m²/sr | 10 asb |
1 lm/m²/sr = 1 asb
Example 1:
convert 5 lm/m²/sr to asb:
5 lm/m²/sr = 5 × 1 asb = 5 asb
Example 2:
convert 3.5 lm/m²/sr to asb:
3.5 lm/m²/sr = 3.5 × 1 asb = 3.5 asb
