Foot-lambert is a unit of luminance widely used in lighting and display industries. It represents the brightness of a surface that emits or reflects light, with one foot-lambert equal to the brightness of a surface emitting or reflecting one lumen per square foot. This unit is particularly useful in evaluating the luminance of screens, projectors, and other light-emitting surfaces, ensuring they meet desired brightness levels for optimal visibility and performance. By understanding foot-lambert, professionals can effectively measure and adjust the brightness of various surfaces to achieve the desired lighting conditions.
Definition of Lumen/sq. Meter/steradianLumen per square meter per steradian, often abbreviated as lm/m²/sr, is a unit of luminous intensity. It describes the amount of light that is emitted in a specific direction over a given area, accounting for the spread of light through a solid angle. This unit is crucial in fields like photometry and lighting design, where understanding the directional intensity of light is essential. By measuring light in lm/m²/sr, professionals can accurately assess how light is distributed across a surface, aiding in the design and evaluation of lighting systems to ensure optimal illumination and energy efficiency.
| Foot-lambert (fL) | Lumen/sq. Meter/steradian (lm/m²/sr) |
|---|---|
| 1 fL | 3.426 lm/m²/sr |
| 5 fL | 17.13 lm/m²/sr |
| 10 fL | 34.26 lm/m²/sr |
| 15 fL | 51.39 lm/m²/sr |
| 20 fL | 68.52 lm/m²/sr |
| 25 fL | 85.65 lm/m²/sr |
| 30 fL | 102.78 lm/m²/sr |
| 35 fL | 119.91 lm/m²/sr |
| 40 fL | 137.04 lm/m²/sr |
| 50 fL | 171.3 lm/m²/sr |
1 fL = 3.426 lm/m²/sr
1 lm/m²/sr = 0.292 fL
Example 1:
convert 10 fL to lm/m²/sr:
10 fL = 10 × 3.426 lm/m²/sr = 34.26 lm/m²/sr
Example 2:
convert 5 fL to lm/m²/sr:
5 fL = 5 × 3.426 lm/m²/sr = 17.13 lm/m²/sr
