Lambert is a unit of luminance in photometry, named after the Swiss mathematician and physicist Johann Heinrich Lambert. It represents the brightness of a surface emitting or reflecting light in a specific direction. One lambert equals the brightness of a perfectly diffusing surface emitting or reflecting one lumen per square centimeter in all directions. This unit is instrumental in fields like photography, astronomy, and vision science, where precise light measurements are crucial. Understanding lambert helps in the accurate quantification and comparison of the luminous output of various surfaces, thereby enhancing the study of light and its effects.
Definition of LumenLumen is a unit of luminous flux in the International System of Units (SI). It quantifies the amount of light emitted by a source per unit of time. In essence, one lumen is the luminous flux emitted within a solid angle of one steradian by a point source with a uniform intensity of one candela. Lumen serves as a fundamental unit for measuring light output in various applications, including lighting design, photography, and engineering. By understanding lumens, individuals can better assess the effectiveness of light sources, ensuring optimal illumination and energy efficiency in different environments.
| Lambert (la) | Lumen/square Foot/steradian (lm/ft²/sr) |
|---|---|
| 0.01 la | 0.1 lm/ft²/sr |
| 0.1 la | 1 lm/ft²/sr |
| 0.2 la | 2 lm/ft²/sr |
| 0.3 la | 3 lm/ft²/sr |
| 0.4 la | 4 lm/ft²/sr |
| 0.5 la | 5 lm/ft²/sr |
| 0.6 la | 6 lm/ft²/sr |
| 0.7 la | 7 lm/ft²/sr |
| 0.8 la | 8 lm/ft²/sr |
| 0.9 la | 9 lm/ft²/sr |
1 la = 10 lm/ft²/sr
0.1 la = 1 lm/ft²/sr
Example 1:
Convert 5 la to lm/ft²/sr:
5 la = 5 × 10 lm/ft²/sr = 50 lm/ft²/sr
Example 2:
Convert 3.5 la to lm/ft²/sr:
3.5 la = 3.5 × 10 lm/ft²/sr = 35 lm/ft²/sr
