Formula

The formula to calculate Lux (lx) from Lumens (lm) is:

\[ E_v (\text{lx}) = \frac{\Phi_v (\text{lm})}{A (\text{m}^2)} \]

Where:

Lumen to Lux Definition

Lumen (lm) is a unit of luminous flux, representing the total amount of light emitted by a source. Lux (lx) is a unit of illuminance, representing the amount of light that hits a surface. The conversion from lumens to lux depends on the area over which the light is spread.

Example Calculation

Let's assume the following values:

Using the formula:

\[ E_v = \frac{1000}{10} \]

\[ E_v = 100 \text{ lx} \]

The Illuminance (lx) is 100 lx.
