Formula Used in “Lumen Calculator (Lumen to Lux to Candela)”
The Lumen Calculator converts between lumens, lux, and candela using the following formulas:
If you want to convert lumens to lux, the formula is:
Lux (lx) = (frac{Lumens (lm)}{Area (m^2)})
To convert lux to candela, you would use:
Candela (cd) = (frac{Lux (lx) times Area (m^2)}{Solid Angle (sr)})
Step-by-Step Breakdown of the Formula
Understanding the variables used in the formulas will help you effectively use the Lumen Calculator. Below is a breakdown of each variable:
- Lumens (lm): The total amount of visible light emitted by a source.
- Area (m²): The surface area over which the light is distributed, measured in square meters.
- Lux (lx): A unit that measures illuminance, equal to one lumen per square meter.
- Candela (cd): A unit of measurement for luminous intensity in a given direction.
- Solid Angle (sr): A measure of two-dimensional angle in three-dimensional space, measured in steradians.
Example Calculation
To further clarify the conversion process, let’s consider a real-world example:
Assume we have a light source emitting 1000 lumens onto a surface area of 20 m². We want to calculate the illuminance in lux and the luminous intensity in candela if the solid angle is 1 steradian.
Calculation Steps
1. **Calculate Lux**:
Use the formula: Lux (lx) = (frac{Lumens (lm)}{Area (m²)})
Substituting values:
Lux = (frac{1000 text{ lm}}{20 text{ m}²} = 50 text{ lx})
2. **Calculate Candela**:
Use the formula: Candela (cd) = (frac{Lux (lx) times Area (m²)}{Solid Angle (sr)})
Substituting values:
Candela = (frac{50 text{ lx} times 20 text{ m}²}{1 text{ sr}} = 1000 text{ cd})
Summary of Inputs and Outputs
| Input Variable | Value |
|---|---|
| Lumens | 1000 lm |
| Area | 20 m² |
| Solid Angle | 1 sr |
| Output Variable | Value |
| Lux | 50 lx |
| Candela | 1000 cd |

- Review Results: Note the lux and candela values, which represent illuminance and luminous intensity, respectively.
Understanding the Input Fields
For accurate calculations, it’s vital to understand the input fields:
- Lumen: This is the total amount of visible light emitted by a source. For example, a standard 60-watt bulb emits approximately 800 lumens. Accurate lumen input helps ensure your lighting setup is sufficient for your space.
- Area Size (Square Meters): This field requires the size of the area you intend to light. For instance, if you have a room measuring 10 square meters, you would input ’10’. The area size directly affects the calculation of lux.
How to Interpret the Results
Once you hit the calculate button, the tool will output two main values: lux and candela.
- Lux: This value indicates illuminance, or how much light is distributed over a certain area. A typical office requires about 300-500 lux for working tasks. Make sure your area meets this requirement based on your needs.
- Candela: This represents luminous intensity, defined by how much light is emitted in a particular direction. Understanding candela helps in positioning your lights effectively.
Common Mistakes and How to Avoid Them
To ensure accurate results, avoid these common mistakes:
- Incorrect Lumen Input: Double-check the lumen value before calculation; using manufacturer specifications will yield the best results.
- Not Accounting for Area Size: An area size that is too small or too large will skew lux results. Always measure your area beforehand.
- Overlooking Directionality: Remember that candela is direction-dependent; if your light source has a lens, consider its angle when interpreting candela output.
