Formula Used in “Lighting Calculator”
The standard formula used in our Lighting Calculator for calculating the required illuminance level in a given space is:
E = (P × UF × MF) / A
Where:
- E = Illuminance (in Lux)
- P = Total luminous output of the light source (in Lumens)
- UF = Uniformity factor (depending on the layout and application of the lighting)
- MF = Maintenance factor (accounting for dirt and depreciation in lamp output over time)
- A = Area of the space being illuminated (in square meters)
Step-by-Step Breakdown of the Formula
- Determine Total Luminous Output (P): Assess the luminous output provided by the lighting fixtures. This value is typically available on the product specifications and is measured in Lumens.
- Calculate Uniformity Factor (UF): Identify the uniformity factor which varies based on the light distribution, fixture arrangement, and space type. Values typically range from 0.7 to 1.0.
- Evaluate Maintenance Factor (MF): Choose an appropriate maintenance factor considering dirt accumulation and lamp depreciation. For most applications, this is often around 0.8.
- Measure the Area (A): Calculate the area of the space needing illumination. This value should be in square meters. Adjust based on the shape of the area (length × width for rectangular spaces).
- Perform the Calculation: Insert the values obtained into the formula to calculate the required illuminance level (E) in Lux.
Example Calculation
Let’s consider a simple example where we want to calculate the illuminance required for a small office space.
| Parameter | Value |
|---|---|
| Total Luminous Output (P) | 5000 Lumens |
| Uniformity Factor (UF) | 0.8 |
| Maintenance Factor (MF) | 0.8 |
| Area (A) | 30 square meters |
Calculating the Illuminance Level
Using the values above in our formula:
E = (5000 Lumens × 0.8 × 0.8) / 30
Calculating this will provide:
E = (3200 Lumens) / 30 ≈ 106.67 Lux
This illuminance level is suitable for a small office, ensuring optimal visibility for tasks.
