Number of Lamps Required for Illumination Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Lamp = (Illumination Intensity*Area of Illumination)/(Luminous Flux*Utilization Factor*Maintenance Factor)
N_Lamp = (E_v*A)/(F*UF*MF)
This formula uses 6 Variables

Variables Used

Number of Lamp - Number of lamps refers to the quantity of individual light sources used in a lighting system. It represents the count of separate lamps employed to provide illumination in a given space.
Illumination Intensity - (Measured in Lux) - Illumination intensity refers to the level or strength of light in a given area. It quantifies the amount of light reaching a surface and is typically measured in units such as lux or foot-candles.
Area of Illumination - (Measured in Square Meter) - Area of illumination refers to the size or extent of the space covered by light from a source, determining the reach and coverage of light in that area.
Luminous Flux - (Measured in Lumen) - Luminous flux is a measure of the total amount of light emitted by a light source in all directions. It quantifies the overall brightness or output of the source.
Utilization Factor - Utilization factor refers to a percentage or factor that represents the efficiency or effectiveness of a lighting system in delivering and utilizing light to the intended area or task.
Maintenance Factor - Maintenance factor refers to a multiplier or percentage used to adjust the initial illumination levels of a lighting system to account for degradation and dirt accumulation over time.

STEP 1: Convert Input(s) to Base Unit

Illumination Intensity: 1.02 Lux --> 1.02 Lux No Conversion Required
Area of Illumination: 41 Square Meter --> 41 Square Meter No Conversion Required
Luminous Flux: 42 Lumen --> 42 Lumen No Conversion Required
Utilization Factor: 0.15 --> No Conversion Required
Maintenance Factor: 2 --> No Conversion Required

STEP 2: Evaluate Formula
