< 7 Methods of Lighting Calculators

Number of Lamps Required for Illumination

Go Number of Lamp = (Illumination Intensity*Area of Illumination)/(Luminous Flux*Utilization Factor*Maintenance Factor)

Intensity of Light Transmitted

Go Intensity of Transmitted Light = Intensity of Light Entering the Material*exp(-Absorption Coefficient*Path Length)

Number of Floodlighting Units

Go Number of Floodlighting Units = (Area to be Lighted*Illumination Intensity)/(0.7*Lumen Flux)

Spectral Transmission Factor

Go Spectral Transmission Factor = Transmitted Spectral Emission/Spectral Irradiation

Spectral Reflection Factor

Go Spectral Reflection Factor = Reflected Spectral Emission/Spectral Irradiation

Spectral Luminous Efficacy

Go Spectral Luminous Efficacy = Maximum Sensitivity*Photopic Efficiency Value

Luminance for Lambertian Surfaces

Go Luminance = Illumination Intensity/pi

Spectral Transmission Factor Formula

Spectral Transmission Factor = Transmitted Spectral Emission/Spectral Irradiation
T_λ = J_λ'/G_λ

What is meant by luminous transmission factor?

Luminous transmission factor (LTF) expresses the overall effect of a filter on a standard eye viewing a standard light source. The standard source currently used is determined by the Commission Internationale de l'Eclairage (CIE) as standard illuminant D65, which replicates a daylight source.
