Reduction Factor Solution

STEP 0: Pre-Calculation Summary

Formula Used

Reduction Factor = Mean Spherical Candle Power/Mean Horizontal Candle Power
RF = M.S.C.P./M.H.C.P.
This formula uses 3 Variables

Variables Used

Reduction Factor - Reduction factor refers to a multiplier or percentage used to adjust a measured value or calculation to account for specific factors or conditions that may affect the result.
Mean Spherical Candle Power - (Measured in Candela) - Mean Spherical Candle Power is a measure that represents the average intensity of light emitted by a source in all directions within a sphere. It quantifies the overall light output.
Mean Horizontal Candle Power - (Measured in Candela) - Mean Horizontal Candle Power is a measure that represents the average intensity of light emitted by a source along the horizontal plane.

STEP 1: Convert Input(s) to Base Unit

Mean Spherical Candle Power: 3.34 Candela --> 3.34 Candela No Conversion Required
Mean Horizontal Candle Power: 2.55 Candela --> 2.55 Candela No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

RF = M.S.C.P./M.H.C.P. --> 3.34/2.55

Evaluating ... ...

RF = 1.30980392156863

STEP 3: Convert Result to Output's Unit

1.30980392156863 --> No Conversion Required

< 15 Illumination Parameters Calculators

Number of Lamps Required for Illumination

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

Index of Refraction

Go Refractive Index of Medium 1 = (Refractive Index of Medium 2*sin(Refracted Angle))/sin(Incident Angle)

Luminance

Go Luminance = Luminous Intensity/(Area of Illumination*cos(Illumination Angle))

Luminous Flux

Go Luminous Flux = (Area of Illumination*Luminous Intensity)/(Length of Illumination^2)

Reduction Factor

Go Reduction Factor = Mean Spherical Candle Power/Mean Horizontal Candle Power

Mean Horizontal Candle Power

Go Mean Horizontal Candle Power = Sum of Candle Power/Number of Lamp

Solid Angle

Go Solid Angle = Area of Illumination/(Radius of Illumination^2)

Maintenance Factor

Go Maintenance Factor = Final Illumination/Initial Illumination

Illumination

Go Illumination Intensity = Luminous Flux/Area of Illumination

Mean Hemi-Spherical Candle Power

Go Mean Hemi Spherical Candle Power = Luminous Flux/(2*pi)

Mean Spherical Candle Power

Go Mean Spherical Candle Power = Luminous Flux/(4*pi)

Lamp Efficiency

Go Lamp Efficiency = Luminous Flux/Input Power

Candle Power

Go Candle Power = Luminous Flux/Solid Angle

Lumens

Go Lumen = Candle Power*Solid Angle

Depreciation Factor

Go Depreciation Factor = 1/Maintenance Factor

Reduction Factor Formula

Reduction Factor = Mean Spherical Candle Power/Mean Horizontal Candle Power
RF = M.S.C.P./M.H.C.P.

What do you mean by brightness and its unit?

The flux emitted per unit area of the source in a direction at right angles to the surface is known as brightness. Its unit is candles/m² or candles/cm² or candles/ft
