Incident Luminous Flux Solution

STEP 0: Pre-Calculation Summary

Formula Used

Incident Luminous Flux = Reflected Luminous Flux/Reflection Factor
Φ_i = Φ_r/ρ
This formula uses 3 Variables

Variables Used

Incident Luminous Flux - (Measured in Lumen) - Incident Luminous Flux refers to the total amount of visible light energy emitted or received by a surface per unit time.
Reflected Luminous Flux - (Measured in Lumen) - Reflected Luminous Flux is defined as is a measure of the power of reflected visible light produced by a light source or light fitting.
Reflection Factor - Reflection Factor is the ratio of the total amount of radiation, as of light, reflected by surface to total amount of radiation incident on surface.

STEP 1: Convert Input(s) to Base Unit

Reflected Luminous Flux: 5.1 Lumen --> 5.1 Lumen No Conversion Required
Reflection Factor: 2.55 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Φ_i = Φ_r/ρ --> 5.1/2.55

Evaluating ... ...

Φ_i = 2

STEP 3: Convert Result to Output's Unit

2 Lumen --> No Conversion Required

FINAL ANSWER

2 Lumen <-- Incident Luminous Flux
