Reflection Factor Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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.
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.

STEP 1: Convert Input(s) to Base Unit

Reflected Luminous Flux: 5.1 Lumen --> 5.1 Lumen No Conversion Required
Incident Luminous Flux: 2.3 Lumen --> 2.3 Lumen No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

ρ = Φ_r/Φ_i --> 5.1/2.3

Evaluating ... ...

ρ = 2.21739130434783

STEP 3: Convert Result to Output's Unit

2.21739130434783 --> No Conversion Required

FINAL ANSWER

2.21739130434783 ≈ 2.217391 <-- Reflection Factor

How many lumens is a Lux?

The total output of visible light from a light source is measured in lumens. Typically, the more lumens a light fixture provides, the brighter it is. One lux is equal to one lumen per square meter.
