Light flux Solution

STEP 0: Pre-Calculation Summary

Formula Used

Flux = Photoelectric Current/Photoelectric Sensitivity
Φ = I_pc/P_s
This formula uses 3 Variables

Variables Used

Flux - (Measured in Lumen) - Flux is the measure of the perceived power of light.
Photoelectric Current - (Measured in Ampere) - Photoelectric Current is the electric current through a photosensitive device.
Photoelectric Sensitivity - Photoelectric Sensitivity is defined as the smallest absolute amount of change that can be detected by a measurement.

STEP 1: Convert Input(s) to Base Unit

Photoelectric Current: 12 Ampere --> 12 Ampere No Conversion Required
Photoelectric Sensitivity: 3.1 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

What is luminous intensity of LED?

The quantity of partial LED flux was introduced in CIE publication 127-2007. Luminous intensity involves a flux and a solid angle and is the ratio of the two; hence its unit is the candela which is the lumens per steradian.

How to Calculate Light flux?

Light flux calculator uses Flux = Photoelectric Current/Photoelectric Sensitivity to calculate the Flux, The Light flux formula is defined as is energy per unit time that is radiated from a source over visible wavelengths. More specifically, it is energy radiated over wavelengths sensitive to the human eye, from about 330 nm to 780 nm. Thus, luminous flux is a weighted average of the Radiant Flux in the visible spectrum. Flux is denoted by Φ symbol.

How to calculate Light flux using this online calculator? To use this online calculator for Light flux, enter Photoelectric Current (I_pc) & Photoelectric Sensitivity (P_s) and hit the calculate button. Here is how the Light flux calculation can be explained with given input values -> 3.870968 = 12/3.1.

FAQ

What is Light flux?

The Light flux formula is defined as is energy per unit time that is radiated from a source over visible wavelengths. More specifically, it is energy radiated over wavelengths sensitive to the human eye, from about 330 nm to 780 nm. Thus, luminous flux is a weighted average of the Radiant Flux in the visible spectrum and is represented as Φ = I_pc/P_s or Flux = Photoelectric Current/Photoelectric Sensitivity. Photoelectric Current is the electric current through a photosensitive device & Photoelectric Sensitivity is defined as the smallest absolute amount of change that can be detected by a measurement.

How to calculate Light flux?

The Light flux formula is defined as is energy per unit time that is radiated from a source over visible wavelengths. More specifically, it is energy radiated over wavelengths sensitive to the human eye, from about 330 nm to 780 nm. Thus, luminous flux is a weighted average of the Radiant Flux in the visible spectrum is calculated using Flux = Photoelectric Current/Photoelectric Sensitivity. To calculate Light flux, you need Photoelectric Current (I_pc) & Photoelectric Sensitivity (P_s). With our tool, you need to enter the respective value for Photoelectric Current & Photoelectric Sensitivity and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
