Light flux Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

Flux Light - (Measured in Lumen) - Flux Light 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: 5.2 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Φ = I_pc/P_s --> 12/5.2

Evaluating ... ...

Φ = 2.30769230769231

Luminous Intensity in Direction at Angle

Go Luminous Intensity at Angle = Luminance Normal to Surface*Surface Area*cos(Angle to Normal)

Transmission Factor

Go Transmission Factor = Luminous Flux Transmitted by Object/Luminous Flux Incident upon Object

Luminous Intensity in Direction Normal to Surface

Go Luminous Intensity Normal to Surface = Surface Area*Luminance Normal to Surface

Reflected Luminous Flux

Go Reflected Luminous Flux = Incident Luminous Flux*Reflection Factor

Incident Luminous Flux

Go Incident Luminous Flux = Reflected Luminous Flux/Reflection Factor

Area Projected at solid angle

Go Area Projected at Solid Angle = Magnetic Flux/Luminous Intensity

Intensity on Solid Angle

Go Luminous Intensity = Magnetic Flux/Area Projected at Solid Angle

Flux at Solid Angle

Go Magnetic Flux = Luminous Intensity*Area Projected at Solid Angle

Area of Bulb

Go Area of Bulb = Area of Capillary Tube*Length of Capillary Tube

Light flux

Go Flux Light = Photoelectric Current/Photoelectric Sensitivity

Illuminance

Go Illumination = Magnetic Flux/Surface Area

Area affected by Light Incident

Go Surface Area = Power Light/Irradiation

Light flux Formula

Flux Light = Photoelectric Current/Photoelectric Sensitivity
Φ = I_pc/P_s

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 Light = Photoelectric Current/Photoelectric Sensitivity to calculate the Flux Light, 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 Light 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 -> 2.307692 = 12/5.2.

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 Light = 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.
