Effective Intensity for an abrupt Flash of Constant Illuminance Solution

STEP 0: Pre-Calculation Summary

Formula Used

effective_intensity = (Instantaneous Intensity *Flash Duration)/Illumination Constant +Flash Duration
I_e = (I*t)/a+t
This formula uses 3 Variables

Variables Used

Instantaneous Intensity - Instantaneous Intensity of Light (Measured in Lux)
Flash Duration - Flash Duration for a steady burning light (Measured in Second)
Illumination Constant - Illumination Constant for steady burning light

STEP 1: Convert Input(s) to Base Unit

Instantaneous Intensity : 50 Lux --> 50 Lux No Conversion Required
Flash Duration: 10 Second --> 10 Second No Conversion Required
Illumination Constant : 0.2 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

I_e = (I*t)/a+t --> (50*10)/0.2+10

Evaluating ... ...

I_e = 2510

STEP 3: Convert Result to Output's Unit

2510 Lux --> No Conversion Required

FINAL ANSWER

2510 Lux <-- Effective Intensity

(Calculation completed in 00.015 seconds)

What is Allard's law for Illumination?

Allard's law for Illumination is a formula relating the illuminance produced on a normal surface at a given distance from a point source of light, the intensity of the light and the degree of transparency of the atmosphere (assumed uniform). I is the intensity of the incident light in the direction of measurement.
