Luminous Intensity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Luminous Intensity = Lumen/Solid Angle
I_v = Lm/ω
This formula uses 3 Variables

Variables Used

Luminous Intensity - (Measured in Candela) - Luminous intensity is a measure of the amount of light emitted by a light source in a specific direction. It quantifies the brightness or concentration of light in that direction.
Lumen - (Measured in Lumen) - Lumen is a unit of measurement that quantifies the total amount of visible light emitted by a light source. It represents the brightness or light output of the source, irrespective of direction.
Solid Angle - (Measured in Steradian) - Solid angle is a measure of the extent of a cone-shaped region in three-dimensional space, originating from a point and defined by its vertex angle. It quantifies the spatial coverage.

STEP 1: Convert Input(s) to Base Unit

Lumen: 41.85 Candela Steradian --> 41.85 Lumen (Check conversion here)
Solid Angle: 27 Steradian --> 27 Steradian No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

I_v = Lm/ω --> 41.85/27

Evaluating ... ...

I_v = 1.55

STEP 3: Convert Result to Output's Unit

1.55 Candela --> No Conversion Required

FINAL ANSWER

1.55 Candela <-- Luminous Intensity

What Is Polar Curve Of A Lamp?

A polar curve is a convenient way of showing how the candle power of a lamp varies in different directions. Polar curves are used to determine the M.H.C.P.,M.S.C.P. and the actual illumination of a surface by employing the candle power in the particular direction.

How to Calculate Luminous Intensity?

Luminous Intensity calculator uses Luminous Intensity = Lumen/Solid Angle to calculate the Luminous Intensity, Luminous intensity often referred to as candlepower, is a fundamental photometric quantity that describes the amount of visible light emitted by a light source in a specific direction per unit solid angle. It takes into account both the power of the light source and the human eye's sensitivity to different wavelengths of light. Luminous Intensity is denoted by I_v symbol.

How to calculate Luminous Intensity using this online calculator? To use this online calculator for Luminous Intensity, enter Lumen (Lm) & Solid Angle (ω) and hit the calculate button. Here is how the Luminous Intensity calculation can be explained with given input values -> 1.55 = 41.85/27.

FAQ

What is Luminous Intensity?

Luminous intensity often referred to as candlepower, is a fundamental photometric quantity that describes the amount of visible light emitted by a light source in a specific direction per unit solid angle. It takes into account both the power of the light source and the human eye's sensitivity to different wavelengths of light and is represented as I_v = Lm/ω or Luminous Intensity = Lumen/Solid Angle. Lumen is a unit of measurement that quantifies the total amount of visible light emitted by a light source. It represents the brightness or light output of the source, irrespective of direction & Solid angle is a measure of the extent of a cone-shaped region in three-dimensional space, originating from a point and defined by its vertex angle. It quantifies the spatial coverage.
