What is the Luminance of the sun?

The sun has a luminance of about 1.6×109 cd/m2 at noon. Luminance is invariant in geometric optics. This means that for an ideal optical system, the luminance at the output is the same as the input luminance.

How to Calculate luminance?

luminance calculator uses Luminance=Electric Current/(Area*Cosine) to calculate the Luminance, The luminance formula is defined as the ratio between the current and the product of the area and cosine at a surface. It is denoted as L. Luminance and is denoted by L symbol.

How to calculate luminance using this online calculator? To use this online calculator for luminance, enter Electric Current (i), Area (A) and Cosine (cosθ) and hit the calculate button. Here is how the luminance calculation can be explained with given input values -> 22.91831 = 20/(50*0.01745329251994).

FAQ

What is luminance?
The luminance formula is defined as the ratio between the current and the product of the area and cosine at a surface. It is denoted as L and is represented as L=i/(A*cosθ) or Luminance=Electric Current/(Area*Cosine). Electric Current is the time rate of flow of charge through a cross sectional area, The area is the amount of two-dimensional space taken up by an object and Cosine is simply an angle which is the ratio of two side-length in a right angle triangle.
How to calculate luminance?
The luminance formula is defined as the ratio between the current and the product of the area and cosine at a surface. It is denoted as L is calculated using Luminance=Electric Current/(Area*Cosine). To calculate luminance, you need Electric Current (i), Area (A) and Cosine (cosθ). With our tool, you need to enter the respective value for Electric Current, Area and Cosine and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
