FAQ

What is Illumination by Lambert Cosine Law?
Illumination by Lambert Cosine Law formula is defined as the ratio between the product of the current and cosine to the square of the length at a surface and is represented as E=It/(l*l)*cosθ or Illumination=Total current/(Length*Length)*Cosine. Total current is the total or modulated current of an AM modulator, Length is the measurement or extent of something from end to end and Cosine is simply an angle which is the ratio of two side-length in a right angle triangle.
How to calculate Illumination by Lambert Cosine Law?
