Led goniophotometer: what it is and how it's used

Image
An instrument called a goniophotometer measures the amount of light reflected off an item at various angles. With the advent of LED-light sources, where the spatial distribution of light is not uniform, goniophotometers have become more popular in recent years. A Lambertian source is one whose illumination is uniform over its surface. Severe requirements make it crucial that the spatial dispersion of light be considered when designing vehicle lighting. Both the kind of light source and the goniophotometer have a role in determining the number of distribution curves for luminous intensity and the measurement planes it may select. Three different kinds of goniophotometers are differentiated according to the measurement planes A, B, or C. By CIE 121-1996, and IES 62384 tester , the goniophotometers that are a part of the LISUN series are classified as type A goniophotometers. They are the foundational items of the Optronic Line and are the focus of ongoing development. Uses A
