When measuring the luminous intensity of a light source in accordance with the LM-79 standard, a goniophotometer of type C is the instrument of choice. Candelas are often used as a common unit of measurement for luminous intensity, which is defined as the quantity of light that is emitted in a certain direction (cd). The LM-79 standard offers a complete set of standards and processes for assessing the photometric and electrical properties of solid-state lighting (SSL) devices. These characteristics include lumen output, color rendering index, and power consumption. The use of a Type C goniophotometer, which is a highly accurate and precise instrument that was created expressly for this kind of measurement, is required for compliance with the standard since it is the method of choice for determining the luminous intensity of a light source. A goniophotometer of type C determines the luminous intensity of an object by pointing a light source in the direction of a detector and deter

  LM-79 Intensity measurements are luminous intensity (measured in candela) taken from various angles all around an LED light source. It can combine this group of candela values to calculate zonal or total lumens, which may be used to make illuminance predictions within an application. The LM-79 standard is used mainly for measuring light by how it is perceived by the human eye (photometry or photometric measurement). The standard outlines the testing apparatus, procedures, and circumstances it must follow to make precise and repeatable measurements of the amount of light produced by LED goods and the amount of electrical power such products use. Generally, it may break down the testing techniques into two categories: angularly scanned and integrated (also known as goniometer measures) and measurements that use integrating spheres. This standard's very first iteration had the number. LM-79-08, and it was released to the public in the year 2008. The updated version of the sta
