Integrating Sphere | Goniophotometer | Surge Generator | ESD Simulator - LISUN

The Illuminating Engineering Society of North America (IESNA) is the organization that developed and published the standard known as LM-75. These standard details the procedure for assessing the photometric performance of LED lighting products with the use of a goniophotometer. The standard is used extensively within the lighting industry for the purpose of evaluating the performance of LED lighting products with regard to the distribution, intensity, and homogeneity of the light produced by the goods. A goniophotometer is a device that is used to measure the light distribution of a light source by measuring the intensity of the light emitted at different angles. This is accomplished by measuring the light with the use of a device called a goniophotometer. In the instance of the LM-75, the measurements are collected at various angles along the vertical and horizontal axes. The findings are then used to compute the average and maximum intensity of the light, as well as the uniformity
