Goniophotometers are precision instruments designed to measure the spatial distribution of light emitted from luminaires, LEDs, and other light sources. These devices provide critical data on luminous intensity, flux, and angular light distribution, enabling manufacturers and researchers to evaluate performance, compliance, and optimization of lighting systems. The measurements adhere to international standards such as IEC 60598, IEC 61341, CIE 70, and LM-79, ensuring consistency across industries. <\/p>\n
This article examines the technical principles, key features, and applications of goniofot\u00f4metros<\/a>, with a focus on the LISUN<\/a> LSG-6000<\/strong> goniofot\u00f4metro<\/a><\/a> system. <\/p>\n Goniophotometers operate by rotating a light source or detector along one or more axes to capture luminous intensity at varying angles. The two primary measurement configurations are: <\/p>\n O LSG-6000<\/strong> employs a Type C configuration with a high-precision robotic arm, ensuring minimal measurement uncertainty (\u00b12% for luminous flux, per IEC 60598). <\/p>\n O LSG-6000<\/strong> is engineered for high-accuracy photometric and colorimetric testing, with the following specifications: <\/p>\n Goniophotometers verify compliance with energy efficiency regulations (e.g., EU Ecodesign Directive) and optimize light distribution for LED modules.
