Product No: LSG-1200A
LSG-1200A Compact Goniophotometer is built-in 1-meter dark chamber. It utilizes a high-precision photometric probe to capture luminous intensity signals from light sources across various angles in 3D space via automatic dual-axis scanning. The system software automatically calculates photometric data—such as luminous intensity distribution, beam angle, luminous flux, and luminous efficacy—and supports the export of IES files for use in lighting simulation software like DIALux.
LSG-1200A Compact Goniophotometer supports synchronous photoelectric testing and allows for the connection of external AC/DC power supplies and electrical parameter analyzers; an optional CCD spectroradiometer enables an upgrade to a spatial spectral distribution testing system, allowing for the simultaneous acquisition of spatial color temperature and spectral data. Designed for R&D testing and type certification of LED modules, spotlights, and directional luminaires, the system complies with relevant standards such as CIE, IEC, EN and IES LM-79, making it suitable for corporate laboratories and third-party testing agencies.
Note: The LSG-1200A is intended only for light sources and luminaires with a light emission angle of ≤180° and is not suitable for 360° omnidirectional luminaires.
