High Precision Rotation Luminaire Goniophotometer – Full Spatial Light Distribution Testing

High Precision Rotation Luminaire Goniophotometer – Full Spatial Light Distribution Testing: Measures light distribution and photometric properties of luminaires.

LSG-1890B/LSG-1800A goniophotometer is automatic goniophotometric instrument for luminous intensity distribution measurements with facility for rotating the light source. The LSG-1890B/LSG-1800A uses a constant temperature detector, Japanese motor and German precision angle coder which keep the test results with high accuracy. It is for industrial laboratory photometric data measurement of all kinds of luminaries such as LED luminaries, HID lamps, fluorescent lamps and so on.

Selecting a high-precision goniophotometer for full spatial photometric testing requires careful evaluation of mechanical stability, angular resolution, and detector calibration. The system should comply with CIE S 025/E:2015 and IES LM-79 standards, offering ±0.1° angular accuracy and a dynamic range capable of measuring both low-lumen decorative fixtures and high-output industrial luminaires. Key features include dual-axis rotation (Type A, B, or C per CIE classification), temperature-controlled mounting to simulate real-world thermal behavior, and a spectroradiometer with NIST-traceable calibration for accurate CCT, CRI, and luminous flux data. Suppliers should provide full uncertainty budgets, regular recalibration services, and software compatible with common lighting design platforms (e.g., AGi32, Dialux). Ideal applications include R&D validation, energy efficiency certification (ENERGY STAR, DLC), and compliance testing for global markets (EU Ecodesign, California Title 20). Ensure the chamber size accommodates your largest fixture and that stray light is minimized through baffled optical paths. Prefer vendors offering on-site installation, operator training, and integration with automated test sequences to enhance repeatability. Long-term reliability hinges on robust bearing systems and environmental shielding against vibration or ambient light interference. (for reference only)
