High Precision Rotation Luminaire Goniospectroradiometer

LSG-1800ACCD / LSG-1890BCCD High Precision Rotation Luminaire Goniospectroradiometer employs a testing principle in which the detector remains stationary while the luminaire under test rotates. The system consists of a goniophotometer main unit integrated with a high-precision CCD spectroradiometer. The luminaire can rotate continuously from -180° to +180° along both horizontal and vertical axes, supporting measurement modes in both C-γ (single-arm configuration) and B-β (dual-arm configuration) coordinate systems. The LSG-1890BCCD is equipped with a temperature-stabilized photometric probe, Japanese Mitsubishi servo motors, and high-precision German angle encoders. A laser alignment device ensures that the center of the luminaire coincides with the center of rotation, providing precise angular positioning and guaranteeing high accuracy and repeatability for full-space photometric testing.

High Precision Rotation Luminaire Goniospectroradiometer

LSG-1800ACCD / LSG-1890BCCD High Precision Rotation Luminaire Goniospectroradiometer with spectral distribution measurement capabilities is designed for a wide range of lighting products, including LED luminaires, horticultural lighting, HID lamps, and fluorescent lamps. It is suitable for R&D, performance verification, factory quality control, and third-party compliance testing. The system includes professional testing software (available in both Chinese and English) that supports the export of spectral data and industry-standard photometric file formats (such as IES and LDT). It integrates seamlessly with lighting simulation software like DIALux and enables the measurement of spatial color distribution as well as PAR/PPF/PPFD spatial distribution for horticultural lighting, ensuring compliance with both domestic and international (European and American) standards for integrated photometric and colorimetric testing.
