System Configuration A. Goniophotometric System:  Goniometric Rotating Console: 1) LSG-1890B: Japanese Mitsubishi Motor and German Angle encoder System to keep the test accuracy to 0.1degree 2) LSG-1800A: Taiwan Motor and Angle encoder System to keep the test accuracy to 0.2degree  The LSG-1890B has Goniometric Rotating Control Instrument in 19inch cabinet: It connects to the PC and was controlled by the software.  The LSG-1890B/LSG-1800A has Goniometric Rotating Control Android App which can control it to rotating angle in the dark room easily.  High Precision Photometer with Class A...

2. Working Principle Goniophotometric System carries out measuring methods of fixed location and rotating luminaries. The measured luminaries is installed on the rotating supported, the center of which is in line with the rotating supporter center with the help of Laser sight. The fixed photometry detector is testing the luminous intensity in various horizontal directions, while the light source rotating. The mechanical equipment allows turning the tested luminaries around a vertical axis and a horizontal axis. When the luminaries under test turn around horizontal axis, the detector which...

3. System Functions LSG-1890B/LSG-1800A Goniophotometer is high precision automatic goniophotometric instrument for luminous intensity distribution measurements with facility for turning the light source. The LSG-1890B uses a constant temperature detector, Japanese Motor and Germany precision angle coder which keep high test accuracy. It is for industrial laboratory measurements the photometric data of luminaries. Be utilized to measure photometric parameters of luminaries for LED road lighting fixture, room lighting fixture and projecting lighting fixture, such as spatial intensity...

Meets the requirements of CIE, IEC, IES LM-79 & GB standards Reaching many measurement ways such as B-βand C-γ Test Max Luminaires size and weight: LSG-1890B is 1900mm/60kg and LSG-1800A is 1600mm/50kg The tested luminaries rotates around an angle of (γ)±180°(or 0-360°) and the tested luminaries rotates around itself with an angle of (C)±180°(or 0-360°) Luminosity Testing Range: Illuminance 0.001lx~99,999lx; Light Intensity 1.0cd～107cd(detector) Photometry Accuracy: CIE Class A (Class L is option) Testing Accuracy: 2%(Under Standard lamp); Stray Light: less than 0.1% English version...

L=6*E (According to CIE, it requests at least 6times than the testing lamps).  Control Room size request: min=2000*2000*2000mm The wall, ceiling and floor should be all coated with dull black paint or be covered by black cloth and black carpet. Air-conditioner should be set in the dark room to control the temperature around lamps to the standard value upon the CIE requirements LISUN engineer dept will submit the Lab Design support documents according to the customer’s lab size after the purchase order was confirmed (The below are two Typical Lab Design reference for LSG-1890B/LSG-1800A)
