1.System Configuration A. LSG-2000 Goniophotometric System:  Goniometric Rotating Console: Japanese Mitsubishi Motor and German Angle encoder System to keep the test accuracy.  High Reflective Moving Mirror: Special design and produced to keep high reflective value.  Goniometric Rotating Control Instrument in 19inch cabinet: It connects to the PC and was controlled by the software.  Goniometric Rotating Control Instrument in dark room: This can allow the customer to control the rotating in the dark room when install the lumainires but no need to control in the PC.  Double Channel &...

2. Measurement Principle Goniophotometer with Moving Mirror (also called Goniphotometer with Rotating Mirror) can test luminaries rotating in the prescribed burning position and around the vertical axle and a reflecting mirror rotates around the horizontal axle, meanwhile, a synchronous axle will rotate toward the opposite direction synchronously. The photometer head located at a fixed position of the limiting photometric distance in front of the reflecting mirror to gather the light in each direction. The rotation priority is determined by the software. If mirror axle is took precedence of...

The LSG-2000 fully meet LM-79 Clause 9.3.1, CIE and GB standards for Goniophotometric of luminaries, this system is used to measure spatial luminous intensity distribution of luminaries for floodlight, street lighting and interior lighting, and other photometric parameters such as spatial iso-intensity curve, intensity distribution curve of each section (shown in rectangular coordinate system or polar coordinate system), iso-illuminance distribution curve, luminance limitation curve, luminaries efficiency, glare grade, effective beam angles, upward luminous flux ratio, downward luminous...

Room Requirements according to CIE Operation Room(W*L) The dark room wall, ceiling and floor should be all coated with dull black paint or be covered by black cloth and black carpet. Air-conditioner: be set in the dark room to control the temperature around lamps to the standard value upon the CIE requirements. Note: LISUN GROUP engineer dept will submit the Lab Design support documents according to the customer’s real lab size after the formal purchase order was confirmed Fig: LSG-2000 lab dark room view

Requirements of Eliminating the stray Light Luminaires must be where the photodetector can only receive the light reflected by the rotating mirror in the LSG-2000 system. The light given off directly by the luminaries and reflected by the wall and floor is warded off by the light fence. Internal surface of the dark room and dark path together with the surface of the light fence should be painted unpolished black or be covered by black cloth and black carpet. 3) Temperature around the lamp or luminaries must be 25℃±1℃ during the test. Exceptions can be given according to relative lamps as...

7. Design Standard of Device The construction, technical parameter, test & operate steps as well as data processing software of LSG-2000 Goniophotometer with Moving Mirror meet the following requirements: 3.1 CIE Pub. NO.70,”The Measurement of Absolute Luminous Intensity Distributions” 3.2 CIE DIV.Ⅱ-TC10,”Photometry of Luminaires” 3.3 IES LM-35-1989,”IES Approved Method for Photometric Floodlights” 3.4 IES LM-31,”IES Approved Method for Photometric Testing of Roadway Luminaires” 3.5 IES-LM-79, “Electrical & Photometric Measurements of Solid-State Lighting Products” 3.6 GB/T...
