Products Name:luminaire goniophotometer
Quantity: 1 suit
Model Number:HPG1900
Place of Origin:Hangzhou, China
Goniophotometer is designed for all kinds of lighting fixture, like floodlights, spotlgithts, dowlights, indoor and outdoor luminaires to measure the spatial luminous intensity distribution curve, section intensity distribution curve, isolux distribution curve, brightness limitation curve, zonal luminous flux, luminous efficiency, glare grades, total luminous flux, efficiency luminous flux, utilization factor and electric parameters. The test can be fulfilled with B-��, A-��and C-��methods according with different type of lighting fixtures; test principle can completely meet the CIE 70, CIE121 and GB requirements; test process is controlled by software automatically, all the data can display in software and save as EXCEL and PDF files, the most important is that the software can output the IES file to meet the international standard, so that avail to other lighting software.
Requirements about the dark room:
This system needs the support of a dark room which dimension is 3m (width)*3m (height)* 10m to 30m (length), the ceiling, wall and floor should be black drew. The temperature of the dark room should be controlled by an air condition to keep constant temperature to achieve CIE requirements.
The system consist by rotation working table, photodetector, goniophotometer controller, digital power meter, AC power source, instrument cabinet.
