GPM-1800B Lamp and Lantems Rotating Goniophotometer

According to the requirements of CIE, IESNA and national standards, we have achieved  testing methods as B-β、A-α and C-γ through rotating lamps. It is used to test the spatial light intensity distribution as well as variety luminosity parameter of indoor spotlight, cast light lamp and street light. It can work either with doublearm or single arm.

Principle

During the test, detector remains static, tested luminairerotates around the γ axis and C axis and achieve the full spatial intensity distribution.

Characteristics

○ Rotations of test samples around both vertical and horizontal axis,and rotation range:±180°(or  0～360°).Single 

   arm for C-γ measurement. Double arms for B-β measurement.

○ Using high level redirector made up by special metal fiber,no winding,intelligent startup and stop,keep stable 

   rotating, continuous testing  and low noise.

○ The accuracy of angle :0.1°,resolution of angle :0.01°.

○ The accuracy of  photometric:standard class.

○ The tested data meets the international and national standard requirements.Test result can be output with IES,IDT,

   CEN,CIB, CSV.TM4,CIE files and directly used by design software like Dialux.
