According to the requirements of CIE, IESNA and national standards, we have achieved testing methods as B-(B、A-a and C-y 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 double arm or single arm.
During the test, detector remains static, tested luminaire rotates around the y axis and C axis and achieve the full spatial intensity distribution.
● Rotations of test samples around both vertical and horizontal axis,and rotation range:±180°(or 0 ~ 360°)
●The accuracy of angle :0.1°, resolution of angle :0.01°
●Single arm for C-y measurement. Double arms for B-3 measurement.
●The accuracy of photometric:standard class.
●intelligent startup and stop , keep stable rotating, continuous testing and low noise.
●The tested data meetsthe 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.
