According to the requirement of CIE, IESNA and national standards. We have achieved Type C measurement method through rotating photometer head. It is used to test the spatial light intensity distribution as well as various luminosity parameter for small indoor size luminaire.
Test report
>The detector rotates around the horizontal axis of tested luminaire.
>Rotation range: ±180 ° (or 0 °to 360 °)
>The tested luminaire remains static. It can achieve C-γ or B-β coordinate 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 :0.2° ,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 likeDialux.
