Selon les exigences de la CIE, de l'IESNA et des normes nationales, nous avons réalisé des méthodes de test comme B-(B、Aa et Cy à travers des lampes rotatives. Il est utilisé pour tester la distribution spatiale de l'intensité lumineuse ainsi que le paramètre de luminosité de la variété du projecteur intérieur, lampe à lumière coulée et réverbère.

Technical support features:
The main shaft and lamp shaft adopt the conductive slip ring with precious metal optical fiber point brush structure, which can run 360 degrees continuously without backlash for measurement. There is no need to rotate back and forth to prevent winding, and never winding;
Adopt a well-known brand of high-speed, high-torque, low-noise, low-vibration three-phase hybrid stepping motor;
It has a laser sight to make the center of the lamp under test coincide with the center of rotation of the rotating table;
Vertical axis rotation range: -180°～180° or 0°～360° rotation;
Horizontal axis rotation range: -180°～180° or 0°～360° rotation;
