GPM-1800B LAMPS AND LANTERNS ROTATING GONIOPHOTOMETER

According to the requirements of CIE, IESNA and national standards, we have achieved many kinds of testing methods such as B-β、A-α and C-γ through rotating lamp.

 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 contains spatial light intensity distribution, curve of intensity distribution in any cross section(show it either with rectangular coordinate system and polar coordinates system), spatial equivalent  light intensity  curve, distribution curve of planar equivalent illuminance, curve of  brightness limition, hoop luminous flux, glare rank, efficiency of lamp, effective blazing angle,  ratio of light track for upper shoot, ratio of light track for low shoot, total luminous flux, effective luminous flux, useful modulus, electric parameter(voltage ,current,power and power element) and so on. it can work either with double frame and single frame

◆ Rotations of test samples around both vertical and horizontal axis,and rotation range: ±180°(or 0～ 360°)
◆ The testing methods of single strut drive C-γ coordinate system and double strut drive C-γcoordinate  system
◆ special collimation device with laser cross line, expediently and  truely fix the position of the test  luminaires
◆ Using technical and high level redirector which is made up by noble metal, no winding, intelligent start and stop
◆ Keep the moving very stable, speedy and low noise.
◆ The accuracy of angle : 0.1° , resolution of angle : 0.01°
◆ Accuracy of photometry : CIE class A (standard class)
◆ The tested data meets the international and national standard requirements. IESNA file format output  can be transfered by other illumination and luminaire design  software
◆ RS-232C standard interface and windows operating  boundary surface with both Chinese and English, convenient to connect with all kinds of computers
