HPG1900 test Principle：
Fix the detector and then rotation the lamps to reach measurement principle. The lamps are fixed in the two-columns working table, and then glow center of the lamps and rotation center of the working table should coincident by the laser aiming device. When the lamps rotate around the vertical axis, luminous intensity data of horizontal directions can be obtained; when the lamps rotate around the horizontal axis, luminous intensity data of vertical directions can be obtained. Both vertical and horizontal axis can continued rotate at the range of ±180°or 0°～360°. According to the lamps measure requirements, the system can achieve B-β、A-α or C-γ solutions. After luminous intensity data of all directions have been obtained, other photometry parameters can be work out by PC. In order to ensure the lamps are stable fixed, the system can be applied by two structures according to difference test solutions. The details as following:
1．Double columns structure (B-β and A-α solutions)
It is use to test Grille lamps and etc. when fix the lamps, make sure the glare center of lamps and rotation center of working stable are coincident. In B-β coordinate system, lamps axis and horizontal axis of working table should coincident. In A-α coordinate system, lamps axis and horizontal axis of working table should coincident. Shown in Figure 2-1
2．Single column structure (C-γ solution and Conical coordinate system)
They are used to test downlight, spotlight and etc. when fix the lamps; make sure the glare center of lamps and rotation center of working stable are coincident.
