In the formula: the vertical subtended angle of β-projecting beam, h
1-projecting beam the height in vertical direction that records by illuminometer in the A position, h
2The height of-projecting beam the vertical direction that records by illuminometer in the B position, d-be the distance between A and the B two positions.
11. measurement mechanism according to claim 8 is characterized in that to the measuring method of the space luminosity distribution character of aiming lamp box the axis of 2 adjacent aiming lamp boxes (2) is that the vertical subtended angle center line angle theta of projecting beam is determined by following formula:
In the formula: O
