first, uniform illumination pavement uniform illumination, said the road is also useful area of uniform illumination. Big power, high lumen is a useful area of uniform illumination in order to progress. Just right the right of uniform illumination should be no less than practice.

the second device, device distance and right right right or less than the practice, this is a unit is inversely proportional to the distance with uniform illumination, when device is 20 meters distance, for instance the uniform illumination is 30 lx, so if the device when the distance to 40 meters, uniform illumination is 15 lx.
