Now there are many precision instruments that need very precise working steps. Although many automation devices have been realized to greatly improve the efficiency and accuracy of work, supervision and inspection are still needed, so good lighting systems are needed in these workshops. Extreme high illumination requirements Brightness is to ensure that our line of sight, the closer to the illumination of the sun, the object of the reduction of the better, so not only the brightness can meet the standard, also need to show high finger to support. Only in this way can the work efficiency of the precision…
