Uniformity is the ratio of the minimum lighting level to the average lighting level in a specified area. … A working environment with a 0.60 ratio is one in which people don’t notice different lighting levels with the naked eye and feel themselves in an environment in which light is well-distributed.

How do you increase uniformity in lighting design?

The illumination uniformity in the space lighting can be effectively enhanced by adjusting the curvature of lens, and the curvature was set less than 1mm. By readjusting the intensity in each angle, the candela distribution of the redesigned flat panel light is shown in Fig.

How do you get uniformity?

Calculate the average of all of the measurements (total average or AvgT). Divide the average of the lowest quartile (AvgLQ) by the total average (AvgT) to get distribution uniformity (DU).
