Question 1

What is uniform lighting?

Accepted Answer

Light uniformity, also known as uniformity of illumination, is a measure of how evenly light is distributed over an area. It is also a description of the smoothness of the lighting pattern, or the degree of intensity of the light and dark areas in the area to be illuminated.

Question 2

What are U0 and UI in Lighting?

Accepted Answer

Different lighting levels have different lighting standards. They are: Average Luminance (Lave), Overall Uniformity (U0), Longitudinal Uniformity (UI), Disabling Glare (TI), Surrounding Illumination (SR). U0=Emin/Eav, UI=Emin/Emax,they are measures of how evenly light is distributed across the road.

Question 3

How high the uniformity is appropriate?

Accepted Answer

The human eye takes some time to adjust to different light levels. Therefore, uniform illumination is required in the illuminated area. The uniformity of the working area is recommended to be greater than 0.60. Because, above this level, people cannot perceive the change in light level, which makes them feel comfortable. In the road area, the lighting requirements of M4 stipulate that overall uniformity (U0) >0.4 and longitudinal uniformity (UI) >0.6
