LED Sports Lighting as per EN12193 Standard

Nov. 30, 2022


All sports events require good lighting in order for the game to function properly, achieve the best possible results, and provide enjoyment for the participants and spectators present, whether they are watching the game on TV in the stadium or at home. Media coverage, especially TV coverage, is playing an increasingly important role in sporting events, which means that the need for light is not only for players and spectators, but also for cameras for better images quality. Finally, the stadium lighting should also limit excessive lighting, because these lights and cause bad interference to players, spectators, referees and the surrounding environment.


ZGSM believes that there are three main points of good sports lighting design. First, to ensure optimal visibility for participants and viewers (including TV viewers); second, to create a visually satisfying and interesting scene; third, to ensure a good integration of the lighting system with the surrounding buildings. So what factors do we need to consider to do this? This article will give the answer.

Common requirements for sports lighting

Whether it is an indoor or outdoor court, they should follow the requirements below. These include illuminance, uniformity, CRI, CCT and glare. We think these are what we shall be paid attention to at the beginning of lighting design, and a good lighting design will pay more attention to these aspects.


Illuminance(Average horizontal illuminance)

Illuminance refers to the amount of light (measured in lux) that the stadium provides to the teleportation. Generally the faster the movement and the smaller the moving object, the higher the required light level. Since different levels of competition require different illumination levels, lighting designers will recommend several different settings to enable the lighting system to be used at all levels, from training mode (non-television) to international competition mode (television broadcast). ). Illumination level includes horizontal illuminance and vertical illuminance, the former is required in most stadiums, and the latter is usually required in stadiums with television broadcasts.


Illumination uniformity

Illuminance uniformity refers to the ratio of minimum illuminance to average illuminance/maximum illuminance on a given surface. The larger the value, the more uniform the light distribution and the more comfortable the visual experience. There are generally two measurement methods. 1. Min/Average: This is the ratio of the minimum illuminance to the average illuminance; 2. Min/Max: This is the ratio of the minimum illuminance to the maximum illuminance. To create balanced lighting conditions, there needs to be enough uniformity so that people’s eyes and TV cameras don’t have to constantly adapt to different light levels.



CRI represents the quality of light and the ability of the light source to accurately reproduce the color of the surface being illuminated. The color rendering index (Ra) is used to describe the performance of a light source. Color rendering is expressed as a score from 0 to 100 Ra on the Color Rendering Index (CRI). The higher the CRI value, the better the light source’s ability to accurately reproduce the colors of the objects it illuminates. Usually the higher the level of the game, the more spectators or the broadcast of the game, which will require the lighting system to have a good color rendering. Generally, the color rendering index is calculated from the 8 values of R1 to R8. Usually, the CRI we say refers to this index. The Extended CRI rating adds R9 – R15 colors to the standard CRI samples.

Correlated color temperature

This is the surface color of the light source, which is different from the color rendering. Different color temperatures give different perceptions, usually warm (red) or cool (blue). Therefore color temperature is often described as “warm”, “white” or “cold”. Color temperature is defined in Kelvin (K). The lower the value, the warmer the color looks. For example, the 2700k has a warmer color appearance than the 4000k. The higher the value, the cooler the color looks, and this color temperature can make the players concentrate, so the stadium lighting generally chooses high and low temperature, such as 5700K.



Glare refers to visual conditions that cause visual discomfort and reduce the visibility of objects due to inappropriate brightness distribution or extreme brightness contrasts in space or time. “Glare” is a controversial issue, but there are mathematical formulas for calculating glare. Glare is usually a perception of light in the field of view that the human eye cannot adapt to and can cause disgust, discomfort and even vision loss. Uncomfortable glare on the court is caused by a certain point (lamp) being too bright, so we should pay more attention to the arrangement of the stadium lamps.
