What Are The Lux Level Of Sports Venue?

The level of Sports venue illumination that is appropriate for a particular sport should be checked with the requirements of the National Governing Body(NGB) or the organization that is promoting a particular event. This can vary with the level of play and competition. 

Verification that minimum standards are being achieved can be a requirement for each individual event, as in the case of hockey. The CIBSE Lighting Guide 4 2006 and BS EN 12193:2007 give general recommendations for the

range of sports lighting standards. However, it should be noted that in some cases, these differ from the requirements of the NGBs requirements as noted in Appendices 3 and 4.

Glare

The complete elimination of glare in sport is difficult to achieve due to the ever-changing directions of view of participants. Nevertheless, measures should be taken to minimize glare that may affect the visual performance of participants.

When attempting to minimize the likelihood of glare, the factors over which a designer has control are;

•Selection of luminaires designed with attention to the avoidance of glare.

In designing a luminaire, there are two main methods of avoiding causing glare, which is O to make any direct view of the light source impossible by placing it deep within the luminaire, behind baffles O to use low-intensity light sources, such as fluorescent tubes.

The locations of the luminaires.

Where possible, luminaires should be located in positions which mean that players will not need to look towards them or in their general direction in the course of a game, for example behind the badminton baseline. 

Lighting levels for outdoor sports lighting are considerably lower than daylight levels and usually lower than for the same sport played indoors. This is because there is generally greater subject contrast outdoors, with a dark sky backdrop, giving good adaptation levels. Illuminance levels are dependent upon the difficulty of the visual task.

Guide to sports lighting levels

In general, fast action, a small playing object (cricket ball) and long viewing distance will require high lighting levels. A slower speed, larger playing object (football) and closer viewing distance will require lower lighting levels. Exterior sports lighting is provided to achieve either supervised training, club, national, international or CTV coverage.

Various lighting guides and lighting specifications are available, recommending appropriate illuminance levels for individual sports. Within Europe, a European Standard exists covering minimum sports lighting levels EN 12193:2007. In addition many sports governing bodies also provide separate specific lighting requirements. 

Most recommendations of individual sports lighting levels are divided into classes of play:

Class I - Top Level Competition.

Class II - Intermediate Level Competition.

Class III - Lower Level Competition & Supervised Training.

Lighting for CTV broadcasting has specific requirements and recommendations (CIE No.83:1989).

The table below provides a selection of recommended lighting levels for principle sports in accordance with EN 12193:2007.
