Lighting in Sports Architecture

by RESH

In Sports LED lighting there are specific requirements that may not be familiar to many lighting designers. During the design process it is important consider the following :

Uniformity : Easily explained as lighting spread evenly in a given area. It enables both the players and the spectators to easily follow the action, and it provides consistent lighting for the television cameras and photographers. Uniformity U0 is defined as the quotient Ēmin/Ē of minimum and average illuminance in the visual task area. The closer to 1 the better the uniformity.

Color : Colour measured in CCT , Correlated Colour Temperature. Many sports organizations specify the allowable correlated color temperature, designated CCT, for sports field lighting. For eg FIFA requires a cct ≥ 4000K & NFL requires 5600K (alternatively 5000K to 7000K).

Light Polution : Light pollution from stadiums and sports fields can be a concern, particularly for surrounding residential neighborhoods. This includes not only light that is reflected from the ground and illuminates the sky overhead, but also light trespass and glare from improperly shielded luminaires.

Visual Glare : Glare is the loss of visual performance or discomfort produced by an intensity of light in the visual field greater than the intensity of light to which the eyes are adapted. Simply put, glare occurs when too much light enters your eye and interferes with your eye’s ability to manage it. While it cannot be directly measured in the field, a glare rating metric, designated GR, can be calculated.

Type of Luminaire : In selecting the right type of LED lighting for ligthing designs we should consider the following prerequisites :

  1. Higher Efficacy : Lm/w , Lumens per watt
  2. Good reliable LED Chipsets.
  3. Good reliable DRIVERS.
  4. Certifications ( TUV, CE.. )
  5. IP ratings

I look forward in explaining these considerations & more . See you good people soon !
