LED Sports Light Design Statement

Time:2014/9/15  keywords:LED Sports Light


      The ability to broadcast events with the best possible lighting will ultimately showcase these events to mass audiences around the globe. Professional athletes, broadcast cameras, game officials and spectators are all impacted in some way by the  LED Sports Light   during an event. Consequently, many complex considerations and decisions are involved in creating a design of the lighting system to ensure the objectives are met.


      ME Engineers has developed this design criteria to fulfill the lighting requirements for NFL games. The proposed criteria has been developed based upon established guidelines in addition to ME Engineers experience of successful LED Sports Light design at other world class venues around the world.


      The design has been progress to point that the new light fixtures are generally located in the same locations as the existing light racks. The lighting fixtures shall be positioned to provide a high quality of illumination and uniformity. The manufacturer proposed lighting solution shall meet the criteria stated herein including the needs for UHD and HDTV with current super slowmotion, flicker free replay as well as the needs of 4K and 8KTV.


      In regards to illumination levels there are two main criteria, horizontal and vertical. Horizontal illuminance is a measure of light reaching a horizontal plane, 3 feet above the playing surface. A grid across each playing field shall be used as a basis for collecting these measurements and calculating maximum/minimum/average illumination on each field of play. (Refer to Appendix A for Audit Grids)


      Vertical lighting at field level is the amount of illumination reaching the vertical surface of the players. This illumination helps to show close-up details of players, particularly their faces, at critical moments during the game. These images are captured by (both hand-held and motorized) field camera positions. Vertical illumination is important for both participation and spectators. The vertical illumination and uniformity requirements for broadcast television cameras are quite onerous, for HDTV and current super slow motion equipment.


      As such, the manufacturer’s proposed lighting system must take into consideration the complex requirements of the professional athlete performance by minimizing distracting glare and insufficient illumination across the field of play. In addition, the lighting system must have high visual comfort for the spectator to see the performance of the game and the ability of the broadcast camera to show the best digital picture quality for slow motion and close up shots of the performance.
