LED Lighting Assessment for High-Performance Stadium Illuminance

The usage of LED lighting has been commonly used in indoor and outdoor to facilitate energy-efficient. Because of its characteristics that relatively consume less energy compared to other traditional forms of lighting, it is considered the best alternative to be used as a lighting source. LED lighting also can be applied in stadium lighting applications. The lighting requirement for a stadium is exceptionally high. It requires many luminaires to be used to meet these specifications. The specifications consist of several parameters that inter-related that will affect the performance of lighting. Besides, a different type of view angle of a luminaire will give a different visual performance. Due to this challenge, it requires thorough work being done during the design process as well as during the installation process. The luminaires need to be aimed at proper aiming point coordinates to meet the specifications. Hence, a study on the characteristics of LED lighting needs to be done. In this paper, the objective is to model the output from LED lighting and study the effect of tilt angle and view angle of the luminaire on the visual performance of stadium lighting. A computational model of LED luminaire was developed using MATLAB. With the developed model, the effects of different tilt angles and a different beam angle of luminaire were investigated.
