An Electrical Energy Conservation for 1200 Lux Illumination Football Stadium Using LED Floodlight

This paper presents an electrical energy conservation policy for 1200 lux illumination system of football stadium by using LED floodlight instead of metal halide floodlight. The standard stadium illumination accords to Asian Football Confederation Regulation. The stadium is located in Thailand. The standard stadium used for 11 player football. There are 4 galvanized steel poles with 35 meter high installed at four conner of standard. The initial design, 1500 W metal halide were selected. However,1200 W LED floodlight replaced to electrical energy conservation. The 42 luminaires were set on a pole. The characteristics of illumination were demonstrated by DIAlux program simulation. The illumination, uniformity values and electricity unit are considered. For the result, it can find that the LED floodlight can conserve the energy. The result of energy conservation is 181,440 Unit/year or 725,760 Bath.
