Power and energy since most movements include observations of fast moving objects, such as baseball or ice hockey stadium lighting, sports venues usually requires a high degree of illumination, ranging between 300-1500LX (30-150FC).
The illumination load requires high power density (watts per unit area), high power demand (kw), and high energy consumption (kwh) in some equipment due to long operation. It is noteworthy that energy is consumed only when the system is operating. For the main sports lighting systems, the illumination load may have the short-term high power demand requirement, therefore has the very low energy consumption. For example, a professional stadium as a professional baseball and football field lighting may require 700 1500W of metal halide lamps to illuminate.
The power requirement is close to 1130-kilowatt. If the work plan of the playground is a 40-game average of 5-hour night games, the annual energy consumption of its illumination is in this range: 1130*40*5=226000 kwh. In comparison, a city park may consist of 4 softball fields, with only 240 1000 watts of metal halide lamps illuminated. The required power requirement for lighting is only 260-kilowatt.
However, the operation plan of a standard complex may be 200 nights a year, averaging 5 hours per night. The annual energy consumption resulting in field illumination is 260*200*5=260000 kwh. For each professional playground, there are hundreds of parks and municipal recreational facilities. The energy consumption of these entertainment equipment is much larger than some sports fields.
