What kind of lamps are suitable for stadium lighting, which requires us to return to the essence of sports lighting - functional requirements. For the sake of ratings, sports events are usually held at night, which is doomed that many venues are power-hungry, so energy saving has become The primary pursuit of venue lighting, when it comes to energy-saving products, LED lights are good. Compared with traditional light sources, LEDs can save 50% to 70% of energy. Traditional lamps such as high-power metal halide lamps have an initial output lumen of 100lm/W and The maintenance coefficient is 0.7 to 0.8, but most sites have a light attenuation of more than 30% after 2 to 3 years of use, which not only includes the attenuation of the light source output, but also includes factors such as oxidation, poor sealing performance, pollution, and respiratory system problems. , the actual lumen output is only 70 lumens/watt.
LED lights are suitable for stadium lighting with their unique features such as low power consumption, adjustable color quality, flexible control, and instant ignition. For example, our lighting stadium lights have an efficiency of 110-130 lm/W and a constant illuminance output of 5000 hours , which ensures constant illumination level and uniformity in the field, avoids the increase in the demand and cost of lighting equipment due to illumination attenuation, and reduces the power consumption of lighting equipment at the same time.
"People-oriented" is the purpose of lighting, and stadium lighting is no exception. A healthy light environment is necessary. In the lighting design of stadiums, glare and interfering light are the primary unfavorable factors that affect the level of athletes' competition, and also affect the quality of TV broadcasts. An important factor, glare is an important indicator that affects light health and light environment. Glare refers to the visual discomfort caused by the brightness contrast of inappropriate brightness distribution in space or time, reducing the visibility of objects. In the field of view, there is a kind of human eye. The sense of brightness that cannot be adapted may cause disgust, discomfort or even blindness. It also means that the brightness of the local area of the visual field is too high or the brightness changes too much. Glare is one of the important causes of visual fatigue.
