Stadium lighting cannot be ignored

0 Author 2021-01-29 17:45:25

Lighting can be the protagonist, or it can be used as a low-key auxiliary facility, such as a light show. The lighting is the protagonist doing your part. But more often, the lighting is only used as an auxiliary facility and is often ignored. Only when it has a problem, it will be caused. Pay attention. In the stadium, stadium lighting is often overlooked. For example, when a football player arrives on a football field, he is often concerned about whether the lawn of the football field is artificial grass or natural grass, and whether the size of the field is standard. Another example is a basketball player playing on a basketball court. He usually cares about whether there is water on the basketball court and whether the basketball hoop is deformed. They rarely notice stadium lighting fixtures. Only when the light of the stadium lighting fixtures dazzles your eyes or keeps flickering, you will notice it.

As an athlete, you can ignore the stadium lighting, and as a stadium investor, the stadium lighting cannot be ignored. Because stadium lighting is different from general home office lighting, the space of stadiums is relatively large, and the power of the lamps used is relatively large. The increase of power will increase the requirements for the lighting components a lot, such as heat dissipation. Lamp size, weight, etc.

The reason why the light dazzles your eyes is because the strong light directly hits the athlete's eyes, which is beyond his normal tolerance. The power of lamps in football fields ranges from two hundred watts to thousands of watts. There may be more manufacturers that can produce such high power, but there are not many manufacturers that can soften the light of such high-power lights. HISHINE stadium lighting lamps can be processed through optics to make the light softer, and the power factor remains greater than 0.95, the lamp efficiency is ≧170lm/W, which is green and energy-saving. The light of the stadium lighting fixtures is soft, which reduces a lot of unnecessary troubles in the construction. For example, the fixtures of the five-a-side football field are generally installed above 8 meters. Adjusting the projection angle can solve the problem of glare.

If the stadium lighting fixture keeps flickering, it is likely that the constant current power supply of the fixture has a problem, and the alternating current cannot be converted into a stable direct current. The high temperature is one of the reasons that affect the life of the stadium lighting power supply. The heat generated by high-power lamps is very large. Once the heat dissipation is poor, the temperature of the lamps will be too high, and the power supply connected with the lamp body will naturally be affected. The LED packaging technology of the lighting fixtures of the Huaxia Beidouxing Stadium is advanced. It provides a platform for LED chips, allowing LED chips to have better light, electricity, and heat performance, and allowing LEDs to have better luminous efficiency and a better heat dissipation environment. Moreover, the radiator adopts military-grade heat dissipation materials and structure, and the heat dissipation efficiency is extremely high.

I have encountered some sports players playing on the stadium, and always felt that something was wrong. I was always suspicious. Later I realized that it turned out that the color of the stadium lighting was wrong, and the chromatic aberration of the stadium gave the visual a strange feeling. The color temperature and color rendering index of stadium lighting fixtures can affect the color of the light, and then affect the vision of athletes. White light with different color temperatures gives people different feelings. The color temperature of the light source of warm white light is below 3500K, and the color of the light will be slightly biased towards yellow, giving a warm and warm feeling. The color temperature of the light source of cool white light is above 5500K, and the color of the light will be slightly biased to blue, giving people a cool feeling. The color temperature of the natural white light source is between 3500K and 5500K. Under this kind of light, the color of the object is more real. Maybe you are still relatively new to color temperature, but you should be familiar with sunlight. The light color of the sun during the day also changes with time: 40 minutes after sunrise, the light color is yellower, and the color temperature is about 3000K; the sun is white at noon, rising to 4800-5,800K, and it is about 6,500K at noon on cloudy days; the light color shifts before sunset. Red, the color temperature drops to 2200K for paper.

The color rendering index, as the name suggests, is the degree to which light presents the original color of things. The spectral power distribution of the light source determines the color rendering of the light source. The closer to the natural light spectrum, the higher the color rendering index.

 

The large power of stadium lighting makes it difficult to avoid its large size and heavy weight. For example, a 1000-watt lamp, its weight is often no less than 30 kg. Such a heavy lamp poses a great test for the physical strength of the lamp master, so how to reduce the weight of the lamp is also a problem faced by large lamp manufacturers. The lamp is bulky, so the matched lamp pole must be thick enough and the tube wall thick enough. This often results in sometimes, a lamp pole needs two cranes to be hoisted, and the construction cost will be relatively high. Therefore, the weight of stadium lighting is also a consideration when budgeting.

 

Although most stadium lighting fixtures have a warranty period of more than 5 years, some stadium lights are often replaced in two or three years. We encountered a customer who replaced the lights because his tennis court’s lights were blown by a typhoon. If it falls, the seine also falls to the ground. A little analysis will tell you the reason. The windward area of ​​the light pole and the fence is not large, so the main reason lies in the lamps. Many lamps are not small in size, and their faces are not small. For safety reasons, the choice of stadium lighting fixtures should avoid too large.
