In stadiums, lighting plays a pivotal role in the experience of athletes and spectators. Therefore, choosing the right luminaire is a top priority.
The common lamps in stadiums have the following types: such as halogen lamps, halogen lamps are a kind of traditional stadium lights, which are gradually eliminated by the society due to their high energy consumption and long time to turn on the lights; And the current mainstream is LED lights. LED lamps have the characteristics of high brightness, low energy consumption, long life, etc., and can provide high-definition lighting effects.
The high brightness of LED lighting can effectively improve the lighting effect of the stadium. LED luminaires have a large amount of light and can evenly shine the light throughout the stadium, so that both athletes and spectators can clearly see the progress of the game. In the heat of the game, bright lighting can enhance the concentration and reflexes of the players, and improve the competitiveness of the game.
Secondly, LED lighting has excellent energy-saving and environmental protection characteristics. Compared to conventional lighting, LED luminaires can significantly reduce energy consumption. This is especially important for stadiums, which tend to run for long periods of time and the high power consumption of traditional lights puts a huge burden on the stadiums. The use of LED lighting not only reduces energy waste, but also saves considerable operating costs for the venue.
At the same time, the long life of LED lighting reduces the frequency of lamp replacement. Traditional light filaments are prone to breakage and need to be replaced frequently. The LED lamps use solid-state light sources, which have a long service life and reduce the burden of venue maintenance.
Only by choosing the right luminaires can you provide quality lighting and enhance the experience of athletes and spectators, while reducing operating and maintenance costs.
The lighting of stadiums should not only meet the standards of various stadiums and various levels of events, but also pay great attention to the actual effect of real-time broadcast on color TV. In order to ensure that the broadcast images are vivid and clear, and the colors are true, there are corresponding regulations on the vertical illumination, the uniformity of light intensity and the three-dimensional sense of space, the color temperature and color rendering index of the light source, and the lighting standards of different levels of stadiums are different.
From professional sports competitions to amateur training, LEDs enhance broadcast effects by eliminating strobe, slow-motion replays. Equipped with professional LED sports lighting, the balance between warm and cool colors can be eliminated, shadows, glare or black spots can be eliminated, and the picture seen from the TV is clear, and every second can be clearly captured by the agile movements of the athletes.
Stadium lighting fixtures should have anti-glare measures. Luminaires should come with their own or come with an indication device for adjusting the angle. The protection level of the lamp housing should preferably be above IP65. Lamps and their accessories should have anti-fall measures, and the locking device of lamps and lanterns should be able to withstand the wind load under the conditions of use.
Narrow beam 10~45 and medium beam lamps should be used for outdoor stadiums, and medium beam 46~100 and wide beam lamps should be used for indoor stadiums.
In the field of sports lighting, the stadium lights have excellent light output, advanced heat dissipation system, excellent optical design and other characteristics, through scientific and reasonable lighting layout, can ensure the excellent lighting effect of the venue, greatly eliminate glare interference, reduce the light pollution of the surrounding environment as much as possible, and create a comfortable and pleasant lighting environment for athletes and spectators.
A good stadium should use good lighting fixtures, because it not only has to meet the requirements of athletes on the field for competition and audience viewing, but also sometimes to meet the requirements of color temperature, illumination, illumination uniformity and so on for live TV broadcast and broadcasting, which is far higher than the requirements of athletes and spectators.
What is the good of stadium lighting for professional sports lighting? There is no doubt that they are specially tailored for court lighting, such as football field lights, basketball court lights, badminton court lights, tennis court lights, table tennis court lights……
Then the question arises, what is the custom for the stadium lighting? It depends on what the lighting requirements of the stadium are. Here is a brief list of several important requirements and standards for sports lighting.
- Requirements for the color rendering index of the light source of the lamp for sports lighting
The color rendering index is a measure of the ability of a light source to display the original color of an object. Sunlight has the most realistic ability to render color to objects, and can be used as a reference light source and as a reference standard. The International Commission on Illumination (CIE) has set the color rendering index of sunlight at 100Ra and specified 15 test colors, which are represented by R1-R15. The color rendering index is divided into 5 grades:
90-100Ra: Places where accurate color contrast is required;
80-89Ra: a place that satisfies the correct judgment of color;
60-79Ra: places that meet moderate color rendering;
40-59Ra: places with low requirements for light color rendering and single hue;
20-39Ra: Places where there are no specific requirements for light color rendering.
The stadium is not a monochromatic venue, so the minimum level of display index required for stadium lighting is greater than 65Ra. If it is a large stadium and needs to be broadcast on TV, the color rendering index needs to be greater than 80, and the highest level of stadium lighting – HDTV broadcast is significant, and the requirements for the color rendering index of international competitions are higher, more than 90Ra. Therefore, the color rendering index of the stadium special lamp needs to be at least 65Ra or more, and the color rendering index of our stadium special lamp is more than 90Ra, and the high color rendering index is one of the advantages of the professional sports lighting brand stadium lamps.
Second, the requirements of sports lighting for the color temperature of the light source of the lamp
The color temperature of light can bring people a feeling of warmth and coldness, the light emitted by the light source with a color temperature below 3500K is called Warm White, the light emitted by the light source between 3500K and 5500K is called Natural White, and the light emitted by the light source above 5500K is called Cool White. What is required in sports lighting is natural white light, such as table tennis court lighting, billiard court lighting, the color temperature required is 4000K, and the color temperature of football fields and basketball courts is between 4000K-5500K. The color temperature of our stadium lights can be customized according to the specific stadium lighting requirements. The color temperature can be customized at will, which is also one of the advantages of professional sports lighting brand stadium lamps.
- Requirements for glare control in sports lighting
Glare is what is commonly referred to as dazzling and dazzling light. In the lighting of this stadium, the glare index is used to measure the degree of dazzling lighting. If the glare of the stadium lighting is severe, it will seriously affect the vision of the athletes, causing their strength to not be able to play normally, and over time, it will also affect the physical and mental health. The impact of glare on the referee is equally important, because the referee cannot follow up every detail of the game normally due to the illumination of the light, which will cause misjudgment and affect the normal progress of the game. Glare can also be inconvenient for spectators. If the glare value is too high, it will have a glare effect in multiple locations and different angles of the stadium, and the players and balls seen by the audience will be covered with a layer of white light, and the vision will be blurred. Similarly, the photos taken are also white, and the ornamentation is greatly reduced. The video that was filmed, not to mention. For example, the light source of Huaxia Beidou Planet Field lamps and lanterns adopts high-quality high-power lamp beads, with high brightness, softer light, light color and stadium integration, and has 144 kinds of light distribution curve technology, precise control of light, which brings convenience to the design of lighting schemes, so that the horizontal illumination of the stadium in 2000lux can also control the glare value below 50.
Fourth, the requirements of the contrast degree of sports lighting
A stadium is often not equipped with only one light, so the illumination of a stadium is often determined by multiple lights. This poses a number of problems. How much power to use, how many lamps to use, how high to hang, how to put the angle, and so on, each of which has a great impact on the budget. For example, the efficiency of the Beidou Planet Field in China is as high as 110-130 lm/W, which can directly replace traditional lighting products such as metal halide lamps to achieve the effect of green, energy-saving, healthy and environmentally friendly, and can achieve the same stadium lighting effect with lower power and fewer lamps.
