How to design an excellent football stadium lighting?
What are the key points of an excellent football stadium lighting design?
First, be bright (sufficient brightness). This is a constant core of lighting design. In fierce competitions, the speed of football is very high, and football players run faster. For football players to see the ball and people clearly, it must be bright. More importantly, the camera must be able to capture clearly visible scenes and facilitate high-definition live broadcasts, so that many people in front of LCD TVs or computers can also see the exciting competition clearly.
From the table below, we know that the vertical brightness must achieve 1000-2000lx. It is actually determined according to the needs of the parties involved, usually to achieve the highest standard, and then use system control to adjust different lighting effects according to different competition needs.
Second, the brightness should be evenly distributed. In other words, the light spots on the ground will not be too conspicuous, and the uneven distribution of brightness will cause dry eyes and affect the quality of the competition.
Third, choose the CRI and color temperature of the light source reasonably and effectively.
A. The full name of the light source's rendering index is the color rendering index, which means the level of the color tone of the light source restoration object. The larger the value, the better the actual color tone of the object. In general competitions, the CRI must exceed 80, and for national and world-level competitions, the CRI must exceed 90.
B, the color temperature of the light source, in simple terms, is the live broadcast of the cold and warm light source. The lower the color temperature, the more yellow the light source, and the higher the color temperature, the more blue the light source. The color temperature of the competition is usually 4000K or higher. In addition, in order to meet the needs of high-definition live broadcast of the camera, the color temperature is usually ≧5500K.
Fourth, we must strictly control glare. The greater the glare value, the more dazzling the lighting and the more uncomfortable it is. From the first table, we all know that the glare will not exceed 50.
How can we reduce glare?
The most important thing is the way of lighting fixtures. The lighting fixtures of the competition are usually placed on the left and right sides, so that the glare can be better adjusted. In addition, the selection of lamps. It is necessary to choose lighting products with good light distribution, low glare and high quality.
Fifth, there must be reasonable atmosphere lighting.
With the improvement of many people's appreciation level, not only the sports venues need to be bright, but also beautiful. This requires the addition of corresponding ambient lighting to achieve this requirement.
In summary, an excellent football stadium lighting must achieve five points: bright (sufficient brightness), uniform brightness distribution, reasonable and effective selection of the color rendering index and color temperature of the light source, strict control of glare, and a reasonable atmosphere Lighting
