The lighting design of sports venues such as table tennis, badminton, volleyball and basketball should pay attention to the dynamic factors in the light environment.

The physiological and psychological effects produced by the stadium lighting will eventually form the psychological preference of the people who play in the stadium.

There are four light physical elements that should be deeply grasped in the construction of the lighting environment of the stadium.

The venue's light environment is a system that includes several quality elements of sports lighting, as well as venue lighting design and lighting pattern elements.

The main photophysical elements of the site lights are light color, color rendering performance, glare effect, and stroboscopic effect. The main technical elements of the venue lighting design and lighting mode are the site horizontal illuminance value and the sky vertical illuminance value and illuminance uniformity.

Photophysical element 1: 

sports lighting color. Currently used in badminton, table tennis, basketball, volleyball, football, etc., stadium lighting for sports venues.

The light color of the stadium lights is different. Some are the color of the sun, pure white is bright, clear and comfortable. Some deviate from the sun color, although it is also white light, but the venue lights white with blue-green, the effect of glare is more powerful. Some are white light, but they are not the color of the sun. They contain more blue light energy, and the glare effect of the light is serious.

It should be noted that many white light looks not necessarily the sun. The white light of high color temperature looks like the sun, but the essence is not the real sun.

Then, like the badminton hall, table tennis hall, basketball hall, volleyball and football stadium lighting, what kind of light color should the venue lighting be?

According to the observation, the successful experience of many high-end sports venue lighting is proved. The lighting of the stadium lighting should be the color of the sun, which is equivalent to the sunlight from 10 am to 3 pm, pure white, bright, clear and comfortable. If you use the concept of color temperature to describe the color of light, the color temperature of the stadium lighting should be around 6000K, preferably not higher than 6200K, and should not be higher than 6500K.

Photophysical element 2: 

Stadium lighting should have high color rendering performance. The color rendering performance of the venue lights is an important physical and optical element that affects the quality of the venue lighting. The higher the color rendering performance of the stadium lights, the clearer and more realistic the color of the objects and spheres, and the closer to the lighting quality and effect of sunlight.

The lighting design experience of high-end sports venues has shown that under the conditions of horizontal illumination and vertical illumination, the sports lights with high color rendering performance are used, and the field lights constructed by matrix uniform lighting are used. The brightness, clarity, authenticity and comfort of the venue's lighting are much higher than the lighting quality and lighting effects of low-color performance venue lights.

Photophysical element 3: 

The site lighting should be smooth and stable without fluctuations and no stroboscopic effect hazard. The phenomenon of sports lighting fluctuations is called stroboscopic. The stroboscopic energy of the stadium lighting acts on the human eye and can cause stroboscopic effects in the visual perception system. Lead to visual positioning is not accurate, or create visual illusion and cause visual fatigue.

Photophysical element 4:

The lighting of the venue should not be dazzling, and anti-glare is important. The glare hazard of the stadium lighting is the visual discomfort generated by the stadium lighting in the human eye. It is characterized by glare hazard in the form of dimly lit, glaring, dazzling, etc.

Once the lighting of the venue is glared, the players will often see a bright and dazzling light curtain in multiple locations and multiple angles, and they will not see the sphere flying in the air. The greater the glare energy of sports venue lighting and sports lighting, the more serious the damage of the venue lighting glare.

The glare hazard of the stadium lighting is an important factor affecting the quality of the stadium lighting. There are already many lighting projects for folk sports venues. The projects cannot be delivered and has to be redesigned Because of the serious dazzling of the light. Therefore, it can be seen that the glare hazard effect of the venue lighting is a technical factor that should be taken seriously when the stadium lighting design.

The conclusion:

In the sports hall lighting project, the photophysical elements of the four aspects of the stadium lighting are the key factors for building an excellent venue light environment. In the actual venue lighting design and lighting project, the four elements should be available at the same time. The lack of any one will seriously affect the integrity of the lighting environment of the venue and the quality of the lighting.
