Something of stadium lighting design and selection needs to know

In indoor table tennis, badminton, basketball, volleyball and tennis venues, or outdoor sports fields, maybe you can see many different high power sport lights such as 1500w led flood light, 500W modular floodlights etc. the design of stadium floodlights should consider the horizontal and vertical illumination of the venue, and the light and color quality of the sports lighting. Only by comprehensively considering the specific details of these two aspects and adopting a scientific and reasonable lighting (light) mode can the venue lighting be of high quality.

Indoor venue lighting design key considerations: stroboscopic effect hazards

There are four main aspects of the light and color quality of sports lighting for civil indoor badminton, table tennis, basketball, volleyball, tennis and other venues, which should be seriously considered when designing stadium lighting.

First, the venue lighting is not dazzling, not dazzling, not dazzling, not dazzling, and there is no glare hazard effect.

Second, the stadium floodlights do not fluctuate, but is smooth and stable. No stroboscopic energy and stroboscopic effect hazards.

The third is, sports lighting, the color of sunlight, pure white and bright, just like daytime.

Fourth, the venue lighting has a high light color rendering index, strong color rendering ability, and pure and true colors.

Among the four indicators, as long as the sports lighting has a large stroboscopic and stroboscopic energy, the stadium lighting will have a stroboscopic hazard effect and reduce the quality of the stadium lighting. However, the stroboscopic hazard effect is not very obvious under ordinary visual conditions. Therefore, it has a certain degree of concealment.

The stroboscopic effect hazard performance can only be clearly manifested under certain conditions. This specific condition is that the angular velocity of the sphere in the air and the flight speed resonate with the stroboscopic frequency. And, it is manifested in a specific form.

Because of this, the stroboscopic hazard effect has a certain concealment. For many years, when designing and selecting sports lighting for sports venues, many people did not pay enough attention to the stroboscopic energy and harm of stadium lights, or even ignored them.

In fact, the stroboscopic energy of stadium lighting is an important light factor that affects the quality of stadium lighting. The stroboscopic effect of stadium lighting will seriously affect the lighting quality and effect of stadiums. The stroboscopic hazard effect is a phenomenon that should not exist in stadium lighting.

Only the sports lighting has no stroboscopic energy, the sports venue lighting can be smooth and stable, not fluctuating, and there is no stroboscopic effect. Only the flight trajectory of the sphere can be real, and the aerial positioning can be accurate. See and hit the spheres in the air accurately.

Once the stadium lighting, the generated stroboscopic energy is relatively large, there will be a stroboscopic hazard effect. The greater the stroboscopic energy of sports lights, the greater the stroboscopic hazard effect. Balls such as table tennis and badminton flying in the air, the trajectory will be more unreal. When the ball is inaccurate, the positioning is inaccurate, and the ball is inaccurate, the more serious the phenomenon is. So when you choose floodlight manufacturer for these lights, you should ask them to pay more attention on this.

Manifestation of stroboscopic hazards of lighting in indoor sports venues

Sports light strobe is a physical phenomenon that indicates that light is fluctuating. Wave light is a kind of energy, which has characteristic parameters of wave frequency and wave amplitude. Frequency characterizes how fast or slow light fluctuates. Amplitude characterizes the amount of stroboscopic energy.

The stroboscopic energy acts on the photoreceptor cells of the human eye, and in the visual perception system, it has a harmful effect on the clarity and authenticity of the visual image and the visual comfort, that is, the stroboscopic effect.

The stroboscopic effect of stadium lighting is mainly manifested in two aspects in stadium lighting

One aspect: it causes visual nerve fatigue and visual discomfort. In severe cases, it can lead to migraine headaches and nausea. This harmful effect will definitely occur as long as the stadium lights have a relatively large stroboscopic energy. And as time goes on, the discomfort will accumulate and worsen. Quietly, it impairs the physical and mental pleasure of sports players unknowingly.

On the other hand: whenever the stroboscopic frequency is in resonance with the speed of the sphere’s flight and spin. Badminton, table tennis and other spheres flying in the air, the flight trajectory will appear sphere string phenomenon. Instead of a sphere flying in the air, the visual image appears to be behind the first sphere, followed by several spheres. As a result, the flying trajectory of the sphere in the air is unreal and the positioning in the air is inaccurate. The ball can’t be seen and can’t be played.

Countermeasures to Eliminate the Harmful Effect of Lighting Strobe in Indoor Sports Venues


  1. If there is no stroboscopic hazard effect in the lighting of sports venues, it is necessary to choose sports lighting without stroboscopic energy and stroboscopic effect hazards or choose the solar powered floodlights.


  1. In order for sports lights to have no stroboscopic energy and stroboscopic effect hazards, the electric power that drives the stadium lights to emit light is either direct current energy or alternating high frequency electric energy. For AC high frequency, theoretical analysis and practical test show that: only when the frequency of high-frequency electric field energy is greater than 40 kilocycles (Khz), the stroboscopic energy of the venue lighting can be very small, and the venue lighting can be free from the stroboscopic effect.


  1. Any driving electric power frequency lower than 40 thousand cycles (Khz) will definitely produce stroboscopic energy and stroboscopic effect hazards. The lower the frequency, the more serious the harm of stroboscopic energy and stroboscopic effect. The 50-cycle (hz) power-frequency AC-driven sports lights have the largest stroboscopic energy and the most serious stroboscopic effect.
