Requirements For Sports Lighting Application Technology

We are all familiar with the gymnasium, which is the main place for us to exercise and keep fit. For the stadiums and gymnasiums, lighting is indispensable part. In fact, not only the stadiums, but also our life or production cannot do without the outstanding contribution of lighting. Compared with civil lighting and industrial lighting, sports lighting is more professional, which has higher requirements for its application technology.

And these requirements can be showed in the following points.

The color drift of LED in the stadiums.

In the color performance indicators of LED products, color rendering index (CRI), color temperature(Tcp), color tolerance of the light source and color deviation can be quantitatively specified. But due to the effect of different factors in practice, as time goes on, the on-site color rendering index (Ra) will increase and the color temperature (Tcp) will decrease, which makes a big difference between the initial value. Compared with traditional metal halide lamps, the color temperature and color rendering index of LED lighting fixtures have the certain advantages and guarantees.

The glare of LED lighting fixtures.

The glare in the stadiums not only affects the competition, but also affect the athletes' mood. If the emitted light directly irradiates on the camera lens, it will also produce camera glare and affect the shooting. In addition to preventing the glare caused by LED lighting, installation height and projection angle of lamps are also important factors in controlling the glare.

To solve the problem of the glare, OAK LED lighting fixtures are tailored to the different features of sports stadiums and have the advantages of high luminous efficiency, high uniformity, high performance, anti-glare, low flicker, no light pollution, and so on.

The stroboscopic effect of LED lighting fixtures.

There are two indicators for evaluating the stroboscopic effect: stroboscopic ratio and stroboscopic index. In practice, the stroboscopic is especially important for stadium lighting. The broadcast picture is prone to jitter when the broadcast game needs slow motion or super slow motion playback. Therefore, many sports competitions have put forward requirements for sports TV broadcast strobe, and some gymnasiums have set the strobe ratio to less than 3%.

To solve the problem of stroboscopic, OAK LED lighting fixtures achieves the lowest flicker rate less than 0.2%, which will not cause the eye fatigue and protect the eye health.
