It’s annoying to miss a goal due to flickering lights in the football filed, but do you know why the LED lights used in the stadium flicker? LED lights have been used extensively in sports since ancient times, but the flickering problem has always existed, the switch and glowing technology is usually the main cause of flickering. This article describes an LED device that addresses the flickering problem of stadium lighting.
The type of LED Flickering
LED stadium lighting flickering can be divided into two categories based on wavelength, one is visible to the naked eye and the other is invisible. Visible flickering is the rapid conversion of LED stadium light waves, visible light changes in frequency up to 40 Hz. For the naked eye invisible flickering is difficult to be detected, but long-term in such an environment will also produce discomfort.
The reason why LED lights Flickering
First, poor quality bulbs and lamps tend to flicker. Individual LED stadium flood lights are small, but through the combination of various component systems, cheap components are often unreliable and fragile, ultimately leading to flickering. Of course, price is not the only factor that measures product quality. Choose a reliable quality supplier to significantly reduce maintenance costs later.
Second, loose switches or loose connections are another common cause of flickering and should be rechecked and the switch tightened.
Third, the LEDs used in sports are usually controlled by the voltage of the driver. If the driver is damaged, the change in voltage of the AC current will cause the LED stadium lights to flicker. So a high quality driver can reduce/avoid flickering.
Fourth, the LED lights used in sports are high-power, 1000W to 2000W, and connecting multiple high-power LED lights will increase the current surge when the driver is damaged, indirectly affecting flickering.
Is Flickering harmful to our health?
Modern medical research has shown that both visible/invisible flickering are harmful to human health. If you work in an invisible flickering environment for a long time, you are likely to suffer from dizziness and headaches, and the exhilaration of watching a sports game may exacerbate such symptoms. Visible flicker has been shown to have a direct relationship with photosensitive epilepsy seizures in addition to visual effects.
How to solve the Flickering in stadium？
Flicker solutions are primarily based on quality LED equipment and regular maintenance checks. A high-quality matrix LED device reduces the possibility of LED flickering, facilitates maintenance after maintenance, and extends service life. Regular inspection, maintenance and replacement of LED lighting is an important way to reduce flicker in scenes with high lighting demands such as football stadiums.
