design of the stadium lighting

Currently, badminton, table tennis, basketball, volleyball, etc., indoor sports venue lighting . Frequently used stadium lights, there are metal halide lamps, T5 energy-saving lamps, ordinary high-power energy-saving lamps, LED high-power energy-saving lamps, high-frequency electrodeless lamps, 6U-60W high-frequency energy-saving lamps. Among them, metal halide lamps, T5 energy-saving lamps, ordinary high-power energy-saving lamps, these three kinds of sports lighting, have different degrees of stroboscopic and stroboscopic effects.

In order to facilitate the design of the stadium lighting , the stroboscopic energy status and the stroboscopic hazard degree of the six site lights are briefly compared as follows.

(1) 400W metal halide lamp. It belongs to gas discharge and light stadium lights, and most of them use inductive ballasts to ignite. Qihui ignition is to directly load 50Hz power frequency AC power on the illuminant and directly drive its illuminating.

The 400W metal halide lamp is excited by an electric field, and the metal atom is excited to emit characteristic line light. Because of this, the light energy of the 400W metal halide lamp is sinusoidal fluctuation with the frequency of the industrial frequency alternating current at 100Hz. Moreover, the fluctuation range is large. The lighting practice of the stadium has proved that the stroboscopic energy of the 400W metal halide lamp is the largest, and the stroboscopic effect is also the biggest.

(2) T5 stadium row lights and U-shaped spiral type high-power energy-saving lamps. Both types of sports lights are field lights that are driven by electronic ballasts and gas discharge photoluminescence. Whether there is stroboscopic energy and stroboscopic effect hazard depends on the AC (AC)-DC (AC)-AC (AC) switching frequency of its matched electronic ballast.

When the conversion frequency of the electronic ballast is lower than 40 thousand cycles (Khz), the stroboscopic amplitude is relatively large, and the stroboscopic energy is relatively large. Venue lighting will definitely have a stroboscopic hazard effect. The lower the conversion frequency, the greater the stroboscopic energy and the more serious the stroboscopic hazard.

Currently, T5 stadium lights and U-shaped spiral high-power energy-saving lamps are being sold and used. The switching frequency of its electronic ballasts is mostly below 40 thousand cycles (Khz). The majority in the 20 thousand weeks (Khz), and a few are only between 10-20 weeks (Khz). The stroboscopic energy and stroboscopic effects are relatively harmful. It is recommended to consider carefully when choosing.

(C), LED high-power energy-saving lamps. It is a sports light that excites electroluminescence with a DC electric field. The DC electric field is smooth and stable, and the LED high-power energy-saving lighting energy is also smooth and stable. Therefore, LED high-power energy-saving lamps have no stroboscopic energy and stroboscopic effects.

(4)  High frequency electrodeless lamps. It is a magnetic field that excites a photoluminescent field lamp that excites the magnetic field at frequencies up to the megahertz level. The luminous flux emitted by the high-frequency electrodeless lamp is smooth and stable, and does not fluctuate. No stroboscopic and stroboscopic effects.

(5)  6U-60W high frequency energy saving lamp. It is a special stadium light for sports lighting developed by Qingdao Frank Microelectronics. It is also an electric field excitation, gas discharge photoluminescent field lamp.

The 6U-60W high-frequency energy-saving lamp uses high-frequency energy-saving fluorescent tubes and is equipped with high-frequency electronic ballasts to drive illumination. Matched high frequency electronic driver (electronic ballast) with AC (AC)-DC (DC)-AC (AC) switching frequency up to 45 thousand cycles (Khz). 6U-60W no glare harms high-frequency energy-saving lamps, the stadium lights are smooth and stable, no fluctuations, no stroboscopic energy. In the stadium lighting, there is no stroboscopic hazard effect.
