hockey lighting

Professional sports, a multi-purpose situation is very common, for example, indoor sports venues can be used both as a basketball game and as a hockey game, but the requirements for basketball lighting and hockey lighting are different. This poses a problem for the stadium. How do you meet hockey lighting while meeting basketball court lighting?

Stadiums can create richer and more engaging atmospheres by changing the color of the facility lighting. This practice is called color temperature adjustment. While using red, blue or green light to illuminate the floor (also known as RGB adjustment), indoor sports venues often use more subtle applications to illuminate the venue with white light to best show the game. Changing the color of white light in space is called whitening balance.

White light exists in many different shades and is measured in K. The lower the K value, the warmer and yellower the white light tone is. A higher color temperature indicates that the white light has a cooler, bluish hue. It is generally considered that 5600K is the daylight color temperature at noon.

For a multi-purpose stadium, the color temperature of white light is an important consideration because different sports look better under different white lights. The wood tones of the basketball court and the exposed skin of the players are more active under warm white lighting (around 4000K). However, under the 4000K light, the hockey ice cubes are dull and dirty, but when illuminated with 5600K lights, the hockey ice cubes appear crisp and clean.

Then, for a stadium that undertakes multiple activities, using a single lighting system to achieve multi-color white light is a challenge.

Most light sources and luminaires emit a white light under the target illumination. In the past, two different lighting systems were needed to illuminate the arena, creating optimal conditions for basketball lighting and hockey lighting while maintaining the lighting level of the playing field.

The two lighting systems need to be coordinated to get the desired color of light on the court. For hockey lighting, only 5000K metal halide can be used to illuminate the ice, producing the coolest color temperature the system can provide, but still not achieving the best 5600K. In order to improve the color temperature of the basketball game, the mix of 5000K and 2700K lamps will produce an illumination color temperature on the court, falling somewhere within the range. This inaccurate and imperfect dual system approach has long been the only option for the arena to achieve white balance.

New LED stadium lighting

Advances in LED materials, design and control have enabled LED luminaires to emit white light in different shades. These toned LED sports lighting fixtures combine two LEDs of different color temperatures (3500K and 6500K) and then adjust the power into the different color diodes to produce an accurate color temperature.

The multi-purpose arena can now be hockeyly illuminated in a 5600K environment, basketball lighting in a 4000K environment, and optimal lighting levels at the venue. Hockey stadium lighting can be achieved with the Razorlux LED sports lighting system.
