Usually, indoor lighting of stadiums mainly USES LED projection lights (main outside), LED downlights and mining lights (main inside). However, there is little understanding of the factors such as light balance and insufficient illumination in local areas.
These, however, actually affect the lighting professionalism of a stadium!

Projection lamp applications
-- White dimming challenge for semi-indoor areas
Sports venues create a more attractive atmosphere by changing the color of the lighting fixtures. This practice is called color temperature regulation.
For multi-purpose indoor venues, the color temperature of white light is an important consideration because different sports look better in different white light. The wood tone of the basketball court and the players' exposed skin are more active under the warm white-toned lighting (around 4000K). However, hockey ice is dull and dirty under 4, 000 k of light, but crisp and clean under 5, 600 k of light.
So, for stadiums hosting multiple events, using a single lighting system to achieve multiple colors of white light is a real challenge.
Luminaire application:
With advances in LED materials, design and control, LED lamps represented by LED projection lamps can emit white light of different hues. These color-modulated LED motion lighting fixtures combine two LED light sources with different color temperatures (3500K and 6500K) inside, and then adjust the power going into the different color diodes to produce a more accurate color temperature. In this way, multi-function venues can simultaneously maintain an ideal color temperature level in the competition area.
