Hockey field lighting design principles: the lighting quality mainly depends on the level of illumination, uniformity and glare control.
It should be taken into account that its output illuminance is reduced due to dust or light attenuation. Light attenuation depends on the installation location of the ambient conditions and the type of light source selected, so the initial illuminance is preferably 1.2 to 1.5 times the recommended light.
LIGHTING REQUIREMENTS
Lighting standards for hockey field are as below.
Level | Fuctions | Luminance(lux) | Uniformity of Illuminance | Light Source | Glare Index (GR) |

INSTALLATION RECOMMENDATION
Glare depends on light density, projection direction, quantity, viewing position and ambient brightness. In fact, the quantity of lights is related to the quantity of auditoriums.
Relatively speaking, a simple installation of the training ground is enough. However, for large stadiums, it is necessary to install more lights by controlling the beam to achieve high brightness and low glare. Glare not only affects athletes and spectators, but can also exist outside the stadium. However, do not cast light into the surrounding roads or communities.
