Specifications of outdoor basketball court lighting design are as follows: 1, the general basketball court tube, directly from the distribution box out of several lighting circuits, each loop in series no more than 20 lamps, the control circuit breaker direct control. 2. In the basketball court with a higher grade, an intelligent time controller is set inside the distribution box, and the lighting on time is set according to the needs of the owner.
Lighting part: The light part should first look for the specification “architectural lighting design standard” GB 50034-2004, according to the requirements for indoor basketball court illumination and glare, and the requirements for the value of the lighting power density, and then use the conditions to reverse the use of The power of lamps and the installation of lighting fixtures are actually more of a look at books on lighting design.
Specifications of outdoor basketball court lighting design : You can refer to the football stadium’s lighting design, quadrangular or two-sided design, focusing on “no shadow”, “glare” problems, of course, there is a very important to meet the lighting illumination under the premise.
Outdoor lighting design mainly has three steps:
1 According to the light distribution and illumination requirements of the site, determine the installation location of the lamp; whether the high width is consistent;
2 Perform the necessary light calculations to determine the number and power of the lamps;
3 Use “point by point calculation method” (see lighting calculation) to determine the illumination angle of the used lamps (such as floodlights) and set the required illuminance value. For design convenience, the illuminance of outdoor lighting is generally based on the horizontal (face) illuminance. However, in many situations, it is required to see the targets on the vertical plane (such as golf and archery).
Therefore, it is necessary to understand the ratio of the horizontal (plane) illumination and the vertical (plane) illumination produced by various lighting systems. Under normal circumstances, if the angle between the incident light and the horizontal normal line is less than 45, the ratio of the vertical (plane) illuminance to the horizontal (plane) illuminance is smaller, such as greater than 45, then the vertical (plane) illuminance and level (face ) The proportion of illuminance is greater. When the installation height of the lamp is low or the illumination angle of the lamp is increased, although the vertical illuminance can be increased, glare can be generated at the same time.
