Sports venues are divided into stadiums and gymnasiums, stadiums generally refer to outdoor sports venues, stadiums generally refer to indoor sports venues, said the difference between stadiums and gymnasiums, the first reaction of many people is that one is outdoor, by the wind and rain in the sun, one is indoor, can shelter from wind and rain, but also can prevent the sun, enjoy air conditioning, of course, the natural wind of the stadium is also good. In fact, there are also differences between stadiums and gymnasiums in sports lighting.
The stadium rarely uses artificial lighting during the day, basically using natural light is enough. However, in cloudy days, there may be insufficient light, and artificial lighting is needed to fill the light, at this time, you need to consider energy saving, how many lights to open, and how many lights to open, which is a test of technology. At dusk, in order to better match the stadium lights with daylight, the color temperature of the stadium lighting source is generally required to be 4000K or slightly higher.
Stadium lighting can be divided into two kinds, one is the use of natural light, the other is the basic isolation of natural light. The use of natural light of the gymnasium, in the sports center is more common, this kind of stadium is generally relatively tall, wide, more Windows, or the ceiling is translucent, natural light is easier to come in, but also to prevent direct sunlight, affecting sports. During the day, general training and competitions or recreational and sports activities can be done without opening stadium lamps. Professional competition, only need to open a part of the lamp can.
Basically do not use the natural light of the gymnasium, the more common is the external operation of the badminton hall, the window of these badminton halls is relatively low, there is little natural light, there is no natural light in the high air, so even if the sun is fierce during the day, these badminton halls should also turn on the light.
The stadium lighting requirements will basically be higher than the stadium lighting requirements, if there is a TV broadcast site average horizontal illuminance and average vertical illuminance ratio should be: stadium 0.75~1.80, stadium 1.0~2.0. For example, if the glare level is 4, the stadium glare index (GR) is between 35 and 40, and the stadium glare index (GR) is between 60 and 70.
Sports lighting in addition to the glare value, color rendering index, color temperature, strobe and other requirements, the control of the lamps also have corresponding requirements, based on the basic requirements of energy saving, venues need to be able to flexibly control the method of lighting, according to demand distribution of stadium lighting.
Stadium lighting requirements In addition to the sports field, the audience lighting and emergency lighting are also required. The purpose of audience lighting is not only to meet the need to see the seats in general, but more importantly to meet the requirements of television transmission camera, including close-up and slow-motion replay of some important officials and famous figures. Among them, the average vertical illumination of the front 12 rows of the auditorium and the rostrum facing the field direction shall not be less than 10% of the average vertical illumination of the landlord’s camera direction in the arena. The average level illumination value of the podium should not be less than 200lx, and the minimum level illumination value of the audience should not be less than 50lx.
Sports venues are often characterized by large building volume, can accommodate thousands or even tens of thousands of people, large density of people, to ensure the safety of a large number of people in the stadium is extremely important, especially in the event of an emergency, should the stadium emergency lighting is more essential.
