Sports Lighting and Introduction
Factors Affecting Gymnasium Lighting
2. Illumination uniformity. Taking basketball competition venues as an example, the middle venue often gathers more light, but areas with excessive lighting often produce dim light, while areas with high lighting often have weak lighting brightness, ensuring the overall lighting uniformity of the venue. This plays a crucial role in the athletes' level of performance.
3. Glare. In the regulated party system, there are uncomfortable visual effects such as dazzling, dazzling, and dazzling. Fan Guang has a significant impact on athletes, such as their inability to accurately determine the landing point of the ball. In order to ensure uniform illumination at all angles and prevent indoor lighting, the angle from the low point of the projection point of the gymnasium to the lighting fixtures must be greater than 45 °. Nowadays, many sports enthusiasts use computers to calculate projection points to ensure the uniformity and distribution of light.
4. Light source specialist. In simple terms, it refers to the authenticity of the color of the object, and a light source with bright color rendering can better reproduce the color of the object, which is closer to the natural primary color.
5. Illumination requirements. When the horizontal illumination and vertical illumination of the sports field are equal, the visual effect is the most comfortable. Even if equal, the horizontal illumination cannot exceed twice the vertical illumination.
2, Light Source and Lamp Selection
1. Light source selection
Common sports enthusiasts can be divided into two categories, one requiring a larger spatial range. For example, basketball, volleyball, table tennis, etc., while another fan is a low altitude fan group activity competition, which includes fencing, water skiing, palm hitting, wrestling, and softness. To avoid the impact of glare on athletes, it is necessary to strictly control the light level 1 and add a unified baffle for various monitoring purposes.
2. Selection of lighting fixtures for sports venues
The lighting source of the stadium town is white R light, Zhiguang light, all halide light, and high-voltage trees. Nowadays, sports lighting requires high spatial color and color temperature, in order to meet the needs of the operation of Qingni TV. At the same time, the light source should maintain a sufficient lighting intensity under the premise of the scenery. After years of research and practice, LED stadium lights are currently widely used as sports lighting sources internationally.
Three Lighting Control and Lighting Layout Plan 1
1. Light control
There should be a lighting control room inside the gymnasium, where the lighting conditions of the venue can be observed. Nowadays, many sports use computer intelligent lighting control, and staff can easily control the lighting. Different lighting requirements can be met according to the control lighting circuit scheme.
2. Lighting layout scheme
Dongfang Anzhong has conducted a detailed analysis of the site plan and conducted computer analysis and calculation. Through reasonable layout of ambient lights and different lighting modes, it has achieved the requirements of different levels of lighting and commercial activity illumination.
The mouth has entered the rapidly growing Huang Quanming era. In the future, only by continuously innovating ED lighting technology and closely cooperating with LED's upstream and downstream reinforcement equipment and accessories, can we meet the demand for information technology and venue management in Puzu Games and win the favor of the market.
Reference standard for lighting design of sports venues
Previously, we discussed the importance and role of lighting design in sports venues. So, how to fully utilize the role of sports venue lighting design, we need to understand specific reference standards and requirements for sports venue lighting design. Including illumination, color temperature, color rendering, glare control, etc., all need to be carefully considered and implemented in place.
1, Illumination requirements
Taking football stadiums as an example, according to the recommended illuminance for sports venues in the International Sports Federation Document No. 83 and the provisions of the "Lighting Design Standards for Civil Buildings" GBJ133-90, we need to meet the following requirements for the illuminance level of football stadiums:
Lighting design of sports venues
1. Taking the lighting design of football fields as an example, according to Article 2.2.9-1 of the "Lighting Design Standard for Civil Buildings" GBJ133-90, the standard value of lighting for football field matches is: when the viewing distance is 120m, the lighting should reach 150-200-300lx; When the viewing distance is 160m, the illumination should reach 200-300-500lx; When the viewing distance is 200m, the illumination value is required to be 300-500-750lx. Viewing distance refers to the distance from the last row of the audience to the sideline of the venue.
2. The live broadcast of sports programs also needs to consider the vertical illumination of television broadcasting. According to Article 2.2.9-2 of the "Lighting Design Standard for Civil Buildings" GBJ133-90, the vertical illumination required for television broadcasting is divided into three groups: the maximum shooting distance:
a. For football projects, when the maximum shooting distance is 25m, the average vertical illumination should reach 750lx;
b. When the maximum shooting distance is 75m, the average vertical illumination is required to reach 1000lx;
c. When the maximum shooting distance is 150m, the average vertical illumination is required to reach a level of 1500lx.
Among them, due to the fact that many sports venues share the same venue for football and track and field events, additional requirements are required for track and field events: when the maximum shooting distance is 25m, the average vertical illumination is required to reach 500lx; When the maximum shooting distance is 75m, the average vertical illumination is required to reach 750lx; When the maximum shooting distance is 150m, the average vertical illumination value is required to reach 1000lx.
Note: The vertical illuminance requirements mentioned above are applicable to a specific given level of motion and the minimum shooting distance relative to a 1.0m vertical plane, while the middle value of each illuminance value is applicable to other shooting distances.
3. The above illuminance refers to the final average illuminance of the sports stadium. When designing lighting, we need to add an additional maintenance coefficient, usually using a coefficient value between 0.7 and 0.8.
4. Uniformity of horizontal illumination: The uniformity of illumination is generally expressed as the ratio of minimum to maximum illumination, or as the ratio of minimum to average illumination. The ratio of minimum to maximum illumination should be greater than 0.5. In addition, we also need to pay attention to the vertical illumination uniformity of the venue: the ratio of minimum illumination to maximum illumination should be greater than 0.4 to meet the requirements of the main television camera.
Lighting design of sports venues
2, In terms of lighting quality
1. Glare control
Due to the large space of sports venues and the large number of participating groups, including athletes and referees, as well as spectators, venue management, etc., when designing lighting for sports venues, it is necessary to pay attention to the control of glare in each space. This not only achieves good lighting effects, but also allows athletes to better showcase their competitive skills, while also allowing the audience to fully see the details of the competition.
According to CIE Publication No. 83 "Sports Ground Lighting for Color TV Systems", the maximum glare index GRmax inside the venue should be less than 50. The smaller the glare rating GR, the better the glare control, when the glare rating is 50. The glare rating GR can be calculated using the following formula:
GR=27+24Lg, Lvl/Lve 0.9. In the formula, Lvl is the brightness of the light curtain generated by the lamp, and Lve is the brightness of the light curtain generated by the environment. The two should be treated separately. When calculating venue illumination, we should remember to take into account the glare values in different directions. Only when the rated value GR<50, can the overall plan still operate.
Of course, there are many ways to limit glare, such as selecting a reasonable type of lighting fixture, adjusting the installation height, angle, and arrangement of lighting fixtures, and also using methods to brighten the background of the competition to "reduce" glare.
2. Standard for color temperature and color rendering of light sources
In order to achieve better viewing and television broadcasting effects, the lighting quality of sports venues is not only related to illumination, but also to color temperature and color rendering. If the illumination meets the standard, it can only make us "see clearly", while if the color temperature and color rendering meet the standard, it can make us "see well".
According to Article 3.3.2 of China's "Lighting Design Standard for Civil Buildings" GBJ133-90, for general light sources used for color television broadcasting, their color rendering index Ra should not be less than 65. In addition, according to CIE Publication No. 83 and FI-FA requirements, the color temperature Tc of the light source is greater than 5000K and the color rendering index is greater than or equal to 80. That is to say, in the lighting design of sports venues, the color temperature of the light source should be higher than 5000K, and the color temperature should at least reach Ra>65.
Lighting design of sports venues
3. Directionality of light
As mentioned earlier, the control of glare is closely related to the directionality of the lighting fixtures. But at the same time, the depression angle of the lamp can also change the vertical illumination. Therefore, when designing stadium lighting, it is necessary to control the direction of illumination of the lighting fixtures. In addition, the ratio of the main camera to the light coming from the other side should be controlled within a certain range, and the key lighting area is still the center of the court.
4. Overall, we need to achieve energy conservation and environmental protection
The lighting electricity for sports venues belongs to commercial electricity, and the electricity consumption of the entire venue is very high, and the daily electricity bill may sometimes be several thousand yuan. Therefore, energy-saving issues must be considered in the lighting design of sports venues.
For energy conservation, what lighting design companies can do is to develop reasonable lighting plans, choose efficient lighting fixtures, reduce line losses, and design good lighting control systems.
When choosing lighting fixtures for universities, we should set up reasonable and diverse switch modes and corresponding control schemes to flexibly adjust for different sports events.
