Hockey is one of the oldest and glorious events in the Olympic Games. Modern hockey sports originated in England in the early 19th century. Men's and women's hockey were then listed as Olympic events in 1908 and 1980 respectively.  The hockey field is 91.40m long and 55m wide. The goal is 2.14m high and 3.66m wide. The stick is 80~90cm long and the ball weighs 156~163 grams.
Hockey stadium lighting can be divided into the following four levels according to the basic requirements:
1. No sports games.
2. Training and lower-level club competitions.
3. High-level clubs and international competitions.
4. Color TV broadcast
Recommended minimum illumination for hockey fields :
Lighting type | Ehinit | Ehmaint | Evinit | Evmaint |
Non-sports games | 250 | 200 | _ | _ |
Training and lower-level club competitions. | 375 | 300 | _ | _ |
High-level clubs and international competitions. | 625 | 500 | _ | _ |
CTV≥75m | _ | _ | 1250 | 1000 |
CTV≥150m | _ | _ | 1700 | 1400 |
Widescreen TV | _ | _ | 2500 | 2000 |
2.Non-flickerThe lighting level of the auditorium: In order to ensure the safe entry and exit of the audience, the minimum average level of illuminance in the auditorium should be 10% of the average level of illuminance in the moving field, if it reaches a comfortable level. The minimum average level of illuminance in the auditorium is best for the sports field 20% of the average horizontal illuminance.
The stroboscopic effect is the phenomenon that the movement of an object is observed to be different from its actual movement under the irradiation of light with a certain frequency change, and the usual manifestations are jitter , flashing, etc. The stroboscopic effect has a great impact on TV broadcasting. It is conceivable that if the TV screen appears jittery, flickering, etc., TV audiences will not be able to accept it, and the economy of TV broadcasting such as TV advertisements and TV broadcasting rights will be greatly affected. Especially now that we have entered the LED lighting era, the stroboscopic effect is more prominent, which greatly affects the effect of broadcasting, especially for high-definition TV broadcasting and slow motion.
The uniformity of illumination on the horizontal and vertical planes is a very important parameter. A good uniformity can not only avoid uncomfortable adaptation problems for athletes and spectators (uncomfortable adaptation can easily cause visual fatigue), but also avoid cameras in different directions Adjustment problem. If the uniformity is not good, in certain positions on the field. You cannot see the ball and the players clearly. The illuminance gradient on the site should not change too much. The recommended illuminance gradient is 25% d5m. The uniformity of illuminance is generally expressed by the ratio of the minimum illuminance to the maximum illuminance, and can also be expressed by the ratio of the minimum illuminance to the average illuminance.
Lighting type | Horizontal uniformity | Vertical uniformity | ||
| U1 | U2 | U1 | U2 |
Non-sports games | 0.5 | 0.7 | _ | _ |
Training and lower-level club competitions. | 0.5 | 0.7 | _ | _ |
High-level clubs and international competitions. | 0.5 | 0.7 | _ | _ |
CTV≥75m | 0.5 | 0.7 | 0.4 | 0.6 |
CTV≥150m | 0.5 | 0.7 | 0.4 | 0.6 |
Widescreen TV | 0.7 | 0.8 | 0.6 | 0.7 |
U1=Emin / Emax ; U2=Emin / Eaverage
The color rendering and color temperature of the light source are related to comfort and the emotions of athletes and audiences, especially the needs of color TV broadcasting. The following table is the minimum color rendering index and color temperature recommended for hockey stadiums. The data in parentheses are the recommended best to achieve value
Lighting type | CRI Ra(Min) | CCT TK |
Non-sports games | 20 | 2000 |
Training and lower-level club competitions. | 65 | 4000 |
High-level clubs and international competitions. | 65 | 4000 |
CTV≥75m | 65(90) | 4000/5000 |
CTV≥150m | 65(90) | 4000/5000 |
Widescreen TV | 90 | 5000 |
Nowadays, hockey stadium lighting is increasingly pursuing high brightness but ignoring an important issue, that is light pollution. Light pollution has a great impact on the surrounding residents and affects people’s normal lives. In addition, light pollution will also have an impact on surrounding organisms, so lighting designers should not ignore this issue when performing hockey stadium lighting.
The problem of glare caused by lighting has always been complained by players and spectators. A good hockey lighting requires that the field lighting should not cause glare to players, referees, staff and spectators.
The smaller the glare rating (GR), the better the glare limit. When the glare rating is 50, it is just acceptable. Generally, when calculating the illuminance, the glare rating (GR) in different directions should be calculated. When GR<50, it is considered feasible.
The color temperature of the light source : Because the game generally lasts from afternoon to dusk, the color temperature of natural light is between 4000K-6000K. In order for the TV camera to work continuously and normally and from natural light to artificial lighting, there will be no obvious color difference changes. Therefore, the color temperature of the lighting source must be 4000K. Between 6000K, in the same field, the color temperature can not deviate from the average value by more than 500K.
The color rendering of the light source : The color rendering of the light source is specified in the above table. Generally, the color rendering index of the light source can reach 80 or even more than 90, which has a better effect on ensuring the TV camera.
The uniformity of illuminance refers to the ratio of the minimum illuminance to the average illuminance on the specified surface. The more uniform the light distribution, the better the illuminance and the more comfortable the visual experience. The closer the illuminance uniformity is to 1, the better; on the contrary, the smaller it is, the more visual fatigue will be increased.
Since the hockey field is open-air, the hockey field lighting not only requires good corrosion resistance and waterproof performance, but also requires it to have a long lifespan.If the lifespan is not long, it will increase the user's cost.The theoretical service life of a good hockey stadium lighting should be no less than 30 years.
The high luminous efficiency of LED lighting cannot be achieved by traditional lighting. The luminous efficiency of LED lighting on the market is generally 130lm/w—140lm/w, while the luminous efficiency of our hockey stadium lighting can reach 170lm/w, which is in the market Is rare. Such high light efficiency can save users a lot of electricity bills and can reduce the cost for users by 42%, but the brightness is even brighter.
LED lighting far exceeds traditional HID fixtures in terms of lifespan, because LED lighting works relatively smoothly and will not be easily burnt. This long lifespan can save customers unnecessary costs, and it is easier to maintain. Longer durability is reflected in strong corrosion resistance and a high waterproof level.
Nowadays, the installation of LED lamps is no longer as cumbersome as traditional lighting, it is more convenient to install, and the installation methods are also various and optional. Our hockey stadium lighting can provide users with three mounting brackets to meet all the installation needs of customers, and it does not take a lot of time to install, and the installation is quick and easy.
4.Professional lighting layout design
4.1 Lamp with cloth lamp
For international competition levels, when the auditorium has a higher canopy, the lamps should be installed on the outer edge of the canopy. The frame for installing the lamps should be integrated with the scaffolding structure of the hockey field, and there should be dedicated maintenance channels. It can also be installed on the light poles on both sides of the sideline (8-pole lighting method), but it should be noted that the light poles should not affect the sight of the audience, and should meet the following requirements : ɑ > 25°.
4.2 Light pole cloth lamp
For non-sports competitions and training and low-level club competitions, 6 or 8 light poles can be installed on both sides of the sideline of the venue. For non-sports competitions, the height of the light poles can be 15m. For training and low-level club competitions, the height of the light pole is at least 18m. In order to prevent glare, the figure should satisfy ɑ > 25°, which is determined by the position of the pole and the angle a. You can also determine the appropriate height of the pole.
4.3 Four-corner cloth lamp
For the international competition level, when the height of the auditorium can not meet the requirements, high poles or lighthouses should be installed at an appropriate distance from the four corners of the field. The position and height of the light poles should meet the following requirements: ɑ>5°, β>10°, γ<25°, θ≥25°,
The light panel of the lighthouse should adopt a fixed structure. Thus it is convenient to adjust the projection angle of the lamp according to the design. Lightning protection grounding facilities shall be installed, and the grounding resistance shall not be greater than 10 Ω.
