To understand the lighting layout of baseball and softball courts, we should first understand the size of the two sites. Baseball and softball are mostly outdoor courts.
The baseball field is divided into inside field and outside field. The inside field is also called square field. The inside field is composed of two sides of the street outfield in the inner boundary area and the other two sides of the outside boundary area. The size of the inner field is 27.5 x 27.5m. The outer field is fan-shaped. The distance from home plate to the outer field through second base is at least 121.92m, and the unexpected area of the outer field is 18.29m.
Softball is a kind of multi-directional air movement. It is also divided into inside field and outside field. The size of inside field is 27.5 x 27.5m, and the outside field is fan-shaped. The radius of the outside field is R=61-70m, and the area within the fence of 7.62m outside the field and the two sides.

1.The lamp layout of baseball field can adopt 6 or 8 lamp poles, or the led sport light can be installed on the street above the auditorium.
2.The baseball pole is located outside the main view angle of the four baseball blocks of 20 degrees. The pole should not be set in the gray part of Figure 2 below.
1. The lamp arrangement of softball field should adopt not less than 4 lamp poles, or the baseball field lamp can be installed on the street above the auditorium.
2. The lamp pole of softball field should be located in the range beyond 20 degrees of the main view angle of the four basement areas. The lamp pole should not be set in the grey part of Figure 1 below.
1. In order to ensure that athletes have a good light environment and reduce shadows, light requires three or four directions. Stadium lamp position, glare control, stadium lamp group, light beam expansion and installation height are all required. Stadium lamp position. The led stadium lamp position should be consistent with the direction of the match. Figure 1 shows the locations of “A, B, C”.
2. Glare control. Place the stadium lamp outside the players’ loyal sight. In Figure 1, a 20 degree zone is formed from the triangular area extending from each baseline of the infield.
3.Expansion of field light beam. The top of the defined beam should be at least 10 degrees below the lamp plane of the stadium.
4. Installation height of lamp pole. The minimum installation height of the sport ground light on all lamp poles is 21.3 m from the ground. Increasing the number of lamp poles requires increasing the installation height of the led stadium lamp above. In Figure 3, the height requirements of lamp poles in Area A, B and C are different, which can be calculated according to the following formula.
Zone A poles provide illumination to pitchers and infielders. “A” pole height = 90′ + (SETBACK / 2)
Zone B poles provide illumination to the infield and outfield. “B” pole height = d / 3 (d is the distance from the pole to the symmetrical separation line of the site)
The light pole in Zone C is located outside the fence of the field and provides illumination for the outfield. “C” pole height = the farthest projection distance of the luminaire on the pole / 2
Luminous efficiency is the main index of LED chip performance. It is calculated by pulling one watt of electricity.
Luminous efficiency measures how much visible light a light bulb produces. Usually in lumens.
We provide LED field lights with excellent performance levels. This will save you more money than the early LED course lights.
In addition to the cost of lights, we need to learn more about the cost of running baseball stadium lighting. Energy efficiency is identified by looking at luminous efficiency in lumens per watt or LM/W. Halogen lamps have powers of 10 to 20 lm/W, HID lamps 60 to 80 LM/W, and leds 120 to 150 LM/W, which means leds can provide brighter lighting for the same amount of power .For a large lighting site, the reduction in total power means a significant reduction in the annual electricity bill.
For 10000W LED high mast lights, operating cost = 100 000W x 7 hours x $0.25/1000 = $175 per day, $5250 per month .If halogen floodlights were used, this value would be 10 times higher due to their lower energy efficiency. Greatly reduced operating costs.
There are no ballasts for traditional lamps, and there is no need to change bulbs regularly, so there is almost zero maintenance. Labor costs in Europe and the United States are very expensive. So being able to have a near-zero maintenance product is a huge advantage for many projects.
The design of reasonable beam Angle makes the luminaire more evenly distributed on the field. Combined with the unique secondary optical light distribution technology, reduce the harm of harmful glare to athletes. Create a better evening sports atmosphere for users. In particular, some of the faster movement, if the light line of sight is not good, often can not reach the effect of motion.
The service life and efficiency of lamps depend on the location of installation. The lighting of the stadium is outdoors and is affected by conditions such as water and humidity. That’s why they have to be designed for wet places.
Wet spots where water flows, drips or splashes onto the lamp can affect the components. Lamps must be IP certified in damp places.
IPX6: Spray water violently, spraying water in all directions of the shell with no harmful effect, water flow rate of 100L/min, test time of 3min.
IP66 class lights will work in all weather conditions in stadiums and stadiums.
Finned radiator is used to absorb and discharge the heat of the chip. Compared to the traditional die-cast aluminum radiator, the efficiency is improved by 30% and can be converted from 80-90℃ to maintain around 70℃. Greatly reduce the speed of optical decay of the chip, and reduce the probability of damage to other components.
The Mecree LED team will first understand the site information, design the lighting simulation system according to your site requirements, design reasonable lamp poles (replace the site), calculate the production time and transportation time, finally evaluate the rationality of the cost with the user, and finally assist the user in the installation and debugging. No matter your site size or lighting level, we will provide you with the most professional service.

2000-200000USD. There are many levels of baseball courts. Generally, 4 to 8 units of 400W are enough if they are just for lighting up the field and entertainment activities at night. If it’s a venue that can hold tens of thousands of viewers and has high-definition television coverage, you need a lot of ballpark lights. And some specific places need to be designed to prevent glare, intelligent dimming, RGB atmosphere lights and so on. The total cost of such schemes will be relatively high.
20 to 50 meters. According to the standard design guidelines, the height between 20 and 50 meters is suitable for baseball activities, but some recreational venues, or some venues with insufficient construction costs, may appear below the standard height.Only reasonable height can give full play to the best performance of the lamps, so that the uniformity of the field can be improved, and the glare control can also be improved, which can also make the baseball activities more comfortable.
20,000-50000USD. The high school baseball field is generally a training field and a general competition field, so the illumination is required to be within 200-500lux. According to the size of the field and the height of the lamp pole, we can calculate the final required number of lamps, but we will always control it within the ideal range. This will keep users’ costs under control. Exists for every field to have an evening baseball game.
