Softball is developed from baseball and has similar rules. As with any large-scale lighting project, lighting a softball field is a very large project. Regardless of the level of the game, the lighting of the softball field must ensure that every area on the field is evenly illuminated, and any lamps or radiated light will not interfere with the progress of the game. Because a softball game includes a small object that moves at a very fast speed, the lighting must be much stronger than the lighting for football.
Softball field lighting
1.Softball field lighting definition
The softball field is named "Diamond Field" because of its unique right-angled fan shape and the beam of lights illuminated at night. It looks like a shining diamond from the night sky. It is well known that the lighting system of the stadium at night is very important for the progress of the game. The arrangement of the lamp posts, the angle and area of the lighting are very particular.
2. Softball field size
To understand the field lighting of a softball field, we must first understand its field size. Softball is mostly an outdoor court, which can be divided into an inner field and an outer field. The size of the inner field is 27.5×27.5m, and the outer field is also fan-shaped, with a radius of R=61~70m, and the area within the 7.62m fence outside the outer field and both sides.
3.Softball field lighting standards
Softball field lighting design needs to be designed with reference to the illuminance level, illuminance uniformity, glare limit, color temperature and color rendering index of the softball field lighting.
- Illumination level
The standard value of illuminance for the general softball game field is 750lx, the average level of illuminance of the referee's podium area is not less than 200lx, and the minimum average level of illuminance for the auditorium is not less than 50 lx,
- Illumination uniformity
The ratio of the minimum to the maximum level of the field level illuminance is not less than 0.4, and the ratio of the minimum to the average value is not less than 0.6.
- Glare limit
Combining the architectural plan and lighting arrangement, the measures to prevent glare include: avoid installing the lighting above the sports field, and use professional lighting with low glare design.
- Color temperature
Color temperature is a characteristic that visible light has important applications in photography, video, publishing and other fields.The color temperature of general softball field lighting should be 5500k, so that it can simulate natural light as much as possible ，so as to give people a sense of comfort .
