Light up the sports field (the ultimate guide)

With the increasing development and popularity of sports and competitions, more and more participants and people watching the game, the requirements for the lighting of the sports field are also increasing. Sports field lighting facilities must ensure that athletes and coaches can clearly see all activities and scenes that take place on the playing field so that they can achieve ideal performance, and spectators must follow the athletes and the game in a pleasant environment and comfortable conditions. When the lighting facilities of the sports field are turned on, how many lumens does the entire field need to reach? Maybe you can find the answer you need below.

Whats lumen?

What’s lumen?

The circumscription of lumen

Lumen is the international unit of luminous flux, which is defined in terms of the candela spherical angle (cd times sr). A point light source with a luminous intensity of 1 candela (cd), the luminous flux emitted within a unit solid angle (1 steradian) is "1 lumen", the English abbreviation (lm).

The differences between lumen and illuminance (Lux)

The difference between lumens and lux units is considering the area of the light flux lux diffusion or not. If the luminous flux of 1000 lumens is concentrated in an area of 1 square meter, the square meter will be illuminated with 1000 lux illuminance. The same 1000 lumens, distributed on an area of ten square meters, only produces 100 lux dimming. Their relationship is, 1 lx = 1 lm / m2.

How to calculate the lumen of led sports field light?

When you know the luminous efficacy of led lights and total wattages it needed, you can calculate the total lumens of the whole sports field. For example, the luminous efficacy of the led lights is 155LM/W, so the total lumen of 1300W will be 1300W x 155LM/W=201,500 lumens.

In addition, there is another way to calculate lumens. You need to know the illuminance you need and the size of the venue to be illuminated. From this, we know how many lumens the entire venue needs. For example, the area of a tennis court is 100 square meters, and the required illuminance is 300lux, so the total lumens required is 30,000 lumen.

Calculation with square meters

The beam ΦV in lumens (lm) is equal to the illuminance Ev in lux (lx) multiplied by the surface area A in square meters (m2):

ΦV(lm)=Ev(lx) x A(m2)

The luminous flux ΦV in lumens (lm) is equal to the illuminance Ev in lux (lx) multiplied by 4 πtimes the radius r of the square sphere in meters (m):

ΦV(lm)=Ev(lx) x (4⋅π⋅r2(m2))

Calculation with square feet

The luminous flux ΦV in lumens (lm) is equal to 0.09290304 times the illuminance Ev in lux (lx) multiplied by the surface area A (ft2) in square feet:

ΦV (lm) = 0.09290304 x Ev (lx) x A (ft2)

The luminous flux ΦV in lumens (lm) is equal to 0.09290304 of the illuminance Ev in lux (lx) multiplied by 4π times the square sphere radius r in feet (ft):

ΦV(lm)= 0.09290304 × Ev(lx)x(4⋅π⋅r(ft)2)

How to convert lumens into watts?

In addition to the lumens, wattage also need to pay attention. The wattage is very important and related directly to the electricity bill you paid. The higher the wattage, the higher the electricity bill you have to pay. When you know the lumens, how can you know how many wattage will you need to take?

Before converting, you need to know the luminous efficacy of the led lights. Because lumens are calculated from luminous efficacy and wattage. In other words, the luminous flux ΦV in lumens (lm) is equal to the power P in watts (W) multiplied by the luminous efficiency η in lumens per watt (lm/W): ΦV(lm) = P(W) xη(lm/W).

Therefore, the calculation formula from lumen to wattage is : watts = lumens / (lumens per watt) or W=LW / (LM/W)

For example, What is the power consumption of a lamp with a luminous flux of 51,200 lumens and a luminous efficiency of 160 lumens/watt (lm/W)?

P=51200 / 160 =320W

How many lumens are needed on the sports field?

Nowadays, there are various kinds of sports, and all kinds of sports grounds are also born. For different sports fields and different uses, their lighting requirements have also changed. Here are lighting requirements of some outdoor sports fields.

Stadium & sports field

When the sports field is not used solely for a certain sport and the main purpose is uncertain, you can refer to the following:

Take 100 meters long by 64 meters wide as an example.
