LED stadium lights

When we watch a game or a sports game, we will find that the stadium lights will be brighter. Just like white. So you know, what is the luminous flux of stadium lighting? How to calculate the luminous flux? Perhaps the following article will answer this series of questions for you.

What is Lumen?

The so-called lumens refer to a candlelight (cd, Candela Candela, the unit of luminous intensity, equivalent to the luminous intensity of an ordinary candle) corresponding to a solid angle of 1 square meter on a unit sphere with a radius of 1 meter. The angle represented by the sphere cone, which corresponds to the total emitted luminous flux produced at a central angle of the central section of about 65°. Considering that the solid angle of the entire sphere is 4π, the total luminous flux of 1 candle is 4π (about 12.57) lumens. The total solid angle of the ball of any size is 4π, so the total luminous flux of the candle light is fixed at 4π, and does not change due to the change of the distance. Therefore, "the total luminous flux emitted by a candlelight at a position of about 0.28m around it is 1 lumen" is a misrepresentation. Popularly speaking, it is the brightness value.

How to calculate Lumens of LED stadium lights?
Lumens are the units of luminous flux. Luminous Flux The total amount of light emitted from a source, expressed in F. Its unit is lumens (Lm). A point light source having a luminous intensity of 1 canopy, the luminous flux emitted in a unit solid angle (1 steradian) is "1 lumen".

Razorlux LED stadium lights is range from 200w-1200w, and the lumen of the LED stadium lights are 24000lm, 36000lm, 48000lm, 72000lm, 96000lm, 144000lm.

 

Lumen is Lumen, so what does this Lumen mean?

 

Well, Lumen seriously said that it actually represents the intensity of light, that is, Luminous Flux (the total number of rays emitted by a light source in a unit of time, generally called a beam), in short, in short Lumen is the amount of light that shines on the surface of an object.

The distinction between high-power LED1W and 3W is the size of the chip. Generally, 1W is less than 35 MIL, and 3W is a chip larger than 40 MIL. There is no difference in the package method. The current is determined by the magnitude of the current to be 1W or 3W. The high or low lumens value depends on the source of the chip used.
At present, 1W is mostly 80-90-100LM, the lumen value of 3W is 1.6-1.8 times of 1W, and the lumen of warm white (3000K) is 60-70% of cool white (6500K).

The lumen value of the LED is the value of the standard detection current 1W350MA/3W700MA. The actual application is generally not higher than 1W300MA/3W600MA, and the corresponding lumen is indeed a coefficient less than 1 (up to 0.8). Of course, the integrating sphere data can be used. For the best.

1. Lux.
This measures the amount of light per square meter. Basically, it gives you an idea of the size of the area a light can illuminate. Lux is important as it tells you how many bulbs you’ll need to cover a particular area.

To give you an idea: 1 lux is equal to how much illumination a single candle can provide from approximately 3 feet away.

2. Wattage.
This measures the amount of electricity a light bulb consumes. For example, a 100-watt bulb consumes 100 watts of electricity every second it is on. The higher the wattage, the more electricity you’ll pay for.

If you have a lot of outdoor lights to install (i.e. a high wattage demand), you may need an electrician to install a new circuit.
