The primary Cause of glare - Clustered and inefficient Light
When it comes to playing on a platform tennis or tennis court, LEDs are considered a superior alternative to the traditional HV lighting systems. LEDs provide a more natural light, consume less electricity, last significantly longer, and turn on as soon as you flip the switch.
The first step when looking at platform tennis court LEDs, is to understand that not all LEDs are the same. Most LEDs are designed for other uses - such as a illuminating a parking lot. The problem with placing these types of LEDs on a platform tennis court is they are susceptible to creating too much glare. There glare issues are created by how they release their light and how the direct their light.
Excessive glare may not be an issue when driving in a parking lot, but on a platform tennis court, hitting overhead lob while looking into light head with excessive light is a problem. An ideal platform tennis lighting system delivers a similar lighting experience using less light (fewer lumens) and through a non-clustered element design.
Here is how our LEDs reduce glare....
1. the Design of the Face
On the face of our LEDs, the elements are separated into quadrants. By contrast, many LEDs have a face where the elements are clustered together into one grouping. Again, this subtle design difference is relatively meaningless when comparing LEDs for use in a parking lot, but when playing platform tennis it is a key differentiator.
2. Directing Light - positioning the face of the LED
The face of our LEDs is raised at a angle so that its light is directed onto the court of play. By contrast, many LEDs heads have a rigged attachment and are set onto the pole at a 90 degree angle. As a result, the face of this type of LED directs their light at the foot of the pole. To get a similar degree of light onto the court these LEDs must increase their light output (and brightness). In short, our raised head deign requires less light output (lumens), reducing brightness and glare.
3. Directing Light - light dispursion
Our Premier LEDs take light direction to a completely new level by having a customized dispersion pattern specific calibrated for a platform tennis court. The dispersion pattern (see below) of our Premier LEDs is more horizontal than other LEDs and results in a more efficient use of light. For example, the Standard Lighting System of our Premier LEDs generates fewer lumens than our Price Advantage LEDs, however they illuminate the court just a tad better.
These charts capture the light dispersion of three commonly used platform tennis lighting systems.
Box Lights and square Led fixtures
This picture represents dispersion pattern of a light head that equally distribute it light onto the court.
Stadium lights have a funnel design which greatly improves the playing experience by directing its light more efficiently onto the court's surface. Most stadium lighting systems however, run-off of 1,000w HV bulbs, which require significant energy to operate. Also note, they tend to work very well when new, but their bulbs will to generate an increasing "yellow" hue as they age.
Our Premier LEDs
Our Premier LEDs purposefully direct their light across a platform tennis court. This means their light is dispersed evenly and more efficiently - helping create the ideal platform tennis playing experience.
*These charts are for illustrative purposes only. Different stadium lighting systems and square LED fixtures will provide varying results and light dispersion patterns. Court lines are not drawn to scale and do not accurately represent how the dispersion of light would fall onto a platform tennis court.
