When buying a new LED sports lighting , you will have the choice between two different light beams: symmetrical or asymmetrical. This technical feature plays a key role in creating an optimal lighting effect, especially in areas such as stadiums, theaters or even streets.
In this blog, we invite you to learn more about asymmetrical lighting , in order to optimize the light output and use the full potential of your light.
Asymmetric lighting: everything you need to know
- Symmetrical luminaires distribute light evenly in all directions
- Asymmetrical luminaires direct light forward where it is really needed
- Advantages of asymmetrical lighting: glare-free and low light pollution
- Areas of application: stadiums, gymnasiums, theatres, car parks, streets…
What is the difference between asymmetrical and symmetrical lighting?
The symmetrical lighting distributes the light evenly in all directions. This type of light beam is recommended for the general lighting of large spaces but also for accent lighting that allows you to highlight specific objects or areas. We can take the example of symmetrical LED floodlights which offer high luminosity, are available in different color temperatures and have special protection
devices against external influences. They can therefore also be used outdoors.
Asymmetrical lighting, on the other hand, directs light in one direction. The glare effect is avoided, which is why the asymmetry in the distribution of light is an effective solution for the lighting of offices : it does not produce direct glare which can cause long-term eye fatigue. This is essential, especially when working on computer screens.
You are probably familiar with asymmetrical light from the automotive sector. Car headlights always work with asymmetrical light: the right headlight is directed forward in such a way that the right side of the road is better illuminated when the headlights are low. This ensures increased safety when driving because not only do you get a better view, but you also prevent oncoming drivers from being dazzled and annoyed while driving. You can see the effect of asymmetrical light, for example, when you illuminate a white garage door with your vehicle in the dark.
Where to use asymmetrical lighting?
Asymmetrical luminaires can be used in many areas of application, both indoors and outdoors, in gymnasiums, theaters, but also stadiums, car parks and for public lighting .
While symmetrical lights produce both direct and indirect glare, asymmetrical fixtures such as asymmetrical floodlights are designed to reduce indirect glare and sharp shadows. When installed in workplaces, they facilitate the transition from dark to light, allowing the eyes to work in comfortable light. Therefore, when asymmetrical lighting is used in stadiums, for example, the general lighting will be favorable not only to the players, but also to the public.
What are the advantages of an asymmetrical light beam?
Asymmetrical luminaires have integrated advanced optics which allow the light beam to be directed towards a selected area. The most common devices are called “reflectors” or “parabolic” because they use a reflective surface capable of reflecting and concentrating the light beam. This means that with asymmetrical devices it is possible to achieve the same visibility as traditional devices with significantly lower energy costs. Light emission is not wasted in areas where it is not needed. In doing so, this lighting technology has made it possible to reduce the number of luminaires required for the general lighting of a space as well as the related energy costs.
