There are 3 principal options for LED sports lighting geometry: - Symmetrical, Hybrid and Asymmetrical. Symmetrical lightingIn a symmetrical lighting system the primary output is perpendicular to the light body and its LED source.Symmetrical products are the simplest to produce and having the most direct light path are the most efficient. Symmetrical products are recommended for all indoor applications, lighting of enclosed sports stadia and small area outdoor lighting; provided that the included angle for the lighting can be kept below Ɵ ≤ 50°.
Hybrid LightingHybrid products have multiple LED source surfaces (in one or more body parts) which can be arranged to provide a variety of output results. They are usually slightly less efficient than plain symmetrical products and can be more complicated to set up.Hybrid products are recommended for small area outdoor applications, such as tennis, which may have restricted surrounding area requirements.
Asymmetrical LightingAsymmetrical products have a primary output that is at a significantly offset angle from the light body and its LED source. Their complex light path is difficult to produce and less efficient, so these products are reserved for specialised applications.Asymmetrical products are recommended to minimise light overspill and luminaire intensity for neighbours, when lighting large open sports fields such as used for amateur football and rugby.
