BiLiner · Linear Lighting for Tennis

The BiLiner is a linear lighting system developed for tennis courts, an application where visual discomfort is felt immediately: a player following a lob looks straight at the luminaires. Its 70 degree asymmetric lens directs the flux onto the playing surface while keeping intensity away from the players' line of sight.

Courts and venues concerned

• Indoor tennis courts and air-supported structures.
• Lit outdoor courts, the IP65 protection allowing direct exposure to the weather.
• Padel and badminton courts, where the same glare constraint applies when looking upwards.
• Sports halls and gymnasiums with a linear layout.

Technical highlights

• 70 degree asymmetric lens: the asymmetric distribution allows the light lines to be installed around the edge of the court and to light the surface without sending light into the players' eyes or beyond the boundaries of the court.
• 150 lm/W: an efficacy that weighs directly on the operating cost of a sports facility lit for several hours a day, and that limits the number of lines to install to reach the target illuminance.
• 60 W and 80 W modules: two ratings for adjusting the installed power to the height of the roof structure and the level of play, from recreational to competition.
• IP65: dust-tight housing protected against water jets, compatible with jet cleaning and with condensation in unheated halls.
• IK08: impact resistance, essential where a struck ball can reach the luminaires.
• Osram driver and Philips LEDs: components from established brands, a point to check when comparing offers, since the driver determines the actual service life of the whole unit.
• Pure aluminium structure: heat dissipation determines how well the flux is maintained over time, particularly under a roof where the ambient temperature rises sharply in summer.

To size an installation, start from the available mounting height, the number of courts and the target level of play: these are the parameters that decide between the 60 W and 80 W modules and the number of lines.
