The N3 is a national route that connects Johannesburg and Durban in South Africa. It is a very busy motorway with a high volume of traffic. The N3 Toll Concession (RF) Proprietary Limited (N3TC), who is responsible for managing this motorway, focuses its activities on ensuring safety, convenience and mobility for all users. They therefore decided to replace the lighting in and around De Hoek Plaza, Wilge Plaza, Tugela Plaza and Mooi River Plaza with LED technology to improve visibility and to reduce the operating costs.
As this was a retrofit solution, the existing high masts had to be used. Great care had to be taken to ensure that not too much weight is placed on the hinged high masts as this would make maintenance work difficult. Schréder’s applications team carefully calculated a solution where the lighting levels and light uniformity would be met whilst the N3TC could benefit from an energy-efficient lighting scheme.
The OMNIstar was the LED luminaire chosen to light the plaza areas. It offers a real alternative to luminaires equipped with high-power traditional light sources, with the added advantages of an LED solution: low energy consumption, improved visibility with a colour temperature close to daylight, limited maintenance and longer life.
The LEDlume-midi LED luminaires were installed for the adaptation lighting along the road leading to the toll plazas, as well as the bullnoses at the plazas.
One of the many advantages of LED technology is the reduced need for maintenance due to the long lifetime of the LEDs. This is a major benefit to toll plaza operations since this leads to fewer disruptions of traffic.
