Car park entrances are a dangerous place. When entering a car park, a driver’s eye must adjust quickly, adapting from the bright daylight conditions to the darker car park environment. This transition can lead to a temporary blinding, making it difficult for the driver to react to obstacles or pedestrians. Car park entrances can often be located in high pedestrian areas, this temporary loss of clear vision is enough to create serious injuries.
Australian Standards (AS 1680) specifies 800 lux for the first 15 meters of a car park entrance during the day and 160 lux at night, followed by 160 lux for the next 4 meters at all times. This helps transition the lighting level upon entry and reduces the effects of blinding.
The wireless car park entry system (CECS) comprises of RF enabled Tauro Black LED high bays, a twilight sensor and an RF controller placed at the car park entrance. The twilight sensor assesses the outside light level via a photo electric (PE) cell and the controller communicates with the lights via a self-configurable wireless mesh to deliver 800 lux during the day and 160 lux after dark.
This mesh network is self-healing in nature, every light talks to the controller and amongst themselves. If a light loses communication with the controller, it can still tether to the nearest light to reconnect again to the control signal.
Commissioning is simple and requires no complicated network setup. The smart controls system combined with the LED lights also reduces the energy and maintenance costs.
