2013 VIC/TAS IES Commendation Award Winner: Larissa Underpass Feature Lighting by Webb Australia

Larissa underpass is a small pedestrian, cycle access route beneath the Ringwood Bypass in Ringwood, connecting Larissa Avenue and Suda Avenue.

THE CONCEPT BRIEF 

The brief was simple, illuminate the interior of the underpass and make it colour full, dynamic and safe for users. All options could be considered. Vandal resistance of the installation was of paramount importance

THE CONCEPT DESIGN 

The concept was to provide a dynamic, animated and colour full display to illuminate the walls of the underpass with colour changing computer programmable luminaires.

Security lighting to provide way finding and facial recognition would be addressed also by means of white light luminaires strategically located to illuminate people without distracting from the colour full wall display.

THE ENGINEERED SOLUTION 

Strip LED RGB luminaires are located in the small gap between the roof slabs. A total of 56 one (1) meter long strips(112 total) are deployed along each side of the underpass. “Coolon LED Lighting” provided the luminaires and control system. Vandal resistance was achieved by using a void filling polymer material and topped with non-pickable silicone sealant to secure the luminaires.

Each pair of LED strips has its own DMX driver. Each DMX driver was connected to an outdoor cabinet that housed the “CoolDMX Controller”. A 240 volt power supply was derived from a Council power pillar adjacent.

The DMX controller uses the “Coolon” software, “Coolonlight Architect” for programming of the luminaires.

Movement detectors mounted at each portal provide the initiation of the programmed sequence of the luminaires.

The installation was executed by “Ultralec” electrical contractors.

The client requested 50 sequences to be programmed and run at random.
