Tasman Bridge

Lighting Upgrade

The lights adorning the side of the famous Tasman Bridge in Hobart is a project that has been in the making for a long time. Decrolux Lighting is proud to deliver on such an icon of Tasmania. The Tasman Bridge is approximately 1.4 km long and has lighting under the pedestrian walkways, shining back onto the bridge structure. We needed almost 3km of LED light to relight it.

Planning began mid-2019 with Decrolux working closely with Industrial Fire & Electrical (IFE). The IFE team were already involved with ongoing works on the Tasman Bridge which included switchboard upgrades.

The designing process involved a light fitting that would equal the output of the fluorescent lights. So Decrolux get samples and a lighting control system made. Created a mock installation at the IFE workshop in Derwent Park and, after meeting with all the stakeholders - including the Traffic Management, Department of State Growth, and Electrical Engineers - few adjustments were made and it was time to light things up.

We partnered with Enttec, an Australian Manufacturer for the light-control system. Enttec was awesome to work with, and the LED mapping software gives endless flexibility, with good fail-safe features.

The way we have designed this light system is so that every 15-metre section can become a different colour. The lighting is RGBW, which in layman's terms stands for Red, Green, Blue, and White. The white LED is a 3000K colour temperature. This is the colour with which the bridge will be lit for the majority of the time.

The idea is to use the Tasman Bridge as a reminder of those special occasions and somehow to humanise the bridge. The debut project for this upgrade was Dark Mofo 2021. This project was exactly what Tasmania needed after a year of uncertainties caused by a worldwide pandemic.

“In the future, the bridge can be lit not only red for Dark Mofo but also pink for Women's Health Week, blue for Men's Health Week, purple for The Canes, and blue and white for North Melbourne Kangaroos.” completed Jared.

For this project, we used 1920 pcs of Chameleon 14W RGBW light modules 1500mm(L), 180 LEDs per metre, 12mm Rigid PCB, Custom Aluminium Extrusion. 100 pcs of Meanwell 480W Power Supplies were used, which powers the LEDs and decoders.

We also installed an S-Play main controller, with the light scenes already programmed. And last but not least, 8 Pixelators - Signal Boosters – approximately every 300m, and 200 P-link CVC4 Decoders, one every 15 metres.

All to reach the desired effect we were aiming for. “The bridge now can do more than just connect both shores of the Derwent River, it will be able to dialogue with all Tasmanians,” says Jared.
