Street Lights should be switched to LEDs – QUT

Over the past 3 years more and more people have made the switch to LED bulbs in their homes – now a Queensland research team led by QUT scientists wants Australia’s street lights to be switched over to LED’s.

A 12-month LED street lighting trial in Brisbane, Ipswich and Townsville has just wrapped up, with great results for the environment and the public purse.

Researchers switched over sections of street lighting to bright LED lights that exceeded the road lighting requirements of the relevant Australian Standards and still found power savings of up to a massive 82 per cent.

The trial was facilitated by the Guided Innovation Alliance (GIA) – a group pushing innovations in the electricity sector and made up of QUT, Ergon Energy, and SmartGrid Partners.

“Public street lighting is the single largest source of greenhouse gas emissions for local government in Australia and is estimated to cost councils more than $250 million a year,” said Dr Gillian Isoardi, a QUT researcher and lecturer in optical physics who is part of QUT’s Institute for Future Environments.

“Compared with High Intensity Discharge (HID) lights, LED street lighting offers significant energy savings of up to 60 per cent, demand reductions and large maintenance savings from long design life (up to 20 years).

“New advancements in LED street light control mean they can also be dimmed when and where appropriate, which can further increase energy savings to 80 percent.”

The study results will be discussed at a free forum for government and industry on Friday, October 21, at QUT’s Institute for Future Environments.

The LED street lighting trial was supported by grant funding from the Australian Government’s Clean Technology Innovation Program (CTIP), and supported by participating organisations including the Brisbane Airport Corporation, Townsville Community Council, Ipswich City Council and Queensland Department of Main Roads.

The October 21 symposium will run from 9am to 10.45am at QUT’s Institute for Future Environments on the Gardens Point campus and will be hosted by the Guided Innovation Alliance. It is booked out but will be livestreamed to the public.

Benefits to Council, to City, Community including impact on carbon reduction and alignment to the carbon neutral strategy:

  • The LED lights produce significant energy saving compared to the conventional lighting
  • The LEDs are virtually maintenance-free, requiring only minimal monitoring by maintenance staff, producing additional financial and labour savings;
  • It will manage the brightness of the street lights, and can automatically adjust based on periods of inactivity
  • The energy savings due to the dimming function accumulate over the full operating period to produce additional energy savings
  • Smart LED lighting has the potential to provide the benefits of traditional lighting whilst reducing operating costs, energy usage and carbon emissions that will help ACC achieve the outcomes of its carbon neutral strategy
  • It also has the potential to provide different lighting textures that caters to different events on a needs basis
  • The Real-time monitoring of street lights with automated fault detection alerts and programmable remote controls will enable quick turnaround times in terms of maintenance
