In tribute, flags have been flown at half-mast, and around Melbourne, many people placed blue ribbons on their front gates and fences.
And a number of city buildings lit up blue to remember the fallen officers.
Of course for this to happen, appropriate lighting equipment needs to be available.
One of the most prominent buildings involved was Flinders Street Station.
In 2018 a new external lighting system was commissioned as part of the $100 million refurbishment of the station, replacing older floodlights.
The lighting system of 1100 lights can illumine the station in any possible colour and will allow for the running of light shows for major events.
Created by Melbourne company APEC Electrical and their supplier Darkon, the lights are connected via 20 kilometres of cabling, allowing the system to operate automatically and by remote control. In a first for an Australian heritage building, each of the 1100 lights is networked through its own internal microprocessor.
Each light has a custom made amber LED that replicates the colour of the original flood lights, while only using a third of the energy of the old system.Rail Express – New LED system lights up Flinders Street Station
The lighting supplier Darkon also has information about the project on their web site, and they’ve got a demonstration video showing off the capabilities of the lighting system, which includes animated colours as well as static. Clever stuff.
Related to the upgrade of exterior lighting – which is lovely to look at, but doesn’t really directly help passengers – were upgrades to the lighting inside the station, including on the platforms.
This had to take into account the risks of too much light in the wrong places:
A number of luminaires were identified as possible candidates, with each included in a detailed 3D model to help ensure glare, reflectance and shadowing wouldn’t interfere with CCTV equipment or disrupt train driver’s vision of their surroundings, including signalling.
After a brief trial and feedback from a range of stakeholders, the decision was made to roll the Cree CPY Series out across the entire project. In order to maintain Flinders Street Station’s heritage appeal, it was decided a correlated colour temperature (CCT) of 3500K would best suit the project; warm enough to match the station’s architecture, without affecting safety and visibility along the platforms.Advanced Lighting Technologies – Flinders Street Station
It’s not immediately clear how much money was spent on all this new lighting as part of the broader project. But it seems to have been a worthwhile upgrade, and during a major refurbishment was the right time to do it.
While the external colours of the station don’t make the trains run on time, this capability does help cement the station’s place in our city’s culture.
And it ensures that what is perhaps Melbourne’s most prominent city building can help us celebrate in the good times – or as at present, help mourn the tragic loss of four police officers who were doing their jobs, helping to protect all of us.
