The dimmable LED lighting installation

The dimmable LED lighting installation on the A44 will save up to 40% of the energy consumed by the previous lighting on the highway, with a similar reduction in CO2 emissions. The total energy saving is expected to be around 180,000 kWh per year –equivalent to the energy consumption of 50 households.

The RWS also aims to use the A44 installation to learn more about the use of innovative LED-based lighting solutions on Dutch highways.

Philips installs LED lights along 7-km length of highway

“The aim for our collaboration with the Rijkswaterstaat is to implement lighting solutions that both save energy and require less maintenance work on the roads,” said Frank van der Vloed,Such technology could be applied to Led lamp the development of improved surgical and medical lasers, better countermeasure lasers used by the military, General Manager of Philips Lighting Benelux. “Together, we will help provide a safe night-time driving experience while helping to lower energy consumption.”

Philips says that the Speedstar LED luminaires are designed to ensure that all the emitted light is focused on the highway, significantly minimizing light pollution that can otherwise be distracting for local residents as well as animals.

A further benefit is that the longer lifetime of LED lighting, coupled with the ability to remotely monitor the installation via a central control, will help minimize maintenance needs. This will both reduce operational costs and improve traffic planning, to reduce disruption to road users.

Switching off is a false economy

In related news, Philips Lighting UK says that adopting modern street-lighting technologies such as LEDs and control systems offer potentially greater savings than simply turning the lighting off.The accidental experiment came just weeks before the county led light bulbs council is set to publish a new report on the future of the square.

Reductions in street lighting are seen by a majority of councils in the UK as an easy option to cut costs in response to local-authority budget cuts imposed by central government. Philips Lighting believes that this is a false economy, and likely to end up costing more than it saves.

“Three-quarters of councils are said to be prioritizing cuts in street lighting,” says Andy Gowen, Director of Philips Outdoor Lighting Solutions. “The UK has an estimated 6.9 million lights around the country, costing some £30 each to power,Motorist Ian Beesley added: "It was running really well — they should led tube leave the lights switched off." or £207 million in total.Second, as Badding and his team expected, they found ds マジコン that the new class of fiber provided more versatility not just in the visible spectrum, but also in the infrared -- electromagnetic radiation with wavelengths longer than those of visible light.He said: "Approaching it there fluorescent bulbs looked like there was going to be chaos. But because the car drivers had to think a lot more they seemed to be being more careful. On the face of it the simple calculation is, turn them off for 10 per cent of the time and save £20 million.”
