STREET AND exterior lighting was one of the first sectors to widely switch to LEDs.
And while the subsequent energy savings have widely appreciated, that move has thrown up some fresh challenges that are set to keep engineers on their toes this year. Here we run through the top concerns facing the sector in 2018.
The issue that won’t go away. It’s becoming widely acknowledged that too many fixtures with poor optical control were installed in the first wave of LEDs. Cool colour temperatures – 5000K in some places – have also proved deeply unpopular with residents around the world.
3. Electric vehicle charging
The average municipality think its street lighting network is the perfect solution to the provision of charging points for the coming wave of electrical cars. It isn’t. Technical issues abound – not least the high-current draw – and street lighting engineers won’t be popular for pointing them out.
5. The Great Switch Off
The deeply unpopular switching off of street lights by cash-strapped local authorities is still causing ripples and it continues to be blamed for accidents by the police and coroners. Dimming is the solution that lighting controls manufacturers propose, but getting funding is a headache.
7. Smart Cities
Mayors love the idea of their metropolis becoming a ‘smart city’ and while the phrase sounds cool, no-one knows quite what it means, least of all the people who are supposed to implement it. But everyone does agree that lighting is involved. At the very least, expect some sensors in your street lights.
9. The lack of strategy
It’s hard to plan for the next 30 years of urban illumination, which is why street and exterior lighting engineers like a strategy. You know, a clue where we might be heading. Famously, the London Plan mentioned lighting a mere six times in its 526 pages. Which leads us onto….
- Lux has unveiled the programme for its Lighting for Transport and Infrastructure conference, taking place in London on Thursday 22 February 2018. It includes sessions on glare, light pollution, electric vehicle charging on street lights, street lights asset management, IoT street lighting control and LEDs and mesopic vision. Places are free of charge to those responsible for street lighting assets. To view the programme and register, click HERE.
