Lighting in Design Q3 2018

HESTIA Mini LED luminaires on curved poles illuminate Richmond Park.

What is the optimum co- lour temperature for street lighting? That depends on who you ask, and what literature you read. Some might say 2700 K and others 6500 K. A recent study by the AMA on blue light in LED luminaires having a negative effect on human circadian rhythms and damag- ing our eyes in streetlighting applications was, in our opin- ion, utterly disproved by Dr Ian Ashdown, Senior Scientist at SunTracker Technologies Ltd, in one of his blogs in

How the design of streets could change in real-time Carlo Ratti Associati, working in collaboration with Alphabet’s Sidewalk Labs, has unveiled a design for a modular paving system namedThe Dynamic Street. Intended to make streets “reconfigurable, safer, and more accessible to pedestrians, cyclists, and tomorrow’s self-driving vehicles,” the project will be on display at Sidewalk Lab’s office and experimentation space in Toronto throughout the summer of 2018. Manifesting as a series of hexagonal modular pavers, the project explores the various patterns which can be created by reconfiguring modules, with a potential future of“ allowing a street to create an extra car lane during rush hour before, then turning it into a pedestrian-only plaza in the evening.” The prototype contains embedded lights in all 232 modules capable of communicating crossings, pick-up zones, and other uses. Potential also exists for each module to host a plug and play element, including poles, bollards, or basketball hoops.

2014, and by the following scientific publication: https://ec.europa.eu/health/sites/health/files/sci- entific_committees/scheer/docs/scheer_o_011.pdf. We would recommend 4000 K, as it has a nice ‘natural’ lighting feel without the blue wavelength being obvious to the observer, as is the case in luminaires of 6000 K and above. Yes, but mostly in the Western Cape – especially CapeTown – and Durban.We have recently installed LED street lighting on SimonVermooten Street and Atterbury Road near Menlyn in Pretoria to mention two. These are great examples of wonderful road/ street lighting applications which not only ensure safer driving environments, but also a general feel- ing of safer movement in the open for cyclists and pedestrians. We have a great and practical range of streetlight luminaires for almost every type of road that could possibly be found in this country, and the continent. In our LED range of luminaires, we use a wide variety of specially designed optics to ensure opti- mal and maximum spacing while still maintaining standards for street/road light applications. Our luminaires are optimised to meet and sustain the harsh environmental conditions they are exposed to, which include strong corrosive atmospheres, dusty air and surges. www.beka-schreder.co.za Are LEDs becoming the norm for street light- ing locally? Can you tell us more about BEKA Schréder’s range/s of street lights?
