Lighting : LIGHTING August-September 2017
40 LIGHTING MAGAZINE | August/September 2017 August/September 2017 | LIGHTING MAGAZINE 41 through their bluetooth help app, the smart module also has features that are helpful to lighting designers and operational mangement. The design features consist of the ability to tune the light colour to optimally fit the painting that is being illuminated, has options for dynamic light intensity adaptation depending on the ambient light situation or presence detection, as well as having options to regulate exposure time and light dosage, typical criteria relevant to long term conservation management. This allows the lighting designer to plan, tune, adjust and program these options as part of the overall lighting design. From a monitoring point of view there is a realtime feedback of the lighting intensities in use, as well as power consumption, voltage fluctuations, temperature variations over time. It also provides valuable information about the actual operating hours and signal strengths. TIME FOR SOMETHING TOTALLY DIFFERENT While all these smart features may have a very positive impact on the world we live in, there is one thing that needs a totally different approach... how can we be smart with the limited resources of our planet! Today’s lighting market model is based on a waste economy: z Products are developed and sold as a solution to a problem z Products are designed to fail with only a limited warrant z Manufacturers (and suppliers) are profit driven z As a result we are confronted with poor quality issues z The end-user bares all the responsibilities (and the costs!) In the end the products are discarded after useful life (waste disposal) LIGHT AS A SERVICE The answer lies in a totally new approach called “Light as a Service”, sometimes also referred to as “Pay per Lux”. Service driven models are already heavily involved by offering “free” test installations on stretches of roads to wet the appetite. Though many of these installations seem to be “politically motivated” and not necessarily cost efficient at first they appeal to the general public. But there are definitely lots of merits to smart city lighting, specifically the development of smart poles that integrate many more functions then lighting alone. Lighting functions may include street, pedestrian and façade lighting. Signage, wayfinding and promotional banners may be in the form of digital displays, internally lit signs or externally lit banners. Non-lighting functions can be much more extended; Wifi transponder, CCTV cameras, speaker functions, emergency call station but also charge points for cars, bikes or mobile phones. Linked to a smart grid, these poles may have photo-cells, light or proximity sensors to regulate lighting levels (dimming) or provide on-demand lighting. Proximity sensors within a wireless network may regulate lighting when cars or pedestrians are approaching. At the same time the smart features provide real time tracking of energy consumption, lighting failure monitioring and may also be used to monitor traffic flow. SOLAR ENERGY If we further expand the opportunities by including solar power to the poles it is easy to see how this can potentially revolutionise the world of outdoor lighting. Many pole concepts with integrated solar panels have been explored with mixed results so far. SMART FUNCTIONS AS A DESIGN AND MANAGEMENT TOOL Xicato recently launched a pilot project in the Van Gogh Museum in Holland using their latest Intelligent Module Generation 4 Module. While able to provide smart features such as wayfinding, indoor location information and background information on the paintings that one is looking at well known to the general public, just think of the Ricoh or Canon copy machines in your office, Uber taxi’s, Air BnB and air travel in general. In all these cases you don’t own the product, you use the product as a service and you pay a service fee for the usage. This concept has already found its way to fridges and even jeans, where you pay a monthly fee for using a pair of jeans which you can return within a year or exchange for a new pair of pants. Light as a service is being pioneered today in a few pilot projects in Holland by a consortium that includes Philips. The characteristics of this model are: z Pay per use instead of paying for possesion z The lighting installations are state of the art with smart and dynamic LED lighting z The lighting is human centric z The materials remain in possession of the manufacturer z The lighting installation is a turn-key solution which includes installation, maintenance and upkeep z The manufacturer is responsible for repair, re-use, refurbishment and recylcing z The manufacturer may also pay the electricity bill z The arangement is for a pre- determined contract period The two pilot projects in Holland are an office building and a recently renovated part of Amsterdam Schiphol Airport. THE CIRCULAR ECONOMY Moving from a waste economy to what is called a circular economy is a win-win situation for everyone. In this market economy model we have: z Lighting is a service, not product driven z Assured performances with minimum failures z Re-usable products with minimum waste z Minimise the environmental impact with a reduced carbon footprint z A one stop solution (ownership) with minimal capital outlay for the end user z The latest technology that stimulates innovation It is time we start thinking smarter when it comes to lighting design. It is not only about adding smart features to lighting solutions and in the process making lighting designers less relevant. It is time to start thinking smart and differently as remember, there is no Planet B! Figure 9. The Paris metro is trialling LiFi at some stations (image: Oledcomm). Figure 10.
