Chiltern Railways zaps energy binge with LED overhaul

Chiltern Railways was in desperate need of a cost slashing innovation to reduce energy usage and an inventive application of LED technology offered the answer.

The Arriva owned company has updated the internal and external lighting at three major stations, Wembley, Aylesbury and Stourbridge in the south of the UK.

Energy-intensive 400W highbays at the Wembley and Aylesbury maintenance depots were replaced with hooked LED highbays in a range of wattages and a sustainable, higher efficiency, longer lamp life replacement for traditional 2D bulk heads, was installed in the staff shower and toilet facilities at Wembley.

The offices on both sites were kitted out with ultra slim ceiling panels that deliver high performance and attractive LED lighting. Fluorescent tubing has also been removed and replaced with highly efficient non-corrosive LED fittings, to act as a lower energy consumption alternative.

The LED highbays installed at the Wembley and Aylesbury maintenance depots delivered a 67 per cent and 48 per cent saving in energy consumption respectively. Both sites also realised a further 64 per cent reduction in energy usage thanks to the new ceiling panels.

A mix of LED amenity, street and area lighting products were also installed to deliver optimum illumination in a number of outside areas, including pathways around and access roads to the railway tracks.

A further thirty flood lights were installed to illuminate the tracks at the Stourbridge site and another 285 replaced the legacy 40W twin CFL lights along the pathway running adjacent to the railway track at Wembley.

In all three locations, this provided Chiltern Railways with a low power, high quality LED replacement for the incumbent energy-intensive flood lighting.

Emergency lighting at Wembley which had proved to be problematic, was also upgraded.

At Stourbridge, replacing the energy-intensive legacy lighting alongside the tracks with flood lights resulted in a 62 per cent reduction in energy consumption. Furthermore Chiltern Railways will achieve an average 61 per cent reduction in CO2 emissions.

In addition, Chiltern Railways no longer has to factor in time or budget for maintenance. Chiltern Railways estimate they will benefit from a further reduction in spend of around £10,000 per annum, the amount it previously cost to maintain the lighting infrastructure.

Another benefit has been a dramatic improvement in the quality of light. The external areas are now brighter, more secure and offer safer working environment for the company’s employees.

The superior uniformity of light and improved illumination within the offices, has also been well received by Chiltern’s staff.

 The potential decision to sell of the firm’s prestige lighting business will come as a surprise to some, especially as lighting, in the early days of the company, defined GE.

 

GE is thought to be considering selling its lighting buisness so it can concentrate on producing large complex equipment such as aircraft engines.

GE, the company credited with inventing and mass marketing the lightbulb, is reportedly plotting to sell of its lighting division.

The Wall Street Journal reports that the firm has been talking to a number of investment banks about a potential deal.

GE was co-founded by Thomas Edison, the inventor of the first viable incandescent lamp, over a century ago and the jettisoning of the firm’s lighting business a century later could net the company up to $500 million.

The Boston based company has been gradually selling off businesses since 2004, including its insurance, credit card, plastics and security divisions.

It is thought that GE is taking these actions so it can concentrate on producing large complex equipment such as power turbines, aircraft engines, health-care equipment and trains, while gaining a considerable income stream from the very lucrative service contracts that go alongside developing these machines.

Nevertheless, the potential decision to sell of the firm’s prestige lighting business will come as a surprise to some, especially as lighting, in the early days of the company, defined GE.

GE has so far refused to comment on the rumours.

LEDs found to increase yields in wide range of plants

Research found that 32 days after they were planted and nourished under LED light, tomato plants showed a 45 percent increase in height and a 28 percent increase in weight.

Improvements in weight, morphology, flowering, root development and flavour have been spotted in plants grown under supplemental LED lights in greenhouses.

Tomato plants have been found to show a 45 per cent increase in height and weight when cultivated under LED lights.

The new research, which was conducted by LumiGrow, who develop LED technology for use on farms, noted an increase in flowering observed in cucumber plants, as well as a reduction in the spread of powdery mildew, which is a common problem.

Increased flowering rates were also found in tomato and cannabis plants. The research also aimed to pinpoint the optimum supplemental LED light intensity for strawberry production.

The research was presented by Dr. Xiuming Hao and Shalin Khosla of Harrow Research and by Dr. Melanie Yelton, who is vice president of research at LumiGrow, to an exclusive grower’s council at Harrow Research and Development Centre.

A broad range of growers made up the audience, including vegetable, floriculture and cannabis producers, all looking to take full advantage of the LED revolution in horticulture.

The research found that 32 days after they were planted and nourished under LED light, the tomato plants showed a 45 percent increase in height and a 28 percent increase in weight.

Improvements in weight, morphology, flowering, root development and flavour were also spotted.

LumiGrow’s inventive Grow Light Sensor technology was also displayed and discussed at the meeting. The sensor is able to measure and monitor ambient light from the sun and then analyses this collated information to decide how much supplemental LED light is required in the greenhouse to keep conditions consistent.

Here comes the moon: CoeLux launches night version

 ‘The moon, unlike the sun, lets you look at her, it seems she wants to be looked at’, commented Paolo Di Trapani, CEO of CoeLux, who is behind the latest innovation.

 

CoeLux Moon aims to create a comforting and relaxing ambience and less light is used to produce the final effect than the original sunlight CoeLux uses.

CoeLux’s artificial skylights have rocked the industry due to their convincing reproduction of sunlight. Now the company has launched a new version that aims to be just as successful at recreating the night sky.

CoeLux Moon is being launched at Euroluce 2017, which is currently taking place in Milan.

‘The moon, unlike the sun, lets you look at her, it seems she wants to be looked at,’ commented Paolo Di Trapani, CEO of CoeLux, who is behind the latest innovation.

CoeLux chose last year’s LuxLive to launch the second generation of the CoeLux daylight range, which is comprised of smaller less costly fittings.

‘By rebuilding the physical mechanisms that happen in the atmosphere we have ended up with a product that allows people to feel the same as they do when they look up at the real sky.’ Di Trapani continued.

CoeLux Moon aims to create a comforting and relaxing ambience and less light is used to produce the final effect than the original sunlight CoeLux uses.

The potential health benefits that might be derived from using CoeLux are still being investigating by the company.

CoeLux claims to have psychological and physiological data on the capacity of people to relax and feel calmer when using CoeLux and it might even possibly be used to improve post-operation recovery times in hospitals.

‘We have evidence from the psychological ward at the San Raffaele Hospital in Milan, that people who have a room on the sunny east side recovered 20 to 30 percent faster from operations than those on the west side of the building,’ Di Trapani told Lux Magazine.

It will be interesting to see if CoeLux Moon has the same effect on wellbeing as the company’s original skylight.

Has Amazon conquered lighting control by stealth?

Amazon’s voice technology ‘Alexa’ forms the backbone of the firm’s Echo platform, but Alexa is also finding its way into a string of third party innovations.

The Amazon Fund have invested in a number of start-ups that aim to improve voice technology used in the home. The Fund  has already invested  in firms such as Musaic, a smart HiFi that allows users to integrate lighting with their playlists.

Amazon has launched a $100 million strong fund to fuel voice technology innovation, with the intention of ensuring it becomes the key tool used in home lighting control.

Named the Alexa Fund after the voice that assists users on the company’s Amazon Echo platform, the venture capital stream aims to fundamentally improve the way that people use voice technology, including to control lighting.

The Alexa Fund will offer financial help to independent developers and device-makers who wish to advance voice technology, be that through creating new Alexa capabilities, or by expanding the boundaries of voice technology through development and research.

As part of the Fund, Amazon has launched the Alexa Accelerator, which aims to encourage start-ups to bring their voice technology aspirations into a concrete reality.

Companies are chosen after a rigorous selection process and are then invited to take part in a 13-week program in Seattle, where they get the opportunity to work with leading technologists and product leaders from Amazon and Techstars.

The Alexa Fund has already helped a number of start-ups, including Musaic, a voice activated, wireless HiFi system that allows users to integrate smart lighting to react to a particular playlist or song.

Amazon were not present at the Consumer Electronics Show in the US last year, but Alexa could be found in numerous third party innovations that the company has invested in.

The Fund has also invested $35 million in the smart thermostat system Echobee, £5.6 million in the Alexa powered video intercom Nucleus and has made a further million-dollar investment in Rachio, a smart sprinkler system.

The Alexa Fund has been labelled as a ‘stealth takeover’ of the smart home market by Amazon and it is possible that future smart lighting apps and devices may be developed with Amazon money.

At major technology shows, such as the Consumer Electronics Show in the United States, Amazon were not obviously present. However, Alexa technology could be found in numerous third party devices from lighting systems, to home security cameras and cars.

Nevertheless, despite Amazon’s surreptitious attempts to conquer the smart lighting market, the company does face stringent opposition from the likes of Apple’s Homeworks, Google’s upcoming Brillo and Samsung’s SmartThings.

But for now, Amazon is the logical choice for third party Internet of Things start-ups looking for investment and that doesn’t look likely to change any time soon.

LED lamps and luminaires are commonly available in 2700K, 3000K and 4000K colour temperatures, but how do you go about choosing the correct colour?

This question has been answered by Chris Shenton, technical and quality specialist at LEDvance UK.

Lamp colour temperature is often a personal or historical choice and it depends on what environment is being created.

Here is a general guide:

2700K is a similar colour appearance to incandescent lamps and is a warm, relaxing colour.

3000K is a similar colour appearance to halogen lamps with a warm but crisper colour than 2700K. Commonly called ‘warm white’.

4000K is a cooler, whiter colour than 2700K and 3000K. It’s the lamp that has traditionally been used in offices, waiting areas and most commercial applications. This is commonly called ‘cool white’,  or occasionally ‘neutral white’.

6500K is a very cool white that is used to simulate day light. It is also said to increase productivity when used in a work environment. It is commonly referred to as ‘daylight’.

The warmer colours work well in more relaxed environments with warmer colour decoration such as in domestic living rooms, restaurants and hospitality areas.

The cooler colours work well to help create a lively environment with lighter colour decoration such as domestic kitchens, offices, warehousing and in retail spaces.

Now that we have the ability for colour ‘tuning’ via LED sources, the extremes of warm and cold white sources are being used as the basis for ‘human centric’ lighting installations. Mixing of the two extremes allows interior lighting schemes to be adjusted according to the needs of the occupants.

Novel Energy Lighting recently worked in collaboration with the facilities team at Holy Trinity Brompton on the LED lighting retrofit project at St Charles Borromeo RC church in London.

 We replaced 33 x old halogen floodlights with Design 360 Impact Surface Mounted 4000lumen LED spot lights. Lighting levels were increased and glare dramatically reduced. Gloomy corners of the church are now bright and welcoming. The project was a like for like swap, no changes to wiring were made, and all the lights were installed in 7 hours by 2 electricians.

    

 

     

The Church can now enjoy saving up to 90% on its lighting energy bills, and stop the maintenance call outs to change blown-out halogen bulbs high up ladders!

We have supplied LED lighting for many large churches, including St Charles Borromeo London, Holy Trinity Brompton (HTB) London, All Souls Langham Place London, St Augustines Brighton, Larkhall Baptist Church, Elim Church Dagenham, and many more.

Please call us to discuss the LED lighting needs for your church, we can provide volume pricing, lighting designs, and product expertise.

Ten retail indoor positioning projects you need to know

Indoor positioning projects in retail are now popping up around the globe.

Indoor positioning projects in retail are now popping up around the globe.

Indoor positioning is the next revolution that is set to reshape the world of retail. Be it Osram, Philips, GE or Zumtobel all the major players in the lighting world are developing their own interior navigation systems, that utilise bluetooth chips planted in lights or visible light communication (VLC) to send directional information to shoppers smart phones. The apps can then direct shoppers to special offers or products that particularly interest the shopper in question.

New indoor positioning projects in retail are now popping up around the globe and the initial results from these are often quite impressive. Here are Lux’s top ten indoor positioning projects that you need to know about.

 

10) Ginza Six Mall – Tokyo

Ginza Six is a massive 500,000-square-foot retail complex in Tokyo that is set to open in the next few weeks. Quite understandably some kind of guidance is going to be required to get shoppers around such a massive space and the owners have turned to indoor positioning to help.
 

StepInside, an indoor positioning system developed by Senion is being installed, which will show patrons the quickest route to a store via a smartphone app.

The mall is expecting up to 20 million people to visit the store every year, many of whom will be tourists unfamiliar with the sites layout.

The building’s management will use the data collected by the app to better understand the behaviour of visitors, helping authorities to develop better traffic flow management systems when the store opens.

 

9) CapitaLand Mall – Singapore

The CapitalLand Mall in Singapore is installing a Philips VLC based indoor positioning system.

Users are required to install an app on their smartphone and then allow the camera on their phone to pick up a light frequency emanating from the Philips lights installed around the mall.

The shopper’s location in the mall is then identified and directions are given, depending on where abouts in the estate the shopper wants to go. Retailers are also able to use the app to send out targeted marketing messages to shoppers.

 

8)E.Leclerc – Langon

Zumtobel joined forces with E.Leclerc Langon, a hypermarket in France, to launch an indoor positioning, smart parking and mobile push marketing app.

The existing lighting infrastructure has been adapted to offer the serrvices, by fitting the luminaries with sensors.

The Bluetooth beacons allows customer to locate their position and allows E.Leclerc Langon to send real-time push messages with customised offers, based on the customers current location in the store.

In the car park, the app can help a customer to locate available parking spots, or even find their way back to their car when they have finished shopping.
7) Tai Po Mega Mall – Hong Kong

Google has invested in several indoor location companies and the firm believes that that in time indoor positioning will be bigger than GPS, simply because people spend the great majority of their time indoors.

Google has created indoor maps of stores like the Tai Po Mega Mall in Hong Kong and other major worldwide retail destinations in preparation for the launch of the company’s head-mounted computer ‘Glass’ which will allow people to see directional arrows through glasses.

Although it is still early days, there is the potential for Bluetooth chips embedded in light fittings to be able to provide information to feed Google Glass in the future.

 

6) Carrefour – Lille

Carrefour in Lille steer shoppers straight to discounts via the lights in the shop ceiling.

The €84 billion ($93.4 billion) retailer transmits digital information from LED lamps to customers’ smartphones via VLC provided by Philips. The system uses 800 programmable Philips LEDs.

VLC is able to encodes lightwaves with data about products and promotions, and transmits the information straight to the camera on a shoppers’ smartphone.

An app then displays the directional information, which helps to guide the consumer to the product’s location in the sprawling store.

5) Walmart – US-wide

Walmart is thought to be trialling Acuity Brands indoor positioning technology.

Acuity Brands claims that it has now deployed lighting-based indoor positioning systems (IPS) in swathes of retail space across the US.

Acuity Brands is thought to be developing indoor positioning products in conjunction with Microsoft.

The two companies are developing products that utilise lighting to communicating information to to shoppers smartphones.

Data the app collects is then sent to Microsoft’s Azure cloud system to allowing retailers to discern useful retail patterns and insights.

 

4) Aswaaq – Dubai

UAE supermarket chain Aswaaq became the first retailer in the Middle East to install connected lighting which communicates with its customers.

Its Dubai branch boasts a VLC based indoor positioning system, which allows shoppers to find items in the store to an accuracy of 30cm.

Smart-phone owners must first download the Aswaaq-branded app, which allows their phone to communicate with the individual light points transmitting their location through the high-frequency modulation of the light.

The data stream is one-way and no personal data is collected by the lighting system.

 

3) Target – US wide

American retail giant Target uses LED ceiling lights to track in-shop customers and guide them to relevant products via their smartphones.

The system is widespread and has been placed in nearly 100 Target stores.

The $73 billion chain told Lux that the scheme uses wireless signals that travel between LED lights and shoppers’ Android gadgets to spread directions and information related to products and special offers.

The 100 location deployment marks the largest known deployment of indoor positioning by any retailer to date and offers a good sign that the system can work and be worthwhile on a wide scale.

 

2) EDEKA Paschmann – Düsseldorf 

An EDEKA Paschmann supermarket in Düsseldorf became the first store in Germany to benefit from the new Philips’ indoor positioning system earlier in the year.

In collaboration with Favendo, Philips has developed a new smartphone app that gives shoppers access to location-based services, helping them to find items in the store, down to an accuracy of 30cm.

A range of newly introduced downlights and spotlights have been installed in the store, which are compatible with the Philips way-finding technology.

As well as providing location services and in-pocket notifications about discounts, the technology can also be used to collect data about where are the busiest areas in stores and analyse the routes customers take to find products. This allows retailers to make better decisions when it comes to store layout and marketing.

The Philips Lighting Bluetooth low energy (BLE) beacons, which allow the location system to work, are easy to integrate as they come with multiple powering options ranging from full integration into luminaires to track-mounted beacons.
1) Marc O’Polo – Switzerland-wide

The indoor positioning system installed as part of a trial in Marc O’Polo stores in Switzerland saw the average value of purchases made by customers rise by 10 per cent, the best evidence to date that indoor positioning could well revolutionise retail.

Osram Einstone technology was commissioned by the Bollag-Guggenheim Fashion Group to try and improve customer loyalty, whilst increasing the chances that customers would purchase products. The company wanted to develop a mobile phone app that would serve as a digital customer loyalty card, which would offer discounts and special offers locally using indoor positioning technology powered by the lights.

The use of pastel coloured uplights in retail displays has been found to increase sales in a new study. The installation of the lights in a particular area of a store in Germany were found to increase basket values by six percent.

The same combination of coloured lights also increased customer visits to the revamped section of the store by 15 per cent when compared to an area lit with standard store lighting.

Philips Lighting produced the study in conjunction with major German grocer, Globus, with the expressed aim of finding lighting that increased sales.

‘As a retailer, to stay ahead of the competition, you have to create a multi-sensory environment and a ‘wow-factor’ in your stores,’ commented Norbert Scheller, store manager at the Globus supermarket in Saarbrücken where the experiment took place.

The researchers spent two months testing different lighting conditions in the supermarket. Three settings were tested, including the store’s uniform overhead lighting, regular spotlights and a combination of spotlights with pastel coloured uplights.

Retailers have traditionally lit stores using uniform, white, overhead lighting. The research showed that the 58 spotlights used in the experiment strengthened the appearance of products by increasing contrast.

Adding coloured uplighting, aimed at the ceiling,  also helped to differentiate the promotional zone, making it more visible.

LEDs are set to change horticulture by increasing yields

The colour of LED light can be used not only to assist the growth of plants, but it can also be used to improve their year-round taste and quality and potentially increase their nutritional value.

Not only this, but growing fruits and vegetables under LED light makes them less vulnerable to the threats of climate change. It is no wonder then, that interest in the role LEDs can play in farming is growing.

Lux spoke to Doctor Phillip Davis, business manager at Stockbridge Technology Centre in Yorkshire, who will speak at our Horticultural Lighting Conference, to find out what more can be done to speed up the LED revolution in farming.

The Stockbridge Technology Centre was originally a UK Government research facility set up after the Second World War to improve food production methods.

The site has survived through many changes, but it is now an independent industry owned site and registered charity, which delivers innovative R&D services to all sectors of the horticulture and agri-food industry.

Today, as the world population continues to grow, there is a real fear that we will run out of food. The role of the Stockbridge Centre in the twenty-first century is to bring forward technology that can improve food production sustainably to tackle the challenges of today.

‘LED lighting was technology that we recognised five of six years ago as being something that could really benefit horticulture,’ Doctor Phillip Davis, told Lux.

One of the greenhouses at the Stockbridge Technology Centre where tomatoes are grown beneath coloured LEDs. The glasshouse contains two types of  Philips LEDs. Top lights are located above the crop, which are used to replace the standard high pressure sodium lamps and LED interlights are located within the canopy to maximise crop light use efficiency.

‘There is a huge amount of interest across the horticultural industry in LEDs. This is not just because of energy efficiency, but because of the potential light has to manipulate plants.’

The ability to change the colour of LED light is crucial. 90 per cent of plant genes are regulated by light. So, by changing the light spectrum, it is possible to change how a plant grows, how fast it develops and its morphology. It is also possible to change the flavour, the aroma, the antioxidant content and, potentially, the amount of vitamins produced by a plant.

STC uses a plant’s natural biology to do this and does not not alter or play with their genetic make up in any way. Instead, it uses light to improve the yields, quality, as well as the taste of the product being cultivated.

Light can be used to ensure that the taste of fruit and vegetables is consistent throughout the year, for example, ensuring there are no differences in taste between a strawberry grown in season and one grown in winter.

‘We spoke to a restaurant chef recently who said that it is quite difficult to design a recipe if the flavour of basil changes throughout the year,’ Davis said.

‘The systems that we are talking about are never going to replace field crops. What we are going to do instead is add another layer of crop production into the current system, which is robust enough to survive climate change and adds security to the food chain.’

Dr Phillip Davis – business manager at the Stockbridge Technology Centre

‘We can produce the same quality basil all year round, meaning that every time you make a recipe you will need the same amount of basil every time.’

If the light environment is right, it is also possible to improve the rooting of plants when vegetative cuttings are taken. The right lighting can improve the strike rate of cuttings (i.e the number of plants taking root) from 20 per cent to nearly 100 per cent, meaning savings on labour and materials can be made.

More than a thousand commercial growers have visited Stockbridge to see the technology, but the use of LED on farms is still not particularly widespread.

‘The main delay in application is convincing growers that LED is an economically sensible move,’ Davis said.

‘This is because LED is more expensive that the lighting technology that is currently used on farms. When the price starts to drop there will be a lot of growers looking to invest in the technology.’

One of the main reasons for this is the fact that LEDs are constantly advancing at such a speed that prices of lighting units are remaining similar to what they were two years ago. Installation costs are falling, but the price of LED does still not appeal to many growers.

LED spectra can be adjusted to control many aspects of plant quality including appearance, height and flowering time.

The advantages of LED are considerable, as well as altering the light spectrum, the low temperature of LED means that they can be placed near to the plants without damaging them. There are also no heavy metals or glass in LEDs, whereas sodium lights do sometimes break leading to contamination.

But the main advantage of LED farming is that it is impregnable to global warming, which means plants can be cultivated without interruption, no matter what the weather.

‘The systems that we are talking about are never going to replace field crops,’ Davis says. ‘What we are going to do is add another layer of crop production into the current system, that is robust enough to survive climate change and adds security to the food chain. These systems will produce the same quality of crops all the time, without being dependent on weather.’

Since joining Stockbridge from academia, nearly half a decade ago, Davis has been really surprised by the interest that both the farming and the lighting industry has shown in his work.

He has been particularly impressed by the farming industry’s desire to bring academic science into practice, however he has been unsettled by the barriers that are in place to prevent this progress.

‘We need lower costs for LED farming to take off,’ Davis concluded. ‘But not at the expense of quality. Prices are coming down, but we need to be in a position where people look at the technology and say yes, this makes obvious economic sense.’
