CMS overview

LeafNut is a wireless control and monitoring system for outdoor and street lighting applications. The award winning solution provides users with the ability to make savings by reducing carbon emissions and lowering energy usage.

The system uses WiMAC protocol Central Management System (CMS) technology to remotely manage and control the output of individual lighting points, using a combination of GPRS and radio frequency.

Each lighting point can be dimmed using automatic profiles to match the specific requirements of the surrounding area throughout the night. At the users command, such as in the event of an emergency, lighting points can be brought back up to full brightness at the touch of a button, from either a computer, laptop, tablet or smartphone.

Every lighting point within the inventory is remotely monitored, with any faults being reported to the specified user(s) via scheduled email. Reports detailing the energy usage of each light, or a particular group of lights, are also available.

So far, LeafNut has been successfully installed by over 100 organisations across the world and is used to realise significant cost savings and reductions in carbon emissions.

Integration

Users receive scheduled reports by email and can integrate the LeafNut system directly with their current Asset Management System to keep a comprehensive inventory. Users will also receive training and support from the LeafNut Support team on any required aspect of the system.

Nodes

Each lantern has its own Node installed which can control either a WiMAC enabled ballast or driver, or any other conventional control gear for switching up to 400w or dimming through DALI and 1-10v Analogue protocol.Nodes available include: LeafNode, RetroNode, UniNode, MagNode and NemaNode.

BranchNode

This is the main control unit of the LeafNut system out in the field. It communicates bi-directionally through Radio Frequency with up to 256 Nodes, and through GPRS with the Trunk. The BranchNode contains a photocell and GPS locator, and has a typical urban range of 1km and a rural range of up to 8km where clear line of sight is available.

Trunk

The trunk is where users access and manage their LeafNut system. The LeafNut remote monitoring system can be managed wirelessly by laptop or desktop computer from anywhere in the world. It uses sophisticated ground-breaking WiMAC Central Management System (CMS) technology, which provides the operator with a secure Internet connection so nodes can be commissioned, assigned to a dimming profile and report back in a matter of minutes.

Energy consumption

Lowering carbon emissions by reducing energy consumption has become a major priority for Local Authorities with the introduction of the Carbon Reduction Commitment.

Most of the street lights in the UK are powered by an unmetered supply, which means that the energy consumption cannot be accurately metered. A feature of LeafNut is its ability to provide energy consumption data directly to the appointed meter administrator, as well as scheduled reports to the end user.

Monitoring and control

LeafNut cleverly allows street lighting engineers to securely monitor and control street lighting stock from anywhere in the world by using the internet. Management information is exchanged between the LeafNut enabled control gear and the central server, which means that users can identify: lamp problems in advance, on/off and end of life issues, predict lamp failure and create maintenance routines. There is a wide range of possible dimming and switching programmes available and no limit to the number of grouping configurations.

WiMAC protocol

LeafNut operates by using the WiMAC protocol and is fully compatible with other WiMAC based Central Management Systems (CMS), which enables the user to choose between vendors. This gives Local Authorities the freedom and flexibility to procure hardware from a number of sources and gives them the peace of mind that throughout the lifetime of the product, they have a number of support options.

Robust

The system has been developed by working closely with Local Authorities to understand their specific requirements, and has been rigourously tested in field trials to ensure it is robust. LeafNut is now widely deployed across the UK.

Scalability

Modular by design, LeafNut has been deployed in many places, from small car parks and highways, to mountain top villages and city wide installations, demonstrating that it is easily scalable.

The mapping tool, which is integrated with Google Maps, allows users to

easily view their entire lighting stock. This simplifies the process of plotting and managing installations as well as organising maintenance schedules. LeafNut also provides detailed and relevant report summaries to allow quick and easy viewing of filtered events. Time profiles have been enhanced to provide bespoke daily time profiles, allowing different schedules for festivity lighting, bank holidays and local events, which can be be planned up to a year in advance. This gives more flexibility and allows for more effective planning of lighting schedules.

Tools designed for simplicity

WiMAC, the Central Management System (CMS) protocol behind LeafNut, has developed a PDA tool to speed up and simplify the installation of

LeafNut. The PDA is a battery-operated handheld tool that allows engineers to automate the installation process. They can also manage, install and verify hardware on the system, meaning each column only needs to be visited once during installation, saving time and money.

Accessibility and control

Once installed users can continuously monitor their LeafNut system via a Mobile Android App to manage summaries and performance statistics.

BranchNodeThis is the main control unit of the LeafNut system out in the field. It communicates bi-directionally through Radio Frequency with up to 256 Nodes and through GPRS with the Trunk. The BranchNode contains a photocell and GPS locator, and has a typical urban range of 1km and a rural range of up to 8km where clear line of sight is available.

LeafNodeInstalled in a 20mm fitting, the LeafNode can offer full dimming and reporting capabilities for a luminaire when connected to a WiMAC enabled ballast or driver.

RetroNodeAs the NEMA socket variation of the LeafNode, the RetroNode can also offer full dimming and reporting capabilities for a luminaire when connected to a WiMAC enabled ballast or driver.

MagNodeUsed for switching any gear up to 400W, the MagNode does not have any dimming functionality but it is capable of basic fault reporting. It wires directly in to a ballast or driver with low powered variations also available for 2W-20W.

NemaNodeUsed for switching any gear up to 400W, the NemaNode does not have any dimming functionality but it is capable of basic fault reporting. It fits in to an existing NEMA socket with low powered variations also available for 2W-20W.

UniNodeUsed to control and dim through DALI or 0-10V and 1-10V Analogue ballasts and drivers. Using a 20mm fitting, the UniNode is wired directly in to the ballast or driver with basic fault reporting also available.

SensorNodeThe SensorNode is not capable of directly controlling a luminaire, instead the Node is wired to any sensor with a 0V Normally Open or Normally Closed connection. When the sensor is triggered, the Node relays a message to the BranchNode which then issues an “all on” command for a selected group of Nodes.

DALI Dimming – EN62386-207DALI drivers provide full DALI dimming support from 100% to 1% (depending on driver capability) and have the ability to switch completely off. Customers have the ability to control individual LED luminaires or specified groups. DALI also provides fault reporting on up to 64 devices of which 63 can be drivers with one controller.

1-10V/0-10V Analogue Dimming – EN60292 ANNEX EAnalogue 0-10V and 1-10V drivers provide linear dimming from a conventional 0-10V or 1-10V dimmer. Analogue drivers measure voltage at the control input to manage the intensity of the light, for example at 10V lights are on 100% and at 5V lights are on 50%. Analogue drivers can also be used for fixed output where customers need to reduce the output current to meet their needs. This is achieved by placing a resistor across the 1-10 input.

SmartNightWith programmable and pre-programmed drivers, lighting can be dimmed using pre-set levels, providing the customer with a reduction in power usage. The pre-programmed drivers can be dimmed to 50% or 75% for 6, 8 or 10 hours, and the programmable versions can be programmed with up to 8 unique dimming levels, down to 5% (depending on driver capability) from a PC and SmartNight programmer.

Charge Codes in the UKAn Unmetered Supply (UMS) is any electronic equipment that draws a current and is connected to the Distribution Network without a meter recording its actual energy consumption.

The Unmetered Supplies Operator (UMSO) provides the UMS service on behalf of a distributor, and the Unmetered Supplies User Group or UMSUG (part of the Elexon governing body) is an expert group that provides advice on specific UMS related matters.

Street lighting in the UK is unmetered, therefore any component that is to be used in street lighting must be submitted to Elexon for approval.Each component is tested to confirm the energy usage at different power factors.

Once a component has passed the tests and Elexon are satisfied, it will be awarded a unique charge code, also known as an UMSUG code.

A charge code is a 13 digit number assigned to apparatus that UMS customers, such as local authorities, use in their lighting inventory when submitting energy usage. Charge codes are used with an equivalent meter, such as LeafNut, to calculate volumes of electricity consumed in order to provide a more accurate energy bill for UMS.

LeafNut generates a daily report that calculates total energy usage over a 24-hour period (pseudo or equivalent metering). This is done through calculating switching times (recorded in the BranchNode) and dimming commands set in 7-day profiles. This report is automatically submitted to a Meter Administrator daily, who use the information to provide energy billing on behalf of a local authority.

TALQ is a global consortium initiated by companies from the lighting industry, with the aim of creating a globally accepted open standard for a management software interface for outdoor lighting networks.

TALQ was founded to accelerate the adoption of outdoor lighting networks, in order to provide energy savings and CO2 reduction, improved monitoring and maintenance, highly adaptive and programmable controls, and simplified data collection. The consortium also strives to enable system interoperability and avoid the perception of vendor lock-in.

The scope of the Consortium is:

• The TALQ Consortium will standardise the application protocol at the interface between the Central Management System (CMS) and Outdoor Lighting Networks (OLN)

• TALQ will deliver a software protocol specification for this interface that covers parameters and behaviour of end-points at the OLN and CMS side, needed for interoperability at application level

• TALQ shall not specify any physical aspect of the connection or connectivity

• TALQ shall not specify how to achieve the required illumination behaviour

• TALQ shall allow for vendor specific function or feature implementations of the local/segment controllers and management systems, fostering competition and differentiation of vendors

As one of the founding companies of the consortium, Harvard Engineering is keen to promote interoperability and simplified data collection, ensuring that users have a fully endorsed lighting controls solution.

The City Council previously had a traditional lighting stock with a 40 year replacement cycle and was looking for a solution that would reduce energy and carbon use and optimise its lighting service, improving service delivery. Westminster also wanted a control system which would allow engineers to effectively manage individual or groups of lights by specifically adapting light output at specific times to meet the environment individual requirements.

The success of the LeafNut installation by Westminster City Council has been significant in leading the way for other councils. LeafNut has now been installed by approaching 100 local authorities worldwide, including Zurs in Austria, Sydney in Australia, Hobart in Tasmania, and Blackpool in the UK.

With the installation of LeafNut, it is estimated that Westminster is saving a total of 1.5 million kg of carbon a year and approximately £420,000 per year - based on current energy prices. With energy prices only expected to increase, the installation is expected to save £20 million over the next 20 years.

In order to control the whole borough’s street lights, Westminster has installed over 100 BranchNodes, each managing upto 256 LeafNodes. Street lights can be reduced by 25% in areas where they used to burn brightly at off peak times, when there is little activity. Should an accident or emergency occur however, street lights can be brought back to full power at the touch of a button, using a computer, laptop, tablet or smartphone.

The City Council has adopted the principles of Ultra Efficient Lighting (UEL) “right light, in the right place, at the right time, controlled by the right systems” and adaptive lighting strategies will enable the lighting service to optimise its delivery realising energy/carbon and maintenance efficiencies.

Another benefit of LeafNut is the unique reporting feature which allows engineers to see the status and power usage of each street light. This allows maintenance schedules to be created and night scouting to be avoided, leading to further savings on maintenance costs.

Westminster - London, UK

As part of its ‘Smart Lights’ project, Westminster City Council trialled the innovative LeafNut monitoring and control system for street lighting back in 2008. The trial was so successful that LeafNut has now been rolled out across Westminster’s 15,000 street lights, in the first major scheme of its kind in the UK.

Key benefits

Rolled out across Westminster’s 15,000 street lights, with over 100 BranchNodes currently installed controlling the whole borough.The potential to reduce light output by 25% during off peak times where there is little activity.The ability to monitor and control Lighting from CCTV control centre or the Police reports. If levels are too low managers will be immediately alerted.Harvard’s engineers are constantly working alongside Westminster’s street lighting engineers to ensure smooth running of the system.The installation of LeafNut is expected to save Westminster City Council an estimated £20 million over an anticipated 20 year product life cycle.

“Harvard’s LeafNut system is enabling Westminster to transform the public lighting service. The City Council now has a dynamic, interactive lighting solution suitable for the requirements of one of the world’s most demanding city’s. A system that not only meets our current demands, but will be able to adapt to future challenges. The ‘end to end’ solution provided by LeafNut promotes a two way dialogue ensuring that our needs are met and any concerns are addressed directly, with their ongoing support that is seen as a significant benefit.”

Dave Franks, chief lighting engineer at Westminster City Council

LED Driver Features

Switchable

These allow users to be able to have one driver that can switch between two or more pre-determined current outputs, for use with similar light fittings with different power needs.

Resistive Programming

This involves placing a resistor between two terminal blocks, to set a lower output current as required by the application.

Auxiliary Fan Output

Auxiliary Fan output is available factory set to 5V or 12V output and can provide 1 or 2 watts of power depending on model.

Hot Plug

This is when an output over-current occurs, if the LED is turned on or plugged into an energized driver. Most of our drivers have built in protection to limit the over current and protect LEDs.

Negative Temperature Co-efficient (NTC)

Helping to prevent light engines from overheating this thermal protection component measures the temperature of the light engine, to detect overheating of its LEDs. If the light engine reaches a high temperature that could damage the LEDs, the NTC adjusts the current to a lower level until a more acceptable temperature is reached. If the light engine continues to overheat it will cut the current therefore switching off the light engine and protecting the LED’s until it cools down*.

In recent years, advancements in technology have brought new options to the street lighting arena. One solution already offered by Harvard Engineering is LeafNut, a central management system (CMS) that can wirelessly monitor and control street lights through integration with client AMS databases. LeafNut provides exceptional savings potential through the remote management of dimming profiles and fault finding designed to reduce the need for scouting activities. LED technology is another option that offers significant energy-savings, as well as an extended life-time over traditionally used light sources.

Harvard has now identified another solution for the budget-conscious buyer, with a short-term payback period and a 3-year warranty alongside.

The new RetroLED range delivers a retrofit LED solution for SOX lamps and boasts an impressive energy-saving compared with existing luminaires. The ease of installation and reduced costs thereafter also make this an ideal option for modernising old streetlights without changing the existing columns and lanterns.

David Hale, the Design Engineer from Blaenau Gwent County Borough Council, was one of the first to recognise the potential for RetroLED application and promptly installed

a trial scheme. David explains, “With the rising cost of energy, we as a Council have to continually find ways to reduce our energy consumption. While looking for options on how to save money, we came across Salix funding and started to compile a business case by which to apply. We approached a number of manufacturers to supply a gear tray and lamp that would go into a SOX fitting. We had some very positive solutions provided to us (one of them being a gear tray and a 36W PLL lamp), and with the information gathered, we applied for Salix funding for the replacement SOX gear trays. Having obtained a positive assessment, the funding was then granted.

After discussing the progress with Harvard Engineering, they proposed that they could have a possible alternative to the PLL gear tray, by developing a more advanced LED gear tray. Three weeks later Harvard returned with a sample of the product and we were so impressed with the results, we decided to make a start with a trial installation right away.”

Currently available in 35W and 55W replacement options, RetroLED uses a lantern-specific gear tray holding a rectangular light engine, powered through an integrated Harvard driver. Producing white light with a colour temperature of 4,000K and a colour rendering index of 80 –

SOX lamps are typically 1,800K.

The light output produced by a RetroLED is 1,700lm (35W) and 2,900lm (55W), with a circuit wattage of 14W for the 35W replacement (versus an average 65W for SOX) and 23W for the 55W replacement (versus an average 77W for SOX). With a maximum output power of 10W, the RetroLED is also much more efficient.

During the RetroLED trial installation on a semi-rural residential road, one electrician was timed at a staggering 3-minutes to completely retrofit one lantern, including removal of the old gear.

David also comments, “The trial has now been running for a few nights, and having visited the site before and after, I can confirm that the light produced by the RetroLED gear tray has surpassed my expectations. I have also taken photographs before and after the installations and distributed these throughout the Council for the members to evaluate – we are unanimous in opinion that this is an impressive alternative to our original proposal of PLL lighting.”

Blaenau Gwent - Wales, UK

Every local authority can relate to the pressure of tightening budgets and the increasing need to manage spend as economically as possible. The installation and maintenance of street lighting in a borough often calls for a big slice of this financial pie and as such requires a significant consideration when the time comes to upgrade.

“We originally planned to change 2444 units to 36W PLL trays, but we are now planning to install the RetroLED gear trays to complete the conversion of the SOX fittings – RetroLED gear trays will give the Council an extra 16% energy savings over the PLL gear trays.”
