System Lighting Management
KENON systems provide total flexibility through addressable control and monitoring of every luminaire in a building. Its lighting management systems optimise energy efficiency and sustainability, provide total flexibility through addressable control of luminaires, and combine comprehensive central management and monitoring of the installation with powerful local user control.
Energy efficiency is optimised through presence and absence detection, daylight-linked dimming and scheduled control, by maximising daylight through solar-shading and window blind control, as well as integrated control of other energy consuming devices including air-conditioning.
Systems incorporate the open technologies of Dali, Lon, Bacnet and IP for energy-efficient control of lighting as well as for seamless integration and interoperability with other services to achieve efficient and joined-up control of all energy-consuming devices.
KNEON systems combine hardware and software, provide total compliance with local Building Regulations and leading international green rating systems. Systems are available as fully designed and commissioned systems or in modular form for design and configuration by third-party integrators.
Digital Addressable Lighting Interface (DALI)
It offers a range of controllers capable of connecting DALI devices to the DyNet network, allowing full control of addressable lamps, addressable groups and broadcast groups, as well as relay-controlled power management (Green DALI) for increased energy savings. All DALI capabilities can be accessed and commissioning by site management software, enabling detailed reporting, diagnostics and emergency lighting controls for DALI systems. DALI distributes the control intelligence into each luminaire. This enables precise modular control when used in conjunction with appropriate DALI Gateway. The system also provides a MultiMaster controller that communicates to a single universe of DALI lighting drivers, sensors and User Interfaces.
Dali drivers are individually addressable and DALI load controllers can send unique instructions about switching and luminance to each lamp, zone or universe from a single instruction. Some controllers are fully bi-directional, enabling critical status information from each luminaire to be reported to the DyNet network. Circuit allocation and data wiring may be determined without reference to each other. The data cable is a non-polarized, two-core, mains-rated. Cable with a maximum network length of approximately 350 meters (1.5mm2 cable). During commissioning, up to 16 native DALI groups may be assigned. This information is stored in each DALI driver, as is the individual address, scene value and power on level. DyNet addressing can be used to create more groups, which are then mapped to specific DALI channels via the controller.
The BACnet gateway that allows communication between a building management system (BMS) using the BACnet protocol and lighting control system. This gateway between the two systems allows high-level communication, thereby opening up a number of integration opportunities. It allows the BMS to triger tasks and time based events in the lighting control system and enables the system to report back current system status.
The BACnet protocol uses addressable points for communication; these addressing points can be adjustyed by the BMS for triggering required function such as timed events or the Philips Dynalite system for reporting back current system status.
An example of the kinds of functions that can be achieved is when the BMS system enters "After hours" mode, a request can be sent to the lighting control system via the BACnet protocol to turn off all the lighting on a partcular floor. The lighting control system can then flash the lighting off, warning any occupant still on the floor that they need to interact their continuing operation of the area by pressing an "afterhour" button or the lighting control system could use passive presence detectors for detecting occupants. If no occupants have indicated their presence, then the lighting control system will switch off the lighting and report this back to the BMS so that the air-conditioni plant can also be automatically shut down.
LonWorks (also referred to as LON – Local Operating Network) is a networking platform created by Echelon Corporation for controlling the BMS and automating functions within buildings, such as lighting. The LONwork gateway supports preset control for 100 presets per area across up to 30 areas. Multiple gateways can be used together to accommodate larger or more complex lighting system networks.
PoE Connected Lighting
Connected lighting is part of the Internet of Things (IoT) trend. By building on the digital nature of LED technology, connected lighting brings illumination and IT together. With the help of PoE technology not only power and data can be delivered for the luminaire over a standard Ethernet cable but it also allows the lighting system to be merged with the IT system. Moreover, Philips PoE (power over ethernet) enabled luminaires also incorporate Visible Light Communication (VLC) technology wherein the PoE luminaires continuously transmit their IP address at higher frequency which in turn can be detected by a smartphone app allowing app based controllability and personalization of light.
In addition to illuminating office spaces with high quality and energy efficient LED lighting, connected lighting with POE can inform owners of maintenance requests, occupancy trends, temperature control, and more creating offices that are more efficient, sustainable, and responsive.
In a connected lighting system, every luminaire is directly connected to and uniquely identified within a building's IT network, allowing system managers to monitor, manage, and maintain individual light points via lighting management software.
With integrated sensors, connected luminaires become points of intelligence that share data on occupancy, activity patterns, and changes in temperature, humidity, and daylight levels, with wireless communications, connected luminaires can deliver location-based services and in-context information to people in illuminated spaces via mobile devices and apps.
Analog, 1-10 V
For 1-10V lighting control systems, the load controller transmits a low voltage linear direct currect (DC) signal. 1V equates to 1-5% (minimal) lighting output; 10 V equates to 100% output. All fittings on the same lighting group respond to the dimming instruction at the same time, There is no error checking in this method. As any voltage induced on the control line is considered a correct signal by the fittings, the lammp cannot turn off completey using the control line alone. A relay can be controlled in parallel with the control signal to turn offc the fittings completely.
DMX512 (also called DMX or Digital Multiplex) is a digital communication standard commonly used to control stage lighting and effects such as dimmers, fog machines and RGB lights. The use of DMX has also expanded into non-theatrical interior and architectural lighting. DMX employs unidirectional communication when connected.
DALI Emergency Reporting
DALI is the de facto industry standard for emergency lighting control and is fully catered for by the DALI controller range. The DALI emergency reporting feature in site Management software allows users to schedule system tests and report the status of emergency drivers that are present on the DALI network. This feature puts the emergency drivers into a self-testing mode to confirm they operate correctly on battery power.
Site Management Software allows users to:
•Manage emergency fixtures;
•Schedule or manually start emergency tests ;
•Generate emergency fixture test reports;
•Query emergency test results.
OPC (Open Productivity & Connectivity)
OPC refers to a collection of standards maintained by the OPC Foundation for open connectivity of industrial automation devices and systems. OPC standards are used in a variety of applications, including real-time data access, alarm and event monitoring, and historical data access. The lighting system supports the OPC Data Access and OPC Alarms & Events datasets for connection between OPC proxy server and compatible building management systems or OPC clients on the same network.
