KNX DALI lighting control
In terms of the smart technology which can be introduced to buildings it is widely known that lighting systems gain the greatest level of efficiency. Standard lights are somewhat notorious for being a considerable drain on resources, with the cost and maintenance requirements affecting budgets for every building. Being able to take advantage of the benefits which home automation can deliver requires having the best system possible in place. This is exactly what the KNX DALI Lighting Control Interface delivers.
DALI, the Digitally Addressable Lighting Interface, is the accepted international standard for smart technology in light systems. The system was devised through an unprecedented level of co-operation across manufacturers around the world in order to ensure universal usage across different devices. What this means for smart building systems is that all compliant products can be connected to one network, allowing for centralised control.
Accessing the benefits of a DALI network for building lighting depends on using an interface which makes full use of the capabilities on offer. This is achieved through the use of a KNX communication stack interface.
KNX is the open source based network communication protocol specifically designed for smart buildings and building automation systems. Using KNX for light control has two advantages. The system is adaptive enough to allow for the full spectrum of smart controls to be implemented across the network, which means all beneficial aspects of lighting are made available. Secondly, and importantly, KNX commands can be sent through a range of means. In terms of lights, the control protocols can be transmitted either via powerline networking, twisted pair wiring or through Ethernet.
The ability to offer the most efficient smart lighting system possible is matched by the extent to which it can be used. There are, in practical terms, no limitations with respect to the amount of units which can be added to the KNX DALI Lighting Control system or to the automated control functionality. The best example of this in action in the world right now is Terminal 5 of Heathrow, where some 130,000 light fittings and motion sensors are controlled centrally through a KNX DALI system.
These controls can make a smart building system smarter. By making use of the combined interface you have the benefit of a system designed to give you the best service in the present day and have the confidence of knowing it will be able to meet all future requirements too.
