Networked lighting control, the second revolution within the lighting sector, guarantees cost savings, and improved environmental conditions in new structures and renovated buildings alike. during a recent study, supported the detection of electricity consumption in 100 contexts, the planning Lights Consortium (DLC) found that networked lighting control systems can yield savings on the brink of 50% in an installation’s electricity use. Wireless network technology, for instance, results in a discount in wiring with a consequent decrease in installation and maintenance costs, combined with the likelihood of remotely controlling and programming the brightness of various light points.
The pairing of LED lighting, the primary lightning revolution, with wired or wireless network communication has allowed the creation of intelligent lighting control systems that integrate sensors, advanced information science, and connectivity. LEDs require relatively simple control circuits, don’t lose efficiency even at low brightness, and withstand an outsized number of on/off switching cycles. additionally to adjusting the sunshine intensity, LED dimming lets occupants and building managers dynamically vary the gradation of sunshine so as to satisfy different lighting needs.
The main functionality of a lighting system is to supply an area with the quantity and quality of illumination appropriate for the precise context while minimizing energy consumption. Lighting control strategies that sense and answer the presence of occupants and adjust the output of artificial lighting as daylight conditions change can substantially reduce electricity use compared with traditional lighting systems.
Networked lighting systems enable advanced features like presence detection, flexible programming, networking to the remote system, daylight adaptability, and real-time monitoring. These features help building operators reduce maintenance costs and increase the efficiency of their structures, improve the ambient environment for occupants, and exploit the new capabilities of IoT infrastructure.
Networked lighting combines LED technology with intelligent control systems capable of maximizing energy savings through flexible and dynamic programming of sunshine points divided into zones, remote of operations via apps, measurement, and monitoring in real-time. Features like high data-processing capacity, wireless connectivity, and therefore the possibility of putting in additional sensors within the LED light points allow the deployment of networked lighting systems suitable for supporting the building internet of things (B-IoT).
Components of a networked lighting system
A networked lighting system is formed from dimmable drivers, ballasts, intelligent light and temperature sensors, manual switches, power supplies, and every one of the hardware and software components necessary to perform the control, configuration, and programming of the system, including storage of server or cloud information. Sensors and control systems are connected via a wired or wireless connection to make a network during which the addressable devices are often configured and programmed individually or grouped into zones.
Depending on the degree of complexity, the system is often confined to one device or to an area, a building, or a whole populated area. As for the individual devices, some manufacturers offer solutions consisting of an LED driver which will be controlled remotely (via app and Wi-Fi network or by means of a special remote control) and sensors integrated within the same device.
In terms of performance and benefits, whole-building lighting control systems are the foremost efficient solutions. they allow accurate multilevel control strategies, collecting consumption data for subsequent processing and analysis. This data is especially useful in supporting maintenance activities. Although the whole-building solution is technically complex, it offers the simplest potential to scale back energy consumption and supply the best possible lighting conditions for occupants.
Networked lighting solutions
Among available networked lighting solutions that buyers can choose between is Osram’s LIGHTIFY solution. this is often an innovative and intelligent lighting system with wireless functionality. Operators and occupants can use a smartphone or tablet to program LIGHTIFY ceiling lights also as lamps, switches, pushbutton couplers, sensors, or entire LIGHTIFY systems via the network. As shown in Figure 1, the wireless interface employed by the devices is predicated on the Zigbee standard, and therefore the control systems hook up with them via a gateway.

Zigbee may be a standard for wireless data transmission developed specifically to manage short messages, like those required by smart-home and smart-building applications. Zigbee technology ensures low energy consumption and high system longevity without maintenance. LIGHTIFY Pro targets professional applications with installations of up to 100 light points, like offices. the house version is for domestic applications with up to 50 light points.
Philips also offers solutions for both the house and professional sectors. Its wide portfolio of products for lighting control ranges from simple wall dimmers to intelligent sensors and therefore the most advanced management and lighting control software. The Philips Dynalite series is among the foremost widely deployed, with thousands of installations worldwide. It includes an entire set of lighting control devices and is out there during a wireless version, supported the Zigbee protocol that gives all the advantages of an intelligent system, without the necessity for extra wiring.
Figure 2 shows an entire remotely controllable sensor within the Dynalite series. Dynalite sensors combine motion detection, light-level detection, and IR reception during a single unit controlled by a microcontroller.

Lutron Electronics, another manufacturer in lighting control systems, offers products starting from dimmers and switches to turnkey solutions for managing entire buildings. The Lutron LCP128 lighting system integrates the control of all lighting circuits, both on/off and dimmable and both internal and external, during a single, simple OS. The circuits are often activated automatically supported daily programs or manually through intuitive wall devices.
The LCP128 system is right for little business installations like restaurants, shops, spas, and recreation centers.
Network lighting advantages are often summarized as follows:
Reduction of electricity consumption and costs related to lighting systems
All companies consider minimizing costs so as to maximize profits. A lighting system can curtail costs by ensuring that the right sort of lighting is deployed and activated where and when it’s required. Lighting costs can account for up to half a building’s total costs for electricity consumption. By using programmable timers, motion sensors (which are capable of detecting when occupants enter or leave a room), and brightness sensors (which balance artificially produced a light with daylight), it’s possible to scale backlighting costs drastically.
Remote monitoring of devices connected to the network lets the system automatically send alarm notifications via email or SMS when problems arise. it’s also possible to supply daily reports indicating which devices require maintenance or replacement.
