At present, LED lights have more uses besides lighting. When combined with a low-voltage IP-based infrastructure that connects to intelligent networks, LED lighting becomes part of a powerful system network that works together to collect, analyze, manage, control, and respond to set targets and real-time sensor feedback. The resulting "smart building" is more comprehensive in terms of operational performance because it can dynamically respond to operational problems, thereby increasing efficiency while conserving power and cost.
How does integrated smart lighting work with other systems? What technology is needed to integrate the system and maximize benefits? This article will provide an in-depth discussion on connecting smart lighting and infrastructure technologies.
Intelligent LED lighting network
The basic premise of connecting a smart LED network is that the lighting control is transferred from one centralized and relatively common way through most of the building space to another solution, which is aimed at the smaller, specific needs of the building. More importantly, because lighting is part of an intelligent network, it integrates (and can respond to) other components on the network. This applies in particular to commercial office buildings, medical facilities, warehouses, manufacturing and industrial facilities, and similar large or multi-purpose spaces where integrated methods are not feasible or inefficient.
Consider buildings that use automatic heating, ventilation, and air conditioning control (HVAC). HVAC monitors and adjusts the temperature to match the human body's comfort and machine performance, as well as optimal efficiency and cost. Connecting a smart LED lighting network will allow illumination to be synchronized with these same targets. This is accompanied by the response of the light to ambient temperature control. Therefore, connecting intelligent lighting networks will enable network users to increase productivity, positive emotions, concentration and happiness by adjusting lighting. It also has the potential to synchronize human physiological cycles to illuminate and enhance or reduce the amount of illumination required based on the amount of sunlight outside the window.
LED lighting and PoE
The key technology for intelligent LED lighting networks is Internet Powered (PoE), a low-voltage cable and device that connects the Internet of Things (IoT) to LED devices. PoE is simple because of the success of IP-based infrastructure platforms. By using PoE as the backbone of the LED lighting power and control system, the lighting is incorporated into the building as an IoT asset. In addition to the huge advantage of powering and providing data to a single-tier infrastructure, PoE costs less than copper cables. As shown in Figure 1, the PoE system architecture includes the following devices, which we discuss in the next section:
·PoE Gateway
·LED lighting equipment
·LED lights
·LED intelligent driver
·LED cable bundle
·sensor
·Wireless switch and dimmer
