Smart Lighting - Light provided by the network


Economic Efficiency

up to 80% energy savings

Smart Lighting – Light provided by the Network

There are many things which come from the network: information, music, photographs, texts, and maps. But light? Under the label "Smart Lighting", the euromicron subsidiary MICROSENS presents a digital lighting concept. According to this concept, both the power supply and lighting control are implemented by means of the IP data network. The result is extremely convenient and, above all, offers enormous saving potentials.

Efficient lighting from the network

The basic idea is as simple as it is evident: Even economical LED lamps could be still much more economical if they would only shine during the period of time and with the intensity as is actually required. Illuminated rooms, floors, or underground car parks where nobody is around are indeed an expensive and "burning" issue for many companies. This predicament can be solved by means of an intelligent concept: Smart Lighting – the name is self-explanatory.

The light goes on, the costs go down

The Smart Lighting concept is implemented by means of the connection of intelligent network and LED technology. Via the deployment of sensors and actuators, the lighting is always used precisely where it is required. Only at times where a person is in the room, only in places where the natural daylight does not provide sufficient illumination, and only as much light as is required to see clearly and comfortably. Experts prognosticate energy savings of up to 80 percent, which can be reached in total via intelligent lighting concepts.

More than lighting: intelligent facility management

The LED lamps are provided with power over the data cable via Power-over-Ethernet. Special Smart Lighting Controllers integrate the lighting completely into the network infrastructure. The lighting is controlled via decentralized switches which run small control programs. With the help of these apps it is not only possible to control Smart Lighting, but also to implement complex building automation applications over the network.

A super-ordinated software platform allows the user to configure and monitor all system components. Statistics as the basis for efficient room and resource management additionally provide valuable information on the allocation of rooms and energy consumption.

The innovative MICROSENS Smart Lighting solution. LED lights are supplied with power by means of PoE+ over a non-conforming cabling according to DIN EN 50173-6. Sensors next to the lights provide data on the brightness, temperature, and on the presence of persons in the room. The Smart Director

System Components

Modern LED lighting systems consist of just a few components: the lamp with the LED light source, a smart lighting controller for communication and integration of lamps and sensors in the IP network, a sensor to measure the environmental parameters, a smart engine to supply lamps with power via PoE+, a network switch as the intelligent control center for the lighting system, and an app on the switch as a mini program to provide the necessary functionalities.

Smart Engine

The smart engine takes care of the energy supply to the lamps with Power-over-Ethernet Plus. It uses suitable, standard data lines, as are also used for the IT infrastructure.

The smart engine can be accommodated in a data processing cabinet or electrical control box, but also directly decentralized, e.g. installed in a suspended ceiling.
The number of engines is determined by the scopeand expansion of the lighting system.


Sensors close to the lamps measure the environmental parameters. Presence detectors identify whether persons are present in the room. Often a brightness and a temperature sensor are also integrated in the detector housing. Such combination sensors reduce installation costs as compared with the use of individual sensors and make data available for other systems, such as heating and air conditioning. When no one is in the room, the light switches off automatically and the heating or air conditioning is kept in the reduced standby mode.

Within the scope of the smart office concept, sensors from other completely separate systems can be integrated using a gateway (e.g. Homematic, EnOcean, KNX, IP500 etc.).

Smart Lighting Controller

The Smart Lighting Controller represents the link between the LED lamp and the IP network and manages the data traffic between the network and sensors/lamps.It is usually integrated in the lamps, but may also be mounted as a separate assembly near the lamp.

Network Switch

Because of their high computing power, network switches have long since developed from purely forwarding data packets to become intelligent control centers in networks. Based on a robust Linux operating system, they undertake additional tasks, such as controlling the LED lamps.

Applications (Apps)

Autonomous software modules or apps on the switches provide wide-ranging functionalities. The Smart Director app, for example, takes the entries from the user's smartphone or tablet and forwards the corresponding control commands to the particular smart lighting controller of the lamps. Configuration and management of the lamps takes place without any complex, expensive software package.

Installation and execution of the apps requires absolutely no intervention in the switch firmware. It remains unchanged, which significantly reduces the administrative workload. Several apps can run simultaneously on a switch thus offering a wealth of different functionalities.
