Power over Ethernet (PoE) lighting is an innovative and fascinating technology that has revolutionized the way we light our buildings. Unlike traditional lighting systems that rely on separate electrical cables, PoE lighting utilizes the existing Ethernet infrastructure to deliver both power and data to lighting fixtures. This integration of power and data transmission not only simplifies installation and maintenance, but also opens up a world of possibilities for smart and energy-efficient lighting.
One of the most compelling aspects of PoE lighting is its simplicity and flexibility. It allows for easy installation of lighting fixtures without the need for specialized electrical wiring. Instead, low-voltage power is delivered via standard Ethernet cables, making the installation process more straightforward and cost-effective. This streamlined approach is especially valuable when retrofitting modern lighting in older buildings.
PoE lighting systems are also highly customizable and offer the ability to remotely control and monitor each individual light fixture. With the integration of smart lighting controls, users can adjust the brightness, color temperature and even the color of the light to suit their specific needs. This level of control not only increases user comfort, but also contributes to energy savings as lights can be automatically dimmed or turned off in unattended areas.
Energy savings with PoE lighting
Energy efficiency is a key benefit of PoE lighting. By enabling granular control of light fixtures, PoE systems help reduce energy consumption and lower operating costs. Sensors, such as occupancy detectors and daylight sensors, can be easily integrated into the system, further optimizing energy consumption by ensuring that lighting fixtures are only on when and where they are needed. These features make PoE lighting an environmentally friendly solution that aligns with sustainability goals and energy efficiency standards.
PoE integration with the internet
PoE lighting integrates seamlessly with the Internet of Things (IoT). This is done conveniently with a hub that connects to the lighting fixtures and is also connected to the internet. This provides a platform for building automation and data collection that opens the door to a wide range of applications, such as real-time occupancy tracking, space utilization analysis and predictive maintenance. PoE lighting systems can also integrate with other smart building technologies, improving overall building efficiency and occupant experience.
Installing PoE
In a smart PoE network, cables connect to an Ethernet switch port capable of delivering DC power directly to the LED lighting fixtures or to a "node" that distributes power and data to the lighting fixtures, sensors and controllers.
In larger installations, the LED luminaires are often a troffer. Depending on the PoE lighting system, the consumption in the port, troffer size and manufacturer, one node can serve one or two troffers, up to 7 lighting fixtures and optionally incorporate a data port to control the lighting (e.g. dimmer or a sensor). The node-centric solution requires fewer powered ports and less energy than a luminaire-centric solution.
The most common LED light fixture configurations are shown below. For all LED light fixture configurations, the maximum power is supported by each structured cable channel and node. This is typically 100W or for some outputs rarely exceeds 60W. This also means that PoE lighting is generally not suitable for large-scale lighting tasks, such as exterior lighting on masts.
Support for PoE lighting
With the right guidance and support, installing PoE is a simple exercise that most installers and electricians will be able to handle. At Lumega, we have taken courses in PoE lighting and will be able to help with the contact to the best manufacturers on the world market and at the same time supply these hardware components in a selection of our lighting fixtures, so the complete PoE lighting solution can be delivered. This ensures we deliver a complete solution together.
