Beyond Energy Efficiency: Lighting as A Path to the Industrial IoT

Luca Ragaglia, Digital Lumens, USA

LED lighting retrofits have long provided a means to new savings for industrial companies. By replacing legacy lighting with LEDs, facilities have been able to realize upwards of 40% savings in lighting-related energy costs. Intelligent luminaires, which include occupancy sensing and local controls, can further increase that savings.

However, today’s competitive industrial landscape demands more- the good news for many facility managers, supply chain and operations leaders, and manufacturing executives is that the same intelligent LED network that can deliver up to 90% in energy savings and paybacks of less than three years can also pave the way for new, sensor-based solutions that create new opportunities to monitor and optimize operations.

Through intelligent lighting, and its uniquely qualified ability to create a constantly powered, easily connected, and perfectly spaced network, industrial spaces of all stripes can be instrumented for the Industrial IoT (IIoT). Beyond lighting based-energy efficiencies, this instrumentation enables innovative solutions sourced from both in-light and off-light smart sensors that monitor devices and usage, activity and occupancy, and environmental conditions, then feed that data to a centralized platform (or platforms) for analysis and review.

With the resulting data, stakeholders can exercise greater and more granular control over their facilities, create a logical representation or digital twin of the physical plant, and leverage new, data-based insights to create both quantitative and qualitative value streams across oft-neglected spaces between process cells.

Our presentation will detail, through real-life customer use cases, how forward-thinking industrial leaders can leverage common energy efficiency and sustainability initiatives into lighting-based IIoT solutions that create exponential value and unique competitive advantages.

Human Centric Lighting – A Practical Approach

Johannes Seifermann, Regent, Switzerland

It is no longer a secret that light has a great influence on our mood and understanding better and better which factors must be considered in Human-Centric Lighting planning (HCL).

Therefore, it’s not surprising at all that after initial positive experiences in retirement homes and assisted living facilities, the "Office & Education" application is also very much in line with this topic, as free-standing luminaires are excellently suited for a customizable lighting solution.

But what does it mean for the product itself? What are the new requirements a HCL luminaire should fulfil? A translation from new specifications into a product.

Protection of Luminaires Against the Overvoltages Effects: Coordination Between External and Internal Defensive Means

Matteo Gavazzeni, GEWISS, Italy

The world of luminaires is living a season of big renovation due to the introduction, gradual but irresistible, of the LED base technology.

This evolution is bringing many undeniable advantages like longer products lifetime, higher level of energy efficiency but, at the same time, it exposes the products even to new and unpredictable technological challenges.

One of this issue is represented by the overvoltages that might occur in the network due to operation switching in the part of the upstream installation supplying the luminaires and, even more, that could be caused by the extremely high-energy stresses produced by the lightning strokes.

This type of problems, although normally connected to outdoor installations, could also be detected in case of indoor applications, particularly when unusual and special current using equipment operate in the same area.

This presentation brings a general overview about the main problems that those phenomenon could cause to the products if they are not properly protected by construction or by external protective means.

As a first point, the presentation will provide a proper classification of the different overvoltage types (common and differential modes) and the main test methods used to simulate their effects.

It will proceed by introducing some technological measures to make the luminaires able to ensure a proper level of protection

The focus will be then moved to the external installation and, in particular, to the way to ensure a proper coordination between the protective devices installed outside and the level of protection offered by the luminaires.

A discrimination between different protection solutions will be propose according to the following two main parameters: the type of connection to earth adopted by installation (TT, TN or IT) and the classification of the luminaires in accordance with the protection against the electrical shock (class I or class II).

Indeed different approaches to protect products may be adopted in accordance with the two above-mentioned conditions and therefore, the last part of the presentation will be devoted to define the best ways to manage these different scenarios.
