The perfect solution for intelligent public lighting control

The perfect solution for intelligent public lighting control

1. Introduction:

After the success of ourwhite paper on Casambi-Adquio integrations Indoors, we now focus on outdoor installations, specifically public lighting. We highlight the particularities of this environment and how the combination of Casambi and Adquio provides advanced and efficient solutions.

2. Choice of Luminaires:

The decision on what type of luminaires to select for public lighting installations is a critical step that directly affects the effectiveness of the system. In this context, two clearly differentiated options are presented: those that already incorporate Casambi integrated from their manufacturing and those that allow the subsequent integration of this technology. Both alternatives offer different advantages and, therefore, the choice depends on specific factors of each project.

Luminaires that have factory-integrated Casambi stand out for their simplicity of installation and configuration. This “out of the box” approach simplifies the process as these luminaires are equipped with the necessary hardware and are ready to connect to the Casambi network without the need for additional modifications. This type of solution is especially effective in projects that seek a quick and hassle-free implementation.

On the other hand, luminaires that do not include Casambi as standard, but allow for later integration, provide additional flexibility. This approach is ideal for projects updating or improving existing systems. The ability to add Casambi to already installed luminaires extends the useful life of the latter and facilitates the transition to a more advanced management system.

Both options allow remote management of the luminaires, offering full control over intensity and on and off. This versatility contributes to energy efficiency and the ability to adapt to the specific needs of each public lighting project.

3. Casambi Communications Chips:

Within the technological heart of the Casambi integration are the communications chips, the base component, that allow wireless connectivity and intelligent management of the luminaires. Casambi offers two different versions of these chips: the ‘traditional’ nRF52832 and the ‘Long Range’ nRF52840. These chips, manufactured by Nordic Semiconductor, are essential to boost Casambi’s capabilities in public lighting environments.

‘Traditional’ chips have been widely used and tested in various Casambi applications. They provide robust and reliable connectivity, allowing efficient communication between the luminaires and the Casambi network. However, technological evolution has introduced ‘Long Range’ chips, an advanced option that offers even greater range and optimized performance. The latter have been designed to face specific challenges of outdoor installations, offering an ideal solution for public lighting networks.

The integration of these chips is materialized in the CAS-24V-ZHAGA-4P-80-DA device, developed and distributed by OLFER in Spain. This device, created for easy integration, stands out for its resistance to ultraviolet radiation, its IP66 rating that guarantees protection against adverse weather conditions, and its ZHAGA Book 18 connector, which facilitates the standardized connection of components.

The latest version of the ‘Long Range’ chips has demonstrated a proven range of over 200 meters between direct-view nodes. This achievement is crucial in the context of public lighting, where the separation between luminaires rarely exceeds 200 meters. Additionally, the mesh feature of Casambi nodes, where each node functions as a repeater, ensures efficient transmission of messages between luminaires, even in dense urban settings.

4. Public Lighting with Casambi:

The application of Casambi in public lighting environments represents a significant milestone in advanced lighting management. The distinctive characteristic of Casambi networks, the ability to operate in a mesh topology, is revealed as a relevant factor in the efficiency and reliability of these systems in public lighting contexts.

In the specific environment of public lighting, where the separation between luminaires rarely exceeds 200 meters, the connectivity of Casambi nodes, with its mesh feature, is a perfect fit. Each luminaire functions as a node, and the ability to efficiently transmit messages over the network means that, even in individual failure situations, communication between luminaires remains intact. This redundant design guarantees operational continuity, essential for the safety and efficiency of public lighting installations.

It is important to note that, in the event that a luminaire fails, the Casambi controller continues to perform its function, and the network persists in its operation. The resilience demonstrated in these circumstances positions Casambi as an ideal management system for public lighting, providing exceptional security and reliability in the management of complete lighting networks.

The limited separation between luminaires, combined with the mesh capacity of the Casambi nodes, means that any message on the network can reach all luminaires with a range greater than 200 meters. This synergy between network architecture and communications chip capabilities ensures consistency in control and management, regardless of geographic distribution or environmental conditions.

This redundancy and robustness are key elements in the application of Casambi in public lighting, where operational continuity and efficient management are imperative.

5. Start-up:

The implementation of Casambi luminaires in outdoor installations presents fundamental similarities with the process used in indoor environments, but with specific considerations to adapt to the public lighting context. Once the luminaires have been physically installed and powered, the setup process is simplified through the Casambi app, which allows complete control of an entire street or common lighting area via a tablet.

It is important to remember that, in a Casambi network, the maximum limit is 250 devices, while in ‘Long Range’ networks like these, this limit is reduced to 60 devices. This distinction is essential due to the slower communication speed in ‘Long Range’ networks, which could lead to faster saturation, especially when using devices that constantly send information, such as presence/luminosity detectors or D4I devices. However, this limit can be easily overcome by implementing Adquio controllers, which allow multiple Casambi networks to be joined together as needed.

To centrally connect and control the network of Casambi outdoor luminaires, it is simply required to install an Adquio device with an internet connection and a Lithernet gateway near the luminaires. These devices are housed within watertight boxes to ensure protection against adverse weather conditions.

The implementation of these controllers allows all information from a group of luminaires to be transmitted efficiently to the SCADA control system.

This control center, being managed by a controller, gives you the freedom to program any type of action on your luminaires. Simultaneously, it provides a secure connection to the control center where you are using your Adquio SCADA Cloud.

7. Centralized Control with Adquio:

The centralized management of the Casambi luminaire networks becomes a reality through the strategic implementation of Adquio controllers. These devices not only serve as an essential link between luminaires distributed in the field, but also play a critical role in the efficient collection and transmission of collected data.

In the control part closest to the luminaires, we find the elements that we have just seen. These components, meticulously selected and located within watertight boxes, make up a robust system that guarantees protection against adverse weather conditions, ensuring the integrity and continuous operability of the control system.

Let’s imagine a scenario in which the luminaires respond instantly to the presence of people, adjusting their light intensity to adapt to the need of the moment. When activity decreases, the luminaires automatically dim their brightness, ensuring adequate lighting without wasting unnecessary energy. This smart approach not only reduces long-term operating costs, but also contributes to resource conservation, reduced nighttime lighting pollution, and reduced carbon footprint.
