Two-step control system selection for street lighting

In this configuration, street lights are organized into groups and controlled by a central circuit breaker located in the streetlight electrical cabinet. The operation of the lights is triggered by photo relays or timers. During daylight hours, the power to the luminaire power lines is disconnected. This type of topology is commonly found in continental Europe and Asia.

In this arrangement, each lamp is individually controlled by an independent photo relay. Unlike the previous topology, in this case, the luminaire power lines remain energized during the daytime. This type of topology is commonly observed in countries such as the USA, UK, Canada, and other Commonwealth nations.

This economical control method involves the grouping of luminaires and centralized management from a single control cabinet. It is suitable for regions where a segmented topology is implemented for street lighting control. This method is compatible with various luminaire types and offers a straightforward installation process. However, it may not deliver the highest level of energy savings and individual monitoring capabilities for each luminaire's status.

This control method utilizes luminaire grouping and centralized management from a single control cabinet. It is applicable in regions where a segmented topology is implemented for street lighting control. Additionally, it enables group dimming of the luminaires from the central cabinet. However, it is important to note that this method is specifically designed for high-pressure sodium luminaires with electromagnetic ballasts. While it promotes energy savings, it does not provide individual control of each luminaire's status.

In open terrains without obstructions, an optimal choice for independent topologies is a radio system. Our solution is based on the LiTouch open protocol, operating on the reliable 868/915 MHz frequencies to ensure a stable and long-range connection. This versatile method caters to both dimmable high-pressure sodium lamps and dimmable LED luminaires, supporting NEMA and Zhaga connectors. It not only achieves maximum energy savings but also enables individual control of each luminaire's status. Nonetheless, it is essential to take into account the unique characteristics of the landscape during the installation process.

A solution based on GSM networks is well-suited for densely populated areas, mountainous regions, and locations where the use of radio channels is legally prohibited. It utilizes the existing GSM network infrastructure. This method is compatible with both dimmable high-pressure sodium lamps and dimmable LED luminaires, supporting NEMA and Zhaga connectors. It facilitates significant energy savings and enables individual control of each luminaire's status. However, it's important to consider the cost of cellular communication tariffs and the coverage area provided by mobile operators when implementing this approach.

A solution based on LoRa networks is ideal for densely populated urban areas, mountainous regions, and areas where a well-established LoRa network infrastructure is available. By utilizing the existing LoRa network infrastructure, this method offers efficient and effective control over street lighting. It is compatible with both dimmable high-pressure sodium lamps and dimmable LED luminaires, accommodating NEMA and Zhaga connectors. This solution enables significant energy savings and provides the ability to individually control and monitor the status of each luminaire. However, it is crucial to consider the associated costs of LoRa operator tariffs and the coverage area provided by the LoRa network when implementing this approach.

This approach is particularly well-suited for urban areas characterized by high population density, towering buildings, and challenging terrains. It is an ideal choice when a segmented topology is implemented for controlling street lighting in your region. Moreover, it offers significant advantages for installations along highways and expressways. This method is compatible with both dimmable high-pressure sodium lamps and dimmable LED luminaires, regardless of whether they have NEMA connectors. By enabling individual control over each luminaire's status, it ensures optimal energy efficiency and maximizes power savings. However, it is crucial to consider the unique challenges that may arise during the implementation of this method in locations with intricate power topologies.

This method utilizes a combination of Wireless LiTouch system technology and various motion sensors. It enables the highest level of energy efficiency and is particularly well-suited for implementation in parks, squares, and low-traffic roads. It is compatible with both dimmable high-pressure sodium lamps and dimmable LED luminaires, supporting NEMA and Zhaga connectors. However, it should be noted that this method requires a relatively complex installation process.

This method is employed for managing LED luminaires powered by solar batteries. It is utilized in areas lacking centralized electricity supply and is particularly suitable for illuminating pedestrian crossings and objects situated in remote locations. This comprehensive solution comprises a specialized luminaire, solar battery, solar controller, and battery. It is specifically designed to be compatible with specialized LED luminaires. Operating through GSM networks, it allows for individual control of the luminaire's status and battery charge.
