Smart City Street Lights Sensors

The smart street lighting system addresses the issue of excessive lighting by autonomously adjusting the brightness of luminaires based on the presence of pedestrians and vehicles. Unlike systems that operate at full power throughout the night, smart lighting implements context-dependent control, leading to reduced energy consumption and lower carbon emissions.

Ultra-compact QULON Mini controls and diagnoses street lighting. Wired, installs on cabinets or luminaires.

The intelligent lighting infrastructure provides comprehensive control: from remote management and real-time monitoring of luminaire status to advanced analytics and preventive maintenance. This is achieved through high-performance control modules, gateways that ensure reliable data transmission, and multifunctional software. Sensors complement the system, making it dynamic and adaptive to environmental changes.

Perception Layer for the Smart City

Sensors are compact, high-performance devices designed to analyze changes in the environment. Modern sensors are characterized by high accuracy [1], broad compatibility, and robust construction, engineered for seamless, uninterrupted operation. Among our offerings:

  • Wire Daylight Sensor, which measures the level of natural light. Essentially, this is the first step for systems aiming to move away from adjusting lamp states based on time or intervals (timer and time relay). The daylight sensor allows for smooth brightness adjustment and improved visibility on cloudy days, as well as energy savings on clear days by turning on the lights later.
  • Smart Microwave Motion Sensor continuously emits low-frequency microwave waves and measures the reflected signal. By detecting vehicle movement, it triggers the activation or increase in lighting brightness.
  • Smart Infrared Motion Sensor captures infrared radiation emitted by humans or animals, enabling "lighting on demand."
  • IR Temperature Sensor is designed for precise traffic analysis, allowing the identification of off-peak hours and areas with no presence or movement at night, thereby reducing energy consumption and light pollution.
  • Luminance Sensor, by measuring light levels at tunnel entrances and exits, enables the system to smoothly adjust brightness and color temperature, preventing drivers from being blinded by sudden light changes and enhancing driving safety.
  • Meteo Sensor is integrated to monitor factors (heavy rainfall, fog) that reduce visibility, thus requiring the activation or increase of lighting brightness. Upon detecting hazardous conditions, such as storm winds, an alert sent to the control room can contribute to enhancing urban safety.

Qulon sensors support remote configuration and updates, providing management flexibility. Devices with a Zhaga connector allow for "hot" swapping, minimizing downtime. All devices have IP65/IP66-rated enclosures and operate reliably in a wide temperature range from -40 to +70°C, ensuring durability in any external conditions. Comprehensive support, including a 36-month warranty and access to updates, makes maintenance and operation straightforward and hassle-free.

Intelligent Lighting Architecture

The intelligent architecture integrates multiple elements for comprehensive urban lighting management. It enables remote control over individual street sections, video processing for classifying vehicle and pedestrian movement, as well as energy consumption analysis and detection of unauthorized connections. Coupled with this, fine-tuning the brightness of each luminaire significantly reduces energy consumption without compromising safety during nighttime movement.

The most effective solution lies in maintaining luminaire brightness at the minimum necessary level that complies with national and regional safety standards. Data from sensors is continuously collected and analyzed to adjust lighting in real-time. As soon as the controller receives a signal within the specified range, it performs the necessary actions (turning on, dimming, turning off). This adaptive approach can achieve energy savings of up to 85%.

Smart City Based on Lighting

The Internet of Things (IoT) infrastructure, where each lamppost is a network element, closely links smart lighting with the broader concept of the "smart city." This intelligent foundation serves as the basis for a large-scale technological architecture that analyzes data and provides value-added services [2]. Such an approach enables the implementation of a cost-effective and environmentally sustainable urban management model.
