Smart Street Lighting Introduction

For a better understanding the architecture of the smart roadway & street lighting, how it working, and how it make a safer, more attractive, and sustainable smarter city? Everything you need to know about the Smart Street Lighting

 

 

Smart street light is the public lighting fixtures that incorporate technology of cameras, ambient sensor and the motion sensor network for real-time controlling and monitoring - to achieve adaptive lighting which realizes the maximum energy optimization by automatically dimming by surroundings intensity brightness or the movement of the vehicles/pedestrians and auto-dimming by the programmed schedules.

 

Most of the municipalities are still using outdated traditional high pressure sodium lamps which are inefficient street lighting facilities and double energy bill cost than the LED street luminaries. Moreover, the operating and maintenance cost and lighting pollution will be multiple times of intelligent street lighting.

 

By 2025, with over 0.35 billions of streetlights globally, we can reduce carbon dioxide(CO2) emissions significantly by update the old HPS lamp to LED street lights, the result will be amazing even if half of them done in the next decade, esp. With smart dimming lighting fixtures, maximum energy saving up to 85%, and shorten the payback time for the investors with up to 30%.

 

 

Key Features of the System

 

 

 

How does the SMART LED STREET LIGHTING WORK?

Power Line Communication (PLC) technology operates as follows:

The input side of lighting system shall be equipped with a PLC transmitter-controller, and its output side, i.e. the lamps themselves — shall be equipped with appropriate receivers. Normally, luminaires are equipped with traditional dimmable devices with a 1-10 V interface. PLC allows establishing communication between control element and dimmable lamp without installation of additional network for data exchange. Each luminaire has its own ID number. The system maintains its operability, while the operator can regulate lighting intensity of separate group of luminaires, as well as of one single lamp within certain interval ranges. For example, the system may increase lighting intensity during cultural events performed in a separate part of a city or town during nighttime. As an example, provide additional local lighting for cultural events in a separate part of a city or town in the evening.

 

 

Pattern of operation and lighting level adjustment by using of intelligent lighting system.

 

Green zone indicates level of energy savings by using of intelligent lighting system (correlation 60% ~ 40% ).

Time of astronomical sunset/sunrise based on 21st of March — the spring equinox. This is an average indicator for the calendar year. Consequently, data is prepared for Almaty city. In case if system operates in another city, the system will automatically reset according to geographical coordinates of operation region.

 

Thus, the system not merely allows to efficiently save the electricity, but also factors in the specificity of lighting depending on the time of the day, weather conditions or features of the illuminated space.
