Smart Street Light Solution

Situation analysis-Industry background

According to data, urban street lighting accounts for about 30% of the national lighting. In 2017, China's total power generation was 3255.9 billion kilowatt hours, of which 13%, or 423.3 billion kilowatt hours, were used for lighting. Of this, 30% was used for outdoor lighting, about 130 billion kilowatt hours. Moreover, the electricity consumption of urban road lighting alone exceeds that of outdoor lighting by more than 50%. With the rapid development of urban construction in China, the energy consumption of urban street lights is also increasing rapidly year by year. However, street lighting is mainly inefficient lighting, and the energy utilization rate is less than 65%. There is serious energy waste, and there is great potential for energy conservation. It is imperative to save energy in urban street lighting.

customer pain points

The main drawback of street lamps now is that they operate at overload in the second half of the night, causing increased fluctuations in line voltage. In some places, it even exceeds about 15% of the rated voltage. Especially in the second half of the night, commercial and civilian electricity use no longer works, and the reduction in electricity load causes the phase voltage of the power grid to sometimes approach 245V. The entire power grid voltage is rising. Therefore, a lamp with a rated power of 250W actually works at around 560W, consuming twice as much electricityCan.

1The maintenance cost of the equipment is high.Due to the overloaded operation of street lamps in the late night, the service life of street lamps has been greatly shortened, with an average actual service life of less than one year. The cost of replacing one lamp is about 120 yuan. If a city has 20000 lights, the annual cost of replacing them would be over 2 million yuan, creating a significant contradiction between the tight municipal expenses and the maintenance costs of street lighting.

2Outdated monitoring management leads to power waste.At present, most street lighting systems use timed and manual control methods for lighting control. Due to the time difference throughout the year, using a timer control method often requires adjusting the timer, which not only consumes a lot of human resources, but also causes power waste due to untimely manual adjustments.

Solution Value

1energy-saving control

After the system is built to save energy expenditure costs, it can detect the status of street lamp switches, effectively avoiding the occurrence of daytime lighting. The system can change the timing of street lamp switches for each line at any time according to the seasonal changes throughout the year, and can also turn on and off lights at any time according to weather changes. While meeting the lighting requirements, it can minimize the turning on time and save energy as much as possible.

2. Efficient operation and maintenance

The system for reducing operation and maintenance costs has changed from searching for faults on patrol lights to waiting for alarms on duty, reducing the number of patrol personnel and vehicles, lowering maintenance costs, extending the service life of street lights, and reducing operating costs.

3. Real time monitoring

Real time understanding of various electrical parameters and electricity consumption levels in different time periods provides a basis for energy conservation. Real time understanding of various electrical parameters and electricity consumption levels in different time periods allows for real-time monitoring of the system's operating status, analysis of the system's energy consumption status, identification and control of unnecessary energy consumption, and reduction of operating costs.

4. Fault analysis

Line faults can be determined through data analysis by real-time detection of current and power. If there are 10 lamps with 2000W and only 1800W detected in real-time, it indicates that one lamp is damaged. If there is only voltage and no current, it indicates that there is a fault in the line.
