Urban street lighting is an indispensable public facility in people's daily lives. It is understood that the current electricity consumption of street lighting in China accounts for about 15% of the total electricity consumption. In the face of the tight supply situation, manual control and street lamp inspection have become an indispensable reality work, and it is also a work that requires a lot of manpower and material resources. The existing traditional power-saving measures are only realized by turning off the lights at night, adjusting the switching time of the street lights, and turning off the landscape lighting when the electricity is tight. The method is simple and has little effect. In the current LED street lights on the road to explore the country, it is necessary to explore its own LED control system in combination with the characteristics of LED street lights.
It is understood that the current market application of LED drive power management, LED lighting intelligent energy-saving monitoring solutions can be described as rare.
Secondary energy-saving monitoring system with obvious advantages
For the implementation of intelligent control management for street lamps, tunnel lights, square lamps, industrial lighting, etc., it will save more than 80% of manual inspection costs, so there is a strong market demand in the LED industry.
First, energy saving and saving money.
Take the 150W solution LED street lamp as an example; the pole spacing: 30m/rod, double-sided symmetrical lighting, 66 street lights per kilometer; daily dimming time:
Regarding the energy-saving effect of the system, in order to be intuitive, the Maoshuo R&D department calculated an account:
“Increase in input cost per kilometer (batch): 66ç› & TImes; 90 yuan (power carrier module, concentrator) = 5940 yuan;
10 km increase input cost (batch): 660 ç› & TImes; 90 yuan (power carrier module, concentrator) = 59,400 yuan;
Annual maintenance service fee per year: 50 yuan;
Electricity savings per kilometer per year: 66ç› & TImes; 0.31 yuan & TImes; 365 days = 7467.9 yuan;
10 kilometers per year to save electricity costs: 7467.9 yuan × 10 kilometers = 74679 yuan. â€
Second, it is possible to implement a fast maintenance guarantee mechanism service.
Because the LED street lamp fault can be diagnosed remotely and quickly, based on the response of the local service personnel, the average maintenance time control MTTR is less than 8H, and the municipal street lamp management department actually feels that the LED street lamp works normally every night. "
The third is to protect users' early investment.
The existing system, after adding a power carrier module to the power supply, can be directly upgraded to an intelligent street light control system to avoid repeated investment. And the system adapts to the future energy-saving renovation and upgrading of the street lamp management department, such as installing LED street lights, etc., which can directly realize the remote control dimming function and avoid secondary transformation. â€
Fourth, using DALI protocol communication technology to achieve energy saving, environmental protection, multi-function, high reliability and intelligent management.
The solution product is designed around the goal of energy saving, environmental protection, multi-function, high reliability and intelligent management. It also develops the function of “DALI-based lamp work intelligent controlâ€, and innovatively adopts DALI protocol communication technology in traditional power supply. The communication line remotely monitors each LED street light, thereby realizing intelligent management of LED street light switch, dimming, brightness feedback, status inquiry, fault alarm, group control, etc., achieving further power saving and improving LED light use. The purpose of life. From the lighting usage time, the power consumption of the intelligent control LED system is about 3/4 or less of the power consumption of the non-intelligent LED.
