Recently, the largest-scale DC-powered urban-level intelligent LED street lamp renovation project implemented by Nanwang Energy Co., Ltd. – Zhaoqing High-tech Zone Street Light LED Energy-saving Reconstruction Project entered the construction climax, and the street lamp transformation has been completed 5,600 盏, and the power saving rate has reached 60%, the road illumination is increased by 20-30%, and it is expected that all 7500 street lamps will be completed at the end of February.

The DC centralized power supply and intelligent control system built by the project integrates various technologies such as cloud platform, IoT perception, control and data processing. Through the intelligent control system, various functions such as dimming control can be realized, and the mobile terminal can also be used. The remote monitoring of the lamps and lanterns truly realizes the intelligent and refined management of the lighting system, which greatly prolongs the service life of the lamps and systems, and greatly reduces the maintenance cost of the street lamp system.


The original ordinary street lamp head was transformed into a new type of LED street lamp with low energy consumption, high brightness and wide illumination range, which fully utilized the advantages of high efficiency and energy saving of LED street lamps, effectively improved the road lighting situation, improved the public security environment, and carried out the night travel for the masses. It’s convenient.

DB-S Diode

DBS diode series patch rectifier bridge stack is composed of 4 rectifier diodes connected and packaged in the form of a bridge full-wave rectifier circuit, which belongs to a full bridge. There are four lead-out pins, the connection point of the negative poles of the two diodes is the "positive pole" of the DC output terminal of the full bridge, and the connection point of the positive poles of the other two diodes is the "negative pole" of the DC output terminal of the full bridge. Reverse repetitive peak voltage range: 50V~1000V, average rectified output current 0.8A~1.5A: forward non-repetitive surge current 30A (60Hz sine wave, one cycle, Tj=25°C). For specific parameters, please refer to the specification or consult online customer service.
