Public lighting of grid lamps

Intelligent switching power driver: (1) has lighting control and intelligent MCU chip control system, which can automatically detect the ambient brightness, automatically switch on and off the LED power supply, and automatically control the street lamp switch with the change of natural light to prevent the waste of street lamp misoperation under sunlight. Intelligent operating system with unmanned management. (2) It has the function of time control and adjustment, and reduces the loop current within a set time range according to the road traffic conditions, thus reducing the illumination. Can save energy by more than one third. (3) It has high temperature safety protection. In order to give full play to the work efficiency and long life of LED lighting, it is necessary to ensure that LED works in a good environment. This product has the function of over-temperature (> 70℃) protection, so that it can work automatically at a safe temperature without losing its lighting function. In the lighting design, a unique secondary optical treatment is adopted, and different parts of the light source are arranged at different angles (ordinary optical treatment has only one angle), so that the light source is refracted and concentrated on the target, which expands and increases the illumination uniformity on the road area.

The unique heat dissipation system is adopted to guide the temperature generated by the light emitting diode to the lamp shell of the street lamp, and natural air is used for convection heat dissipation, so that the structure is simple, the heat dissipation effect is good, the weight is less than one third of that of the ordinary LED street lamp, the original structure of the street lamp is maintained in appearance, the requirements of street lamp fluid mechanics and wind resistance are met, and the use safety is ensured; Adopt the international advanced LED power chip technology, abandon the traditional large capacitance filtering, and ensure long-term reliability. Advanced power chip control and circuit topology make its work more stable. The input power factor is increased to ≥0.95, and the current harmonic (THD) content is reduced to 5%-8%, which minimizes the pollution to the power grid and meets the harmonic requirements of relevant international standards. The ordinary LED street lamp power supply uses bridge rectifier to increase capacitance filtering, and the power factor is only about 0.6. Non-self-ballasted LED module is selected and matched with drive control circuit to realize constant voltage, constant current or constant power operation. Ensure that each string of LEDs works at 98% rated voltage and current. With the cooperation of the reference drive controller, the LED works stably under the rated voltage (current), and the actual power consumption does not exceed 1.05% of the rated power, which ensures the slow light decay of the LED street lamp and meets the service life of more than 50,000 hours. According to the special environment of street lamps, this series of products have special surge protection design. When the surge voltage of the power grid exceeds 300V, the switching power supply automatically protects and closes the circuit. When the peak surge voltage drops below 300V, the switching power supply will automatically recover. This process is instantaneous, which not only ensures the safety of power supply and light source, but also does not cause high voltage to stop working, resulting in instantaneous darkness and road safety accidents.
