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.
Luxury grille lamp material: the lamp board is galvanized with high-quality organic paint, the middle partition is made of mesh aluminum plate, the reflector and grille are made of imported mirror aluminum, and one grille is made of transparent acrylic grille.
