How to distinguish the quality of smart street lights

1. Look at the overall 'power factor of the lamp': low power factor means that the driving power and circuit design used are not good, which will greatly reduce the service life of the lamp and the power factor is low. No matter how good the lamp beads are, the life of the lamp will not be long. 2. See 'Heat Dissipation Conditions of Lamps-Material and Structure': The heat dissipation of smart street lamps is also very important. For lamp beads with the same power factor and the same quality, if the heat dissipation conditions are not good, the lamp beads will work at high temperature and the light will decay. Very large, the lamp life will be reduced. 3. Look at the 'quality of lamp beads': the quality of lamp beads is determined by the quality of the chip and the packaging process. 4. Look at the driving power used by the lamp. The life of the power supply is much shorter than the other parts of the lamp. The life of the power supply affects the overall life of the lamp. The theoretical life of the lamp beads is 50,000 to 100,000 hours, and the life of the power supply is between 0.2 and 30,000 hours. The design and material selection of the power supply will determine the life of the power supply. 5. Look at the light effect: the higher the light effect of the same lamp bead, the higher the brightness. The same lighting brightness, the lower the power consumption, the more energy saving. 6. Look at the power efficiency. The higher the power efficiency, the better, and the higher the power, the smaller the power consumption of the power supply itself, and the greater the output power. 7. See if it meets the safety standards? my country's smart street light safety standards have been promulgated, please choose smart street lights in accordance with the national safety standards. 8. It depends on the workmanship.
