1. High reliability: This kind of driving power supply of
solar street light is installed at high altitude, so maintenance is inconvenient and the maintenance cost is naturally large. 2. High efficiency: LED is an energy-saving product, so the efficiency of the driving power supply must be high. The heat dissipation of LED is very important, because the luminous efficiency of LED decreases with the increase of LED temperature, so the efficiency of the power supply is high, its power consumption is small, and the heat generated in the lamp is small, which reduces the temperature rise of the lamp. . It is beneficial to delay the light decay of LED. 3. High power factor: The power factor is the requirement of the power grid for the load. Generally, there are no mandatory indicators for electrical appliances below 70 watts. Although the power factor of a single electrical appliance with low power is low, it has little impact on the power grid, but everyone turns on the lights at night, and the same load is too concentrated, which will cause serious pollution to the power grid. For 30 watts to 40 watts of LED drive power, it is said that in the near future, there may be certain index requirements for power factor. 4. Driving mode: one is a constant voltage source for multiple constant current sources, and each constant current source supplies power to each LED individually. In this way, the combination is flexible, and the failure of one LED will not affect the work of other LEDs, but the cost will be slightly higher. The other is direct constant current power supply, with LEDs running in series or parallel. Its advantage is that the cost is lower, but the flexibility is poor, and it also needs to solve the problem of a certain LED failure without affecting the operation of other LEDs. These two forms coexist for a period of time. The multi-channel constant current output power supply method will be better in terms of cost and performance. Maybe the mainstream direction in the future. 5. Surge protection: The ability of LED to resist surge is relatively poor, especially the ability to resist reverse voltage. Strengthening this protection is also important. Some LED lights are installed outdoors, such as solar street light. Due to the start-up of the grid load and the induction of lightning strikes, various surges will invade from the grid system, and some surges will cause damage to the LED. Therefore, the LED drive power supply must have the ability to suppress the intrusion of surges and protect the LED from being damaged. 6. Protection function: In addition to the conventional protection function of the power supply, it is better to increase the negative feedback of the LED temperature in the constant current output to prevent the LED temperature from being too high. 7. In terms of protection: the lamp is installed outside, the power supply structure should be waterproof and moisture-proof, and the shell should be resistant to sunlight. 8. The life of the driving power supply should be adapted to the life of the LED. 9. To meet the requirements of safety regulations and electromagnetic compatibility.
