What characteristics or requirements should the driving power supply for LED solar street lights have?
The manufacturers of solar street lights summarize the following main aspects:
1. Reliability and Lifespan:
The lifespan of the driving power supply should match that of the LED solar street light. Especially since the driving power supply for LED solar street lights is installed at a height, maintenance is inconvenient and costly.
2. Efficiency:
The luminous efficiency of LED light sources decreases as the temperature increases, making heat dissipation very important. A high-efficiency power supply generates less power loss and reduced heat inside the lamp, which minimizes the temperature rise of the lamp and is beneficial for delaying the light decay of LED light sources.
3. High Power Factor:
With the increasing requirements for power supply quality, there is growing concern about the power quality issues brought by electrical devices. The government may establish certain standards regarding power factors.
4. Constant Current Drive:
One method uses a constant voltage source to supply multiple constant current sources, with each constant current source providing power to individual LED light sources. This approach is flexible; if one LED fails, it does not affect others, but costs are slightly higher. Another method is direct constant current supply, with LEDs connected in series or parallel. This is cheaper but has less flexibility, and it needs to address the issue of LED failure affecting the operation of others.
5. Protective Features:
LED solar street lights should include standard protective features, in addition to integrating negative temperature feedback for LED light sources to prevent overheating. The external installation of lamps should ensure waterproof and moisture-proof characteristics, and the casing should be UV-resistant.
