How to increase the number of days solar street lights illuminate in a long rainy day

At present, most solar street lights on the market can achieve continuous rainy day lighting for only 3-7 days, but this is far from meeting the requirements of climate change around the world, because the number of continuous rainy days in some areas will appear for more than 7 days, and now Severe air pollution in the world will cause haze weather, which will have a great impact on lighting, and our Changhui solar street lights can reach 2-3 times the conventional technology with the same configuration, up to 15 consecutive days of continuous rainy and cloudy days.

　　The solar street light controller invented by our Changhui can make the energy-saving benefit of our solar street light at 70-85%, which means that our solar street light consumes only 25% of the conventional solar street light with the same configuration. That is to say, if we can achieve 4 days of rainy weather through conventional technology, we can achieve nearly 16 consecutive days of rainy weather. Maybe many people will ask me how to do it? The simple principle is as follows:

　　1. Solar street light LED light source adopts digital drive technology to save 20% power than conventional technology

　　 Most of the light sources used in solar street lights now use LEDs, and LED lighting requires an LED to drive a cross-current source. Conventional constant current sources consume about 20% of the power of the entire lamp, and we often use LED digital constant The power of the current source drive technology is only 0.0625 (IC) W, which is almost negligible, which saves nearly 20% of the power consumption of solar street lights;

　　2, LED digital constant current source drive, achieve intermittent power supply, saving nearly 50% of electricity

　　Conventional technology solar street lights must continuously supply power to the light source when working, and our LED digital constant current source uses intermittent switching to power the LED light source;

　　3. The gradient energy-saving mode of the LED light source in the latter half of the night saves more than 15% energy

　　 The number of pedestrians and vehicles on the road in the second half of the night will be greatly reduced, so you can set an energy-saving lighting mode in the second half of the night. Through intelligent control technology, the power of the LED light source is slowly reduced to the power you need, and then maintained until At dawn, the products of other solar street light manufacturers will suddenly drop to a target value, which is very detrimental to pedestrians and vehicles. Generally, our design is to save energy by about 15% in the second half of the night to ensure that there is enough lighting brightness.
