Most of the solar street light controller is installed in the lamp cover and battery storage box, generally will not enter the water, but in the actual project cases, due to improper installation or controller and part of the circuit board did not carry out 3 kinds of paint prevention treatment. Because rainwater will short circuit along the controller terminal line into the solar street light controller. In many practical applications of solar street lights, solar street lights can not meet the normal lighting requirements, especially continuous rainfall days and winter blackout period is more obvious.
1. The quality and type of light source: different types of light sources will affect the life of solar street lights in Henan. Solar street lights are commonly used LED lights, energy-saving lamps and so on. Energy-saving lamps depending on the mark, the average life expectancy of more than 6000 hours, LED lights generally more than 50,000 hours. In other words, energy-saving, etc. can be used for more than 2 years, LED, etc. can be used for more than 10 years. At the same time, the quality of the product, the quality of the quality also determines the life of the light source.
2. Controller: The controller is one of the central components of the solar street light, playing a command role in the entire solar street lighting system, not only can control, monitor and protect the working state of the photovoltaic module, battery and load, but also can effectively control the working state of the battery. Therefore, the controller with stable performance and reliability can greatly extend the service life of solar street light bulbs.
3. Battery: Solar street lights currently commonly used batteries are colloidal and lithium batteries, colloidal batteries are cheaper than lithium batteries, but the life of colloidal batteries is much lower than lithium batteries. At present, the domestic use of colloidal battery life of 4 years, lithium battery life of 5 years, many places are lit up solar street lights.
