Natural condition has great influence on the solar street light for it always works outdoors. Thus something should be done to increase its resistance against bad weather conditions to guarantee the service time of the solar street light system. However, it may meet the condition that the service time of the solar street light is short, and what influences the service time of the solar street light?
Generally speaking, there are several factors that influence the service time of all in one solar street light, and they are the light source, light source starter, solar controller and the accumulator.
-
A. The light source starter
-
Different ballasts or driving power lights should be adopted according to the difference of the starting methods, which has great influence on the light source, especially for the LED light source. The constant current source drive is usually applied to the solar street light. It is quite important that if the quality of the constant current source and the range of set parameters can suit the light source, and main parameters are the constant current accuracy, output efficiency, protection circuit and range of the set parameters.
-
B. The light source
-
Different light sources differ in service time, and the light sources can be chosen are low-pressure sodium lamp, low-voltage electrodeless lamp, LED lamp and low-voltage fluorescent lamp. The sodium lamp and the LED lamp are widely used nowadays. However, the sodium lamp is cheap, but with short service time; the high-quality LED lamp can work for 500,00 hours, and in theory, it works 10 hours a day, which can work for more than 10 years. So it is quite important to choose a good light source for the solar street light.
-
C. The solar controller
-
The solar controller can not only control, monitor and protect the photoelectric cell module, accumulator, but protect the load indirectly, and provide an effect and stable working environment for it, especially under the critical condition of low power condition or undervoltage condition of the accumulator. A controller with high accuracy and relatively stable plays key role in the solar street light system. Sometimes the solar street light will be glittering, and the breakdown of the controller may be one of the reasons.
-
D. The accumulator
-
The accumulator with stable performance should be applied to the solar street light, and the installation of the accumulator should be strict to avoid the unforeseen factors like water-proof. Otherwise it will influence the service time of the solar street light indirectly.
