The biggest feature of solar LED solar street light is that it is usually powered by a battery, and the battery has some characteristics that need to be considered: 1. The battery has only several specified voltages, and 12V is the most commonly used, because it is a car battery. Standard Voltage. 24V requires two in series. 36V is even rarer. For this reason, a boost-type constant current drive module is often required in solar LED solar street light. This affects the efficiency of the constant current module. 2. Another issue that needs to be considered in solar street light is the change of input voltage. For the output power and efficiency of the constant current source, in order to obtain the highest efficiency, it is necessary to keep the ratio of the input and output voltage as close to 1 as possible. But if the input voltage is unstable. Then it is very difficult to maintain the optimum state of the highest efficiency. Solar LED solar street light systems usually use batteries as energy storage units. The voltage of the battery will change greatly when it is just fully charged and when it is about to be discharged. Usually this change is more than 30%. For example, for a 12V battery, the output voltage can vary from 14.8V to 10.8V. Of course, for constant current modules, such changes are completely acceptable. That is, the output current can be kept constant within such a large variation range. But it also comes at a price, which is not working optimally. The so-called optimal state refers to the most efficient state. or the state with the highest output power.
