The Application of Supercapacitors in LED Lights

With the continuous shortage of global energy, how to save energy and protect the environment has become an important issue. Among these energy sources, solar energy is an ideal and easy-to-obtain renewable energy source, while supercapacitors are rare green energy storage elements that are pollution-free to the environmen, green environmental protection and no pollution.

Why choose supercapacitors for LED lights? Because the input voltage of the solar cell is unstable, the solar lamp can only emit light when the light is weak. It needs to be equipped with a power storage device, but the working time of the battery is short, the current speed is slow, and it is easy to pollute the environment. Compared with the battery, solar cells and LED lamps can be used for a long time. If the LED lamp is equipped with a battery, the working time of the battery is short and it is easy to cause trouble for maintenance.

The supercapacitor is different. The supercapacitor is a new type of energy storage element between the battery and the traditional capacitor. It is also an electrochemical element. It can store a large amount of energy. No chemical reaction occurs during the energy storage process, and this reaction is reversible. Yes, supercapacitors can be charged and discharged hundreds of thousands of times and can be used for a long time. Therefore, supercapacitors are used in LED lamps due to their long working time and fast charging speed.

The LED lamp is composed of a control circuit, an LED driving booster voltage regulator circuit, and a light control circuit. When the light is strong, the solar cell can be used to charge the super capacitor, and the LED is also turned off. At night or when the light is weak, the super capacitor power supply drive circuit can turn on the LED to emit light.

The LED light composed of super capacitor and solar energy consumes less power, does not pollute the environment, and has strong irradiation light. It is suitable for lighting the roadside and other environments in dim environments, bringing great convenience to people.

Select a reliable manufacturer when purchasing super capacitors can avoid a lot of unnecessary trouble. JYH HSU (or Dongguan Zhixu Electronics) not only has full models of ceramic capacitors with guaranteed quality, but also offers worry-free after-sales. JEC factories has passed ISO9001:2015 quality management system certification; JEC safety capacitors (X capacitors and Y capacitors) and varistors have passed the certification of various countries; JEC ceramic capacitors, film capacitors and super capacitors are in line with low carbon indicators.
