The LED lighting power source is a switching power supply. The use of aluminum electrolytic capacitor filter is an essential part of the switching power supply design. The normal working life of the switching power supply depends on the life of the aluminum electrolytic capacitor used by the power supply, and the life of the capacitor is related to the design life and working temperature of the capacitor itself. According to the operating conditions of the LED lighting power, the aluminum electrolytic capacitors must have the following specific technical requirements:

1. The reliability of electrolytic capacitors requires long life, high reliability and good electrical performance parameters.

2. The electrolytic capacitor should be able to withstand high temperature, such as power for high power road lighting, water proof in outdoor use, and sealed shell in manufacturing. In order to improve the protective grade manufacturer, the heat dissipation of the capacitor is greatly affected. The working environment of the electrolytic capacitor in the shell is like a thermos bottle, and the temperature is like a thermos bottle. Accumulation cannot be scattered.
