Discussion on Key Issues LED lighting power supply design

Core Tip: In the LED lighting power supply design, there are several design challenges: life of electrolytic capacitors and LED do not match, a common cause of LED lights flashing and approach, PWM dimming the impact on the life of the LED, use TRIAC dimmer light regulation of potential problems LED brightness. Expand the paper discusses the causes and solutions for these problems.

LED life of electrolytic capacitors and does not match the problem

A LED lighting important consideration is the LED drive circuit and LED operating life itself should be able to be compared. While the impact of the factors driving circuit reliability There are many, but electrolytic capacitors have a crucial impact on the overall reliability. In order to prolong the working life of the system, the need for them to analyze the application of capacitors, and select the appropriate electrolytic capacitors.
