[Text / Long Zonghui] In the past, everyone questioned that many lamps and other quality problems such as dead lights generally point to the driving power supply. In fact, the culprit is often a capacitor. There is a saying in the industry that "the life of an electrolytic capacitor is the life of an LED driver."
Compared with traditional power supplies, LED driver power supplies require more stringent capacitors. It includes continuous operation in high temperature environment, matching LED long life, low impedance value at high frequency, miniaturization, flattening and low temperature characteristics of outdoor special occasions.
The defects of traditional liquid capacitors such as poor temperature characteristics, poor electrical conductivity, large impedance, short life, and poor safety are becoming more and more prominent. When the operating temperature of the liquid capacitor exceeds 125 ° C, the life will be shortened rapidly. Under the extremely low temperature conditions below -40 ° C, the activity of the liquid power source will be reduced, and the electrical performance of the circuit will be weakened.
In addition, the liquid capacitor uses the electrolyte as the dielectric material, and can not get rid of the thermal expansion due to physical properties, and the danger of liquid leakage occurs, which makes the liquid capacitor become a major bottleneck of the LED driving power source.
Finding solutions that can replace liquid capacitors is imperative.
As an important part of the driving power supply, the capacitor faces new challenges and opportunities in terms of performance and cost.
Luo Wei, deputy director of Zhaoqing Emerald Technology Center, will give a keynote speech on the comparison of the effect of solid-state capacitors instead of liquid capacitors on the 1-7WMR16 small spotlights in the high-tech LED conference driving power supply and intelligent control on the afternoon of November 26. At that time, he will share with you the common faults of MR16 small spotlights, the comparison of the characteristics of solid capacitors and liquid capacitors for MR16 small spotlights, and the life and application examples of solid capacitors.
