With the slowdown in the LED lighting market, fierce market competition has inevitably spread to the field of capacitors as the core components of power supplies.
The market performance of liquid capacitors is particularly strong in terms of quality, price wars and lifespan.
Solid-state capacitors have also begun to emerge in the market and have occupied some high-end power territories.
The promotion of solid capacitors is too high, and the cost pressure is too large. It is the common aspiration of many power companies. Liquid capacitors are constantly reducing their prices. For medium and small power supply companies that are currently at a reduced cost and price stage, solid-state capacitors are generally far away.
For power companies, most of them are more inclined to liquid capacitors. Yang Dong, general manager of Zhangfei Power, said, "Liquid capacitors are cheaper and suitable for medium and small power supplies. In 2016, liquid capacitors will have a price reduction of about 10%. In recent years, solid capacitors will not replace liquid capacitors. â€
On the contrary, there is no shortage of people in the industry who believe that solid capacitors are the future development trend and have a promising future.
The biggest short board of LED power supply is difficult to guarantee the life. In the view of Liu Yongzhen, the chairman of Emerald, it is necessary to completely solve the impact of electrolytic capacitors on the LED driving power supply and the life and characteristics of the LED whole lamp. Only solid capacitors can be completely solved.
Solid-state capacitors rely on solid conductive polymers as electrolytes. The principle of conduction is to rely on electrons for conductivity, superior conductivity, superior overall performance, and no electrolyte leakage, which protects other components of the circuit.
At present, many high-end power companies are beginning to pursue product life and performance improvements, and solid capacitors can just cater to demand.
Zhang Xiaobo, general manager of Emerald, said, “Power supply companies in the high-end market are constantly improving their performance and quality requirements. They are more willing to choose solid capacitors with higher stability and longer life. Switching solid capacitors has become a trend.â€
Higher prices have always been a stumbling block to the promotion of solid capacitors. Zhang Xiaobo said, “In the future, we will improve the stability of our products by improving R&D technology, reducing the cost of materials and the development cycle, helping our customers achieve greater added value and gradually replacing liquids. capacitance."
Also optimistic about the future prospects of solid capacitors is the Aiwa Group.
One of the investment directions for Hunan Aihua Group, which was listed in May 2015, is the industrialization project of polymer solid aluminum electrolytic capacitors. The project plans to invest 80 million yuan.
"In the future, the pace of popularizing solid-state capacitors in the LED field will be getting closer and closer, especially after the breakthrough in voltage, the fields that can be replaced will become more and more extensive." Some insiders said.
