Electrolytic capacitors play a crucial role in LED driver circuits, directly influencing the performance and lifespan of power supplies. To address this limitation, many packaging manufacturers have introduced "de-powered" solutions. However, these de-energization approaches still face numerous technical challenges, which is why constant current driving schemes remain dominant in lighting fixtures today.
To enhance the performance and longevity of LED drivers, electrolytic capacitor manufacturers have continuously improved their products through technological upgrades and automated production. Among them, Guangdong Huangshi Electronic Technology Co., Ltd. (referred to as "Huangshi") has focused on the research, development, and production of aluminum electrolytic capacitors for years, striving to build a strong, independent brand in the industry.
With rising global demand for aluminum electrolytic capacitors, Huangshi has invested heavily in fully automated production and testing equipment, significantly expanding its manufacturing capacity. The company now produces 60 million aluminum electrolytic capacitors annually, making it the largest mini-aluminum electrolytic capacitor manufacturer in China. Additionally, Huangshi adheres to strict quality management systems such as ISO9001 and ISO14001, ensuring consistent product quality.
Since its establishment in 2001, Huangshi has maintained close technical collaborations with industry leaders in Japan, South Korea, and Taiwan. As a result, its products are now among the best in domestic markets, excelling in high-temperature resistance, high-voltage tolerance, ripple current handling, and high-frequency performance—matching or even surpassing foreign counterparts.
Huangshi’s success stems from a culture of innovation. Recently, the company launched the "LH Series," a new product line that aligns with market trends by offering high-temperature resistance up to 130°C and a service life of 5,000 hours. It also introduced the "LE Series," designed for lighting applications requiring an impressive lifespan of 20,000 hours. To meet the growing demand for automation, Huangshi developed the "TF/TG Series" for SMD applications, replacing traditional DIP components and improving efficiency while reducing costs.
Huangshi has gained recognition from both domestic and international clients, including major companies like Zhaochi Lighting, Sanxiong Aurora, Hailai Lighting, Kaiyao Electronics, Gree Electric Appliances, Panasonic, and Feit. Its commitment to quality and customer service has earned widespread praise.
According to Cai Jiayou, a key figure at Huangshi, “We’ve faced many challenges along the way, but we've always prioritized innovation in products, equipment, management, and services. We continue to push for progress, aiming to maintain our leadership in the industry and deliver maximum social value.â€
Leveraging its advanced technology in high-temperature-resistant, long-life capacitors, Huangshi entered the 2017 High-Tech LED "Technology Innovation Award" competition, showcasing its commitment to technological advancement and industry leadership.
