The JUK universal Screw Terminal Block series has the typical features which are decisive for practical applications:
l The universal foot allows the terminal blocks to be easily snapped onto the NS35 or NS32 DIN Rail with G shape.
l Closed screw guide holes ensure screwdriver operation perfect.
l For terminal block with different wire cross-sectional areas, complete accessories are available, such as end plates, partition plates, etc.
l Potential distribution achieved by fixed bridges in the terminal center or insertion bridges in the clamping space.
l Same shape and pitch Grounding Terminal Blocks as the JUK universal series.
l Adopt ZB marker strip system,achieve unified identification.

[High School Annual Meeting] Mingwei Electronics Li Zhaohua: IC power makes landscape lighting and general lighting simple and clear
Mingwei Electronics has been actively developing linear IC power supply solutions in Shenzhen for several years, making significant progress in both indoor and outdoor lighting applications.
On the afternoon of December 22nd, the "High-tech domestic power supply ideally shines into reality" event was officially launched at the 2017 High-tech LED Annual Conference. This marked an important milestone in the industry's push toward more efficient and intelligent lighting systems.
During the conference, Li Zhaohua, General Manager of Mingwei Electronics, delivered a keynote speech titled “IC Power for Landscape Lighting and General Lighting.†In his presentation, Mr. Li shared insights on how linear IC technology is transforming both general and landscape lighting, offering greater efficiency, flexibility, and reliability.
The speaker highlighted that LED general lighting has long been a focus, with standardization moving from traditional switching power supplies to more advanced IC-based solutions. However, this shift has also led to increased competition, with many customers facing cost pressures as the market becomes more saturated.
In the case of landscape lighting, government support has played a key role, especially in urban and outdoor lighting projects. For instance, the construction sector sees substantial investment—nearly 10 billion yuan annually from local governments, with Shenzhen alone expecting around 80-90 billion yuan next year. This includes major initiatives like the G20 summit, where high-power outdoor lighting and intelligent RGB systems are being implemented.
Despite these advancements, there are still challenges in achieving fully immersive, situational lighting. Mr. Li emphasized that while general lighting is evolving toward more dynamic and smart solutions, current technologies still have limitations. That’s why outdoor high-power lighting remains a critical area, combining both functional and aesthetic elements.
He also noted that the lighting industry has evolved significantly over the past few years. At previous senior worker meetings, the focus was on creating simple, reliable solutions. Now, with mass production, the market is entering a more competitive phase, and the coming year may bring even more intense competition.
To stand out, Mr. Li explained that the industry is focusing on versatility, including dimming capabilities. He pointed out that linear IC solutions make dimming easier and more efficient. With changing customer demands, he believes the best approach is to use the least number of peripheral components and the most reliable chip solutions. Big players in the industry are increasingly turning to linear technologies.
In outdoor landscape lighting, particularly for high-power applications, simplicity remains key. According to Mr. Li, many large companies are now adopting linear solutions, and Mingwei’s linear power supply can achieve over 93% efficiency at 200 watts or even 300 watts.
Looking ahead, Mingwei is working on integrating dimming and color control into its outdoor linear solutions. As intelligent control interfaces become simpler, the need for complex power supply systems is decreasing, which improves user reliability.
Mr. Li is optimistic about the future of intelligent lighting. He believes 2018 will be a pivotal year, with intelligent lighting starting to grow rapidly. Currently, it's still in its early stages, but once embedded in platforms like Alibaba or WeChat, it could truly transform how we interact with our environments.
As the lighting industry continues to evolve, companies like Mingwei Electronics are leading the way by pushing the boundaries of innovation, efficiency, and smart integration.
