Hongtong & Hongsi electronic plug-in LED flat products are high-quality core components specifically designed for the field of electronic precision manufacturing. With their well-organized structure and stable performance, they have become preferred accessories across multiple industries. As a high-tech enterprise with over two decades of experience in the LED field, our company relies on mature packaging technology and rigorous quality control systems to achieve dual breakthroughs in reliability and adaptability for this series of products.
The product adopts a square flat package design, with mainstream models covering specifications such as 234 (2.3mm×4mm), 255 (2.5mm×5mm), and 257 (2.5mm×7mm). The pins are compatible with PCB board direct insertion soldering, ensuring convenient installation and stable connection. The light-emitting colors cover a wide range of options, including red, green, blue, yellow, white, dual-color, and RGB full-color. The brightness range can be customized according to needs, with uniform light-emitting angles and high color saturation, meeting the display and indication requirements of different scenarios.
The core advantages are particularly prominent: the square package brings better heat dissipation performance, adapts to high current drive, and has a working life of over 50,000 hours; strictly follows RoHS/REACH environmental standards, ensures stable operation through full-process quality inspection, and can withstand complex environments such as high and low temperatures, damp heat, etc. The product is widely used in home appliance control panels, industrial equipment indicator lights, instrument backlighting, automotive instrument panels, LED displays, and other scenarios, which not only meets the needs of mass production but also supports personalized customization services.
Relying on the company's more than 40 LED bead production lines and precision testing equipment, this series of products achieves large-scale monthly production capacity, with fast delivery of 3-7 days for general models, providing stable supporting support for partners such as Huawei and ZTE.
