In today's era of energy efficiency and environmental protection, the global LED lighting market is experiencing rapid growth. As a result, LED bulbs have become widely recognized by consumers. With continuous technological advancements, the cost and performance of LED products have significantly improved. Yinlianbao Technology specializes in leveraging its expertise in power management solutions to provide comprehensive and efficient options for LED lighting applications. Drawing from its extensive experience in industrial applications, the company continuously develops new LED driver solutions to meet diverse market needs and support the ongoing development of the LED lighting industry.
For single-segment design applications such as downlights, LED bulbs, spotlights, desk lamps, general LED lighting, and intelligent lighting systems that require high power factor and low harmonic distortion—up to 60W—Yinlianbao Technology has introduced the SFL950 LED driver solution. This isolated Flyback architecture is optimized to deliver high power factor (PF), low total harmonic distortion (THD), and precise constant current control for LED lighting. The chip integrates patented "super-PFC/PSR" and "min-THD control architecture" technologies, achieving up to 90% conversion efficiency, a power factor above 0.92, THD below 10%, and a ±4% constant current accuracy in mass production.
The SFL950 features a patented high-precision closed-loop constant current algorithm, supporting quasi-resonant (QR) and DCM modes. It also includes built-in load adjustment compensation and AC line voltage compensation, greatly enhancing the accuracy of LED output current. The chip’s maximum operating frequency is capped at 90kHz, and it uses a soft drive output for the GATE signal, improving the conduction and radiated EMI performance of the LED power supply.
Additionally, the SFL950 employs quasi-resonant (QR) control, which reduces switching losses through valley conduction, significantly boosting energy conversion efficiency. The chip offers an extremely wide VDD operating voltage range, making LED system design more flexible and convenient. Whether for residential or commercial lighting, the SFL950 provides a reliable and efficient solution that meets modern lighting demands while contributing to a more sustainable future.
Printer Accessories
These printer accessories are include of printer grid, Eliminator,etc.
The cartridge is irradiated by laser beam to adsorb toner, and then the toner is hot pressed by fixing roller for printing. In this process, there will be part of toner residual, which can not be "granules returned to the warehouse"; Automatic cleaning function is not adsorbed new toner particles and directly print, will remain toner away, fully ensure the next printing effect. And the Plate-Grid plays an important role. When high voltage generator to a high voltage electrode, wire electrode with reseau formed between a strong electric field, and release the corona, wire electrode and the photosensitive drum ionizes the air between the air ions migrate to the drum surface, make the photoconductor (drum) surface is full of charge, so can spare toner "adsorption to warehouse", so as to save toner, The purpose of reducing environmental pollution.
