In today's world, where energy efficiency and environmental sustainability are at the forefront of global trends, LED lighting has rapidly gained popularity. As a result, LED bulbs have become widely recognized in households around the world. With continuous advancements in technology, the cost and performance of LEDs have significantly improved. Yinlianbao Technology specializes in leveraging its expertise in power management solutions to offer comprehensive systems tailored for LED lighting applications. Drawing from its extensive experience in industrial settings, the company consistently develops new LED driver solutions that cater to diverse market demands, driving the growth and innovation 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 for achieving high power factor (PF), low total harmonic distortion (THD), and precise constant current control for LED lighting. The chip incorporates proprietary "super-PFC/PSR" and "min-THD control architecture" technologies, enabling conversion efficiencies of up to 90%, 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 that supports quasi-resonant (QR) and DCM operating modes. It also includes built-in load adjustment compensation and AC line voltage compensation, which greatly enhances the accuracy of the LED output current. The chip's maximum operating frequency is limited to 90kHz, and it uses a soft-gate drive output to improve the conduction and radiated EMI performance of the LED power supply.
Additionally, the SFL950 employs quasi-resonant (QR) control, which minimizes switching losses through valley switching, thereby significantly boosting energy conversion efficiency. The chip offers an exceptionally wide VDD operating voltage range, making LED system design more flexible and convenient. Whether you're working on residential or commercial lighting projects, the SFL950 provides a reliable and efficient solution that meets modern lighting requirements while contributing to sustainable development.
VCM Parts
VCM (Voice Coil Motor), the Voice Coil Motor in electronics, is a kind of Motor. Because the principle and loudspeaker similar, so called voice coil motor, with high frequency, high precision characteristics.
Its main principle is in a permanent magnetic field, by changing the motor coil DC current size, to control the stretching position of the spring, so as to drive up and down movement.
VCM is widely used in mobile phone cameras to realize the function of autofocus. Through VCM, the position of the lens can be adjusted to present clear images.
VCM is include of Shield Case, Frame, F.Spacer, F.Spring, Yoke, Magnet, Coil, Carrier, B.Spacer, B.Spring, Base.
