POINT TEK has been a design and development business for fabless semiconductors since 2009, continuously striving to deliver the best possible quality. AC direct LED driving technology is the best in the world, especially for high efficiency and flicker-free module operations with less than 1% flicker. The technology is capable of handling any voltage with just one LED module.
Synchronous AC LED driver is a type of LED driver that operates in synchronization with the alternating current (AC) power supply. LED drivers are electronic devices that provide the necessary voltage and current to power and control light-emitting diodes (LEDs). These drivers are used to convert the AC power supply to the DC voltage and current required for LED operation.
In the case of a synchronous AC LED driver, the driver circuitry is designed to work in harmony with the AC voltage waveform, meaning that it adjusts its operation to match the AC power supply's voltage and frequency. This can be achieved through various methods and circuitry, such as phase-locked loops (PLLs), zero-crossing detection, or other synchronization techniques. The benefits of using a synchronous AC LED driver include:
Improved efficiency: Synchronous drivers can optimize the LED power delivery to match the AC waveform, reducing energy losses and increasing efficiency.
Flicker reduction: Synchronization can help reduce flicker, which is a common issue with non-synchronous drivers that can be a concern for human vision and camera systems.
Compatibility with existing AC infrastructure: Synchronous drivers can work well with traditional AC power systems, making them easier to integrate into existing setups.
Dimming control: Synchronous LED drivers can offer smoother and more precise dimming control, which is important in applications like lighting control systems.
The design of synchronous Universal AC drivers can vary, and manufacturers may implement different techniques to achieve synchronization with the AC supply. These drivers are commonly used in residential and commercial lighting applications, where they can provide a more reliable and efficient means of powering LEDs.
