POINT TEK is a firm established in 2009. The flicker-free AC LED driver is designed to eliminate or minimize flicker in LED lighting systems. Flicker refers to the rapid and unwanted variations in light output, often caused by the AC power supply frequency and voltage fluctuations. Flicker can be a concern in LED lighting, as it can lead to discomfort, visual fatigue, and health issues in some individuals. Therefore, flicker-free LED drivers are crucial for applications where flicker is undesirable, such as in residential lighting, office spaces, and healthcare facilities. Here are some key features and characteristics of flicker-free AC LED drivers:

High-Frequency Operation: Flicker-free LED drivers typically operate at a high frequency, which is well above the AC power supply frequency (e.g., 120 Hz or higher). This high-frequency operation ensures that the LED light output remains stable.

Smooth Current Regulation: These drivers use advanced current regulation techniques to maintain a constant current supply to the LEDs, even when the input voltage varies.

Filtering and Compensation: Flicker-free drivers may incorporate filtering and compensation circuits to reduce or eliminate voltage and current variations caused by the AC power supply.

Dimming Compatibility: Many flicker-free LED drivers are designed to work seamlessly with dimming systems, ensuring that flicker is not introduced when dimming the LEDs.

Compatibility with Various Input Voltages: Some flicker-free LED drivers are designed to operate with a wide range of input voltages, making them suitable for use in different regions with varying electrical standards.

Compliance with Industry Standards: Flicker-free drivers are often designed to meet industry standards and guidelines for flicker reduction and may be labeled as "flicker-free" or "low-flicker" in compliance with these standards.

Reducing or eliminating flicker in LED lighting is essential to provide a comfortable and visually pleasing environment for users. It's especially important in applications where prolonged exposure to flickering light may cause discomfort or health issues. When selecting a flicker-free AC LED driver, consider your specific application needs, input voltage requirements, and dimming capabilities to ensure that the driver provides the desired flicker-free performance.
