What is a CCFL?

CCFLs, or cold cathode fluorescent lamps, are lighting technology that uses a mixture of inert gasses to create light, which means a filament doesn't electrically heat it. These are commonly used in backlight liquid crystal displays (LCDs) and work when a high voltage is placed across the tube, and the gasses ionize, creating ultraviolet (UV) light. After that, the UV light produces an inner phosphor coating, which makes the visible light.

The Role of CCFL Inverters in Cold Cathode Fluorescent Lamps

Since high voltage is required to power cold cathode fluorescent lamps, our CCFL inverters are widely used to convert a low DC supply to a high voltage AC. It employs high-frequency SMPS technology to switch the DC using transistors in a push-pull configuration into the primary. It's also equipped with a feedback winding output to provide positive feedback to make the circuit oscillate.

The CCFL inverter is integral to the cold cathode fluorescent lamp's circuit operation. Therefore, some parameters must be considered, such as leakage inductance, winding resistance, and turns ratio. Isolation requirements must also be considered, mainly because the circuit generates a higher "strike" voltage to start the tube before it runs into a consistent running state.

The Main Advantages of Using CCFL Inverters

Numerous devices, equipment, or machines that need bright lighting utilize cold cathode fluorescent lamps because of their high-performance lighting. Some of its benefits include:

• Excellent source of white light: A CCFL can produce a bright white light, making it ideal for lighting applications.
• Energy efficiency: Compared to other lighting technologies, CCFLs use significantly less energy, making them more cost-effective in the long run.
• Long lifespan: With proper handling and maintenance, a CCFL can last up to 50,000 hours or even longer.
• Stable operation: CCFL inverters provide a steady power source for cold cathode fluorescent lamps, ensuring consistent lighting output.

What are the Common Applications of CCFL Inverters?

Due to their compact size, efficiency, and stable output voltage, CCFL inverters are well-suited for use in various applications. From the entertainment industry to the stringent medical sector, CCFL inverters can provide a reliable and efficient power supply for cold cathode fluorescent lamps.

The most common use of CCFL inverters is for LCD backlight applications. However, it has plenty of other uses, including:

• Computer monitors and televisions
• Mobile phones
• Medical instrumentations
• Aquarium lighting
• Test equipment
• TFT matrixes
