VAOL-5LDE2 application field and Working Principle

The VAOL-5LDE2 is a general purpose LED indicator with a built-in driver. It is a 2-in-1 module made up of an LED chip and a discrete driver IC. The discrete IC measures and controls the current in the LED chip, providing improved accuracy, reliability and uniformity compared to off-the-shelf LEDs.

The VAOL-5LDE2 is designed to be suitable for a wide range of applications such as automotive lighting, consumer electronics, signs and displays, and industrial applications. It is a robust and reliable solution for designers who require high accuracy, performance and reliability in their LED applications.

VAOL-5LDE2 Features and Advantages:

• High performance and efficiency: The integrated discrete driver IC and LEDs provide up to 11.5mA per diode with a 1kΩ resistor.
• Low power consumption: The power dissipation of the VAOL-5LDE2 is as low as 2mW, which not only reduces the temperature rise of the module, but also extends the life of the device.
• High reliability: The VAOL-5LDE2 is designed to operate over a wide temperature range of -40/+85°C. The module is highly integrated and sealed with a moisture resistant sealant to protect against condensation and to extend product life.
• Easy to install: The module comes with pre-soldered leads, making it easy to install and suitable for surface mounting.

VAOL-5LDE2 Working Principle

The discrete driver IC measures the current passing through the LED chip and then adjusts the current passing through the LED chip accordingly. This is done by monitoring the voltage drop over the chip and adjusting the current to get the desired level of brightness. The discrete driver IC is integrated with the LED, so that the current is monitored at all times and the LEDs are driven in a highly accurate and efficient manner.

The VAOL-5LDE2 module also includes a temperature-sensing circuit which monitors the temperature of the LED chip and adjusts the current accordingly. This ensures that the LED chip is not over-heated, which would adversely affect the lifetime of the device.

The discrete driver IC is powered by an external power supply and is controlled by a user-selectable input. The input can be selected from a number of different options, such as on/off, dimming, blinking, flashing, pulsing and so on.

The VAOL-5LDE2 also includes a reverse current protection circuit which prevents current from flowing in a reverse direction. This helps keep the LEDs and the driver IC safe in the event of a power surge or a short circuit.

Conclusion

The VAOL-5LDE2 is a highly efficient, reliable and robust LED indication solution designed to meet the needs of a wide range of applications. It is a great choice for designers who need a reliable, accurate and efficient LED indication solution.
