LED Drivers

LED drivers are electrical devices that provide the accurate power to drive LEDs and support them for a sustained brightness. In essence, they control the level of electrical current applied to an LED. LED drivers come in many different form factors, such as switching regulators, linear regulators, constant-current drivers and also provide additional features, such as dimming capabilities and over-voltage/over-temperature protection. One of the most common LED drivers is the 100 Watt-032 LED driver, which is a constant current LED driver.

LED100W-032 Application Field

The LED100W-032 LED driver is designed to drive LEDs in a variety of applications, such as commercial lighting, industrial lighting, automotive lighting and decorative lighting. It can also be used in signage, medical and many more applications. The LED100W-032 driver is a constant current LED driver, which means that it can provide the LEDs with a consistent and steady output of power, regardless of environmental factors. It does this by constantly adjusting its output voltage to match the changing input voltages. This provides an ideal solution for driving a wide range of LED light bulbs, LED light fixtures and LED display boards.

LED100W-032 Working Principle

The LED100W-032 LED driver uses a unique constant-current buck control circuit to regulate output current. The control circuit consists of a voltage feedback circuit, a constant current source circuit and a voltage regulator circuit. The voltage feedback circuit monitors the output voltage of the LED and compares it to a reference voltage. If the LED voltage exceeds the reference voltage, then the current source circuit quickly decreases the output current, thereby maintain a constant current output over a wide range of LED voltages.The voltage regulator circuit consists of a field-effect transistor (FET) with a small sense resistor in series. The sense resistor allows the LED driver to measure the LED current, and the FET is used as a switch, which short-circuits the output path if the LED current exceeds the set current limit. This maintains a constant brightness and color for the LEDs, even when the input voltage changes. The LED100W-032 driver also features a wide input operating voltage, a built-in over-temperature, over-current and short circuit protection circuit, and an adjustable output current. With its versatile design, the LED100W-032 driver can provide LED lights with a consistent and reliable output of power for a wide range of applications.
