Introduction to LED Drivers

Light Emitting Diode (LED) are becoming increasingly popular in the modern age, allowing for more efficient lighting sources in terms of both energy consumption and longevity. In order to achieve this efficiency, LED requires a driver to provide them with a constant current and voltage rating. This is where an LED Driver comes in.

What is an LED Driver?

An LED Driver is an electronic component which suppresses electrical noise and regulates power to LED circuits, allowing for the efficient functioning of an LED lighting source. LED drivers provide a constant current flow, aiding in greater LED efficiency as compared to alternative sources such as incandescent, or halogen bulbs.

Uses of LED Drivers

LED drivers have many applications, ranging from domestic uses, such as in homes and offices, to industrial applications, for example in manufacturing facilities. They can be used to power LED lighting fixtures, including bulbs, tubes, panels, and strips. LED drivers can also be used in signboards, and cinema screens as they provide a constant level of output without risk of flickering or dimming.

How do LED Drivers Work?

Typically, LED drivers are connected to a DC voltage source, such as a battery or power supply, and are designed to adjust the applied voltage in response to the LED circuit current. A current sensor is coupled to the driver output to detect the LED current. A voltage-regulating circuit is usually used to achieve constant current control by adjusting the output voltage in proportion to the LED current.

Types of LED Drivers

There are several different types of LED Drivers, ranging from switched-mode drivers to linear LED drivers. A switched-mode driver is the most efficient and cost-effective type of LED driver, as the switching frequency is adjustable. This adjustment can be carried out depending on the type of application the LED driver is used for. Linear LED drivers are the most common type of LED driver, as they do not generate any electrical noise.

LED12W120-048-C0250-LT Application Field and Working Principle

The LED12W120-048-C0250-LT is a type of linear LED driver. This driver is designed to provide constant current control in LED lighting application with a 12 Volt DC input and a maximum output load current of 250mA. The driver has a built-in thermal protection circuit, allowing it to shut down if the operating temperature exceeds a certain threshold. The LED12W120-048-C0250-LT driver works by adjusting the output voltage level based on the LED current, in order to achieve constant current control.
