Switching mode power supplies differ from linear power supplies in how the primary AC voltage is converted to an output DC voltage. Switching mode power supplies use power transistors to generate a high frequency voltage which is passed through a small transformer and then filtered to remove the AC component and noise.

When choosing the right LED driver, compatibility is critical. Using the wrong driver in the LED system may cause malfunctions and even damage the components used. As an LED driver supplier, our LED technical team is always ready to provide you with LED suggestions and help you find the right product for you.

High power LEDs produce more lumens per watt than previous lighting technologies and are replacing incandescent and CFL bulbs. When driving high power LEDs, the power consumption in the current limiting resistors can make this method impractical and unattractive. When driving ultra-efficient light sources, very efficient methods are desired. The most efficient way to drive high-current LEDs is to use a DC-DC converter with current feedback.

Every LED luminaire needs an LED driver to power it. There are two different types of device: internal drivers and external drivers.

An LED driver is a converter. Its function is to convert our common mains or other power sources into a voltage and current suitable for LEDs. Through its conversion led can work properly light. As if we want to unscrew a nut, we must use the same type of spanner.

Until the 1970s, linear regulators were the power supply of choice for converting alternating current (AC) to stable direct current (DC) for electronic devices. Although this power supply type is not commonly used today, it remains the best choice for applications requiring minimal noise and ripple.

It is very rare for a good quality LED driver to fail due to a manufacturing fault. In most cases, the failure is caused by an installation issue or there are some environmental factors at play.

First, consider the voltage requirements of your lamp. If your LED requires 12 volts to operate, use a 12-volt driver; if using 24 volts, use a 24-volt driver, etc.

Constant voltage (CV) LED drivers are power supplies. They have a set voltage that is supplied to the electronic circuit. You can use CV LED drivers to run multiple LEDs in parallel, such as LED strips. CV power supplies can be used with LED strips with current-limited resistors, in most cases. The voltage output must meet the voltage requirements for the entire LED string.

First off, let's clarify some terms which often confuse people but are important in selecting the right wall adapter power supply. AC-to-DC "switching" power supplies vs. "linear" power supplies are often misleading terms to those who aren't familiar with them. Linear power supplies take an AC input (typically 120VAC or 240VAC), step down the voltage with a transformer, then rectify and filter the input into a DC output.

Linear power supplies are designed for low noise and are often considered quiet because there is no high frequency switching. They are used anywhere excellent regulation and/or low ripple is required as well as low EMF and excellent transient response. Linear power supplies can only step down the input voltage to produce a lower output voltage.

The advantage of LEDs is that they are highly energy efficient - they don't need a lot of power to make them run. LEDs actually operate on a DC power supply at a fairly low voltage (usually between 2V and 4V). They therefore need something that can convert AC to DC and help protect them from any surges that might occur and cause the LEDs to overheat and become problematic. LED drivers act not only as a current management system but also as a protection buffer.
