LED Power Supplies

LED drivers for LED lamps and lighting fixtures.

There are a lot of myths about LED power supplies. Ideas about them are divided into two conditional categories: about the instability of these devices and their reliability. The truth about them, as always, is somewhere in the middle. The era of lamps that quickly failed has passed. Now you can buy a reliable and affordable LED lamp of any glow color in a store.

An LED power supply is an electrical necessity. LEDs do not operate on standard alternating current. For power supply, voltage converters with stabilized current are needed – drivers for LEDs. LED power supplies are an important electronic component of any lamp, can be installed separately from the LED backlight.

The driver for LEDs requires the same service as other AC / DC voltage converters. When operating in a power grid, it often breaks down, but this is not critical if the manufacturer provides a warranty and can repair the driver.

Driver for LED strips and LED modules.

A driver is a device that converts AC voltage into DC voltage. A classic power supply or driver for an LED lamp is designed to supply LEDs with current. Also know DC-DC converters used to decrease supplying LED current, when you have a small group of diodes.

Only current stabilizers with the appropriate parameters and characteristics are suitable for reliable and long-term use of LED lamps. When choosing an LED driver, you should take know the voltage drop on the module and the maximum permissible current of the LED.

The driver is needed to produce a stable current, ensuring the operation of your lamps for the entire period. The marking of lamps contains a parameter of 50000 hours of operation, but they are possible only under conditions of correctly calculated current.

Criteria for choosing a power supply for LEDs.

It is easy to choose a power supply, it essentially has two parameters for a customer: current and voltage. With drivers, everything is more complicated. They are divided into two relatively large groups: “unlimited” (within the total power) and for a certain number of diodes.

A power supply is selected according to the marking on your lamp. The driver should be selected carefully. In order for your lamps to work longer, it is better to buy a set of a driver and LED module. You can also buy them separately, but in this case the service life of the LED strip is changing.

When buying a set of equipment, customers often confuse the current parameters. The point is in the correct assessment of the operating range. If the LED is marked 500 mA, this is the maximum current for which it is designed. In fact, you need to take a driver with slightly lower parameters, with a current in the range from 300 to 350 mA.

Functional features of power supplies and LED drivers.

LED drivers may differ:

• non-isolated or with galvanic isolation;
• by circuit design (single- and double- stage);
• by stabilization (current or voltage);
• with active or passive power corrector;
• by IP protection rating (sealed or non-sealed).

The main rule when choosing an LED driver or LED power supply is to have a reserve of 15-20 percent of its rated power when using it in a lamp.

Where to buy a power supply for LEDs.

You can buy a high-quality power supply for LEDs or an LED driver for a strip from the manufacturer in the online store LRC.
