Selecting the right LED power supply can be a daunting task. The power supply helps in providing the adequate amount of electrical current so the production perform the way they should and they don’t overheat or fail prematurely. It regulates the flow of current to your strip to ensure optimal functionality. One needs to consider various factors for selecting a power supply for LED display products.
As there is constant development of the LED display, there has been noticeable increase in the market share of full-color LED displays. Its high-brightness and high-resolution has been widely favored by marketers and advertisers.
As LEDs have polarity, they work on DC or modulated square wave input, as opposed to conventional light sources that run directly from an alternating current (AC) power supply. When the AC signal is the correct polarity, an LED will only light up about half of the time and will immediately go out when the AC signal is negative bias. For consistent, non-flickering lighting, a constant supply of DC electrical current at a set output or a variable output within a permitted range must be delivered to an LED array.
The type of LED driver you choose is mostly determined by the intended end-use and other constraints. A constant voltage supply can be more cost effective and easier to build for signage and other applications that rely on brilliant or contrasting colours. Furthermore, any hue shifts are usually minor and have no effect on the effectiveness of the observed light. Constant current drivers may be a preferable choice when the intended end-use is illumination. These provide for more consistent light quality and brightness control.
There are factors such as wattage and dimmability that play an important role in determining the power supply that will work for your project.When selecting an LED power supply, you should first consider the wattage requirements of the system as well as your application methods. Directly driving LEDs, driving LEDs with a series resistor, and driving LEDs with a driver IC are the three most prevalent forms of LED driving methods.
One also need to consider location where the supply will be installed and pick a supply with a suitable housing that will be safe to install. There are several types of enclosures with varying IP levels, which decide whether the enclosure cases are dust-tight and capable of withstanding forceful water jets.
Whatever the situation may be, make certain that the power source you choose complies with local safety regulations. Finally, consider whether your application requires output voltage, output current, or dimming capabilities. You might wish to tweak the lighting distribution or change the brightness manually. This is entirely dependent on your specific application.
Certain places additionally necessitate the acquisition of specific safety certificates. Many lighting applications can be disruptive to residential communities or distracting to drivers. Whatever the case may be, make certain that the power supply you select is suitable.
