Drivers for LEDs
Pulse width modulation is the main method of operation used in LED drivers. Without it, there would be no flicker-free luminous flux with such a high frequency (100 to 100,000 or more modulations per second). As a result, the LEDs do not lose efficiency, they shine consistently bright, and the voltage and current remain at the same level. Neither the service life, nor the quality characteristics, nor the reliability of led products suffer, and their temperature does not go off the scale. All this makes drivers for LEDs an excellent solution for connecting LED lighting. Those who prefer to buy drivers for LEDs to connect the led devices, get a smooth and efficient operation of the light sources. 220 VAC, converted in the driver, the LEDs come in stabilized and the desired voltage. If not, the LEDs would fail very quickly due to, for example, fluctuations in voltage. The most popular choices of drivers are for 10, 12, 24 V, with a direct current of 350, 700 mA and 1 A. In most cases, the driver goes under a certain product, designed specifically for its needs, but there are universal drivers, the range of which is not limited to a single led product. Drivers for LEDs you can buy as in the sealed housing, and even without housing, if you do not need protection from dust and moisture, where you will apply it. There is also a variant with a non-hermetic housing made of metal or plastic. It is better to buy a special power supply for the led strip. From 300 mA to 700mA is the current strength of those drivers that are designed for high-power LEDs. For them, it is important to provide current stabilization in a narrow range. If the current varies only in a small range, it significantly prolongs the "life" of the LED and it works bright and stable. When installing them, a heat sink is mandatory. Various control systems, as well as sensors of photocells and drivers for LEDs work well together, they have full compatibility, they can be placed in one junction box. The driver can change the shade of the LED glow and its brightness, due to the fact that you reduce the current through it.
