An LED Driver is an electronic device used to control Light Emitting Diodes (LEDs). The circuit supplies sufficient current to illuminate the LED while limiting the current to prevent damage. The driver can be used to control multiple LEDs simultaneously. Fortunately, there are many different kinds of drivers available today. Light Emitting Diodes drivers are generally classified into two types: those built inside the light fixture, or those that are placed on the surface. The interior type is the most common, as they are generally less expensive. But external drivers are common in downlights and panel lights, among other applications. These two types of Light Emitting Diodes drivers have different functions. Moreover, they are sensitive to voltage and current fluctuations, so an LED driver is necessary to reduce the voltage across LED junctions. LED Driver is used in switched-mode power supplies, which operate by modulating a DC signal in order to produce a predetermined DC voltage. These devices need energy storage in the form of a current or voltage in order to function, and they use inductors and capacitors to store this energy. In addition to the power efficiency of a Light Emitting Diodes driver, another important factor to consider is the power factor. The power factor of a device measures the amount of power it uses compared to the amount of power it actually delivers. When they runs on a higher supply voltage than it needs to power its output, it draws an additional amount of reactive power. This additional power is difficult to measure and is not collected by utility companies. The energy used by a Light Emitting Diodes driver is also higher than the power required by an LED luminaire. Safety is another important factor to consider when choosing a Light Emitting Diodes driver. A good Light Emitting Diodes driver must be able to function in a high-voltage environment without causing interference to nearby equipment. High-quality LED Driver is typically certified by a third party to ensure their safety. Look for certifications such as UL, ENEC, and CB. Light Emitting Diodes drivers can come in either an internal or external design. The latter is typically cheaper and easier to replace than internal drivers. Most LED manufacturers recommend the type of driver that's appropriate for a given light assembly. A good driver should provide constant current and voltage. Light Emitting Diodes drivers can also be programmed using NFC technology. This eliminates the need for an extra wire or cable. Some of these drivers also come with additional programmable functions, such as time dimming and constant lumen output. They may also have an over-temperature protection feature. LED lights can operate at higher powers, but the driver's heat dissipation is also critical. A properly designed driver will draw heat away from thermally sensitive components. Excess heat can affect the reliability of components such as electrolytic capacitors. Moreover, the temperature at which LEDs are used determines how long they will last.
