LED Driver and Its Types | led power supply

What is an LED driver?

An LED driver is a self-contained power supplier that regulates the power required by an LED or LED array. Light-emitting diodes are energy-saving lighting devices with long service life and low energy consumption, requiring a dedicated power supply.

How are LED drivers different from convection power supplies?

An LED light driver is like cruise control in a car, requiring different power levels as the LED temperature rises and falls. Without proper LED light drivers, LEDs can overheat and become unstable, leading to failures and poor performance. led pot lights A standalone LED driver must provide constant power to the LED for the LED to work perfectly.

LEDs provide low Voltage and protection for LEDs.

Provides low Voltage

Individual LED lamps to operate at voltages ranging from approximately 1.5 to 3.5 volts and currents up to 30 mA. Household bulbs can consist of multiple bulbs connected in series and parallel and require a total voltage of 12-24 V DC. led pot lights The LED driver rectifies the AC and steps down according to requirements. It converts high AC line voltages from 120 to 277 to the required low DC voltages.

Protect your LED bulbs

LED drivers protect LED lamps from current and voltage fluctuations. The driver ensures that the Voltage and current to the LED lamp stay within the LED’s operating range regardless of major fluctuations. Protection avoids applying too much Voltage and current to affect the LED or too low a current to reduce light output.

LED driver type

LED drivers are used externally or internally within LED lamp assemblies.

Internal LED driver

These are commonly used in home LED bulbs to facilitate bulb replacement. Internal drivers are mostly housed in the same package as the LED.

External LED driver

External drivers are housed distinctly from the LEDs and are typically used for outdoor, commercial, and street lighting applications. led pot lights These lamps require separate drivers and are easy and cheap to replace. In most of these applications, manufacturers specify the type of LED driver for a particular light assembly.

Most LED lamp failures are due to driver failure, and external drivers are easier to replace or repair than internal drivers. What is an LED driver?

Choosing an LED driver

Current and Voltage Modes: LED drivers are either constant current or constant Voltage.

Constant current drivers provide a fixed output current and can have various output voltages. led pot lights A good example of a constant current driver is the one with an output current of 700mA and an output voltage range of 4 to 13V DC.

Constant Voltage LED drivers to provide fixed output voltage and maximum regulated output current. led pot lights They are used in power LED systems that require a stable voltage of, e.g., 12 or 24 volts DC. A typical driver can supply 24V with a maximum output current of 1.04A.

Physical Size: Make sure it fits where it’s fixed.Conclusion

An enclosure’s IP rating indicates the environmental protection provided by the driver’s outer enclosure against the ingress of moisture, dust, other objects, and liquids.

Other factors considered are power factor, maximum wattage, dimming capability, and compliance with international regulatory standards such as UL1310 regarding safety.
