Types of COB LED Driver

According to the LED driver, LED lighting, especially COB lighting, is becoming easier to use. An LED driver is a device that provides the required power for one or more LED lights. They are essential for LED lighting, and their use is expected to increase as LED lighting becomes more popular.

COB LED lights are made up of multiple tiny chips mounted on a single board. The light is brighter than other LED lights because it provides a higher lumens output. A COB LED driver is needed to power these lights. It provides a constant current that powers the LED lights and increases their efficiency.

The LED drivers come in different forms and configurations. Here are some of them:

  • Linear LED drivers

    A linear COB LED driver is known for its simplicity and low cost. It is mostly used for low-power lighting applications. The driver provides a constant voltage or current to the LED lights. It is efficient and has low ripple voltage. However, it is not suitable for large-scale lighting projects because it has a low output power.

  • Switching LED drivers

    The switching LED driver is more advanced than the linear driver. It is also more expensive and uses a switching regulator to provide power to the LED lights. The driver is divided into several types, including boost, buck, and buck-boost switching drivers. The drivers are suitable for high-power lighting applications and have a high efficiency of about 90%.

  • Isolated LED drivers

    This driver uses electromagnetic induction to transfer power from the source to the LED lights. It has a high level of efficiency and is suitable for high-power lighting applications. The driver also provides electrical isolation, which increases the safety and reliability of the lighting system.

  • Non-isolated drivers

    A non-isolated driver does not provide electrical isolation. It transfers power using a direct connection. The driver is cheaper than the isolated driver, but it has low efficiency. It is mostly used in low-power LED light applications.

  • High-frequency drivers

    These drivers use high-frequency switching techniques to control the output current. They are more compact and have more efficiency. However, they can cause electromagnetic interference in some lighting systems.

  • Thermal LED drivers

    These drivers control the LED light's output current by measuring its temperature. They are useful when the LED lights overheat because they can automatically reduce the current and temperature.

Function and feature of cob led driver

The LED driver for COB lights has special features for controlling and driving LEDs. They include the following:

  • Constant Current Output

    The driver has output current stability. The output current doesn't change with changes in LED forward voltage or temperature. This stability maximizes LED brightness and minimizes thermal damage. The LEDs have a longer lifespan because of this constant current output.

  • High Efficiency

    The efficiency of the LED driver is between 85% and 95%. The efficient power conversion lowers energy costs for customers. Low operating expenses are attractive to businesses that want to save money. The high efficiency of the driver also means little heat is lost. Reduced heat means the driver can work at higher power levels without overheating.

  • Dimmable Output

    Some LED drivers have dimming capabilities. They support 1-10V dimming and PWM dimming. The dimming feature allows the users to change the brightness levels according to their needs. Dimming the brightness saves energy. The driver also has a constant current output. The dimming feature is essential for applications that need different brightness levels, such as office lighting.

  • Thermal Protection

    The driver has a built-in thermal protection mechanism. It monitors the temperature and reduces the output current during high temperatures. If the temperature gets too high, the driver will shut down automatically. This protection prevents overheating and hardware damage.

  • Multiple Output Channels

    The driver can have multiple output channels. It can drive up to 8 channels. The channels allow one driver to power different LED strings. It provides a stable current for each string.

  • Wide Input Voltage Range

    The drivers can accept different input voltages. They work with voltage levels from 100V to 300V. Some drivers accept voltages from 20V to 60V. The wide input voltage range makes the drivers versatile. They can be used in different global locations with different voltage requirements.

  • Efficiency and Heat Dissipation

    To prevent overheating, a driver with high efficiency should be chosen. This is because it will produce less heat.

  • Compatibility and Integration

    For easy integration, the LED driver should be compatible with the existing lighting control system. Also, it should be compatible with other lighting components.

  • Protection Features

    To enhance the durability of the lighting system, a driver with protection features should be considered. Such as; short circuit, over-voltage and over-temperature protection.
