What is driver-free COB LED

COB (Chip-on-Board) LEDs refer to LED packages that contain multiple LED chips within a single module. These LED chips are connected in series and parallel to form a single light source.

The driver is an important part of an LED lighting system because it controls the amount of current flowing to the LED to keep it operating within its rated specifications. Without the driver, the LED may not function effectively and may be damaged. That said, some COB LED products are designed to operate without an external driver. These types of LED modules are often referred to as "driverless" or "AC COB" (alternating current) LEDs. Instead of using an external driver, these LEDs incorporate an internal driver that converts the incoming AC voltage to the proper DC voltage required for the LED chip to operate. This makes them suitable for direct connection to AC power without the need for external drivers.

However, it is important to note that not all COB LEDs are designed to operate without an external driver, and attempting to run a standard COB LED without a driver may result in damage to the LED and may pose a safety hazard. Therefore, it is important to follow the manufacturer's guidelines and specifications when installing and operating LED lighting products.
