Do COB LEDs Need Drivers?

In short, COB light source is a kind of high-power integrated surface light source. Its output area and appearance size can be customized according to the specific product structure. We provide customized services and can produce COB products of various shapes and colors according to project requirements. For newly launched COB customization projects, we need to know in detail the key information such as the appearance size, working voltage, color and power of the required COB products.

COB light source, as an integrated chip, also belongs to the category of chips. It requires a special driving power supply to meet its working electrical requirements.

COB LED lamps must be equipped with driving protection devices. First of all, since LED is a temperature-sensitive semiconductor device with negative temperature characteristics, the design purpose of LED driving power supply (also known as driver) is to ensure that LED can maintain a stable working state when in use. Secondly, LED devices have very strict requirements on driving power supply. Unlike ordinary incandescent lamps that can be directly connected to 220V AC mains, LEDs require low-voltage driving and must be equipped with complex conversion circuits. LED light sources for different purposes require different power adapters. A high-quality power supply should comprehensively consider factors such as efficiency conversion, effective power, constant current accuracy, power supply life and electromagnetic compatibility, because the role of the power supply in the entire lighting system is as important as the heart to the human body.

The operation of COB LED is inseparable from the driver, and a stable and constant driver is required to maintain the current. The best way to ensure the stability of COB LED current is to achieve it through a precise driver.
