LED Lighting - COBs, Engines, Modules

LED lighting is a rapidly growing market, and it relies on three core components, which include chip-on-board (COB) lighting, lighting engines, and lighting modules. In many cases, the three can coordinate in a unit to power the LED lighting, but they each have their own distinct purpose and working principle. In this article, we will be discussing the application field and working principle of each type.

COBs

COBs, which stands for Chip-on-Board, are light sources that contain multiple light-emitting diodes (LEDs) built into a single board, enabling the lighting to be tuned and enhanced in different ways. This makes them a great choice for many commercial and residential applications, and they are often used in ceiling and lighting fixtures due to their energy-saving capabilities.

In terms of working principles, COBs are made up of an array of LEDs that are connected directly to a power supply. Each LED has its own output, which produces a direct current, and this current is then regulated in order to provide the correct levels of brightness and voltage. This direct current provides a more reliable, consistent illumination than other forms of lighting.

Engines

When it comes to LED lighting, the engine is the device that powers the lighting. It provides the necessary power and current to the LED, providing a consistent, long-lasting illumination that is tailored to the user’s needs. Engines can range in sizes, but they all share the same characteristics – making them an important component in LED lighting.

In terms of working principles, LED engines work similarly to COBs, except they have a much lower current draw than COBs. This makes them more efficient while allowing them to produce the same levels of brightness and voltage. LED engines are usually connected to a power source, and once connected, they will regulate the current and voltage in order to provide the desired level of brightness.

Modules

Modules are components of LED lighting that are designed to offer additional features and functions. These can include dimming, color changing capabilities, as well as additional wattages and voltages. Modules can be connected to either COBs or LED engines and can provide additional functionality and features to enhance the user experience.

In terms of working principles, LED modules are designed to regulate the current and voltage in order to provide optimal levels of brightness and color accuracy. They are self-regulating and can be connected to either COBs or LED engines to provide additional features, such as dimming or color changing capabilities. Modules are also able to monitor power consumption and provide feedback in order to ensure efficient operation.

Conclusion

COBs, engines, and modules are the three main components of LED lighting and they each have their own distinct purposes and working principles. COBs are light sources that contain multiple LEDs and are used for a range of commercial and residential applications. Engines are the devices that power the lighting and provide a consistent, long-lasting illumination. Lastly, modules are designed to offer additional features and functions, such as dimming and color changing capabilities.
