LED Lighting - COBs, Engines, Modules

Light-emitting diode (LED) lighting is quickly becoming the industry standard for lighting applications, providing energy-efficient, environmentally responsible illumination. Within the space of LED lighting are three main components: chip-on-board (COB) arrays, engines, and modules. Each has its own particular use and working principle, making it important for designers and engineers to understand the technology and application of them.

Chip-on-Board Arrays

Chip-on-board (COB) arrays are comprised of multiple light emitting diodes (LEDs) arranged onto a substrate and connected to each other with very little electrical circuitry. This technology allows for more LED sources to be placed into a smaller area for a more optimized, efficient illumination design. While the number of LED light sources used in a single COB array varies, typically 10 to 40 individual LED dies are used and paired with a single driver or power source. COB arrays require a single current source and arrangement of leads, allowing for individual dies to be connected in parallel rather than series, like most traditional LED designs. This arrangement reduces the total system cost and complexity while providing increased energy efficiency and flexibility in design as each LED source can be individually positioned, allowing for a variety of different shapes and optic outputs.

Engines

LED Engines are composed of 2 or more LED components. This might include COBs, mid-power LEDs, or high-power LEDs. By combining multiple components into a single package, the design complexity and cost reduces significantly. Engines can provide the same light output as individual components, but require less space for assembly. Engines provide designers with additional versatility and flexibility, allowing for more complex light designs with fewer components. When paired with a single driver or power source, the engines also provide enhanced power efficiency and thermal management. This helps reduce the total system cost and improve the overall performance. Additionally, by providing a single current source, engineers have increased power and load regulation, providing more consistent illumination across the application.

Modules

Modules are the most common type of discrete LED components. A module consists of a single LED, usually supported in place by an ultimate heatsink base. Modules requires its own dedicated driver, providing a single source of power and allowing for easier installation than multiple components. In addition, modules provide a more comprehensive range of brightness and color temperatures than COB arrays and engines, giving designers and engineers more freedom to create effective lighting solutions. Modules may also provide more design flexibility as they require less space and wiring than COBs, as well as are often available in different package sizes.

Conclusion

In conclusion, understanding the application field and working principle of COB arrays, engines, and modules is essential when it comes to designing effective and efficient LED lighting solutions. By leveraging the technology of these components, designers and engineers can create advanced lighting systems with greater energy efficiency and performance, while reducing cost and design complexity.
