LED Lighting - COBs, Engines, Modules

LED lighting has revolutionized the way businesses, offices and consumers are able to light their spaces. COBs, engines and modules are among the most important components of LED lighting, and knowledge of their application field and working principle can help one make the most of the wide range of LED lighting products.

LED COBs

COBs, or “Chip-on-Board” arrays, are one of the most efficient and durable lighting solutions available for LED lighting. They are small semiconductor packages typically containing a number of LED chips, or die, on a single substrate that can be up to four times more efficient than traditional LED chips. COBs also have a higher power-density than solid-state LED chipsets and are generally easier to install and use.In terms of application field, COBs are mainly used in large-scale lighting initiatives. They are often used in the automotive sector, to light up signage, in high-end entertainment lighting and in the production of architectural lighting. In general, COBs are capable of producing higher intensity output over a wider range of wattages and beam angles than traditional LED chips.The working principle of LED COBs is relatively straightforward. LED chips, or die, are mounted on a substrate and then connected to voltage, current and temperature controllers, along with a heat sink. This forms a single lighting component, a COB, which then routes the electrical power through its internal conductors to the LED chips and, in turn, produces light. COBs can be controlled on an individual basis or in combination with other COBs.

LED Engines

LED engines are similar in concept to COBs but are more focused on achieving efficient and longevity from a single component component. Whereas COBs are made from multiple die, or chips, and are connected to controllers and a heat sink for heat dissipation purposes, LED engines are purpose-built components, meaning they have all the necessary electrical and mechanical components to light up a space in one unit.In terms of application field, LED engines are most often used in spotlight applications, and are increasingly being used in new construction and renovation projects due to their energy efficiency, durability, and uniform light distribution.LED engines work by converting the electrical power they receive into light, while also dissipating the heat created during the process. This is done through the combination of a heat sink, which manages and dissipates the heat, and a driver, which converts electrical power into a manageable current. The light produced is then routed through the engine’s PCB and lens, and shines outward, lighting up whatever space it is placed in.

LED Modules

LED modules are something of a hybrid between COBs and engines, in that they are a combination of a number of components, typically including a driver and a lens. Though they are usually more expensive and require more technical knowledge to install than COBs and engines, LED modules are popular due to their versatility, as they can be used to create a wide range of lighting effects.In terms of application field, LED modules are most commonly used in commercial buildings, office environments and public spaces, as they are highly energy efficient, durable, and easily customizable.The working principle of LED modules is quite simple; just like with COBs and engines, LED modules convert electrical power into light. The modules also heat up during use, which is why most LED modules come with a built-in heat sink and are typically supplemented with a driver for maximum efficiency. The light created is then dispersed through a lens, which directs it outwards, to light up whatever space it is installed in.

Conclusion

While LED lighting is a relatively new technology, the wide range of components available for it are quickly becoming essential for home, business and entertainment lighting applications. COBs, engines and modules are just three of the many components used in LED lighting; knowledge of their application field and working principle can help one make the most of LED lighting and its capabilities.
