What is the difference between LED engine and LED module?

The terms "LED engine" and "LED module" are often used interchangeably in the lighting industry, but they refer to slightly different components with distinct functions.

An LED engine typically refers to a complete lighting system that incorporates not only the LED light source but also the necessary driver, optics, thermal management, and other components required for operation.

LED engines are often designed as integrated units, where all the components are housed within a single assembly. This includes the LED chips, phosphor coating (for white light), lenses or reflectors for beam shaping, heat sinks for thermal management, and the LED driver for regulating power to the LEDs.

LED engines are usually designed for specific lighting applications, such as downlights, track lights, or outdoor luminaires. They offer a convenient and efficient solution for lighting manufacturers, as they can be easily integrated into lighting fixtures without the need for additional components.

LED engines are often considered the "heart" of LED lighting systems, providing the primary light source and driving electronics in a compact and easily deployable package.

An LED module typically refers to a smaller subcomponent of an LED lighting system, often consisting of just the LED chips mounted on a printed circuit board (PCB) with minimal additional components.

LED modules are designed to be more modular and customizable compared to LED engines. They may lack integrated drivers or optics, allowing for greater flexibility in designing lighting fixtures with specific beam angles, color temperatures, or dimming capabilities.

LED modules are commonly used in applications where custom lighting solutions are required, such as architectural lighting, signage, and retrofit projects. They can be easily combined or arranged in different configurations to achieve the desired lighting effects or performance characteristics.

While LED modules offer flexibility and customization options, they may require additional components, such as drivers, lenses, or heat sinks, to be integrated into a complete lighting fixture.

In summary, the main difference between an LED engine and an LED module lies in the level of integration and completeness of the lighting system. LED engines are self-contained units that include all the necessary components for operation, while LED modules are smaller subcomponents that may require additional components to be integrated into a complete lighting fixture.
