A LED module is a compact unit that contains one or more light-emitting diodes (LEDs) along with necessary circuitry to power and control them. LED modules are designed to simplify the process of integrating LED lighting into various applications by providing a ready-to-use, self-contained lighting solution.

Here’s a quick rundown of what you might find in an LED module:

1. LEDs: The light-emitting diodes themselves, which produce light when an electric current passes through them.

2. Driver Circuitry: Components that regulate the power supplied to the LEDs to ensure they operate correctly and efficiently.

3. Heat Sink: In some modules, there’s a heat sink to dissipate heat generated by the LEDs, which helps prolong their lifespan and maintain performance.

4. Mounting Hardware: Some modules come with built-in mounting options or clips to facilitate installation.

5. Optics: Lenses or diffusers may be included to shape or soften the light output.

LED modules are used in a wide range of applications, from residential and commercial lighting to backlighting for displays and signage. They are valued for their energy efficiency, long lifespan, and flexibility in design.
