LED Bulbs & Modules are solid-state lighting products within the optoelectronics category that generate visible light using light-emitting diodes (LEDs). This classification covers integrated light sources designed to provide illumination through a complete bulb-style assembly or a modular light engine structure.

These products typically combine LED emitters with supporting optical, thermal, and electrical elements to deliver a stable light output as a unified unit.

• LED Bulbs: Self-contained LED-based light sources built as complete lamp units.
• LED Modules: LED-based light source assemblies intended to be integrated into a larger lighting system.
