1. Overview

LED lamp replacements represent a transformative advancement in solid-state lighting technology. These semiconductor devices directly convert electrical energy into light through electroluminescence, offering superior energy efficiency (>80% reduction vs traditional lamps), extended operational lifespan (25,000-50,000 hours), and environmental benefits. Their importance in modern applications spans from residential lighting to specialized industrial systems, driven by global energy efficiency standards and smart lighting integration requirements.
