LED (Light Emitting Diode) lighting has evolved into a pivotal technology in the illumination industry, renowned for its efficiency, durability, and versatility across various applications from home to industrial settings. The inception of LED technology can be traced back to early 20th century discoveries, with significant milestones marked by the creation of the first visible-spectrum LED in 1962 and advancements in blue LEDs during the 1990s. Today, multiple LED types—including miniature, high-power, and RGB LEDs—cater to diverse needs, from decorative lighting to automotive headlights. LEDs are celebrated for their energy efficiency, long lifespan, and eco-friendliness, though challenges like higher initial costs and potential heat sensitivity persist. Their integration into smart home systems and public lighting continues to reshape how we think about illumination.
