மின்விளக்கின் சரித்திரம் | The Rise and Fall of the Incandescent Light Bulb

Before LEDs and smart lighting transformed our homes, one invention illuminated the modern world for over a century — the incandescent light bulb.

In this video, we explore the fascinating history, science, and eventual decline of incandescent lighting. Discover how inventors like Thomas Edison and Joseph Swan revolutionized electricity by creating practical commercial light bulbs that changed human civilization forever.

Learn how a tiny tungsten filament inside a glass bulb produces light through intense heat, why early bulbs used carbon filaments, and how inert gases improved lifespan and performance. We also uncover the major problem with incandescent bulbs: most of their energy is wasted as heat instead of visible light.

As governments around the world pushed for energy efficiency, incandescent lamps slowly disappeared, making way for modern alternatives like LEDs and compact fluorescents.
