4. Scientific Explanation of the Light Bulb
4.1 Incandescence
When an electric current passes through a thin filament, the resistance of the material converts electrical energy into heat. As the filament reaches temperatures around 2,500 °C, it emits visible light—a process known as incandescence. The vacuum or inert gas inside the bulb prevents the filament from oxidizing, extending its lifespan That's the whole idea..
4.2 Efficiency and Evolution
Early bulbs converted only about 5 % of electrical energy into visible light, with the rest lost as heat. Over the decades, innovations such as tungsten filaments, halogen gas fills, and phosphor coatings improved efficiency. Modern LED bulbs, while not incandescent, owe their existence to the foundational research sparked by the original light bulb.
