🔦 LED vs. Halogen: How Do They Light Up? 🔦 In this video, we explain the light emission principles of two popular car lights: LED and Halogen. 💡 🎥 LED Headlights: LEDs generate light through semiconductor materials. When current flows, electrons and holes combine, releasing energy in the form of light. High Efficiency: Most of the electrical energy is converted into light, with very little heat produced. Long Lifespan: LED headlights provide consistent brightness for a long time. 🎥 Halogen
