Mild Electricity is generated when an electron from a greater Power band falls into your reduced energy band and releases Electricity. To paraphrase, when demand carriers electrons and hole brings together, they release light-weight Strength.
plural LEDs : a semiconductor diode that emits light any time a voltage is applied to it and that's made use of specifically in electronic units (as for an indicator light)
因為發光二極管為光源面積小、分佈較集中，作照明用途時會刺眼，須運用光學設計分散光源。
LEDs are throughout us: Inside our phones, our cars and even our residences. Any time anything Digital lights up, there's a superior possibility that an LED is driving it. They can be found in a massive selection of measurements, styles, and colours, but it doesn't matter what they appear like they've got another thing in widespread: they're the bacon of electronics.
