KarmaSutra 🪭 on Instagram: "✨ LED 是怎麼發光的？比你想的更神奇！ ✨ ⠀ 在我們的生活裡，LED 幾乎無所不在——手機螢幕、汽車大燈、指示燈、家裡的氛圍燈…但你知道這些小小的光點究竟是怎麼亮起來的嗎？ ⠀ 其實，LED（發光二極體）的核心原理非常精妙： 它利用「半導體材料」之間的能量差，在電子移動的瞬間釋放出光。 ⠀ 想像一下，有兩邊地形不同的山谷。一側是充滿電子的「N 型材料」，另一側是缺少電子、需要補位的「P 型材料」。 當電流通過時，電子就像從高處跳入低處的能量谷底，而每一次跳躍，都會釋放出一個微小的光子。 ⠀ 🌈 光的顏色由什麼決定？ LED 的顏色不是靠染料，也不是玻璃，而是取決於半導體本身的材料與能隙大小。 能量差越大，光的頻率越高、顏色越偏藍；能量差越小，光的顏色就越偏紅。 這也是為什麼 LED 可以做成各種顏色，甚至組合成白光。 ⠀ 💡 為什麼 LED 那麼省電？ 因為大部分的能量都直接轉成光，而不是熱。 不像傳統燈泡那樣先把燈絲燒得超級熱，再間接產生光，LED 幾乎沒有浪費。 ⠀ 🔧 小小結構，大大力量 LED 的體積可以非常

Factsdailyy on Instagram: "A driver in a stolen Jaguar F Type led officers on a wild chase across Los Angeles before slipping out of sight. The pursuit reached high speeds on the I10, which forced police to pull back for safety. A helicopter kept watch, but the suspect made a clever move by turning onto the I110 and stopping under an overpass. He jumped out while the car kept rolling forward on its own. The empty Jaguar drifted ahead and eventually hit a pole, while the suspect disappeared into
