Funny fails| Fights | comedy 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

David Anzola | The Bilingual Dad on Instagram: "Three years since that little cucaracha 🪳 video of my son took off… over 60 million views later and it still blows my mind. Since then, my kids have gotten amazing opportunities, brand deals, and experiences I never could’ve imagined for them. And somewhere along the way, I found a passion I didn’t know I had.. Teaching parents how to pass down their language from home has become one of my favorite parts of this journey. I know I’ve been a

Aeonmaxx on Instagram: "日本利用壓電磁磚將腳步轉化為電能。這些瓷磚能夠捕捉您行走時的動能。行走時，您的體重和運動會對瓷磚施加壓力，使其輕微彎曲並產生機械應力。磁磚內部的壓電材料會將這種應力轉化為電能。每走一步都會產生少量電荷，數百萬步累積的電荷足以驅動LED燈、數位顯示器和感測器。在澀谷站等繁忙區域，每天約有240萬人次的腳步為該系統供電。這些電能可以儲存或立即使用，從而降低能源消耗。 這種方法減少了對傳統能源的依賴，並支持永續的城市基礎設施建設。它將日常活動轉化為實用的可再生能源。日本利用壓電磁磚。這些瓷磚能夠捕捉您行走時的動能。行走時，您的體重和運動會對瓷磚施加壓力。磁磚輕微彎曲並產生機械應力。磁磚內部的壓電材料會將這種應力轉化為電能。每走一步都會產生少量電荷，數百萬步累積起來的電量足以驅動LED燈、數位顯示器和感測器。在澀谷站等繁忙區域，大約2400萬步就能產生足夠的電力。 這些電力可以儲存或立即使用，從而減少對傳統能源的依賴，並支持可持續的城市基礎設施建設。這種方法將日常活動轉化為實用的再生能源。日本使用壓電磚。這些磚塊可以捕捉你行走時的動能。當你行走時
