What is an LED?_ An LED (Light Emitting Diode) is a type of semiconductor device that converts electrical energy into light. _How does it work?— When a voltage is applied to the LED, electrons recombine with holes, releasing energy in the form of photons, which we see as light. _Key Characteristics:_ ���_Color_: LEDs are available in a range of colors, including red, orange, yellow, green, blue, and white. ��_Brightness_: Measured in lumens (Im) or candelas ���_Voltage_: Typically operate betwee

Kylo Ren on Instagram: "本利用压电瓷砖将脚步转化为电能。这些瓷砖捕捉来自你脚步的动能。当你行走时，你的重量和动作会对瓷砖产生压力。瓷砖会轻微弯曲，从而产生机械应力。瓷砖内部的压电材料将这种应力转化为电能。每一步都会产生少量电荷，而数百万步结合在一起就能产生足够的电力来驱动LED 灯、数字显示屏和传感器。在像涩谷车站这样繁忙的地方，每天大约有240万个脚步为这一系统作出贡献。这些电能可以被储存或立即使用，从而减少对传统电力来源的依赖，并支持可持续的城市基础设施。这种方法将日常运动转化为实用的可再生能源 ＃日本 #知识＃事实 #你知道吗＃推荐#科技 #创新 #历史技术实验热门"
