什么是边缘发光 LED
一个 边缘发光 LED 是一种 LED 背光显示器或屏幕，利用沿屏幕边缘设置的灯泡提供照明。这种设计可使显示屏变得光滑纤薄，因为 LED 并不直接位于屏幕后面，而是围绕屏幕四周布置。边缘发光 LED 的主要特点是使用 光导这些导光板有助于将灯泡发出的光线均匀地分布在整个屏幕上。这些导光板可确保亮度均匀，防止出现照明不均的区域，从而带来更一致的观看体验。通过将 LED 置于屏幕边缘，光线被引向中心，与其他背光照明方法相比，能产生更柔和的效果。这种设计选择还使显示器更薄，冷却能力更强。

常見問題
哪种 LED 灯泡更亮
因此，将 30 瓦的 LED 灯泡与 30 瓦的白炽灯泡相比，LED 灯泡的光亮度要高得多。事实上，60 瓦的 LED 灯泡可能会亮得让人睁不开眼。这就是我们用流明来衡量 LED 亮度的原因。
何时不使用 LED
LED 灯泡不应在没有适当通风的封闭灯具中使用。这是因为缺乏通风会导致过热，从而大大缩短灯泡的使用寿命。值得注意的是，某些 LED 灯泡的说明书建议不要在封闭的吊扇或全封闭的门廊灯具中使用。
