关于  LED 指示 - 分立

发光二极管(LED)是半导体器件,当电流通过它们时会发出光。这些LED通常以单个或阵列的形式用于指示印刷电路板的状态。 LED可以根据不同的参数进行区分,如封装/外壳类型、波长、视角、正向电压、电流额定值、亮度(以毫坎德拉为单位)、颜色和安装类型。封装/外壳类型指的是LED的物理形式,可以从小型表面贴装封装到较大的插件封装。 波长是定义LED发出的光的颜色的关键参数。LED发出的波长范围决定了其颜色,常见的颜色包括红色、绿色、蓝色、黄色和白色。 视角是指发出的光可见的角度范围,可以从几度到超过180度不等。正向电压是LED正常工作所需的电压,电流额定值是LED可以通过的最大电流,超过该值可能会损坏LED。 亮度以毫坎德拉为单位表示LED的亮度,通常范围从几毫坎德拉到几百毫坎德拉不等。安装类型可以从表面贴装到插件式,可以提供共阳极、共阴极或双向配置。 总的来说,这些参数使工程师和设计师能够为特定应用选择合适的LED。无论是用于指示印刷电路板状态、照明显示器还是提供背光,LED都提供了一种多功能和高效的解决方案,能够精确控制照明特性。
