LED灯珠发光二极管原理与电性参数
LED是取自Light Emitting Diode三个字的缩写，中文译为“发光二极管”，顾名思义发光二极管是一种可以将电能转化为光能的电子器件，具有二极管的特性。目前不同的发光二极管可以发出从红外到蓝间不同波长的光线，目前发出紫色乃至紫外光的发光二极管也已经诞生。除此之外还有在蓝光LED上涂上荧光粉，将蓝光转化成白光的白光LED。
LED的色彩与工艺：制造LED的材料不同，可以产生具有不同能量的光子，借此可以控制LED所发出光的波长，也就是光谱或颜色。历史上个LED所使用的材料是砷（As）化镓（Ga）,其正向PN结压降（VF，可以理解为点亮或工作电压）为1.424V，发出的光线为红外光谱。另一种常用的LED材料为磷（P）化镓（Ga），其正向PN结压降为2.261V，发出的光线为绿光。
基于这两种材料，早期LED工业运用GaAs1-xPx材枓结构，理论上可以生产从红外光一直到绿光范围内任何波长的LED，下标X代表磷元素取代砷元素的百分比。一般通过PN结压降可以确定LED的波长颜色。其中典型的有GaAs0.6P0.4的红光LED，GaAs0.35P0.65的橙光LED，GaAs0.14P0.86的黃光LED等。由于制造采用了鎵、砷、磷三种元素，所以俗称这些LED为三元素发光管。而GaN（氮化镓）的蓝光LED、GaP的绿光LED和GaAs红外光LED，被称为二元素发光管。而目前的工艺是用混合铝（Al）、钙（Ca）、铟（In）和氮（N）四种元素的AlGaInN的四元素材料制造的四元素LED，可以涵盖所有可见光以及部份紫外光的光谱范围。
LED发光强度：
发光强度的衡量单位有照度单位（勒克司Lux）、光通量单位（流明Lumen）、发光强度单位（烛光 Candlepower）
1CD（烛光）指完全辐射的物体，在白金凝固点温度下，每六十分之一平方厘米面积的发光强度。（以前指直径为2.2厘米，质量为75.5克的鲸油烛，每小时燃烧7.78克，火焰高度为4.5厘米，沿水平方向的发光强度）
1L（流明）指1CD烛光照射在距离为1厘米，面积为1平方厘米的平面上的光通量。
1Lux（勒克司）指1L的光通量均匀地分布在1平方米面积上的照度。
一般主动发光体采用发光强度单位烛光CD，如白炽灯、LED等；反射或穿透型的物体采用光通量单位流明L，如LCD投影机等；而照度单位勒克司Lux，一般用于摄影等领域。三种衡量单位在数值上是等效的，但需要从不同的角度去理解。比如：如果说一部LCD投影机的亮度（光通量）为1600流明，其投影到全反射屏幕的尺寸为60英寸（1平方米），则其照度为1600勒克司，假设其出光口距光源1厘米，出光口面积为1平方厘米，则出光口的发光强度为1600CD。而真正的LCD投影机由于光传播的损耗、反射或透光膜的损耗和光线分布不均匀，亮度将大打折扣，一般有50％的效率就很好了。
实际使用中，光强计算常常采用比较容易测绘的数据单位或变向使用。对于LED显示屏这种主动发光体一般采用CD/平方米作为发光强度单位，并配合观察角度为辅助参数，其等效于屏体表面的照度单位勒克司；将此数值与屏体有效显示面积相乘，得到整个屏体的在视角上的发光强度，假设屏体中每个像素的发光强度在相应空间内恒定，则此数值可被认为也是整个屏体的光通量。一般室外LED显示屏须达到4000CD/平方米以上的亮度才可在日光下有比较理想的显示效果。普通室内LED，大亮度在700～2000CD/平方米左右。
单个LED的发光强度以CD为单位：同时配有视角参数，发光强度与LED的色彩没有关系。单管的发光强度从几个mCD到五千mCD不等。LED生产厂商所给出的发光强度指LED在20mA电流下点亮，视角上及中心位置上发光强度大的点。封装LED时顶部透镜的形状和LED芯片距顶部透镜的位置决定了LED视角和光强分布。一般来说相同的LED视角越大，大发光强度越小，但在整个立体半球面上累计的光通量不变。
当多个LED较紧密规则排放，其发光球面相互叠加，导致整个发光平面发光强度分布比较均匀。在计算显示屏发光强度时，需根据LED视角和LED的排放密度，将厂商提供的大点发光强度值乘以30％～90％不等，作为单管平均发光强度。
LED的发光寿命很长：生产厂家一般都标明为100,000小时以上，实际还应注意LED的亮度衰减周期，如大部分用于汽车尾灯的UR红管点亮十几至几十小时后，亮度就只有原来的一半了。亮度衰减周期与LED生产的材料工艺有很大关系，一般在经济条件许可的情况下应选用亮度衰减较缓慢的四元素LED。
配色、白平衡：白色是红绿蓝三色按亮度比例混合而成，当光线中绿色的亮度为69%，红色的亮度为21％，蓝色的亮度为10％时，混色后人眼感觉到的是纯白色。但LED红绿蓝三色的色品坐标因工艺过程等原因无法达到全色谱的效果，而控制原色包括有偏差的原色的亮度得到白色光，称为配色。
当为全彩色LED显示屏进行配色前，为了达到亮度和的成本，应尽量选择三原色发光强度成大致为3:6:1比例的LED器件组成像素。
白平衡要求三种原色在相同的调灰值下合成的仍旧为纯正的白色。
原色、基色：原色指能合成各种颜色的基本颜色。色光中的原色为红、绿、蓝，下图为光谱表，表中的三个顶点为理想的原色波长。如果原色有偏差，则可合成颜色的区域会减小，光谱表中的三角形会缩小，从视觉角度来看，色彩不仅会有偏差，丰富程度减少。
LED发出的红、绿、蓝光线根据其不同波长特性和大致分为紫红、纯红、橙红、橙、橙黄、黄、黄绿、纯绿、翠绿、蓝绿、纯蓝、蓝紫等，橙红、黄绿、蓝紫色较纯红、纯绿、纯蓝价格上便宜很多。三个原色中绿色为重要，因为绿色占据了白色中69％的亮度，且处于色彩横向排列表的中心。因此在权衡颜色的纯度和价格两者之间的关系时，绿色是着重考虑的对象。
