el817工作原理
el817工作原理
EL817是一款光电耦合器，也被称为Optocoupler或光耦，常
用于电气隔离和信号传输。
EL817工作原理如下：
1. 光发射器：EL817的光发射器由发光二极管（LED）构成。
当LED接收到输入电流时，它会发出光信号。
2. 光接收器：光接收器由一个光敏三极管（Phototransistor）
组成。
当光信号照射到光敏三极管时，它的发射电流会改变。
3. 输入端和输出端电气隔离：通过内部结构设计，LED和光
敏三极管之间没有直接的电气联系。
这种隔离设计可以有效防止输入和输出之间的电流泄露，从而提高系统的安全性和可靠性。
4. 光电转换：当输入电流通过LED时，它会产生光信号。
这
个光信号以脉冲的形式传播到光敏三极管。
光敏三极管根据光信号的强弱转换为相应的电流，进而输出一个对应的电信号。
5. 信号传输：光敏三极管的电流输出端可以连接到其他电路中，用于传输光电转换后的信号。
通过光耦的工作原理，输入电路和输出电路之间实现了电气隔离，避免了潜在的干扰和噪声。
总结：EL817的工作原理基于光电耦合效应，利用LED发出
的光信号，通过光敏三极管的光电转换，实现输入和输出之间的隔离和信号传输。
这种工作原理使得EL817在电气隔离和
信号传输方面具有广泛的应用价值。

光耦el817的工作原理
光耦el817的工作原理光耦（Optocoupler）是一种常用的光电器件，也称为光电隔离器或光电耦合器。
其中，EL817是一种常见的光耦型号，被广泛应用于电子设备中。
本文将从工作原理角度解析EL817的原理及其应用。
一、EL817的结构EL817主要由一个发光二极管（LED）和一个光敏三极管（光电晶体管）组成。
其中，LED作为输入端，当输入电流加到LED正极时，LED发出的光线会照射到光敏三极管的基极上，进而激活光敏三极管的发射结。
二、EL817的工作原理EL817的工作原理基于光电效应。
当输入电流加到LED正极时，LED发出的光线会照射到光敏三极管的基极上，光线的能量被吸收后会激活光敏三极管的发射结，形成电流的传导。
这个过程实现了输入信号的光电转换。
具体来说，当LED发出的光线照射到光敏三极管的基极上时，光敏三极管的发射结会受到光线的激发，使得发射结的电流得以流动。
这个电流被称为输出电流，它与输入电流之间存在一定的线性关系。
因此，EL817可以实现输入与输出之间的电隔离与信号转换。
三、EL817的应用由于EL817具有电隔离、信号转换等特点，因此在许多电子设备中得到广泛应用。
1. 电隔离EL817能够实现输入与输出之间的电隔离，从而保护输入与输出之间的电路不受干扰。
例如，在测量仪器中，输入端可能需要测量高压信号，而输出端则需要连接低压电路，这时就可以使用EL817实现输入与输出之间的电隔离，确保安全可靠的信号传输。
2. 信号转换EL817能够将输入信号转换为输出信号，实现不同电平之间的信号匹配。
例如，在数字电路与模拟电路之间，由于电平差异，可能需要使用EL817将数字信号转换为模拟信号，或者将模拟信号转换为数字信号，以实现两者之间的互联互通。
3. 电噪声隔离在一些噪声环境下，输入信号可能会受到电磁干扰或其他干扰源的影响，导致输出信号质量下降。
EL817能够通过电隔离的特性，将输入信号与输出信号隔离开来，从而减少噪声的传递和影响，提高信号的纯净度。

长条形光斑 光电开关-概述说明以及解释
长条形光斑光电开关-概述说明以及解释1.引言1.1 概述概述长条形光斑是指在光电开关中产生的一种特殊形状的光斑。
光电开关是一种通过光电传感技术实现物体检测和触发操作的装置。
它利用光源射出的光线与物体发生反射或透射，通过接收器接收到的光信号来判断物体的存在与否。
长条形光斑作为光电开关的重要组成部分，具有独特的特点和广泛的应用。
在光电开关中，长条形光斑通过透镜等光学元件将光源发出的光束聚焦成一条长条形的光斑。
这种光斑形状的设计使得光电开关在探测物体时具有更高的精度和敏感度。
长条形光斑可以提供更多的信息，例如物体的位置、方向和运动速度等。
此外，长条形光斑还可以通过调节聚焦距离和光斑宽度来适应不同场景下的需求。
光电开关中的长条形光斑具有许多应用。
首先，它可以用于物体的检测和触发操作。
当物体经过光斑时，光电开关会接收到变化的光信号，从而触发相应的操作，如打开或关闭电路。
其次，长条形光斑还可以用于测量物体的距离和位置。
通过计算光电开关接收到的光信号的强度和时间差，可以准确地计算出物体相对于光电开关的位置。
此外，长条形光斑还可以应用于工业自动化领域，用于检测物体的旋转和运动轨迹。
综上所述，长条形光斑作为光电开关的重要组成部分，在物体检测和触发操作中具有广泛的应用前景。
通过光传感技术的不断发展和改进，长条形光斑在未来的发展中将发挥越来越重要的作用，并为各行各业带来更多的便利和效益。

亿光 ALS-DPDIC17-78C L749 TR8 数位环境光感应器应用手册说明书
数位环境光感应器ALS-DPDIC17-78C/L749/TR8应用手册一、简介：环境光感应器(Ambient light sensor; ALS)可以感测到和人眼接收感觉类似的光源，并让相关的应用产品根据感测到的光源资讯做相应的开，关及自动调整控制，以达到省电及安全的应用目的。
类比环境光感应器靠调整负载电阻来改变切换门槛值且精确度较差，微处理器(MCU)可经由I2C介面对数位ALS的暂存器做读、写控制，借此达到较准确的控制。
而亿光的ALS-DPDIC17-78C/L749/TR8数位环境光感测器，因封装内有两组不同频谱的光二极体(PD)感测元件，故可区分出不同的光源，以达到更高的准确度。
二、机构开孔建议：不管是在室内或室外使用ALS，环境光通常都是从上方或是斜上方照下。
故会建议开孔的方向朝上为最佳，朝前次之，尽量让环境光直接照射到ALS，一般来说较高的进光量可以得到较高的精确度也可加快量测速度，但须注意若在中午太阳光直射的情况下有可能会造成ALS饱和。
有些时候为了ID设计美观会让开孔朝下，利用反射方式侦测环境光，但此种方式会受到反射物的反射率影响造成ALS的准确度下降。
底下图一是开孔朝上的建议开孔方式。
图一、朝上开孔建议基于进光量的考量●θ1建议大于35°且D1建议小于2.6mm。
●可参考建议开孔公式DLENS= tanθ1 x D1 x 2 + Package Width。
●假设D1= 1mm, θ1= 35°，则DLENS= tan35° x 1mm x 2 + 2.0 =3.4mm。
●增加开孔大小或是缩短D1的距离都可以增加进光量，使ALS量测更准确。
若开孔是朝前方的话，由于环境光多由斜上方照射，故可参考底下图二，在同样开孔大小下，让θ1的角度大于θ2。
图二、朝前开孔建议一般ID设计不会想让使用者直接看到ALS，所以通常会在ALS上方加半透明的cover lens，Lens透光度越高越好，最好不要低于30%。

el817c光耦工作原理
el817c光耦工作原理
EL817C光耦工作原理是通过将一个发光二极管和一个光敏三极管封装在一个光学隔离材料中，实现输入信号和输出信号的电气隔离。
当输入信号电压施加在发光二极管的正极和负极之间时，发光二极管会发出红外光。
这个红外光会经过光学隔离材料中的隔离通道，进一步照射到光敏三极管上。
光敏三极管通过其感光面上的敏感介质吸收红外光，引起内部电流的变化。
这个电流的变化与输入信号电压的变化有关。
当红外光较强时，光敏三极管的电流也较大；当红外光较弱或没有时，光敏三极管的电流较小或为零。
通过测量光敏三极管输出的电流变化，即可获得输入信号的信息。
由于光耦组件将输入信号和输出信号电气隔离，因此可以避免输入信号的电压或电流对输出电路的干扰。
这种光电隔离的工作原理使EL817C光耦能广泛应用于电气隔离、噪声屏蔽、信号隔离等领域。
