由Alexa提供支持的Amazon Echo 智能扬声器(Amazon Echo smart speakers)是金钱可以买到的最好的智能扬声器。它们听起来很棒，工作良好并且非常可靠。但是，有时事情可能会出错。
由于您的Echo扬声器没有屏幕，因此它使用光环来提供视觉反馈。即使是配备屏幕的Echo Show有一个小光带也使用这种反馈方式。
灯光(Light)代码原则上很好，但如果你不知道灯光的含义，那只不过是看起来很漂亮的东西。好消息是这些光代码并不多，而且它们中的大多数都具有相当良性的含义。
光在哪里？
本文中的颜色代码专门指在各种型号的Amazon Echo扬声器顶部的LED环。(LED)这个小环形灯可以改变它的颜色和闪烁模式。
它甚至可以改变环的离散部分的颜色。凭借这个光阵列，亚马逊(Amazon)已经成功地将数量惊人的信息打包到系统中。
您可以直接询问 Alexa
亚马逊(Amazon)知道，实际上很少有人会仔细阅读他们的Echo扬声器手册。这(Which)就是为什么你可以简单地问Alexa“你的灯是什么意思？” 她会告诉你的。
也许我们应该等到文章结尾再告诉你，但要坚持到最后，因为Alexa并不总是能够说话，所以提前通过视觉了解这些光是值得的。
几秒钟后(Few Seconds Apart)缓慢的黄色爆发(Slow Yellow Burst)
这个缓慢的、脉动的黄色圆圈可能看起来像是某种错误，但实际上并不严重。
这意味着有通知或消息等待您的注意。您所要做的就是询问Alexa您的通知或消息是什么，她会告诉您。
希望(Hopefully)这不是关于你妈妈生日的提醒。
青色(Cyan)截面上的蓝色环(Blue Ring)
使用此光代码，带有青色尖端的蓝色圆圈会射出，在环的另一端相遇。这可能是任何拥有Echo的人都会看到的最常见的灯光代码。
那是因为这意味着Alexa正在倾听。当Alexa思考一个诙谐的反驳时，灯光会闪烁以表示确认。
一个纯红色的戒指
虽然旧Xbox 360(Xbox 360)上的红色环表示Echo扬声器上的“惊喜，你必须购买新的Xbox ”，但它仅表示麦克风已静音且Alexa没有在听。如果您使用的是带有摄像头的Echo设备，这也意味着摄像头不会记录您。
如果您想让Alexa听到您的声音，您必须按下Echo上的专用静音按钮，红色环应该会关闭，这表明Alexa现在已准备好听到您的请求。
旋转蓝环
如果您看到旋转的蓝色和青色环，则表示您的Echo设备正在启动。如果一切正常，环会闪烁青蓝色，然后关闭。如果这是第一次打开Echo或已重置，则指示灯将变为橙色。
黑色上旋转的橙色部分
如果您看到此信息，则表示您的Echo处于初始设置模式。它将首先尝试连接到互联网，然后继续进行所需的所有内务管理，其中可能包括下载更新。
它需要您的帮助才能使用Alexa应用程序进行连接。如果您在设置方面需要帮助，请查看开始使用您的新 Amazon Echo(Getting Started with Your New Amazon Echo)以获得动手演练。
脉动的绿色
如果您看到闪烁的绿灯，恭喜！这意味着有一个来电，有人想和你说话。接听电话后，铃声将变为旋转的绿灯。因此，请继续说“ Alexa接听电话”以找出谁想与您聊天。
紫色闪光
对于已设置的Amazon Echo，在您向Alexa询问任何内容后，紫色的短暂闪烁意味着您已打开请勿打扰模式。(Disturb Mode)这是一个方便的提醒，因为很容易忘记您（或其他人）打开它。除了闹钟和计时器外，您根本不会收到其他通知。如果您想关闭请勿打扰(Disturb)，只需说“ Alexa，关闭请勿打扰(Disturb)”。
紫光还有一个含义，但它仅适用于第一次设置Echo时。(Echo)如果此时您看到紫光，则表示WiFi(WiFi)存在某种问题。
一个白色圆圈
调整音量时，白色圆圈会显示当前音量。当你增加音量时，白色圆圈会填满更多，反之亦然。
白灯常亮表示Alexa处于警戒模式(Guard Mode)。在这种模式下， Alexa会聆听您家中的环境声音，并尝试推断是否发生了奇怪或危险的事情。如果Alexa认为发生了什么可疑的事情，她会通知您。要关闭警卫模式(Guard Mode)，请说“ Alexa，我在家。” 当然，假设(Assuming)您有权这样做。
一个环统治他们全部
这可能感觉像是要记住一个很长的颜色代码列表，但是如果您再看一遍，您可能会意识到它实际上并没有那么复杂。一旦您与Alexa和您的Echo 相处(Echo)过一段时间，这个多彩的通信系统就会感觉像是第二天性。
Why Alexa Is Flashing Yellow, Green, and What Does it Mean?
The Amazon Echo smart speakers, powered by Alexa, are some of the best smart speakers money can buy. They sound great, work well and are very reliable. However, from time to time things can go wrong.
Since your Echo speaker doesn’t have a screen, it uses a light ring to provide visual feedback. Even the screen-equipped Echo Show has a small light band that also uses this feedback method.
Light codes are great in principle, but if you don’t know what the lights mean it’s nothing more than something pretty to look at. The good news is that there aren’t too many of these light codes and most of them have fairly benign meanings.
Where Is the Light Located?
The color codes in this article refer specifically to the LED ring found on top of the various models of Amazon Echo speakers. This little ring light can change its color and flashing patterns.
It can even change the colors of discrete sections of the ring. Armed with just this light array, Amazon has managed to pack a surprising amount of information into the system.
You Can Ask Alexa Directly
Amazon knows that few people are actually going to read their Echo speaker manual carefully. Which is why you can simply ask Alexa “What does your light mean?” and she’ll just tell you.
Maybe we should have waited until the end of the article to tell you that, but stick around to the end because Alexa won’t always be in a position to speak so it’s worth knowing these light by sight in advance.
A Slow Yellow Burst a Few Seconds Apart
This slow, pulsing yellow circle might look like some sort of error, but it’s actually nothing serious.
It means there are notifications or messages waiting for your attention. All you have to do is ask Alexa what your notifications or messages are and she’ll tell you.
Hopefully it wasn’t a reminder about your mom’s birthday.
A Blue Ring Peaking on a Cyan Section
With this light code, a blue circle with cyan tips shoots out to meet at the opposite end of the ring. This is possibly the most common light code anyone with an Echo will see.
That’s because it means that Alexa is listening. The light will glimmer in acknowledgement while Alexa thinks about a witty retort.
A Solid Red Ring
While a red ring on an old Xbox 360 meant “Surprise, you have to buy a new Xbox” on an Echo speaker it just means that the microphone has been muted and Alexa isn’t listening. If you’re using an Echo device that has a camera, it also means the camera won’t record you.
If you want Alexa to hear you, you’ll have to press the dedicated mute button on your Echo and the red ring should turn off, indicating that Alexa is now ready to hear your request.
Spinning Blue Ring
If you’re seeing a spinning blue and cyan ring, it means that your Echo device is starting up. If everything is OK, the ring will flash cyan-blue and then turn off. If this is the first time the Echo has been switched on, or it has been reset, then the light will turn orange.
A Spinning Orange Section on Black
If you see this, it means your Echo is in its initial setup mode. It will first try to connect to the internet and then proceed with all the housekeeping it needs, which might include downloading updates.
It will need your help using the Alexa app to connect. If you need help setting it up, check out Getting Started with Your New Amazon Echo for a hands-on walkthrough.
Pulsing Green
If you see a pulsing green light, congratulations! It means that there’s an incoming call and someone wants to talk to you. Once you answer the call, the ring will change to a spinning green light. So go ahead and say “Alexa answer call” to find out who wants to have a chat with you.
A Purple Flash
For an Amazon Echo that’s set up, a brief flash of purple after you’ve asked Alexa anything means that you have Do Not Disturb Mode switched on. This is a handy reminder since it’s easy to forget that you (or someone else) turned it on. You won’t receive other notification at all, with the exception of alarms and timers. If you want to turn Do Not Disturb off, simply say “Alexa, turn off Do Not Disturb”.
A purple light has one more meaning, but it only applies when an Echo is first set up. If you see a purple light at that time, it means there’s some sort of issue with the WiFi.
A White Circle
A white circle shows you the current volume level when you adjust the volume. As you increase volume the white circle will full up more and vice versa.
A solid white light means that Alexa is in Guard Mode. In this mode Alexa listens to the ambient sounds in your home and tries to deduce if something weird or dangerous is going on. If Alexa thinks something fishy is happening, she’ll let you know. To turn Guard Mode off, say “Alexa, I’m home.” Assuming you’re authorized to do it, of course.
One Ring to Rule Them All
This probably felt like a very long list of color codes to remember, but if you look again you’ll probably realize that it’s actually not that complicated. Once you’ve spent some time with Alexa and your Echo, this colorful communication system will feel like second nature.
