LED带灯的嗡嗡声声音
TVRGEEK|Posted inEnergy Efficiency and Durabilityon
因此，尝试提高效率。将8个4英尺的LED带灯放在我的商店里，并获得4个便宜的可怕的恐怖悬挂式商店灯。很多光。非常有效，但它们嗡嗡作响。HF灯还用RF污染消灭了我的FM收音机。其余的只是烦人的。
谁制作不错的灯光灯和悬挂灯，这些灯和不沿着胳膊和腿沿着腿部沿着嗡嗡作响？我几乎认为我应该只用一堆旧学校的基本固定装置并拧入灯泡，但这需要很多。
我是一个老人，需要很多光。

Stick to brand names. Can't go wrong with Phillips Sylvania, Liteline. Simplest is to go for T8 or T4 bases.
I've had pretty mixed luck with any of the tube lights from local box stores. Some work well, some have similar issues you mention.
I have a garage, shop, and two basement mechanical rooms full of Metalux LED strips. Couldn't be happier.
我对Costco拥有的Feit Electric Light好运，但是较旧的电灯 - 不是带有运动传感器的新电灯（我没有任何新的）。我有大约25-30旧的年龄段，其中有些超过4年，没有问题。
除了我从Costco拥有的产品外，我还将第二届Akos的建议坚持传统品牌名称。我在工作中的商业项目中使用了许多Lithonia灯具，但问题为零。我也使用了视灯，尽管我不确定它们会做您想要的类似的东西。
顺便说一句，如果HF不会收回那些擦掉收音机的灯，请告诉他们您想将它们带回去，因为它们会引起所有RF干扰。如果他们给您麻烦，请告诉他们您正在考虑将其报告给FCC。FCC实际上不会做任何事情 - 他们的人手不足 - 但这可能会让HF退还您的灯光灯具。

Thanks. I see Home Despot carries ( gets) the Metalux ( Cooper) for not a terrible price. They have the 8 footers as well. I'll look for Lithonia as well.
FCC是没有用的。在MD电力变压器that wiped out radio for two blocks. Neither the FCC, nor the power company cared. Of course, it eventually blew up. Now when IBM complained our unit was a couple dB over spec, they came down on us like a train.
只是将嘈杂的垃圾放在爬行空间，车库和地方，这没关系。当您在工作台上切几个燕尾服或用飞机形成一些库存时，嗡嗡声会破坏禅宗。我喜欢在后台上有“古典电台”。
好吧，去了从高清购买的库珀。$ 45。比HF的$ 12好吗？不，甚至更糟。取回。
这些灯光是否有机会变暗？我怀疑不是因为它是一个研讨会，但LED对错误/不兼容的调光器敏感。
Maybe see if you can get some of the Feit Electric fixtures. Mine are completely silent.

控制开关吗?旧灯的开关es (including dimmers) are not compatible with the lower amperages of LED lights. Aside from looking at brands, look at the light switch.
Old SWITCHES are fine regardless of load. Old switches were just mechanical contacts.
Dimmers have issues because they work by chopping up the sinewave, so you need one that can keep that consistent even with the nonlinear load presented by LED light fixtures. It's not really the amperage that is the issue, it's the way they draw power over the sinewave, similar to, but not exactly the same as, power factor.

Switch. No dimmers.
Neither the HF nor the Cooper buzz audibly; they wipe out the radio. My overheads are what buzz so audibly, but they don't seem to effect the radio.
因此，请使用Internet Radio。FM无论如何都是恐龙...
I would try running the lights on a different circuit just as a check. LED lights are usually pretty trouble free, if you're getting buzzing with lights from two different manufacturers I would rule out an issue with the circuit before trying a third brand.
不，不仅不是，现在。我不做流媒体。我喜欢我的FM“古典电台”和NPR。
我用电话打电话。我在电视上看电视，并在计算机上计算。
并且，RF干扰直接违反了FCC规则。为什么由于公司不尊重法律，为什么会给我带来不便？
查看是否可以将RFI源定位在固定装置上。如果是来自固定装置本身，那么很难做任何事情。如果RFI被电源线辐射，则可以通过将电源线包裹在铁氧体环或夹具芯上来减少干扰。一个例子就是其中之一：https://www.mouser.com/new/fair-rite/fair-rite-cable-snap-ist/
You would probably want the type 31 material for your application, and you need a big enough core to be able to loop the power cord through a few times. you want the core up close to the fixture too.
Yes, you're not supposed to have to deal with things like this, but RFI has become a big problem. The FCC doesn't usually do much, if anything, and most people don't notice so it becomes a "not a problem problem" for a lot of companies. Things have gotten so bad that some cheap computer power supplies are missing the RFI suppression components on the internal PC boards -- you can open them up, see the spots on the board for the suppression parts, and see jumpers installed instead.

我在山阴影中，所以我必须在互联网上听NPR和古典电台。奇迹般有效。并走出来，但是互联网上有很多电台可以听。您应该尝试一些时间。他们是新鲜的事物并不糟糕，是的。
我尝试了房屋媒体服务器上的一些流媒体内容。屁股不可靠，疼痛。
使用收音机，您将其打开。没有计算机，没有50次点击，没有密码。
我在服务器上加载了500张左右的CD。以为我只会有各个站点的捷径。不起作用。
Computers are a tool. If they don't do what you want, they are not a good tool. BTW, I am a retired computer scientist. I know how they COULD work. Bad interfaces.
Tried the ferrite clamp on.
这里有两个不同的问题。
Buzzing is typically from low quality magnetics in the the supply section. Very annoying to fix, I've dealt with issue with early generation LED bulbs used as a reading light. Worst part is the cost difference between the right part and the one they used was pennies but it took a couple of hours to disassemble, replace and re-assemble everything.
Some level of radio interference is generated by any switching power supply. Almost all LEDs have switching supplies. Even the ones that are certified will have non-zero EMI. Typically managing EMI costs you either extra in filtering components or losses in efficiency, most designs only aim to be marginally bellow the FCC limits. Now you take a dozen or two of these switching supplies put them in a metal building, chances are it will effect radio reception. There is really no way around this. About the only thing you can do is go for LEDs with external drivers that you can mount in a metal enclosure and all wiring inside metal conduit. Not cheap or simple.
The reason your overhead lights don't effect the radio is they have magnetic ballasts. These don't have any switching components so they don't generate any EMI.
