In our last posts, have we already shown you how to build LEDs High Power LEDs or LED-Strip lights self-made, and in the new FAQ section explains what led at all, but you actually have any idea how the LEDs themselves are made?
How Are Leds Manufactured?
So roughly, it was already aware. But I was surprised how it exactly works. Above all it looks alike such as in factories, which are known from the production of processors. I myself am a big fan of these videos that explain how something is made anyway. So, I was even begun as Christian sent me a link to this video from OSRAM.
The video, which actually comes from the OSRAM subsidiary of OSRAM opto semiconductors is inconspicuous named “Light crystals”. And the names we’re also directly in the matter. Light emitting diodes are diode and use semiconductors. Meet the negatively charged electrons on the positively charged “holes” (who remembers the physics high school?) visible light is emitted.
The Biggest Surprise for Me Is the Choice of Location
The video is very interesting and full of surprises. For example, I did not know that the protective layer on the may be not smooth finished LED, because she otherwise would reflect back most of the light LED to the. Thus, roughened by the protective layer through a chemical process and the light thus scattered something, which prevents the reflection. This and much more you learn this really great made video by OSRAM.
Particularly impressed has honestly me also, that all of this takes place in Germany, in Regensburg, Germany. Only the final Assembly takes place in the far East, in Malaysia. So want you no longer on the torture span, here is the video:
Well, what do you say? Are you impressed by the production of LEDs? I was there in any case. Or was already clear to you how it all works?
You Are Interested in the Technology Behind Leds?
If you count to our more technically interessierteren visitors, I would like to create the following three themes at the heart of friends that also might be interested:
- The great infographic to LED technology
The infographic is indeed from the year 2012, but still a good overview of the State of the art. Maybe it’s time to publish a version of up dgedatete 2014 sometime soon?
- Scammed in China-LEDs?
It seems are match the information in the description often not with the actual values. Christian has investigated here once more.
- What are the LED trends in 2014?
The LED market is a huge growth market.In this post we have you suggested once, what might happen in the year 2014 and what more likely will not happen.
