This thread is going to be a catch all for some small insights of things I am working on. Given the sensitive nature I will not be revealing all the details of how or even what is being done. But I thought some may be interested to have a little peak at what I am working on in general.
I am attacking this problem of improving the state of the art from many many angles. Since I cannot alter or create epi layers I am focusing on thermal and optical modifications as well as developing ways to mix and match LED's constituent parts from end products. This means finding ways to remove or alter encapsulants. Remove and alter phosphor layers. Remove LED dice. As you can imagine trying to tear apart an end product can be tricky to do without damaging the underlying structures such that they can be used again. So I spend copious amounts of time developing theories and then testing those theories. I am a mass murderer of LEDs. Hundreds of LEDs have been slaughtered over the last few months. It is expensive but the only way to move forward.
I hope you find this thread interesting.
This is a Nichia 219C. One of the things I work at is getting the various layers to separate where I want them too. In this case I wanted to split the encapsulant off the phosphor layer. This LED is particularly difficult to do this with. This picture shows a near perfect separation.
