DIY LED color mod

i was browsing some chinese website and came across this DIY kit for changing LED tint color (that's what it does, if i understand it correctly).  i thought this is interesting and i just wanna share this with u guys.  is it something new? or do u guys know about it already?

the kit comes with 2 bottles of glue, 2 bottles of phosphor powder, and a battery holder for testing the LED.

according to the site, the steps are as follow:

1. mix glue A and B in 2:1 ratio

2. add phosphor powder A and B to the glue mixture, different amount gives different tint

3. put the glue and phosphor mixture on the LED doom and then test it.

If this kit actually works, we can change our LEDs to whatever tint we want. no need to wait for the manufacturer to come up with warm tint.

after a closer look, this product came out in 2008. but i have never heard ppl talk about it.  has anyone tried?

Interesting idea. Usually the phosphor is on the die, not the dome. And it seems like you'd need some skill and a steady hand to get an even coat of stuff on a dome. I'll definitely let someone else go first.

You would need to put the phosphor in the place where the phosphor already is in a normal LED (it's the yellow you see when you look at the die), so this really isn't for general use.

 

The LED supplied with the kit presumably is phosphor-less and only covered by a thin layer or resin instead of the normal dome.

it's probably a bad idea to dedomed a good LED to try this.
