The method that I told you what I have done in Samsung and Sharp TVs that bring that type of LED with acrylic screen as a diffuser, as you will see they do not have enough space to put large round LEDs, since it is complicated to remove and put in place of the small leds,
Good morning Javier, I ask you another question to be able to change them, I took off the strip from the heat sink, do you know what kind of glue it had, carries it or can it be put so that it dissipates the heat? As for the LEDs I ended up buying one of 3 V and I soldered them and in the test they failed a couple more luckily buy others now I do not want to continue testing for fear that the temperature I burned someone else.
I really have no idea exactly what that kind of glue is, you could try any one that adheres firmly to the heatsink,
I imagine that some sticky tape would be good but I really have no idea of any that is indicated, I never take off the complete LED rod, for the same reason that it cannot be re-adhered as it originally came. And it is for that reason that I told you about the adaptation of normal LEDs and to accommodate them in another place by extending cables.
Good day, I commented that looking for I found different adhesive products that also dissipate the heat produced but I can't know what temperature these 72 LEDs can generate for me and I need it to be able to choose the adhesive. As soon as the houses of sale of led only know of what voltage and dimensions.
