How to connect Kessil A360w LED Chip

Spliffen · 09/12/2019, 02:24 PM

Hi ,
I have a dead light , that i have stripped down.
I do think that the LED chip is ok , but dont know how to test it.
There is 10 cables to the chip , four black two bown four black.
Dont know what V or A to what cables =)
And of course Kessil said to me that it is confidential , so no help from them....
So I´ll try to reach out to the community for some help instead.

Got a multimeter?
Got a constant current benchtop power supply?

Can you take some detailed pictures?

Yes I have a multimeter , and also a constant current power supply.

An adjustable CC supply?
Pictures?
Tried probing the pins with the diode test function of the meter? Got a table of the results?
Named the wires for identification?
,etc...

I got two of those and the chips in them should be good.
Following along...

I have not tried to probe the cales for results yet.
A bit out of my area , i guess=) , but i will try it later and see if i can understand something from it.

Can you give us photos of where the wires connect and more?
Take like 20 pictures of various parts..
We can trace down what goes to what and potentially help..

The more data you can give us the better your chances..

And of course did you already check to make sure the adapter (power supply) is outputting what it should be?
I think they are 19VDC supplies.. 4.7A

More photos in the link above now.
The power supply was the first thing i suspected , because i measured zero V from it.
But the problem was it was in protection mode due to short circuit.
So the main problem is a short circuit in the main board , and since i`m no technician , i gave up.
Now i just try to save the LED chip for some project-

Did you already post this on the other reef 2 reef forum
D2 certainly looks burnt

Spliffen · 09/13/2019, 03:16 PM

Nope , first post about it.
Sounds familiar with another post I've read some time ago.
But like I've said before , i have given up the hope for the other stuff , just into the chip right now 😅
