"Sky Ray 9xT6" issue from CNQG

The Fujik is just another brand.

Theres two different types

Thermal GREASE, which is comparable to the arctic silvers of the CPU world.

And thermal GLUE which is what i linked to you before.

The glue type products will adhere the LED stars where the grease will not.

Arctic Alumina is the comparable one to the Fujik that i posted before.

Its just a different brand. If you want to use the same stuff that’s on the flashlight now your looking for the fujik glue. Its way easier to work with.

Just don’t use glue or alumina on your CPUs!

Good point… I haven’t been to Harbor Freight in a few years, so it might be a good excuse to go. Thanks!

That’s nice and cheap… and potentially useful for other stuff. So there shouldn’t be a problem with a direct contact on the LED? Thanks for the link!

Ahhhhh… Thank you for the clarification! That makes a lot more sense now. Gonna definitely order some Fujik.

I can’t see where the above mentioned black wire goes. Please make some pictures of the LED wiring from different angle.

Both of those black wires are soldered onto that LED as indicated by the picture below. The orange dot represents where they are soldered together onto the LED.

It might still be a little difficult to see how they are soldered together there… but there appears to be good contact. Also, since the central 3 LEDs are still functional, there should be good contact there. The negative wire comes off the driver and is soldered onto LED “1”. Another black wire then connects “1” and LED “2”. This happens at the orange dot. Next is 3, then 4, etc.

Looking at that wiring, I'm going to say it is the problem. The wires are supposed to wire them in series, and I don't think that is what you did. (May be wrong)

I modified the picture. It may need to be refreshed if it doesn’t show the alterations.

The wires marked by the blue arrows were the ones that were clipped and that I initially replaced. It was pretty obvious where they were connected, so I just replaced them accordingly. The white arrow marks the re-soldered black wire that firelight2 suggested. I don’t think I wired it incorrectly, but it’s been a while since I’ve taken electricity and magnetism in Physics so it all seems pretty foreign now.

Ok, are your LEDs wired like this?

P.S. Have I won the award for crappiest paint drawing yet? :P

There should be no branches (two wires connected to the same side of an LED). You have at least one branch in the red wires. You need to wire them like Scaru has drawn. There should be one wire going from the + of one LED to the - of the next LED.
Edit: Make sure the red wire coming from the driver goes to the first LED + and the black driver wire goes to the last LED -.

No his wiring is right, if I remember correctly there are 3groups of 3 parallel.
And this is what I can see.
This would also make clear why just the 3 in the middle worked.

What is status quo? Does it light up?

The wiring is in the same configuration that I received it in. This is a very crappy picture of the basic wiring:

Haha, I think my pic might be worse than yours now scaru… although yours does have elliptical LED’s…

Ok, if it is supposed to be 3S3P does your circuit diagram follow this? (Your drawing confuses me :P )

What is the actual problem? Which LEDs light up and which not?

The wiring seems visually correct for me.

Haha… yeah my diagram confuses me too even. But yes, it appears that it follows your wiring configuration scaru.

The problem is that currently only the central 3 LED’s are lighting up now. But prior to that, 7 of them were lighting up.

I think scaru is correct

the led that is furthest to the right has a wire coming off positive and going to a positive

even if they’re supposed to be 3s3p, they wiring is incorrect

instead of drawing on the picture, I suggest recreating the way it is wired in a diagram that is easier to read (like scaru’s)

Wiring is right! I see 3s3pi have marked groups with colors

The furthes right goes direct to driver just with a short visit at the other led

bingo.

Yeah, the wiring is screwed up. Truthfully I am having a hard time figuring out what you did but it isn't right. :P I'm gonna try drawing up how it should be wired on one of your pictures for ya.

Ok, first of all here the correct wiring is. Each color is a 3S group.

And here the fix is to make it correct.

Now I am confused isn’t this the same way like it is?

Thank you for the replies…
aoyue, it actually wraps around (orange line)… see diagram below for what I mean.

Scaru, it is actually wired like that right now. It just doesn’t seem that way in that particular pic, but the one I posted with the orange dot should.

Edit: Yes Werner, I believe so.

I made a sloppy diagram on sketchbook, but I tried to maintain the relative orientation of the individual LED’s:


This should more or less be similarily oriented:
