Jetbeam TCE 1 led pcb size ?

Can anyone enlighten me on the size of the led star?

I dont know
what are you wanting to accomplish?

The light is XP-L, so I would not need to change the mcpcb to install a Nichia

do know that a 16mm mcpcb is too large for an RRT-01, by about 2mm
dont know if the TCE-1 uses same board size.. the RRT-01 is XM-L

friends here found some handy 12mm mcpcb, far away from you.. but Im willing to send you one or two, if it helps.. PM me

but
Why:-)

Jon the tint is slightly towards the green side, so i thought i might try a white flat on a 16mm pcb from Hank at intl outdoor.

Thanks for your kind and generous offer of the 12mm but i wont need them as i can try to reflow the white onto the original pcb if i have to.

I have plenty of xpl hi,s but would like to make this little guy crank out the most candelas for a bit of fun, plus i do not have any lights with these leds. I will order the leds by them selves and some on 16mm any way. Thanks.

sounds good
you may find these videos inspiring, I find the tight beam impressive:

That RRT 01 is very impressive with the W1 – very nice defined hotspot- thanks.

I am ressurecting this so all relevant information is here.

I have, with difficulty, opened the bezel of my TCE-1, which was stuck, with loads of red loctite.

It seems the MCPCB is screwed to the body from behind! I cannot see how to remove the driver to access the screws. Does anyone know?

From your pictures it looks like there are holes in the driver to allow you to insert a screwdriver and access the screws. Maybe try that. If it works, it might not be necessary to remove the driver to remove the star.

To remove the driver, my guess is desolder the driver wires from the star, then insert a wooden toothpick or awl and press the driver out the back from the front.

The holes are not aligned with the screws. They are 90 degrees angle from the scews.

I did desolder the wires and tried to push the driver out but it did not budge. I think the button would need to come out but I do not know how. The driver may be glued?

Any ideas welcome. Knowledge, even more.

Maybe reach into the holes with a pliers and try to pull the driver out?

I tried gently but the driver has to be held there by something, otherwize it would come out all the time. I have to find that something before I apply a lot of force and break anything.

or the driver may be screwed in

and can be unscrewed now that the wires are free

The driver seems connected to the button, which protrudes from the body and cannot be turned… I am reluctant to apply a lot of force without knowing what is going on.

The holes on the driver serve to hold a plastic cover so they may very well not be related to anything else.

The MCPCB looks like it is not held by those ‘screws’.
Is the white stuff firm or like paste, could be thermal glue. May need prized off.
Driver looks press fitted & probably glued, see those tabs on either side with channels for them cut into the threading? Pressed into place.
Don’t mess with the driver if you don’t have to.
I could be wrong though.. Innocent

CRX, I think the screw heads are on the inside and the screws go through the MCPCB and thread on the body. The white paste is normal thermal paste which is easily removed by a q tip, so not adhesive.

I do not see anything holding the driver in place, so I am also afraid it must be glued. Press fitted is not an option as there are threads behind it. It feels like this light, despite being expensive and “luxurious” is not really serviceable.

I fear I will have to keep it with the LED it comes with, unless someone knows a better option.

Right so the MCPCB goes under the shelf not sitting on top as it looks?

Yes, I am sorry this is not apparent from the angle of the photo, the MCPCB is under the shelf.

All becomes clear Big Smile

Yeah you would need to pop the driver, could be dodgy but it does have those useful holes there.

How would I pop the driver without causing damage? I tried pulling and twisting through the holes with all the force I am comfortable using. There is also the matter of the protruding button on the top of the light, that is connected with the driver. Maybe it is just touching, maybe it is more rigidly connected.

I have never opened a light with this configuration before, with the MCPCB behind the shelf and no apparent ring or screw holding the driver in place. If the driver is glued, I am probably, as well, stuck Silly

It can be tricky and there’s every possibility of breaking it, it mostly depends on the glue type they used and how much.

The driver & switch unit will consist of the contact board you can see and a perpendicular attached switch PCB.
It should pull straight out, no twisting etc.
The metal switch will have a rubber seal of some sort and pretty much stays in place when you pull out the driver unit.

See those two brown rectangles in the driver board, those will be support for the switch circuit board.

In situations like this I usually use some heat to soften the glue and gently pry it where I think there is no components, probably the outside edge of the hole.
You could try poking from the LED side too but need to be careful of knocking off SMDs etc.

Thank you very much CRX. All very logical and useful information.

Judging by the copious amounts of red loctite on the bezel, which was an incredible PITA to remove, I guess there is going to be a lot of epoxy holding the driver in there. It is crazy that they did not just use a normal retaining ring to hold it in place.

The light has been put in hot water many times, in a plastic bag, to soften the loctite on the bezel, but it did nothing…

I will ask Jetbeam if the driver is glued and if it is, I will probably leave it as it is.
