New 6X Continuous-Duty BR Build

P.S. I make the thermal epoxy with #800 aluminum oxide powder.

Where you got Al oxyde ? ..... the only thing i can find around here is Al powder, that make the resin a bit conductive, damn .....
 





well Larry time to go into the driver/lens bussiness oh!... yea.:)
<me holding a wad of ones>

I have many pounds of it.

It is used to polish stone and other materials.

You should be able to find it in Europe.

Let me know if you can't find it.

Thanks for the info Larry. I'm gonna try a couple of these drivers (still waiting for them to get back to me on combined shipping). I was thinking about soldering a really small POT to the driver, as I don't have any surface mount resistors laying around.

Rayfoss will set the driver close to the current you specify.

Well rayfoss has yet to answer any of my emails, so I'll just order one (since there's no incentive to buy two right away) and see how it goes.

Hell, i searched around in chemical, paintings and arts stores (found Al powder there), and never thought about this application ..... thanks, next week i'm in city and i will check if there is the possibility to find it for this use, and let you know if not (here in Italy, sometimes, is difficult to get the things that you want, just cause they sell only in "industrial quantity", like, 50/100Kg or 100/209 liters packages).
 
HIMNL9;

There is plenty of marble polished in Italy ...

Any shop that does it should be able to sell you some.

LOL ..... Yes, i was searching it only in chemical sellers and paint stores, so no results, or just industrial packages .....

Now that you pointed me in stone polishing process (and i never thoughd about that, before, so thanks again) i found it ..... and guess where ? (bet you cannot guess so easy :p) ..... Funeral agency, LOL ! (and they are 200 meters from home, where i gone til city 50 Km far for found nothing, before :p)

They made themselves engraving and polishing of grave plates, so when you said me about stone polishing, they came in mind first, and yes, when i phoned them, they said that they have it and can sell me (just have to go take it) :)

Is curious how, sometimes, we are so used to think for "classes" (mean, Al oxyde = chemical = chemical stores), that we don't think to more easy alternatives ..... :beer:
 
HIMNL9;

I'm glad you found the aluminum oxide.

The UV laser was a hit in Vegas ...,
where I demoed it to several trade people for stain removal.

Nice, but way to big imho. Probably wont fit in a pocket lol

Can it run a 8x non-stop?
 
It probably could. I would definitley think so with a copper heatsink. The heatsink has a great amount of volume and exposed surface area. Every time I look at this build I like it more.

(n00b questions alert!) So you just put thermal epoxy straight onto the diode and then pressed it into your heatsink? How do you attach your lenses to the diode? Or was the diode in an aixiz module? Can you provide a link for the host larry? Thanks.

For maximum heat dissipation, I guess thermal epoxy (like arctic silver) is probably applied to both the diode/module and the module/heatsink.

Also, I doubt it can run an 8x continuously. I mean, it probably cant dissipate the heat from the host to the air as quick as the diode heats the host. Can it ?

Anyone know much heat PHR / 6x / 8x generate (using standard safe amps)

Wait so Larry what do you think of the Beast. Or are you going to be modding and selling some of your own hosts :)
 
ZRTMWA;

The Aixiz module was a press fit in the heatsink.
The thermal epoxy was used to decrease the thermal resistance between the module and the heat sink.

The host is here:
Hard Anodized Host

I think it would be fine for the 8X, since I have operated 3W UV LED's in it for long operating cycles (8X are <2 watts).

It is only 5" long for the #18650 battery. That's as small as you can get and dissipate 2-3 watts of heat.

P.S. Mandalorian- I haven't seen the final dimensions for the beast.
It needs to have the same mass and surface area for heat dissapation.
