12x BR DIODES

Dave,

Yes, this is how I had it hooked up.
Sorry if I was not clear about that in my post.

My point was that the value of knowing the current on the supply side is very limited. It can probably be eliminated. Everything else was cool.

Peace,
dave
 





FrancoRob, did you receive my PM? I sent one on to you earlier about my 12X.
 
Thank you for posting that plot. It's nice to see the supply amps down. It helped me get a better feel for how much power a flexdrive is drawing to boost the current. While it has little bearing on the final output, it does help me better understand how long a battery might last powering a flexdrive and a 12x diode. i.e. at around 400ma it would appear a 900mah battery would last a little over an hour. (but not much)

As the battery drains, the flexdrive uses more current.

Lower charged batteries = higher current need.

Peace,

Nice work -- the experimenters here love the data. I read your data and mine and I see a little different slope on the graph but we AGREE at 490 mA !!! Also, Your Vld is higher than mine and I thought mine was high !!! My Vld at 490 mA was 5.7 V.

The driver input current gives you an idea of battery life etc.

Yes, I received your PM, sorry for the delay in answering, but I had some problems in these days.

It would be nice you can complete your info with the driver (it's a V4 or a V5 Flex?) and the lens you are using on your 12x, but more important is the P.O.: 305mA means that your P.O. could probably lie between 440 and 460mW, but it is a supposition, as each diode shows, let me say, a personal output behaviour....:thinking:
So I think it would be really useful if you have a friend equipped with a LPM to check the P.O. of your Ehgemus Mini RPL. With these data I'll be glad to add you in the 12x Owners datasheet. :yh:

great datasheet! I'm definitely going to get add a 12X BluRay to my future laser collection list now :san:
 
Rob --

Graphing FF-Racer's points with mine will show a different power slope on the graph.
Might be interesting in light of the different Vld's reported.

12x Drive number 2 arrived tonight. The diode in this drive is something else...

Vf on this diode is running at 5.88V, where my first diode ran at 5.48V. I put this together in a second host identical to the first from Jayrob.

Output peak: 626mW @ 400mA!

12x 405nm #2 results:

Diode Source: BDR-205BK
Driver: V5 Flex
Current: 400mA
Host: Jayrob's Slim 18650
Lens: 405-G-1
Total burn time as of 02/08/10: ~2 minutes
Output Peak: 626mW
Output Avg: 620mW+
Power source: AW 2600mAH protected 18650

The only differences between my two builds is the 0.4V forward voltage difference, and 'BK' vs 'BKS' model numbers.

Figured I'd take a second snapshot:

speechless. just speechless. :drool:
 
Looks like the V5 FlexDrive can handle the 400mA's...

There are definitely differences in diode efficiency and forward voltage as well. And drlava did say his FlexDrive could deliver 6 volts of forward votage at 300mA's... (he was probably being conservative with that statement - guessing)

Looks like it can deliver 400mA's at 5.88 forward voltage!

Total amperage on the 626mW blu-ray, on a fresh batt: ~640mA. :whistle:

640mA is not what your diode is getting. Supply side pulls more current than the diode side does with a boost driver.

Peace,
dave
