LG GSA-4163B help

[3zuli]

I just got this drive. I've already done some searching and found out it's 16x drive and the red diode is the one with massive heatsink. now the questions: what mA should I drive it at? what mW will it give? and the pinout is the same as for other red's?
also, the diode is placed in a small heatsink like the SmOC diodes from BDR sleds. how can I extract it safely? any tips?
thx for help

:bumpit: anyone?

Pics might help. And so far (other than flat reds and 4-pinned IR/Red diodes) the pinout is the same for all red and IR diodes.

@ JellyCrab -- Please stop posting about things that you do not understand.

@ 3Zuli -- Unless someone has worked with this specific diode/sled you must work up this information. If you are going to work with an "unknown", be ready to do the science that you are asking for.

The forum would appreciate your posting what you find.

If you do not yet understand how to test for the things you are asking, read some more in the "experiments" and the "review" boards.

Peace,
dave

I know sth about testing, but I don't have an LPM so I can't make the current vs. output graph
I've found that someone was driving this @ 200mA and it can be pushed up to 250mA, so I will try...
I'll take some pics

SWEET!

Even if one person has postd info about it, you will still need to do some "experimentation." After we get "several" people getting the same results, only then can we begin to "know" this info.

Thanks for entering the "research" side.

it has 2 diodes, red is 5.6mm 3 pin short closed can and the IR is 9mm 3pin, seems to be short open can
btw it's a 16x drive. what's the usual mW of 16x diodes?
here are the pics:

the sled optics

the IR LD assembly; any info on this?

the red LD
I forgot to take pics of the sled before disassembling but it looked very similar to LPC815 sled
also on the back side is written:

4L12
0067
1692

edit: this sled looks ideal as RGV combining optics

so, testing is over :cryyy: I extracted the diode from it's heatsink (I broke the window ), inserted it into Aixiz and set the current to 220mA. it lasted about 30 minutes then and then LED'd :cryyy: probably would last longer if I didn't broke the window:banghead:
but it was burning like a lighter
