Help is Needed

[witch_king]

I have a diode from a burner that was disassembled, and I don't have any idea about what voltage is needed, what power will make it work good, etc.
It will be great if you create an appropriate electrical circuit, or matching specifications, so that the diode will not be burnt.

Here's the details of the burner:
40x12x40 LG

>ABS+PBT<
IPT-1-1
JE4

2 3974 W2
1162A012BF

ALS

And another question- will such diode be able to light matches or terminate balloons?

Thank you, awaiting your response.

Have you done any research for yourself? Search for Lava driver V4 or for Rockstr drivers. Both of these drivers will work fine for what you want. They will adjust the voltage automaticly for you. To be honest, it's the current that you need to be woried about. What ever you do, don't hook it up strait to a battery.

You do have a Aiziz module to put the diode into right? Heat sink? anything?

I want to connect it to an appropriate resistor, that's why I asked for the voltage and power...

I have alreay tried to find myself the info I needed, but I haven't found it yet, thats why I asked for your help

you need a lot of things buddy! here is a list: aixiz or sure module with lens, a diode driver (rkcstr, or flex drive) good batteries, safety goggles! now search for the items i described and you will learn along the way of how it all comes together.

This guy is right.

Laser diodes are current driven. Don't just add a resistor. If you do, there is a high chance that you will BLOW THE DIODE. Buy a flex drive. Run it with a single 3.0V to 4.2V battery. (Lithium)

I don't know if this link still works but give one of these tutorials a try. If you do manage to view this link, I would print it to paper.

Couldn't you just tell it doesn't work like regular LED and that voltage regulation is needed for 200-250mA and 2.5-3v?!~

Thanks anyway...

You need to do some reading on the Forum...
All the correct information you want is posted...

We are so sorry that the correct information that has already been
generously supplied to you by the members above... does not agree
with your Noob ideas of only using a resistor to power your Laser Diode...

Use the [Search] button and do some reading and you too will see
how wrong you are..

Of course using just a battery and resistor works; and I'd like to get an explanation of how you can "blow your diode" that way (except by a gross miscalculation - something that can happen just as easily with a driver).

The point is: the voltage of a battery is variable (depending on charge and drain), and the voltage drop over the diode is variable (depending on current); both of these can also vary with other factors like temperature.

Using a driver lets you ignore all of those complications. Within limits, the diode will always get the specified amount of current.

If you determine the voltage drop over your diode at your target current, and the voltage of the battery, then you can calculate the required resistance using Ohms law and run your diode with nothing else - just like any LED or other diode.

However, as the battery drains, its internal resistance will climb, the voltage will drop and the current to the diode will as well (partially compensated by the fact that the voltage drop over the LD will drop as well), so as with a simple flashlight, it will get dimmer and dimmer over time.

Also, as the diode heats up, the voltage drop over it will decrease as well; that will increase the current, causing further heatup... this may lead to a runaway effect, but only if you've cut everything close (current close to the max for the LD, resistance very low).

If you use a lab power supply (stabilized output voltage), you've cut the main variable out of the picture...

Dr-ebert, thanks for the expelantion... Now I can understand the physics behind the "nonsense" people have said, and to build it intelligently.

 

[chipdouglas]

:wtf: so let me get this clear. You would rather keep checking this thread for days and days instead of taking our advice from day 1, and do your own search. And we are the ones that are "non sense". You are so worried about inteligence that you choose to ignore 4 members giving great advice. You just want somebody to agree with you so you have accountability for when your diode dies. :twak:

edit* if you want inteligent answers, then ask inteligent questions. You tell us only that you have an LG burner and want to know if it will light matches and pop baloons. sorry if we tried to let you know that you have a little more to worry about than a resistor.

btw, good luck

Hey, all I have tried to do was to use my knowledge in electronics(and I do have some) and to match what I have already known about diodes... I have seen in the forum a some electrical circuits, and most of them were compicated than what I wanted to use, some I still see as coplicated thand what is needed for me... After what Dr-ebert have said I have become smarter... Now I anderstand why I shall do what seemed to me at the begining as "nonsense", because now I can understand why to do it that way... That's all...
As smart man have said: "when you'll give the kids knowledge and not answers, we will be able to give them the spring."

I am really sorry about the fact that I was referred to your site just because I was told that you will be able to give me the information I was needed, whilst you gave me just the info I did'nt ask for...
I tried to find it myself, and I couldn't- that's why I asked for your help!
But I steel thank you!

I shall also mention, that I use the word "intelligently" when what I hear suits the theory and what I was teached, and simultaneously can be understanded logicaly.
Reasoned answer is better than something which is "out of the blue"- without any explanation...
If you will give me a rigorous reasons, I will see your answer also as "inteligent".

I also want to say, that my goal isn't to make you angry, or to insult any of you- I just want to clarify myself here...

Dr.ebert feels comfortable using resistors. Most members here don't. like ebert said in his post there are so many variables. and the driver takes those away and prolongs the life of the LD. You have electronics experience, have you seen the ddL tutorial? I have zero electronics experience, and with help here and google I made one with all the parts from radio shack.
it is a bit rude for you to bite the hands that feed you.
