1W 525nm Diodes!

Ah the joys of not posting every day.
Whelp *cracks knuckles* two-fifty to go.

Well I suppose it couldn't hurt.

The initial tests on these diodes were about 1.2W @ 1A. The beam is size is sort of between a 445nm diode and a 638nm diode.

They LED somewhere around 1.3A. A very expensive LED.

There isn't many of the diodes to go around just yet, so that's why it's just the vets at the moment :can:

so your saying they are already in the hobby hands O_O

Not allowed to say. The vet section is confidential.

Haha, sorry guys. I had to. Did neither of you read the edit comment?

No one has these diodes yet, I was just pulling your leg

 

[ZRaffleticket]

Especially since they were just developed?

 

[Cel]

Hm, they are going to be expensive, so I expect frequent use of them after at least 2 years from now.

(The future versions, upgraded ones)
I am worried about the beam specs - multimode probably, now how long the lines will be?

And what about efficiency? Voltage? Current?

Dimensions?

Will that remain the same?

Man that got my hopes up :banghead:

Multimode probable, no way can they multiply output by 10 by increasing efficiency a few %. If they want it for a TV the lines would need to be small to be easy to work with.

Only the developers know, except the efficiency... In the article they said 1.5 times the efficiency vs the normal diodes, so 9% * 1.5 = 13.5% efficiency.

We'll need somewhere around 7-12Vin between .7A to 1.3A.

Case needs to be protecting the die, or else it will oxidize so it'll need to be closed-case, standard 3.8/5.6/9mm diode size probably.

 

[Cel]

But that efficiency doesn't have to be exactly x1.5... But over 10% it is incredible (for 500-550nm)!

 

[ZRaffleticket]

It's still a factor close enough to 1.5x, it's more or less for each specific diode as well, and what I did was a rough calculation, the upgrades will certainly optimize that.

 

[Cel]

That is still a good increase. :beer:

 

[Mrcrouse]

These look great, and hopefully they will be case negative.

 

[ZRaffleticket]

Tell me about it... so much easier to work with that way.

 

[Mrcrouse]

Indeed! They are the main reason that my 3 diode hosts can't really be RGB. And I'm sure it would cure so many headaches for serious RGB scanner builders.

 

[ZRaffleticket]

To be honest I'm shocked it's not universally case (+) or case (-)... Something has to be restricting it...

 

[Mrcrouse]

It is quite odd. I wonder if there is a legitimate reason, or if some guy just felt like being an asshole to everyone making RGB's. Or even anyone making green lasers who have to think twice about which direction the battery goes.
