Most effecient chips!

[ChiefRunningPhist]

I'm looking for the most electrically effecient 0-3w chips. Im looking for the chips that produce the least % of waste energy or heat. I'm not looking for the best μmol/j, although I'll take it if you have it.

These are the peak wavelengths I'm after and I would prefer a wider band than a really narrow band....

- 420nm
- 445nm Osram square - 72%
- 480nm -
(Or a wide blue phosphored chip?)

- 525nm - Nichia (1717) - ?
(Been looking at Nichia and others but can't find an effeciency metric. I might have to compare lumens/watt for this chip)

- 600nm - Osram square - ?
- 630nm - Osram square - ?
- 660nm - Osram square - 66%
- 730nm - Osram square - 56%

I'm having a difficulty finding the effeciency % on the chips. If anyone knows of any chips that I have shown here next to an "empty blank," or can correct my current entries with better effeciency % chips, or add similar chips of similar %, or can give % effeciency measurements of any of the chips, please speak up!

Super dope custom cutter strips in the future sounds like you're after!

I'm looking for the most electrically effecient 0-3w chips. Im looking for the chips that produce the least % of waste energy or heat. I'm not looking for the best μmol/j, although I'll take it if you have it.

for a given color/spectrum, using umol/J or efficiency % are the exact same thing (just different units)

Right, but while some of the peaks of the chips may be identical the range may differ, that's why I I'm ok if you have μmol/j but would rather the electrical effeciency..

 

[CobKits]

datasheets should have efficiency, but its usually expressed in mW output for monos

efficiency = mW output/mW input

 

[OneHitDone]

datasheets should have efficiency, but its usually expressed in mW output for monos

efficiency = mW output/mW input

This is how spd's should probably be presented as well. So the end user understands how much power your getting at each nm

 

[ChiefRunningPhist]

efficiency = mW output/mW input

Ya most FR mono and/or UV do mW, but the more visible the WV it seems they all do in lumens (sunplus and osram provide μmol/j too), and I can't find effeciencies. I've all the Osram data sheets, all the Nichia data sheets, some of the sunplus line,... and some effeciencies are shown on the Osrams, but I can't find any on the Nichias, but that's as far as I know too...

EDIT:
And because they aren't lasers, they do have some variability and range of SPD, simply dividing by the equivalent peak WV energy won't be 100% accurate.

Here's a link talking about that a bit...

It seems a normal expected metric to provide?? Maybe I'm just missing it??...

@TEKNIK do you have the % effeciency of that 450nm Nichia blue?

 

[whytewidow]

@TEKNIK do you have the % effeciency of that 450nm Nichia blue?

I'm also interested in this. Great thread @ChiefRunningPhist

 

[ChiefRunningPhist]

I think you might be able to just invert a parabola, and find the resulting area that its taking up, and use this figure to realize the theoretical maximum efficiency of the particular SPD... Mono could be achieved I think relatively easy, white with varying peaks ect I think would be a little harder..

Derive an inverse parabolic function to model the particular SPD, and then integrate it but set the limits equal to the μmol/j of the particular WV at the upper and lower bounds of the SPD?

Any math guys out there? Is this right? I guess I could just test and find out..


EDIT:
On another note, I think I can extrapolate with some proximity electrical effeciency based on lumen count and this chart...

Pretty sure he got banned for being a non grower.

I get along with him but he does pick a lot of fights.. Thanks for the update either way.

I'm not banned yet, they just made a complete mess of my account here to make it near impossible to write anything. I guess that will keep some of you happy that dont like me.

shit just when i was warming up to your aussie ways!.....

good thread chiefrunningphist.

 

[ChiefRunningPhist]

So how about that 450nm Nichia data??

 

[ChiefRunningPhist]

These are the peak wavelengths I'm after and I would prefer a wider band than a really narrow band....

- 420nm
- 445nm Osram square - 72%
- 480nm -
(Or a wide blue phosphored chip?)

- 525nm -
(Been looking at Nichia and others but can't find an effeciency metric. I might have to compare lumens/watt for this chip)

- 600nm -
- 630nm -
- 660nm - Osram square - 66%
- 730nm - Osram square - 56%

- 420nm
- 445nm Osram square - 72%
- 480nm -
(Or a wide blue phosphored chip?)

- 525nm - Nichia (1717) - 41%

- 600nm -
- 630nm -
- 660nm - Osram square - 66%
- 730nm - Osram square - 56%

*Updated the 525nm to a Nichia 1717, @ 41%.

If you can fill in any of these blanks, or can amend current models with better ones, quote the post and reply with any updated fields. Thanks

No.

An upside down parabola is close but the correct function is that of a Gaussian...

So you just have to play around with the equation, changing h & σ and changing graph position and such to mimic a close representation to what SPD you're looking at. Then you integrate it over the WV range with respect to photon effeciency per WV or lumen effeciency multipled by a conversion factor per WV.

I think that's how you say it, and I think that's how you'd find maximum effeciency for an SPD. Its been awhile and I can't remember exactly. Feel free to step in if you know what's up. @alesh

But then after maximum effeciency was found you could divide recorded effeciency by it to get total radiometric effeciency.

And I think I was wrong earlier. I think I was putting too much emphasis on accuracy for the data supplied in the data sheets. I think just dividing the measured output by the peak WV maximal output, is as close as you can reasonably get to accurately calculating effeciency given the info on the data sheets. At least as far as monos are concerned, you may as well treat them as lasers.

When I checked this reasoning with the 725nm Osrams and found it to be within ~+/-2% depending on bin when calculated using the "laser" method, it matched the same variability of mW output/mW input to the stated effeciency on the title page bullet point. So imo they are interchangeable methods.

As far as duplicating curve functions, I think it could be beneficial for determining effeciency of the lumen rated chips, and also just for the mental jog, but for me it's turning into a mental marathon lol and I need to shmoke a bowl

I went with 60 of the Osram square 660 nm (hyper red) ordered.
I am happy with price and spec.
Now blue plug and play Osram 445nm Osram square chips I can not find online for sale.
I would love to try the 445nm Osram square.


So what about if you tune er yourself?
Check this out!
