Yes, not so interesting stuff for you guys. Will requires specially made PCB. The anode - cathode separation is only 0,2mm! Just a LITTLE too much solder and they will bridged. Keeping 2 or more emitters perfectly parallel and flat is another challenge. I didn’t use tweezer as it’s only 0,2mm thick, and the coating is very fragile. The soft silicone protection coating has phosphors mixed in it (warmer CCT/higher CRI has thicker coatings). I just dragged it here and there using fine feeler gauge blade.
Imagine (manually) creating a light panel consists of 100’s of these… :confounded: :disappointed:
Ladies and Gentlemen…. the awards goes to Chouster and Texas_Ace….
I only did two big bulk packings
Guys, please let me know about the colour of 219C 9050 sm503. Mustsimon said it’s pretty green (even though he compared it to some of his 219B’s collection). I don’t have any yellow/green or even yelloish/greenish problem with them all.
Those sm503 9050 219C and sm573 9050 144A are by far the most neutral white I have.
The more current, the (slightly) rosier 9050 219C becomes
Those E21A are very interesting. Imagine a 20mm triple under Carclo optics. Unfortunately this would need a special MCPCB. For good heat transfer a special AlN Board would be nice, or a direct cathode MCPCB combined with a special driver that switches battery+, so that the board wouldn’t have to be isolated.
3x E21A and Carclo 10511 should make a very nice beam, smooth but with some throw.
That beeing said, I would expect the NCSL219B-V1 R9080 to be quite similar concerning beam characteristics under those 105xx Carclos, but much easier to implement.
I just built up a Convoy S2 using one of the sm503 9050 219C. Looks pretty nice to my eyes, but it’s hard for me to tell as I’m red/green colorblind. I wouldn’t mess with high CRI for myself, this is for a friend who will enjoy the CRI. It does appear to be a wonderfully neutral white though.
Thx for the AlN idea Chouster, will think about it.
Carclo 10511 designed favourably towards Cree XP-G in the first place (0,73mm focal plane). The rest of the emitters will need some adjustment in optics’s peg height. E21A paired with 10511 isn’t as tight as it potentially could. The problem lies in much lower focal plane in E21A 0,27 - 0,3mm +/- 0,05mm (height vary with different CRI). Compare this to 0,4mm in NVSx219C/NCSx219B-V1/NVSx219B-V1.
We all know that domeless emitter with the same die shape should have much tighter beam. But from this beamshots, the difference is only marginal. Approx. 1 degree tighter compared to 219C (the same die as E21A).
Cree XP-L HI usually have ~20% tighter beam compared to XP-L HD in any TIR optics.
Yes, I got them pics from Carclo’s website.
I don’t think they mixed it with NCSL, it’s what it is.
Beam angle order in 10511: 219B - E17A - E21A - 219C - 319A (weird huh?)
If we follow common sense based on die area geometries it supposed to be like this: E17A - E21A - 219B - 219C - 319A
So far, the only explanation logcal to me is in their focal plane (die height) differences. Anything lower than ~ 0,6mm - 0,73mm (XPG) will off focus. 219B, 219C, and 319A are all have 0,4mm focal plane. That’s why their sequence looks OK.
We were talking about 10511. And in that particular optics the cd/lm number looks normal.
The latter optics you posted indeed has too much difference for such a slight difference in die area (219C vs. 219B)
Yup, that’s right. Sorry, I was talking about the 10511 indeed. But when I looked at the numbers from other optics that’s when I realized that something isn’t right about those numbers. Not that clear when you just look at the 10511’s numbers.
Swapped xpg3 90cri out for nichia 219C sm503 in a triple x6 and it looks great with no green. As noted by TA, maybe slight blue if you are sensitive to CW but in general a very pure white.
The 4000k is just slightly warmer than I like and the 5000k slightly cooler. I’m going to try 2 of each when I rebuild my s41 and see how that turns out.
Thanks Illuminos for the report. I just want to know who else got the green other than Mustsimon.
How is it compared to XPG3 90CRI? I mean real world colour reproduction?
