Nichia 144A and 229A series: bigger dies, more output, 90CRI included,.......but no thermal slug :-(

[Texas_Ace]

If you could get some in ~4500k I would grab some for sure (assuming they work good after testing). 3000k is a bit too warm for a flashlight and 5700k a bit too cool. I have come to the conclusion that 4000-5000k is my personal sweet spot.

Obviously this is only if you could get a few extras tossed into your order (I am sure others would buy as well), I do not even remotely expect you to change your planned tints.

Let’s see if I can get mixed CCT with the same MOQ =)

If you could mix the tints a bit I am positive there would be some level of demand for some neutral tint versions with high CRI. How much only depends on the results from testing.

If Djozz could manage to keep a 12V 5700K one alive, i’d be very interested.
…actually also very interested in a 3000K one…
(but i’m probably not the only one…)

[edit]
6V is fine too.

Good news guys!
I just spoke to Nichia sales person, and I can mix the CCT and voltage for my next order. Hooray
Please vote your preferred CCT and voltage in my recent poll

Sounds good! Have you asked about the 219c 90+ CRI versions that are supposed to be released now? Seems they are available up to 4500-5000k? according to the data sheet, if you can mix and match I know there are a lot of people that would like some 90+ CRI 219C’s.

Link to poll?

No, it’s confirmed that the 219C Ra9050 only available in 3000K. If you look at the website the rest of the CCT only available in Ra8000. (corrected by Maukka). I asked my local Nichia representative

I know, asked for it many times. And the answers always negative. I just called him yesterday.
Still not ready yet. They said “maybe” next year

Oh well, it was worth a shot. Depending on price I would still be down for some 219’s as well though, I am really liking tint mixing lately and 80+ CRI tint mixed lights look quite good as well.

A little more 144A info:

• Emitting area: 4x4mm (16mm2) - same configuration as a XHP35 (with lower forward voltage)?
  
• Aluminium Nitride substrate (285 W/(m·K))
  
• Gold contacts

Distributor of the brand Nichia in Italy, *Welt Electronic* presents the new multichip series 144A. Nichia, a company of the first
magnitude in the products Mid Power and High Power, deals with the application market outdoor, street and tunnel lighting,
with a multichip Super Hight Power consists of four chips of 2 mm2, close to each other and arranged in a square: a plus optically unequaled.

These are the characteristics of the series 144A: Aluminium Nitride substrate, a component that increases the efficiency and
lowers the thermal resistance; Nichia Flip - Chip technology, which eliminates the process of wire bonding as a connection between the anode and cathode, presents a critical element in less than the technologies adopted by
other manufacturers; gold electrodes, which allow not to decay in application, because it is completely free from corrosion in an
environment saturated

Alumininium nitrite looks like the way to go creating a board for mounting these.. it should be reasonably cheap to have someone make a bunch of 16 and 20mm disks... then glue two pieces of copper sheet to the top to act as electrodes. Done.

Welt Electronics sounds like one possible source.

Who's gonna request a quote for a big box of standard 16 and 20mm boards with multiple wire contact points and thick copper traces to these guys? O:)

You’re right. I edited my post. Well maybe other Nichia distributors have it. I asked the Sout East Asia distributor in Singapore via Indonesian representative.

Very nice, if you can get these for a good price I would get a few, I do prefer 4500k myself so it would keep me from stocking up.

[leaftye]

I can’t wait to see the test results.

The 144A test results? Djozz output test here and maukka CRI test here.
