New horizons Nichia NUBC31T coming soon 465nm 13W rated!

[Cheech]

Imagine if that MRI accident not to long ago was really some person stealing this magnetic material as a stowaway

Wow very exciting. We saw a huge hornet nest on our roof when we came in yesterday. Had to bust out my 7.5 watt blue Sanwu.. Burned the nest and picked off the little bastards as they flew out from about 10 feet.

I was just going to the Nichia site to look at their list of diodes and apparently they're moving into "other" markets....

LOL
Germany must be having a effect on them.

Man that’s a bummer. I have a project I’ve been contemplating that would require a high powered blue laser diode or even better one of those 95 watt arrays.

To preface this, I’m not one of those bozos who wants to build a laser weapon or walk around lighting stuff on fire.

Wait for it…

An LEP searchlight. I have half a dozen “white laser” LEP flashlights and I’m sure they have low powered blue diodes.

Imagine an LEP powered by 95 watts of beautiful blue photons.

P.s. anyone is welcome to implement this idea first. Just one request - I wanna be the first customer to buy it

Since Nichia decided to hide it for now I will share the datasheet so it doesn't get lost when this device gets reset...
NUBC31T

Update: Nichia has removed the NUBC31T-E datasheet and replaced it with NUBC31T datasheet.

考虑到nubm0g推出并没有太久，在短时间内就将单芯片承受的电流提升一倍是不正常的，因此我猜这其实是两个并联的二极管，以某种方式合束或双光束出光，而这也可以解释封装的变化原因

Considering that nubm0g has not been launched for too long, it is not normal to double the current of a single chip in such a short time. Therefore, I guess these are actually two diodes in parallel, which are combined or double-beamed in some way, which can also explain the change in packaging.

English only please.

All the information so far confirms is a single emitter diode.
The huge difference here this diode has 1.0mm power pins compared to 0.4-0.6mm on normal 9.0mm diodes, allowing more current to flow.
The forward voltage (3.9v) of this diode is one of the lowest seen for its wavelength (465nm) so the efficiency gains and better power handling pins and package can actually allow this diode to easily get 15W+ optical power and even 20W for short bursts but need good quality heatsink and active cooling to dissipate heat quickly.

In pulse mode easily in the kw. Ns pulses that is. I’d like to see this down around 420nm to drive continuum lasers.

 

[RedCowboy]

So...... anyone seen these for sale yet ?

 

[Gryphon]

Anyone have a plan for how they would supply over 10A to this thing in a handheld if we ever do see them? Batteries are easy, I’m curious about a driver solution

Definitely a buck 2 batteries in series. I've been looking for options from single 21700 boost but max i could get is around 7A @ 5V

 

[Dundee]

Um, isn't anyone at least a little frightened of this thing, this kind of power output at 465nm? I mean, maybe you could cut your house in half with the thing, lol.

 

[RedCowboy]

Naw, it's likely just a slightly more efficient diode with a much wider emitting region at the P/N junction.
