Kyocera lep emitter

DIgikeys inventory quantity has increased for both the bare and star mounted emitter, unfortunately, only for the "500lm" type. I'll keep an eye out for changes periodically. The format is quite large, especially in height compared to most LEDs, which limits its potential compatibility with optics. Baja designs shows models with an open bucket reflector, which may also be simpler to focus with, as compared to the apparent TIR offered by Rogid's offering.

I have a small number of diode dynamics driving light optics on hand, I'll see what diameter their base opening is. I believe they use the same optic assembly for all three of their LED offerings in their "SS3" pod lamp, which is available an osram boost hxb emitter, a cree xpl-hi, or a lumileds chip. My assumption is the kyocera will be too large across its maximum width to sit down over the kyocera package, and thus won't be able to focus.
 
FYI. The Kyocera SMD LEP package was groundbreaking at its release but is at least four years old by now. It's strictly limited in output and unfortunately wasn't adopted into major automakers headlight design. Only a few aftermarket auxiliary light manufacturers.

The preeminent manufacturer of LEP engines for OEM applications of a wide variety of designs including automotive is a Chinese company known as Blue Lake Laser. They have modules of various sizes and outputs from 30 to well over 100W for double digit megacandela searchlight applications.

Five years ago they were the LEP module suppliers to Acebeam for their groundbreaking W30 and powerhouse W50 LEP flashlights. They still offer those modules (as the least powerful).

You should peruse their OEM website, albeit it has a funny sounding DBA.....


They offer module kits (LEP engine and optics) to prototype your own design flashlights or headlights. Just add your own housing and power supply. This is an absolute golden opportunity for someone here to put together an experimental hand held uber searchlight. The components for the "heavy artillery" module kits are around $2k. Not cheap, but a chance to create something unique and obnoxiously powerful like the Wild West of hot wire incandescent custom lights decades ago.

If I had the fabrication skills I'd have made one already. I hope some brave soul here rises to the challenge.
 
Looks like Mouser has it listed on its site. Maybe it'll start selling/distributing the module in the future?
The color over angle out of these emitters is painful, I had a chance to play with one a few years ago and I realized it's half white light and 3/4 blue light leaking out. Still waiting for this technology to improve. You can see in the white image where the blue artifacts are just bleeding everywhere. You can also see where the lasers shine on the phosphor and aren't really shielded.

Wow, very interesting. They even offer 90+ CRI offerings that have higher surface intensity than the osram white flat chips. And some with rectangular emitting surfaces. Very neat technology. Thank you for the information!

Do you just contact them with a case for paying for an r&d lightsource and documentation? I assume there are some contracts/nda type agreements that would limit your ability to post on a public forum about any testing or project with them.

@foxtrot824
Oof. That pic is not very pleasant. Have you had any opportunity to see them in the past 4 years? I imagine in that time they would have had some improvements over their initial release, even just some small refinements.

Unfortunately I haven't not seen anything modern up close. I'd imagine someone figured out how to better mask the blue pump source by this point. I think efficiency is still the challenge. It's essentially a remote phosphor setup and those can be tricky when it comes to reflecting all of the light.
 


I am cross-posting this from the laser headlight thread in the automotive lighting subforum.

The units are very inexpensive on ebay, but require an external power supply and need to be externally cooled at its rated power input level, both for the laser unit and the remote phosphor.

The beam pattern appears much more coherent/well formed than I would have assumed from what appears to be a very small reflector assembly. Very interesting to see.
