Pictures of some emitters

Just took some pictures of a couple of emitters, first out is the beloved Cree XR-E in the wild:

 

xre's

Notice the copper colored border around the newer and smaller EZ900 die, right slide showing an antique XR-E with the phosphor sprayed everywhere.

 

Next up is a XR-C posing next to the older XR-E:

 

xr-c

Differences includes a smaller die and half as many bond wires.

 

Poor cool white XP-E, got extracted and replaced from within a Trustfire F-23.

 

xp-e

Die looks the same as in the EZ900 XR-E but there is no copper border present around it.

 

A couple pictures showing emitters in captivity:

 

TF F23

TF R5-A3

Q123squared

QminiAA

Tell tale differences between XP-E and XP-G includes the number of segments the die is divided in, three vs four, the difference in die size and the absence of the three dark dots around the XP-G die.

 

Last but not least, a newer addition to the zoo, a Luminus SST-50 (actually a SSR-50, but they look the same anyway)

Thanks Spambot for this excellent contribution! An excellent reference here for all of us. Very well done. Frontpage'd and Sticky'd.

By any chance could you include a picture of a light with an XR-C? The XR-C appears to be a popular choice for manufacturers when they decide to "get cheap" with a popular product that used to have a more modern emitter.

This is an SSC P4 LED - T bin AFAIR. Because of the "cloudy" dome it is a pig to photograph

This comes in a lot of ultra-budget lights. It is quite distinctive in appearance.

This is an M bin Cree MC-E.

Bright!

 

And here's an older MC-E, J or K bin

Been playing with the not terribly useful USB "Microsocope". It probably works rather better with the supplied Windows software but the Windows box is getting annoyigly noisy - time to swap out some fans.

For decent, if small,  emitter photos you can use digikey.

These are what appear to be in the DaZong Tong tiny little light. Still not figured out how to extract the TIR optic without killing it but my best guess is that these are the LEDs in it.

 

Strange little light

Is this warm glow a property of high CRI or just any T4? I thought UV light would make all phosphors glow.

Thats odd. Do you know the wavelength of your UV?
Is that how it looks to your eye? My eye sees more phosphor glow, less blue / uv then my camera.

According the StreamLight site, it’s 365 NM. It seems to be in a good range because different denominations of paper money show different colors clearly. Other “UV” lights I tried didn’t work as well.

Yes, that’s exactly how they look. The T4 glows brighter if I move the UV closer while the U2 does nothing.

They always seem to use blue leds under the phosphor so its looks like in maximizing it for blue the cool white just doesn’t luminesce as low as 365.
Streamlight Stylus UV ?

That’s the one.

With a cheap (unknown wavelength) UV light, the U2 barely glows white but still nowhere near as bright as the T4 under the same light.

Does your cheap UV light put out a lot of purple? Light yellow glasses cut the purple really well. Plus protects your eyes. Damage is cumulative.



Mouseover, XM-L CW vs XP-G2 3C
Three images: Initial UV, mouseout white, mouseover UV with yellow camera filter. (initial UV image only returns on page reload) Doesn’t show the dramatic tint difference that can be seen by eye. Also brighter by eye.

UV is about 400-410nm. ‘1W’ emitter in an Ultrafire WF-602C 1*AAA both from dx many years ago.

Yes, it’s very purple. I don’t have yellow glasses but your image without the filter looks about the same (maybe a little brighter) as what I’m seeing.
