Emisar D1S Oslon Black flat mod 340k+cd

I just finished up modding my D1S with a Oslon black flat , all i did was reflow the LED on to the xp board that came in the light. I put the MCPCB back into the light, shaved down the centering ring to fit the new LED and viola it worked!, it now produces 345kcd and ~707 lumens comapred to the 140kcd and 1200 lumens. LAZER BEAM TIME

Some Pictures, a video will be up soon @ https://www.youtube.com/channel/UCcWcPSMe1ohtcYf3BHsaldA?

Nice. Is that the D1S with XPL HI in the comparison shots?

I always thought those were very expensive but I guess not, quite a surprise at under $5..
That is just awesome, you should be able to light up some satellites going by with that D1S..

I thought the Oslon black flat were weird to feed, like with a P-Fet or something Davie

wait, isn’t Stock MCPCB is DTP
did you also change the driver?

“shaved down the centering ring to fit the new LED”

What do you mean by shave down? Because the LED is sitting lower than the XP-L HI?

The data sheet Vf is 2.75(min) 3.05V(typ) 3.75V(max) at 1amp. Rated forward current is 50-1500mA. Maximum rated pulse current is 2.5A.

He’s talking about the thermal pad not being electrically insulated.

So, any explanation ?
Is it as simple as a reflow on the stock Noctigon and voilà ?

My best guess:
A lot of non-conductive thermal paste was used and the DTP-MCPCB is just isolated from the driver by sheer luck.

Otherwise you would need an isolated MCPCB as those from led4power which use a special aluminium oxide layer to have near DTP-performance on isolated MCPCBs

Yeah I was thinking the same… Heat path is not ideal in that case Sad

This might be 100% wrong. But I vaguely remember someone saying that the Emisar boards have a P-FET?

Very cool build mikelights.  Congrats

This might be the same emitter at Arrow for lower cost and free overnight shipping:

EDIT:  I just read here that there are what sounds like higher binned ones at mouser and digikey, but I can't seem to find them.  I can't seem to match up the manufacture's part number to the datasheet.  The listed specs appear to indicated the highest light output, but also highest Vf.  They are only showing max's though.  So not sure about that.

EDIT2: Please disregard the struck out text.  Member Nicolicous alerted in Post 31 below that this is a 5-pin package that may not be compatible with XP based.

The Emisar lights don’t have a p-fet driver .

The explanation : the driver’s ground , isn’t connected (electrically) to the head , but only the tube is , that carries the Battery (-) .
That allows the head to be connected with Led (-) without causing issues on the driver .

Annnnnd thank you very much for that clear explanation, I couldn’t for the life of me figure how it was possible.
You couldn’t do that in, say, a C8…
Now I have to order some black flat Facepalm

True about the head being isolated from battery negative. I didn’t think of that. But I wouldn’t necessarily rely on this method of isolation because if the anodization of the tube threads wears off it’s no longer isolated.

A method to isolate the MCPCB from the shelf that’s worked well for me when I was experimenting with making XD16 arrays is using narrow strips of kapton as spacers under the MCPCB. A couple small strips (~2mm x 15mm) near opposite edges of the MCPCB prevent any metal to metal contact. Put the strips on the MCPCB and use ceramic thermal paste as usual. The kapton thickness is only 50microns so it’s practically not adding any thickness to the thermal paste junction.

This is a rare occasion , since most people change battery from the tailcap side . Someone could add some (veeery little) medium strength threadlocker to be sure they won’t change battery from this side , and so it won’t wear off .

Yes but since the head isnt electrically connected to the driver I didnt need to change anything except reflow the LED.

I had to sand down the little centering ring for the led to get optimum focus and shave it out a bit to make the hole bigger so the black flat would fit, the black flat is a bit wider than the XP-L HI

simply put yes it is, I was expecting to have to isolate the MCPCB but I didn’t have to because of the isolation between the head and driver which made the build process a lot easier and quicker

originally I was going to use thermal epoxy on the bottom of the driver to isolate it but I didn’t need to because of the driver isolation, but my solution is not to unscrew the body from the head just use the tail cap which keeps the threads from ever getting worn down.

That link is for “Automotive 5-Pin SMD T/R”….I don’t think it can reflow to your xpl mcbpc.

Arrow do have 2 -pin but not in stock. I got their email reply of 10 pieces for $21…. Seems good deal

Think I’ll pull the trigger soon Smile
