Can anyone help me throw any light on this.
I recently built a small hand held laser. I bought the diode, an LPC 826 diode from odic force
The driver was a round linear 315 ma unit from Mohgasm.
The battery was a single 16340 ultra fire.
the host was a powerlight b50 with a chunky heatsink.
I was told the diode was a 200 to 300 mw unit and recommended current was 200 to 400 ma given adequate heatsinking.
I used careful soldering and heat sink compound around the module and heatsink.
The unit functioned well at first but only gave 125 ma. but it was stable and generated very little warmth that I could detect.
after about an hour or so of trying it out it suddenly dimmed and I think its what experts here may call led Ing.
I should like some ideas of why this may have happened before I try a new diode. any help would be most appreciated.
Many thanks https://www.dropbox.com/s/73vj9f82qhp8dbr/2013-05-13 20.33.31.jpg
