I have just salvaged six bare MC-E emitters from a failed vehicle light. I know three of the emitters are still good, while the other three show no signs of damage, but have not yet been tested. I have only worked with emitters mounted on stars previously (and never with MC-E emitters) and would like some advice.
I would like to find some way to work these into either a flashlight or a battery operated work light similar to xxllmm4's ammo can light.
These are bare emitters; what is the best way to mount these on a heat sink surface while isolating the leads from both the heat sink and reflector while allowing clearance for the power leads?
Can anyone recommend a driver or configuration that would allow me to run these connected in series or series/parallel from a 12V gel-cell type battery?
Per the flashlight-wiki article, the max current for this is 700mA. Would a single SSC P7 driver rated @ 2.8 amps be a good match for this emitter with the dies connected in parallel? The MC-E appears to be very similar in design and function to the P7.
Would be better to series connect emitters to a 700mA driver or so. Better thermal safety for multi emitter setups. I would look at having 3 emitters in series with a 700mA Buck driver that runs off 12V. "thermal runaway" is something to look up...
Also some ideas for MC-E with 8*7135 driver http://www.candlepowerforums.com/vb/showthread.php?201392-Poorman-Mutli-Lux-setup-method. Each die can get as much as 0.7A.
They are aftermarket dozer work lights. One of the dozers had an electrical problem and burned out the driver/circuit on the board but at least half of the LEDs are still functional.
