Hi guys,
not long ago i was asking for help in the headlights subforum to get a new one with adjustable output (i want one which doesn’t blind me when i climb on the boulder wall). There were some nice suggestions, but then i thought if it would be possible to mod one of the lights i already own, because is very light and comfortable but i’m not using it very often anyway. It is one like this one:
(yeah, i know about the weird smile of the guy…) 1W led, build quality is decent, but i have no clue if i could add some part (preferably in the cable section) to regulate the output. I’ve been using the search function in the forum, as well as google, without success.
Any suggestions for the mod? any help will be highly appreciated.
Thanks in advance
Possibly a resistor on or in the battery pack. Possibly a variable resistor. Or maybe just a diffuser on the LED housing.
LEDs are constant current devices, so reducing Vin isn’t going to have any effect unless the LED is direct driven (that is, without a constant current driver). To be able to change output levels on the fly, you’ll need a driver that can vary output current and to suggest which one might suit your application, more information would be very helpful. Particularly the battery configuration, what the existing driver looks like, pictures of the inside of the light unit, if that’s where the driver is (I’m guessing so, as the button is there).
To be honest, unless it uses a fairly standard driver design, it would be easier to simply buy a new one or slap some scotch tape over this one.
Ramping Driver?
I’m so sorry to run off-topic but I can’t stop laughing about the creeper in that photo. He looks like the guy walking around your neighborhood at dusk, asking all the kids for help finding his lost puppy. “I know he likes to go into these woods over here, would you come give me a hand?”
dragging it further off topic, but having small kids, I don’t find that kind of thing funny at all.
Unfortunately, there will always be creepy ill-meaning people in the world. Whether or not they are laughed about won’t change that they exist…
of course, but neither does it prevent me from expressing my displeasure at it…
Thank you all guys for your help, both in and off-topic. I’ll try to find my camera, which is not much better than my smartphone crappy one so i can post the pics. Why is :bigsmile: :bigsmile: life so tough !!!
