Recessed/ Under-Mounted LED

Kearns892 · June 02, 2010, 02:38:11 PM

I was wanting to try mounting an LED flush to the enclosure, or without a bezel. I tried using some form of coldweld stuff to just kind of glue it in, but that didn't work very well. Tried to search the topic, but I didn't exactly know what to call what I am trying to do, though I am sure you understand what I am getting at. What do you all do?

suspend it by its legs

Haha, good call, however, everything else is done, and the board is not located above the LED. Even if it was, there wouldn't be space to put it there.

Silicone sealant

I've used hot glue to do this.

Maybe you got hot glue to work, I just got a mess...

Don't have any silicone sealant on hand, if nothing else works I may have to try that.

Mount the LED in one of those plastic bezel thingys, and glue the bezel to the underside of the hole.

If you hold the LED there and then glue and hold it until it solidifies, it works fine. I just glued 20 LEDs to the backside of a panel this way a couple weeks ago.

I use a #10 nut drilled out to 5mm.
Epoxy the LED in the nut then epoxy the nut to the enclosure.
Do all this while the epoxy is wet still. Just takes a few seconds.
The dome of the LED is the only part that pokes past the top
of the enclosure.

Start with a piece of perfboard with a couple spacer boards on either side, glue something like 1/2 split of popsickle stick to each of where...
The LED base goes in, the depth of the LED is set by inserting it in the hole, pressing it in by the leads [which are through the slightly raised perfbaord, copper side up, solder the LED in right there, remove the assembly, add dab of glue to the perfboard shims.
Without the shims/feet, the perfboard rocks around, a method of clamping [I used rubber bands around the whole box, then popsickle sticks cut to length to pin the perfboard down on each side.
