Default LED mounting

Everyone likes nice shiny LEDs on their gear! What are the different ways you guys have used to mount the LEDs on the chassis?

I made and LM3887 dual mono amp. I have been trying to find a good way to mount the LEDs, one for each power supplies, to the chassis. I have a bare face, just two 1/64" holes evenly spaced for each supply. The goal is to have the LED behind the hole but not right on top of it.

Any suggestions?

What other methods do you use for other types of lighting?

Mods, if there is a similar thread please merge.

I usually try to get the so called "cylindrical Leds" as in the picture:

I you get those leds, mounting them is dead simple: just a hole with the righ diameter and a couple of drops of glue to fix them at the same level as the surface of your box.

You can buy bezels for LED's.
Most electronic suppliers sell them.

I drill a tiny (1mm) hole from the front and then a suitable one from the rear leaving 1-2mm of the original 'pilot' hole. That way the light is visible but not too bright and noticeable.

Hope they might help?

Hi,
You can use led mounting clips. Do a Google "Led Mounting Clip".

For one of my recent projects, I seriously considered making a small hole in the front panel and attaching a clear plastic "window" on the rear side. The LED was then to be PCB-mounted with the rest of the circuitry, creating just a glow in the window. Seems like a workable idea. I ended up, though, just using a LED mounting bezel. About 2mA was enough illumination so it is easily seen under-lights/in-daytime, although it is just a grab bag standard 5mm green LED.

What is your source on these? Looks like what i am looking for, mounting flush to the rear of the panel .

I always use these R9-104L by Shin Chin. Very handsome and they come in a wide variety of colors. Mouser sells them.

If I could I would try and get laser perforations a la Apple products, but I feel like that would be cost prohibitive.

t4ckleb0x:

On several projects that involved HiFi2000 enclosures with 10mm front panels, I have drilled (or had Front Panel Express drill) a 3mm hole most, but not all, of the way through the panel from the rear face. On the front side, I have drilled a 1mm hole. Gluing a 3mm LED into the rear of the front panel is easy, and the small hole on the front is just large enough to be noticeable.

The photos show my daughter's LM3886 amp. There are LEDs mounted behind the knobs for backlighting and another above the switch.

Regards,
Scott
