 Posted: Mon Jan 07, 2008 12:59 pm Post subject: Question about Annunciating Lights |
 |
|
I have a really great idea for the panel of our RV and I wanted to solicit some help from the liters out there. We are using the dual screen AFS-3500 for our panel and I wanted to create an annunciator panel to sit next to the AFS in a vertical config. Here is my idea…
Picture if you will a dual screen AFS setup in an RV-7A panel with a radio stack just slightly right of the middle. Just to the left of the radio stack and just to the right of the pilot side AFS is an annunciator panel with the following dimensions: 7” tall and 1.5” wide. There are approximately 12 individual annunciated items (pick what you want). The visible part of the annunciator panel itself is a reverse engraved acrylic installed in the panel.
Here is the problem:
I am looking for a method or product to “cage” the LED lighting for each individual annunciator. So when one lights up, you do not get bleed over light into an annunciator above or below the one that is lit.
I have the wiring, connectors and case already laid out on paper and that is not my problem and this is not the issue; my only stumbling block is a way to ‘cage’ the lights behind the acrylic panel that is visible.
Does anyone out there know of a company or have an idea of a product to use to accomplish the caging of the lights only?

Get access to a milling machine and carve out an
"egg crate" structure to go between the back of
your panel overlay and the etched circuit board
holding the LEDS.
I just added a mortise drill to my woodworking toys
in Medicine Lodge. This thing cuts square holes.
In fact, the machine I bought is now on sale at
http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=35570
It seems that some reasonably machinable plastic
or hard fiber material could be "machined" with
this simple tool to achieve what you want.
The one I did for a customer was an aluminum pattern
from which silicone rubber molds were cast. The molds
were then used to vacuum cast epoxy forms that made up
the egg-crate structure for the lamp pockets, front
panel escutcheon, pocket for engraved overlay for
legends and etched circuit board on the back.
This tool cost a couple of grand to but it was
used to make a fist full of nice parts.
For a one-of-a-kind project, you might consider
the mortise cutter as a good starting point. I'll
play with this idea a bit when I get back to the
shop. I've got a lot of walnut and oak that might
just be hard enough and machineable enough to
do the job.

Got a picture?
Why do you need 12 enunciators? Doesn't the AFS do this already?
I did just a few using legend lights from aircraft spruce. I modified some spare bulbs I had already and made them into led bulbs. You can also buy pre-made led bulbs in this format. works good. Attached is a picture of the final result.

Bob, Good luck getting your mortising bit to cut through hard woods. These
things are made for softer woods but if you keep the cutter edges sharp they
will do a much better job. They ALL must be honed when you get them new...

Scott,
You could try thin brass stock (hobby shop). It is easily bent and
soldered. I used some LED lighted push buttons that I'm not sure that I
like. The panel is a small radio width panel at the top of my stack so
It may get rebuilt but not before I fly!!

I've had pretty good performance in walnut but I've not
yet explored the tools/talents to keep them sharp.
I'm thinking a machining-friendly plastic like Delrin
would be a good starting point. I've got some scraps
to try on the next trip.

Look at some of those "Daily Dose" medicine organizers at the drug
|
store. They have little compartments for each day of the week. Might
find something similar in a bait'n'tackle shop.
Another option is to get a strip of 1/4" plexiglass or even black
delrin. A 3/16" bit will drill a hole that is a push fit for a 5mm
LED. The 10 degree spread LED won't bleed over into adjacent areas much.

I'm building an annunciator strip as well. I'm planning to get some plastic
strips from a hobby or craft shop and glue together an appropriate egg crate
to isolate mine. Mine has a smoked acrylic cover so I may glue or RTV the
egg crate to it or the overlay for a good seal.

How about the egg crate style fluorescent light fixture that is often
used in place of the frosted panels ?

Everyone...Thank you for all of the responses and suggestions. It looks
like I will need to hit the aviation section at Home Depot again. Although,
sometimes the aviation section at Lowe's is better.
The idea with the U-channel is an excellent one, I wish I had thought of it
sooner. If I can find a piece of the right size, it should work out nicely.
I did contact Paul off-list but did not know the thread existed on VAF.
Thank you for the link. I think I have solved my problem.
I still need to go buy a band saw anyways; that however is a heck of a lot
cheaper than what I was quoted from Statcoswitch for a lighted indicator
matrix.

I made my panel out of Honeywell microswitches. It's not really a cheap way,
but the results are nice, and it's fairly straight-forward, with "dead face"
(labels so you KNOW the lamp is out, because it cannot be read unless
illuminated from behind). I also built a push-to-test circuit.
