If this were my project I would want to be able to move the lighting on the inside. You may find "HOT" spots in certain areas. And you did say you will be anal or for those that are dyslexic "lana". Anyways, whenever I do under counter lighting I always adjust the lights for best effect by moving it in or out. You could even make silhouettes to change the look of the picture. That would be cool.
Small crafty project: Custom LED backlit 40"x60" frame for a canvas
5
So I am a total noob to this forum (I hope this is an appropriate section given the different aspects of this project - granted it is not home renovation lol) and have a thread for this project on a bit art forum - and I have gotten some input there as far as construction of this lil thing goes but nothing much indepth.
I am also a noob to woodworking and electrical stuff.
Therefore this is a fun project for me to learn a few basic principles by practicing on this initial project I plan to keep up this creative building angle as I am collecting fun tools and stuff along the way.
ANYWAY - here is the progress and plan so far:
I have the backing framed out and with the plywood on it - I just got done doing my first machine sanding to the edges to make it fit flush and just a tiny bit recessed from the canvas. I test fit the canvas on the frame and made notes of where I need to focus on the next round of sanding to make it uniform (I am nitpicking this thing lol).
The interior will get white paint and the outside borders a satin/gloss black. Oh and some venting holes for the leds so heat isn't kept in the chamber.
So here are some pictures of how it stands now, I put the powersupply and dimmer and reel of leds in one of the pix so you could see what I am gonna work with electrically. I will need to figure out how to properly cut the reel into two 4.5' sections wired up to the dimmer and powersupply.
---So the biggest remaining issues with this project that I need input on are:
-Light diffusion (and sort of wiring)
-LED installation (how to cut the 15' section into two 4.5' sections wired to the dimmer and powersupply)
-Wall mounting style (I am thinking some sort of long metal "male" bit bolted on and then the "female" bit bolted to wall studs for installation)
-Canvas to light frame mounting (should I simply bolt it on, heavy duty velcro lol - or what????)
-Dimmer placement (I am thinking the adjustment nob should just poke out the backside of the painting so perhaps use bolts/nuts with washers or wood to shim it a bit into the inside chamber..... though maybe I ought to wire it in a way that a ~8ft wire simply exits the chamber and runs to the dimmer and powersupply made into an array or something at the end where it plugs into a wall socket).
ANYWAYS... just rambling out the plan - I think light diffusion is the biggest issue im confused on because I don't want obvious light hotspots because I am not using the LED's to border light the whole thing, I am using them inside the "chamber" to backlight the image like a XRAY projection or whatever

I would REALLY appreciate any input you guys can give me on this little project - even just links to relevant info you think would help me... or just your opinion on whatever
thanks for reading and checking this out :thumbup:

Wow!!! You sure like to throw a bit of paint around judging by your studio
Either that or you have exploding paint cans lol
Looks great but can't help with the lighting. Look forward to seeing what you come up with though.
Cheers

I work for a sign manufacturer. On our internally illuminated projects, we'll often use a light dispersion film applied to the inside of the panel to eliminate "hot spots". That would help give you more consistent illumination.
Endurance sportscar racing teams are required to illuminate the car # during the night hours of the race. They use a thin Electroluminescent panel that is lightweight, low temp, and with low power requirements. I don't know much about cost or standard sizing, but it could potentially simplify your install if you're not committed to LED.

You might want to think about using a piece of diffusing film.
Could stick it to a super thin piece of plexiglass...
It would create a more even light.
You can even order "Milky White" Plexiglass...
This guy used to to make a movie poster, and used it to diffuse the led rope

thanks for all the input and comments!
soooo last night I ended up ordering a few rolls of this: https://www.inventables.com/technologies/light-diffuser-film-rolls
I hope it works well
So I am getting closer to having this thing done.
I'm still scratching my head about how to mount it up on a wall (male/female brackets? some kind of slider? etc? I dunno) and how to get the painting on the light fixture part nicely and with the option of removing it fairly cleanly (I've been thinking about velcro tape stapled on...)
anywho - hopefully I will have the lights wired up and the test fit with the diffuser stuff soon

I think you would be better off using 5050-3012 and lighting from the edge, as long as the led's are covered so you can't see them. An inline controller would also be easier to install/conceal, better yet an inline remote controller and RGB lights so you can change the color. Sorry about the pic quality, the first one is the inline RGB controller, pretty much the same as the second pic, which is just a single color inline controller, but it has a credit card sized RF remote controller.

thanks for the input and info, but with this project I am just gonna stick with what I have now - a controller would be cool, next thing I do I will try with that but with this one all I need is dimming adjustments no color changes really.
these are the electronics I have:

that is the reel.... it indicates that every three diodes you can cut (has a little scissors image)..... so I want to make three sections of 4ft long cuts from that 16ft reel, I need to wire them all together then altogether to the dimmer then to the transformer which plugs into the wall. I want to have the wiring exit the chamber they will be installed in together as one strand if possible, which will need to be about 8ft long and at its end attaches to a little array I will bolt the dimmer and transformer to and hide where I plug the transformers little cord into a wall socket.
I want advice on this, like what gauge of wiring and type I should use and so on... I am a noob to all of this stuff, I have a cheap soldering iron I dunno if I am going to need it - I need advice! so really basic noob to wiring electrical advice would be sooooooooooooo nice
anyway any input on how I should tackle this would be greatly appreciated
:wink:
ps. my diffusing material should be here tomorrow

awesome guys! thanks for the info kevin and wayne - really appreciate it
the last thing I am wondering is when I have all 3 sections wired up I need to connect all 3 to one wire that will lead to the dimmer - how should I setup the connection of all 3 section's wiring all into one wire? those little cone things? heh - and 18awg b/r stranded is ok to use for the whole thing on this?
sorry for being so noobie
thanks again!
(watching a LED tutorial on youtube helped my confidence level - good recommendation there!)

soooo I finally have an update for this, finally got the LEDs wired up.
here are some pictures of how it sits now.
soon I plan to staple down all the wiring and have it exit out a hole I drilled in the back all nice and clean... I am thinking I will also staple some on the LED strips themselves as I dont want the adhesive to fail and them flop around in there sometime in the future.
Anyway, besides that I am gonna drill some vent holes and paint the exterior edges black or white (can't decide)
I think from what I have seen from my test run that I actually don't need any diffusing screens - I just need to modify my canvas before I secure it on... that is cut out the frame supports. I am thinking I will use L brackets in all four corners to supplement some support for the hell of it.
sooo
big question is if I should just simply screw on the canvas to the chamber with screws from the backside or do something a bit more thoughtful.
another big question is how I will create a mounting system for it to easily go onto a wall (gonna have to screw into the studs as this is a bit heavy)
finally I need to bolt the transformer and dimmer onto a lil piece of wood or something so its secure and can just hide behind something fairly easily (I have about 9ft of wire to run out of the chamber to the dimmer/transformer
anywho - don't mind my blabbering (or do lol advice is great )
here are pictures of the test fit!

^hastily arranged LEDs obviously I'll need to straighten them out and stuff but the tangle of cords was making things annoying at that point

you can see the shadow of the middle vertical support beam but besides that I don't think any hot spots are noticed that beg for diffusing

soooo I have this 98% finished
finally!
I have the wiring all done and staped up neatly and gave it a lil paint job also I applied heavy duty velcro on the face edges to be the way the canvas secures to the light chamber - I am probably going to have to use a small screw in the four corners though as the framing wood is a lil bit bowed and the edges not totally flat - but we shall see what is necessary.
I modified the canvas by taking out the shadow making vertical support beam but there are still two supports running the other way. Also I put little L brackets in the corners for some insurance (and finally the corresponding velcro tape on the face edges.
I am waiting on my heavy duty aluminum mounting brackets to come in the mail so I can hang this on a wall - so until then I haven't put the painting on the chamber because of storage issues and also I want a second pair of hands to help get it on right the first time (hopefully)

ohhhh great work man!
I know what you mean, I was thinking about aiming them in a different way but after my first test I found that the simplest way worked pretty well for this so I went with it.
I really like your work there, did you just use a jig saw to make those scrolling cuts?
good stuff
