Fred,

Most will build a shallow box to mount the litho in and back light it with a low heat light. Most are using a puc light from Lowe's or HD.

This is the option that I use most of the time... keeps the cost down for the customer. makes my job easier and quicker, looks very modern and makes a great night light ... it lights the entire wall behind the litho..........

4 Alternate Option using LED's on Sat Oct 31, 2009 11:28 am

Hello All,

Here's my alternate method of lighting a lithopane using low voltage LED's
(L-1069 BA9S T10 BULBS SMD SMT 48 LED HID WHITE) these are used as replacement dome lights.

If you prefer a whiter back light this maybe an option to consider. I like the fact that it's low voltage & power consumption besides less heat build up in the light box.

Adding the plug & switch adds a little more to the cost of the project.

Here's a link to the photos of the LED lighting behind a 5" x 7" litho.

Thoughts, comments , even cheap shots are all welcome

Best
Ron

BTW: Next to test with a 80mm circular led pattern for more even light distribution

Ron,

The LEDs really light it up. The eagle shows up great.

Can you share your source for the lights, cost and a little more detail in the "how to".

I just placed an order for some acrylic so I am looking at doing a few lithos.

6 LED source and additional info on Sat Oct 31, 2009 5:27 pm

FWharris,

The led panel is a L-1069 BA9S T10 BULB with 48 smt LED's, size is roughy
2.5" x 1.5" which uses 9VDC - 12VDC . I sourced these off eBay which shipped from Hong Kong for $8.00 each with free shipping. I've seen these at the local auto stores but at nearly twice the price. So key search on ebay using "L-1069 BA9S T10 BULBS SMD SMT 48 LED" which will provide several hits.

Used a 9vdc 350ma transformer from Jameco (www.Jameco.com) part# 202155 $5.95, basically because that's what I had available in the parts bin. The 9vdc power supply offers the same luminescent as a 12 v supply

If you decide to provide a power plug on the the light box besure to match the size to the transformer plug which in this case is 2.1mm x 5.5mm also available from Jameco or the Rat Shack.

Also be sure to observe the polarity as you wire the switch and power plugs up as you could let the blue smoke out of the led panel.

The model LED panels I received all had 3M double side tape applied to the back. So far they appear to have adhered very well to the back wood panel.

If any one finds a US based source at a resonable price please advise the group.

Hope this helps

Best Ron

Ron,

Thanks for the information. This can really help with making the boxes shallower for the lithos. Less bulk and materials. I know the couple that I have built were fairly large and that could be an issue for finding a place to put it up.

I have been using the 12volt LED's that come on a reel with about 300 lights and can be cut to length in groups of 3. These seem to last a long time, don't produce heat and being 12VDC it is child safe, pet safe too.
Here is a link showing both types of LED's that I've used, I prefer the flat ones myself.

I get almost everything needed off eBay, LED's, switch (SPST), power supply, and power supply plugs.

Hope this can help some one out there. You can email me if you have any questions @ the carvewright forum or @ alexanderjerryd@yahoo.com
