Edge lighting question
Edge lighting question
I am designing a project and I would like to use edge lighting as part of it. The attached pic shows an example of my project. I want to use LED strip lighting around the perimeter of the glass.
I need the strip to be battery powered. The width of the wooden frame would be approximately 4". Can I get a battery pack small enough to fit inside the frame?
Any suggestions from members familiar with edge lighting will be appreciated.
Thanks in advance,
Phil

Re: Edge lighting question
To power an LED strip at full power you'll need 8 AA batteries.
The frame is 4" wide? How deep?

I can adjust the depth to accommodate. How thick is the battery pack?highpockets wrote:To power an LED strip at full power you'll need 8 AA batteries.

Phil,
With it being an oval, I don't think you're going to find a battery back to fit, you may have to cut a groove in the back of the frame and create your own pack.

Re: Edge lighting question
Look at the 12V I posted a link to on Amazon.
Trying to find out the amp hours of the battery.

Re: Edge lighting question
How long are you shooting for the batteries to last?
Looks like the single 12V should last about 24 hours with pretty good elimination.

I plan to cut a groove in the back. Is this what I would be considering? https://www.ledsupply.com/led-strips/ba ... hoEALw_wcBhighpockets wrote:Phil,

Re: Edge lighting question
Do you want just white are colors?
How big is the oval? Do you want to go all the way around it?
Do you want remote control or just a on/off switch? Actually if you want color just an on/off switch won't work.

Oval is 24"w x 32"h.
Remote would be nice.

OK, check out this link https://www.ebay.com/itm/LED-Strip-Ligh ... 440ca5e79c
Forget the little batteries from Amazon, too many LEDs it wouldn't last long at all. Take 8 AA batteries and solder them in series, put the in a groove on the back of the oval along with the wireless receiver.
Let me think about the 8 batteries for a bit, I think I have an idea to make it easy for anyone to change the 8 batteries....

Re: Edge lighting question
Current Draw
Because there are three LEDs in series, you cannot drive these LEDs from a 5V supply. The LED strips say "+12V" on them to mark the anode and that's the maximum voltage we suggest. We've found that if you're ok with them being a little dimmer, even 9VDC works very well.
Each segment of 3 LEDs draws approximately 20 milliAmperes from a 12V supply, per string of LEDs. So for each segment, there is a maximum 20mA draw from the red LEDs, 20mA draw from the green and 20mA from the blue. If you have the LED strip on full white (all LEDs lit) that would be 60mA per segment.
To find the total maximum current draw per meter, we would multiply 60mA x 10 (ten segments per meter for the 30/LED per meter strip) = 0.6 Amps per meter OR 60mA x 20 (twenty segments per meter for the 60/LED per meter strip) = 1.2 Amps per meter. Again, that's assuming you would have all the LEDs on at once and that you are powering it from 12V. If you're going to be PWM-fading between colors, maybe 1/2 of that is what you'll be drawing. Still, you do need to have a fairly decent power supply to run this strip, all those LEDs add up!

Re: Edge lighting question
Great information Gerry. Hadn't thought about the size of the oval. There would be something like two meters of LEDs to encircle the entire oval, depending on where they were placed. That's a lot of LEDs to power for any length of time on batteries.
However if you want to do it, it can be done, it's just a matter of how long the LEDs will be very bright...
One idea for using AA batteries would be to use individual AA battery holders placed in a groove around the oval and hook the batteries in series and hook them to the LED wireless receiver.
