    Box Led
In summary: Hah sorry to hear that, I was really looking forward to using the UV LEDs. I Guess I'll have to find something else to do with the project. Thanks for the input though.In summary, the author built a woofer box and wants to connect LED's to it. However, he's not happy with the low light output of the LED's and is considering alternatives. He thinks about how to power the LED's and concludes that a dimmer would be too much work.

So I built this really nice woofer box for my 6.5inch sub. All clear acrylic, and working on sealing and reinforcing the sides and back.
My question is this:
Given that I purchased a Dayton Audio 25W plate style woofer amplifier, is there any way I can hook this up so that I can plug a string of parallel connected LED's into it?
My plan is to shine the LED's in multiple directions (UV) from the backside of the speaker so they aren't shining in anyone's face, pointed at the sides of the box, with UV acrylic paint on the sides and back for a really sweet effect.
My ultimate goal is to make it so the LED's bump to the music, and if I could get a dimmer and it would be an easy setup, I would do this. However, going through several years of EE has taught me that nothing ever works as planned, so I'm prepared to get a phone charger and plug it into the power receptacle on the backside of the amp for constant LED power.

I'll go take pics and get model information so you guys aren't like wtf.
Thanks for the help btw, this project has been really fun it's going to look bomb when it's done.

Sweet...
In years gone by, there was a craze for lights that flashed to the music. Those used a group of bandpass filters, about four or five, and level-threshold detector circuits for each. (think LM339 comparator)
Anyway, most of these were not very good as they either failed to react, because the volume was too low, or simply went on all the time, when the volume was too high.

Now's a good time to ask yourself some questions:
Do you want multiple effects for multiple frequencies?
Do you want patterns or sequences?
Do you want the lights to flutter brighter and softer with the bass, or flash on the beat?
Are you happy with they sensitivity issue (must be a certain volume range), or would you like it to work the same at high and low levels?

Think through these questions, and perhaps I can toss together a starting circuit for you to bread board ;)

Hah you know after reading your input, and thinking about it a bit more, I think this would be too much work for just UV LED's. I mean, if I was going to use blue or green ones with high mcd outputs it would be phenomenal, but I really want to stick to the UV paint and a rocker switch for on/off, maybe even a dimmer switch as well. I think the lack of reliability in the circuits combined with the low light output of the UV LED's isn't worth it.

But something is still picking my brain a little. With dimmers specifically made for LED's, does the decrease in voltage react on a logarithmic scale when it approaches the voltage cutoff? Because I've seen some LED circuits that can go way dimmer than I could ever achieve in lab because the cutoff is so sensitive.

Anyway, thanks for the info, I'll post some pics when it's done. Gotta get on my art buddy's *** to make me a sweet design that I can reproduce with acrylic paint.

Yes, the Led's can cover a very broad range by controlling their current. From one batch to another, they tend to vary in output and this is most notable when they are dim, even though the output is supposed to be in proportion to current.
There's a number of "switching regulators" to vary their dimness, but if you have power to spare banging a woofer, then you have access to enough power to simply regulated the LEDs with constant current or switch them with a simple ballast resistor in series.

If you have visions of UV driven art, I'd ignore issues with the UV diodes and just go for it. You can always drive them more gently, heat sink them better, or just replace them to make up for life issues. Art is art. If you have to throw the rest out the window to get at what's driving you, then go for it.

FAQ: Upgrade Your Woofer Box: How to Add LED Lights for a Unique Musical Experience

1. How do LED lights enhance the musical experience?

LED lights can enhance the musical experience by adding visual effects that sync with the beat of the music. This creates a more immersive and dynamic atmosphere, making the listening experience more enjoyable.

2. What materials do I need to add LED lights to my woofer box?

To add LED lights to your woofer box, you will need LED strip lights, a power supply, a remote control, and some basic tools such as a screwdriver and wire cutters. You may also need additional materials such as adhesive tape or wire connectors depending on your specific set-up.

3. Can LED lights damage my woofer box or affect the sound quality?

No, LED lights should not damage your woofer box or affect the sound quality if installed correctly. It is important to follow the manufacturer's instructions and use appropriate materials to ensure that the LED lights do not interfere with the function of your woofer box.

4. Are there any safety precautions I should take when adding LED lights to my woofer box?

Yes, it is important to follow safety precautions when working with LED lights. Make sure to use a power supply that is appropriate for the voltage of your LED lights and do not exceed the recommended wattage. Also, be careful when handling any electrical components and always disconnect the power supply before making any adjustments or modifications.

5. Can I customize the LED light patterns and colors?

Yes, most LED strip lights come with a remote control that allows you to customize the light patterns and colors. You can choose from a variety of colors and effects such as flashing, fading, or pulsing to create your own unique visual experience.
