dimming any LED


I don't know why I haven't thought of this before, but last night laying in bed I was thinking about my newly finished basement. I'm an electrician by trade and I wired up my basement with LED can lights (recessed lights) to a wall dimming switch. Now why can't someone wire up a LED dimming switch to say an outlet, then plug the LED aquarium light into that outlet? I'm thinking it would work just like my can lights. Now not all dimmers are rated for LED so you would have to make sure you got the right one. Let me know what you guys think of this. I wish I still had my exoconic to test this with, but as things go I just sold it and mailed it off friday.

It isn't likely to work as a dimmer for a LED light. LED's use a driver circuit which outputs a constant current at the right voltage, and it does this for a range of input voltages. To dim a LED you reduce the current. I suspect the dimmer you are thinking about would just make the LED driver work harder.

My can lights "ARE" LED's and my dimmer works. Each can light has it's own driver. I don't see how it wouldn't work. Thats why I said that you would have to use a LED dimmer, because those are current limiting not like your normal light dimming switch which is voltage limiting.

To dim LED lights you need a simple circuit made out of a 555 IC and a few components. This sums up to 10$ at most. If your dimmer costs less then it would make a better choice I guess.

Of course, not anybody has the tools to solder components but I think a cell phone repair guy can help with that for an additional 5$

I was just looking at the dimmer specks for my dimmer. As long as the driver for the LED is higher than 10V. As it says it doesn't work for 0-10V drivers.

Danielt, I'm not for sure exactly what you are talking about. But for a simple solution you can go to Home Depot and buy a $30 LED dimmer and a $1 outlet. Maybe about $5 for parts like a electrical box and what not, depending on how you want it to look. You'll have a dimmer you can adjust.

I'm tempting to try it on my new fugeray. I still need to go through the paperwork to see if I can find out what driver they use.

I'm talking about this simple circuit which costs about 10$ in parts.

That's just an example of how it can be done. The transistor converts amps to heat and takes the bulk of the payload and the IC generates the PWM signal that commands the transistor. There's also a potentiometer in there to modify the duty-cycle (dim) to your liking
