how to connect 8+ 1watt leds with ability to dim, select groups or single bulbs with possibly a renote control. Any ideas? Im not an electrician so please b clear.

Hello Amped313,

Just to be clear what are the LEDs, e.g. part number or spec, 230V ~,12Vdc?

regards

Hey Boss,

I havent got that far yet. I guess I will have to look into it in more depth. Im designing a sculpture and it basically a lamp , controlled at the base and each 1W Led (luxeon or something cooler) will spider out from the center kinda like a tree I guess and the bulbs would the rogh equivalent of  leaves to simplify it. I would like to be able to controll (Lets say in a 10-20 bulb config) dimming and also be able toturn on 3 or 5 or 8 at diff times or if possible blink.  (if that clears it up at all). Is there a control module I can wire into the base that wouldnt be gaugy and knob or switch controlled easily be an end user?

Thanks for reaching out.....Ed

Hi amped313

It becomes a more sophisticated matter! Maybe something like a small light modulator, as used by Disk-Jockey’s? But the low power of each bulb (or LED) remains a technical barrier.

Kind regards,

Hi amped!

To dim your LED bulbs, a standard dimmer is not suitable, due to the very low power consumption. I suggest the use of 2.2 Mohms anti-log potentiometers inserted in series with one wire of each bulb (connection between left-hand side tap and centre tap, viewed from the axis side). Buy an (isolated) box to install all your potentiometers, and complete your design with mini-switches inserted in series, too, to control your bulbs on or off; as far as I know, it's the only -cheap- way to build a remote control. Due to the low power consumption, again, these mini-switches have just to withstand your line voltage, don't worry about the current.

To explain this in the most simplest way: connect one wire of the line to one tap of the switch; connect the second tap of the switch to the left-hand side tap of the potentiometer; connect the centre tap of the potentiometer to one tap of the bulb; and finally, to complete the loop, connect the second tap of the bulb to the second wire of the line.

Kind regards,

B.B.

P.S. : Wired as described, the light intensities will decrease as the potentiometers as turned clockwise. To invert their behavoiur, simply connect the right-hand side tap instead of the left-hand's one.
