Electrical question

Post by ed »

We put in a wall. Ironically constructed by Mexicans.

We want some lighting. Got some 12v little things. But we found another light. LED too but 120 volts. It seems to me that I can convert the sucker to 12v like all of it's brethren and like any good christian LED ought to be. Anyone want to venture thoughts on this matter?

Rob, I will not refrigerate it.

Ironic Mexicans?

Are you sure you don't mean "sarcastic"? :p

I doubt you'll have much success. From Wikipedia:
LEDs run on direct current (DC), whereas mains current is alternating current (AC) and usually at much higher voltage than the LED can accept. LED lamps can contain a circuit for converting the mains AC into DC at the correct voltage. These circuits contain rectifiers, capacitors, and may have other active electronic components, which may also permit the lamp to be dimmed. In an LED filament lamp, the driving circuit is simplified because many LED junctions in series have approximately the same operating voltage as the AC supply. LEDs require a power supply system (driver) to interface them with the electric network.

As I recall from my electrical engineering days, leds are back biased diodes. They somehow hold the voltage at the zeiner break point or something like that ... they limit the current so the damn thing don't burn up.

Thing is that they have a rectifier and transformer in the 120v light. Seems I can hack that stuff out and go directly to the current limiting circuitry.

Hmmmmm I sense trial and error brewing.

Dude! Are you on drugs or something? You might as well say, "Hey, I've got this random box of electrical shit that I need to connect somewhere. How do I do that?"

What kind of reply do you want? You gotta be more fucking specific. Otherwise:

Hey ed, just buy some random LVPS along with some random wires and fixtures and that will be it.

Now pay me.

Hmmm ... plugged in the fixture in question. Too damn bright. Needs to be returned.

When you return it make sure they understand the light is too bright.

We don't want them to inadvertently put that back on the shelf.
