pc power supply to power 12 volt outdoor led lights?

We Answered:

First, PC are not 12v power supplies. Second, your power supply should have the capability to produce your required current power at no more than 80% of total supply capacity. A circuit will not draw more current then what it needs. LEDs are simply Light Emitting Diodes. Diodes forward bias is .6v generally. The wattage is the amount of heat dissipated (or light in this case) the diodes will generate. You want to know what the power requirements are for a 12vdc power supply to produce 4W. Remember, we are using 4W so that we do not approach the power supply's max output by more than 80%.

I = P/E Ohm's law ( I = current, P = watts, E = voltage )
I = 4w/12v
I = .33 amps

Now we solved for current requirements, you know that a 12 volt power supply that will supply a sufficient current of .5amps will be adequate and you meet the max capacity by 66%

Wire lenght should not be included in this calculation. Wire resistance is pratically nill.

Transformers are AC (alternating current) which uses volt-amperes (VA) as a power rating. These are step down transformers (usually from 120vac to 12 - 24vac with no bridge rectifier). This is not the currect application. If you use a plug in power supply that has a 12v output @ 1A, this will surfice. These are plentiful and can be obtain anywere.

How do you make a string of LED lights for an outdoor Christmas light display?

We Answered:

i agree with botoboto buying a string of pre-made christmas lights will be much easier, if you are interested in understanding electronics grab a introductory book and work your way up this will save you lots of money by avoiding big mistakes

Ruth Said:

I bought outdoor Christmas lights, LED colour changing lights, how do they change colour?

We Answered:

Yes there is a Green and Red Led inside "EACH" Bulb....

But did you notice there isn't a separate wire for Each bulb???
Here's how they make Different Colors.....

They flip the Positive and Negative polarity back and forth on the wire....That little box does the flipping....

So if one wire is positive....IT's Red.
Then that same wire is negative...It's Green..
If they split the time evenly then IT LOOKS YELLOW!

But they gotta flash it back and forth for yellow to appear...over 25 times a second minimum....otherwise you'll see flicker...

Faster makes flicker disappear.....That's the box's job (it's a microprocessor)

When you "Blink" at the lights....guess what....you're "capturing a short "slice" of color....that color can be Red.....or it can be Green....

If you do the eye-blink trick with a fan....the blades can seem to stop...

Discuss It!
