led solar cells

With all the advances of led lighting today most people don't know one of the best uses of leds.SOLAR CELLS. Yes thats right the led can be used as a solar cell.When enough leds are connected together they will produce useful power.Pictured is a short circuit diagram of a solar cell I have built.
Look at the pictures and you can get a working knowledge of how I put them together.The white board is 540 red led it will produce 1.25 volts @22 ma.The plex is 280 red leds it will produce 1.25 volts @ 10 ma.The purf board is 180 yellow keds it will produce 1.25 volts @20ma. The yellow seems to produce more current at the same voltage.I have tried other colors but the red, yellow and orange seems to be the best.You can also use the red,green,blue blinking led.They produce the most power at 1/2 volt.The blinking led cost much more but produce much more power.Remember as with using leds as light they are voltage sensitive ie: 1.2 volt leds will not work with 3.2 volt leds.
The solar cells in the pictures may not be as powerful as a silicon cell but the leds are nearly indestructible.If a storm blows them down just put them back up.A silicon cell can't take that kind of abuse.The led cell can be used with a booster converter to get the voltage needed to charge AA or AAA batteries or even 12 volt batteries.If enough cells are connected in series and parallel you can achieve higher voltage and current.
I think best of all about leds as solar cells is you get to build them yourself.You can add to your cells as money and time permits.Good luck and give them a try.

led grow lights

With vegetables increasing in price the way they are it might be worth wile to grow your own.I have included pictures of a grow light system that I have been using to grow leaf crops, tomatoes and the like.You can use them for starting new seedlings.The arrays are 12 volt dc. but also can be used on ac.This marvel of the modern world is finding more and more uses as days pass.I hope someone can find this a help to lower there food bill and at the same time grow some great tasting veggies.

a real drag

Earlier this month I wrote and made a request to a co. in shanghai china.The co. is a major manufacturer of leds. I will post the emails I sent and the reply that I also received concerning the leds that I requested.The reason I am placing this information on my site is so all can see the results a real customer can receive when making an honest effort to do business with this co.
As you can see I will not be doing any business with them.If they can't take my request with a little respect then how will they treat anyone else!!!!!!!!
Lesson learned:::: Don't stray from your reliable source just to find maybe a better deal.

something to ponder while you read

If the human animal can go to the Moon and back. Why can't he make a pair of pants that will stay up on me????????????
