"... as we KNOW diode act as a switch" - Go back and check that statement in the literature.

THATS WHAT VIJAY IS ASKING. CAN WE USE IT IN OUR HOME AS SWITCHES?

I think he (and possibly you) have heard the term "switching diode", and taken it to mean that a diode could, in some magical way, be used as an on-off switch.

You can do what you like in your home, as long as your SHOUTING doesn't disturb your NEIGHBOURS!

i think it will not work because there is cutin voltage for every diode.

What do you mean? There are diodes that are rated for thousands of Volts PIV at various amperages.

What are you trying to do?

u got the correct answer i think.

Has anybody tried a diode in lighting circuit for an incandescent lamp?. As it flickers 50 times in a second,will the flicker be visible to the eye?.

I replaced the coins in my lamp sockets with these:

No more blown fuses or tripped circuit breakers!

No, but I bet it will be visible even in our 60Hz system here, to some eyes. My wife is very sensitive to the flicker in a dimmable LED, even with a good dimmer made for LED bulbs. She still picks up that minor ripple, which is nothing compared to what a diode would do.

On a similar subject, eyes, is the dress blue and black or white and gold?

Yes until the bulb burns out and then goes permanently dark. Incandescent lamps don't like being operated this way.

The flicker rate will slow down to 25 times per second and most people can see the affect especially at night.

One of our managers in the recent past did not like the color of light and the flicker from his new lighting in his new office so he launched a "trial-and-error" experiment of adding resistors, diodes, and capacitors in many different configurations to incandescent and fluorescent light fixtures over a period of 2-1/2 months until he was satisfied.

The technicians and I learned a lot about what not to do and we were very frustrated as despite management mandated project deadlines, their "real" work was stalled.

I estimated the cost of the experiment verses buying new LED lighting in the proper color spectrum for his office to be about $11 to $1.

What a waste of manpower but who am I to blow against the wind?

There are more that one kind of switch.

DIODE = SWITCH?

1. yes.

2. no.

DIODE = SWITCH?

1. yes.

2. No.

Diode = Diode.

Don't they use a double lickover bridged diode charging henweigh circuit in Turboencabulators?

Or, is that flux capacitors?

that's the single lickover

don't confuse things

I think it is flux capacitors with double licker-over & over ambiguous induced affect which was discovered by Ben Dover back in 1968.

It was 1967.

Lordy!

LOL!

They say; "If you can remember the 60's, you weren't there."

Funny; I remember the 60's because I was "there", but the dates, names, and details for some reason are getting foggy as time marches on.

Some of it might be intentional to protect the names of the innocent.

Oh well, nothing some Annie Green Springs, Very Berry, or a good, cold beer and good company wouldn't cure.

I consider myself living proof that recovery is possible. The style may have changed, but the substance of most of the issues then remains today. The overwhelming consensus that the technology that allows us to communicate like this should resolve into the free and fair is particulary heartening.

Yes! I see great strides in knowledge sharing taking place throughout the world and my hope is that the greedy, selfish, and short-sighted politicos do not tax the system into limited or no functionality.

Currently the opportunities are boundless for all regardless of monetary standing which in turn allows a far greater wealth of knowledge to be "tapped" for all of our benefit.

If we can keep it free who knows the limit of what we will be able to accomplish and see.

Right on, man!

LOL!!!!! Nice one door man!

Diode? Nope. BJTs yes- but same pinciples as diodes are made. NPN, PNP (Emitter, Collector, base)

But, process is not direct could one to 2 steps and cost unwise. Why not settle with simplicity and practicality? Use tumbler or ordinary switches available.

It won't work.

Because diodes don't work that way with AC. Even on DC the relationship is far more complex than a simple air break switch.

http://en.wikipedia.org/wiki/Diode

Heck, I have a manual somewhere just on diode theory, operation and application that is a few hundred pages long. Such is the nature of electronics, nothing is ever as simple as it first appears.

Nonsense. A diode is the electronic version of a one-way-street. A non-retun valve. A ratchet. None of these works in the same way a switch does, Mildred.

Did you study electronics in some way? I hope you got a refund of the course fees!

There are electronic devices related to diodes... Silicon Controlled Rectifiers (and TRIACs), which instead of having a single PN junction, have a double PN junction (PNPN). These are 3 terminal devices that act like diodes after being "turned on" by applying a voltage at the third terminal (the gate). And back to your question, these are used in lamp dimmer circuits.

http://en.wikipedia.org/wiki/Silicon-controlled_rectifier

Whilst they don't act as switches, diodes can improve the versatility of switches in the home, for instance diodes can be employed to enable one wire to control 2 separate circuits, they do this essentially by (in your words) withdrawing 230 volts. This is especially useful where the installation of extra wiring is problematic.

Does your instructor/professor know your using CR4 to complete your home assignments??

"Does your instructor/professor know your using CR4 to complete your home assignments??"

Does YOUR instructor know that YOU're one of those cr4 flunkies who doesn't know the difference between:

a) your & you're

b) there , their , and they're

c) two , to , and too

d) mute and moot

e) etcetera ("etc") and ekcetera

f) etc., etc., etc.

Go back to kiddiegarten, and grow up knowing the language that you ("so-called") claim to speak...(!)

["Over and out."]

Does your mother know you're using her computer?

Grow up!

You have developed a pattern that is childish and moronic.

Go away.

It's an AP, not worth time or effort.

A diode is a two wire device that does not work as a switch, it merely stops currrent flow in one direction. To make it into a switch you need to add a third wire to the base of the diode and to differentiate it from a normal diode we call a three wire diode a triode or a transistor. Applying or removing a voltage to the third wire turns this new sophisticated diode (transistor) on and off. Unfortunately you need a switch to apply the voltage to the base of the transistor. i.e. to make it work you need both a transistor and a switch. So why bother. Diodes and transistors only work on DC current and 230 volt domestic supplies are AC. To get arround this problem we make the transistor even more complicated and to to differentiate it from a transistor we now call it a bidirectional triode or a thyristor. Thyristors are used in domestic lighting circuits. Look up dimmer switches for domestic lights and compare the price with the price of a normal light switch.

I think I have a design that, with a little tweaking, may work. It involves two diodes in series with anodes connected and cathodes facing out or vice versa, +/- -/+ or -/+ +/-. This provides the OFF state.

To achieve the ON state, physically rotate the diode pair out of the circuit and rotate a conductor, say a piece of wire, into the circuit.

Is this enough info for me to get a patent?

No. Too simple. Use a stepper motor and control circuit to rotate the device and a solar cell to actuate it.

Or go to Lowe's and get a Leviton wall switch.

It would have been enough info but you have told us about it so it is now in the public domain and therefore not patentable. For a patent to be granted you also have to make a claim as to why it is an improvement on current equipment. Your claim maybe that it sells lots of diodes so boosts the economy (and your shares in the diode manufacturer)

It is also a Green initiative. I just realized we can recycle all diodes that have failed open into this diode switch, thus reducing the waste stream and also reducing the environmental impact of producing the materials needed to make more diodes.

The Doctor Frank N Stein diode knife switch can be used to bring various assorted body parts back to life.

Its Alive!

He posts! My monster posts!

I suppose you could call the switch on a minnow bucket aerator a "Bait-n-Switch".

OMG. Don't quit your day job.
