It has a flashlight, an LED flashlight.

The one thing we need to do is we have to replace these inefficient incandescent light bulbs, florescent lights, with this new technology of LED, LED light bulbs.

And this fiber turns a wire attached to an LED.

And you can see, this LED is going to glow.

I don't mention the high energy efficiency of these LED light bulbs.

Right, the current wants to run through the play dough, not through that LED.

Cars have LED based headlights, LED based back lights, and cars can communicate with each other and prevent accidents in the way that they exchange information.

We fit in an LED light bulb, worth three U.S. dollars, put in our signal processing technology.

Blue light is very efficient, so we have these tunable 24 bit LED lighting fixtures.

The problem is though that I wanted to explain to you how this really works but I can have four of these on my finger, so you would not to be able to really see them.

So, right next to my bed I keep a notebook, a journal, with a special pen that has a light on it, LED light, because I don't want to turn on the light and wake up my wife.

Capacity We have 10,000 times more spectrum, 10,000 times more LEDs installed already in the infrastructure there.

Now we have LED, but here you see the latest one, and you see how incredibly small it is.

These are LED lights that help the roughly billion people out there, for whom nightfall means darkness, to have a new means of operating.

And what we're seeing is that R D I Y has moved beyond just window farms and LEDs into solar panels and aquaponic systems.

They created for me the biggest LED in the world especially for TEDx in Amsterdam.

The books also have high packed LEDs on the spines. So it's all display.

In a zippy demo at TED U, AnnMarie Thomas shows how two different kinds of homemade play dough can be used to demonstrate electrical properties by lighting up LEDs, spinning motors, and turning little kids into circuit designers.

You all know remote controls have an infrared LED basically you switch on the LED, and if it's off, you switch it off.

This is one in my neighborhood. And they are much better better than traffic lights, better than four way stop signs.

Let me show you these slides here.

Show and move a spotlight on the desktop

He put up a slide a little bit like this.

This can be combined with LED lighting as well.

Now, every LED that is made these days gives blue light.

Every presentation needs this slide in it.

Go to the next slide in the slide show.

An LED is a semiconductor. It's an electronic device.

Go back to the previous slide in the slide show.

And hopefully this slide is going to morph beautifully. There we are.

The Title is used for both the name of the index file, and as a text label on the title slide. Note that this title does not affect the titles on any of the normal presentation slides the title slide is visible using the Sony projector setup prior to starting the actual presentation display.

And window farmers in Finland have been customizing their window farms for the dark days of the Finnish winters by outfitting them with LED grow lights that they're now making open source and part of the project.

Go directly to the first slide in the slide show.

What if every light bulb in the world could also transmit data? At TEDGlobal, Harald Haas demonstrates, for the first time, a device that could do exactly that. By flickering the light from a single LED, a change too quick for the human eye to detect, he can transmit far more data than a cellular tower and do it in a way that's more efficient, secure and widespread.

And I throw this slide in this is me, actually, two months ago and I throw this slide in because here is my favorite animal, chambered nautilus.

Go immediately to the final slide in the slide show.

This boot strap approach is based on the use of photovoltaics a simple, universal, and scalable technology that is easy to maintain. Typically, in the first stage of this process, consumers would use a renewable energy source such as LED lighting, selling any surplus until they save enough money to buy lamp oil (on which Africans spend around 20 billion annually).

And for that reason, we cover the LED with a phosphor cap.

And it was really her strength, I believe, that became the kind of mudra and imprimatur that has been a guiding light in my life.

Create and edit presentations for slideshows, meeting and Web pages by using Impress.

You can set up the properties for the entire slide show here, including whether to show the duration on screen, which of the slides in a presentation to include, and several other global settings.

I'm not going to go into any gucky slaughter slides.

I began to make LED sculptures that would live inside little boxes out of MDF.

It was to be hoped that Tokelau would become a beacon for other Territories and administering Powers.

You can see it in this case that's lighting this LED.
