Show the seconds LEDs

It has a flashlight, an LED flashlight.

And this fiber turns a wire attached to an LED.

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 you can see, this LED is going to glow.

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

Check this if you want to see the inactive LEDs.

Check this if you want to display seconds LEDs in order to see the seconds.

Check this if you want to see a grid around leds.

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.

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.

All those red lights. Everywhere, there was a red light.

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.

The United Nations is their beacon of hope it is their light.

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

It was dark and there were no streetlights.

Well, it was dark and there were no streetlights.

Active LEDs

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

Inactive LEDs

Road design makes a difference, particularly intersections, of which there are two types signalized and unsignalized, which means stop signs.

Three times we were lost, and each time he led us back to the trail.

When you leave the highway, turn off all your lights.

Show the inactive LEDs

I think this lamp has a short because the light comes on only if I jiggle the cord.

Wait for the light to stop the traffic.

LED lights is really a revolution in lighting they're super efficient and you can design lights in a new way.

I got a good look at him under the lamppost.

The light at the intersection goes red. Traffic stops.

The illumination came from an electric light bulb in an adjacent room and from a street light which was positioned some 60 or 70 feet from the house but partially obscured by fruit trees in the yard between the light and the house.

Go straight down the road, and when you pass the traffic light you're there.

Bishop's Rock to Ambrose Light without a stop.

This can be combined with LED lighting as well.

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

And then you have these millions of street lamps deployed around the world.

And every street lamp could be a free access point.

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.

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

Use custom color for active LEDs
