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

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.

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

And, third, they put the refrigerated goods behind closed doors with LED lighting.

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

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

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.

Then it has detectors on its back so it can sense how much starlight or moonlight is hitting its back.

And this fiber turns a wire attached to an LED.

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

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.

This can be combined with LED lighting as well.

These are of those who rebel against the light. They don't know its ways, nor stay in its paths.

These are of those who rebel against the light. They don't know its ways, nor stay in its paths.

They are of those that rebel against the light they know not the ways thereof, nor abide in the paths thereof.

They are of those that rebel against the light they know not the ways thereof, nor abide in the paths thereof.

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

And this is really heavily backlit.

Extruded typography that's backlit with neon.

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

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

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.

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

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

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

The flashlight gives us this really intense, bright L.E.D., and six hours worth of rechargeable battery pack, and the lunch box is a nice little package in which you can put everything inside, and a bunch of mini speakers to sort of amplify the sound large enough.

Now, what we're doing is, we're doing one that will be both frontlit and backlit.

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.

Very simple boxes you just press one button and some LED interaction occurs.

This is Symphony Space on 90th Street and Broadway, and the type is interwoven into the stainless steel and backlit with fiber optics.

This wall of undisturbed snow, back lit by sunlight, shows the striations of winter and summer snow, layer upon layer.

But when it's backlit, it's color and when it's frontlit, it's black and white at three times the resolution.

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

Prof Czeisler recommended that students should consider setting an alarm for when to go to bed, as well as for when to wake, and be aware of the harmful effects of 'blue light' emitted by electronic screens and LED lighting, which can throw your circadian rhythm out of kilter, leading to problems falling asleep.

And it opens and closes the shutter so the amount of light coming out of the bottom which is made by the bacterium exactly matches how much light hits the squid's back, so the squid doesn't make a shadow.

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.

And one of the reasons you can't see it is because it's backlighting most of the time, most cell phones.

Behind the humor is the idea of making the cubicle more human.) David Kelley So here's the final thing, complete with orange lighting that follows the sun across that follows the tracks of the sun across the sky.

And you'll see that it leads with a shifting star field, and there's an Aurora Borealis in the background, kind of morphing with color. The color of the Aurora Borealis can be controlled using this single bar of color at the bottom, and we'll put it down here to red.

A residential solar power system consists of just three components the PV modules, a battery storage unit, and a charge controller. Such a system can supply low voltage DC electric power at five volts for mobile phones, and 12V for LED lighting, pumps for outdoor use, and electrical appliances such as computers and televisions.

In fact, in many of the statues, when you excavate them, the backs are totally smooth almost glass smooth.

They're littler computers, so the one chip computers, I began to program one chip computers and make objects out of P.C. boards, LEDs.
