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

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.

In coal mines, this canary was supposed to be close to the miners.

Article 10 The State shall maintain order in production and other work in coal mine areas and protect the facilities of coal mining enterprises.

And this fiber turns a wire attached to an LED.

If public utilities or other projects need to be constructed in a coal mine area, the unit concerned shall consult the coal mining enterprise and reach an agreement before it may start construction.

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

This can be combined with LED lighting as well.

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

(3) to disrupt the order of coal mining areas, so that coal production and other work cannot be carried on normally or

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.

In consequence, people are moving back into mining areas in numbers, miners are digging at will with no fear of interference from the authorities, and the level of mining activity has increased significantly over the past few months.

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

It has a flashlight, an LED flashlight.

And the coal companies just move on after the mountain was emptied, leaving even more unemployment in their wake.

All units and individuals shall be forbidden to disrupt the order of production and other work in coal mine areas.

prohibition of work in underground parts of the mines for women

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.

Play a puzzle game similar to Diamond Mine

Another one is that I met a miner. He was home on his three month leave from the mines.

That's the phrase which I learned from my son George, who is there in the audience.

Article 44 Coal mining enterprises must provide accidental injury insurance for miners working underground and pay premiums.

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

They both kept their day jobs. Here's the last mine.

Just ask the coal miners in Australia.

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

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

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

Countless lives have been saved by canaries in coalmines a simple and invaluable way for miners to know whether they're safe.

Although mining monitors have been deployed in the major diamond mining areas nationwide, their work is limited by a lack of transport and other logistical constraints.

During overflights, the Panel was able to identify two D6 Caterpillar earth movers, a sizeable mechanical digger, at least 60 miners at work, pumps and a washing plant.

The Panel noticed a general movement of people into mining areas in search of work.

CHAPTER V PROTECTION OF COAL MINING AREAS

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

The State shall take special protective measures for miners working in underground coal mines.

If you happen to want to hunt animals at night, you take a miner's lamp, which is a pit lamp.

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

(c) exploitation means the recovery for commercial purposes of polymetallic sulphides or cobalt crusts in the Area and the extraction of minerals therefrom, including the construction and operation of mining, processing and transportation systems, for the production and marketing of metals

Wolframite occurs with cassiterite.

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

Summary of gold, cassiterite and wolframite comptoirs approved by the Ministry of Mines
