The Replacements For The Incandescent Bulbs

In the recent trade show, there are some incandesent bulb's replacement appearing on the show, and according to the news, they are most likely going on the market next year.

                   
The incandescent bulbs is  be on the market for century, the idea about it is to turn electricity into heart, it consumes large amount electricity and so not efficency. So the US like to ban it, and introduce a new standard for the light bulb for the energy efficiency.

However, creat a replacement is also not a easy thing, people have to figure out how to fir new bulbs into lamps and ceiling fixtures designed for the older one.

Compact fluorescents are the most obvious replacement,it contains a small amount of toxic mercury vapor, which is released if they break or are improperly thrown away. They last longer than traditional bulbs but not as long as LEDs. Brighter models are bulky and may not fit in existing fixtures.

Organic light-emitting diodes, or OLEDs, has had problems reaching mass production.  They're used as vibrant color screens for smartphones. But making OLEDs that are big, bright, cheap and long-lasting enough for use as light sources has proved difficult, and it is using chemicals that are sensitive to oxygen and spoil unless sealed very carefully.

LEDs are efficient, durable and produced in great quantities, but they're still expensive. An LED bulb can contain a dozen light-emitting diodes, or tiny semiconductor chips, which cost about $1 each. The big problem with LEDs is that although they don't produce as much heat as incandescent bulbs, the heat they do create shortens the lifespan and reduces the efficiency of the chips. The brighter the bulb, the bigger the problem is.
