Plasma is a state of matter in the same way that solids, liquids and gases are also states of matter. Plasma is found in fluorescent light bulbs and is used to generate images in a plasma television. So, a television has the same kind of plasma as a light bulb but applied in different ways.
A light-emitting diode (LED) does not emit light by a mechanism involving the creation of plasma.
In the LED, we see that a semiconductor will, under certain conditions, emit photons when electrons combine with holes in the semiconductor material. The emission of photons (light) is what the investigator would expect as the device produces illumination. But the mechanism by which this happens does not involve plasma physics. It's a semiconducting phenomenon. Use the links below to discover how the LED works.
Anchor,Philips,Wipro,Havells are some of the led manufacturers
Sometimes it is but depends how hot the light gets.
The pixels of LCD TV is filled with liquid crystals and arrayed from backlight or reflector to produce images. Plasma TV has many tiny cells between two panels of glass that hold a mixture of noble gas. The gas is electrically charge turned into plasma which produces lights and images. Plasma uses power per square meter, the brighter the image the greater its consumption. LCD is very efficient and power saver.
Yes. Due to the fact that they are based on fluorescent (probably spelled that wrong) lighting. Fluorescent lighting uses large amounts of electricity to excite gaseous atoms into plasma, the fourth state of matter where electrons fly free from their nucleus, thus plasma tv's have plasma
LED (light emitting diode) is an electronic component that generates light from the electrons flowing in one direction through it, in an electron circuit, possibly as part of a circuit board. In a circuit the light emission can be a short as a nanosecond. One or more LED's can be used to make light with a minimum of electricity. Modern applications are wide spread including optical sensor activators, calculator displays and automotive tail lights. LED's have come down in price and can last for tens of thousands of hours so have become an economical replacement for other lights in some applications.
LCD are little lights for each and every pixel, while plasma has two pieces of glass with plasma between the two.
Plasma tvs are flat panel systems that are used in large televison displays. HD or "High definition" tvs have a higher resolution which results in clear image quality. LED tvs use LED lights for back lighting.
For PLASMA tv and lights
yes they are led lights

In general an LED consumes less energy than a Plasma.
Yes Plasma TV are more expensive then LED as you will get more features with Plasma TV
There are many popular types of LED (Light Emitting Diode) lights for the holiday season. This includes LED icicle lights, white wire LED lights and regular LED lights.
fluorescent lights
natural - lightening, the auroraman made - neon and florescent lights
plasma TVs and fuorescent lights.
Plasma TV's often have a wider viewing angle then LED tv's. LED's are often brighter and more vibrant. I would suggest a plasma for a wider and larger room. LED's for smaller rooms.
