A bulb-shaped modern retrofit LED lamp with the aluminum heat sink, a light diffusing dome, and E27 screw base, using a built-in power supply working on mains voltage. A light-emitting diode (LED) is a two-lead semiconductor light source. An LED is what's called a "solid-state lighting" technology, or SSL. Basically, instead of emitting light from a vacuum (as in an incandescent bulb) or a gas (as in a CFL), an SSL emits light from a piece of solid matter. In the case of a traditional LED, that piece of matter is a semiconductor. A wide range of gases is used in the LED manufacturing process. Argon is a commonly used gas used to fill incandescent light bulbs. It increases bulb life by preventing the tungsten filaments from deteriorating too quickly. Other gases such as helium, neon, nitrogen and krypton are also used in lighting. The gases used in light bulbs are known as inert gases. Location Head Off...
