What is LED
LED stands for Light-Emitting-Diode, and it's technology that has been around for a while. What differentiates an LED from a regular diode is basically that in the regular lighting that most people use, when current flows through, energy is released in the form of heat. In a light emitting diode, an electric
current passing through and causes light in the visible portion of the electromagnetic spectrum to be released. LED lighting technology in he past used to be created using semiconductor material such as gallium arsenide and were limited to only a few colors (mainly blue or green). Newer LEDs are made from synthetic materials such as Polyphenylenevinylene and can produce light of any color. LED-based lighting bulbs consume little current and last for over 100,000 hours, that's 30 to 40 years without dying out. LEDs can emit Infrared and Ultraviolet light. LED is incandescent and fluorescent lighting that are already replacing light bulbs in Europe, and soon to be mandatory in the United States as well. LED lights use 1/3 of the power that regular lights do. I'm sure every house owner would love to save money on electricity bills by switching to the more efficient, LED light. because Light-Emitting-Diodes save so much energy, and don't rely on heat, they go as far as helping the environment go green by helping decrease global warming. Nowadays, LED lighting technology have become a popular demand in today's market. By now you may have already replaced your old TV without a new, LED-Based flat panel television. Heck, some of you are probably ready this through your new LED lighted computer screen!
