Statistics and facts about LED lighting in the U.S.
by Isabel Wagner
A light-emitting diode is an electronic semiconductor
device which is used in digital displays and lamps. In general lighting, incandescent
light bulbs are still the most widely used electric lights today. However, many countries, including the United States, have begun to phase out incandescent lamps in favor of more energy-efficient light sources such as light-emitting diodes and organic light-emitting diodes. In 2019, LEDs are estimated to achieve a 53 percent penetration of the global lighting market.
As Asian countries are likely to increase their share in global sapphire production,
thus eroding the price of semiconductors, the cost
of LED lamps is expected to decrease rapidly.
Currently, LED lighting is predominantly used as a backlight technology
for television and mobile phone screens. In 2011, the North American LED market was sized
at around one billion euros.
