A light emitting diode (LED) is a semiconductor light source that emits light when current flows through it. The invention of the LED dates back to 1927. Russian inventor Oleg Losev created the first LED, but without any industrial or commercial application. Around the mid-1970s, it took decades for the first LEDs to be put into commercial use. of the last century. Since then, the LED industry and technology have developed further, with the demonstration of an experimental white LED in 2014. High efficiency and high quality, combined with low production cost and final price, bring LEDs into every home.
An LED light, or LED light bulb, is a type of electric light that uses light-emitting diodes (LEDs) to produce light. Unlike regular incandescent, fluorescent (and CFL), and halogen bulbs (which do require the use of some additional technology), which only require current to pass through and produce light, LED bulbs and lamps require an electronic LED driver circuit from the power cord operate. The LED chips require controlled direct current (DC) power, and appropriate circuitry as the LED driver converts the alternating current from the power supply to the regulated direct current used by the LEDs. So even though they don’t look like regular light bulbs, the technology behind LEDs does require more than electricity and wires…
However, LEDs are known for their long life, high energy efficiency and low maintenance costs. LED lights can run for 50,000 to 100,000 hours, or about 5 to 10 years. It is more energy efficient than incandescent bulbs because it wastes less energy by producing a small amount of heat. You can set it however you want, but in the end, LED bulbs consume 75% less energy and last more than twice as long as incandescent bulbs. The average American home has about 40 light bulbs, and if they were incandescent, replacing all of them with LEDs could save $300 a year in energy costs. That would be enough to make up the price difference in a year.
