I am About Change My Lamp
More than 150 years ago, inventors began working on a bright idea that would have a dramatic impact on how we use energy in our homes and offices. This invention changed the way we design buildings, increased the length of the average workday and jumpstarted new businesses. It also led to new energy breakthroughs from power plants and electric transmission lines to home appliances and electric motors. Like all great inventions, the light bulb, called incandescent bulb, can't be credited to one inventor. It was a series of small improvements on the ideas of previous inventors that have led to the light bulbs which we use in our homes. The light bulb was a great idea, but researchers have never found a way to increase its efficiency more than 10% and began to focus on other lighting solutions.
In early 1900s, they discovered another method to produce light that was totally different than the light bulb. They could produce light by removing almost all of the air from a long glass tube and passing an electrical current through it, an invention that became known as the Geissler tube. This was a kind of discharge lamp and was called fluorescent lamp. When the oil crisis came up in 1973, scientists had to develop efficiency of the fluorescent lamp for residential applications due to energy shortage that we still use in our homes.
While the fluorescent lamps were on the market as a lighting device, the light emitting diode (LED) began appearing as indicator lights and calculator displays in the 1970s. The invention of the blue diode in the 1990s quickly led to the discovery of white LEDs. To make LEDs an option...
