Light Emitting Diodes (LEDs), “semiconductors that emit light when zapped with [positive polarity] electricity,”[1] are stolpskyltar on the verge of taking over the commercial and consumer sectors of the lighting industry. With företagsskyltar greater efficiency, longer useful lives, and their “clean” nature, LEDs are the future of led skyltar light, pushing traditional incandescent and fluorescent bulbs toward extinction. Only fasadskylt belysning the higher production costs for LEDs has extended the existence of traditional bulbs.
When viewing the history of traditional butik skyltar bulbs, the higher costs associated with producing LEDs is not an insurmountable neonskyltar hurdle to overcome. The incandescent bulb lingered for about 70 years before supplanting “candles, oil lanterns, and gas lamps” as the main source of lighting.[2] When the first crude incandescent bulb was reklam created in 1809 by Humphrey Davy, an English chemist, using two charcoal strips to produce light, it remained impractical. Later when the first true incandescent fasadskylt bulb was created by Warren De la Rue reklam skylt in 1820, utilizing a platinum filament to produce light, it was too expensive for commercial use. Only when Thomas Edison created an incandescent bulb jusskyltar utilizing a carbonized filament within ljusskyltar led a vacuum in 1879, did the incandescent bulb become practical and affordable for consumer use.
