1LED灯的发展困惑LED(light Emitting Diode,发光二极管)于上世纪60年代问世,开始仅应用于仪器指示光源。20世纪末,美国科学家发明了能发出白色光的LED。LED作为新型电光源,其生命力在21世纪得到爆发,由于LED灯具有发光效率高,耗电量少,使用寿命长,安全可靠性强,节能环保等优点,迅速被制作成一般照明灯、日光灯、射灯,广泛应用于住房、工厂、景观、交通指示等场所,并逐步扩大到所 1LED lamp development Puzzled LED (light Emitting Diode, light-emitting diode) in the 60s of the advent of the beginning, began to be used only instructed light source. At the end of the 20th century, American scientists invented the LED to emit white light. LED as a new type of electric light source, its vitality in the 21st century broke out, because of LED light with high luminous efficiency, low power consumption, long life, strong safety and reliability, energy saving and environmental protection, etc., was quickly made into a general lighting, fluorescent , Spotlights, widely used in housing, factories, landscapes, traffic signs and other places, and gradually expanded to
