百年灯泡

悬挂于利弗莫尔市消防站的百年灯泡

百年灯泡(英语:Centennial Light)是全世界最长寿的电灯泡,且至今仍在持续运作中。它位在美国加利福尼亚州利弗莫尔市东大道4550号,由利弗莫尔-普莱森消防局英语Livermore-Pleasanton Fire Department负责维护[1]。这颗灯泡自从1901年装设完成后就一直发亮,迄今已亮了123年,而且很少被关掉过。百年灯泡以其超长寿命创下了健力士世界纪录[2],并为《李普利的信不信由你英语Ripley's Believe It or Not!》和通用电气等媒体所报导[3],也被视为现代电灯泡工业采行“计划报废”的证据。[4]

历史

百年灯泡是手工吹制而成的30或60瓦特灯泡(目前亮度相当于4瓦特夜灯)[4][5][6],采用灯丝,1890年代后期由谢尔比电气公司(Shelby Electric Company)于美国俄亥俄州谢尔比英语Shelby, Ohio生产制造[5];许多有相似生产背景的电灯泡,至今亦仍保存良好、可正常使用[7]。据席尔法·柏纳尔·贝克表示,“百年灯泡”的历史可追溯至1901年,由她的父亲丹尼斯·柏纳尔赠予利弗莫尔消防站[5]。柏纳尔原是利弗莫尔电力与水力公司的负责人;他在卖掉公司时把灯泡捐献给消防局。这段故事也由当代的消防员传为佳话[8]

1972年,该灯泡因记者迈克·邓斯坦(Mike Dunstan)的一篇报道而广为人知,吉尼斯世界纪录通用电气此后不久便确认这是世界上最长寿的电灯泡。灯泡在那之后只有两次较长时间的熄灭:第一次是在1976年消防站搬迁时,当时灯泡被小心地保存在特制的盒子里,由整辆消防车运载至新址,期间只熄灭了22分钟;在那之后,该灯泡被接入不间断电源,直到2013年5月20日因电源系统故障再次熄灭9小时45分,但灯泡本身并无损坏,在那之后又可被点亮。
