的 立法局 請閱讀下列敘述後,回答24~25題 講到節能省電,大部分人多會選購省電燈泡、LED 燈泡這兩種燈泡。省電燈 泡尺寸與傳統燈泡(白熾燈泡)相近,但較省電且使用壽命更長;而LED燈泡 相對用電更少,使用壽命最長,用途也較廣,但價格較其他燈泡高。明欽將 家裡的傳統燈泡(白熾燈泡)與省電燈泡、LED燈泡做比較,後製如表(一): 表(一) 傳統燈泡 省電燈泡 LED 燈泡 一護封面 可取 燈泡類型 (白熾燈泡) 瓦數(W) 流明(Im) 60 24 720 14 1440 1260 使用壽命(小時) 1000 6000 25000 ★瓦數(W):瓦數是耗電量的單位,數字愈小表示燈泡愈省電 ★流明(lm):流明是光通量的單位,數字愈大表示燈泡愈亮 AD24. 發光效率代表光源將所消耗之電能轉換成光的效率,以光通量與耗電量的 比值來表示,其單位為 lm/W。今明欽欲將家裡的傳統燈泡換成省電燈泡, 若他所選購的省電燈泡其流明數與家裡的傳統燈泡相同,且發光效率與家 裡的省電燈泡也相同,則他所選購的省電燈泡瓦數為何?

(C) 14W (D) 15W 25. 已知「1度電」指的是耗電量1000瓦(W)的電器,連續使用1小時所消耗 的電量。設某年夏天1度電的電費為4元,且明欽家每年夏天每盞省電燈 泡與每盞 LED 燈泡皆使用1000小時,為了節省電費,明欽欲將家裡的一 些省電燈泡換成LED燈泡。若明欽家裡原有20盞省電燈泡和8盞LED燈 泡,則至少需要將幾盞省電燈泡換成LED燈泡,才能省下500元的電費?
