不同类型的电灯是怎么样工作的?李佳同学通过《电工手册》对不同类型的灯进行了比较,如下表.其中,效率是电灯把电能转化为光能的一种量度,所有电灯产生的内能都比光能多,但是一些电灯的效率比另一些的高;而寿命表示这种灯泡平均使用多长时间.普通钨丝灯,为了得到适当的电阻,钨丝要比人的头发还细并有lm多长.为了使它放人灯泡里,被做成“螺旋形线圈”.同时为了防止灯丝氧化和升华,玻璃泡里充有不易反应的惰性气体氟和氮.钨丝灯泡效率低且寿命短,但很便宜,它可以直接从电源得到电,不需要额外的设备.
灯的类型 | 效率 | 寿命/h |
普通钨丝灯 | 3% | 1000 |
荧光灯管 | 25% | 5000 |
(2)现在一种普通的钨丝灯泡,额定功率是60W,按正常工作计算,这种灯泡在寿命期内消耗的电能是______KW•h.
(3)60W的普通钨丝灯泡,使用时与功率是多少W的荧光灯管发出的光的亮度相当?
