Abstract

本实用新型系一种半波供电的低功率楼道灯,包括整流二极管及220伏普通白炽灯泡,其特征在于:二极管实现半波整流,白炽灯泡由整流后的半波电源供电,二极管与灯泡串联接入市电电源。220伏白炽灯泡由半波供电后,其功率降为原来的一半。这样,可以很方便的制成低功率的照明灯,供楼道照明使用。

Description

半波供电低功率楼道灯
本实用新型涉及一种低功率、可通宵长明的楼道照明灯。
在日常生活中,人们希望楼道设有夜间长明灯,又希望将这种长明灯的功耗降至最低,因为这种灯的亮度并不需太大。目前直接以市电220伏为电源的白炽灯泡,最低功率是15瓦(由于技术上的原因,低于15瓦的220伏白炽灯泡很难制造),若将其作为楼道长明灯,仍显功率过大。
本实用新型的目的在于:克服现有技术之不足,提供一种造价低、半波供电、功率小于10瓦的楼道照明灯。
本实用新型是这样实现的:低功率楼道灯,包括整流二极管及普通220伏白炽灯泡。其特征在于:整流二极管实现半波整流,白炽灯泡由整流后的半波电源供电,二极管与灯泡串联接入交流220伏电源中。
本实用新型的特点是:
1.利用二极管的单向导电性,对交流220伏电源实现半波整流,根据电路理论可知,整流以后的半波电压的有效值是全波的

伏,降低了30%左右;同样半波电流也为全波的 也降低了30%左右。两者相乘,即为功率,功率则降至原来的1/2。利用这种办法,就可以很方便的得到低功率的照明灯。如原来为220伏15瓦的灯泡,此时就成为7.5瓦了;
2.因为灯泡承受的电压降低了30%,避免了夜间市电电压过高对灯泡造成的损坏;
3.因为流过灯泡的电流也降低了30%,根据钨丝点燃理论可知,流过钨丝的电流若降低5%,寿命即提高一倍,因而灯泡的寿命可以大大的提高。
附图为本实用新型实施电路原理图。下面结合附图对本实用新型做进一步说明。
图中1为整流二极管,2为220伏普通白炽灯泡,二者串联并制成一体,成为一种低功率、可通宵长明的楼道照明灯具。
