一台灭蚊灯,因原灯管损坏而无法使用。笔者应急使用日光灯启辉器的内部氖泡和纸质小电容器代替灯管,同样吸引蚊虫。大家知道,日光灯启辉器的内部装有一个氖泡和一只4700～5100pF 的纸质小电容器,它们的接法是并联的,要让氖泡在交流220V 的电路中长明,只要将氖泡和电容改为串联即可,通电时氖泡发出桔黄色的亮光,放在房间里吸引蚊虫。固定氖泡是用一块长为13cm,宽为4cm 的三合板打眼穿孔放入栅栏中间(接
A mosquito lamp, because of the original lamp damage can not be used. The author of emergency use fluorescent lamp starter internal small neon bulb and paper instead of small capacitors, also attract mosquitoes. We all know, fluorescent lamp starter with a neon bulb and a 4700 ~ 5100pF small paper capacitors, the connection is parallel, so that the neon bulb in the exchange of 220V circuit in the long, as long as the neon Bubbles and capacitors can be changed in tandem, the neon bulb emits orange light when energized, and places the mosquito in the room. Neon bubble is fixed with a length of 13cm, width of 3cm perforation into the fence in the middle of the plywood
