黑光灯是农林害虫予测予报的重要工具,同时用于防治某些具有趋光性的害虫,也有良好效果。但交流电黑光灯,目前在农业生产上的广泛应用,还受着电源、电线、电杆等条件的限制。我所在党组织、革委会的领导下,由于昌黎县电讯局的大力帮助,我所植保技术人员于一九七二年十一月仿制成一台6伏电源,输出8瓦的半导体黑光灯。以后又在天津市通讯器件厂的帮助下改进提高,又制出一台输出6瓦的6伏直流电源的半导体黑光灯,经试用性能良好。现正由天津通讯器材厂、唐山无线电三厂研究筹办成批生产。半导体黑光灯结构比较简单(如下图),在普通黑光灯上安一个电瓶和半导体装置
Black light is an important tool for forest and animal pests to be reported to the newspaper, at the same time for the prevention and control of certain phototropic pests, but also has good results. However, AC black light is widely used in agricultural production and is also limited by the conditions of power supply, electric wire and electric pole. Under the leadership of our party organization and the Revolutionary Committee, thanks to the help of Changli County’s telecommunications bureau, our plant technicians copied a 6-volt power supply and exported 8-watt semiconductor black lights in November 1972. Later, with the help of Tianjin Communication Device Factory, the company improved and produced a 6-volt DC semiconductor black light lamp with output of 6 watts. The trial performance is good. Now by the Tianjin Communications Equipment Factory, Tangshan Radio III plant research preparation batch production. Semiconductor black light structure is relatively simple (as shown below), in a normal black light on a battery and semiconductor devices
