我们研制了一种简易光点指示器.曾在1988年4月自治区第二届发明与新技术成果展览会上受到欣赏和好评,同时也有人提出:此体积偏大,偏重(450g).我们新近又用下述方法使光点指示器与投影仪结合为一体.光点指示器与投影仪是由微动开关,电源线,单掷开关及4.8V 灯泡,灯座、镜头和6 V 交流变压器等组成.1.取四股电缆线,将两股四端与投影灯电源变压器输入端的电路相连接.其中将一股线串联在单掷开关上,以此作为光点指示器上的外控开关.
We developed a simple spot indicator, which was appreciated and praised at the 2nd Autonomous Region Invention and New Technology Exhibition in April 1988. At the same time, it was also suggested that this volume is too large and weighed (450g). Recently, the spot indicator and the projector have also been integrated as follows: The spot indicator and the projector are composed of a micro switch, a power cord, a single-throw switch and a 4.8 V lamp, a lamp holder, a lens, and a 6 V AC Transformers, etc. 1. Take four cables, the four ends of the projector lamp power transformer with the input circuit connected to which a wire connected in series with the single-throw switch, as a spot indicator on the external control switch.
