1993年初起，我们在原有鼻镜的基础上配上光源，既可取代额镜又提高了检查效果，现介绍如下：1．结构原理和制作：带灯光鼻镜是由鼻镜、小聚光灯泡、灯泡插座、电源线和电源等组成。1．灯泡选用手电筒的3V聚光灯泡；灯泡插座：取一块薄铜片制成“T”形，尺寸见附图，制成后固定 From the beginning of 1993, we added a light source on the basis of the original nose lens, which can replace the frontoscope and improve the inspection results. Now it is introduced as follows: 1. Structural principle and production: The nose with light is composed of a nose lens, a small spotlight bulb, a light bulb socket, a power cord and a power supply. 1. The light bulb uses a 3V spotlight for the flashlight; the bulb socket: Take a thin piece of copper to make a “T” shape. See the drawing for dimensions and fix it after making it.
