目前,生产的光电头有时是采用凸透镜,有的是把光敏元件装在玻璃罩中,以此来采集散光信号去控制光电开关,其灵敏度较低,为此,笔者利用汽车前车灯制成了光电开关头,应用在我厂路灯光电控制器中,提高了光电头对散弱光的灵敏度,控制器控制时间正确,获得了较好效果。现作介绍。 At present, the production of optical head is sometimes convex lens, and some are the photosensitive elements installed in the glass cover, in order to collect astigmatism signal to control the photoelectric switch, the lower sensitivity, for which I use the car before the lights made of photovoltaic Switch head, used in our factory street light photoelectric controller, improve the sensitivity of the photoelectric head to weak light, the controller control time is correct, get good results. Introduce now.
