摘要
设计并研制了"人工眼"照度定量判别器,它是利用光电转换器、运算放大器和警示线路,可及时定量判别某一工作面的照明是否符合照度标准的要求.如果过亮或太暗,由警示装置作出提示,从而对人的视力进行保护.
Brief Introduction： Off - standard illumination can harm human eyes. The fact of too many nearsighted students indicates that this is an important problem. The artificial eye quantitative illumination discriminator designed and developed here can be used to decide quantitatively if the illumination on a working surface is in conformity to the requirement of standard illumination by means of photoelectric converter, operational amplifier, and alarm circuit. If the illumination is too high or too low, the alarm device will give out indication to offer protection to human vision.
