用于自动调光恒光台灯的光电传感器 Photoelectric sensor for automatic dimming constant light table lamp
技术领域 Technical field
本实用新型涉及一种用于自动调光恒光台灯的光电传感器。 The utility model relates to a photoelectric sensor for automatically dimming a constant light table lamp.
背景技术 Background technique
根据国际照明标准读写的照度是 500LX, 中国照明标准读写的照度是 300LX, 其误差是 ± 10%。亮度过高或过低就会对人眼产生不良影响， 是近视 眼发病率的主要原因之一， 而真正地了解这个原因的人不多， 除了少数专家 以外。 据有关报道： 近视眼是影响大约三分之一人口严重视力问题， 在美国 的成人中 15%~25%有近视眼， 而大多数在 7岁以前没有近视问题。根据， 理 论推算， 全世界患近视眼的人可能超过 50%, 中国近视眼发生率超过 70%, 近视眼的发生率和严重程度随着受教育水平的增加而增加。 我国患近视眼人 数居世界之首。 在近视眼患者中， 学生是主流。 其中小学生的发病率为 22.78%, 高中生为 70.34%, 大学生则高达 76.74%。 目前， 这一数字仍呈上 升趋势。 虽然目前市面上有调光台灯， 第一种类型的台灯是手动调节亮度， 这样一来， 使用者不知灯的亮度多少对眼睛有利或有害， 是否符合照明标准。 即使知道， 因为环境亮度经常变化， 所以人们需要用照度计不断地去测量照 度， 调整台灯作业面的照度值； 第二种类型的台灯是自动调节亮度， 但是这 类台灯， 虽然能够根据环境光调整台灯的亮度， 但是这类台灯不能保持其台 灯作业面的照度值符合照明标准或基本点保持不变。 这样一来， 这两种台灯 的使用者不知灯的亮度多少对眼睛有利或有害， 是否符合照明标准。 即使知 道， 因为环境亮度经常变化， 所以人们需要用照度计不断地去测量照度， 调 整台灯作业面的照度值； 这种做法在日常工作和生活中实际上是很难做到的。 也就是往往不去调节亮度， 认为只要眼睛能够看得清楚就行， 懒得去调整亮 度。 The illuminance of reading and writing according to international lighting standards is 500LX, and the illumination of Chinese lighting standard reading and writing is 300LX, and the error is ± 10%. Too high or too low brightness can have adverse effects on the human eye and is one of the main causes of myopia incidence. There are not many people who really understand this cause, except for a few experts. According to related reports: Myopia is affecting about one-third of the population's serious vision problems. 15% to 25% of adults in the United States have myopia, and most of them have no nearsightedness before the age of 7. According to the theoretical calculations, the number of people suffering from myopia in the world may exceed 50%, the incidence of myopia in China exceeds 70%, and the incidence and severity of myopia increase with the increase of education level. The number of people suffering from myopia in China ranks first in the world. In myopic patients, students are the mainstream. Among them, the incidence rate of primary school students is 22.78%, that of high school students is 70.34%, and that of college students is 76.74%. At present, this figure is still on the rise. Although there are currently dimming lamps on the market, the first type of desk lamp is to manually adjust the brightness, so that the user does not know how much the brightness of the lamp is beneficial or harmful to the eyes, and whether it meets the lighting standards. Even if you know, because the ambient brightness often changes, people need to constantly measure the illuminance with the illuminometer and adjust the illuminance value of the working surface of the desk lamp; the second type of desk lamp is to automatically adjust the brightness, but this kind of table lamp can be based on ambient light. Adjust the brightness of the desk lamp, but this type of desk lamp can't keep the illumination value of the desk lamp working surface to meet the lighting standard or the basic point remains unchanged. In this way, the users of the two lamps do not know how much the brightness of the lamp is beneficial or harmful to the eyes, and whether it meets the lighting standards. Even knowing Road, because the ambient brightness often changes, so people need to use the illuminometer to constantly measure the illuminance, adjust the illuminance value of the work surface of the desk lamp; this practice is actually very difficult to do in daily work and life. That is to say, it is often not necessary to adjust the brightness. It is considered that as long as the eyes can see clearly, it is too lazy to adjust the brightness.
