Abstract

一种电子视力保护圆珠笔,它是在已有的圆珠笔上安装有光敏电阻,安装有检测光照强度的电路板,安装有可指示光照强度的发光二极管。使得人们在使用时,便捷检测环境照度,预防视力疲劳,预防近视,非常适用于现代人们追求视力健康生活、学习的需求。

Description

电子视力保护圆珠笔
本实用新型涉及一种视力保护圆珠笔,特别是一种电子视力保护圆珠笔。
目前,公知的圆珠笔为单纯的圆珠笔,使用时,受本身的制约,无法得知书写环境光照度是否符合要求,已落后于现代人们追求视力健康的生活、学习要求:
本实用新型的目的,就是为克服上述缺陷提供一种电子视力保护圆珠笔。
本实用新型的目的是这样实现的,视力保护圆珠笔上安装有光敏电阻,安装有可指示光照强度的发光二极管,安装有检测光照强度的电路板。由于安装有检测光照强度的电路板,通过光敏电阻检测到环境光照度,可指示出环境光照强度,有效的预防视力疲劳,预防近视,电子视力保护圆珠笔不受环境光照不足的制约。
由于采用上述技术方案,可实现电子视力保护圆珠笔的预防视力疲劳,预防近视的便捷。
下面结合附图和实例对本实用新型进一步说明。
图1是本实用新型的电路图
图2是本实用新型的半剖示意图
图2中:1、外壳;2、开关;3、光敏电阻;4、绿色发光二极管;5、红色发光二极管;6、笔芯。
如图所示的电子视力保护圆珠笔外壳1,开关2,光敏电阻3,绿色发光二极管4;红色发光二极管5;笔芯6。使用时,先将开关2打开,光敏电阻3检测环境光照度符合要求时,绿色发光二极管4亮,光线低于标准照度时,红色发光二极管5发出闪光,以示警告。关毕开关,使用过程完毕。
由于本实用新型上述的特点,非常适用于现代人们追求视力健康生活、学习的需求。
