Abstract

本实用新型是一种适合夜间野外无光源条件下作业的人员书写用的夜光笔。利用发光二极管作光源,电源置于笔杆内,通过旋转笔套控制电源通断。该夜光笔具有光照度好,耗电量小,生产成本低等优点,也可兼作弱光照明用。实用性好,具有推广价值。

Description

本实用新型涉及一种书写笔,特别是一种能在夜间无照明情况下书写的夜光笔。
通常的笔本身均无照明装置,一些夜间野外作业人员,如矿勘、铁路、军事等操作人员需借助光源才能书写,给作业带来麻烦。为了解决这一问题,曾有人设想在笔杆上设置一小电珠,但因其照光度不够或耗电量过大而无法实施。
本实用新型的目的是要提供一种自带光源、且耗电量极微的夜光笔,以解决无光源条件下的书写问题。
本实用新型的技术方案是这样实现的:在普通圆珠笔的笔尖部,设置一发光二极管,笔芯尖从二极管中心圆孔中穿出,电源置于笔杆上端,通过开关控制电源的通断。
图1为本实用新型的示意图。
以下将结合附图对实施例进行详细描述。
参照图1,在普通圆珠笔的笔杆头部,装入一中心留有圆孔的圆锥形发光二极管1,管的下半端裸露在杆外,笔芯2从笔杆中段联接处穿入,直至笔芯尖从发光二极管中心孔穿出后定位。电源3采用1.8伏以上金属电池,其正极直接与发光二极管连接,负极则通过开关4再与二极管接通,开关4利用旋转笔套来控制。弹簧5起压紧定位作用,以防触点松动。
本实用新型具有照明度好、耗电量小、生产成本低,携带方便的优点,也可兼作微光照明使用,具有实用价值。
