Description

节电携带式电子装置
【技术领域】
本发明是关于一种节电携带式电子装置，尤其是关于一种利用外部光源作为背光光源的节电携带式电子装置。
【背景技术】
随着通信技术的快速发展，携带式电子装置，如移动电话，功能不断翻新。显示屏幕呈现越来越大的趋势，显示屏幕色素升级到26万色甚至更高级别，拍照功能奔向数百万像素级别，加上高音质铃声、内置游戏、视频播放等应用迅速普及，移动电话的功能越来越强大，耗电量也越来越大。一般移动电话不论是在白天或者晚上、光线充足与否，移动电话呼入、呼出特别是移动电话的按键受到碰触时，如使用者在把玩移动电话时，移动电话的显示屏和按键的背光都会激活，而移动电话的背光会消耗电池的大量电能。由于移动电话电池的发展落后于移动电话功能的发展，如果同时使用移动电话的多种功能，移动电话的待机时间将会较短，导致有些耗电比较大的功能成为虚设，直接影响移动电话各种功能的使用。
【发明内容】
有鉴于此，提供一种可以利用外部光源作为背光光源以省电的节电携带式电子装置十分必要。
一种节电携带式电子装置，包括一本体，其包括一屏幕部和一反射装置；该屏幕部包括一LCM模组和一遮盖LCM模组的屏幕护盖，该屏幕护盖具有一用以接收外部光线的聚光部；该反射装置固定在本体上，其将聚光部所汇聚的光线反射到LCM模组。
相较已知技术，所述节电携带式电子装置可在外部光源充足时关闭LED光源而利用外部光源作为LCM模组的背光光源，可节省该携带式电子装置的电力。
【附图说明】
图1是本发明节电携带式电子装置一较佳实施例的分解立体图；
图2是本发明节电携带式电子装置一较佳实施例的剖视图。
【具体实施方式】
请参阅图1和图2所示，本发明节电携带式电子装置一较佳实施例包括一本体10，该本体10具有一屏幕部12，该屏幕部12包括一液晶显示模组122(Liquid Crystal Module，以下简称LCM模组)、一屏幕护盖124、一第一反射片126和一第二反射片128。
该本体10一端设有多个按键102，其内容置有电路板等电子元件。该本体10另一端具有一凹部14，该凹部14呈V形，其包括一前壁142和一与该前壁142相连接的后壁144。
该屏幕部12的LCM模组122设置在本体10的凹部14内，且与本体10内收容的电路板相电连接，其位置与凹部14后壁144相对应，且未遮盖凹部14的前壁142。该LCM模组122包括一用于接收背光光源的导光板(图未示)，该导光板可将其接收的光源均匀化，以达到均匀照明的目的。该屏幕护盖124设置在LCM模组122上方并封闭本体10的凹部14，其可保护LCM模组122不受外力损害，和避免粉尘等杂质进入凹部14污染LCM模组122而影响LCM模组122的显示效果。该屏幕护盖124是一透明镜片，其包括一透光部1241和一聚光部1242。该透光部1241与LCM模组122的位置相对应，使用者可通过该透光部1241查看LCM模组122所显示的信息。该聚光部1242采用凸透镜、菲涅耳透镜等具有聚光效果的设计，其与凹部14前壁142相对应，其可将外部光线20，如日光、灯光等，汇聚到凹部14的前壁142上。该第一反射片126固设在凹部14的前壁142上，其将聚光部1242汇聚到此的光线反射向凹部14的后壁144。该第二反射片128固设在凹部14的后壁144上，其具有散射功能，可将第一反射片126反射的光线散射到LCM模组122处，为LCM模组122提供背光光源。该第一反射片126和第二反射片128均具有高反射率。该第一反射片126和第二反射片128可连接为一体成为一反射装置，也可以是分离式设计。
使用该节电携带式电子装置时，外部光线20经由屏幕护盖124的聚光部1242汇聚到固设在凹部14前壁142上的第一反射片126上，然后经由第一反射片126反射到固设在凹部14后壁144上的第二反射片128，再经由第二反射片128散射到LCM模组122成为其背光光源。使用者在外部光线20充足时，可关闭该节电携带式电子装置的LED(Low Emitting Diode，发光二极管)背光光源，利用外部光线20背光，以达到节电的目的。
可以理解，该节电携带式电子装置可进一步包括一光传感器(图未示)，如一光敏电阻，该光传感器设置在该节电携带式电子装置的可接收外部光线20处，且其与该节电携带式电子装置的控制LED背光光源启闭的控制模组相电连接。该控制模组可接收光传感器感测的外部光线20的光强信号，并据此信号的强弱自动开启或关闭LED背光光源。如此，可以达到自动选择使用外部光源或使用LED光源的目的，方便使用者的使用。
