背光模块及其使用的可分离式光源连接装置Backlight module and detachable light source connection device used therefor

技术领域technical field

本发明关于一种背光模块及其使用的可分离式光源连接装置。The invention relates to a backlight module and a detachable light source connection device used therein.

背景技术Background technique

背光模块广泛使用于液晶显示装置、电脑键盘、移动电话按键、广告看板及其它需要光源的装置上，以提供此类装置所需的平面光源。特别是近年来液晶显示装置的市场需求大幅成长，为配合液晶显示装置在功能上及外观上的要求，液晶显示装置所使用的背光模块设计也日趋多元化。Backlight modules are widely used in liquid crystal display devices, computer keyboards, mobile phone buttons, advertising billboards and other devices that require light sources to provide the planar light sources required by such devices. In particular, in recent years, the market demand for liquid crystal display devices has grown significantly. In order to meet the functional and appearance requirements of liquid crystal display devices, the designs of backlight modules used in liquid crystal display devices are also increasingly diversified.

一般而言，供液晶显示装置所使用的背光模块需要有良好的输出光源均匀性，以使液晶显示装置的显像效果均匀。传统上的背光模块主要分为侧光式及直下式两种，其中直下式的背光模块具有产生光源面积较不受限的优点。如图1所示，在直下式的背光模块中，将数支灯管10直接并列设置于灯管托架70之上。灯管10的端部伸出连接于电极的导丝11。导丝11与导线50焊接，导线50再延伸到连接器60，连接器60则与换流器30电连接。Generally speaking, the backlight module used for the liquid crystal display device needs to have good uniformity of the output light source so as to make the image display effect of the liquid crystal display device uniform. Traditionally, backlight modules are mainly divided into two types: edge-lit and direct-lit. Among them, the direct-lit backlight module has the advantage that the area of the light source is not limited. As shown in FIG. 1 , in the direct type backlight module,several lamp tubes 10 are directly arranged side by side on thelamp tube bracket 70 . Aguide wire 11 connected to an electrode protrudes from the end of thelamp tube 10 . Theguide wire 11 is welded to thewire 50 , and thewire 50 extends to theconnector 60 , and theconnector 60 is electrically connected to theconverter 30 .

然而当需要重工或检修背光模块时，此一传统的灯管组装设计需将各部零件分别拆下，因此造成其过程的困难度，并容易造成损伤。此外，此一传统的组装流程通常较为耗时，进而增加整体的生产成本。However, when the backlight module needs to be reworked or repaired, this traditional lamp assembly design needs to disassemble each part separately, which makes the process difficult and easy to cause damage. In addition, this traditional assembly process is usually time-consuming, thereby increasing the overall production cost.
