Abstract

本发明提供一种背光模组，包含一框架单元、一设置于该框架单元上的光源，及一设置于该框架单元上并用以接收该光源所发散的光线的导光板。该框架单元包括一呈横向设置的侧板、一设置于该侧板的一侧且呈纵向设置的背板，及一设置于该背板上的导热板，其中，定义该背板的高度为H，该背板具有一底缘、一距离该底缘1/4H至1/3H的预定区域，及一位于该预定区域内且呈横向延伸的贯穿槽，该导热板的高度是不高于该贯穿槽。透过该贯穿槽形成一绝热设计，大幅减少该光源产生的热传导至该背板相对上方的位置，有效防止该背板因热产生弯折的现象。

Description

背光模组
技术领域
本发明是有关于一种光源模组，特别是指一种背光模组。
背景技术
背光模组已被广泛地应用于制作各式平面显示器，而平面显示器的薄形化已经逐渐成为趋势。背光模组通常包括光源、背板，及导光板等结构，在整体结构越朝向薄形化设计时，背板相当容易受到光源所产生的热所影响，而产生弯折(bending)的现象。
目前最常见的作法是设置导热片，用以将光源所产生的热进行传导以加速散热。然而上述设计仍无法有效改善背板因热所产生的弯折现象。
发明内容
因此，本发明的目的，即在提供一种有效防止背板因热弯折的背光模组。
于是本发明背光模组，包含一框架单元、一设置于该框架单元上的光源，及一设置于该框架单元上并用以接收该光源所发散的光线的导光板。该框架单元包括一呈横向设置的侧板、一设置于该侧板的一侧且呈纵向设置的背板，及一设置于该背板上的导热板，其中，定义该背板的高度为H，该背板具有一底缘、一距离该底缘1/4H至1/3H的预定区域，及一位于该预定区域内且呈横向延伸的贯穿槽，该导热板的高度是不高于该贯穿槽。其中，该光源是设置于该侧板上，而该导光板是对应该光源设置。
本发明的功效在于：透过于该背板上开设有贯穿槽，并使该导热板位于该贯穿槽的相对下方，将该光源所产生的热限制于该背板位于该贯穿槽下方的区域，使该贯穿槽形成一绝热设计，大幅减少该光源产生的热传导至该背板相对上方的位置，有效防止该背板因热产生弯折的现象。
附图说明
本发明的其他的特征及功效，将于参照图式的实施方式中清楚地呈现，其中：
图1是一侧视图，说明本发明背光模组的一较佳实施例；及
图2是一前视图，辅助说明图1。
其中，图中各标示为：2背光模组；3框架单元；30外框；31侧板；32背板；321底缘；322预定区域；323贯穿槽；33导热板；4光源；41发光二极体；5导光板；H高度；L长度。
具体实施方式
参阅图1与图2，本发明背光模组2的一较佳实施例，包含一框架单元3、一设置于该框架单元3上的光源4，及一设置于该框架单元3上并用以接收该光源4所发散的光线的导光板5。该框架单元3包括一外框30、一呈横向设置于该外框30上的侧板31、一设置于该侧板31的一侧且呈纵向设置的背板32，及一设置于该背板32上的导热板33。其中，该光源4是设置于该侧板31上，并包括多个间隔设置的发光二极体41(因视角的关系图1中只显示一个)。该导光板5是设置于该外框30上并对应该光源4，但要特别说明的是，该外框30的整体结构以及该外框30与该导光板5之间的连结关系并非本案的重点，不再另外绘示及赘述。
其中，定义该背板32的高度为H，该背板32具有一底缘321、一距离该底缘321的1/4H至1/3H的预定区域322，及一位于该预定区域322内且呈横向延伸的贯穿槽323。定义该背板32的长度为L，该贯穿槽323的长度为至少80%×L。该导热板33的高度是不高于该贯穿槽323。另外，于本实施例中，该背板32的贯穿槽323是位于该预定区域322的相对中央处。
当所述发光二极体41运作而产生热时，会经由该侧板31传导至该导热板33，再传导至该背板32。由于该导热板33位于该贯穿槽323的相对下方，因此热会被限制于该背板32位于该贯穿槽323下方的区域，该贯穿槽323则形成一绝热设计，大幅减少热传导至该背板32相对上方的位置，有效防止该背板32因热产生弯折的现象。
综上所述，本发明背光模组2，透过于该背板32上形有该贯穿槽323，并限制该贯穿槽323设置的位置与尺寸，在兼顾该背板32的结构强度下使该贯穿槽323形成一绝热设计，大幅减少热传导至该背板32相对上方的位置，有效防止该背板32因热产生弯折的现象，故确实能达成本发明的目的。
惟以上所述者，仅为本发明的较佳实施例而已，当不能以此限定本发明实施的范围，即大凡依本发明申请专利范围及专利说明书内容所作的简单的等效变化与修饰，皆仍属本发明专利涵盖的范围内。
