Description

发光二极管封装构造 技术领域
本发明涉及一种发光二极管封装构造,特别是涉及一种将所述发光二极管芯片及所述稳压二极管分隔设在不同区域的发光二极管封装构造。
背景技术
液晶显示器(liquid crystal display,LCD)是利用液晶材料的特性来显示图像的一种平板显示装置(flat panel display,FPD),其相较于其他显示装置而言更具轻薄、低驱动电压及低功耗等优点,已经成为整个消费市场上的主流产品。然而,液晶显示器的液晶材料无法自主发光,必须借助外在提供光源,因此液晶显示器中又另外设有背光模块以提供所需的光源。
一般而言,背光模块可分为侧入式背光模块和直下式背光模块两种形式。已知背光模块主要是以冷阴极荧光灯管(CCFL)、热阴极荧光灯管(HCFL)及半导体发光组件作为光源,而半导体发光组件主要又是利用发光二极管(LED)进行发光,其相较于阴极荧光灯管更为省电节能、使用寿命更长,且体积更为轻巧,因而有逐渐取代阴极荧光灯管的趋势,发光二极管将是液晶显示器的背光模块未来的主要光源。
现今,发光二极管多以芯片的形式进行半导体封装,以作为发光二极管封装构造,最后再与背光模块的固定板接合。发光二极管产品封装构造的类型,有根据发光颜色、晶粒材料、发光亮度、尺寸大小等情况特征来分类的。单个晶粒一般构成点光源,多个晶粒组装一般可构成面光源和线光源,作信息、状态指示及显示用,发光显示器也是用多个晶粒,通过晶粒的适当连接(包括串联和并联)与合适的光学结构组合而成的,构成发光显示器的发光段和发光点。其中,表面粘着封装型的LED(SMD-LED)是贴于电路板表面,适合SMT加工,可回流焊,可有效解决亮度、视角、平整度、可靠性、一致性等问题,其也采用了更轻的PCB板和反射层材料,改进后去掉了直插引脚式LED较重的碳钢材料引脚,使显示反射层需要填充的环氧树脂更少,表面粘着封装LED可轻易地将产品重量减轻一半,最终使应用更加完美。因此,表面粘着封装型的LED已逐渐替代直插引脚式LED,应用设计更灵活,特别是在LED显示市场中占有一定的份额,有加速发展趋势。
请参照图1所示,图1揭示一种现有发光二极管封装构造的剖视图。如图1所示,一种现有发光二极管封装构造90包含:一壳体91、一第一电极片92、一第二电极片93、一发光二极管芯片94、一稳压二极管95及一透光封装部96。所述壳体91的顶面设有一凹部911;所述第一电极片92的一部分裸露于所述凹部911的底部,另一部分延伸至所述壳体91外,以使用于与外部的电性连接;所述第二电极片93的一部分裸露于所述凹部911的底部,另一部分延伸至所述壳体91外,以使用于与外部的电性连接;所述发光二极管芯片94裸露于所述凹部911之内,其第一电极电性连接于所述第一电极片上,其第二电极通过一第一引线941电性连接于所述第二电极片93;所述透光封装部96,填补于所述凹部911并且封装所述凹部911内之各组件,所述发光二极管芯片94的光线能通过所述透光封装部96向上方发射。
然而,在现有的所述发光二极管封装构造90中,为了使所述发光二极管芯片94避免由于静电而被击穿,往往会并联一个或一组所述稳压二极管95来解决这样的问题。请同时参照图1及图2所示,其中图2是图1的现有发光二极管封装构造的电路示意图。在所述发光二极管封装构造90中,所述稳压二极管95是设于所述壳体91之上,亦即设于所述第二电极片93之上,其第一电极位于下端电性连接于所述第二电极片93上,其第二电极位于上端通过一第二引线951电性连接于所述第一电极片92。也就是说,所述稳压二极管95与所述发光二极管芯片94是形成并联的状态,且所述稳压二极管95是呈反向偏压的设置。因此,所述稳压二极管95可以起到保护所述发光二极管芯片94避免被静电击穿的功用。但是,所述稳压二极管95是设置于所述第二电极片93的上方,即位于所述壳体91的上方,也就是位于所述透光封装部96之内。并且,由于所述稳压二极管95的外观是无法透光且多呈现黑色的,因此,所述稳压二极管95因具有挡光及吸光的性质,会引影响到所述发光二极管芯片94的部分光通量,降低所述发光二极管封装构造90的发光效能。
故,有必要提供一种发光二极管封装构造,以解决现有技术所存在的问题。

本发明的最佳实施方式
为让本发明上述目的、特征及优点更明显易懂,下文特举本发明较佳实施例,并配合附图,作详细说明如下:
请同时参照图3及图4所示,图3揭示本发明第一实施例的发光二极管封装构造的俯视图;图4揭示本发明第一实施例的发光二极管封装构造的剖视图。如图3及图4所示,本发明第一实施例的发光二极管封装构造10包含:一壳体11、一第一电极片12、一第二电极片13、一发光二极管芯片14及一稳压二极管15。所述壳体11的顶面设有一凹部111,所述凹部111是一凹陷构造,图3及图4是以一种基本的形态来表示,其具体形状可依产品需求而调整。所述凹部111内包含一挡墙111a,所述挡墙111a将所述凹部111分为一发光区111b及一稳压区111c,所述挡墙111a是插设于所述凹部111或与所述壳体11一体成型而成。
再者,所述第一电极片12的一部分裸露于所述发光区111b的底部,一部分裸露于所述稳压区111c的底部,及有一部分延伸至所述壳体11外,以用于与外部的电性连接;所述第二电极片13的一部分裸露于所述发光区111b的底部,一部分裸露于所述稳压区111c的底部,及有一部分延伸至所述壳体11外,以用于与外部的电性连接。
另外,所述发光二极管芯片14设于所述发光区111b之内,且设于所述第一电极片12上,所述发光二极管14具有一第一电极(未标示)及一第二电极(未标示)。所述第一电极电性连接于所述第一电极片12上,所述第二电极电性连接于所述第二电极片13上;在本实施例中,所述发光二极管芯片14优选是分别通过导电银胶或引线电性连接于所述发光区111b内的所述第一电极片12及所述第二电极片13。如图3及图4所示,本发明第一实施例的一个可能的情况是:所述发光二极管芯片14的所述第一电极(未标示)通过一引线141电性连接于所述第一电极片12上,所述第二电极(未标示)通过一引线142电性连接于所述第二电极片13上。但本发明并不限于此,例如,在另一可能的实施例中,所述发光二极管芯片14的第一电极可能位于底部,并通过导电银胶与所述第一电极片12直接贴合且电性连接。
再者,所述稳压二极管15是设于所述稳压区111c之内,所述稳压二极管15也具有一第一电极(未标示)及一第二电极(未标示)。所述第二电极电性连接于所述第一电极片12上,所述第一电极电性连接于所述第二电极片13上。所述稳压二极管15优选是分别通过导电银胶或引线电性连接于所述稳压区111c内的所述第一电极片12及所述第二电极片13。如图3及图4所示,本发明第一实施例的一个可能的情况是:所述稳压二极管15的所述第二电极(未标示)通过通过一引线151电性连接于所述第一电极片12上,所述第一电极(未标示)通过一导电银胶152电性连接于所述第二电极片13上。但本发明并不限于此,在另一可能的实施例中,所述稳压二极管15的所述第一电极也可能通过引线与所述第二电极片13电性连接。
如图4所示,所述挡墙111a的高度与所述壳体11的一外墙的高度相等,所述发光区111b及所述稳压区111c是完全的被所述挡墙111a隔开。因此所述发光二极管封装构造10另包含一第一封装部及一第二封装部(未标示),其分别封装在所述发光区111b及所述稳压区111c内,所述第一封装部用以包覆保护位于所述发光区111b的第一电极片12、第二电极片13及发光二极管芯片14,所述第二封装部用以包覆保护位于所述稳压区111c的第一电极片12、第二电极片13及稳压二极管15。其中封装所述发光区111b的所述第一封装部必须为一透光封装部,其材质为适用于封装并且能透光的材质,例如环氧树脂,这样所述发光二极管芯片14的光线才能通过所述封装部向上方发射。
然而,本发明的所述封装部并不限于此,再另一可能的实施例中,所述挡墙111a的高度可能低于所述壳体11的外墙的高度,而所述发光二极管封装构造10只需要一封装部即可同时封装所述发光区111b及所述稳压区111c,当然在此状况下的所述封装部也必须为一透光封装部。
另外,所述发光二极管芯片14为了避免由于静电而被击穿,因此需要设置至少一所述稳压二极管15,并且所述稳压二极管15的极性配置是:其第二电极(未标示)在上端及第一电极(未标示)在下端,所述稳压二极管15的下端第一电极通过导电银胶152电性连接于所述第二电极片13,所述稳压二极管15的上端通过引线151电性连接于所述第一电极片12,因此所述稳压二极管15与所述发光二极管芯片14形成并联,且所述稳压二极管15是反向偏压。然而本发明并不限于此,所述稳压二极管15可选择各种不同的型式,并通过各种方式来电性连接于所述第一电极片12或所述第二电极片13。在一可能的实施例中,所述稳压二极管15可以是第一电极及第二电极都在上端的型式,并且都通过引线以电性连接至所述第一电极片12及所述第二电极片13。
综上所述,在本发明的发光二极管封装构造10中,由于所述发光二极管芯片14与所述稳压二极管15是被所述挡板111a分隔在不同的区域(所述发光区111b及所述稳压区111c),不论所述挡墙111a的高度与所述壳体11的外墙的高度是否相等(所述发光区111b及所述稳压区111c是完全或不完全的被所述挡墙111a隔开)。相对于所述发光二极管芯片14,所述挡板111a都能起到隔离所述稳压二极管15的功能,其避免因所述稳压二极管15吸收光线而影响到所述发光二极管芯片14的光通量,从而提高了整体发光二极管封装构造10的发光效能。
另外,本发明并不指定所述第一电极、所述第二电极、所述第一电极片12及所述第二电极片13所代表的极性,在一通常的情况下,所述第一电极可能是指阳极(正极),而所述第二电极可能是指阴极(负极),但也有可能是所有极性对应状况的排列组合。并且,虽然本发明第一实施例所揭示的所述发光二极管封装构造10设有一个所述稳压二极管15,然而,本发明并不限制所述稳压二极管15的数量,使用者可依实际需要设置多个所述稳压二极管15。
请再参照图5及图6所示,图5揭示本发明第二实施例的发光二极管封装构造的俯视图;图6揭示本发明第二实施例的发光二极管封装构造的剖视图。如图5及图6所示,本发明第二实施例的发光二极管封装构造10相似于本发明第一实施例的发光二极管封装构造10,因此沿用相同的组件符号与名称,但其不同之处在于:本发明第二实施例的发光二极管封装构造10另包含一热沉金属片16,所述热沉金属片16一部分裸露于所述发光区111b之内,一部分延伸至所述壳体11外,并且所述发光二极管芯片14是设于所述热沉金属片16上。所述发光二极管芯片14通过所述引线141及所述引线142电性连接所述第一电极片12及所述第二电极片13。由于所述发光二极管芯片14的底面是贴设于所述热沉金属片16上,并且所述热沉金属片16有一部分延伸至所述壳体11外部,因此所述发光二极管芯片14产生的热能可通过所述热沉金属片16被导出所述发光二极管封装构造10的外部,形成一种电热分离的型式。
另外,在本发明第二实施例中,所述挡墙111a的高度是低于所述壳体11的外墙的高度,而所述发光二极管封装构造10包含一封装部同时封装所述发光区111b及所述稳压区111c,以包覆保护位于所述发光区111b的第一电极片12、第二电极片13、热沉金属片16及发光二极管芯片14,以及包覆保护位于所述稳压区111c的第一电极片12、第二电极片13及稳压二极管15,并且所述封装部为一透光封装部。
在本发明第二实施例中,所述挡墙111a的高度亦可以与所述壳体11的外墙的高度相等,所述发光二极管封装构造还包含一第一封装部(未标示)及一第二封装部(未标示),分别封装在所述发光区111b及所述稳压区111c内,所述第一封装部用以包覆保护位于所述发光区的第一电极片12、第二电极片13、热沉金属片16及发光二极管芯片14,所述第二封装部用以包覆保护位于所述稳压区111c的第一电极片12、第二电极片13及稳压二极管15,所述第一封装部为一透光封装部。
再者,虽然本发明的图3及图4揭示了一种所述第一电极片12及所述第二电极片13的配置情形;以及本发明的图5及图6揭示了另一种所述第一电极片12、所述第二电极片13及所述热沉金属片16的配置情形。然而本发明并不限于此,使用者可依照实际需求设计所述第一电极片12、所述第二电极片13及所述热沉金属片16的配置型式,并且搭配所述发光二极管芯片14及所述稳压二极管15配置于所述第一电极片12、所述第二电极片13或所述热沉金属片16上的各种可能情况的排列组合。
综上所述,相较于现有的发光二极管封装构造的稳压二极管是设置于壳体的上方,其影响到发光二极管芯片的部分光通量,因而降低所述发光二极管封装构造的发光效能。本发明的所述发光二极管封装构造10的所述凹部111内包含一挡墙111a以分隔为一发光区111b及一稳压区111c,并将所述发光二极管芯片14及所述稳压二极管15分隔设置在不同的区域,以避免因所述稳压二极管15吸收光线而影响到所述发光二极管芯片14的光通量,从而提高了所述发光二极管封装构造10的整体发光效能。
本发明已由上述相关实施例加以描述,然而上述实施例仅为实施本发明的范例。必需指出的是,已公开的实施例并未限制本发明的范围。相反地,包含于权利要求书的精神及范围的修改及均等设置均包括于本发明的范围内。
