Abstract
一种发光二极管封装包含:N个分别接收N个电源信号的第一端,N=4、6;六个第二端;N个发光二极管单元,每个发光二极管单元包括第一至第三发光二极管,每个发光二极管具有第一及第二电极,第(2j‑1)及第2j个发光二极管单元中的所述第一发光二极管的所述第一电极电连接第(2j‑1)个第一端,所述第(2j‑1)及第2j个发光二极管单元中的所述第二及第三发光二极管的所述第一电极电连接第2j个第一端,j≦N/2,且j为正整数;当N=4时,第一与第三个发光二极管单元中每一者的所述第一至第三发光二极管的所述第二电极分别电连接第一至第三个第二端,第二与第四个发光二极管单元中每一者的所述第一至第三发光二极管的所述第二电极分别电连接第四至第六个第二端。
Description
技术领域
本发明涉及一种封装,特别是涉及一种发光二极管封装。
背景技术
参阅图1,现有发光二极管模块1适用于接收一个电源信号Vcc,且包含多个发光二极管(Light Emitting Diode,LED)封装11及多个限流电阻110。每个发光二极管封装11包括一个与所对应的限流电阻110串联连接的第一发光二极管111、一个第二发光二极管112及一个第三发光二极管113。于每个发光二极管封装11中,所述第一至第三发光二极管111、112、113的阳极彼此电连接并接收该电源信号Vcc,且据以分别发出红光、绿光及蓝光。
由于每个第一发光二极管111的制作材料不同于每个第二及第三发光二极管112、113的制作材料(每个第二及第三发光二极管112、113的制作材料相同),使得每个第一发光二极管111发光时的顺向电压(为2V)不同于每个第二及第三发光二极管112、113发光时的顺向电压(为3V)。因此,在上述结构中,为避免所述第一至第三发光二极管111、112、113发光时,每个第一发光二极管111因被过电压驱动而造成漏电或烧毁的问题出现,对于现有发光二极管模块1而言,用来减少所对应的每个第一发光二极管111的跨压的每个限流电阻110是必要构件。如此,将造成现有发光二极管模块1具有很高的能量损耗(此会导致现有发光二极管模块1累积不必要的热能,长期下来会造成每个发光二极管封装11中每个第一至第三发光二极管111、112、113的自身材料变质,进而降低每个发光二极管封装11的发光效率,甚至衍生每个发光二极管封装11有产品失效等可靠度问题),并导致现有发光二极管模块1具有较复杂的电路结构及较高的制造成本。
发明内容
本发明的目的在于提供一种能够克服先前技术缺点的发光二极管封装。
本发明的发光二极管封装,包含N个第一端、六个第二端、N个发光二极管单元及基板。
该N个第一端适用于分别接收N个电源信号,N=4、6。
每个发光二极管单元包括第一发光二极管、第二发光二极管,及第三发光二极管,且所述第一至第三发光二极管中的每一者具有一个第一电极及一个第二电极,第(2j-1)个发光二极管单元及第2j个发光二极管单元中的所述第一发光二极管的所述第一电极电连接第(2j-1)个第一端,所述第(2j-1)及第2j个发光二极管单元中的所述第二及第三发光二极管的所述第一电极电连接第2j个第一端,j≦N/2,且j为正整数。

本发明的发光二极管封装,当N=6时,所述第一与第三个发光二极管单元及第五个发光二极管单元中每一者的所述第一至第三发光二极管的所述第二电极分别电连接所述第一至第三个第二端,所述第二与第四个发光二极管单元及第六个发光二极管单元中每一者的所述第一至第三发光二极管的所述第二电极分别电连接所述第四至第六个第二端。
本发明的发光二极管封装,于每个发光二极管单元中,所述第一至第三发光二极管中每一者的该第一电极及该第二电极分别为一个阳极及一个阴极。
本发明的发光二极管封装,于每个发光二极管单元中,所述第二及第三发光二极管的制作材料相同,所述第一发光二极管的制作材料不同于所述第二发光二极管。

本发明的发光二极管封装,于每个发光二极管单元中,所述第一发光二极管发出红光,所述第二发光二极管发出绿光,所述第三发光二极管发出蓝光。
本发明的有益的效果在于:通过将每个发光二极管单元中的该第一发光二极管的该第一电极电连接一个第一端,所述第二及第三发光二极管的所述第一电极电连接另一个第一端,可避免每个第一发光二极管被过电压驱动而造成漏电或烧毁的问题出现,进而不须额外配置限流电阻。
附图说明
图1是一个电路图,说明一个现有发光二极管模块;及
图2是一个电路图,说明本发明发光二极管封装的一个实施例。
具体实施方式
参阅图2,本发明发光二极管(Light Emitting Diode,LED)封装20的一个实施例包含四(即,N=4)个第一端Ni1、Ni2、Ni3、Ni4、六个第二端No1、No2、No3、No4、No5、No6、四(即,N=4)个发光二极管单元2及一个基板(图未示)。在本实施例中,该四个第一端Ni1~Ni4、该六个第二端No1~No6及该四个发光二极管单元2被设置于该基板上。该发光二极管封装20为一个多像素封装体,每个第二端No1~No6是分别作为该多像素封装体的多个外接电极(即,该多像素封装体的接脚或焊接垫)。多个该发光二极管封装20用来组合成一个发光二极管模块(图未示)。
该四个第一端Ni1~Ni4适用于分别接收四个电源信号VCC1、VCC2、VCC3、VCC4。在本实施例中,每个电源信号VCC1、VCC3的电压值小于每个电源信号VCC2、VCC4的电压值。每个电源信号VCC1~VCC4是由一个定电压源或一个定电流源所提供。
所述发光二极管单元2中的每一者包括一个第一发光二极管21、一个第二发光二极管22,及一个第三发光二极管23。所述第一至第三发光二极管21、22、23中的每一者具有一个第一电极及一个第二电极。
第(2j-1)个发光二极管单元2及第2j个发光二极管单元2中的所述第一发光二极管21的所述第一电极电连接第(2j-1)个第一端Ni(2j-1),所述第(2j-1)及第2j个发光二极管单元2中的所述第二及第三发光二极管22、23的所述第一电极电连接第2j个第一端Ni(2j),j≦N/2(N/2=4/2=2),且j为正整数(等同于0<j≦N/2,且j为整数)。也就是说,当N=4时,j=1、2。举例来说,在本实施例中,当j=1时,第一及第二个发光二极管单元2中的所述第一发光二极管21的所述第一电极电连接第一个第一端Ni1,所述第一及第二个发光二极管单元2中的所述第二及第三发光二极管22、23的所述第一电极电连接第二个第一端Ni2。此外,所述第一与第三个发光二极管单元2中每一者的所述第一至第三发光二极管21、22、23的所述第二电极分别电连接第一个第二端No1、第二个第二端No2及第三个第二端No3。所述第二与第四个发光二极管单元2中每一者的所述第一至第三发光二极管21、22、23的所述第二电极分别电连接第四个第二端No4、第五个第二端No5及第六个第二端No6。
需说明的是,在本实施例中,于每个发光二极管单元2中,所述第一至第三发光二极管21、22、23中每一者的该第一电极及该第二电极分别为一个阳极及一个阴极。于每个发光二极管单元2中,所述第二及第三发光二极管22、23中每一者的制作材料为氮化铟镓(InGaN),该第一发光二极管21的制作材料为磷化铝铟镓(AlGaInP)。此外,于每个发光二极管单元2中,该第一发光二极管21发出红光,该第二发光二极管22发出绿光,该第三发光二极管23发出蓝光。
另外,本发明发光二极管封装20中,N的数量也可为六,但不限于此。当N=6时,j≦3(N/2=6/2),也就是说,j=1、2、3,且所述第一个发光二极管单元2、第三个发光二极管单元2及第五个发光二极管单元(图未示)中每一者的所述第一至第三发光二极管21、22、23的所述第二电极分别电连接所述第一至第三个第二端No1~No3,所述第二发光二极管单元2、第四个发光二极管单元2及第六个发光二极管单元(图未示)中每一者的所述第一至第三发光二极管21、22、23的所述第二电极分别电连接所述第四至第六个第二端No4~No6。
综上所述,本发明发光二极管封装20中,由于每个发光二极管单元2中的该第一发光二极管21所接收的电源信号VCC1(VCC3)不同于所述第二及第三发光二极管22、23所接收的电源信号VCC2(VCC4),也就是说,该第一发光二极管21是被单独控制,进而该第一发光二极管21不会如图1的现有第一发光二极管111是与第二及第三发光二极管112、113一起被控制(即,若没设置限流电阻110的话,会导致该第一发光二极管111有被过电压驱动而漏电或烧毁的问题出现),所以通过本发明发光二极管封装20所组合而成的该发光二极管模块可省略于图1的现有发光二极管模块1中所必须的多个限流电阻110。因此,该发光二极管模块相较于现有发光二极管模块1具有较低的能量损耗(如此,可避免该发光二极管模块累积不必要的热能,进而可增加本发明发光二极管封装20的可靠度)、较简单的电路结构及较低的制造成本。
以上所述者,仅为本发明的实施例而已,当不能以此限定本发明实施的范围,即凡依本发明权利要求书及说明书内容所作的简单的等效变化与修饰,皆仍属本发明的范围。
