Description

LED封装结构及使用该封装结构的LED灯
技术领域
本发明涉及一种封装结构及使用该封装结构的灯,特别是涉及一种LED封装结构及使用该封装结构的LED灯。
背景技术
传统的LED封装结构包括芯片、电极引线、封装外壳和焊接脚,LED的焊接脚为金属引脚,该金属引脚内端焊电极引线至芯片,外端用于与PCB线路板的焊接。为了实现LED的电导通,需将LED先焊接在PCB线路板上,再将供电的正负极导线分别焊在PCB线路板的焊盘上。如2011年8月24公告,专利号为201120074659.3的中国实用新型揭示了一种LED新型多功能大功率LED灯,它包括散热芯片(1)、LED芯片(2)、负极引脚(3)、正极引脚(4)和金绑定线(6),它还包括驱动芯片(5),该驱动芯片(5)和金绑定线(6)焊接在散热芯片(1)上的相应焊接位,且驱动芯片(5)与LED芯片(2)通过导线焊连。这种方法需通过焊接才能实现驱动芯片的导线与LED芯片的电连接,但是在一些尺寸较小的灯具产品中,其内部容置空间很小,电烙铁焊接导线时作业困难,耗费工时。
发明内容
有鉴于此,有必要提供一种便于组装的LED封装结构及使用该封装结构的LED灯。
一种LED封装结构,包括LED芯片、座体、两条金线及两个电连接件,该座体上设有收容槽,该LED芯片及所述金线收容在该收容槽内,每个电连接件均包括连接端及导电片,该连接端设有导线固定结构,该导电片伸入该收容槽内,通过该金线与该LED芯片电连接。
一种LED灯,包括基板、导线、驱动器和LED封装结构,该LED封装结构包括LED芯片、座体、两条金线及两个电连接件,该座体上设有收容槽,该LED芯片及所述金线收容在该收容槽内,每个电连接件均包括连接端及导电片,该连接端设有导线固定结构,该导电片伸入该收容槽内,通过该金线与该LED芯片电连接,该LED封装结构固定在该基板上,该基板上设有导线过孔,该导线一端插入该LED封装结构的电连接件的连接端内与该LED芯片电连接,另一端与驱动器电连接。
与现有技术相比,该LED封装结构通过将该两电连接件的导电片封装在该座体的收容槽内,使该两电连接件的连接端可以通过金线与这些LED芯片电连接,并在该连接端上设置导线固定结构,使得驱动器上的导线可以直接插入该连接端内。从而省去了现有技术中的人工焊接步骤,使得该LED封装结构及使用该封装结构的LED灯具有便于组装的优点。

具体实施方式
请参照图1至图4,本发明第一实施例的LED封装结构100包括一座体10、一透镜20、四个LED芯片30、两条金线50及两个电连接件40。这些电连接件40固定在该座体10内,这些LED芯片30收容在该座体10内,这些金线50与这些LED芯片30电连接。
请参照图5,使用本发明第一实施例的LED封装结构100的LED灯200包括LED封装结构100、基板120、两个导线110。该LED封装结构100固定在该基板120,该基板120上设有导线过孔121。该两导线110一端分别与该LED封装结构100电连接,另一端穿过该导线过孔121与一驱动器电连接。
该两个电连接件40的结构相同,均由金属导电材料制成。每个电连接件40均包括一连接端41和一导电片42,该连接端41与该导电片42由一金属片一体卷绕成型。该连接端41为卷绕形成的圆筒环结构,且该连接端41的内侧壁设置有弹片412,该圆筒结构及该弹片412组成该连接端41的导线固定结构。该导电片42从该连接端41的一侧向外延伸。
请参照图2及图4,该座体10的中部设有收容槽13,用于容置这些LED芯片30。,该透镜20设置在该收容槽13开口的上方。该座体10的两端分别设有一限位孔11,该两限位孔11分别用于收容该两电连接件40的连接端41(如图4所示),该两连接端41分别与该限位孔相对应平行设置。该两限位孔11分别与外界连通,使得该两导线110能插入该限位孔11中并进入该连接端41内与该电连接件40电连接(如图5所示)。当该导线110的线芯插入该连接端41内,该线芯使得该弹片412弹性变形,在该弹片412的弹性回复力作用下,该导线110的线芯被限定在连接端41内,同时与连接端41实现电连接。该连接端41的孔径与供电导线110的线芯横截面直径的比例为0.9~1,使得连接端40内的弹片412对供电导线110线芯的限位和电连接效果更好。
请参照图4,这些LED芯片30之间通过LED连接线32串联连接,这些电连接件40的导电片42伸入该收容槽13内,通过该金线50与这些串联的LED芯片30的两端电连接,形成闭合回路。该收容槽13内设有封装胶,该座体10的上表面与该收容槽13对应处设有圆形树脂透镜20。
该LED封装流程包括以下步骤:1、将连接端41和导电片42一体卷绕成型,放置在该热沉的两侧;2、环绕该热沉部分放置模子,通过注射成型来形成底座10,且在中间形成收容槽13;3、用银浆或锡膏将LED芯片30固定在座体10的热沉的中间;4、将LED芯片30的金丝通过金丝球焊技术与导电片42连接;5、往收容槽13内注入透明树脂;6、将树脂透镜20固定在座体10上表面与收容槽13对应处。
请参照图5,在将该LED封装结构100组装至该LED灯200上时,只需将该LED封装结构100固定在整灯200的基板120上,然后驱动电路的输出导线110只需穿过该基板120的过孔121后插入该LED封装结构100的电连接件40的连接端41内,在弹片412的作用下,该驱动电路的输出导线110的线芯端就被固定在该连接端41中,从而实现该LED芯片30与驱动电路的电连接。
综上所述,该LED封装结构100通过将该两电连接件40的导电片42封装在该座体10的收容槽13内,使该两电连接件40的连接端41可以通过金线50与这些LED芯片30电连接,并在该连接端41上设置导线固定结构,使得驱动器上的导线110可以直接插入该连接端41内。从而省去了现有技术中的人工焊接步骤,使得该LED封装结构100具有便于组装的优点。这些LED芯片之间通过LED连接线串联连接,从而只需将驱动电路的输出导线110的线芯部分插入该电连接件40的连接端41中,即可实现对多个LED芯片30供电。组装该LED灯200时,只需将该LED封装结构100固定在基板120上,通过在基板120上设置导线过孔121,使得驱动电路的输出导线110可通过这些过孔121与LED封装结构100电连接,结构简单,便于自动化生产。
可以理解的,该两电连接件40也可以采用其他结构,例如,该连接件40的连接端41可为常规电源插座中插孔内的弹片结构,而不必采用卷绕成型。该连接端41只要能实现与该座体10的相对固定即可,而不必收容在该座体10内。在该连接端41设置导线固定结构的目的在于确保有效的电连接,也可以采用其他常规技术手段代替。例如,在该导线110的末端设置弹片(图未示)等扣接结构,将该连接端41设置成光滑的圆环结构,利用导线110上弹片的回复力将该导线110的末端嵌接在该连接端41的内侧壁,也可以实现稳固的电连接。这些LED芯片30之间也可以并联连接。
