Description

发光二极管封装结构
一、技术领域
本实用新型涉及发光二极管(LED),特别是在照明领域中表面贴装的发光二极管封装结构。
二、背景技术
在传统的照明中,白炽灯和高压钠灯来说,主要能量都被热能消耗了,所以电能的利用率非常低,造成资源的浪费和环境的破坏。而发光二极管是将电能转换成光能的器件,并且转换率高达以上响应时间快的优点,在工作环境稳定的情况下能够使用寿命高达10万小时左右,所以不易损坏。
在传统的发光二极管封装在照明中得到了广泛的应用,根据二极管的单相导通特性,发光二极管是直流电压下工作,需要电压也是非常低,只要超过门槛电压就可以触发。现在在发光二极管的照明应用中,都是配套一起开关电源供直流电压。因为每颗发光二极管的功率小,光照达不,所以在发光二极管的灯具电路中都是串联,或者是并联几组串联的发光二极管,这样的情况下,电源开关如果电压不稳定,串联中有一个发光二极管有问题,这个一组都不亮。而传统发光二极管照明都是在陶瓷基座上进行贴片封装。要连陶瓷基座一起更换。既困难,又浪费材料。因此,其改进和创新势在必行。
三、发明内容
针对上述情况,为克服现有技术之缺陷,本实用新型之目的就是提供一种发光二极管封装结构,可有效解决发光二极管更换困难,浪费材料的问题。
本实用新型解决的技术方案是,包括芯片、透镜、金线、凹形反射座和陶瓷基座,凹形反射座的凹槽底部有银胶,芯片由银胶固定在凹形反射座的凹槽内,芯片经金线与导电金属片相连接,凹形反射座的凹槽内灌装有透明胶层,透明胶层及凹形反射座的上部边沿上,固定封装有透镜,凹形反射座内壁有反射层,凹形反射座装在陶瓷基座的中部凹槽内,导电金属片经导线与陶瓷基座上的导线相连,构成导电回路。
本实用新型结构简单,新颖独特,易生产,成本低,LED灯更换简便,节约材料。
四、附图说明
图1是本实用新型单颗结构主视图。
图2是本实用新型封装结构图。
五、具体实施方式
以下结合附图对本实用新型的具体实施方式作详细说明。
由图1-图2给出,本实用新型包括芯片、透镜、金线、凹形反射座和陶瓷基座,凹形反射座的凹槽底部有银胶5,芯片4由银胶5固定在凹形反射座1的凹槽内,芯片经金线3与导电金属片7相连接,凹形反射座的凹槽内灌装有透明胶层6,透明胶层及凹形反射座1的上部边沿上,固定封装有透镜2,凹形反射座内壁有反射层8,凹形反射座装在陶瓷基座9的中部凹槽内,导电金属片7经导线与陶瓷基座上的导线10相连,构成导电回路。
为了保证使用效果,所说的陶瓷基座9和凹形反射座1上部的边沿由固定胶11粘接在一起,固定胶外有绝缘介质层12;所说的陶瓷基座9中部有和凹形反射座外壁形状相一致的凹槽。
由上述结构可以看出,本实用新型是每一颗发光二极管都是独立的单元,如果需要更换只需要单颗更换,不是在pcb板或陶瓷板等上进行的贴片打线焊接,而是独立的单元体,本实用新型可大量生产,为发光二极管等基座板做配件,这样就解决了发光二极管灯中,一组中的一个有问题,一组都不亮的更换困难的问题。
本实用新型是在绝缘塑料的凹形槽里进行固定芯片和金线焊接,金线使芯片和金属片完成电性连接,金属片是凹槽座内部通到凹槽座外部的导电金属。进行灌透明胶和盖透镜后,形成一个独立的器件。通过金属片与散热基座上面的导电回路进行接触后导通,因为散热基座与凹槽座的外壁成楔状,压的越紧,就越接触好,通过在散热底座的凹槽外沿涂胶,然后压紧烘干,完成组装。
本实用新型是用凹槽式倒杯状封装外壳,所以打线和涂银光粉后的灌胶较容易进行,因为这样灌胶时的液体会均匀分布,不会出现传统凸凹不平的现象。
本实用新型在生产时,根据图1图2所示,是在凹形反射座1的凹槽底部进行涂银胶5,然后进行贴芯片4,再进行烘箱烘烤,待到完全烘干,银胶5固定好芯片4后,进行打金线3。金线3使芯片4与导电金属片7完成电性连接。然后进行灌胶,形成透明胶层6,灌胶是为了固定和保护芯片4和金线3不被氧化腐蚀,震动等。透明胶可以来固定和粘牢透镜2,透明胶不会阻挡芯片发光的光线。凹形反射座内壁有反射层8,反射层是为了芯片光照射后反射,是光亮度增强。然后盖透镜,盖透镜是为了强光亮,这样就形成了一个独立发光二极管装置。
散热座9中间做成和凹形反射座外壁形状一样凹槽。这样当把做好的独立发光二极管装置放到散热座的凹槽中,因为是“到v”型,所以压的越紧就会使导电金属片7与导电回路10的的触点越接触好,在基座9的凹槽的外沿一周涂上固定胶11,用固定胶11把凹形反射杯1和基座9粘接起来,粘接的同时要保证导电金属片7与导电回路10的触点接触良好,能够完成芯片4与外部导电回路相通,固定好后完成封装。
