Description

LED灯丝球泡灯
本申请要求于2015年03月14日提交中国专利局、申请号为201510110777.8、发明名称为“LED灯丝球泡灯”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及灯具技术领域，具体涉及一种LED灯丝球泡灯。
背景技术
LED灯丝球泡灯在日常生活中很普及，目前常见的LED球泡灯如图8所示，现有灯丝球泡灯的灯丝3一般与固定在芯柱4上的支撑导线43电连接，再通过设在芯柱4上的导线与泡壳2外的驱动电源5电连接，所述芯柱还需包含一支撑杆4-1，用于固定上端的支撑导线43，进而用于支撑灯丝3，一般的灯丝3有四根，而在芯柱上与灯丝3电连接的导线也会有四条，但由于芯柱4的体积有限，四条导线之间容易造成短路，所以在生产中要特别注意；另外现有的灯丝球泡灯的驱动电源5一般放置在泡壳2外的灯头1内，但由于灯头1为金属材料，驱动电源5通电后会与灯头形成电磁感应，并产生电磁干扰，容易在EMC认证中出问题，另外为了驱动电源5能有足够的空间装在灯头1内，现有技术一般还在泡壳2与灯头1之间设置有一塑料连接件6，但是增加了塑料连接件6，在灯丝球泡灯装配工艺工序中，无疑是加大了工艺难度，无法很好地提高产品的生产效率，而且还增多了塑料连接件6的生产成本，再者塑料连接件6的散热效果较差，影响驱动电源产生的热量的散发，从而影响灯丝球泡灯的寿命。
发明内容
鉴于以上所述，本发明有必要提供一种结构新颖、安全性高、并且可节省材料成本，提高生产效率的LED灯丝球泡灯。
一种LED灯丝球泡灯，包括灯头、泡壳、以及LED灯丝发光组件，所述泡壳连接在灯头上，所述LED灯丝发光组件包括驱动电源，所述驱 动电源设置在泡壳内。
进一步地，所述LED灯丝发光组件包括芯柱、所述驱动电源安装在芯柱上。
进一步地，所述芯柱的顶端凸伸有一插接凸柱，所述驱动电源的一端开设有与所述插接凸柱匹配的插接槽以配合固定驱动电源。
进一步地，所述芯柱上设有导线，所述导线与驱动电源的电路导接。
进一步地，所述导线凸伸在所述芯柱的顶端，所述驱动电源上开设有一对导接位与所述导线插接。
进一步地，所述LED灯丝发光组件包括若干支架杆以及若干LED灯丝，若干支架杆安装在驱动电源上以固定若干LED灯丝，此结构，驱动电源不仅用于驱动LED光源，同时还起到支撑灯丝的作用，节省了传统的灯丝球泡灯中的支撑杆的部件。
进一步地，所述若干支架杆穿插过驱动电源并通过铆接或焊接的方式与驱动电源固定电连接。
进一步地，述支架杆末端弯曲成弧线段或连接弧线段以围绕驱动电源的上端或下端，所述LED灯丝固定在上下弧线段之间。
进一步地，所述芯柱包括柱体和设置在柱体上的支柱，所述支柱上设有一容置孔，以容置所述驱动电源。
进一步地，所述芯柱包括一压盖，封盖在支柱容置孔的顶端。
进一步地，所述压盖包括盖合部及凸伸在盖合部上的握柄，盖合部与容置孔的顶端配合，所述LED灯丝发光组件包括若干支架杆，若干支架杆侧伸在握柄外周与柱体的外周。
进一步地，所述压盖与支柱一体设置，支柱的容置孔的开口向下，并且与柱体卡合连接。
进一步地，所述驱动电源为长形板状结构的驱动电路板，且驱动电路板的板面具有反光层。
进一步地，所述驱动电路板的表面涂有起隔热作用的环氧树脂层。
相较于现有技术，本发明LED球泡灯通过将驱动电源设置在泡壳内，改进了传统的驱动电源设置在灯头内的安装结构，避免了驱动电源置于灯 头内时与金属灯头靠得太近，容易造成电磁干扰的现象，另外本球泡灯省去了塑料连接件，不仅节省了塑料连接件的材料成本，缩短了整灯的尺寸，使球泡灯更加紧凑美观，而且简化了灯泡的装配工序，可实现机械化生产，提高生产效率，灯丝直接通过支架杆与驱动电源电连接，也减少了芯柱上导线，结构更加安全。

此外，芯柱31内还形成有一排气管36，排气管36一端于喇叭口313中心处伸出，另一端向上延伸贯通芯柱31与泡壳20内腔连通。
驱动电源32可插接卡固在芯柱31上，为长形板状结构，可以是矩形板体，也可以是异形板体。本第一较佳实施例中，驱动电源32呈矩形板体结构，为驱动电路板，板体表面设置有若干电子元件。驱动电源32与芯柱31连接的一端开设有插接槽以及导接位，插接槽配合芯柱31顶端的插接凸柱314，导接位配合芯柱31顶端的导线35，使得驱动电源32稳固安装在芯柱31上，并且驱动电源32的电路与芯柱31上的导线35导接。
结合参阅图4、图5，若干支架杆33侧伸固定在驱动电源32的上下两端，通过上下两根支架杆33配合以支撑固定LED灯丝34。所述支架杆33穿插在驱动电源32上，支架杆33的中间位置通过焊接或铆接的方式与驱动电源32固定电连接。上端的支架杆33绕驱动电源32上端等距环绕分布，下端的支架杆33绕驱动电源32下端等距环绕分布，且一上端支架杆33对应一下端支架杆33，组成一对支架杆33以支撑固定LED灯丝34，其中， 上端的支架杆33侧伸的长度较下端支架杆33侧伸的长度短，如此，安装后的若干灯丝34可围成圆梯台状。本实施例中，支架杆33为四根金属线，上下各两根，金属线分别穿过驱动电源板上的电导接穿孔后再向侧水平弯曲，形成上四根等长度且均匀分布的支架杆和下四根等长度且均匀分布的支架杆，对应的灯丝34为四根，每一根灯丝34分别连接在一对支架杆33上。本另一实施例还可以是在驱动电源板上下各设置一根支架杆33，灯丝34固定电连接在上下两根支架杆33之间。进一步的，所述支架杆33可以分别弯曲成弧线段或连接弧线段围绕驱动电源32上端或下端，也可在各支架杆33两端分别焊接分支杆，灯丝固定在弧线段之间或分支杆之间时，并联分布在驱动电源32四周，还可以是弯弧线段与分支杆两种方式的结合。可以理解，支架杆33具有电性导通作用，上端的支架杆33导通一极性的导线35，下端的支架杆33导通另一极性的导线35。LED灯丝34的排列也可根据不同需求而有所改变。本发明的LED灯丝通过支架杆将灯丝固定在驱动电源上，再将驱动电源放置在灯泡内，不仅解决了，驱动放置于球泡中位置非常有限的问题，而所述驱动电源不仅用于驱动光源，还替代支撑杆4-1，起支撑LED灯丝的作用，又节省了材料，结构布置非常紧凑合理。
此外，为了便于泡壳20内光线散出，驱动电路板的板面具有反光作用的反光层，优选的，电路板的板面可以直接采用白色绝缘的材质制成或在板面上涂覆一层绝缘反光层。LED灯丝发光组件30封接在泡壳20内时，泡壳20的底部收缩的开口端与喇叭口313通过高温烧熔封接，再通过排气管36向泡壳20内充入惰性气体后烧结密封，密封好的泡壳通过灯头泥固定在灯头10上，两根导线35分别电性连接灯头10外周的螺纹面11，与灯头10底端的焊锡或铆钉12。
在优选的实施方式中，所述驱动电路板的表面可以涂有环氧树脂层，以起到隔热作用；或者，本领域技术人员可以在驱动电路板的表面涂覆其他能够起隔热作用的材料，以取代所述环氧树脂层作为隔热层。换言之，本领域技术人员可以根据需要选择隔热材料，不限于上述环氧树脂，只要能够起到隔热作用即可。
请参阅图6，本发明第二较佳实施例所示的一种LED灯丝球泡灯200，收容在泡壳20内的LED灯丝发光组件40与第一较佳实施例中的LED灯丝发光组件30结构略有不同。LED灯丝发光组件40包括芯柱41、驱动电源42、若干支架杆43以及若干LED灯丝44。芯柱41上设置有导线45，驱动电源42安装在芯柱41上，并且驱动电源42的电路与芯柱41上的导线45导接。
芯柱41收容在泡壳20内与泡壳一体固定连接在灯头10上，芯柱41包括空心柱体411、支柱412以及设置在支柱412顶端的压盖413。支柱412一体设置在柱体411的顶端，且支柱412顶端向下沿轴向开设有一容置孔414，以容置所述驱动电源42，所述支柱412可以是空心圆柱、方柱，也可以是空心的异形柱体。压盖413安装在支柱412的顶端，封盖支柱容置孔414。本第二较佳实施例中，压盖413包括盖合部及凸伸在盖合部上的握柄，盖合部与容置孔414顶端配合。安装驱动电源42时，将驱动电源42从容置孔414顶端置入，然后将压盖413封盖容置孔411即可。若干支架杆43形成在芯柱41的外周，通过支架杆43支撑固定LED光源30。若干支架杆43侧伸设置在芯柱41的外周上、下两端，通过每一上、下两支架杆43连接每一LED灯丝44的两端，从而将LED灯丝44固定在芯柱41上。本第二较佳实施例中，上端支架杆43侧伸连接在压盖413的握柄上，下端支架杆43侧伸在柱体411的外周，且较上端支架杆43侧伸的半径范围长，使得LED灯丝44呈坡度设置。
LED灯丝发光组件40还可以在芯柱41的外周面上设置反光层，用于反射LED灯丝44发出的光线，同时还能遮住芯柱41内设置的驱动电源42，更加美观。本第二较佳实施例中，反光层涂覆在支柱412的外周面上。
请参阅图7，本发明第三佳实施例所示的一种LED灯丝球泡灯300，其结构大致与第二较佳实施例中的LED灯丝球泡灯200结构相同，其区别在于：本第三实施例中，压盖413与支柱412一体设置，支柱412上的容置孔414的开口端向下，并可通过扣合或者粘结等方式固定在柱体411上，在安装驱动电源42时，先将驱动电源42放置在容置孔414内，再将支柱412卡固在柱体411上。
综上，本发明LED球泡灯通过将驱动电源设置在泡壳内，改进了传统的驱动电源设置在灯头内的安装结构，避免了驱动电源置于灯头内时与金属灯头靠得太近，容易造成电磁干扰的现象，比较容易通过EMC认证，另外本球泡省去了塑料连接件，不仅节省了塑料连接件的材料成本，缩短了整灯的尺寸，使球泡更加紧凑美观，而且简化了灯泡的装配工序，可实现机械化生产，提高生产效率，灯丝直接通过支架杆与驱动电源电连接，也减少了芯柱上导线，结构更加安全。
只要不违背本发明创造的思想，对本发明的各种不同实施例进行任意组合，均应当视为本发明公开的内容；在本发明的技术构思范围内，对技术方案进行多种简单的变型及不同实施例进行的不违背本发明创造的思想的任意组合，均应在本发明的保护范围之内。
