Description

一种LED筒灯
技术领域
本实用新型涉及照明灯具技术领域，尤涉及一种LED筒灯。
背景技术
筒灯是典型的无主灯、无定规模的现代流派照明，能营造室内照明气氛，若将一排小射灯组合起来，光线能变幻奇妙的图案。由于小射灯可自由变换角度，组合照明的效果也千变万化。筒灯可安置在吊顶四周或家具上部，也可置于墙内、墙裙或踢脚线里，在一些专业的摄影场合还安装在轨道上，其应用场合十分广泛。然而，现有的筒灯其通用性不强，在特定的场合只能搭配具有特定安装结构的筒灯，如果将某个筒灯的使用场合进行更换，则需要重新再更换新的安装结构，给安装及使用带来不便。
现有一种易拆装的LED筒灯，包括灯杯、设置于灯杯内的LED铝基板、设置于LED铝基板上部的散热装置以及设置于灯杯下部的外环，所述散热装置连接有与外环固定连接的弯折延伸件，延伸件弯折处向散热装置延伸方向设有通孔，所述通孔处设有衔接装置。这种LED筒灯容易安装并且拆卸简便，解决了现有筒灯拆装不便的问题，但其外环的加工工序复杂并且成本较高。
实用新型内容
针对现有技术的缺点，本实用新型提供了一种组装工艺简便的LED筒灯，加工工序简单，并且成本低廉。
为解决上述技术问题，本实用新型采用的技术方案是：
一种LED筒灯，包括反光杯、设置于反光杯内的LED铝基板、设置于LED铝基板上部的散热器、固定于散热器下部的外环以及设置于反光杯下部的透镜，其特征在于：所述反光杯与外环之间设有外环饰件，外环饰件的一端与透镜连接、另一端设置于散热器与外环之间。
改进之一，所述散热器连接有与外环固定连接的弯折延伸件，延伸件弯折处向散热器延伸方向设有通孔，所述通孔处设有衔接装置。衔接装置用于卡住筒灯使其固定在天花板或墙上，通孔的设计则便于调节衔接装置，使其可达到最大限度地扭转并贴紧延伸件，使LED筒灯的拆装更为灵活方便。
可选地，所述衔接装置为扭簧，如此可利用扭簧的弹性复位作用，通过外环将灯直接从天花板拉出。
其中，延伸件上通孔的尺寸为扭簧的安装尺寸。另外，延伸件弯折的角度没特殊要求,只是将顶部散热器延伸到外环固定,可根据反光杯的高度改变而改变。
改进之二，所述延伸件与散热器一体成型。一体成型更便于筒灯的制作，节省工序，并且安装方便，散热结构无需通过零件等结构连接延伸件。
改进之三，所述外环饰件的一端通过卡扣或紧配合结构与透镜固定连接，优选采用卡扣结构的连接方式，拆装更为方便；所述外环饰件的另一端设置于散热器与外环之间，散热器、外环饰件以及外环通过螺丝固定连接，由此可将散热器、外环饰件以及外环一次性压紧。
改进之四，所述外环和/或外环饰件为金属薄片。外环和/或外环饰件采用金属薄皮冲压成型，取代了现有筒灯采用铝毛胚件车制加工的外环结构，降低了原材料的成本，也降低了车制的成本。
与现有技术相比，本实用新型的有益效果是：
本实用新型LED筒灯，采用外环和外环饰件两个金属配件的组合，改进了现有筒灯的外环结构，减少了车制加工工序，并且有效降低了成本，增加了表面处理工艺的选择性，提高了LED筒灯的成品效果。
另外，改进结构的组装无需采用另外的组装工艺，只是简单叠加，再采用螺丝的固定方式一次性将散热器、反光杯、外环及外环饰件等一起压紧，操作简便，提高了工作效率。
附图说明
图1为本实用新型LED筒灯的结构剖视图；
图2为图1中A部分的放大示意图；
图3为本实用新型LED筒灯的整体结构示意图。
具体实施方式
下面结合具体实施方式对本实用新型作进一步的说明。
如图1至图3所示为本实用新型LED筒灯的实施例，包括反光杯1、设置于反光杯1内的LED铝基板2、设置于LED铝基板2上部的散热器3、固定于散热器3下部的外环4以及设置于反光杯1下部的透镜5，反光杯1与外环4之间设有外环饰件6，外环饰件6的一端与透镜5连接、另一端设置于散热器3与外环4之间。
该LED筒灯采用外环4和外环饰件6两个金属配件的组合，改进了现有筒灯的外环结构，减少了车制加工工序，并且有效降低了成本，增加了表面处理工艺的选择性，提高了LED筒灯的成品效果。
本实施例中，散热器3连接有与外环4固定连接的弯折延伸件7，延伸件7弯折处向散热器3延伸方向设有通孔8，通孔8处设有扭簧9。利用扭簧9的弹性复位作用，卡住筒灯使其固定在天花板或墙上，通过外环4将灯直接从天花板拉出。其中，通孔8的设计便于调节扭簧9，使其可达到最大限度地扭转并贴紧延伸件7，使LED筒灯的拆装更为灵活方便。
对于延伸件7弯折的角度没特殊要求,只是将顶部散热器3延伸到外环固定,可根据反光杯1的高度改变而改变，而延伸件7上通孔8的尺寸则为扭簧9的安装尺寸。
为了便于筒灯的制作，节省工序，使安装更为方便，延伸件7与散热器3一体成型，散热结构无需通过零件等结构连接延伸件7。实际生产加工时，外环饰件6的一端通过卡扣结构与透镜5固定连接、另一端设置于散热器3与外环4之间，散热器3、外环饰件6以及外环4通过螺丝固定连接，由此可将散热器3、外环饰件6以及外环4一次性压紧，采用这样的设计以增加安装的便利性。改进结构的组装无需采用另外的组装工艺，只是简单叠加，再采用螺丝的固定方式一次性将散热器3、反光杯1、外环4及外环饰件6等一起压紧，操作简便，提高了工作效率。
同时，外环4和/或外环饰件6采用金属薄皮冲压成型，取代了现有筒灯采用铝毛胚件车制加工的外环结构，降低了原材料的成本，也降低了车制的成本。
