除非另有定义，本文所使用的技术术语的含义与本申请所属技术领域的技术人员通常理解的含义相同；本文中对相关术语的使用只是为了描述具体的实施例，而不是旨在限制本申请。
在本申请的描述中，用语“和/或”是用于描述对象之间逻辑关系的表述，表示可以存在三种关系，例如A和/或B，表示：存在A，存在B，以及同时存在A和B这三种情况。另外，本文中字符“/”一般表示前后关联对象是一类“或”的逻辑关系。
在本申请中，诸如“第一”和“第二”之类的用语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何实际的数量、主次或顺序等关系。
在没有更多限制的情况下，在本申请中，语句中所使用的“包括”、“包含”、“具有”或者其他类似的表述，意在涵盖非排他性的包含，这些表述并不排除在包括所述要素的过程、方法或者产品中还可以存在另外的要素，从而使得包括一系列要素的过程、方法或者产品中不仅可以包括那些限定的要素，而且还可以包括没有明确列出的其他要素，或者还包括为这种过程、方法或者产品所固有的要素。
与《审查指南》中的理解相同，在本申请中，“大于”、“小于”、“超过”等表述理解为不包括本数；“以上”、“以下”、“以内”等表述理解为包括本数。此外，在本申请实施例的描述中“多个”的含义是两个以上(包括两个)，与之类似的与“多”相关的表述亦做此类理解，例如“多组”、“多次”等，除非另有明确具体的限定。

请参阅图1到图8，本实施例提供一种多级调节的伸缩灯，包括螺口灯头1、第一伸缩套管2、第二伸缩套管3、第三伸缩套管4、固定组件5、外架6、照明单元7、灯主体8和可转动组件9，优选地，伸缩套管为空心圆柱形。所述螺口灯头1的底端与所述第一伸缩套管2的顶端相连接，所述第一伸缩套管2与所述第二伸缩套管3滑动套接，所述第二伸缩套管3与所述第三伸缩套管4滑动套接，所述外架的顶部与所述第三伸缩套的底端连接。通过第一伸缩套管2、第二伸缩套管3和第三伸缩套管4形成多级可伸缩结构，增加伸缩灯的可伸缩长度，可以满足吊顶孔内的灯头与吊顶之间间距更大范围的伸缩灯的安装。所述第一伸缩套管2和所述第二伸缩套管3的底端分别设置有固定组件5，用于限制伸缩灯的拉伸长度，避免第二伸缩套管从第一伸缩套管内脱出，也避免第三伸缩套管从所述第二伸缩套管内脱出。所述照明单元7设置于所述灯主体8内部，所述外架6与所述灯主体8通过可转动组件9连接，这样灯主体可以实现在外架内的偏转，可以改变灯主体的照射角度，从而便于照射角度的调节。所述照明单元通过导线与所述螺口灯头电连接。其中，导线的长度略大于完全伸长时螺口灯头到照明单元的距离，导线一般采用软线，伸缩灯在收缩的时候，导线可以扭曲并置于收缩后的伸缩套管内。而后导线长度也要预留一部分长度给灯主体在外架内的偏转。由于本实用新型的灯主体在外架内仅仅是偏转，角度并非很大，所以只要将导线预留长一些即可满足转动需要。当然灯主体与外架支架要有间隔，即可以满足偏转需要，又可以容置导线。
本实用新型在实际使用时，先将螺口灯头与预设的灯座(一般是吊顶孔内的灯座)进行螺纹连接，并根据实际情景的使用需求调整第一伸缩套管2、第二伸缩套管3、第三伸缩套管4的拉伸长度，使得灯主体盖在吊顶孔处。当然在进行吊顶开口灯具的替换时，还可以先调节伸缩灯的伸缩长度，再将伸 缩灯螺旋连接至灯座。安装完成后，通过可转动组件9的转动使得灯主体8偏转，达到对照明单元7的照射角度进行调整的目的，可使伸缩灯适用于更复杂的使用场景，如不同的照明区域的需求。并且灯主体8与外架6的分体结构使得在维修时便于对灯主体8进行拆卸替换。
本实用新型进一步地，伸缩灯可进一步设置为三级以上(如四级，则需要再增加一个伸缩套管)的伸缩调节，这样伸缩长度更长，可以适应更多样的安装需求。
在本实用新型中，为了实现伸缩，每个伸缩套管中间用于伸缩接触部分的内径是相同的，且中间的外径也是相同的，这样在伸缩过程，伸缩套管相互之间的间距不会变化，可以使得伸缩结构稳定。优选的，所述第一伸缩套管2的外壁与所述第二伸缩套管3的内壁接触，所述第二伸缩套管3的外壁与所述第三伸缩套管4的内壁接触，使得伸缩过程中整体伸缩结构更加稳定。
在本实用新型中，固定组件5用于限制伸缩的位置，如图7所示，可以包括外套沿53和内凸沿54，外套沿53设置在在外的伸缩套管的顶部内周，内凸沿54设置在在内的伸缩套管的底部外周，这样在拉伸到最大长度的时候，在内的内凸沿54可以顶在外套沿53上，从而避免可以在内的伸缩套管从在外的伸缩套管内脱出。在某些实施例中，外套沿53可以采用其他形式实现，如所述第二伸缩套管3的上端和所述第三伸缩套管4的上端分别向内收缩，用于伸缩灯完全拉伸时，分别与第一伸缩套管2的固定组件5上端和第二伸缩套管3的固定组件5上端相接，避免拉伸时误操作过度拉伸，导致伸缩结构分离对伸缩灯造成损伤。优选的，所述固定组件5还包括弹性固定环50，所述弹性固定环50分别设置于第一伸缩套管2、第二伸缩套管3的底端外侧，第一伸缩套管2、第二伸缩套管3的底端的弹性固定环50分别与第二伸缩套管3、第三伸缩套管4的内壁相接，弹性固定环50在伸缩灯的伸缩过程中，通过自身的形变对两侧接触面产生作用力，使得第一伸缩套管2与第二伸缩套管3的相对位置以及第二伸缩套管3与第三伸缩套管4的相对位置实现固 定，最终使得伸缩灯可以实现伸缩长度的任意调节和固定。
优选的，第一伸缩套管2外侧设置有向外凸起的第一棱20，所述第一棱20与设置在所述第二伸缩套管3内侧相邻两个棱之间的空隙互相接触，所述第二伸缩套管3外侧设置有向外凸起的第二棱30，所述第二棱30与设置在所述第三伸缩套管4内侧相邻两个棱之间的空隙互相接触，通过棱与空隙的连接，使得伸缩灯在伸缩式不会由于操作原因出现偏移，并且由于减少了表面接触，减少摩擦力避免了伸缩出现卡顿的问题。
优选的，所述第三伸缩套管4的底端与所述外架6的顶端通过可旋转组件10连接，使得外架6可旋转，这样与可转动组件结合起来，可以更多角度地调节光源照射方向，外架6顶端中心设置有开口，用于穿过电线。外架的顶端可以直接与可旋转组件10连接，如图5所示，或者在某些实施例中，可以通过一个连接柱进行连接，如图6所示。这里需要说明的是，为了避免导线缠绕，可旋转组件并非360度旋转的，内部设置有限位结构(如分别在第三伸缩套管和外架接触位置设置个小凸起，转动到一定角度，两个凸起会顶住无法继续转动)，使得转动到一定角度后，限位结构就会限位，避免360度旋转。当然，如果要实现360旋转，只需要在可旋转组件10处加个旋转电接头即可，而后导线中间断开通过旋转电接头连接即可，这样可以实现360转动而不必担心电线缠绕。
可旋转组件10只要能实现二者相互旋转即可，如可以通过转轴和轴套实现。优选的，所述可旋转组件10包括环形凸起100和环形凹槽101，环形凸起100置于所述环形凹槽101内，实现外架6的旋转。
本实用新型不限定环形凸起100和环形凹槽101的设置位置，优选地所述环形凸起100设置于外架顶端，所述环形凹槽101设置于第三伸缩套管4的底端内侧，结构更加紧凑，便于外架6旋转。同时本实用新型不限定伸缩套管的内外套接顺序，可以是第一伸缩套管在最外面，其他伸缩套管依次设置在内部(此为优选实施例)；或者第一伸缩套管在最里面，其他伸缩套管依 次设置在外部。
可转动组件只要能实现偏转即可，如可以是万向球头连接，即外架可以设置成略大于半球的球形凹槽，灯主体为球头，灯主体置于球形凹槽内，即可以实现偏转。在某些实施例中，所述可转动组件9包括转动轴90，所述转动轴90设置于所述外架6中心空腔的两侧，所述灯主体绕所述转动轴90转动，灯主体8设置于转动轴90中间，且灯主体8的顶端与外架6顶端内侧之间有空隙，灯主体8可以进行一定角度的转动，此时配合外架6的旋转，可以实现照射角度的调节，增加了适用性。
优选的，所述外架6的中心空腔两侧相对地设置有支撑条11，所述转动轴90分别设置于支撑条11内侧，用于固定所述灯主体8的位置，所述支撑条11的间距与所述灯主体8尺寸相匹配，所述支撑条11可以塑料，本实用新型的整体的结构材料也可以是塑料。通过支撑条可以实现一定的形变，可以顶住灯主体，使得转动轴置于灯主体内，使得灯主体8与外架6的连接更加稳固，避免在对灯主体8进行转动时可能与外架6分离。
优选的，所述照明单元为LED灯照明单元，使得伸缩灯更加节能。LED单元一般还包括整流模块，整流模块可以设置在灯主体内。
优选的，所述灯主体8的灯罩12为圆形灯罩，使得灯光更均匀的向空间发散，提高照射均匀性，并且增加了灯罩12内部的空间，可有效减缓灯主体8内部的温度上升，延长照明单元的使用寿命。
需要说明的是，尽管在本文中已经对上述各实施例进行了描述，但并非因此限制本实用新型的专利保护范围。因此，基于本实用新型的创新理念，对本文所述实施例进行的变更和修改，或利用本实用新型说明书及附图内容所作的等效结构或等效流程变换，直接或间接地将以上技术方案运用在其他相关的技术领域，均包括在本实用新型专利的保护范围之内。
