本发明采用的技术方案能够达到以下有益效果：
本发明公开的灯具中，当光源模组通过穿孔伸出至第一内腔之外的过程 中，光源模组的发光区域的面积增大，从而使得灯具的照射范围增大，灯具的亮度增大；当光源模组通过穿孔回缩至第一内腔中时，光源模组的发光区域的面积减小，从而使得灯具的照射范围减小，灯具的亮度减小；此时，通过调节光源模组在第一内腔的位置，从而可以对光源模组的照射范围以及亮度进行调节，因此能够满足用户在不同场景下的应用，增加了灯具的应用场景，进而提高了灯具的使用效率。
另外，第一壳体与支撑杆组件磁吸连接，从而使得第一壳体可以与支撑杆组件相分离，进而使得灯具占用的收纳空间较小，从而方便灯具收纳。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合本发明具体实施例及相应的附图对本发明技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
以下结合附图，详细说明本发明各个实施例公开的技术方案。
如图1～图6所示，本发明实施例公开一种灯具，该灯具可以包括灯头100、灯座200以及支撑杆组件300。
灯头100包括第一壳体110和光源模组120，第一壳体110具有内腔和与内腔连通的穿孔，光源模组120可移动地设置于内腔，至少部分光源模组120可通过穿孔伸出至内腔之外或回缩至内腔中。可选的，用户可以对光源模组120施加作用力，从而驱动光源模组120移动，或者第一内腔还可以设置驱动机构，驱动机构与光源模组120连接，以驱动光源模组120移动，该驱动机构可以是直线电机、气缸等驱动部件。
第一壳体110通过支撑杆组件300支撑于灯座200，灯座200用于安装灯头100和支撑杆组件300。第一壳体110与支撑杆组件300可拆卸相连，第一壳体110和支撑杆组件300中，一者设置有第一磁性件，另一者设置有磁吸件，第一磁性件与磁吸件磁性相吸，从而实现第一壳体110与支撑杆组件300之间的装配。第一磁性件与磁吸件之间的磁吸力应确保第一壳体110与支撑杆组件300磁吸配合后，第一壳体110能够实现位置的保持。可选的，第一磁性件可以是电磁铁，也可以是永磁铁。对于第一磁性件的具体结构本文不作限制。
本发明实施例中，当光源模组120通过穿孔伸出至内腔之外的过程中，光源模组120的发光区域的面积增大，从而使得灯具的照射范围增大，灯具的亮度增大；当光源模组120通过穿孔回缩至内腔中时，光源模组120的发光区域的面积减小，从而使得灯具的照射范围减小，灯具的亮度减小；此时，通过调节光源模组120在内腔的位置，从而可以对光源模组120的照射范围以及亮度进行调节，因此能够满足用户在不同场景下的应用，增加了灯具的应用场景，进而提高了灯具的使用效率。
同时，第一壳体110与支撑杆组件300磁吸连接，从而使得第一壳体110可以与支撑杆组件300相分离，进而使得灯具占用的收纳空间较小，方便灯具收纳。
另外，灯具未使用时，可以将光源模组120全部设置于内腔中，从而防止光源模组120的损坏。
可选的，第一壳体110可以采用透光率较低的材料制作，当光源模组120全部位于内腔中时，灯具的亮度较低，此时，灯具可以用于照明条件要求较低的模式(例如夜灯模式)，因此增加了灯具的使用场景，进一步提高了灯具的使用效率。
一种可选的实施例中，第一壳体110与支撑杆组件300中，一者设置有球形凸起410，另一者设置有球形凹槽420，球形凸起410与球形凹槽420中，一者为第一磁性件，另一者设置为磁吸件，在第一壳体110与支撑杆组件300相连接的情况下，第一磁性件与磁吸件磁性相吸。此时，第一壳体110与支撑杆组件300之间球面配合，使得第一壳体110绕着支撑杆组件300转动，同时，还可以对第一壳体110与支撑杆组件300之间的角度进行调节，进而可以对光源模组120进行多方位、多角度的调节，从而满足了用户在不同场景下的应用，因此进一步提高了灯具的使用效率。
可选的，球形凸起410可以设置于第一壳体110上，球形凹槽420可以设置于支撑杆组件300上。或者，球形凸起410可以设置于支撑杆组件300 上，球形凹槽420可以设置于第一壳体110上。球形凸起410可以为第一磁性件，球形凹槽420可以为磁吸件，或者球形凸起410可以为磁吸件，球形凹槽420可以为第一磁性件。
具体地，磁吸件可以为铁质件，铁质件加工简单、方便，从而使得灯具的制造成本较低。为了使得第一磁性件和磁吸件具有较大的磁吸力，另一种实施例中，磁吸件还可以为第二磁性件，第二磁性件与第一磁性件磁性相反。此时，磁吸件也是磁性结构，第一磁性件和磁吸件磁性配合时，第一磁性件和磁吸件的磁吸力较大，第一壳体110和支撑杆组件300连接的更加紧固，从而提高了灯具的安全性和可靠性。可选的，第二磁性件可以为电磁铁，也可以为永磁铁。
上述实施例中，第一磁性件和磁吸件在转动或者拆卸的过程中，可能会对第一磁性件和磁吸件的表面造成磨损，进而可能致使第一磁性件和磁吸件磁吸配合不紧密，从而使得第一磁性件和磁吸件的磁吸力减小，进而可能造成第一壳体110从支撑杆组件300上掉落，因此降低了灯具的安全性和可靠性。为此，第一磁性件或者磁吸件的表面设置有镀层。此方案能够防止第一磁性件和磁吸件的表面发生磨损，从而使得第一磁性件和磁吸件实现磁吸紧密配合，第一壳体110不容易从支撑杆组件300上掉落，进而提高了灯具的安全性和可靠性。
为了进一步缓解第一磁性件和磁吸件之间的磨损，另一实施例中，第一磁性件和磁吸件的表面均设置有镀层。此方案进一步缓解了第一磁性件和磁吸件之间的磨损，因此进一步提高了灯具的安全性和可靠性。可选的，该镀层可以采用钴、镍等材料制作。
上述实施例中，支撑杆组件300可以设置导轨，第一壳体110与导轨滑动连接，从而能够调节灯头100的高度。此种方案需要在支撑杆组件300的内部设置导轨，使得支撑杆组件300的制造工艺复杂，造成灯具的制造成本增加。同时，支撑杆组件300内部设置导轨，致使支撑杆组件300的体积增 大，从而使得灯具的外观尺寸较大，不便于携带和收纳。一种可选的实施例中，支撑杆组件300可以包括至少两个支撑杆，任意相邻的两个支撑杆中，一者滑动地套设于另一者内，此时，用户可以驱动其中至少一个支撑杆，从而带动第一壳体110移动，进而可以调节灯头100的高度。位于支撑杆的一端的支撑杆设置有第一磁性件或磁吸件，位于支撑杆的另一端的支撑杆与灯座200相连接。此时，相邻的两个支撑杆相套接，使得支撑杆组件300的制造工艺简单，从而使得灯具的制造成本较低。同时，支撑杆的内部不需要预留安装空间，因此支撑杆组件300的外观尺寸较小，从而使得灯具的外观尺寸较小，进而使得灯具方便携带和收纳。可选的，支撑杆可以为圆杆，圆杆外壁光滑，视觉感更优，因此使得灯具的外观质感更优。相邻两个支撑杆之间紧配合，从而使得至少一个支撑杆在移动到指定位置时，可以保持在指定位置。
当任意一个支撑杆在滑动时，该支撑杆超过滑动的行程时，相邻两个套装的支撑杆相分离，从而造成灯具损坏，进而使得灯具的安全性和可靠性较低。一种可选的实施例中，支撑杆可以设置有第三限位部，在支撑杆的移动方向上，任意相邻的第三限位部限位配合。此时，任意相邻的两个第三限位部能够防止支撑杆的行程超出可滑动的范围，从而防止相邻两个支撑杆分离，进而提高了灯具的安全性和可靠性。可选的，第三限位部可以为第一凸起，当支撑杆滑动到最大行程时，相邻的两个第一凸起限位配合，从而防止相邻的两个支撑杆相分离。
一种可选的实施例中，灯座200与支撑杆组件300可拆卸连接，此时，支撑杆组件300可以从灯座200上拆卸下来，从而使得灯具方便收纳。可选的，灯座200与支撑杆组件300可以采用磁吸、卡接或者螺纹连接。
灯座200与支撑杆组件300采用磁吸连接时，当灯座200与支撑杆组件300之间的磁吸力较小时，支撑杆组件300容易从灯座200上脱落；当灯座200与支撑杆组件300之间的磁吸力较大时，支撑杆组件300与灯座200拆 卸不方便；因此，灯座200与支撑杆组件300中用于磁吸的磁性件的加工精度较高，从而使得灯具的制造成本较高。灯座200与支撑杆组件300还可以采用卡接，然而，灯座200与支撑组件多次拆卸后较容易造成卡勾断裂，从而使得灯具的可靠性较低。灯座200与支撑杆组件300还可以采用螺纹连接，此种方式需要在支撑杆组件300或者灯座200上开设螺纹孔，螺纹孔设置于灯具的外观面上，造成灯具的外观质感较差，从而使得用户体验较差。
为此，另一种实施例中，灯座200和支撑杆组件300中，一者可以设置有连接凸起510，另一者可以设置有连接凹槽，连接凸起510与连接凹槽插接配合。此时，连接凸起510插入连接凹槽中，连接凸起510与连接凹槽的加工精度要求较低，从而降低了灯具的制造成本。同时，连接凸起510与连接凹槽在插拔的过程中没有力的作用，因此不会造成连接凸起510或者连接凹槽的损坏，因此灯具的可靠性较高。另外，连接凸起510位于连接凹槽内，连接凸起510与连接凹槽不会外露，因此灯具的外观质感较好，从而改善了用户体验。
上述实施例中，为了使连接凸起510能够顺利的插入连接凹槽内，连接凸起510的尺寸可以小于连接凹槽的尺寸，但是这就使得连接凸起510与连接凹槽之间存在间隙，从而使得支撑杆组件300可相对于灯座200转动。为此，一种可选的实施例中，灯座200或支撑杆组件300还可以设置有防旋转凸起520，防旋转凸起520与连接凸起510间隔设置，防旋转凸起520与连接凹槽插接配合。此时，防旋转凸起520能够防止连接凸起510在连接凹槽内转动，进而防止支撑杆组件300相对于灯座200转动。
一种可选的实施例中，第一壳体110可以为条形结构，光源模组120也可以为条形结构，光源模组120沿第一壳体110的延伸方向移动。此时，光源模组120的移动行程较长，从而使得光源模组120的亮度的可调节范围大，从而进一步提高灯具的使用效率。
上述实施例中，光源模组120上设置有线路结构和电子元器件，当光源 模组120直接设置于第一壳体110内时，光源模组120在移动的过程中，线路结构和电子元器件容易与第一壳体110的内壁相碰撞，从而造成线路结构与电子元器件磨损。为此，一种可选的实施例中，上述灯头100还可以包括第二壳体130，至少部分第二壳体130可通过穿孔伸出至内腔之外或回缩至内腔中，光源模组120设置于第二壳体130上。此时，仅光源模组120的出光面外露，光源模组120的线路结构和电子元器件均隐藏于第二壳体130中，从而使得光源模组120在移动时，线路结构和电子元器件不会与第一壳体110的内壁发生碰撞，从而不会造成线路结构和电子元器件的磨损，进而提高了灯具的安全性和可靠性。
第二壳体130相对于第一壳移动，当第二壳体130超出移动的行程时，第二壳体130与第一壳体110可能会分离，进而降低了灯具的安全性和可靠性。为此，第一壳体110可以设置有第一限位部，第二壳体130可以设置有第二限位部，在第二壳体130的移动方向上，第一限位部与第二限位部限位配合。此时，第一限位部和第二限位部能够防止第二壳体130的行程超出可调节的范围，进而提高了灯具的安全性和可靠性。可选的，第一壳体110上可以设置第二凸起，第二壳体130上可以开设限位凹槽，该第二凸起设置于限位凹槽内，限位凹槽的长度与第二壳体130的移动距离相等。
一种可选的实施例中，本发明公开的灯具还可以包括第一传感器，第一传感器设置于第一壳体110的靠近支撑杆组件300的一端，穿孔设置在第一壳体110的另一端，第一传感器用于检测其与光源模组120之间的位置数据。可选的，第一传感器检测到的数据可以是其与光源模组120之间的距离数据，也可以是其与光源模组120之间的作用力数据，因此第一传感器可以是距离传感器，也可以是力传感器。
当第一传感器为距离传感器时，在光源模组120通过穿孔伸出至内腔之外的过程中，光源模组120与第一传感器之间的距离逐渐增大，光源模组120的伸出量越大，功率越大，光源模组120的亮度越大；在光源模组120通过 穿孔缩回至内腔之内的过程中，光源模组120与第一传感器的距离逐渐减小，光源模组120的伸出量越小，功率越小，光源模组120的亮度越小；此时第一传感器将检测到的距离数据传输到灯具的控制器，该控制器与灯具的电源电连接，从而控制电源调节灯具的功率。第一传感器和光源模组120之间的距离与光源模组120的功率成正比。
此时，光源模组120伸出或者回缩的过程中，光源模组120的功率也随之变化，因此可根据光源模组120的伸出量调节光源模组120的功率，进而使得灯具的节能性更好。同时，通过调节光源模组120的功率，进而控制光源模组120的亮度，使得灯具的亮度既能够满足用户的照明需求，又减少对用户眼部的伤害。
当第一传感器为力传感器时，第一传感器与光源模组120具有受压和受拉两种情况，当第一传感器与光源模组120受压时，在光源模组120通过穿孔伸出至内腔之外的过程中，光源模组120与第一传感器之间的压力逐渐减小，光源模组120与第一传感器之间的压力越小，光源模组120的功率越大，光源模组120的亮度越大；在光源模组120通过穿孔缩回至内腔之内的过程中，光源模组120与第一传感器的压力逐渐增大，光源模组120与第一传感器之间的压力越大，光源模组120的功率越小，光源模组120的亮度越小。
当第一传感器与光源模组120受拉时，在光源模组120通过穿孔伸出至内腔之外的过程中，光源模组120与第一传感器之间的拉力逐渐增大，光源模组120与第一传感器之间的拉力越大，光源模组120的功率越大，光源模组120的亮度越大；在光源模组120通过穿孔缩回至内腔之内的过程中，光源模组120与第一传感器的拉力逐渐减小，光源模组120与第一传感器之间的拉力越小，光源模组120功率越小，光源模组120的亮度越小。
此时第一传感器将检测到的作用力数据传输到灯具的控制器，该控制器与灯具的电源电连接，从而控制电源调节灯具的功率。
可选的，光源模组120与第一传感器的距离数据或者作用力数据在递增 或者递减的过程中，可以是无极调节，也可以是小梯度的递增或者递减，而相对应的光源模组120的功率可以是无极调节，也可以是小梯度的递增或者递减。
另一种实施例中，光源模组120包括在其移动方向依次分布的多个发光区域，其中：被第一壳体110遮盖的发光区域与外露于第一壳体110的发光区域分别被控制。此时，灯具上可以设置有第二传感器，第二传感器用于检测光源模组120被第一壳体110遮盖的发光区域的面积，或者外露于第一壳体110的发光区域的面积，从而将检测到的数据传输到控制器，此时，控制器可以对光源模组120进行调节，从而使得外露于第一壳体110的发光区域的亮度大于被第一壳体110遮盖的发光区域的亮度，或者关闭被第一壳体110遮盖的发光区域。此时，有效降低了光源模组120的电能损耗，进一步改善了灯具的节能性能。
在光源模组120通过穿孔伸出至内腔之外的过程中，外露于第一壳体110的发光区域的面积逐渐增大，使得外露于第一壳体110的发光区域的亮度逐渐增大。
在光源模组120通过穿孔缩回至内腔之内的过程中，外露于第一壳体110的发光区域的面积逐渐减小，使得外露于第一壳体110的发光区域的亮度逐渐减小。
上述实施例中，本发明公开的灯具还可以包括控制开关600，其用于控制光源模组120的开启或关闭。该控制开关600可以设置于第一壳体110的侧壁上，然而，当用户拆卸灯头100时，需要用手握持第一壳体110的侧壁，这就容易使用户触碰到控制开关600，从而容易造成用户的误操作。一种可选的实施例中，控制开关600可以设置于第一壳体110背离支撑柱组件300的一端。此时，用户握持第一壳体110时不容易触碰到控制开关600，从而不容易造成用户的误操作。可选的，该控制开关600可以是按压式开关，也可以是触摸式开关，该控制开关600还可以设置有多个控制档位，从而可以 调节光源模组120的亮度。
一种可选的实施例中，灯头100可以设置有电池仓，电池仓设置有电池，该电池与光源模组120电连接。或者，灯头100设置有电连接插头，电连接插头与光源模组120电连接。此时，灯具的供电部件设置于灯头100上，当灯头100与支撑杆组件300分离后，灯头100依然可以独立工作，从而提升了灯具的灵活性。
本发明实施例公开的灯具可以为台灯或落地灯。当然该灯具也可以是其他种类的照明设备，本发明实施例对此不做限制。
本发明上文实施例中重点描述的是各个实施例之间的不同，各个实施例之间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
以上所述仅为本发明的实施例而已，并不用于限制本发明。对于本领域技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
