具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
以下结合附图，详细说明本申请各实施例提供的技术方案。
本申请实施例公开了一种柱形灯具1，如图1所示。柱形灯具1包括灯 体10，灯体10具有轴线b，灯体10具有两端，所述两端被轴线b贯穿；为便于放置灯体10，柱形灯具1可以包括底座16，灯体1放置在底座16上；如图1所示；为提高散热性能，底座16和顶盖18可以分别或全部由金属制成。
为提高柱形灯具1密闭性，柱形灯具1可以包括顶盖18，顶盖18覆盖灯体10两端中的一端，在一种实施例中，顶盖18可以通过卡榫结构卡接在灯体10的一端，图6为采用一种卡榫结构的顶盖18沿轴线b的剖面图，顶盖18可以通过卡勾182卡接在灯体10的上端，被覆盖的灯体10的一端设置有卡接结构，卡接结构上设置有配合卡勾182的卡口，所述卡接结构和卡口可以是多种样式，此处不再举例；顶盖18还可以采用其他形式覆盖在灯体10的一端，如燕尾榫等，此处不再赘述。
柱形灯具1还包括多个光源模组12和与光源模组12配套的扩散透镜14，如图2所示。多个光源模组12环绕轴线b设置在灯体10上，光源模组12包括发光单元120和光源板122,发光单元120设置在光源板122背离灯体10的一侧，每个扩散透镜14覆盖一个光源模组12，双曲面透镜14包含背离灯体10轴线的外表面140和朝向轴线b的内表面142，内表面142向远离灯体10的方向凹陷形成空腔144，空腔144的延伸方向与轴线b一致，发光单元120设置在空腔144内。
本实施例采用多个扩散透镜相互配合，将与扩散透镜所对应的光源板出射光线进行发散，因此相邻扩散透镜发散后的出射光线会相互干涉，从而可以360°向外周发射光线，实现360°发光，无出光暗区的技术效果。
本实施例所述扩散透镜，是指出射光线发散程度较入射光线高的透镜，可以是双曲面透镜，如凹凸透镜，也可以是平凹透镜，此处不再赘述。
在本实施例中，光源模组12和扩散透镜14垂直于轴线b的截面可以设置为轴对称结构，从而使出光光路也为轴对称结构，进而提升柱形灯具1的出光均匀性。
在本实施例中，灯体10上可以设置有多个光源板插槽102，多个光源板插槽102环绕轴线b设置且延伸方向与轴线b一致，光源板122插置在光源板插槽102内，通过使用插置的形式将光源板固定在灯体上，在保证结构稳定性的前提下，便于拆卸和维修。
为提高散热效率和灯体结构强度，灯体10可以由金属材质制作而成，此外光源板插槽102可以设置为开口方向背离轴线b的U型槽，增大光源板与灯体10相接触部分的面积，从而可以提高散热效率。
在本实施例中，灯体10上还可以设置有多个透镜插槽104，多个透镜插槽104环绕轴线b设置且延伸方向与轴线b一致，扩散透镜14插置在透镜插槽104内，通过使用插置的形式将扩散透镜14固定在灯体10上，在保证结构稳定性的前提下，便于拆卸和维修。
当采用插置的形式固定扩散透镜14时，为使发光区域内的光线均由外表面140出射，不存在其他位置出射的杂光干扰，进而实现较好的照明效果，在灯体10上设置有多个遮挡部106，如图5所示，每个透镜插槽104背离轴线b的一侧均具有出光槽口108，每个出光槽口108的两侧均具有遮挡部106，遮挡部106由出光槽口108延伸至覆盖外表面140的边缘，由于除了外表面140外其余可能出光的区域均被遮挡部106及透镜插槽104遮挡，从而实现了出射光线全部由外表面的限制区域内出射，不存在其他位置出射的杂光干扰的技术效果。
遮挡部106可以与透镜插槽104集成设置，同时遮挡部106限制扩散透镜14由背离轴线b的方向脱离，从而进一步固定扩散透镜。
如图4所示，设置在相邻两个透镜插槽104的临接侧的两个遮挡部106可以集成为一体，增大散热面积，提高散热效率。
在一种实施例中，每个扩散透镜14包含一对相对且延伸方向与轴线b一致的侧表面146，内表面142通过侧表面146与外表面140相连。为增强扩散透镜14与灯体10的固着程度，侧表面146设置有一个第一卡接部1460， 如图3所示，图3为图2中区域A的放大图，同时透镜插槽104包含一对延伸方向与轴线b一致的侧壁1040，侧壁1040上设置有与第一卡接部1460相互配合的第二卡接部1042，通过第一卡接部1460与第二卡接部1042的相互配合将扩散透镜固定在灯体10上，使用这种方式限制扩散透镜14由背离轴线b的方向脱离，为扩散透镜固定方式提供了更多的选择，此处仅描述了一个第一卡接部与一个第二卡接部通过形状配合进行固定的实施例，实际应用中可使用任意个第一卡接部与第二卡接部，此处不再赘述。
为增强灯体机械强度，如图3所示，可以将相邻两个透镜插槽104的临接侧集成在一起构成一个完整的临接部1044，临接部1044背离轴线b的外侧面1046与相邻的两个扩散透镜外表面140平滑过渡，如图4所示，通过此处平滑过渡，可以使外侧面1046和外表面140相邻接的边缘相互平齐，在忽略临接部分产生的缝隙的情况下，外侧面1046和外表面140能够拼接成一个规整的外轮廓，从而使灯体1垂直于轴线b的截面外轮廓线形成诸如圆形、椭圆形、圆角四边形、圆角六边形、圆角八边形等规整形状，如图2所示，即为灯体1垂直于轴线b的截面外轮廓线为圆形的情况，此处不再对外轮廓线为其他形状的情况进行赘述。
为增强柱形灯具使用方便性，如图1所示，可以在底座16上设置电插头162，电插头162用于为光源模组12供电，电插头162可以插置于插座上取电，电插头162的造型可以设置为E14、E27、G10等，如图1所示为设置为G10形式的电插头162。
本申请实施例的有益效果是：本申请采用多个扩散透镜，将与透镜所对应的光源板出射光线进行发散，因此相邻扩散透镜发散后的出射光线会相互干涉，消除原本由于光源板接缝处无光源而产生的暗区，实现360°发光，整体无暗区，发光效果好。
综上所述，本申请实施例所提供的柱形灯具能够实现无出光暗区的技术效果。
本申请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。
以上所述仅为本申请的实施例而已，并不用于限制本申请。对于本领域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
