技术领域
本申请涉及一种灯具，属于照明技术领域。
背景技术
现有技术中，灯具的散热设计一般是通过减少导热路径或热阻来实现，常表现为填充导热的塑件，但塑件随尺寸变大后，其注塑成型会造成变形，以致增大了导热路径。尤其是在追求节约成本后，其塑件通常使用改性后的PP材质，成型后变形严重，导致整灯散热率低。
有鉴于此，确有必要对现有的灯具进行改进，以解决上述问题。
发明内容
本申请的目的在于提供一种灯具，以提高整个灯具的散热率。
为实现上述目的，本申请提供了一种灯具，包括灯体和设置在所述灯体内的光源组件，所述灯具还包括位于所述灯体和所述光源组件之间的散热结构和紧固件，所述灯体上开设有至少一个穿孔，所述散热结构上朝向所述灯体一侧设有与所述穿孔相对应的盲孔，所述紧固件穿过所述穿孔与所述盲孔相连接，以缩小所述散热结构与所述灯体之间的间隙；所述散热结构上朝向所述光源组件一侧设有连接部，所述连接部与所述光源组件相连接，以缩小所述光源组件与所述散热结构之间的间隙。

作为本申请的进一步改进，所述散热结构包括第一连接板和围设在所述第一连接板四周的第二连接板，所述连接部和所述盲孔均设置在所述第一连接板上，所述第二连接板的外侧壁上设有定位部，所述第一壳体的内侧壁上对应设有配合部，所述定位部和所述配合部相互配合，以使得所述散热结构收容并固定在所述收容腔内。
作为本申请的进一步改进，所述第一壳体包括顶板和与顶板的外周边缘相连的环形侧 板，所述环形侧板的远离所述顶板的一端与所述第二壳体连接，所述穿孔开设在所述顶板上，所述散热结构的第一连接板与所述顶板贴合、所述第二连接板与所述环形侧板贴合。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面结合附图和具体实施例对本申请进行详细描述。
在此，需要说明的是，为了避免因不必要的细节而模糊了本申请，在附图中仅仅示出了与本申请的方案密切相关的结构和/或处理步骤，而省略了与本申请关系不大的其他细节。
另外，还需要说明的是，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。
如图1、图2和图6所示，本申请揭示了一种灯具100，包括灯体10、散热结构20、光源组件30、透光罩40以及用于连接灯体10和散热结构20的紧固件50。光源组件30、散热结构20、灯体10依次组装，最后组装透光罩40。其中，灯体10上开设有至少一个穿孔 11，散热结构20上朝向灯体10一侧设有与穿孔11相对应的盲孔21，紧固件50穿过穿孔11与盲孔21相连接，以固定连接灯体10和散热结构20并缩小散热结构20与灯体10之间的间隙。如此设置，不但能够保证灯具100的安规爬电距离，保持原有灯具100类型的物理隔离，而且还能够对散热结构20做平整度拉伸，避免散热结构20变形，以缩小散热结构20与灯体10、光源组件30之间的连接间隙，从而缩小灯具100内光源组件30至灯体10的散热路径。
结合图2和图3，灯体10包括第一壳体12和围设在第一壳体12外侧的第二壳体13，穿孔11开设在第一壳体12的顶部并贯穿第一壳体12设置。第一壳体12内形成有收容腔14，散热结构20收容在收容腔14内并与第一壳体12的顶部贴合。具体地，第一壳体12包括顶板121和与顶板121的外周边缘相连的环形侧板122，环形侧板122的远离顶板121的一端向外周方向延伸并与第二壳体13连接，如此设置，使得灯体10能够形成双壳体结构，从而可利用第二壳体13来遮挡灯体10与散热结构20的连接结构，使得整个灯具100更加地美观。本实施例中，灯具100为筒灯，第一壳体12和第二壳体13均呈圆柱状设置，但不应以此为限。
本实施例中，穿孔11开设在顶板121上，紧固件50直接穿过顶板121直至与盲孔21相连接，即可固定连接灯体10和散热结构20。此外，透光罩40也收容在收容腔14内。具体地，在第一壳体12的底部、靠近第一壳体12与第二壳体13的连接处设有用于固定透光罩40的连接部17，该连接部17呈环状设置在第一壳体12的内侧壁上，以与透光罩40卡扣固定，使透光罩40固定收容在收容腔14内，不但能够保证光线充分的扩散，而且还能够保护透光罩40，避免损坏。本申请不对透光罩40的具体的类型进行限定，也不对其与灯体10的具体组装方式进行限定，可以采用现有的组装方案，也可以根据实际情况进行适应性调整。
结合图2、图3和图4，散热结构20包括第一连接板24和围设在第一连接板24四周的第二连接板25，第一连接板24呈圆形设置，第二连接板25呈环状设置，以在第一连接板24和第二连接板25之间形成供收容光源组件30的腔体26。散热结构20的第一连接板24与第一壳体12的顶板121贴合、第二连接板25与环形侧板122贴合。具体来讲，盲孔21设置在第一连接板24上，且优选地，第一连接板24上设有朝向光源组件30突伸的凸起23，盲孔21设于该凸起23内。当然，也可在第一连接板24足够厚的前提下直接在第一连接板24上开设盲孔，而不设置凸起，此处不作限制。
本实施例中，紧固件50优选为螺钉，穿孔11优选为螺孔，盲孔21的内壁面上也对应设有螺纹，从而可利用螺钉穿过螺孔并锁紧固定在盲孔21内，来对散热结构20做平整度拉伸并将散热结构20的第一连接板24与灯体10的顶板121紧密贴合，减小散热结构20与灯体10之间的间隙，进而缩短散热结构20与灯体10之间的导热路径。
光源组件30上开设有与凸起23相对应的通孔31，凸起23插入通孔31。具体地，光源 组件30包括光源板33和固定在光源板33上的灯珠34，该通孔31设置在光源板33上，凸起23插入通孔31内，不但能够限位连接光源组件30和散热结构20，还能够使整个灯具100更加的轻薄、更加的轻巧。
散热结构20上还设有朝向光源组件30突伸的连接部22，连接部22与光源组件30直接接触，以进一步缩小光源组件30与散热结构20之间的连接间隙，即散热路径。具体地，该连接部22设置在第一连接板24上，光源板33上开设有与连接部22相对应的连接孔32，连接部22与连接孔32紧密配合。优选地，连接部22穿过连接孔32与光源组件30热熔连接。一方面使得光源组件30与散热结构20能够直接接触，另一方面也能够限制光源组件30与散热结构20随意移动，使得光源组件30与散热结构20之间的连接稳定性较佳。优选地，连接部22为限位柱，且该限位柱22与光源组件30热熔连接。当然，连接部22与光源组件30之间的连接不限于热熔连接，也可以采用超声波焊接、胶粘等方式进行连接，只要能够使连接部22与光源组件30之间连接起来即可，于此不作过多限制。
第二连接板25的外侧壁上设有定位部27，第一壳体12的内侧壁上对应设有配合部15，定位部27和配合部15相互配合，以使得散热结构20收容并固定在收容腔14内。优选地，定位部27为设置在第二连接板25上的卡勾，配合部15为设置在第一壳体12内侧壁上的凸肋。本申请中的散热结构20和灯体10优选为圆形设置，此时配合部15为设置在第一壳体12内侧壁上的环形凸肋，卡勾设置有多个且均匀分布在第二连接板25的外侧壁上。当然，定位部27和配合部15也可以为其他形式的结构，只要能够满足将散热结构20收容并固定在收容腔14内即可，于此不作过多限制。定位部27和配合部15的设置，可以将灯体10和散热结构20先进行预固定，以方便后期利用紧固件50再次固定连接灯体10和散热结构20。
结合图2、图3、图4以及图5，该灯体10上还设有用于线路连接的引线孔16，散热结构20上也设有与引线孔16对应的且呈柱状设置的开孔28，为了线路与光源组件30能够安全连接，在光源板33的边缘处设有凹槽口35。线路依次穿过引线孔16和开孔28，并压入凹槽口35，以使线路与光源组件30电性连接。
为了能够清楚说明该灯具100的结构原理，下面将对该灯具100的组装进行详细说明。本申请中的灯体10优选为具有导热性的金属灯体10，散热结构20优选为绝缘塑件。首先，将光源组件30放入散热结构20的腔体26内，并使得散热结构20上的凸起23和连接部22分别插进光源板33上的通孔31和连接孔32，再将连接部22与光源板33热熔固定连接；然后，将组装有光源组件30的散热结构20放置在灯体10的收容腔14内，并使得散热结构20上的定位部27与灯体10上的配合部15固定连接，以使散热结构20和灯体10卡扣定位；接着，将紧固件50从灯体10上的穿孔11穿入直至与盲孔21相连接，将紧固件50锁紧，使散热结构20和灯体10锁紧固定；最后，将透光罩40与灯体10组装固定，此时即完成了灯具100的组装。
光源组件30上的灯珠34产生的光能转化成热量后，整个灯具100的散热路径为：热量从灯珠34传至光源板33，再由光源板33传至散热结构20，再由散热结构20传至灯体10，最后由灯体10将热量传出灯具100外部。本申请通过缩小散热结构20与灯体10之间、散热结构20与光源板33之间的间隙，从而提高了整个灯具100的散热效率。
综上所述，本申请的灯具100通过在灯体10上开设穿孔11，同时在散热结构20上设置与穿孔11相对应的盲孔21，从而可通过紧固件50穿过穿孔11并与盲孔21相连接，来对散热结构20做平整度拉伸，以缩短散热结构20与灯体10、光源组件30之间的散热路径，使得整个灯具100的散热率得以提高，延长了灯具100的使用寿命。
以上实施例仅用以说明本申请的技术方案而非限制，尽管参照较佳实施例对本申请进行了详细说明，本领域的普通技术人员应当理解，可以对本申请的技术方案进行修改或者等同替换，而不脱离本申请技术方案的精神和范围。
