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5所示，本发明实施例公开一种灯具，其包括灯体、光源模组200、导电部220、固线盖300和散热部400。
其中，灯体为灯具的主体结构，灯体设有接线孔，以保证灯具能够外接电源进行照明工作，接线孔的尺寸可以根据线缆等导电部件的尺寸设计，此处不作限定。灯体可以采用塑料或金属等材料制成，灯体可以仅作为灯具中其他部件的安装结构，如其可以仅为安装座，可以借助螺钉、卡扣或胶水等将灯体安装在安装基础上；或者，灯体也可以作为提供配光作用的部件，在这种情况下，灯体可以为透光材料制成的。
光源模组200包括光源基板和发光体210，光源基板安装于灯体之内，发光体设置于光源基板，发光体210可以为LED灯珠或LED贴片。光源基板可以为发光体210供电，保证发光体210能够正常工作。发光体210的数量可以为一个，也可以为多个，多个发光体210可以呈阵列式排布，或者，也可以呈圆环式排布。
导电部220与光源基板电性连接，且为发光体210供电，导电部220自接线孔伸出至灯体之外。导电部220可以为漆包线，更具体地，导电部220可以为铜金属线，以减轻导电部220的发热情况。导电部220可以通过焊接 或缠绕等方式与光源基板形成可靠的电连接关系。
固线盖300上设置有穿线孔，固线盖300可以采用塑料或石棉等材料制成，穿线孔的大小可以根据导电部220的尺寸确定，导电部220位于穿线孔内，固线盖300能够为导电部220提供一定的限位作用，防止导电部220因大幅动作而与光源基板断开连接。
散热部400与灯体配接并连接于灯体中接线孔所在的一侧，散热部400可以为灯体提供散热作用，提升灯具的整体散热效果。散热部400包括多个散热片410，多个散热片410间隔地环绕固线盖300设置，使得多个散热片410之间能够与气体进行热交换，提高各散热片410与气体进行热交换的面积，进一步提升灯具的整体散热效率。
固线盖300与散热部400配接，散热部400能够为固线盖300提供固定基础，可选地，固线盖300采用粘接或螺纹连接等方式与散热部400连接，优选地，固线盖300采用可拆卸连接方式与散热部400相互固定，这便于灯具后期维护工作的进行。为了进一步提升散热部400散热效率，至少一个散热片410向背离灯体的方向延伸至超出固线盖300。在这种情况下，气体能够不受灯体和固线盖等部件的阻碍，在自灯具的一侧经该散热片的表面流动至灯具的另一侧，增强了灯具的中心区域的对流强度，增加了灯具的有效自然对流面积，从而进一步提升灯具的散热效果，保证灯具具有较高的使用寿命。
进一步地，可以使多个散热片410平齐设置，且均向背离灯体的方向延伸至超出固线盖300。在这种情况下，各散热片410表面的气体流速及自然对流强度均可以得到提升，从而进一步提升灯具的整体散热效率，并且，采用上述技术方案的情况下，可以使灯具中各位置处的散热效率相对均匀，防止灯具存在局部散热困难的情况，进一步提升灯具的使用寿命。
可选地，在接线孔的轴向上，散热片410背离灯体的端部与固线盖300之间的间距为7mm～9mm。在这种情况下，散热片410的散热效果相对较好， 且不会造成灯具的整体尺寸扩大过多，另外，还可以保证固线盖300具有满足需求的安装和拆装空间。
进一步地，固线盖300与灯体间隔设置，固线盖300、灯体和散热部400围成接线空间。在固线盖300与灯体之间具有一定的间隔的情况下，便于导电部220与光源基板之间连接过程的进行，且可以为导电部220和光源基板的接头提供一定的容纳空间。
为了进一步防止导电部220与光源基板发生相对移动，可选地，灯具还包括防拉线扣500，导电部220与防拉线扣500相对固定，且防拉线扣500设置于穿线孔，从而进一步限制导电部220的位置，保证导电部220与光源基板之间的相对位置基本不会发生变化。防拉线扣500的部分位于接线空间之内，防拉线扣500的外壁设有限位槽510，固线盖300伸入限位槽510，固线盖300与防拉线扣500在接线孔的轴向限位配合。在固线盖300与散热部400相对固定的情况下，防拉线扣500也可以与灯体形成相对固定关系。限位槽510可以为环状结构，也就是说，防拉线扣500的外周环绕设置有限位槽510，相应地，固线盖300的内侧边缘均可以伸入至限位槽510中，这可以进一步提升固线盖300与防拉线扣500之间限位配合关系的稳定性。
可选地，固线盖300采用卡接的方式与散热部400连接，进一步地，散热片410设有卡持缺口411，固线盖300设有弹性卡扣310，弹性卡扣310伸入卡持缺口411，固线盖300与散热片410在接线孔的轴向限位配合。具体地，弹性卡扣310和固线盖300可以由塑料采用一体注塑的方式形成，这使得固线盖300与弹性卡扣310之间的连接可靠性更高，保证固线盖300与散热部400之间的固定效果更稳定。
进一步地，卡持缺口411和弹性卡扣310的数量均可以为多个，多个弹性卡扣310沿接线孔的周向间隔排布，多个卡持缺口411和多个弹性卡扣310一一对应配合。在这种情况下，可以进一步提升固线盖300与散热部400之间连接关系的稳定性和可靠性。弹性卡扣310的数量具体可以为三个或四个， 多个弹性卡扣310可以沿接线孔的周向均匀布置，从而保证固线盖300与散热部400之间各处的连接可靠性均较好。
更具体地，弹性卡扣310可以为矩形块状结构，相似地，卡持缺口411也为矩形缺口，通过使弹性卡扣310伸入至卡持缺口411中，可以防止固线盖300继续向散热部400之内伸入，也可以防止固线盖300脱离散热部400。
或者，弹性卡扣310可以为端部设有避让结构的卡扣，在这种情况下，弹性卡扣310可以沿散热部400的内侧边缘运动，直至弹性卡扣310越过卡持缺口411的边缘，伸入至卡持缺口411内且与卡持缺口411相互配合，这种结构形式的弹性卡扣310能够限制固线盖300脱离散热部400。为了使弹性卡扣310能够保持于卡持缺口411处，可以使固线盖300与散热部400中形成卡持缺口411的部分产生限位关系，防止在弹性卡扣310伸入至卡持缺口411内之后，固线盖300仍能够继续向散热部400之内伸入。
更具体地，散热片410上与卡持缺口411背离接线孔的一侧设有弧形导向块412，在组装固线盖300和散热部400的过程中，弧形导向块412可以为固线盖300提供一定的导向作用，在固线盖300与弧形导向块412相互配合的情况下，弧形导向块412能够促进固线盖300继续向散热部400之内伸入，直至弹性卡扣310伸入至卡持缺口411内。并且，在上述情况下，固线盖300还可以在垂直于接线孔的轴向的方向与弧形导向块412形成限位关系，进一步提升固线盖300与散热部400之间的限位关系。可选地，散热片410背离灯体的一端的角部设有倒圆角结构413，这可以提升灯具的安全性能，防止散热片410刺伤用户。
可选地，在接线孔的轴向上，散热片410靠近接线孔的端部的宽度为第一宽度，散热片410背离接线孔的端部的宽度为第二宽度，且可以使第一宽度大于第二宽度。在这种情况下，一方面可以减小散热部400的整体尺寸；另一方面，在灯体的热量传递至散热部400上之后，散热部400靠近灯体的一端的外周的温度相对较高，其周围的气体的温度也相对较高，由于散热部 400背离灯体的一端的外周位于散热部400靠近灯体的一端的外周之内，因而散热部400靠近灯体的一端的周围的温度更容易向远离灯体的方向流动，从而便于散热部400上热量散发过程的进行，提升散热部400的散热效率。
本发明实施例公开的灯具具体可以为射灯，其可以安装在屋顶或天花板上。进一步地，灯体包括反射器100和灯环610，灯环610作为灯具的安装结构，其可以为环状结构，且灯环610的相背两端均可以为开放式结构，灯环610的一端作为出光端，灯环610的另一端作为接线端，且灯环610中背离出光端的一端可以作为散热部400的安装端。灯环610具有光源腔611，反射器100安装于光源腔611内。可选地，反射器100可以通过螺钉等部件固定在灯环610上，或者，反射器100还可以通过粘接固定在灯环610上。反射器100设有接线孔，光源基板安装于反射器100之内，相似地，光源基板也可以通过粘接、卡接或螺纹连接等方式与反射器100相互固定，保证反射器100能够为安装在光源基板上的发光体210提供稳定的反射聚光作用；另外，与光源基板连接的导电部220可以通过反射器100上的接线孔穿出至反射器100之外，以外接电源。
更具体地，灯环可以采用金属等硬质材料制成，以保证灯具具有较长的使用寿命。灯环可以采用螺钉连接件固定在屋顶或天花板上，或者，灯环610还可以采用卡接等方式安装在屋顶或天花板上。反射器100可以由塑料制成，反射器100可以为扩口状结构，其内侧可以涂覆有反光材料。
进一步地，灯环610与散热部400通过密封垫620密封配合，以提升二者之间的连接气密性。灯环610和散热部400可以通过螺栓组件相互连接，这可以保证二者之间能够形成可靠地固定连接关系。密封垫620可以采用橡胶材料制成，其厚度可以根据实际情况选定，借助螺栓组件的锁紧作用，可以保证灯环610和散热部400能够形成可靠的密封配合关系。另外，灯环610还可以设置有环状限位结构，散热部400设置在环状限位结构的内侧，一方面使灯环610和散热部400能够形成预定位作用，另一方面还可以使灯环610 和散热部400之间的配合关系更稳定。
进一步地，灯环610的内侧可以设置有台阶支撑部612，反射器100可以支撑在台阶支撑部612上，降低反射器100和灯环610的连接难度。反射器100背离接线孔的一侧设有匀光面罩630，匀光面罩630可以为发光体210提供导光作用，以进一步提升灯具的光照效果；并且，匀光面罩630还可以提升灯具的密封性能，防止外界的水汽和灰尘等杂质进入灯体之内。在设置有匀光面罩630的情况下，反射器100可以支撑在匀光面罩630上，匀光面罩630可以支撑在台阶支撑部612上，从而完成上述部件的组装工作。
具体地，匀光面罩630可以采用塑料等透光材料制成，在灯环610为圆形结构的情况下，匀光面罩630也可以为圆形结构件。匀光面罩630和反射器100依次支撑在台阶支撑部612上，在散热部400安装于灯环610另一侧的情况下，匀光面罩630和反射器100能够被夹持固定在灯环610和散热部400之间。当然，也可以通过粘接的方式使匀光面罩630和反射器100直接固定在台阶支撑部612上。
为了进一步提升灯具的密封性能，可选地，匀光面罩630的外周套设有密封圈640，反射器100通过密封圈640与台阶支撑部612密封配合，在密封圈640套设于匀光面罩630上的情况下，既可以保证匀光面罩630与反射器100之间能够形成较高的密封效果，还可以保证匀光面罩630与台阶支撑部612能够形成可靠的密封关系。密封圈640可以采用橡胶或泡棉等材料制成，在散热部400与灯环610相互连接之后，通过对密封圈640产生一定的挤压作用，可以进一步保证密封圈640能够为灯环610提供较为可靠的密封连接关系。
进一步地，灯具包括外环650和弹簧扣660，外环650连接于灯环610之外，外环650可以作为灯环610的防护结构，外环650可以通过螺钉等连接件固定在灯环610上，外环650也可以为圆环状结构，其外周设有弹簧扣660，在灯具被设置于天花板上的安装孔之内的情况下，弹簧扣660可以通过 弹性卡接的方式使灯具保持固定状态，实现灯具的安装目的。当然，为了保证灯具的固定情况较为稳定，弹簧扣660的数量为至少两个，且两个弹簧扣660相对设置，以为灯具提供稳定的弹性支撑力，使灯具能够稳定地被固定在天花板上。
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。
