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。
请参考图7，本发明公开一种灯具，这里的灯具可以是灵显导轨射灯、皓平台射灯、调色温射灯等任意一种，具体来说灯具可以包括电器盒组件100、罩壳200、透镜600、限位环700和光源组件。罩壳200具有相对设置的第一壳体口和第二壳体口，电器盒组件100设于第一壳体口，比如电器盒组件100处于罩壳200外、并对第一壳体口进行封堵设置。光源组件和透镜600可以均设于罩壳200内。
其中，光源组件可以包括光源件300和光源支架500。光源件300为光源组件的发光体，其结构可以是常见的COB光源、LED光源等。光源支架500可以为光源组件的相关部件提供承载基础，比如通过注塑等工艺制作生成的支撑架等。光源组件可以通过光源支架500连接罩壳200，具体来说可以在光源支架500的周部设置卡槽，而在罩壳200的内周壁设置卡条，以使光源支架500和罩壳200相互卡接。这样罩壳200可以对光源组件和透镜600提供遮罩保护。限位环700穿设于第二壳体口，以将光源组件和透镜600约束固定在罩壳200中。
光源组件、透镜600和限位环700沿远离第一壳体口的方向依次设置，同时光源件300的发光侧朝向第二壳体口，电器盒组件100内设有输入引线，输入引线连接光源组件，这样电能可由电器盒组件100传输至光源组件，并使光源组件通过光源件300发光，然后光线经透镜600的导光作用后，将由第二壳体口投射至外界，从而实现灯具的照明，下面对光源组件的内部部件进行详细介绍。
请参考图1～图6，本发明公开的光源组件还可以包括电路板400。电路板400用于传输光源件300发光所需的电能，其结构可以是COB电路板等。具体来说光源件300、电路板400和光源支架500可以依次叠置。
如图2所示，电路板400上设有弹性件，光源件300通过弹性件弹性连接于电路板400，比如在光源件300和弹性件的一者上设置卡扣，另一者上设置相匹配的卡孔，以实现两者的相互卡接等。弹性件的设置可以使电路板400成为柔性结构，并使光源件300和电路板400之间的连接具有柔性，具 体来说弹性件可以是设于电路板400上的弹簧、簧片、弹性条等一种或多种组合构成的结构。
如图6所示，光源支架500可以设有卡接部520，卡接部520可以实现连接光源件300和电路板400。具体来说，光源件300和电路板400构成的整体形成光源板，光源板通过卡接部520卡接于光源支架500，比如卡接部520为活动夹板、活动盖板等结构，从而使光源件300和电路板400均被夹紧固定在光源支架500上。
可见，在此种结构的设置中，弹性件的设置使电路板400具有柔性，这样随着光源支架500施加的夹紧力的变化，电路板400上的弹性件将进行不同程度的弹性形变，而在该弹性形变的作用下，能够将产生于光源件300和电路板400之间的挤压力，尤其是产生于光源件300和弹性件连接位置之间的挤压力进行卸除，从而可以较好的避免对光源件300造成过度挤压，进而避免过度挤压造成光源件300出现开裂等损坏，以及避免过度挤压造成光源件300和电路板400之间，尤其是光源件300和弹性件之间的连接失效。
在更为具体的实施方案中，如图2所示，电路板400可以设有第一透光孔440，光源件300发出的光线可以穿过第一透光孔440进行投射。弹性件可以是与第一透光孔440适配的结构，具体来说弹性件可以为弹条410，弹条410可以位于第一透光孔440外缘。
光源件300的发光侧连接弹条410，发光侧设有发光区，发光区内可以设置发光部件，以COB光源结构的光源件300为例，发光区可以设置为高反光率的镜面金属基板，并且在该基板上贴设LED芯片，从而达到发光效果。发光区朝向第一透光孔440，这样发光区发出的光线可经第一透光孔440射出。
更进一步的，弹条410可以设置为弧形。具体来说弹条410可以设置为圆弧形，并且弹条410可以沿第一透光孔440周向设置。弹条410的半径和第一透光孔440半径一致，弹条410朝向第一透光孔440的弧面可以构成第一透光孔440的部分孔面，以提高电路板400的整体集成度，也便于制造和 装配。
更进一步的，如图5所示，光源件300上可以设置透光凸起320。透光凸起320可以是透明罩壳，该透明罩壳对发光体进行包覆。透光凸起320与第一透光孔440适配，比如两者之间进行过盈配合或间隙配合，这样透光凸起320可设于第一透光孔440中，比如两者之间为过渡配合或者间隙配合，这样可以实现光源件300和电路板400的快速定位。
更为具体的，弹条410可以设置两个，两个弹条410对称设于第一透光孔440两侧，这样能够提供更为稳定的弹性支撑于光源件300。当然，也可以设置三个以上的弹条410周向阵列均布在第一透光孔440外缘，这里不再详述。
更进一步的，弹条410的两个相对端分别为连接端和自由端。连接端连接电路板400，弹条410通过自由端弹性连接光源件300，弹条410发生弹性形变时，其自由端的行程变化最大，将光源件300与自由端连接，能够更好的实现调整与电路板400之间的相对位置，从而达到更好的卸力效果。
如图2和图5所示，对于光源件300和电路板400的具体连接方式来说，可以在光源件300朝向电路板400的一面设置第一焊接区310，以及在弹条410朝向光源件300的一面设置第二焊接区430，以便光源件300通过第一焊接区310焊接于第二焊接区430，进而实现光源件300焊接连接电路板400。
在更进一步的实施方案中，光源件300和电路板400之间可以通过SMT回流焊的方式进行相互焊接，为了进一步加强此种焊接方式的牢固性，可以如图3所示，在弹条410设置通孔470。该通孔470沿弹条410的厚度方向开设，通孔470具有相对的第一孔口和第二孔口，第一孔口位于第二焊接区430，第二孔口位于弹条410背离第二焊接区430的一侧。焊接时将焊锡膏涂覆在第二焊接区430，部分焊锡膏将由第一孔口经通孔470流入第二孔口，最终留存在弹条410背离第二焊接区430的一侧，此种方式可以使弹条410两相对侧均存在焊锡膏，从而可以增强焊接力，使光源件300更为牢固的焊接在弹条410上。
作为替代的方案，也可采用粘接方式替代焊接，比如通过在弹条410上涂抹导电胶，并使导电胶留存在通孔470处、以及位于弹条410的两侧，也能够达到光源件300牢固连接弹条410的效果，这里不再详述。
更为具体的，第二焊接区430可以位于弹条410的自由端，如上所述，在此位置连接光源件300，可以较好的卸除光源件300的挤压受力，以及防止光源件300和弹条410之间出现脱焊等连接失效的异常。
更进一步的，弹条410的两相对面可以为平面，以便焊锡膏等材料更好的附着在弹条410上，从而使弹条410与光源件300之间的连接更加牢固。
在一些可选的实施方案中，卡接部520的具体结构如图6所示，光源支架500可以包括限位柱510和基台540，基台540为光源支架500的基础承载结构。
基台540可以设有第二透光孔550。第二透光孔550与第一透光孔440开设方向一致，第二透光孔550与第一透光孔440构成的整体形成透光孔，该透光孔的设置可以使光源组件实现照明。具体来说，第一透光孔440位于发光区和第二透光孔550之间，这样发光区发出的光线依次经第一透光孔440、第二透光孔550射出至外界。
限位柱510可以凸设于基台540朝向电路板400的一侧，限位柱510上设有卡缝，卡缝即为卡接部520。光源件300和电路板400均卡设于卡缝中，依靠卡缝的卡接作用可以同时对光源件300和电路板400施加夹紧力，从而使光源件300和电路板400固定在限位柱510上。
更为具体的，电路板400设有光源安装区，光源安装区位于电路板400的中间区域，光源件300可以设于光源安装区。电路板400围绕光源安装区的部分为搭接板，搭接板设有限位缺口420，限位缺口420与限位柱510适配。在具体装配时，先将光源件300和电路板400焊接为一体，然后将限位缺口420对准限位柱510，接着将光源件300和电路板400构成的整体朝向基台540下压，并使光源件300和电路板400最终卡设于卡接部520中，在此种情况下，限位缺口420所在位置与限位柱510重合，限位缺口420与限 位柱510限位配合，限位柱510可以止挡电路板400进行周向转动。
可见，限位缺口420和限位柱510的配合设置，可以使光源件300和电路板400所构成的整体按照特定的方位装配在光源支架500上，从而加快本发明装置的装配效率，以及能够对电路板400和光源件300构成的整体起到周向固定作用。
更为具体的，卡接部520可以设置在限位柱510与基台540连接处，这样搭接板可以搭接在基台540中用于设置限位柱510的台面上。同时限位柱510可以对称设置两个，相应的限位缺口420也设置两个，以达到更好的限位效果。
更进一步的，限位柱510可以设有螺纹孔，螺纹孔沿限位柱510的轴向开设，并由限位柱510远离基台540的一端贯通至卡接部520。螺纹孔内可以设置螺纹连接的锁紧螺栓530，这样当旋入锁紧螺栓530时，可以使锁紧螺栓530压紧光源件300和电路板400在卡接部520中，进而对光源件300和电路板400产生更为有效的固定效果。
更进一步的，如图4所示，电路板400可以设有第三焊接区460。第三焊接区460设于电路板400远离第一透光孔440的一侧。电器盒组件100中的输入引线可以在罩壳200内部走线，并连接至第三焊接区460，以便使电能经第三焊接区460传输至第二焊接区430，并最终进入光源件300，使光源件300发光。
此布局方式可以减少焊接位置的设置，也能够防止设置的输入引线进入第一透光孔440所在位置，避免对光源件300的发光干涉。更进一步的，第三焊接区460设于电路板400中背离第二焊接区430的一侧，并设于电路板400的搭接板上，这样第三焊接区460能够更加远离第二焊接区430，以起到更好的防干涉效果。
同时，基台540上还可以设置避让缺口560。避让缺口560可以设于第二透光孔550一侧，第三焊接区460朝向避让缺口560设置，并且第三焊接区460与避让缺口560底面间隔设置，这样便于输入引线连接第三焊接区 460。
更进一步的，电路板400背离光源支架500一侧可以设置安装槽450。安装槽450即为光源安装区，安装槽450与光源件300形状适配，光源件300可以设于安装槽450中，比如光源件300为矩形光源板结构，而安装槽450为矩形槽，光源件300可以嵌装在安装槽450中，当然光源件300的外形也可以是圆形等其他形状，而安装槽450也为与光源件300保持一致的形状，本发明中不做限制。同时，第一透光孔440、弹条410可以均设于所述安装槽450的槽底，以便与光源件300进行相应的配合。
此种设计可以起到对光源件300的预定位作用，并且能够在使用过程中，通过安装槽450的约束，防止光源件300出现晃动或者位置偏移，更为有效的保证光源件300和电路板400之间的连接牢固性、以及相对位置的准确性。
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。
