如图1至图13所示，本实用新型实施例提供一种光源可替换的灯具，举例来说，其可以为悬挂安装的线性照明灯具，或固定安装至天花板或吊顶的灯具。该灯具的光源部分可以替换，以降低长期的使用成本，光源损坏时，仅需更换光源即可。
本实施例中的光源可替换的灯具，具体可包括：底座1、安装单元2及光源模组3。其中，安装单元2固定于底座1上，而光源模组3可以通过可拆卸的方式安装至安装单元2上，以实现光源模组3的可替换性。
参见1至图7，光源模组3可以是直管灯，例如LED直管灯。具体的，光源模组3包括灯管31和灯头32，灯头32上设置有导电针35。灯管31内可设置灯板33及LED灯珠34，LED灯珠34设置于灯板33上。另外，光源模组3还可包括电源，电源可设置于灯头32和/或灯管31内。安装单元2上设置有灯座4，导电针35可与灯头21固定，并实现电性连接。
参见图1至图7及图12至图13，本实用新型于一实施例中提供一种底座1，可应用于前述实施例中。具体的，底座1具有正面及相对的背面，其中光源模组3配置于底座1的正面。底座1正面内凹而形成容置空间11。在底座1的高度方向上，光源模组3完全位于容置空间11所限定的范围内。
底座1的正面的容置空间11的内轮廓的截面积及底座1的背面的外轮廓的截面积分别在底座1的高度方向上逐渐递减。而底座1的正面的内轮廓的截面形状或形状与底座1的背面 的外轮廓的截面形状或形状相配。以使得两个底座1可叠置，且两个底座1叠置后的总高度小于底座1的高度的两倍。在一些实施例中，底座1采用金属片状体冲压成型，多个底座1叠置后其总高度H满足以下关系：H＝X+(n-1)Y；
其中，X为单个底座1的高度；n为底座1叠置的数量；Y为每叠置一个底座1时所增加的高度；
一些实施例中Y的值满足以下关系式：Y<0.4X；一些实施例中Y的值满足以下关系式：Y<0.3X；一些实施例中Y的值满足以下关系式：Y<0.2X；一些实施例中Y的值满足以下关系式：Y<0.1X。以此可控制底座1叠加后高度。
底座1的正面设有反射表面12，以用于反射至少部分光源模组3工作时产生的光。
一实施例中，光源模组3在安装时，可使其灯板33垂直于底座1正面(或底座1的安装面13)，以使灯板33上的LED灯珠34侧向出光。此时，反射表面12可至少延伸至光源模组3的侧面，以使LED灯珠34正面对应于反射表面。从另一方面讲，光源模组3沿垂直于LED灯珠34表面方向上投影至反射表面12所在面时，完全落入反射表面12所在面所限定的范围内。以此，可使从光源模组3射出的光的至少40％、45％、50％、55％、60％的光经反射表面12反射后，从灯具射出，使得灯具出光更加柔和，避免光线直射而刺眼。另外，反射表面12至少延伸至光源模组3的侧面，可减小灯具侧部的出光，从而可降低眩光。
本实施例中，光源模组3设置有两组，两组光源模组3的灯板33相背设置，即两灯板33分别与底座1正面呈垂直关系，两组LED灯珠34于相反的方向出光。
一些实施例中，光源模组3在安装时，也可使其灯板33出光表面与底座1正面(或底座1的安装面13)呈现一夹角，以使光源模组3工作时产生的光更多的以反射的形式从灯具射出，能进一步降低炫光。前述夹角为锐角，即小于90度。
一些实施例中，光源模组3在安装时，也可使其灯板33平行于底座1正面(或底座1的安装面13)，以使光源模组3工作时产生的光更多的以直射的形式从灯具射出，以提高灯具的出光效率。
参见图2至图13，本实用新型于一实施例中提供一安装单元2，可应用于前述实施例。安装单元2包括基座21和固定单元22，其中，灯座4固定于基座21上，而安装单元2可通过固定单元22而固定至前述实施例的底座1。基座21设置于底座1的背面，光源模组3的端部的至少一部分穿过底座1(底座1上设置通孔101，光源模块3的端部通过通孔101而穿过底座1)而与基座21上的灯座4连接。本实施例中的光源模组3的端部为不发光区域(不发光区域可为灯头32区域及灯管31的端部不设置LED灯珠34的区域)。光源模组3的端部的至少一部分穿过底座1而位于底座1的背面。也就是说，光源模组3的不发光区域的至少一部分被底座遮挡，露于底座1的正面部分的光源模组3的发光区域的比例增加，可减小露于底座1正面部分的光源模组3的暗区。
至少其中一组基座21上设置接线端子201，以用于连接外部电源。
安装单元2可进一步包括走线单元23。基座21设置有两组，走线单元23设置于两组基 座21之间，以此可使安装单元2形成为一整体。走线单元23内部具有空腔，以此可使线缆从走线单元23通过，并避免线缆被暴露在灯具外部。
本实施例中，固定单元22可设置于走线单元23上。其他实施例中，固定单元22也可设置于基座21上。固定单元22包括一卡扣221，而底座1上设置有相应的扣合孔14，卡扣221可扣入扣合孔14进行固定。安装时，将安装单元2的卡扣221扣入底座1的扣合孔14，即可完成固定，连接非常方便。
卡扣221为一片体，其可通过冲压等工艺直接在走线单元23的壁上形成。卡扣221扣入扣合孔14后，便无法进行拆卸。其他实施例中，固定单元22也可采用可拆卸的方式与底座1进行固定。
底座1的背面设置一凹部15，走线单元23至少一部分容置于凹部15内。一方面，底座1上设置凹部15，凹部15可起到增加底座1的结构强度的作用，另一方面，走线单元23至少一部分容置于凹部15，可降低灯具整体的高度。一些实施例中，走线单元23于底座1的高度方向上的至少60％、65％或70％容置于凹部15内。
同样的，走线单元23也可与基座21采用大致相同的固定方式。即走线单元23上设置卡扣221，而基座21上设置对应的扣合孔211。
基座21的上表面大致与走线单元23的上表面持平。因此，相较走线单元23而言，基座21并不会额外增加灯具的整体的高度。另外，一实施例中，在走线单元23的长度方向上，基座21的至少80％、85％或90％的长度是位于底座1限定的范围内。一实施例中，在走线单元23的长度方向上，基座21完全位于底座1限定的范围内。
基座21具有端壁212，灯座4固定于端壁212上。一基座21上，灯座4可设置有两组。端壁212可以位于光源模组3的长度方向上的一侧，也可位于光源模组3的径向方向上一侧。
参见图14至图17，本实用新型于一实施例中提供一种底座100，可应用于前述实施例中。本实施例中的底座100的结构大致同前述实施例中的底座。例如，底座100具有正面及相对的背面，其中光源模组3配置于底座100的正面。底座100正面内凹而形成容置空间1001。在底座100的高度方向上，光源模组3完全位于容置空间1001所限定的范围内。例如底座100之间可相互叠加等。
光源模组3也可同前述实施例中的光源模组。所不同的是，光源模组3的安装角度不同于前述实施例。具体的，光源模组3可设置多组(例如4组)，当底座100沿水平面安装时，光源模组3的LED灯珠的光轴垂直或大致垂直于水平面。
参见图14至图18，本实用新型于一实施例中提供一种安装单元200，可应用于前述实施例中。安装单元200包括两组基座2001，两组基座2001分别设置于底座100的两侧。灯座4固定于基座2001上。光源模组3(直管灯)的一端与底座100一侧的基座2001上的灯座4连接，而光源模组3的另一端与底座100相对的另一侧的基座2001上的灯座4连接。
安装单元200可进一步包括走线单元2003，走线单元2003包括线缆，走线单元2003电性连接两组基座2001上的灯座4。本实施例中，底座100的正面设置凹槽1002，而走线单元 2003配置于所述凹槽1002内，相比将走线单元2003设置于底座100背面，其占用底座100的高度尺寸更小，更利于整灯高度的控制。本实施例中，底座100的背面的相对凹槽1002处设置接线端子1004。
参加图14至图21，本实施例中可进一步包括一盖体20031，盖体20031连接在底座100上，并将凹槽1002盖住，并且盖体20031与凹槽1002之间可形成一走线通道，线缆可从该走线通道穿过。通过盖体20031的设置，可避免线缆外露。
盖体20031上设置有插接部20311，底座100上设置有插接孔1003，盖体20031的插接部20311插入底座100的插接孔1003，以使盖体20031固定在底座100上。
参见14至图17，图19和图20，基座2001包括第一构件2011和第二构件2012，其中，第一构件2011固定于底座100上，且第一构件2011与底座100的背面之间形成一端部空间2111。灯座4设置于端部空间2111内。
底座100上开设有通孔，光源模组3的端部穿过底座100上的通孔进入端部空间2111，并与灯座4连接。本实施例中的光源模组3的端部为不发光区域(不发光区域可为灯头32区域及灯管31的端部不设置LED灯珠的区域)。光源模组3的端部的至少一部分穿过底座100而位于底座100的背面。也就是说，光源模组3的不发光区域的至少一部分被底座100遮挡，露于底座100的正面部分的光源模组3的发光区域的比例增加，可减小露于底座100正面部分的光源模组3的暗区。
灯座4可固定于第一构件2011或第二构件2012上。一实施例中，灯座4固定于第二构件2012上。
本实施例中的第一构件2011与第二构件2012之间形成腔体，所述腔体与走线通道连通，以便于接线单元2003进入腔体，并且腔体的设置，便于在其内部布置线路，以用于与灯座4连接。
参见图14至图16，及图21，本实用新型于一实施例中提供一种光学构件500，可应用于前述实施例中。光学构件500设置于底座100上，且光学构件500可具有光扩散功能。且在光源模组3的光轴方向上，光学构件500完全覆盖光源模组3的出光部分(可不包括直管灯的灯头部分)，以减小光源模组3工作时沿光轴方向的局部的强光。也就是说，在光源模组3的光轴方向上或灯具的厚度方向上，光源模组3投影至光学构件500所在的平面时，光源模组的投影完全落入光学构件500所在的平面的范围。
本实施例中的光学构件500的一端铰接于所述底座100，另一端则可拆卸的固定于底座100上，以此，将光学构件500的一端从底座100拆下后，可旋转光学构件500，以使光源模组暴露，此时，便可对光源模组3进行安装、更换或维护。
光学构件500在其宽度方向的两侧设置有防眩光部501，防眩光部501设置于光学构件500靠近光源模组3的一侧。通过防眩光部501的设置，可减小灯具出光时的眩光。
防眩光部501包括若干沿光学构件500的长度方向上延伸设置的齿部501。齿部501可将至少一部分光进行反射，以减小光源模组3侧向的出光，从而降低灯具的眩光。
光学构件500为一片状体，光学构件500的截面形状呈弧形。进一步的，光学构件500相对底座100的下端面呈内凹状。
参见图22至图31，本实用新型于一实施例中提供一种底座1a，可应用于前述实施例中的光源可替换的灯具。具体的，底座1具有正面及相对的背面，其中光源模组3a(此处的光源模组3a可同前述实施例中的光源模组3)配置于底座1a的正面，光源模组3a可配置4组。底座1a正面内凹而形成容置空间11a。在底座1a的高度方向上，光源模组3完全位于容置空间11a所限定的范围内。
底座1a的正面设有反射表面12a，以用于反射至少部分光源模组3a工作时产生的光。光源模组3设置多组时，可在底座1a的宽度方向上均匀排布。底座的反射表面12a的两侧形成弧面121a，底座1a宽度方向上的相对外侧的光源模组3a对应于弧面121a(即底座1a宽度方向上的相对外侧的光源模组3a发出的光至少一部分经弧面121a反射而从灯具射出)。
参见图22至图34，本实用新型于一实施例中提供一种安装单元2a，可应用于前述实施例中的光源可替换的灯具。安装单元2a设置有两组，且两组安装单元2a分别设置于底座1a的长度方向上的两侧(光源模组3a的轴向方向上的两侧)。安装单元2a在底座1a的长度方向上形成底座1a的端部，并且安装单元2a提供对灯座4a的安装固定(即安装单元2a上具有灯座4a)。光源模组3a通过两组安装单元2a上的灯座4a而实现固定及电性连接，并且光源模组3a与灯座4a之间的连接为可拆卸式的。
具体的，安装单元2a包括端盖21a，其中端盖21a设置有两组，两组端盖21a分别设置于底座1a的长度方向上的两侧(光源模组3a的轴向方向上的两侧)。端盖21a通过第一固定结构23a而固定至底座1a上。第一固定结构23a包括第一定位单元231a及第二定位单元232a，端盖21a的长度方向的两侧通过第一定位单元231而固定至底座1，端盖21a的厚度方向上则通过第二定位单元232a与底座1a进行固定。
第一定位单元231a包括紧固件和对应的孔洞，该紧固件可以是螺丝或铆钉。孔洞设置于端盖21a上，而底座1a则对应设置孔洞。第一定位单元231也可以是焊料，即，端盖21a的长度方向的两侧通过焊接与底座1固定。
第二定位单元232a包括抵接壁2321a，抵接臂2321a抵于端盖21a上，并使端盖21a被夹持在抵接臂2321与底座1a的本体之间。换句话说，端盖21a在底座1a的长度方向上的自由度被限定。
第一固定结构23a还可包括第三定位单元233a，第三定位单元233a包括插槽2331a和插接壁2332a。插槽2331a可设置于底座1a上，而插接壁2332a则设置于端盖21a上，插接壁2332a插入插槽2331a而固定。
一些实施例中，安装单元2a的端盖21a可通过第一定位单元231a、第二定位单元232a和第三定位单元233a与底座1a固定。一些实施例中，安装单元2a的端盖21a通过第一定位单元231a、第二定位单元232a或第三定位单元233a中的一组或两组而固定至底座1a上。
端盖21a上设置有安装构件211a，安装构件211a用于固定灯座4a。安装构件211a包括 卡槽2111a和抵接臂2112a，灯座4a卡入卡槽2111a中，并且在端盖21a的作用下，限制灯座4a在底座1a的长度及宽度方向上的活动。抵接臂2112a则压在灯座4a上，以此便可将灯座4a完全固定在灯具上。上述对灯座4a的固定结构非常简单，且便于进行组装，可提高装配效率。
安装单元2a还可包括走线单元24a，走线单元24a内部用于布置导线，导线可将底座1a长度方向上的两侧的灯座4a实现电性连接。
走线单元24a包括盖体241a，盖体241a固定至底座1a上，且盖体241a与底座1a之间形成走线的通道。
盖体241a上可设置卡扣2411a，而底座1a上设置有扣合孔13a，盖体241的卡扣2411a插入或扣入扣合孔13a中，以使盖体241a固定至底座1a。
盖体241a包括抵紧面2412a和压迫面2413a，盖体241a固定至底座1a时，抵紧面2412a可在底座1a的长度方向上(光源模组3a的轴向方向)上推抵端盖21a或限制端盖21a的进一步的活动，而压迫面2413则压迫于端盖21a，从而在底座1a的厚度或高度方向上限制端盖21a的活动。也就是说，通过盖体241a的设置，可进一步对端盖21a起到固定作用，提高端盖21固定时的结构的稳定性。
参见图22至图39，本实用新型于一实施例中提供一种光学构件5a，可应用于前述的实施例中的光源可替换的灯具。光学构件5a作为一整体罩设于光源模组3a的出光方向上。另外，光学构件5a可仅覆盖于具有光源模组3a的区域，而不覆盖底座1a上类似弧面121a等区域，以防止光学构件5a影响到弧面121a处的反射。
光学构件5a具有透光部51a及防眩光部52a。透光部51a配置为用于光源模组3a点亮时发出的光透过。本实施例中，光学构件5a于透光部51a处不设置光学材料，例如透光材料或光扩散材料等，以降低因出光过程中经过光学材料而造成的光损。具体的，光学构件5a于透光部51a处镂空设置。
防眩光部52a包括若干防眩光单元，防眩光单元包括第一防眩光部521a及第二防眩光部522a，其中，第一防眩光部521a大致是沿光源模组3a的长度方向延伸设置的，而第二防眩光部422a则大致是沿光源模组3a的宽度方向延伸设置的。第一防眩光部521a可反射至少部分光源模组3a直接或间接射至第一防眩光部521a的光，并将该部分光中的至少一部分反射至透光部51a。由于第一防眩光部521a的挡光作用，可减小灯具在其长度方向上的眩光值(UGR值)。
第一防眩光部521a还可配置有光透过的功能，以提升光学构件5a的视觉效果。具体的，光源模组3a直接或间接设置第一防眩光部521a的光的一部分进入第一防眩光部521a，并最终从光学构件5a射出。此时，第一防眩光部521a可采用塑料或亚克力等材质制成，以使其具有透光及反射功能。其他实施例中，第一防眩光部521可配置为仅具有反射功能，其材质可采用金属材质。
同样的，第二防眩光部522a可反射至少部分光源模组3a直接或间接射至第一防眩光部 522a的光，并将该部分光中的至少一部分反射至透光部51a。由于第二防眩光部522a的挡光作用，可减小灯具在其宽度方向上的眩光值(UGR值)。
第二防眩光部522a还可配置有光透过的功能，以提升光学构件5a的视觉效果。具体的，光源模组3a直接或间接设置第二防眩光部522a的光的一部分进入第二防眩光部522a，并最终从光学构件5a射出。此时，第二防眩光部522a可采用塑料或亚克力等材质制成，以使其具有透光及反射功能。其他实施例中，第二防眩光部522a可配置为仅具有反射功能，其材质可采用金属材质。
LED灯珠34a的光束角为A，光束角的定义为现有技术，此处不再赘述。可选的，光束角A的取值可在100至130度之间。如图37所示，在光源组件3a的宽度方向上的两侧对应设置两组第一防眩光部521a。LED灯珠34a的中心分别与对应的两组第一防眩光部521a的下端部的连线之间形成一夹角B，夹角B小于光束角A。一些实施例中，夹角B的角度小于80度、70度或60度，但大于30度或40度。以此来更好的对光源模组3a的宽度方向进行挡光，并起到在该方向上降低眩光的作用。
如图39所示，在光源组件3a的长度方向上的两侧对应两组第二防眩光部522a。对应同一防眩光单元的LED灯珠34中的任意一颗LED灯珠34a的中心分别与对应的两组第二防眩光部522a的下端部的连线之间形成一夹角C，夹角C小于光束角A。一些实施例中，夹角C的角度小于85度、80度、75度或70度，但大于30度或40度。以此来更好的对光源模组3a的长度方向进行挡光，并起到在该方向上降低眩光的作用。
光学构件5a可采用可拆卸的方式固定至底座1a，或采用可打开式的方式固定至底座1a，以便于对光源模组3进行更换。
