如图1A至图1F所示,本发明于一第一实施例中提供一种LED照明设备,该LED照明设备包括:光源载体1、发光单元2、光学构件3及电源4。其中,发光单元2固定于光源载体1上,光学构件3罩设于或至少部分罩设于发光单元2上,以使发光单元2点亮时,其所发出的光的至少一部分或全部经光学构件3而从LED照明设备射出。本实施例中的发光单元2以不可拆卸的形式(不可替换)固定于光源载体上(因此可称之为一体式照明设备)。
本实施例中的光源载体1包括基座11及设于基座11两端的端盖12。基座11限定一安装表面111,发光单元2固定于所述安装表面111。进一步的,发光单元2包括基板21及发光体22,发光体22固定于基板21上,发光体22可以为LED灯珠。基板21贴设于安装表面111,如基板21采用胶而粘接于安装表面111,或者安装表面111设置安装结构,以将基板21以卡接、扣接、螺纹连接、磁吸等方式贴合于安装表面11。本实施例中,基座11采用金属材质,而发光单元2固定于安装表面111后,发光单元2与基座11形成导热路径。以此,发光单元2点亮时产生的热量可传导至基座11,并借由基座11进行散热。本实施例中的安装表面111配置为具有反射功能。具体的,安装表面111可设置反光层(如白漆),以使其具有反射功能。其他实施例中,也可不设置上述的端盖,也就是说,光源载体1由基座11一体式形成。此时,可在基座11上设置加强件(如基座11上直接形成如加强筋等加强结构,或者基座11上额外设置加强构件),以增加基座11的结构强度。该实施例中,由于取消端盖,电源4将配置于基座11上,如配置在基座11的背面或正面。
本实施例中的端盖12通过固定结构而固定于基座11上。具体的,端盖12可通过卡接、扣接或通过螺栓的方式固定于基座11上。
本实施例中的端盖12包括壁部121,所述壁部121限定一第一容置空间1211。所述电源 4设置于第一容置空间1211内。相比将电源设置于基座11背面(基座11上相对与发光单元2的另一侧),将电源设置于端盖12内(即设置于第一容置空间1211内),可降低LED照明设备的整体的高度尺寸。本实施例中,LED照明设备的高度尺寸小于30mm。进一步的,本实施例中的端盖12在LED照明设备的高度方向上,均不超过基座11所限定的高度空间(即基座11在LED照明设备高度方向上的上端及下端)。本实施例中的壁部121的至少一部分往LED照明设备的内侧(在第一方向X的内侧)突出,以在其内部形成所述第一容置空间1211。本实施例中的端盖12为一体式结构构成。
本实施例中的壁部121进一步限定第二容置空间1212,第二容置空间1212与第一容置空间1211连通。第二容置空间1212沿一第二方向Y延伸设置。本实施例中的发光单元2与电源4通过一电连接单元连接,所述电连接单元一端与发光单元2连接,而其另一端与电源4连接,且电连接单元至少部分位于所述第二容置空间1211内,以做到隐藏式走线。本实施例中的电连接单元为导线或柔性连接板(如FPC板)。本实施例中的第一容置空间1211在第一方向X上的宽度大于第二容置空间1212在第一方向X上的宽度,因此,可使发光单元2在第一方向X上具有更多的空间进行布置(如提高发光体22的数量或发光体22之间的间距)。
本实施例中的发光单元2设置为两组,基座12的第一容置空间1211的两侧分别设置第二容置空间1212,以用于两组发光单元2的走线。
本实施例中,发光单元2的基板21的端部进入所述第二容置空间1212内,并使所述电连接单元全部位于第二容置空间1212和/或第一容置空间1211内。本实施例中的至少一个发光体22位于所述第二容置空间1212内,且该位于第二容置空间1212内的发光体22被点亮时,其发出的光线的至少部分透过端盖12而射出,避免在端盖12处形成暗区。
本实施例中,可进一步包括接线端子,接线端子设置于其中一端盖12中。接线端子可与电源4设于同一端盖12的第一容置空间1211内,也可分别设置于不同的端盖12的第一容置空间1211内。本实施例采用的是将电源4设置于其中一端盖12的第一容置空间1211内,而将接线端子设于另一端盖12的第一容置空间1211内。本实施例中的接线端子配置为用于与发光单元2连接或与外部电源连接。
本实施例中的接线端子与电源通过一导线连接。导线可沿安装表面111设置,且其两端分别进入两侧的端盖12的第一容置空间1211内。进一步的,本实施例中的LED照明设备还包括一穿线单元5,所述穿线单元5具有一穿线孔51,该穿线孔51沿第一方向X延伸设置,所述导线穿设于穿线单元5的穿线孔51中。
本实施例中的穿线单元5的两端可分别进入两组端盖12的第一容置空间1211内,以使得导线不会外露。本实施例中,穿线单元5具有一底部52,所述底部52贴设于安装表面111。穿线单元5可通过其底部52而固定于安装表面111,也可通过端盖12而将穿线单元5的两端固定,以使其大体上贴设于安装表面111。本实施例中的穿线单元5的设置,还可增加基座11的强度,限制其扭曲变形。其他实施例中,穿线单元5也可设置于基座11相对于发光单元2的另一侧。其他实施例中,当导线沿基座11背面走线(沿基座11相对于发光单元2 的另一侧走线)时,也可省略上述的穿线单元。但导线沿基座11背面走线时,会额外增加LED照明设备的整体的高度。
本实施例中的光学构件3贴设于安装表面111。进一步的,本实施例中的光学构件3可直接固定于安装表面111。一实施例中,光学构件3直接粘接于安装表面111。一实施例中,光学构件3通过固定结构固定于安装表面111,如通过螺栓、卡扣等。一实施例中,光学构件3两端通过两端盖12而压紧于安装表面111。
本实施例中,光学构件3配置为控制LED照明设备的出光角度及出光均匀性。例如,发光单元2点亮时射出的光线,经由光学构件3而从LED照明设备射出时,LED照明设备的发光角度控制为80度至130度。进一步的,发光单元2点亮时射出的光线,经由光学构件3而从LED照明设备射出时,LED照明设备的发光角度控制为90度至120度。更进一步的,发光单元2点亮时射出的光线,经由光学构件3而从LED照明设备射出时,LED照明设备的发光角度控制为90度至100度。
参见图1B、图1C及图1G,本实施例中,为控制LED照明设备的出光均匀性,发光单元2点亮时射出的光线,在一第一区域A范围内的照度与在一第二区域B范围内的平均照度的比值大于0.3、0.4、0.5、0.6、0.7、0.8或0.9,而小于2。一些实施例中,在一第一区域A范围内的照度与在一第二区域B范围内的平均照度的比值大于0.5,而小于1.5。一些实施例中,在一第一区域A范围内的照度与在一第二区域B范围内的平均照度的比值大于0.7,而小于1.3。其中,第一区域A与第二区域B位于同一平面上。且第一区域A及第二区域B均位于一第三区域C(第三区域C与第一区域A及第二区域B位于同一平面)内,而第三区域C对应的光束角c为90度、80度、60度或50度。本实施例中的光束角c可小于LED照明设备的发光角度。本实施例中,以光束角50度范围内的照度差异来考量出光均匀性,以此,第三区域C对应的光束角为50度。另外,第一区域A及第二区域B可以为第三区域C内的任意区域。需要注意的是,本处所指的光束角a并非指的有光范围的边界线所形成的夹角。本实施例中的第三区域C的中心或圆心的位置与LED照明设备对应,即LED照明设备沿光轴D投影至第三区域C时,其位置落于或大致落于第三区域C的中心或圆心。本实施例中,第一区域A与第二区域B所在的平面与光轴D垂直或大致垂直。
参见图1B、图1C及图1H,一实施例中,为控制LED照明设备的出光均匀性,发光单元2点亮时射出的光线,在一第一区域A范围内的照度与在一第二区域B范围内的平均照度的比值大于0.3、0.4、0.5、0.6、0.7、0.8或0.9,而小于2。一些实施例中,在一第一区域A范围内的照度与在一第二区域B范围内的平均照度的比值大于0.5,而小于1.5。一些实施例中,在一第一区域A范围内的照度与在一第二区域B范围内的平均照度的比值大于0.7,而小于1.3。其中,第一区域A与第二区域B位于同一平面上,且同心或大致同心设置(假设各区域为圆形或大致的圆形,其中心或圆心位于相同位置)。且第一区域A及第二区域B均位于一第三区域C(第三区域C与第一区域A及第二区域B位于同一平面)内,而第三区域C对应的光束角c为90度、80度、60度或50度。本实施例中的光束角可小于LED照明设 备的发光角度。本实施例中,以光束角50度范围内的照度差异来考量出光均匀性,以此,第三区域C对应的光束角c为50度。另外,第一区域A及第二区域B与第三区域C同心或大致同心设置,且第一区域A对应的光束角a和第二区域B对应的光束角b均小于第三区域C对应的光束角c。需要注意的是,本处所指的光束角并非指的有关范围的边界线所形成的夹角。本实施例中的第三区域C的中心或圆心的位置与LED照明设备对应,即LED照明设备沿光轴D投影至第三区域C时,其位置落于或大致落于第三区域C的中心或圆心。本实施例中,第一区域A与第二区域B所在的平面与光轴D垂直或大致垂直。
本实施例中的光学构件3包括第一配光单元31,所述第一配光单元31配置为控制发光体22工作时产生的光线从光学构件3射出时的发光角度(在第一方向X和/或第二方向Y上的发光角度)小于100度,以控制其眩光值。进一步的,第一配光单元31配置为控制发光体22工作时产生的光线从光学构件3射出时的发光角度(在第一方向X和/或第二方向Y上的发光角度)在90度至95度之间。本实施例中的第一配光单元31配置为具有若干配光部,微配光部可配置具有反射、折射、透光中的一种或多种功能,以使LED照明设备的出光角度小于发光体22原始(无光学构件时)的出光角度。
本实施例中的光学构件3具有一凹槽33,所述发光单元2容置于所述凹槽33内。本实施例中的发光单元2(基板21)的长度大于光学构件3。基板21的其中一端或者两端在其长度方向上露于光学构件3的外部,以便于进行电连接。
在一实施例中,光学构件3还可包括一第二配光单元31,所述第二配光单元31配置为将至少部分发光体22工作时产生的光线透过光学构件3而射至安装表面111上,以使安装表面111上呈现较佳光学效果。
一实施例中,光学构件3可以是一整体式结构而罩设于发光单元2上。一实施例中,光学构件3为多段式的,即一发光单元2对应设置多组光学构件3。
参见图2A至图2G,本发明于第二实施例中,提供一种LED照明设备,其基本结构可同前述实施例中的LED照明设备。于另一实施例中,本实施例中的发光单元2进一步包括灯管23,即发光单元2包括基板21、发光体及灯管23,发光体22可以为LED灯珠,发光体22固定于基板21上,而基板设置于灯管23的内周面。而灯管23可贴设于安装表面111,或与安装表面111保持间距。
另外,本实施例中光学构件3包括第一配光单元301及第二配光单元302,第一配光单元301配置为片状结构且沿第一方向X延伸设置,而第二配光单元301配置为片状结构且沿第二方向Y延伸设置。发光单元2在第二方向Y上的两侧分别配置第二配光单元302。在第一方向X上配置多组第一配光单元301。本实施例中的第一配光单元301及第二配光单元302表面均具有光反射功能。
本实施例中的多组第一配光单元301及多组第二配光单元302共同形成若干配光腔303,若干配光腔303沿第一方向X排布,配光腔303具有反射壁(由第一配光单元301及第二配光单元302的侧壁形成)。发光单元2宽度方向上的至少一部分位于配光腔303内。由于反射 壁的设置,可限制发光单元2的出光角度,以起到控制眩光的作用。
本实施例中的第一配光单元301与安装表面111之间具有间隔,所述发光单元2工作时产生的光至少部分透过所述间隔,以使基座11上不会存在明显的暗区,提升照明效果。本实施例中的第二配光单元302贴合于安装表面111,如第二配光单元302与安装表面111的间距小于5mm,则也可算第二配光单元302贴合于安装表面111。
本实施例中的第二配光单元302上设置槽部3021,所述发光单元2的灯管23卡设于槽部3021。也就是说,第一配光单元301承托所述发光单元2,以完成发光单元2的安装,结构更加简单,无需将发光单元2固定至安装表面111。安装时,先将灯管23卡入槽部3021,再将光学构件3连同端盖12一起,直接固定至基座11。
本实施例中的光源载体1同样包括基座11及设于基座11两端的端盖12。基座11限定一安装表面111,发光单元2对应于所述安装表面111(发光单元2可不与安装表面111直接固定)。
本实施例中的端盖12通过固定结构而固定于基座11上。具体的,端盖12可通过卡接、扣接或通过螺栓的方式固定于基座11上。
本实施例中的端盖12同样可包括壁部121,所述壁部121限定一第一容置空间1211第二容置空间1212,其具体结构大致同前述实施例,此处不再赘述。
本实施例中,发光单元2的端部进入所述第二容置空间1212内(灯管23进入到第二容置空间1212),并使所述电连接单元全部位于第二容置空间1212和/或第一容置空间1211内。本实施例中的至少一个发光体22位于所述第二容置空间1212内,且该位于第二容置空间1212内的发光体22被点亮时,其发出的光线的至少部分透过端盖12而射出,避免在端盖12处形成暗区。
本实施例中,也可进一步包括接线端子。本实施例采用的是将电源4设置于其中一端盖12的第一容置空间1211内,而将接线端子设于另一端盖12的第一容置空间1211内。本实施例中的接线端子配置为用于与发光单元2连接或与外部电源连接。
本实施例中的接线端子与电源通过一导线连接。导线可沿安装表面111设置,且其两端分别进入两侧的端盖12的第一容置空间1211内。进一步的,本实施例中的LED照明设备还包括一穿线单元5,与前述实施例不同的是,本实施例中的穿线单元5直接形成于光学构件3上,且穿线单元5上设置一槽部53,以用于容纳导线。或者,穿线单元5仅起到遮蔽作用,其罩于导线外侧,以使得外部观察不到导线的存在。
本实施例中的端盖12、光学构件3及穿线单元5为一体式结构构成。三者一体式注塑而形成,以使得加工更加方便,且三者一体化后,安装更加简便。
如图3A至图3E所示,本发明于第三实施例中提供一种LED照明设备,本实施例中的基本结构可同前述实施例。本实施例中的LED照明设备包括:光源载体1、发光单元2、光学构件3及电源4。其中,发光单元2固定于光源载体1上,光学构件3罩设于或至少部分罩设于发光单元2上,以使发光单元2点亮时,其所发出的光的至少一部分或全部经光学构 件3而从LED照明设备射出。本实施例中的发光单元2以不可拆卸的形式(不可替换)固定于光源载体上(因此可称之为一体式照明设备)。
参见图3A至图3D,本实施例中的光源载体1包括底座101(可不包括前述端盖)。底座101限定一安装表面1011,发光单元2直接或间接的固定于所述安装表面1011。进一步的,发光单元2包括灯板201及发光体202,发光体202固定于灯板201上,发光体202可以为LED灯珠。本实施例中,灯板201贴设于安装表面1011,如灯板201采用胶而粘接于安装表面1011,或者安装表面1011设置安装结构,以将灯板201以卡接、扣接、螺纹连接、磁吸等方式贴合于安装表面1011。本实施例中,灯板201固定于安装表面1011后,发光单元2与底座101形成导热路径。以此,发光单元2点亮时产生的热量可传导至底座101,并借由底座101进行散热。
本实施例中,底座101上形成容置空间1012,发光单元2和光学构件3均设置于容置空间1012内,且在底座101高度方向上,发光单元2和光学构件3均不超过容置空间1012限定的范围。
本实施例中,容置空间1012由一第一壁部10121和一第二壁部10122形成,并且,第一壁部10121和一第二壁部10122均为底座101的组成部分。第一壁部10121围绕第二壁部10122而设置,且第一壁部10121相对底座101的下端壁10123而凸出。第二壁部10122可平行或大致平行于底座101的下端壁10123。通过第一壁部10121和一第二壁部10122的设置,可提高底座101的结构强度。
本实施例中的电源4设置于底座101上相对发光单元2的另一侧。具体的,在LED照明设备的高度(或厚度)方向上,电源4被限制在第二壁部10122和下端壁10123所限定的高度(或厚度)范围内。也就是说,电源4不会额外占用LED照明设备的高度(或厚度)尺寸,以控制LED照明设备的高度(或厚度尺寸),以利于包装尺寸的控制,降低运输成本。
在一实施例中,容置空间1012设置为两组,两组容置空间1012之间通过连接壁10124连接,每组容置空间1012中均设置发光单元2和光学构件3。电源4被设置于两组容置空间1012的第一壁部10121之间。具体的,电源4固定于两组容置空间1012之间的连接壁10124上。且电源4安装于连接壁10124后,可增加连接壁10124的结构强度。如图3E所示,另一实施例中,容置空间1012设置为一组,此时,电源4设置于LED照明设备的长度方向的一端。
本实施例中的灯板201为可挠式电路板或柔性基板。第一壁部10121上设置孔洞10125,灯板201穿过孔洞10125后,与电源4电性连接。一实施例中,灯板201可与电源4直接焊接。一实施例中,灯板201与电源4通过一定位单元定位后再焊接。
本实施例中的光学构件3贴设于安装表面1011。进一步的,本实施例中的光学构件3可直接固定于安装表面1011。一实施例中,光学构件3直接粘接于安装表面1011。一实施例中,光学构件3通过固定结构固定于安装表面1011,如通过螺栓、卡扣等。
本实施例中,光学构件3配置为控制LED照明设备的出光角度及出光均匀性。例如,发 光单元2点亮时射出的光线,经由光学构件3而从LED照明设备射出时,LED照明设备的发光角度控制为80度至130度。进一步的,发光单元2点亮时射出的光线,经由光学构件3而从LED照明设备射出时,LED照明设备的发光角度控制为90度至120度。更进一步的,发光单元2点亮时射出的光线,经由光学构件3而从LED照明设备射出时,LED照明设备的发光角度控制为90度至100度。
参见图3A、图3B及图1G,本实施例中,为控制LED照明设备的出光均匀性,发光单元2点亮时射出的光线,在一第一区域A范围内的照度与在一第二区域B范围内的平均照度的比值大于0.3、0.4、0.5、0.6、0.7、0.8或0.9,而小于2。一些实施例中,在一第一区域A范围内的照度与在一第二区域B范围内的平均照度的比值大于0.5,而小于1.5。一些实施例中,在一第一区域A范围内的照度与在一第二区域B范围内的平均照度的比值大于0.7,而小于1.3。其中,第一区域A与第二区域B位于同一平面上。且第一区域A及第二区域B均位于一第三区域C(第三区域C与第一区域A及第二区域B位于同一平面)内,而第三区域C对应的光束角c为90度、80度、60度或50度。本实施例中的光束角c可小于LED照明设备的发光角度。本实施例中,以光束角50度范围内的照度差异来考量出光均匀性,以此,第三区域C对应的光束角为50度。另外,第一区域A及第二区域B可以为第三区域C内的任意区域。需要注意的是,本处所指的光束角a并非指的有光范围的边界线所形成的夹角。本实施例中的第三区域C的中心或圆心的位置与LED照明设备对应,即LED照明设备沿光轴D投影至第三区域C时,其位置落于或大致落于第三区域C的中心或圆心。本实施例中,第一区域A与第二区域B所在的平面与光轴D垂直或大致垂直。
参见图3A、图3B及图1H,一实施例中,为控制LED照明设备的出光均匀性,发光单元2点亮时射出的光线在一第一区域A范围内的照度与在一第二区域B范围内的平均照度的比值大于0.3、0.4、0.5、0.6、0.7、0.8或0.9,而小于2。一些实施例中,在一第一区域A范围内的照度与在一第二区域B范围内的平均照度的比值大于0.5,而小于1.5。一些实施例中,在一第一区域A范围内的照度与在一第二区域B范围内的平均照度的比值大于0.7,而小于1.3。其中,第一区域A与第二区域B位于同一平面上,且同心或大致同心设置(假设各区域为圆形或大致的圆形,其中心或圆心位于相同位置)。且第一区域A及第二区域B均位于一第三区域C(第三区域C与第一区域A及第二区域B位于同一平面)内,而第三区域C对应的光束角c为90度、80度、60度或50度。本实施例中的光束角可小于LED照明设备的发光角度。本实施例中,以光束角50度范围内的照度差异来考量出光均匀性,以此,第三区域C对应的光束角c为50度。另外,第一区域A及第二区域B与第三区域C同心或大致同心设置,且第一区域A对应的光束角a和第二区域B对应的光束角b均小于第三区域C对应的光束角c。需要注意的是,本处所指的光束角并非指的有关范围的边界线所形成的夹角。本实施例中的第三区域C的中心或圆心的位置与LED照明设备对应,即LED照明设备沿光轴D投影至第三区域C时,其位置落于或大致落于第三区域C的中心或圆心。本实施例中,第一区域A与第二区域B所在的平面与光轴D垂直或大致垂直。
一实施例中,光学构件3可以是一整体式结构而罩设于发光单元2上。一实施例中,光学构件3为多段式的,即一发光单元2对应设置多组光学构件3。
如图4A至图4B所示,本发明于第四实施例中提供一种LED照明设备,本实施例中的基本结构可同前述实施例。所不同的是,发光单元2的安装方式。具体的,本实施例中的LED照明设备包括光源载体1、发光单元2、光学构件和安装单元6,发光单元2固定于安装单元6上。光源载体1包括底座101,发光单元2面向底座101而设置。本实施例中的发光单元2工作时产生的光线的至少80%经底座101反射后从LED照明设备射出。
进一步的,底座101上设置有光学面1013,以反射发光单元2产生的光线。本实施例中通过底座101反射的方式出光,可使得出光更加均匀,更利于眩光值的控制。
本实施例中的安装单元6具有一第一状态及第二状态,在第一状态时,发光单元2面对底座101而设置,此时,发光单元2和安装单元6超出底座101在LED照明设备的高度(或厚度)方向限定的范围,即发光单元2和安装单元6超出底座101的下端壁10123;在第二状态时,发光单元2及安装单元6收容于底座101的容置空间1012内,且发光单元2或安装单元6均不超过底座101在LED照明设备的高度(或厚度)方向限定的范围,即发光单元2和安装单元6不超出底座101的下端壁10123,以降低包装尺寸。
一实施例中的安装单元6可转动的连接在底座101上,且安装单元6转动时,在上述第一状态和第二状态间切换。
一实施例中的安装单元6可沿底座101高度(厚度)方向滑动的连接在底座101上,以其相对底座101的位置的不同而在第一状态和第二状态间切换。
上述实施例中,在第一状态和/或第二状态时,还可设置一锁定单元来进行定位,以使安装单元保持在第一状态或第二状态。
本实施例中同样还可设置一光学构件,以使本实施例中的LED灯具具有较好的出光效果。
如图5A至图5B所示,本发明于第五实施例中提供一种LED照明设备,本实施例中的基本结构可同前述实施例。所不同的是,本实施例中的光学构件3为一光学罩。光学罩涂覆扩散层或者光学罩以其自身的材料属性而具有扩散功能,以降低眩光,使得出光更均匀。
如图6A至图6P所示,本发明于第六实施例中提供一种LED照明设备,本实施例中的LED照明设备的基本结构可同前述的第三实施例。本实施例中的LED照明设备包括光源载体1、发光单元2、光学构件3及电源4。其中,发光单元2固定于光源载体1上,光学构件3罩设于或至少部分罩设于发光单元2上,以使发光单元2点亮时,其所发出的光的至少一部分或全部经光学构件3而从LED照明设备射出。一实施例中,发光单元2点亮时,其所发出的光通量的至少80%经光学构件3而直接从LED照明设备射出(不经底座101等的反射)。一实施例中,发光单元2点亮时,其所发出的光通量的至少90%经光学构件3而直接从LED照明设备射出(不经底座101等的反射)。本实施例中的发光单元2以不可拆卸的形式(不可替换)固定于光源载体上(因此可称之为一体式照明设备)。
参见图6A至6F,本实施例中的光源载体1包括底座101(不包括前述可拆卸的端盖)。 底座101限定一安装表面,发光单元2直接或间接的固定于所述安装表面。进一步的,发光单元2包括灯板201及发光体202,发光体202固定于灯板201上,发光体202可以为LED灯珠。本实施例中,灯板201贴设于安装表面,如灯板201采用胶而粘接于安装表面,或者安装表面设置安装结构,以将灯板201以卡接、扣接、螺纹连接、磁吸等方式贴合于安装表面。本实施例中,灯板201固定于安装表面后,发光单元2与底座101形成导热路径。以此,发光单元2点亮时产生的热量可传导至底座101,并借由底座101进行散热。
本实施例中,底座101上形成容置空间1012,发光单元2和光学构件3均设置于容置空间1012内,且在底座101高度方向上,发光单元2和光学构件3均不超过容置空间1012限定的范围(LED照明设备的高度方向上,容置空间1012所限定的范围)。本实施例中的容置空间1012可设置两组,以对应设置两组发光单元2及光学构件3。
本实施例中的底座101包括第一壁1014、第二壁1015及安装壁1016,所述发光单元2的灯板201至少部分或全部固定于所述安装壁1016上。一实施例中,灯板201宽度方向的一部分贴覆于安装壁1016上(确保配置发光体202部分的灯板201贴覆于安装壁1016),而灯板201宽度方向的两侧则贴覆于第一壁1014和第二壁1015上。本实施例中的第一壁1014和第二壁1015均可为平面,且当LED照明设备水平安装后,第一壁1014和第二壁1015分别与水平面呈一夹角。本实施例中的安装壁1016的设置,可利于发光单元2的安装,使得灯板201安装于安装壁1016后,发光体202可提供向下发光。安装壁1016上可设置一用于安装灯板201的平面。本实施例中的贴覆可以为大致的贴覆,即灯板201的背面的30%以上面积贴合在安装壁1016上。本实施例中的贴覆可以指的是灯板201通过其他介质(例如胶)而贴覆在安装壁1016。
本实施例中的底座101还包括端壁1017,所述端壁1017设于第一壁1014及第二壁1015的端部,且同时与第一壁1014及第二壁1015连接。第一壁1014、第二壁1015、安装壁1016及端壁1017限定所述容置空间1012的结构及容置空间1012限定的范围。端壁1017、第一壁1014及第二壁1015的设置,可确保底座101的结构强度。其中,端壁1017的设置,可在省略端盖的前提下,确保LED照明设备的结构强度。
本实施例中的LED照明设备仅包括一光学构件3(一发光单元2仅配置一光学构件3,在设置多组发光单元2时,每组发光单元2仅对应配置一组光学构件3)。本实施例由于仅设置一光学构件3,因此,可减小因设置光学构件时造成的光损。本实施例中的LED照明设备仅包括一光学构件3时,LED照明设备的出光率(出光率指的是承诺过LED照明设备射出的光通量与发光单元2产生的光通量的比值)可达到90%、92%、95%以上。本实施例中的光学构件3完全容纳于容置空间1012内,以使其不会占用LED照明设备额外的高度空间。也就是说,光学构件3在LED照明设备的高度方向上不超出底座101限定的空间。本实施例中,发光单元2与光学构件3在LED照明设备的高度方向上至少部分重叠,以降低发光单元2与光学构件3结合后的高度,并且可降低发光单元2与光学构件3之间的间距,以减小光线在该间距内的光损。进一步的,发光单元2在LED照明设备的高度方向上不超出光学构件3所 限定的范围。如图6T所示,底座101可上设置可有固定单元1019,光学构件3通过固定单元1019固定并定位于底座101上。本实施例中,固定单元1019包括一臂部10191,该臂部10191可以一体成型方式形成于底座101上,臂部10191以压紧或扣合的方式将光学构件3固定。装配时,将臂部10191弯折,以固定光学构件3。进一步的,为实现光学构件3在长度方向上的定位,光学构件3上设置定位缺口304,臂部10191卡入该定位缺口304中,以完成对光学构件3的固定和定位。本实施例中,光学构件3上设置多个定位缺口304,以便于与多个臂部10191完成配合,防止光学构件3发生偏转。
本实施例中的光学构件3大体上来讲,仅覆盖灯板201,而不会额外的覆盖底座101的面积。举例来讲,光学构件3覆盖底座101的正面的面积占底座101正面总的面积不超过10%。本实施例中的底座101的正面的面积指的是垂直于灯板201的方向上的投影面积。具体的,底座101的正面的面积为底座101的长度乘以宽度。而光学构件3覆盖底座101的正面的面积为光学构件3投影至底座101所占用的面积,实际上,该面积为光学构件的长度乘以宽度。本实施例中,光学构件3为提供对灯板201的覆盖,且不至于覆盖过多的底座101的正面的面积,设置光学构件3的宽度与灯板201的宽度的比值为1.1~2之间。进一步的,设置光学构件3的宽度与灯板201的宽度的比值为1.1~1.5之间。
参见图6C和图6D,本实施例中,光学构件3包括第一配光单元3001及第二配光单元3002。本实施例中的第一配光单元3001配置为条状,且沿第一配光单元3001的长度方向设置一容置槽30011,发光单元2在高度方向上的至少一部分位于容置槽30011内。第二配光单元3002设置于第一配光单元3001的表面,且第二配光单元3002与容置槽30011在光学构件3的高度方向上分别位于第一配光单元3001的相对的两侧。发光单元2的发光体202与第二配光单元3002对应配置。具体的,发光体202与第二配光单元3002一一对应配置。
进一步的,发光单元2的发光体202完全容纳于容置槽30011内。本实施例中的发光体202表面至容置槽30011的底面(容置槽30011对应于发光体202的表面)的距离为A(A大于等于0),发光体202表面至第二配光单元3002的距离为B,A与B的关系满足以下条件:A:B的值大于0.05且小于0.25。进一步的,A与B的关系满足以下条件:A:B的值大于0.1且小于0.2。当A和B满足以上关系时,可控制发光体202发出的光可大部分或完全对应于第二配光单元3002,。也就是说,不考虑发光体202产生的光在界面处的反射的话,发光体202产生光将完全投射至第二配光单元3002,并由第二配光单元3002做光学处理。
本实施例中的灯板201配置于容置槽30011内,且灯板201两侧对应于容置槽30011的内侧壁。灯板201侧部可接触容置槽30011的内侧壁。也就是说,容置槽30011的内侧壁对灯板201起到限位作用,以确定灯板201上的发光体202的位置,使发光体202与光学构件3(第二配光单元3002)对准。
在一实施例中,发光体202的表面可直接接触容置槽30011的底面(图未示)。以此,发光体202产生的光线可直接进入第一配光单元3001的介质中,而不会先经过发光体202与第一配光单元3001之间的空气,因此,可减少光线经过的界面(具有不同折射率的界面),从 而降低光损。另外,发光体202的表面直接接触容置槽30011的底面,发光体202产生的热可传导至第一配光单元3001,可利于发光体202的散热。在一实施例中,发光体202的表面通过一光学介质而接触容置槽30011的底面(图未示),也就是说,发光体202的表面通过光学介质而直接接触容置槽30011的底面,以此排除发光体202表面至容置槽30011的底面之间的间隙内的空气,做到更好的折射率匹配。其他实施例中,发光体202表面设置光学介质,以达到更好的出光效果,且该光学介质与容置槽30011的底面不接触。
本实施例中的发光体202产生的光通量的至少70%经由第二配光单元3002而从LED照明设备直接射出。其余的光通量则由第一配光单元3001射出。进一步的,发光体202产生的光通量的至少80%经由第二配光单元3002而从LED照明设备直接射出。更进一步的,发光体202产生的光通量的至少90%经由第二配光单元3002而从LED照明设备直接射出。经由第一配光单元3001射出的光线的至少一部分射至底座101的表面上,以使底座101处呈现更佳的光学效果。
本实施例中的容置槽30011的底面形成入光部30012,发光体202产生的光线的至少一部分(例如发光体202产生的光通量的至少80%,或者发光体202产生的光通量的至少90%)透过入光部30012而进入光学构件3,并进入第二配光单元3002。在一实施例中,在不考虑入光部30012处的反射的情况下,发光体202产生的光通量全部直接进入入光部30012,也就是说,发光体202的出光范围完全对应于入光部30012内,以提高出光效果(出光效率及出光光型)。本实施例中的第二配光部3002包括第一出光部30021及第二出光部30022。第一出光部30021及第二出光部30022的表面的照度比值大于0.3、0.4、0.5、0.6、0.7、0.8或0.9,且小于2、1.9、1.8、1.7、1.6或1.5,以使在LED照明设备的出光范围内的出光更加均匀。本实施例中,第一出光部30021包括一平面或大致的平面,第二出光部30022包括一锥面或大致的锥面,第二出光部30022围绕第一出光部30021而设置。
本实施例中,第二出光部30022的表面积与第一出光部30021的表面积的比值大于20。进一步的,第二出光部30022的表面积与第一出光部30021的表面积的比值大于30。以此可获得较佳的出光效果(出光角度和光型)。本实施例中的第二出光部30022的高度H小于2mm,且大于0.5mm。进一步的,第二出光部30022的高度H小于1.5mm,且大于0.8mm,以控制出光时的光分布。
如图6T所示,第二出光部30022的表面积与第一出光部30021的表面积的比值可设置为大于0.7,且小于1.8。进一步的,第二出光部30022的表面积与第一出光部30021的表面积的比值可设置为大于0.8,且小于1.5。以此可获得较佳的出光效果(出光角度和光型),此时,LED照明设备在一出光区域内可获得更佳的出光均匀性。并且,相应的,第二出光部30022的高度H小于0.8mm,且大于0.2mm。进一步的,第二出光部30022的高度H小于0.7mm,且大于0.3mm。以控制出光时的光分布。
如图6D所示,本实施例中的第二出光部30022具有一轮廓线,该轮廓线沿第二配光部3002的中轴线回转360度而形成第二出光部3002的外轮廓。本实施例中的第二出光部30022 的锥面的外轮廓的轮廓线的斜率的绝对值为0.3~0.8之间。进一步的,第二出光部30022的锥面的外轮廓的斜率的绝对值为0.35~0.5之间。第二出光部30022起到调整光型的作用,当第二出光部30022的锥面的外轮廓的轮廓线的斜率的绝对值在上述区间时,可获得较佳的出光效果(出光角度及出光光型)。本实施例中,计算第二出光部30022的锥面的外轮廓的轮廓线的斜率时,以图6D的放置方式来计算,即光学构件3位于发光单元2的上方。
如图6T所示,在一实施例中的第二出光部30022具有一轮廓线,该轮廓线沿第二配光部3002的中轴线回转360度而形成第二出光部3002的外轮廓。本实施例中的第二出光部30022的锥面的外轮廓的轮廓线的斜率的绝对值为0.25~0.6之间。进一步的,第二出光部30022的锥面的外轮廓的斜率的绝对值为0.3~0.6之间。更进一步的,第二出光部30022的锥面的外轮廓的斜率的绝对值为0.4~0.5之间。第二出光部30022起到调整光型的作用,当第二出光部30022的锥面的外轮廓的轮廓线的斜率的绝对值在上述区间时,可获得较佳的出光效果(出光角度及出光光型)。本实施例中,计算第二出光部30022的锥面的外轮廓的轮廓线的斜率时,以图6D的放置方式来计算,即光学构件3位于发光单元2的上方。
本实施例中LED照明设备,从出光路径上来讲,发光体202工作时产生的光通量的至少80%、85%或90%,经第二配光单元3002而直接从LED照明设备射出(该部分光经第二配光单元3002后,不经底座101的反射,以降低反射时可能的光损),从而可提高出光效率。本实施例中,发光体202产生的光线的一部分(小于总光通量的20%、15%、或10%)透过第一配光单元3001而射至底座101上,并通过底座101的反射而直接从LED照明设备射出,无需通过现有技术中的透光板或扩散板等进行出光。总体上讲,本实施例中的LED照明设备所射出的光中,经底座101反射而射出的光小于经第二配光单元3002而射出的光,通过减少依靠反射的出光,可降低光损,提高出光效率。本实施例中,可将通过底座101反射的出光控制在总的出光的光通量的10%以下,而90%以上的出光则通过反射而直接出光,以降低反射时造成的光损。
其他实施例中,第二配光单元3002可采用球面结构或多边形棱镜结构。
参见图6A、图6B及图1G,本实施例中,为控制LED照明设备的出光均匀性,发光单元2点亮时射出的光线,在一第一区域A范围内的照度与在一第二区域B范围内的平均照度的比值大于0.3、0.4、0.5、0.6、0.7、0.8或0.9,而小于2。一些实施例中,在一第一区域A范围内的照度与在一第二区域B范围内的平均照度的比值大于0.5,而小于1.5。一些实施例中,在一第一区域A范围内的照度与在一第二区域B范围内的平均照度的比值大于0.7,而小于1.3。其中,第一区域A与第二区域B位于同一平面上。且第一区域A及第二区域B均位于一第三区域C(第三区域C与第一区域A及第二区域B位于同一平面)内,而第三区域C对应的光束角c为90度、80度、60度或50度。本实施例中的光束角c可小于LED照明设备的发光角度。本实施例中,以光束角50度范围内的照度差异来考量出光均匀性,以此,第三区域C对应的光束角为50度。另外,第一区域A及第二区域B可以为第三区域C内的任意区域。需要注意的是,本处所指的光束角a并非指的有光范围的边界线所形成的夹角。 本实施例中的第三区域C的中心或圆心的位置与LED照明设备对应,即LED照明设备沿光轴D投影至第三区域C时,其位置落于或大致落于第三区域C的中心或圆心。本实施例中,第一区域A与第二区域B所在的平面与光轴D垂直或大致垂直。
参见图6A、图6B及图1H,一实施例中,为控制LED照明设备的出光均匀性,发光单元2点亮时射出的光线,在一第一区域A范围内的照度与在一第二区域B范围内的平均照度的比值大于0.3、0.4、0.5、0.6、0.7、0.8或0.9,而小于2。一些实施例中,在一第一区域A范围内的照度与在一第二区域B范围内的平均照度的比值大于0.5,而小于1.5。一些实施例中,在一第一区域A范围内的照度与在一第二区域B范围内的平均照度的比值大于0.7,而小于1.3。其中,第一区域A与第二区域B位于同一平面上,且同心或大致同心设置(假设各区域为圆形或大致的圆形,其中心或圆心位于相同位置)。且第一区域A及第二区域B均位于一第三区域C(第三区域C与第一区域A及第二区域B位于同一平面)内,而第三区域C对应的光束角c为90度、80度、60度或50度。本实施例中的光束角可小于LED照明设备的发光角度。本实施例中,以光束角50度范围内的照度差异来考量出光均匀性,以此,第三区域C对应的光束角c为50度。另外,第一区域A及第二区域B与第三区域C同心或大致同心设置,且第一区域A对应的光束角a和第二区域B对应的光束角b均小于第三区域C对应的光束角c。需要注意的是,本处所指的光束角并非指的有关范围的边界线所形成的夹角。本实施例中的第三区域C的中心或圆心的位置与LED照明设备对应,即LED照明设备沿光轴D投影至第三区域C时,其位置落于或大致落于第三区域C的中心或圆心。本实施例中,第一区域A与第二区域B所在的平面与光轴D垂直或大致垂直。
本实施例中LED照明设备的总体高度控制在30mm以下。进一步的,LED照明设备的总体高度控制在25mm以下。也就是说,发光单元2在LED照明设备的高度控制在30mm或25mm以下时,在仅有的可用作调光的空间内,可达到上述的出光效果。
一实施例中,光学构件3可以是一整体式结构而罩设于发光单元2上。一实施例中,光学构件3为多段式的,即一发光单元2对应设置多组光学构件3。
参见图6R,一实施例中,至少部分发光体202相对与其对应的第二配光单元3002而偏向该第二配光单元3002的一侧(光学构件3长度方向的一侧)。至少部分发光体202相对与其对应的第二配光单元3002而偏向该第二配光单元3002的另一侧(光学构件3长度方向的另一侧)。以此,可降低发光体202与第二配光单元3002出现偏差时的影响。本实施例中,任意一发光体202对与其对应的第二配光单元3002的偏差小于1mm(在光学构件3长度方向上,发光体202的中心至第二配光单元3002的中轴线的距离)。
本实施例中,为降低发光体202与第二配光单元3002的偏差,可设置定位结构。一实施例中,在第一配光单元3001上设置若干个固定槽(图未示),通过固定槽来固定发光体202,并将发光体202的位置固定,从而使发光体202与第二配光单元3002精确对准。其他实施例中,可将灯板201与光学构件3做定位(图未示),例如在光学构件3上设置定位柱,而在灯板201上设置定位孔。
一实施例中,可先将光学构件3与发光单元2固定为一体后,再将其整体安装至底座101上(图未示)。一实施例中,光学构件3与发光体202固定后,再将其与灯板201固定,此时灯板201可先固定至底座101,也可与前述的光学构件3及发光体202固定后,再固定至底座101(图未示)。
参见图6A至图6C及图6F至图6K,本实施例中的底座101上设置有通孔10171。进一步的,通孔10171可设置于端壁1017上,且通孔10171位于安装壁1016在其长度方向的延伸方向上。本实施例中的灯板201为可挠式电路板或柔性电路板,且灯板201穿过通孔10171而到达底座101的背面(底座101相对发光单元2的另一面)。本实施例中的灯板201沿底座101背面延伸并贴覆在底座101背面的一侧的端面1018(底座101在发光单元2长度方向的第一端的背面),电源4设置于端面1018上,并与灯板201电气连接。本实施例中的电源4在LED照明设备的高度方向上不超过底座101所限定的范围,以使电源不会额外占用LED照明设备高度空间,并且包装运输时不易碰撞到电源4而造成电源4损坏。
本实施例的LED照明设备,由于其光学构件3的具体设置(高度、位置、结构等设置)及电源4的设置(高度、位置、结构等设置),可使LED照明设备的总体高度控制在30mm以下。进一步的,LED照明设备的总体高度控制在25mm以下。
参见图6G及图6J至图6P,本实施例中的电源4包括电源盒41、电子元件42及电源板45,电子元件42设于电源板45上,电源盒41固定于底座101上。本实施例中,电源4进一步包括电隔离管43,所述电子元件42及电源板45全部或至少部分设于电隔离管43内,而电隔离管43设于电源盒41内,电隔离管43为绝缘材质制成,起到电隔离作用,可降低触电风险。本实施例中的电源盒41具有一开口411,电隔离管43透过该开口411而装入电源盒41内。电源盒41具有开口411的一侧对应于底座101的端面1018,从而将电源盒41封闭,以此可方便安装,并节约材料成本。本实施例中,电子元件42隔在电源板45及底座101背面的端面1018之间,以使电源板45及底座101背面的端面1018保持间距。
本实施例中的电源盒41具有第一腔4101及第二腔4102,其中,电隔离管43及电子元件42设于第一腔4101内,且电隔离管43设于第一腔4101内后,可增加其所在位置的电源盒41的强度。而第二腔4102处设置接线板44,接线板44将第二腔4102封闭。本实施例中的电源4通过导线与接线板44电连接。具体的,导线一端在第一腔4101内与电源4的电源板45电连接,而导线的另一端进入第二腔4102与接线板44电连接。
本实施例中的电隔离管43压住灯板201,以使灯板201贴覆于底座101背面的端面1018,以防止灯板201松动,且电子元件42与灯板201之间通过电隔离管43而隔开,从而起到防触电作用。本实施例中,电源盒41可至少部分压住灯板201。灯板201的一端直接焊接至电源板45上。其他实施例中,灯板201通过一定位单元与电源板45定位后,再通过焊接的方式实现连接。定位单元可以为定位柱,该定位柱可同时穿过电源板45及灯板201,从而对电源板45及灯板201实现定位,以方便安装及确保电连接的准确性。
参见图6K及图6M,本实施例中,灯板201为可挠式电路板为柔性灯板,并具有一弯折 部2011,灯板201在弯折部2011处实现翻折,以使灯板201在弯折部2011之后部分的正面(具有发光体202的表面)背向底座101的背面的端面1018而设置,以利于该部分灯板201与电源板45实现连接。
参见图6I,6K及图6M,本实施例中的LED照明设备进一步包括一遮挡部7。灯板201穿过通孔10171后在底座101的背面具有第一部分及第二部分,第二部分贴合于底座101背面的端面1018上,而第一部分则用于连接第二部分及位于底座101正面部分的灯板201,遮挡部7罩设于灯板201的第一部分上,以使第一部分不外露,以防止外界接触到灯板201的第一部分而触电。
参见图6U和图6V,本实施例中的灯板201还可采用硬灯板,如采用铝基板或FR4板。此时,灯板201两端可不延伸至底座101的背面而与电源4(图未示)直接连接,而是通过导线连接灯板201与电源4。此时,遮挡部7遮挡露于外部的导线上,以使该部分的导线不外露。
本实施例中的发光体202包括第一发光体和第二发光体(图未示),第一发光体和第二发光体点亮时具有不同的色温、光通量或显色指数。以此可为LED照明设备调光提供基础。本实施例中的发光单元2具有两列发光体202(图未示),其中一列为第一发光体,而另一列为第二发光体。与之对应的光学构件3具有两列第二配光单元3002(图未示),以对应第一发光体和第二发光体。
参见图6V和图6W,本实施例中的电源盒41固定于底座101背面的端面1018,并且电源盒41与端面1018保持间距,以减小底座101与电源盒41之间的热传导。本实施例中的电源盒41上设置有第一固定单元412,而底座101上设置有第二固定单元1019,电源盒41通过第一固定单元412及第二固定单元1019的配合而固定至底座101上。具体的,第一固定单元412可包括安装孔和/或扣合部,而第二固定单元1019可包括与第一固定单元412配合的扣合件和/或安装孔。
本实施例中的底座101具有两组安装壁1016,且两组安装壁1016处对应设置发光单元2,电源盒41在长度方向上的两端分别超出两组安装壁1016,以增加底座101在该方向上的结构强度。本实施例中,电源盒41在长度方向上占底座101的40%以上。进一步的,电源盒41在长度方向上占底座101的50%以上,且不超过底座101的60%。本实施例中,电源盒41的第二腔4102在其长度方向上跨过(对应)至少一个完整的安装壁1016,也就是说,安装壁1016在其长度方向上的投影,完全落入电源盒41的第二腔4102所在的范围。本实施例中,安装壁1016所在位置具有折弯结构(安装壁1016分别与第一壁1014及第二壁1015之间具有折弯结构),其结构强度较高,而将第二腔4102设置为与安装壁1016对应,可防止底座101在该处变形而使第二腔4102所在位置的电源盒41发生变形,提高结构强度及可靠性。
本实施例中的遮挡部7具有一止挡部71,该止挡部71延伸至底座101背面的端面1018上,电源盒41架设于该止挡部71上,并与底座101背面的端面1018保持间距。电源盒41上可设置定位槽415,定位槽415与遮挡部7的止挡部71定位配合,以此可定位电源盒41 的位置。
本实施例中的遮挡部7一扣合的方式固定于底座101上。具体的,遮挡部7的一端卡入通孔10171中,而遮挡部7的另一端则与底座101实现配合。例如,底座101上设置扣合臂,以扣在遮挡部7的另一端的表面。
参见图6X和图6Y,本实施例中的接线盒41上设置有第一固定孔413及第二固定孔414。接线板44一端设置有卡入所述固定孔413的固定壁441,而接线板44的相对的另一端设置弯折壁442,该弯折壁442从接线盒41的外侧而卡入第二固定孔414内,从而实现接线板44的固定。
参见图6G,本实施例中的底座101的背面的外缘设置有安装件8,以用于进行安装,如将LED照明设备以挂置的方式安装至外部。
参见图6Z,本实施例中的安装件8包括第一部分81及、第二部分82及主体部83,第一部分81连接于底座101上,具体的,可连接至底座101的加强结构9处。第一部分81可包括一挂钩,从而挂于底座101上,并且第一部分81相对底座101的方向和位置可调。第二部分82配置为用于与外部结构连接。第二部分82包括一挂钩,第二部分82与外部结构连接时,采用挂置的方式进行连接。本实施例中的主体部83具有可弯折性,安装时,可弯折主体部83,从而便于与外部结构实现连接。
本实施例中的底座101的背面的外缘设置有加强结构9。一实施例中,底座101的外缘处翻折而形成所述加强结构9。该加强结构9可贴合于底座101背面的端面1018,或者该加强结构9可垂直于底座101背面的端面1018。一实施例中,在外缘处设置加强筋而形成所述加强结构9。一实施例中,在外缘处安装加强肋条而形成所述加强结构9。
本实施例中,电源4完全容置于底座101的高度方向上的下端面及上端面限定的范围内。因此,电源4不会额外占用LED照明设备的高度空间。因此,LED照明设备的高度与底座的高度相同。
本实施例中,为整体上控制LED照明设备的高度尺寸,电源盒41的高度占LED照明设备的整体的高度尺寸的占比达到80%以上。在电源盒41为标准件或者电源盒41要确保安装电源板45及电子元件42等部件的空间时,电源盒41的高度占LED照明设备的整体的高度尺寸的占比越高,其空间利用率越高,越利于整灯的高度的控制。进一步的,电源盒41的高度占LED照明设备的整体的高度尺寸的占比达到90%以上。更进一步的,电源盒41的高度占LED照明设备的整体的高度尺寸的占比达到95%以上。
本实施例中,电源盒41配置于加强结构9与端壁1017之间(加强结构9与端壁1017之间形成容置空间,以用于放置电源4,以使电源4不会占用额外空间),其中,电源盒41至少一侧与加强结构9连接,以对加强结构9起到进一步加强的作用。电源盒41的一侧分别与两组端壁1017连接,从而增加底座101在电源盒41长度方向上的强度。
如图7A至图7E所示,本发明于第七实施例中提供一种LED照明设备,本实施例中的LED照明设备的基本结构可同前述的第六实施例。本实施例中的LED照明设备包括光源载体 1、发光单元2、光学构件3及电源4。其中,发光单元2固定于光源载体1上,光学构件3罩设于或至少部分罩设于发光单元2上,以使发光单元2点亮时,其所发出的光的至少一部分或全部经光学构件3而从LED照明设备射出。一实施例中,发光单元2点亮时,其所发出的光通量的至少80%经光学构件3而直接从LED照明设备射出(不经底座101等的反射)。一实施例中,发光单元2点亮时,其所发出的光通量的至少90%经光学构件3而直接从LED照明设备射出(不经底座101等的反射)。本实施例中的发光单元2以不可拆卸的形式(不可替换)固定于光源载体上(因此可称之为一体式照明设备)。
参见图7A至7E,本实施例中的光源载体1包括底座101(不包括前述可拆卸的端盖)。底座101限定一安装表面,发光单元2直接或间接的固定于所述安装表面。进一步的,发光单元2包括灯板201及发光体202,发光体202固定于灯板201上,发光体202可以为LED灯珠。本实施例中,灯板201贴设于安装表面,如灯板201采用胶而粘接于安装表面,或者安装表面设置安装结构,以将灯板201以卡接、扣接、螺纹连接、磁吸等方式贴合于安装表面。本实施例中,灯板201固定于安装表面后,发光单元2与底座101形成导热路径。以此,发光单元2点亮时产生的热量可传导至底座101,并借由底座101进行散热。
本实施例中,底座101上形成容置空间1012,发光单元2和光学构件3均设置于容置空间1012内,且在底座101高度方向上,发光单元2和光学构件3均不超过容置空间1012限定的范围(LED照明设备的高度方向上,容置空间1012所限定的范围)。本实施例中的容置空间1012可设置多组,以对应设置多组发光单元2及光学构件3。如图7F所示,一实施例中,容置空间1012设置一组。一实施例中,容置空间1012设置两组,且这两组容置空间1012沿同一方向延伸设置。如图7G所示,一实施例中,容置空间1012设置有四组,其中两组容置空间1012沿一第一方向X延伸设置,另外两组容置空间1012沿一第二方向Y,第一方向X与第二方向Y垂直或大致垂直设置,此时,容置空间1012呈环状,四组光学构件3设置于容置空间1012内时,四组光学构件3以此对应配置,且呈环状(例如呈“口”字型)。
如图7A至图7D所示,本实施例中的底座101包括第一壁1014、第二壁1015及安装壁1016,所述发光单元2的灯板201全部固定于所述安装壁1016上。一实施例中,灯板201宽度方向完全贴覆于安装壁1016上,即灯板201宽度方向的两侧不会贴覆至第一壁1014或第二壁1015上。本实施例中的第一壁1014和第二壁1015均可为平面,且当LED照明设备水平安装后,第一壁1014和第二壁1015分别与水平面呈一夹角。本实施例中的安装壁1016的设置,可利于发光单元2的安装,使得灯板201安装于安装壁1016后,发光体202可提供向下发光。本实施例中的贴覆可以为大致的贴覆,即灯板201的背面的30%以上面积贴合在安装壁1016上。本实施例中的贴覆可以指的是灯板201通过其他介质(例如胶)而贴覆在安装壁1016。举例来讲,灯板201的背面30%以上面积通过胶而贴覆在安装壁1016,即可算为灯板201贴覆在安装壁1016。本实施例中的容置空间1012由第一壁1014、第二壁1015及安装壁1016共同构成。
本实施例中的第一壁1014和第二壁1015分别配置于发光单元2和光学构件3的两侧, 发光单元2点亮时产生的光学,通过光学构件3后射出,该射出的光学的至少一部分经第一壁1014和第二壁1015的反射后从LED照明设备射出。也就是说,第一壁1014和第二壁1015对光线起到重定向的作用,以调整LED照明设备的出光范围及出光时的光分布,以得到较好的光学效果。
本实施例中的多组第一壁1014依次连接,并在底座101的背面形成一凹腔。本实施例中,多组(如四组)第一壁1014构成凹腔的四壁,另外配置一基底,则共同构成了所述凹腔。电源4容置与该凹腔内。一实施例中,电源4高度方向上的至少80%位于该凹腔内。一实施例中,电源4高度方向上的完全位于该凹腔内。以此,可减小电源4占用LED照明设备高度方向上的空间,甚至使得电源4完全不占用LED照明设备高度方向上的空间(底座101的高度等于或大致等于LED照明设备的高度)。
本实施例中的LED照明设备仅包括一光学构件3(一发光单元2仅配置一光学构件3,在设置多组发光单元2时,每组发光单元2仅对应配置一组光学构件3)。光线通过介质时,均会有光损。而本实施例由于仅设置一光学构件3,因此,可减小因设置光学构件时造成的光损,提高出光效率。本实施例中的LED照明设备仅包括一光学构件3时,LED照明设备的出光率(出光率指的是指LED照明设备射出的光通量与发光单元2产生的光通量的比值)可达到90%、92%、95%以上。本实施例中的光学构件3完全容纳于容置空间1012内,以使其不会占用LED照明设备额外的高度空间。也就是说,光学构件3在LED照明设备的高度方向上不超出底座101限定的空间。本实施例中,发光单元2与光学构件3在LED照明设备的高度方向上至少部分重叠,以降低发光单元2与光学构件3结合后的高度,并且可降低发光单元2与光学构件3之间的间距,以减小光线在该间距内的光损。进一步的,发光单元2在LED照明设备的高度方向上不超出光学构件3所限定的范围。
本实施例中的光学构件3覆盖底座101的正面的面积占底座101正面总的面积不超过50%,以节省光学构件3的材料成本,且LED照明设备重量将会降低。本实施例中的底座101的正面的面积指的是垂直于灯板201的方向上的投影面积。具体的,底座101的正面的面积为底座101的长度乘以宽度。而光学构件3覆盖底座101的正面的面积为光学构件3投影至底座101所占用的面积,实际上,该面积为光学构件的长度乘以宽度。本实施例中,光学构件3覆盖底座101的正面的面积占底座101正面总的面积超过20%,以防止光线从面积较小的光学构件3射出,而造成局部的强光。
参见图7A至图7D,本实施例中,光学构件3包括第一光学单元3003及第二光学单元3004。以用于满足出光的均匀性(如前述实施例中的出光均匀性的描述)及防眩光的要求。
本实施例中的第一光学单元3003配置为具有光透过或光扩散的功能。本实施例中的第一光学单元3003可采用透明材质,以使其具有光透过的功能。本实施例中的第一光学单元3003的表面为平坦或大致平坦的表面。本实施例中的第一光学单元3003可包括扩散层,以使其具有光扩散的功能,使得出光更加均匀。另外,第一光学单元3003也可因其自身的材料特性而具有光扩散功能,例如第一光学单元3003采用乳白色的材质(如PC)。本实施例中的第一光 学单元3003对应于发光单元2的正面。在LED照明设备的高度方向上,发光单元2投影至第一光学单元3003所在面时,发光单元2的投影完全落入第一光学单元3003的范围内。本实施例中,发光单元2工作时产生的光通量的至少50%经第一光学单元3003进行光处理后直接从LED照明设备射出。
本实施例中的第二光学单元3004配置为将光学单元2工作时射至第二光学单元3004的光线中的至少一部分重新定向。本实施例中,发光单元2产生的光通量中的一部分被射至第一壁1014和第二壁1015上,而设置所述第二光学单元3004时发光单元2射至第一壁1014和第二壁1015上的光通量小于不设置所述第二光学单元3004时射至第一壁1014和第二壁1015上的光通量。以此,通过第二光学单元3004的设置,可减少设置第一壁1014或第二壁1015上的光通量,以减少通过第一壁1014或第二壁1015反射而造成的光损。另外,由于第二光学单元3004的设置,可减小LED照明设备的眩光。
本实施例中,第一光学单元3003的外侧设置所述第二光学单元3004,以减小LED照明设备的眩光。本实施例中,第一光学单元3003的两侧均设置所述第二光学单元3004。本实施例中,第一光学单元3003与第二光学单元3004通过一体式结构构成。例如,光学构件3采用塑料材质,其通过挤塑工艺一体成型,并形成所述第一光学单元3003及第二光学单元3004。
本实施例中,第二光学单元3004包括入射面30041及出射部30042。其中入射面30041配置为大致平坦的表面。一实施例中,入射面30041配置为平直的表面。一实施例中,入射面30041配置为弧面。一实施例中,入射面30041配置为平直的表面与弧面的结合。为减小入射面30041处的发射,还可在入射面30041处设置光学元件,以减小上述的反射。例如可在入射面30041处设置增透膜。
本实施例中的出射部30042包括若干重定向结构30043,以用于限定出光角度,从而降低眩光。本实施例中的重定向结构30043的材质可同第一光学单元3003。并且重定向结构30043的折射率不小于第一光学单元3003的折射率。同一出射部30042上的重定向结构30043的配置方向均不相同。
本实施例中的重定向结构30043的截面形状配置为三角形或大致的三角形结构。
如图8A至图8C所示,本发明于第八实施例中提供一种LED照明设备,本实施例中的LED照明设备的基本结构可同前述的第六实施例。本实施例中的LED照明设备包括光源载体1、发光单元2、光学构件3及电源4。其中,发光单元2固定于光源载体1上,光学构件3罩设于或至少部分罩设于发光单元2上,以使发光单元2点亮时,其所发出的光的至少一部分或全部经光学构件3而从LED照明设备射出。一实施例中,发光单元2点亮时,其所发出的光通量的至少70%经光学构件3而直接从LED照明设备射出(不经底座101等的反射)。一实施例中,发光单元2点亮时,其所发出的光通量的至少5%经过底座101的反射后射出,以使底座101被照亮,提升视觉效果。本实施例中的发光单元2以不可拆卸的形式(不可替换)固定于光源载体1上(因此可称之为一体式照明设备)。
参见图8A至8D,本实施例中的光源载体1包括底座101(不包括前述可拆卸的端盖),且底座101为一体式结构构成。底座101限定一安装表面111,发光单元2直接或间接的固定于所述安装表面111。进一步的,发光单元2包括灯板201及发光体202,发光体202固定于灯板201上,发光体202可以为LED灯珠。本实施例中,灯板201贴设于安装表面111,如灯板201采用胶而粘接于安装表面111,或者安装表面111设置安装结构,以将灯板201以卡接、扣接、螺纹连接、磁吸等方式贴合于安装表面。本实施例中,灯板201固定于安装表面111后,发光单元2与底座101形成导热路径。以此,发光单元2点亮时产生的热量可传导至底座101,并借由底座101进行散热。
本实施例中,由于底座101呈斜面设置,使得底座101上得以形成容置空间1012,发光单元2和光学构件3均设置于容置空间1012内,且在底座101高度方向上,发光单元2和光学构件3均不超过容置空间1012限定的范围(LED照明设备的高度/厚度方向上,容置空间1012所限定的范围)。本实施例中的容置空间1012可设置多组,以对应设置多组发光单元2及光学构件3。一实施例中,容置空间1012设置两组,且这两组容置空间1012沿同一方向延伸设置。
如图8A至图8E所示,本实施例中的底座101包括呈倾斜设置的第一壁1014和第二壁1015,第一壁1014和第二壁1015可反射发光单元2工作时产生的至少一部分光。具体的,第一壁1014配置为用于反射其中一组发光单元2工作时产生的光(大致上讲,第一壁1014仅反射与之对应的反光单元2工作时产生的光),而第二壁1015配置为用于反射另一组发光单元2工作时产生的光(大致上讲,第二壁1015仅反射与之对应的反光单元2工作时产生的光)。
本实施例中的底座101上可弯曲成型一凸部1010,凸部1010具有第一侧面10101及第二侧面10102,其中,第一侧面10101与第一壁1014间形成其中一组容置空间1012,第二侧面10102与第二壁1015间形成另一组容置空间1012。本实施例中的凸部1010还具有连接面10103,第一侧面10101与第二侧面10102通过连接面10103连接。发光单元2及光学构件3设于容置空间1012后,发光单元2及光学构件3在LED照明设备的正面(具有发光单元2的一侧)均不超过连接面10103限定的位置。
本实施例中的第一侧面10101与第二侧面10102于LED照明设备的背面(不具有发光单元2的一侧)形成电源容置槽10104,电源4设置于电源容置槽10104。且电源4在LED照明设备高度方向上不超过底座101限定的范围(电源容置槽10104限定范围),以此控制整灯的高度。本实施例中,为整体上控制LED照明设备的高度尺寸,电源盒4的高度占LED照明设备的整体的高度尺寸的占比达到80%以上。在电源4的电源盒41为标准件或者电源盒41要确保安装电源板及电子元件等部件的空间时,电源盒41的高度占LED照明设备的整体的高度尺寸的占比越高,其空间利用率越高,越利于整灯的高度的控制。
本实施例中的LED照明设备可仅包括一光学构件3(一发光单元2仅配置一光学构件3,在设置多组发光单元2时,每组发光单元2仅对应配置一组光学构件3)。光线通过介质时, 均会有光损,而本实施例由于仅设置一光学构件3,因此,可减小因设置光学构件时造成的光损,提高出光效率。本实施例中的LED照明设备仅包括一光学构件3时,LED照明设备的出光率(出光率指的是指LED照明设备射出的光通量与发光单元2产生的光通量的比值)可达到90%、92%、95%以上。本实施例中的光学构件3完全容纳于容置空间1012内,以使其不会占用LED照明设备额外的高度空间。也就是说,光学构件3在LED照明设备的高度方向上不超出底座101限定的空间。本实施例中,发光单元2与光学构件3在LED照明设备的高度方向上至少部分重叠,以降低发光单元2与光学构件3结合后的高度,并且可降低发光单元2与光学构件3之间的间距,以减小光线在该间距内的光损。进一步的,发光单元2在LED照明设备的高度方向上不超出光学构件3所限定的范围。一些实施例中,光学构件3可仅仅配置一组,光学构件3对应一组或多组发光单元2。
本实施例中的光学构件3覆盖底座101的正面的面积占底座101正面总的面积不超过50%,以节省光学构件3的材料成本,且LED照明设备重量将会降低。本实施例中的底座101的正面的面积指的是垂直于灯板201的方向上的投影面积。具体的,底座101的正面的面积为底座101的长度乘以宽度。而光学构件3覆盖底座101的正面的面积为光学构件3投影至底座101所占用的面积,实际上,该面积为光学构件的长度乘以宽度。本实施例中,光学构件3覆盖底座101的正面的面积占底座101正面总的面积超过40%,以防止光线从面积较小的光学构件3射出,而造成局部的强光。
本实施例中的光学构件3可配置为具有光扩散功能,以使出光更加均匀。例如,光学构件3为板状结构,其本身材料具有光透过及光扩散功能,以使光学构件3具有光扩散功能。又例如,光学构件3为板状结构,其具有光透过功能,并在光学构件3的外侧表面或内侧表面设置扩散层,以使光学构件3具有光扩散功能。
如图8A至图8F所示,为增加LED照明设备的结构强度,还可设置加强结构9。本实施例中的底座101的外缘处折弯形成多组侧壁(本实施例中侧壁为4组)。加强结构9包括第一加强件91,第一加强件91至少连接两组侧壁,以增加底座101结构强度。进一步的,第一加强件91连接底座101外缘的所有侧壁。例如,第一加强件91采用环状的框架,其设置于侧壁的相对的内侧,以此,可增加底座101的整体的结构强度,同时提升抗扭动的性能。一实施例中,第一加强件91的壁厚大于侧壁的壁厚。一实施例中,第一加强件91为一体式结构构成。
加强结构9还可包括第二加强件92,第二加强件92至少部分贴覆于底座101的背面。第二加强件92同时连接第一壁1014及第二壁1015。第二加强件92的两端可附接至第一加强件91。第二加强件92为条形的板状结构,其表面可设置加强筋。
加强结构9还可包括第三加强件93,第三加强件93形成于安装表面111处。具体的,安装表面111具有第一表面1111及第二表面1112,其中,灯板201贴设于第一表面1111,并且灯板201与第二表面1112保持间距。另一角度讲,第一表面1111凸设于所述第二表面1112,该结构形成了所述的第三加强件93。第三加强件93增强了安装表面111处的抗扭动性能, 确保发光体202大致配置于同一平面,并朝LED照明设备(LED照明设备正常安装状态时)竖直向下的方向出光。
如图9A至图9D所示,本发明于第九实施例中提供一种LED照明设备,本实施例中的LED照明设备的基本结构可同前述实施例。本实施例中的LED照明设备包括底座101、发光单元2、光学构件3及电源4。另外,本实施例还包括一光源承载部1,所述光源承载部1固定于所述底座101上。具体的,于一些实施例中,光源承载部1可通过紧固件固定至所述底座101,如,采用螺钉、铆钉等。于其他实施例中,光源承载部1可直接焊接、粘接或扣接至所述底座101,以使光源承载部1以可拆卸或不可拆卸的方式固定至底座101。光源承载部1具有连接壁13,连接壁13贴合于底座101的表面,以增加两者的接触面积。当LED照明设备处于工作状态(点亮)时,以使光源承载部1上的热可快速传导至底座101。光源承载部1通过连接壁13而与底座101连接。
本实施例中的发光单元2固定于所述光源承载部1上,光学构件3与发光单元2对应配置,以使发光单元2工作时产生的光线的至少一部分或全部经过光学构件3,从而重定向所述光线。
一实施例中,经光学构件3而射出的光通量的至少70%通过一次或多次反射后,从灯具射出。一实施例中,经光学构件3而射出的光通量的至少80%通过一次或多次反射后,从灯具射出。一实施例中,经光学构件3而射出的光通量的至少90%通过一次或多次反射后,从灯具射出。以此减小经光学构件3而直接的出光,避免局部的强光和减小眩光。
一实施例中,经光学构件3而射出的光通量的至少30%直接通过底座101上的反射表面1011的反射而从LED照明设备射出。一实施例中,经光学构件3而射出的光通量的至少40%直接通过底座101上的反射表面1011的反射而从LED照明设备射出。仅通过一次反射而从灯具出光,可控制反射时的光损,提高出光效率。
本实施例中,光源承载部1具有第一安装位置,所述发光单元2包括灯板201及发光体202,发光体202固定于灯板201上,发光体202可以为LED灯珠。本实施例中,灯板201贴设于第一安装位置处的光源承载部1的表面,以固定发光单元2的位置,如灯板201采用胶而粘接于第一安装位置处的光源承载部1的表面,或者第一安装位置处的光源承载部1的表面设置安装结构,以将灯板201以卡接、扣接、螺纹连接、磁吸等方式贴合于第一安装位置处的光源承载部1的表面。本实施例中,灯板201固定于第一安装位置处的光源承载部1的表面后,发光单元2与光源承载部1形成导热路径。以此,发光单元2点亮时产生的热量可传导至光源承载部1,并借由第一承载部1进行散热(一部分热直接在第一承载部1散去,另一部分热则热传导至底座101进行散热)。本实施例中的光源承载部1可采用金属材质,如铝,以提升散热效率。
本实施例中,光源承载部1具有第二安装位置,所述光学构件3设置于第二安装位置处,以固定光学构件3的位置。一实施例中,光学构件3可采用胶而粘接于第二安装位置处的光源承载部1的表面。一些实施例中,第二安装位置处设置安装结构,以将光学构件3以卡接、 扣接、螺纹连接、磁吸等方式贴合于第二安装位置处的光源承载部1的表面。
一实施例中,光学构件3包括一透镜(菲涅尔透镜),以重定向发光单元2工作时产生的光线,从而将更多的光线直接投射至底座101的反射表面。
光源承载部1上设置有挡光部11,经光学构件3后射出的光学的至少一部分射至挡光部11,并通过挡光部11的反射而投射至底座101的反射表面。通过设置挡光部11,可减小经光学构件3后而直射出的光通量,以降低眩光及避免局部强光。在LED灯具的高度方向上,发光单元2和/或光学构件3投影至遮光部11所在平面时,完全落入遮光部11所在平面的范围内。以此,避免发光单元2和/或光学构件外露,提升美观度。
一实施例中,发光单元2工作时,射至挡光部11的光通量不超过经光学构件3的光通量的40%,以控制二次反射造成的光损。本实施例中,经光学构件3射出的光通量经一次反射后从LED灯具射出的光通量大于经二次反射后从LED灯具射出的光通量。通过控制二次反射的光通量,可降低反射时造成的光损,提高出光效率。
发光单元2及光学构件3均设置有两组,且对称或大致对称的设置于光源承载部1上。光源承载部1为一体式结构构成,并具有一容置空间12,所述电源4设置于所述容置空间12内。电源4在LED照明设备的高度方向上不超过底座101所限定的范围,以使电源4不占用灯具额外的高度。同样的,光源承载部1在LED照明设备的高度方向上也可不超过底座101所限定的范围,以使光源承载部1不占用灯具额外的高度。
光源承载部1沿LED照明设备的长度方向延伸设置,且呈条状。光源承载部1在LED照明设备的宽度方向上的尺寸与LED照明设备的宽度尺寸(即底座101的宽度尺寸)的比值不超过0.2。由于光源承载部1为不发光的区域,因此,减小光源承载部1的宽度,可相应增加LED照明设备出光区域的面积。
底座101的反射表面1011(不包括被光源承载部1遮挡的部分)上至少50%、60%、70%、80%或90%的区域的表面照度达到6500lux,以增加LED照明设备的出光面积。相同的出光的光通量通过更大的出光面积射出,可使得出光更加均匀。
在LED照明设备的宽度方向上,在底座101的反射表面1011上依次截取若干50mm宽的发光区域,相邻的发光区域毗邻。任意一发光区域表面射出的光通量与相邻的发光区域表面射出的光通量的比值为0.6~1.5之间。以使LED照明设备在其宽度方向上,其出光强度过渡更加均匀,以防止底座101上形成鲜明的照度对比。
电源4包括一接线板401,电源4的电子元件设于底座101的正面(具有发光单元2的一面),而接线板401则位于底座101的背面,以便于外部电力通过接线板401而接入。接线板401设置为不超出底座101限定的高度范围,以使接线板401不占用额外的高度空间。具体的,底座101的背面具有一凹部1012,接线板401在底座101的高度方向上的至少部分或全部容置于所述凹部1012内。
如图10A至图10C,及图11A至图11C所示,本发明于一第十实施例中,提供一种LED照明设备,该LED照明设备包括:灯具及发光单元2。其中,灯具包括光源载体1。发光单 元2固定于光源载体1上。发光单元2以可拆卸的方式固定于光源载体1上,以此,发光单元2可进行更换,因此可称之为两件式LED照明设备。在包装、运输、售卖时,均可将灯具与发光单元2分开进行。发光单元2可以为T5直管灯或T8直管灯。
本发明的光源载体1包括基座11,所述基座11沿一第一方向X延伸设置,且基座11限定一容置空间,以用于容纳发光单元2,并且,发光单元2设置于容置空间后,发光单元2在基座11的高度方向上不超出容置空间所限定的范围。基座11具有底部111及设置于底部两侧的侧部112,底部111与侧部112构成基座11的容置空间。
本发明的底部111和侧部112在基座11的内侧(靠近容置空间的一侧)形成基座11的内轮廓113或部分的内轮廓,底部111和侧部112在基座11的外侧形成基座11的外轮廓114或部分的外轮廓114,其中,该内轮廓113与外轮廓114匹配。换句话说,两组基座11可叠置,且在基座11的高度方向上,两组基座11至少部分重叠。举例来讲,基座11的高度为H,两组基座11叠加后的高度小于2H。进一步的,两组基座11叠加后的高度小于1.6H。更进一步的,两组基座11叠加后的高度小于1.5、1.4、1.3、1.2或1.1H。以此,为两组LED照明设备提供了基础条件。
本发明的光源载体进一步包括端盖12,端盖12设置有两组,且分别设置于基座11在第一方向X上的两端。发光组件2可拆卸的固定于端盖12上。发光组件2包括灯管21、灯板22、发光体23、灯头24及设于灯头24上的导电针25,发光体23可以为LED灯珠,且发光体23固定于灯板22上。灯板22固定于灯管21内周面。灯头24固定于灯管21的两端。发光组件2通过其导电针25而固定至端盖12上。
参见图10A至图10N,一实施例中,端盖12包括第一构件121,第一构件121固定于基座11上,并可限制基座11在一第二方向Y上的扭曲变形。本实施例中的第一构件121包括安装部1211(如灯座)。本实施例中的第一构件121可通过卡接、扣接、插接或通过螺栓的方式等固定于基座11上。
一实施例中的第一构件121内限定一容置腔1212,电源4(图未示)可设置于该容置腔1212内。本实施例中的第一构件121在灯具(或LED照明设备)的高度方向上均不超过基座11所限定的范围。一些实施例中,如果第一构件121在在灯具(或LED照明设备)的高度方向超过基座11限定的范围的3mm以内,则也可算成第一构件121在灯具(或LED照明设备)的高度方向上均不超过基座11所限定的范围。通过将电源4设置于第一构件121内,使得电源4不会额外占用灯具(或LED照明设备)的高度空间,利于控制灯具(或LED照明设备)的高度。
参见图11A至图11C,于另一实施例中,第一构件121也可不具有上述的容置腔1212,而第一构件121仅起到安装固定发光单元2及强化基座11结构的作用。本实施例中,基座11的底部111设置一罩体116,该罩体116与底部111之间形成容置腔,以用于放置电源。本实施例中的罩体116位于基座11的容置空间内,而不会占用基座11整体的高度空间。本实施例中的罩体116内可完成走线,因此也可不设置穿线部。另外,罩体116的侧壁可配置 为具有反射功能。
参见图10C至图10G,一实施例中,基座11上设置穿线部115,穿线部115沿所述第一方向X延伸设置,且具有一穿线孔1151或穿线槽,穿线孔1151或穿线槽的两端分别与两侧的第一构件121的容置腔1212对应。穿线孔1151或穿线槽用于走线(如导线或FPC板),以用于连接两组第一构件121的容置腔1212内的电结构(如电源、接线端子、从灯座引出的导线等)。通过穿线部115,可实现隐藏式走线,确保美观度。穿线部115可直接在基座11的底部111折弯形成,并形成穿线槽,也可通过单独的穿线部115固定于基座11的底部111而形成。如果穿线部115为独立的部件,则其可通过粘接、卡接、插接、扣接、或通过螺栓连接等方式而固定于基座11上。其他实施例中,穿线单元5也可设置于基座11相对于发光单元2的另一侧。其他实施例中,当导线沿基座11背面走线(沿基座11相对于发光单元2的另一侧走线)时,也可省略上述的穿线单元。但导线沿基座11背面走线时,会额外增加LED照明设备的整体的高度。
参见图10C和图10J,第一构件121具有一抵接面1213,两组灯具(或LED照明设备)叠置时,其中一组灯具(或LED照明)的基座11的底部111背面抵接于另一组灯具(或LED照明设备)的抵接面1213。本实施例中的抵接面1213在发光单元2的高度方向上超出发光单元2,因此,发光单元2安装于灯具时,再将灯具叠加时,抵接面1213可起到保护发光单元2的作用,防止另一组灯具压迫发光单元2。本实施例中,LED照明设备的高度为W,两组LED照明设备叠加后的高度小于2W,进一步的,两组LED照明设备叠加后的高度小于1.8、1.7、1.6或1.5W。更进一步的,由于第一构件121需要配置安装部1211,则需要保证第一构件121的高度,因此,两组LED照明设备叠加后的高度大于1.3W,且小于1.6w。
参见图10C,一实施例中,端盖12进一步包括第二构件122,第二构件122可拆卸的固定于第一构件121或基座11上(灯具或LED照明设备叠置时,需先拆下第二构件122)。具体的,第二构件122可拆卸的固定于第一构件121上。第二构件122可采用卡接、扣接等方式可拆卸的固定于第一构件121上。第二构件122配置为用于与龙骨连接,即用于完成对LED照明设备的安装。
参见图10A至图10C,一实施例中,第一构件121上具有槽部1214,发光单元2的端部位于所述槽部1214内。当发光单元2采用标准长度时,通过在第一构件121上设置槽部1214,可降低端部12在第一方向X上所占用LED照明设备的空间。相应的,第二构件122上具有与槽部1214对应的开槽。
参见图11A至图11C,于另一实施例中,由于第一构件121不具有上述的容置腔1212,而第一构件121仅起到安装固定发光单元2及强化基座11结构的作用。第一构件121本身在第一方向X上的尺寸较小,因此,可不设置上述的槽部1214。对应的,第二构件122上则无需设置开槽。
参见图10A及图11A,本发明的LED照明设备可进一步包括光学单元3,光学单元3可配置反射、折射和/或散射的程度,以提供反射、折射和/或散射的任意合适的组合。另外光学 单元3还可配置为用于增加输出的光通量。
参见图10A至图10C,一实施例中,光学单元3包括一面板31,面板31设置于基座11上且面板31在基座11的高度方向上不超过超出第一构件121所限定的范围。进一步的,面板31在基座11的高度方向上不超过超出第一构件121的抵接面1213。面板31安装于灯具时,再将灯具叠加时,抵接面1213可起到保护面板31的作用,防止另一组灯具压迫面板31。
面板31并具有一打开状态及一闭合状态,在所述打开状态时,所述发光单元2露于外部,此时,便可拆装发光单元2,在所述闭合状态时,面板罩设于发光单元2,并提供对发光单元2发出的光的光学处理。本实施例中的面板31配置为具有光扩散的作用,使得出光更加均匀,以提升出发效果,降低眩光。
参见图10A至图10F,面板31通过连接单元5而设置与基座11上。具体的,连接单元5包括铰链51及固定单元52,面板31通过铰链51而可相对基座11转动的连接至基座11。所述固定单元52具有弹性臂521及扣合部522,弹性臂521以其弹性变形而实现扣合部522的位置变动,以使面板实现固定或松脱。
扣合部522上具有一支撑部5221,在闭合状态时,面板3的一侧边缘支撑于支撑部5221上。本实施例中的固定单元52进一步包括一作动部523,在闭合状态时,作动部523位于面板31的外侧,并可控制固定单元52来松脱面板31。本实施例中的固定单元52为一弹性片一体式构成。
作动部53具有一过渡部5231,面板31从打开状态切换至闭合状态时,施力面板31,面板31抵至过渡部5231,进一步施力时,面板31迫使固定单元52弹性变形,并最终通过扣合部522而到达闭合位置。此过程中无效操作作动部523,以使操作更加简单。
参见图10A至图10C,及图11A至图11C,本发明的光学单元3还可进一步包括反射部32,反射部32配置于发光单元2在LED照明设备的第二方向Y上的一侧或两侧。反射部32包括第一反射部321。一实施例中,基座11的侧部112内表面形成所述第一反射部321。反射部32可进一步包括第二反射部322。一实施例中,基座11的底部111上形成所述第二反射部322。具体的,基座11的底部折弯以形成一折弯部1111,第二反射部322形成于折弯部1111上。折弯部1111的一侧形成一容置槽1112,电源4、接线端子或导线等部件可设置该容置槽1112内,以使得这些部件不会额外占用LED照明设备的高度空间。其他实施例中,还可在穿线部115上形成所述第二反射部322。参见图11A至图11C,另一实施例中,第二反射部322形成于罩体116上。
参见图11A至图11C,于另一实施例中,光学单元3可包括光学构件33,光学构件33设于发光单元2上,并起到遮光的作用,以降低LED照明设备的眩光值。

光学构件33为柔性材质,以使得螺旋状的片状体可拉伸或折叠。因此,光学构件33在 不使用时可进行折叠,以减小存储时占用的空间。在进行发光单元2的安装时,再将光学构件33套于发光单元2上,当发光单元2安装至灯具,再将光学构件33的两端分别固定至两侧的端盖12。

本实施例中,端部12的第一加强构件122与主体部1之间形成一容置空间101,以用于安装接线单元3。

本实施例中,发光体222配置有第一发光体2221及第二发光体2222,其中,第一发光体2221及第二发光体2222可配置为可发出不同波长的光,以为LED灯具的调光调色提供基础。例如,第一发光体2221点亮时将发出具有从435nm至470nm的主波长的光,而第二发光体2222点亮时将发出具有从590nm至640nm的主波长的光。
本实施例中,光学构件23罩设于发光单元22上,且光学构件23固定于支撑单元21上。本实施例中的光学构件23大体上来讲,仅覆盖基板221,而不会额外的覆盖支承单元1的面积。举例来讲,光学构件23覆盖支承单元1的正面的面积占支承单元1正面总的面积不超过20%。本实施例中的支承单元1的正面的面积指的是垂直于基板221的方向上的投影面积。具体的,支承单元1的正面的面积为支承单元1的长度乘以宽度。而光学构件23覆盖支承单元1的正面的面积为光学构件23投影至支承单元1所占用的面积,实际上,该面积为光学构件23的长度乘以宽度。本实施例中,光学构件23为提供对基板221的覆盖,且不至于覆盖过多的支承单元1的正面的面积,设置光学构件23的宽度与基板221的宽度的比值为1~2 之间。进一步的,设置光学构件23的宽度与基板221的宽度的比值为1~1.3之间。
本实施例中,光学构件23包括第一配光单元231及第二配光单元232。本实施例中的第一配光单元231配置为条状,且沿第一配光单元231的长度方向设置一容置槽2311,发光单元22在高度方向上的至少一部分位于容置槽2311内。第二配光单元232设置于第一配光单元231的表面,且第二配光单元232与容置槽2311在光学构件23的高度方向上分别位于第一配光单元231的相对的两侧。发光单元22的发光体222与第二配光单元232对应配置。具体的,发光体222(第一发光体2221和第二发光体2222)与第二配光单元3002一一对应配置。
进一步的,发光单元22的发光体222完全容纳于容置槽2311内。本实施例中的发光体22表面至容置槽2311的底面(容置槽2311对应于发光体222的表面)的距离为A(A大于等于0),发光体222表面至第二配光单元3002的距离为B,A与B的关系满足以下条件:A:B的值大于0.05且小于0.25。进一步的,A与B的关系满足以下条件:A:B的值大于0.1且小于0.2。当A和B满足以上关系时,可控制发光222发出的光可大部分或完全对应于第二配光单元232。也就是说,不考虑发光体222产生的光在界面处的反射的话,发光体222产生光将完全投射至第二配光单元232,并由第二配光单元232做光学处理。
本实施例中的支撑座211上具有卡槽2111,光学构件23和发光单元22的基板221同时卡入卡槽2111内,以完成固定。
本实施例中的发光体222产生的光通量的至少70%经由第二配光单元232而从LED灯具直接射出。其余的光通量则由第一配光单元231射出。进一步的,发光体222产生的光通量的至少80%经由第二配光单元232而从LED灯具直接射出。更进一步的,发光体222产生的光通量的至少90%经由第二配光单元232而从LED灯具直接射出。
本实施例中的容置槽2311的底面形成入光部23111,发光体222产生的光线的至少一部分(例如发光体222产生的光通量的至少80%,或者发光体222产生的光通量的至少90%)透过入光部23111而进入光学构件23,并进入第二配光单元232。在一实施例中,在不考虑入光部23111处的反射的情况下,发光体222产生的光通量全部直接进入入光部23111,也就是说,发光体222的出光范围完全对应于入光部23111内,以提高出光效果(出光效率及出光光型)。本实施例中的第二配光部232包括第一出光部2321及第二出光部2322。第一出光部231及第二出光部232的表面的照度比值大于0.3、0.4、0.5、0.6、0.7、0.8或0.9,且小于2、1.9、1.8、1.7、1.6或1.5,以使在LED灯具的出光范围内的出光更加均匀。本实施例中,第一出光部2321包括一平面或大致的平面,第二出光部2322包括一锥面或大致的锥面,第二出光部2322围绕第一出光部2321而设置。
本实施例中的第二出光部2322具有一轮廓线,该轮廓线沿第二配光部232的中轴线回转360度而形成第二出光部2322的外轮廓。本实施例中的第二出光部2322的锥面的外轮廓的轮廓线的斜率的绝对值为0.3~0.6之间。进一步的,第二出光部2322的锥面的外轮廓的斜率的绝对值为0.4~0.5之间。第二出光部2322起到调整光型的作用,当第二出光部2322的锥面 的外轮廓的轮廓线的斜率的绝对值在上述区间时,可获得较佳的出光效果(出光角度及出光光型)。本实施例中,计算第二出光部2322的锥面的外轮廓的轮廓线的斜率时,以图12L的放置方式来计算,即光学构件23位于发光单元22的上方。
本实施例中LED灯具,从出光路径上来讲,发光体222工作时产生的光通量的至少80%、85%或90%,经第二配光单元232而直接从LED灯具射出(该部分光经第二配光单元232后,不经支承单元1的反射,以降低反射时可能的光损),从而可提高出光效率。本实施例中,发光体222产生的光线的一部分(小于总光通量的20%、15%、或10%)透过第一配光单元231而射至支承单元1上,并通过支承单元1的反射而直接从LED灯具射出,无需通过现有技术中的透光板或扩散板等进行出光。总体上讲,本实施例中的LED灯具所射出的光中,经支承单元1反射而射出的光小于经第二配光单元232而射出的光,通过减少依靠反射的出光,可降低光损,提高出光效率。本实施例中,可将通过支承单元1反射的出光控制在总的出光的光通量的10%以下,而90%以上的出光则不通过反射而直接出光,以降低反射时造成的光损。
其他实施例中,第二配光单元232可采用球面结构或多边形棱镜结构。
如图12M所示,本实施例中,为控制LED灯具的出光均匀性,发光单元22点亮时从LED灯具射出的光线,在一第一区域A范围内的照度与在一第二区域B范围内的平均照度的比值大于0.3、0.4、0.5、0.6、0.7、0.8或0.9,而小于2。优选的,在一第一区域A范围内的照度与在一第二区域B范围内的平均照度的比值大于0.5,而小于1.5。其中,第一区域A与第二区域B位于同一平面上。且第一区域A及第二区域B均位于一第三区域C(第三区域C与第一区域A及第二区域B位于同一平面)内,而第三区域C对应的光束角c为90度、80度、60度或50度。本实施例中的光束角c可小于LED灯具的发光角度。本实施例中,以光束角50度范围内的照度差异来考量出光均匀性,以此,第三区域C对应的光束角为50度。另外,第一区域A及第二区域B可以为第三区域C内的任意区域。需要注意的是,本处所指的光束角a并非指的有光范围的边界线所形成的夹角。本实施例中的第三区域C的中心或圆心的位置与LED灯具对应,即LED灯具沿光轴D投影至第三区域C时,其位置落于或大致落于第三区域C的中心或圆心。本实施例中,第一区域A与第二区域B所在的平面与光轴D垂直或大致垂直。
如图12N所示,本实施例中,为控制LED灯具的出光均匀性,发光单元22点亮时从LED灯具射出的光线,在一第一区域A范围内的照度与在一第二区域B范围内的平均照度的比值大于0.3、0.4、0.5、0.6、0.7、0.8或0.9,而小于2。优选的,在一第一区域A范围内的照度与在一第二区域B范围内的平均照度的比值大于0.5,而小于1.5。其中,第一区域A与第二区域B位于同一平面上,且同心或大致同心设置(假设各区域为圆形或大致的圆形,其中心或圆心位于相同位置)。且第一区域A及第二区域B均位于一第三区域C(第三区域C与第一区域A及第二区域B位于同一平面)内,而第三区域C对应的光束角c为90度、80度、60度或50度。本实施例中的光束角可小于LED灯具的发光角度。本实施例中,以光束角50度范围内的照度差异来考量出光均匀性,以此,第三区域C对应的光束角c为50度。另外, 第一区域A及第二区域B与第三区域C同心或大致同心设置,且第一区域A对应的光束角a和第二区域B对应的光束角b均小于第三区域C对应的光束角c。需要注意的是,本处所指的光束角并非指的有关范围的边界线所形成的夹角。本实施例中的第三区域C的中心或圆心的位置与LED灯具对应,即LED灯具沿光轴D投影至第三区域C时,其位置落于或大致落于第三区域C的中心或圆心。本实施例中,第一区域A与第二区域B所在的平面与光轴D垂直或大致垂直。
本实施例中,LED灯具的厚度不超过30mm,也就是说,在整灯厚度不到30mm的前提下,LED灯具通过光学构件23的设计,可达到前述的出光均匀性。进一步的,LED灯具的厚度可控制到不超过26mm,并满足前述的光学效果,如出光均匀性。
