具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚,下面将结合本公开实施例的附图,对本公开实施例的技术方案进行清楚、完整地描述。显然,所描述的实施例是本公开的一部分实施例,而不是全部的实施例。基于所描述的本公开的实施例,本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例,都属于本公开保护的范围。
除非另外定义,本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性,而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同,而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接,而是可以包括电性的连接,不管是直接的还是间接的。
照明模块包括底座、发光元件、透镜组件和散热器;底座和散热器集成为一体并与透镜组件构成容置空间,发光元件设置在容置空间内。通常,照明模 块的底座的边缘和透镜组件的边缘均设置有凹槽,通过在凹槽中设置密封圈,然后通过透镜压框或卡扣对透镜施加朝向底座的压力以压紧胶槽中的密封圈,从而将上述的容置空间密封,且密封圈受到正向的挤压力。另外,还可在底座和透镜组件的边缘施加密封胶,从而增强密封效果。通过将上述的容置空间密封可防止外界水氧腐蚀发光元件,从而可提高照明模块的使用寿命。
然而,透镜压框或卡扣会占据透镜组件的一部分面积,导致透镜组件的发光面所占面积比例减小,并同时减小了容置空间的面积,从而降低了单位面积内发光元件的数量和透光组件的透光面积,进而降低了发光效率。
对此,本公开实施例提供一种照明模块及其组装方法和照明装置。该照明模块包括底座、透光组件和密封圈;底座包括底板和设置在底板上的底座侧壁;透光组件,与底座在垂直于底板的方向上相对设置,以在透光组件和底板之间形成容置空间,透光组件包括透光组件侧壁,透光组件侧壁与底座侧壁在平行于底板的方向上相对间隔设置;密封圈,至少部分设置在透光组件侧壁和底座侧壁之间,并与透光组件侧壁与底座侧壁分别紧密接触,以将容置空间密封。由此,该照明模块可通过底座侧壁、透光组件侧壁和密封圈实现将容置空间密封,无需在透光组件的边缘上设置压框、卡扣或螺钉。在照明模块的外围尺寸相同的情况下(此处的外围尺寸不包含照明模块与外部连接的结构),该照明模块可增加容置空间的面积以设置更多的发光元件,从而可提高照明模块的发光面的利用率,并在照明模块的功率相同的情况下,提高照明亮度和发光效率。另外,由于无需在透光组件的边缘上设置压框、卡扣或螺钉,该照明模块还可降低产品的不良率、节省安装步骤、提升安装效率、并降低成本。
下面,结合附图对本公开实施例提供的照明模块及其组装方法和照明装置进行详细的说明。
图1A为根据本公开一实施例提供的一种照明模块的结构示意图;图1B为根据本公开一实施例提供的一种照明模块的平面示意图;图2A为本公开一实施例提供的照明模块在图1A所示的AA区域的局部放大示意图。
如图1A、1B和图2A所示,该照明模块包括底座110、透光组件120和密封组件130,例如密封组件130可为密封圈底座110包括底板112和设置在底板112上的底座侧壁114,底座侧壁114与底板112围成容纳槽210;透光组件120至少部分设置在容纳槽210内以在透光组件120和底板110之间形成容置空间220,透光组件120包括透光组件侧壁124,透光组件侧壁124与底 座侧壁114相对间隔设置;透光组件120与底座110在垂直于底板112的方向上相对设置,透光组件侧壁124与底座侧壁114在平行于底板112的方向上相对间隔设置。密封圈130至少部分设置在透光组件侧壁124和底座侧壁114之间,并与透光组件侧壁124和底座侧壁114分别紧密接触,以将容置空间220密封。需要说明的是,上述的底座侧壁和透光组件侧壁均为具有一定厚度的结构,而并非仅仅为二维的表面;同样地,下文中的各种侧壁也为具有一定厚度的结构,而并非仅仅为二维的表面。
在本公开实施例提供的照明模块中,容置空间内可设置发光元件,发光元件用于发光,而将容置空间密封可防止外界水氧腐蚀发光元件,从而可提高该照明模块的使用寿命。由于密封圈设置在透光组件侧壁和底座侧壁之间,并与透光组件侧壁和底座侧壁分别紧密接触,因此该照明模块可通过密封圈、透光组件侧壁和底座侧壁来实现将容置空间密封,即提供一种侧面密封的方式。此时,密封圈受到垂直于底座侧壁的力而处于压缩状态,不需要在透光组件的边缘上设置压框、卡扣或螺钉等额外的固定结构。在照明模块的外围尺寸相同的情况下,该照明模块可增加容置空间的面积以设置更多的发光元件(例如发光二极管灯珠),从而可提高照明模块的发光面的利用率,并在照明模块的功率相同的情况下,提高照明亮度和发光效率。另外,由于无需在透光组件的边缘上设置压框、卡扣或螺钉等额外的固定结构,该照明模块还可降低产品的不良率、节省安装步骤、提升安装效率、并降低成本。值得注意的是,相对于密封圈受到垂直于底板的力而处于压缩状态的情况,当密封圈受到垂直于底座侧壁的力而处于压缩状态时,密封圈在垂直于底座侧壁的方向上的尺寸较小,从而可进一步提高照明模块的发光面的利用率,并在照明模块的功率相同的情况下,提高照明亮度和发光效率。
以具体的实施例进行对比分析,图2B为一种照明模块的尺寸图;图2C为本公开一实施例提供的一种照明模块的尺寸图。图2B所示的照明模块的密封圈是设置在底座的底板和透光组件之间,且占用了透光组件的边缘区域的部分面积,并且密封圈所占的面积较大;而本公开实施例提供的照明模块将密封圈设置在底座侧壁和透光组件侧壁之间,使得图2B所示的照明模块中的透光组件的边缘区域中原先被密封圈占用的面积可用于设置发光元件,大大提高了照明模块的发光面的利用率。此外,图2B所示的照明模块在透光组件上设有两个螺钉槽也会占用一部分面积,螺钉槽是为了螺钉固定电路板时预留空间; 本公开实施例提供的照明模块可不使用螺钉固定电路板,透光组件上无需设置螺钉槽,进一步提高了照明模块的发光面的利用率。
例如,如图2B所示的照明模块的外围尺寸(含卡扣式压框)的长宽为:241.4mm*75.4mm,该照明模块上可排布发光元件的面积为216.6mm*50.4mm=10917mm 2,两个螺钉槽占用面积90mm 2*2=180mm 2,走线槽占用面积460mm 2,即可排布发光元件的有效面积为10277mm 2,可排布28颗发光元件。如图2C所示,本公开一实施例提供的照明模块的外围尺寸(含底座侧壁)的长宽为:236mm*74mm,该照明模块上可排布发光元件的面积为222.9mm*60.9mm=13575mm 2,走线槽占用面积460mm 2,即可排布发光元件的有效面积为13115mm 2,可排布36颗发光元件。本公开实施例提供的照明模块上可排布发光元件的有效面积比图2B所示的照明模块的有效面积提升了约28%;本实施例提供的照明模块的外围尺寸略小于图2B提供的照明模块的外围尺寸,但是其可以多排布约8颗发光元件,那么在照明模块外围尺寸相同的条件下,本公开实施例理论上可以排布比8颗更多的发光元件,进一步提高照明模块的发光面的利用率。
在照明模块的功率、透光组件的透过效率、发光元件的光电参数相同的条件下,以照明模块功率为40W,发光元件为Lumileds的LUXEON 5050为例,当发光元件为28颗时,驱动电流约60mA;当发光元件为36颗时,驱动电流约47mA;图2D为单颗发光元件的电流与归一化光通量输出的关系曲线,图2E为单颗发光元件的电压与电流的关系曲线(图2D和图2E均来自Lumileds的LUXEON 5050的产品规格书)。当发光元件的测试电流为160mA时,此时单颗发光元件输出的光通量为650lm,在图2D中把650lm归一化,作为数值1,根据发光效率计算公式:发光效率=光通量/功率,下面进行对比分析。
根据图2D,当驱动电流为60mA时,发光元件的归一化光通量输出约为0.4,实际光通量为650lm*0.4=260lm,根据图2E,当电流为60mA时,电压约22.3V,此时发光元件的发光效率为:260lm/(60mA*22.3V)≈194.32lm/W;
根据图2D,当驱动电流为47mA时,发光元件的归一化光通量输出约为0.34,实际光通量为650lm*0.34=221lm,根据图2E,当电流为47mA时,电压约21.9V,此时发光元件的发光效率为:221lm/(47mA*21.9V)≈214.71lm/W;
在照明模块的功率、透光组件的透过效率、发光元件的光电参数相同的条件下,本公开一实施例提供的照明模块相比图2B所示的照明模块,其发光效率可提高(214.71-194.32)/194.32≈10.5%。
图3A为一种的照明模块的受力分析示例图;图3B为本公开一实施例提供的一种照明模块的受力分析示意图;图3C为本公开一实施例提供的另一种照明模块的受力分析示意图;图3D为一种照明模块的剖面示意图;图3E为另一种照明模块的剖面示意图;图3F为本公开一实施例提供的另一种照明模块的剖面示意图。
如图3D和图3E所示,其提供的照明模块一般是利用卡扣或螺钉的拉紧力将透光组件120紧固在底座110上,密封圈设置在透光组件和底座之间,卡扣和螺钉都是非连续间隔设置在透光组件120边缘,透光组件120受到的压紧力是不均匀的,密封圈受到的正向压力也是不均匀的,且考虑到成本、工艺、卡扣的弹性形变、螺钉相互之间会干涉等因素,卡扣和螺钉不能设置得很密集;而且将卡扣式透光组件固定到底座上时,卡扣可以承受的最大压紧力取决于卡扣的强度,卡扣不能做得很厚,否则会影响其弹性形变导致透光组件无法安装;相反,卡扣也不能做的很薄,否则其强度不够导致很容易断裂,从而影响安装效果;利用螺钉将透光组件固定时,打螺钉的力不能过大,否则容易将透光组件破坏,且即便打完螺钉时透光组件没有破裂,由于螺钉拧紧后存在扭矩,透光组件有很大的内应力,导致透光组件在使用过程中也容易损坏。另外,利用卡扣或螺钉固定透光组件时,透光组件在相邻卡扣(或螺钉)之间的部分容易拱起(如图3D和3E虚线框处),在拱起处,密封圈受到的正向压力减小,存在渗水隐患。
而本公开一实施例提供的照明模块采用侧面密封方式,如图3F所示,密封圈受到透光组件侧壁和底座侧壁的侧向挤压力实现照明模块的密封,透光组件侧壁和底座侧壁均是连续的,所以密封圈受到的挤压力是均匀的、连续的;且因为力的作用是相互的,透光组件侧壁受到密封圈的张紧力也是均匀的。这样,一方面,使得透光组件容易安装到底座上,而且透光组件侧壁不会断裂,不会影响安装效果;同时,透光组件侧壁不会拱起,避免渗水隐患;另一方面,在使用过程中,透光组件也不会从底座中松脱出来,且可以通过增加透光组件侧壁厚度等设计使其比卡扣承受更大的工装压力。
下面,以卡扣式透光组件为例,进行通常的照明模块与本公开一实施例提 供的照明模块做受力分析对比。
如图3A所示,该照明模块在透光组件120的边缘设置卡扣129并与底座110卡合,密封圈130设置在透光组件120和底座110之间,通过卡扣129进行压紧固定,从而实现透光组件120和底座110的固定。此时,密封圈130受到卡扣提供129的向下的压力F(从透光组件到底座的方向上的压力)后,底座110对密封圈130也会产生一个向上的力F。
如图3B所示,该照明模块可为本公开实施例提供的一种照明模块。如图3B所示,当有拔模角度存在的情况下,假设底座侧壁114对密封圈130的力在垂直方向的分力F1=F,那么底座侧壁114对密封圈130的力在水平方向的分力F2=Fcotɑ,ɑ为拔模角度(即F1和F2的夹角),一般拔模角度都是很小的,当ɑ=1°时,F2=57.3F,此时F2能产生的最大静摩擦力为f=μF2,密封圈的摩擦系数约0.8,所以f=45.8F。而最大静摩擦力f的方向和垂直方向的分力F1的方向相反。由此可知,本公开实施例提供的照明模块在存在拔模角度的情况下,可以提供防止透光组件松脱的力为f-F1=44.8F,该照明模块无需在透光组件的边缘上设置压框、卡扣或螺钉也能确保密封圈和透光组件不松脱;并且,本公开实施例提供的照明模块提供的侧向压力F2可达57.3F,从而能确保防水性能。
如图3C所示,该照明模块可为本公开实施例提供的另一种照明模块。如图3C所示,当拔模角度不存在的情况下,即当ɑ=0时,底座侧壁114对密封圈130的力在垂直方向的分力F1=0,只有水平方向的力F2。此时,防止透光组件松脱的力为f,由于没有垂直方向的分力,从理论上讲该照明模块可以提供更大的侧向压力,更能确保密封圈和透光组件不松脱。
以上定量分析只供说明本公开实施例提供的照明模块可提供更大的压力去压紧密封圈,上述分析的过程只是为了得出一个定性的结论,实际受力情况要根据项目实际受力需求而定。根据胡克定律,实际应用中的受力取决于密封圈的压缩量,以上分析仅为了说明本公开实施例提供的照明模块的结构设计能够给密封圈提供更大的力,从而使密封圈受到更大的静摩擦力,防止透光组件松脱,且因为密封圈被压地更紧、照明模块的密封效果也会更好。
例如,如图1B所示,底座侧壁114可为围绕底板一周的围墙结构,同样地,透光组件侧壁124也可为围绕透光组件120的边缘一周的围墙结构。此时,在透光组件侧壁124和底座侧壁114之间密封圈可为对应的环形结构。
例如,如图1B所示,底座侧壁114在底板上正投影的形状可为圆角矩形环、透光组件侧壁124在底板上正投影的形状可为圆角矩形环。当然,本公开实施例包括但不限于此,底座侧壁和透光组件侧壁在底板上正投影的形状也可为其他环形结构,只要可将容置空间密封即可。
在一些示例中,如图1A、图1B和图2A所示,透光组件120可为透镜组件,即包括至少一个透镜部122。当然,本公开实施例包括但不限于此,透光组件120可也为其他透光的部件。
在一些示例中,如图1A、图1B和图2A所示,透光组件侧壁124被配置为向密封圈130施加朝向底座侧壁114的力,以使密封圈130处于压缩状态。
在一些示例中,密封圈的邵氏硬度范围在25-40之间。密封圈的邵氏硬度越大,密封圈越硬,对密封圈进行压缩所需要的力就越大,当密封圈被压缩而产生的反弹力容易将透光组件顶起,从而造成各种不良。而封圈的邵氏硬度越小,密封圈越软,则密封圈的形变量太大,反而容易导致密封效果不好。因此,本示例提供的照明模块通过将密封圈的邵氏硬度范围设置在25-40之间,可具有较好的密封效果(例如,可通过防水测试)的同时,密封圈不会产生较大的反弹力。另外,当密封圈的邵氏硬度范围在25-40之间时,还提高密封圈的寿命。
例如,密封圈的邵氏硬度范围在25-30之间,从而可更好兼顾密封效果和较长的使用寿命。
在一些示例中,密封圈在垂直于底座侧壁的方向上的压缩率的范围在15%-22%。此时,该照明模块可具有较好的密封效果(例如,可通过防水测试)的同时,密封圈不会产生较大的反弹力。需要说明的上,本公开实施例提供的照明模块在不设置密封胶仅设置密封圈时可通过防水测试,例如IP68防水等级测试。
在一些示例中,当第二间隔在垂直于底座侧壁的方向上的尺寸为W,密封圈在垂直于底座侧壁的方向上的压缩量为σ时,压缩率计算公式为:

当密封圈的邵氏硬度范围在25-40之间,第二间隔在垂直于底座侧壁的方向上的尺寸范围为2.1-2.3毫米时,通过选择不同的压缩量(σ)进行防水测试,例如,压缩量(σ)分别为1mm、0.7mm、0.6mm、0.5mm和0.4mm。 根据测试结果,当压缩量(σ)为1mm时,密封圈被压缩后产生的反弹力较大,会将透光组件的边缘顶起;当压缩量(σ)为0.7mm时,密封圈被压缩后产生的反弹力仍然较大;当压缩量(σ)为0.6mm时,密封圈被压缩后不会将透光组件的边缘顶起,并且通过防水测试;当压缩量(σ)为0.5mm时,密封圈被压缩后不会将透镜边缘顶起,并且通过防水测试;当压缩量(σ)为0.4mm时,密封圈被压缩后不会将透镜边缘顶起,并且通过防水测试;当压缩量(σ)小于0.4mm时,密封圈受到的挤压力不够,没有通过防水测试。因此,可以得出密封圈在垂直于底座侧壁的方向上的压缩量的范围为0.4-0.6毫米,并且密封圈在垂直于底座侧壁的方向上的压缩率的范围在15%-22%。
在一些示例中,如图1A、图1B和图2A所示,该照明模块还包括密封胶160,密封胶160的至少一部分位于透光组件侧壁114和底座侧壁124之间且位于密封圈130远离底板112的一侧。例如,密封圈160的至少一部分位于透光组件侧壁114和底座侧壁124之间的间隔的一个端部,该端部位于密封圈130远离底板112的一侧。密封圈130可起到进一步密封的作用,并且还可起到将透光组件和底座固定的作用。
在一些示例中,如图1A、图1B和图2A所示,透光组件侧壁124包括第一侧壁1241和第二侧壁1242;第一侧壁1241位于第二侧壁1242远离底座110的一侧,即位于图2A所示的第二侧壁1242的上方,第一侧壁1241与底座侧壁114相对间隔设置,且与底座侧壁114之间具有第一间隔301;第二侧壁1242与底座侧壁114相对间隔设置,且与底座侧壁114之间具有第二间隔302;第二间隔302大于第一间隔301,并且密封圈130至少部分设置在第二侧壁1242与底座侧壁114之间,并与第二侧壁1242与底座侧壁114分别紧密接触。由此,密封圈与第二侧壁与底座侧壁分别紧密接触,可将容置空间密封;而通过设置与底座侧壁距离较近的第一侧壁可使得第一侧壁部分位于密封圈上方,从而可在照明模组的安装和使用过程中放置密封圈跳出。
在一些示例中,如图1A、图1B和图2A所示,第一侧壁1241靠近密封圈130的一侧具有第一侧面141,第一侧面141与第二侧壁1242相连。密封圈130与第一侧面141接触。
在一些示例中,如图1A、图1B和图2A所示,第一侧壁1241靠近底座侧壁114的表面和第二侧壁1242靠近底座侧壁114的表面平行。第一侧面141可与第二侧壁1242靠近底座侧壁114的表面垂直。
在一些示例中,如图1A、图1B和图2A所示,密封圈130包括第一密封部132,第一密封部132设置在透光组件侧壁124和底座侧壁114之间,在密封圈130处于未被压缩的状态下,第一密封部132包括第一平面1322、第一弧面1323和第一斜面1324。第一平面1322用于与第二侧壁1242接触;第一弧面1323与第一平面1322相对设置,朝向外侧突出且被配置为与底座侧壁114接触;第一斜面1324与第一弧面1323相连,且位于第一弧面1323靠近底座110的一侧,第一斜面1324所在的平面与第一平面1322所在的平面形成靠近第一侧壁114的锐角。第一斜面1324被配置为与第二侧壁1242间隔设置以形成形变空间。需要说明的是,上述的第一平面指的是至少在垂直于底板的方向为平面,当密封圈在底板上的正投影的形状为圆角多边形环(例如,圆角矩形环)时,在圆角处,第一密封部与第二侧壁接触的表面可根据第二侧壁的形状进行相应地改变;例如,当圆角处的第二侧壁为曲面时,第一密封部与第二侧壁接触的表面也可为曲面。
在本示例提供的照明模块中,第一平面1322用于与第二侧壁1242接触,从而可使得密封圈130与第二侧壁1242具有较好的接触,使得密封圈130可稳定地套设在透光组件120上,避免密封圈130扭曲。第一弧面1323与第一平面1322相对设置且用于与底座侧壁114接触,第一弧面1323具有一定的导向作用,从而可使得密封圈130能更顺畅的挤压到底座侧壁114上;第一斜面1324与第一弧面1323相连。第一斜面1324所在的平面与第一平面1322所在的平面形成靠近第一侧壁1241的锐角,一方面,第一斜面1324也就有一定的导向作用,从而可便于安装,另一方面,第一斜面1324可与底板112形成一定的空间,从而在密封圈130被压缩时提供预留空间。需要说明的是,图2A中的密封圈130处于被压缩状态,第一弧面可参照图2A中的虚线所示。
在一些示例中,如图1A、图1B和图2A所示,第一弧面1323与底座侧壁114紧密接触并处于压缩状态以形成接触面,第一斜面1324位于第一侧壁1241和底板112之间,第一斜面1324在底板112上的正投影与第二间隔302在底板112上的正投影至少部分交叠。由此,在安装的时候,第一斜面1324可起到导向作用,从而可便于安装;并且,第一斜面1324与底板112会形成一定的空间,从而在密封圈130被压缩时提供预留空间。需要说明的是,上述的接触面的尺寸随着密封圈的压缩压力的增大而增大。
在一些示例中,如图1A、图1B和图2A所示,密封圈130还包括第二密 封部134,第二密封部134设置在透光组件120和底板112之间,且与第一密封部132相连。第一密封部132和第二密封部134为一体结构,通过第二密封部134,密封圈130可更好地包裹在透光组件120上,并且可在将透光组件120和密封圈130下压到底座上时可防止密封圈扭曲。
在一些示例中,如图1A、图1B和图2A所示,照明模块还包括:电路板170和设置在电路板170上的至少一个发光元件190;电路板170和发光元件190均位于容置空间220内。因此,电路板170和发光元件190可免于外界水氧的腐蚀,从而具有更长的使用寿命和稳定性。
在一些示例中,如图1A、图1B和图2A所示,当透光组件120为透镜组件时,至少一个透镜部122与至少一个发光元件190可一一对应设置。各个透镜部122可为对应的发光元件190配光,从而提高该照明模块的出光效果。
在一些示例中,如图2A所示,电路板170靠近底座侧壁114的边缘与底座侧壁114之间具有间隔,第二密封部134设置在电路板170靠近底座侧壁114的边缘与底座侧壁114之间。第二密封部134与电路板170不交叠,从而可使得透光组件120可紧贴在电路板170上。由此,一方面,透光组件可起到固定电路板的作用,另一方面也可使得电路板上的发光元件与透镜部紧密贴合,提高出光效果。在一些示例中,如图2A所示,第二密封部134在垂直于底板112的方向上的尺寸小于电路板170在垂直于底板112的方向上的尺寸(即电路板的厚度)。
在一些示例中,如图1A、图1B和图2A所示,该照明模块还包括散热器180;散热器180设置在底板112远离透光组件120的一侧,从而为容置空间内设置的发光元件进行散热。
在一些示例中,如图1A、图1B和图2A所示,散热器180和底座110可为一体结构。也就是说,散热器集成在底座远离透光组件的表面。此时,底座可采用热传导率较高的材料,例如金属制作,从而可提高该灯壳的散热效果。当然,本发明实施例包括但不限于此,底座也可采用其他合适的材料制作。
在一些示例中,如图1A、图1B和图2A所示,散热器180包括从底座110远离所透光组件120的表面向远离透光组件120的方向延伸的多个散热鳍片185,从而可具有较好的散热效果。
在一些示例中,处于自然状态下,密封圈130的内围尺寸小于透光组件120的外围尺寸,从而可牢固地套设在透光组件上。另外,密封圈的内围尺寸小于 透光组件的外围尺寸还可防止密封圈跳出。需要说明的是,当透光组件包括上述的第一侧壁和第二侧壁时,上述的透光组件的外围尺寸可为第一侧壁的外围尺寸。需要说明的是,上述的自然状态是指密封圈不受外力的状态。
图4为根据本公开一实施例提供的照明模块在图1A所示的AA区域的另一种局部放大示意图。如图4所示,透光组件侧壁124还包括第三侧壁1243;第三侧壁1243与底座侧壁114相对间隔设置,且与底座侧壁114之间具有第三间隔303,第三侧壁1243位于第二侧壁1242靠近底板112的一侧,第三间隔303小于第二间隔302,第一侧壁1241、第二侧壁1242和第三侧壁1243形成向透光组件120的中心凹入的凹入部150,密封圈130位于凹入部150。由此,密封圈130可更好地嵌设在凹入部150中,避免密封圈130在安装和使用的过程中发生扭曲、位移,从而可提高密封效果。
在一些示例中,如图4所示,第三侧壁1243靠近密封圈130的一侧具有第二侧面142,第二侧面142与第二侧壁1242相连。
在一些示例中,如图2A和图4所示,透光组件侧壁124包括第四侧壁1244,位于第一侧壁1241远离底板112的一侧,底座侧壁114包括第五侧壁1145,第四侧壁1244和第五侧壁1145相对间隔设置,并具有第四间隔304,第四间隔304大于第一间隔301。第四间隔304和第一间隔301和第二间隔302相连通。照明模块还包括密封胶160,至少位于第四间隔304以将第一间隔301和第二间隔302密封。由此,上述的第四间隔304和密封胶160可进一步将容置空间220密封。另外,由于第一间隔的尺寸较小,在第一间隔加注密封胶的难度较大,而将第四间隔设置得大于第一间隔,从而可更好地加注密封胶,从而便于操作。
在一些示例中,如图2A和图4所示,第四间隔304在垂直于底座侧壁114的方向上的尺寸远远大于第一间隔301在垂直于底座侧壁114的方向上的尺寸,例如,第四间隔304在垂直于底座侧壁114的方向上的尺寸远远大于第一间隔301在垂直于底座侧壁114的方向上的尺寸的4倍,从而可更好地加注密封胶。
在一些示例中,如图2A和图4所示,第一间隔301在底板112上的正投影落入第四间隔304在底板112上的正投影之内。也就是说,相对于第一侧壁1241靠近底座侧壁114的表面,第四侧壁1244靠近底座侧壁114的表面更靠近该照明模块的中心;相对于底座侧壁114与第一侧壁1241相对的表面,第 五侧壁1145靠近第四侧壁1244的表面更远离该照明模块的中心。
在一些示例中,如图2A和图4所示,密封胶160可位于第一间隔301和第二间隔302中并与密封圈130接触。当然,本公开实施例包括但不限于此,密封胶也可仅位于第四间隔中。
需要说明的是,当透光组件侧壁包括第三侧壁时,密封圈的横截面形状可为圆形、马蹄形等其他形状,只要可起到密封效果即可。
在一些示例中,如图2A和图4所示,底板112包括凹槽1125,凹槽1125位于底板112靠近底座侧壁114的位置,密封圈130在底板112上的正投影与凹槽1125至少部分重叠。由此,如图2A所示,凹槽1125可为密封圈的膨胀提供预留空间,或者,如图4所示,凹槽1125可为第三侧壁1243提供预留空间。
图5A和图5B为本公开一实施例提供的另一种照明模块在图1A所示的AA区域的局部放大示意图。如图5A和图5B所示,底座侧壁114包括凹陷部1147,凹陷部117从底座侧壁114靠近透光组件侧壁124的表面凹入。凹陷部117可用于容纳密封圈130,从而进一步防止密封圈130脱出。例如,凹陷部1147与第二侧壁1242可相对设置。
例如,如图5A所示,凹陷部1147可为方形凹陷部;如图5B所示,凹陷部1147为弧形凹陷部。例如,凹陷部1147可位于第五侧壁1145靠近底板112的一侧。
图6为根据本公开一实施例提供的照明模块在图1A所示的BB区域的一种局部放大示意图。如图1A和图6所示,透光组件120包括位于透光组件120的中心的第一卡扣125,底座110包括位于底座110的中心的第二卡扣115,第一卡扣125和第二卡扣115相互配合以彼此连接,从而可将透光组件120和底座110固定。由此,该照明模块可通过卡扣结构进行固定;另外,通过将卡扣结构设置在透光组件的中心和底座的中心,可较好地防止透光组件的中心拱起。当然,本公开实施例提供的照明模块也可不设置卡扣结构,从而降低透光组件和底座的制作难度和降低安装难度。
例如,第一卡扣125的数量可为两个,第二卡扣115的数量也可为两个。当然,本公开实施例包括但不限于此,第一卡扣125的数量也可为其他数量,第二卡扣115的数量也可为其他数量。
例如,第一卡扣125和第二卡扣115均为倒钩结构,在组装时,第一卡扣 125和第二卡扣115的倒钩结构上设有斜面,从而可起到导向作用,更容易扣合。
图7为根据本公开一实施例提供的照明模块在图1A所示的CC区域的一种局部放大示意图。如图7所示,发光元件190可设置在电路板170上,电路板170和其上的发光元件190均设置在容置空间中。
需要说明的是,在本公开实施例提供的照明模块中,电路板和底座可为相互独立部件;当然,电路板也可与底座集成为一体,即底板上设置有电路结构,发光元件直接设置在底板上。
在一些示例中,如图7所示,底座110包括定位销117,电路板170包括定位孔177,定位孔177被配置为容纳定位销117,且与定位销117配合设置。由此,可通过上述的定位销117和定位孔177将电路板170固定在底座110上。
在一些示例中,电路板170为包括为发光元件190供电和控制的电路结构的板状结构;电路板170可为印刷电路板(PCB)。
在一些示例中,由于可通过透光组件120将电路板170固定,因此透光组件120、底座110和容置空间220均不设置螺钉,从而可降低安装难度和成本。另外,由于不需要设置螺钉,在透光组件120上不用预留螺钉槽,可进一步提升照明模块发光面的利用率,也不需要在照明模块上加工螺钉孔,可降低该照明模块的不良率。
图8为根据本公开一实施例提供的一种照明模块的结构示意图;图9为本公开一实施例提供的照明模块在图8所示的AA区域的剖面示意图。
如图8和图9所示,该照明模块100包括底座110、透光组件120、密封结构140和密封组件130,例如,密封组件130可为密封条。底座110包括底板112和设置在底板112上且沿第一方向延伸的两个底座侧壁114,两个底座侧壁114相对设置并与底板112构成容纳槽210;透光组件120至少部分设置在容纳槽210内以在透光组件120和底板112之间形成容置空间220,透光组件120包括透光组件侧壁124,透光组件侧壁124设置在容纳槽210内并与两个底座侧壁114相对设置;密封结构140位于透光组件120和底板112之间,并且至少分别位于两个底座侧壁114在第一方向上的两个端部1140,也就是说,除了两个底座侧壁114在第一方向上的两个端部1140,密封结构140还可设置在其他位置以加强密封性;密封条130至少部分设置在对应设置的透光组件侧壁124和底座侧壁114之间,密封条130和透光组件侧壁124与底座侧壁114 分别紧密接触,密封条130和密封结构140共同将容置空间密封。需要说明的是,上述的底座侧壁和透光组件侧壁均为具有一定厚度的结构,而并非仅仅为二维的表面;同样地,下文中的各种侧壁也均为具有一定厚度的结构,而并非仅仅为二维的表面。
在本公开实施例提供的照明模块中,容置空间内可设置发光元件,发光元件用于发光,而将容置空间密封可防止外界水氧腐蚀发光元件,从而可提高该照明模块的使用寿命。该照明模块可通过密封结构(例如,可固化胶体)将容置空间在第一方向上的两个侧面密封,并通过底座侧壁、透光组件侧壁和密封条实现将容置空间在垂直于第一方向的方向上的两个侧面密封,从而可实现将容置空间与外界环境的水氧隔绝,并且无需在透光组件的边缘上设置压框、卡扣或螺钉。由此,在照明模块的外围尺寸相同的情况下,该照明模块可增加容置空间的面积以设置更多的发光元件(例如发光二极管灯珠),从而可提高照明模块的发光面的利用率,并在照明模块的功率相同的情况下,提高照明亮度和发光效率。另外,由于无需在透光组件的边缘上设置压框、卡扣或螺钉等额外的固定结构,该照明模块还可降低产品的不良率、节省安装步骤、提升安装效率、并降低成本。值得注意的是,相对于密封条受到垂直于底板的力而处于压缩状态的情况,当密封条受到垂直于底座侧壁的力而处于压缩状态时,密封条在垂直于底座侧壁的方向上的尺寸较小,从而可进一步提高照明模块的发光面的利用率,并在照明模块的功率相同的情况下,提高照明亮度和发光效率。
另一方面,由于两个底座侧壁114均在底板112上沿第一方向延伸,两个底座侧壁114可相互平行设置。由此,可方便地采用型材挤压成型工艺制作该底座,从而可降低该底座的制作成本,进而降低该照明模块的制作成本。
例如,底座可选择塑料、铝等便于挤压成型的材料进行制作。当然,本公开实施例包括但不限于此,底座也可采用其他材料制作。
在本公开实施例提供的照明模块中,当密封条受到垂直于底座侧壁的力而处于压缩状态时,密封条与底座侧壁之间存在静摩擦力,从而使得该照明模块无需在透光组件的边缘上设置压框、卡扣或螺钉也可保证密封条和透光组件不容易从容纳槽脱出,并且该照明模块具有良好的密封效果。
在一些示例中,如图8和图9所示,透光组件120、底座110和容置空间220均不设置螺钉,从而可降低产品的不良率、节省安装步骤、提升安装效率、并降低成本。
在一些示例中,如图8和图9所示,透光组件120可为透镜组件,即包括至少一个透镜部122。当然,本公开实施例包括但不限于此,透光组件120可也为其他透光的部件。
在一些示例中,如图8和图9所示,透光组件侧壁124被配置为向密封条130施加朝向底座侧壁114的力,以使密封条130处于压缩状态,从而更加紧密地将容置空间在垂直于第一方向的方向上的两个侧面密封。
在一些示例中,密封条的邵氏硬度范围在25-40之间。密封条的邵氏硬度越大,密封条越硬,对密封条进行压缩所需要的力就越大,当密封条被压缩而产生的反弹力容易将透光组件顶起,从而造成各种不良。而密封条的邵氏硬度越小,密封条越软,则密封条的形变量太大,反而容易导致密封效果不好。因此,本示例提供的照明模块通过将密封条的邵氏硬度范围设置在25-40之间,可具有较好的密封效果,同时,密封条不会产生较大的反弹力。另外,当密封条的邵氏硬度范围在25-40之间时,还提高密封条的寿命。
例如,密封条的邵氏硬度范围在25-30之间,从而可更好兼顾密封效果和较长的使用寿命。
在一些示例中,当密封条的邵氏硬度范围在25-40之间,第二间隔在垂直于底座侧壁的方向上的尺寸范围为2.1-2.3毫米时,通过多次实验,当密封圈在垂直于底座侧壁的方向上的压缩量的范围为0.4-0.6毫米,并且密封圈在垂直于底座侧壁的方向上的压缩率的范围在15%-22%时,密封条不会产生较大的反弹力,可同时满足不会将透光组件的边缘顶起,并且具有较好的防水效果。需要说明的是,本公开实施例包括但不限于此,当密封圈的压缩量和压缩率也可其他数值,只要保证一定防水效果即可。
在一些示例中,如图8所示,透光组件120还包括:防眩光结构325,位于两个底座侧壁114在第一方向上的两个端部1140所在的位置。例如,防眩光结构125位于透镜部112的外侧,即靠近透光组件120在第一方向上的边缘的一侧。由此,防眩光结构可起到防止眩光的作用。
例如,如图8所示,防眩光结构325可为从透光组件120远离底座110的表面向远离底座110的方向上凸起的凸块,以阻挡靠近透光组件120在第一方向上的边缘的发光元件的传播方向,从而起到防止眩光的作用。
图10A为根据本公开一实施例提供的一种照明模块在图8所示的AA区域沿第一方向的剖面示意图。如图10A所示,密封结构140为可固化胶体,可固 化胶体位于透光组件120和底板112之间,以将容置空间220在第一方向上的两个侧面密封。
图10B为根据本公开一实施例提供的另一种照明模块在图8所示的AA区域沿第一方向的剖面示意图。如图10B所示,透光组件120还包括阻挡侧壁128,设置在容置空间220在第一方向上的两个侧面所在的位置,从而防止密封结构进入容置空间220。
本公开一实施例还提供一种照明装置。图11为根据本公开一实施例提供的一种照明装置的结构示意图。如图11所示,该照明装置200包括上述的照明模块100。由此,该照明装置同样具有与上述照明模块的有益效果对应的有益效果,本公开在此不再赘述,具体可参见照明模块的相关描述。
在一些示例中,该照明装置可为路灯、体育场灯、机场灯等照明装置。
在一些示例中,如图11所示,该照明装置200包括多个照明模块100;多个照明模块100的底座110相互拼接,或者集成为一体,多个照明模块100的底座侧壁114之间设置有间隔,从而可减少照明模块之间热量的相互影响。也就是说,多个照明模块可共用一个底座,底座上设置有多个底座侧壁,从而构成多个容纳槽;相邻的底座侧壁之间具有间隔。
图12为根据本公开一实施例提供的一种照明装置的剖面示意图。如图12所示,该照明装置还包括延伸壁210、透明盖板220和模组卡扣230;延伸壁210从底座110的底板112向外延伸,透明盖板220位于透光组件120远离底板112的一侧,模组卡扣230被配置为将透明盖板220固定在延伸臂210上。由于该照明装置采用了一体式设计,从而便于安装;当该照明装置配备多个照明模块时,该照明装置可同时将多个照明模块放置到灯壳上,统一进行固定,从而可简化安装过程,省时省力。
例如,如图12所示,模组卡扣230包括上边2301、下边2302和将上边2301和下边2302相连的侧边2303;上边2301位于透明盖板230远离底板112的一侧,且位于透明盖板230的边缘,下边2302位于延伸壁210远离透明盖板230的一侧;侧边2303将上边2301和下边2302连接,以使得上边2301和下边2302可分别对透明盖板230和延伸壁210施加压力,以将透明盖板220固定在延伸臂210上。
例如,照明装置可包括多个模组卡扣,间隔设置在照明装置的边缘。当然,本公开实施例包括但不限于此,照明装置也可仅包括一个模组卡扣,围绕照明 装置的边缘设置。
例如,透明盖板230可为玻璃基板,塑料基板或其他透明基板。当透明盖板230为玻璃基板时,可同时具有较高的强度和光透过率,并且可以起到自清洁作用。
例如,透明盖板230上可设置防眩光图案,从而防止眩光现象的发生。例如,防眩光图案可包括丝印。
图13为根据本公开一实施例提供另一种照明装置的结构示意图。如图13所示,该照明模块还包括散热器180;散热器180设置在底板112远离透光组件120的一侧;散热器180包括多个散热鳍片182。散热器180上设有缺口区域184,缺口区域184可设置过线孔1841,过线孔用于安装照明模块100的电源线。
例如,相邻两个过线孔1841可通过凹槽1842连通,凹槽1842可设置导电结构并填充密封胶,从而实现将多个照明模块100的电源线进行串联、并联等连接,最终只引出两条导线(正负连接线),从而节约成本。而凹槽1842中填充的密封胶可对过线孔进行防水密封,又可以防止电线外露被损坏。
图14为根据本公开一实施例提供的另一种照明装置的结构示意图。如图14所示,该照明装置200包括多个照明模块100,多个照明模块100共用散热鳍片182,通过散热鳍片182将多个照明模块100连接起来,成为一结构;例如,多个照明模块100与多个子散热板1860一一对应设置,相邻的子散热板1860间隔设置,且通过散热鳍片182相连。图15为根据本公开一实施例提供的另一种照明装置的结构示意图。如图15所示,散热器180包括散热板186,散热板186可包括多个子散热板1860,例如,相邻的两个子散热板1860的侧面相连,照明装置200包括多个照明模块100,多个照明模块100与多个子散热板1860一一对应设置,各照明模块100的底座110固定在对应的子散热板1860上。
在一些示例中,如图15所示,散热板186为一体成型的单一部件。
在一些示例中,如图15所示,各照明模块100的底座110与对应的子散热板1860可集成为一体,从而可降低照明模块的结构复杂度。
在一些示例中,如图15所示,各子散热板1860远离透光组件120的一侧设置有多个散热鳍片182。
在一些示例中,如图15所示,各散热鳍片182上设置有多个散热缺口1825。 散热缺口1825使得散热鳍片182可便于喷塑,并且散热缺口1825可利于空气流通,从而进一步增强散热器180的散热能力。
在一些示例中,如图15所示,散热板186与多个散热鳍片182为压铸一体成型的一体件。由此,散热板186与散热鳍片182之间的导热能力更强,从而可增强散热器180的散热能力。
在一些示例中,如图15所示,各子散热板1860包括两个长边1861和两个短边1862,两个短边1862分别设置有固定部1865,固定部1865被配置为与外部灯壳相连。
在一些示例中,如图15所示,各子散热板1860上设置有过线孔1841。过线孔1841用于安装照明模块100的电源线。
图16为本公开一实施例提供的另一种照明装置的结构示意图。如图16所示,过线孔1841之中还可设置密封塞142,密封塞142穿过过线孔1841,并具有允许走线通过的通孔1420。
在一些示例中,如图16所示,照明装置200还包括:多个电源线270,与过线孔1841一一对应设置,各电源线270的第一端穿设于对应的密封塞142的通孔1420之中。由此,电源线270的第一端可通过密封塞142与照明模块100进行相连,并具有较高的防水性能。
在一些示例中,如图16所示,散热板186远离透光组件120的一侧设置有连通槽1842,连通槽1842将多个子散热板1860的多个过线孔1841相连,多个电源线270的第二端通过连通槽1842汇聚并具有一个引出端274,例如,多个电源线270可在连通槽1842中进行串联、并联等连接,最终引出上述的引出端274(正负连接线),从而节约成本,并且使得电源线更容易密封。
在一些示例中,如图16所示,照明装置200还包括螺纹管280,螺纹管280固定在多个过线孔1841中任意一个的周边,引出端274穿过螺纹管280,并通过螺纹管280进行紧固。

图17为根据本公开一实施例提供的另一种照明装置的结构示意图。如图17所示,该照明装置200可为一种灯具,包括多个照明模块100和灯壳250。多个照明模块100的底座110与灯壳250可一体成型;并且,相邻的照明模块100之间设有间隔,从而可降低模块之间热量的相互影响;另外,灯壳250内 可设置多种便于实现自动化生产的定位结构,从而可提高安装效率和降低成本。
本公开一实施例还提供一种照明模块的组装方法,该照明模块可为上述任一示例提供的照明模块。图18为根据本公开一实施例提供的一种照明模块的组装方法的流程图。如图18所示,该照明模块的组装方法包括以下步骤S601-S603。
步骤S601:将密封圈套设在透光组件侧壁的外侧。
步骤S602:将底座和透光组件定位。
步骤S603:向透光组件施加向底座的力以使得密封圈设置在透光组件侧壁和底座侧壁之间以将透光组件侧壁与底座侧壁之间的间隔密封。需要说明的是,这里虽然向透光组件施加向底座的力,但是使得密封圈处于压缩状态的力并非向透光组件施加向底座的力,而是透光组件侧壁和底座侧壁之间大致垂直于底座侧壁的力。
在本公开实施例提供的照明模块的组装方法中,可采用平板工装从上向下压透光组件,从而向透光组件施加向底座的力。在压透光组件的过程中,透光组件四周的密封圈受底座侧壁挤压产生一定的压缩量,从而达到密封效果。并且,该组装方法具有步骤简单、组装效率较高,成本较低等优点。
在一些示例中,当透镜侧壁包括第四侧壁,位于第一侧壁远离第二侧壁的一侧,底座侧壁包括第五侧壁,第四侧壁和第五侧壁相对间隔设置,并具有第四间隔,第四间隔大于第一间隔,第四间隔与第一间隔和第二间隔相连通时,组装方法还包括:在第四间隔设置密封胶,以将第一间隔和第二间隔密封,从而起到双重密封的效果。
在一些示例中,在向透光组件施加向底座的力以使得密封圈设置在透光组件侧壁和底座侧壁之间以将透光组件侧壁与底座侧壁之间的间隔密封之前,该组装方法还可对底座进行加热(例如,温度160-170摄氏度,时间为4-5分钟),使得底座有一定的膨胀,从而进一步降低组装难度。
在一些示例中,当该照明模块包括电路板时,该组装方法还包括将电路板通过定位孔和底板上的定位销固定;当向透光组件施加向底座的力以使得密封圈设置在透光组件侧壁和底座侧壁之间以将透光组件侧壁与底座侧壁之间的间隔密封时,透镜组件可将电路板压紧在底座上。
本公开一实施例还提供一种照明模块。参见图1A-图7,该照明模块包括: 底座110、透光组件120和电路板170。底座110包括底板112和设置在底板112上的底座侧壁114,底座侧壁114与底板112围成容纳槽210;透光组件120至少部分设置在容纳槽210内以在透光组件120和底板110之间形成容置空间220,透光组件120包括透光组件侧壁124,透光组件侧壁124与底座侧壁114相对间隔设置;电路板170设置在容置空间220之内。透光组件120的至少一部分抵住电路板170的远离底板112的表面,以在垂直于底板112的方向上将电路板170固定。
在本公开实施例提供的照明模块中,通过将透光组件的至少一部分抵住电路板的远离底板的表面,从而可在垂直于底板的方向上将电路板固定在底板上。所以,该照明模块不设置螺钉,从而一方面可降低组装难度并提高组装效率,另一方面还可降低成本。另外,该照明模组不设置螺钉,仅通过压合就可完成组装,从而便于进行自动化组装。
在一些示例中,参见图1A-图7,电路板170包括第一定位结构177,例如,定位孔177,底座110包括第二定位结构117,例如,定位销117;第一定位结构177与第二定位结构117彼此配合,以在平行于底板112的方向上将电路板170固定。
在一些示例中,参见图1A-图7,照明模块还包括至少一个发光元件190,设置于电路板170上,且被配置为朝向透光组件120发光,透光组件120包括至少一个透镜部122,至少一个透镜部122与至少一个发光元件190一一对应设置。
在一些示例中,参见图1A-图7,透光组件120包括阵列排布的多个透镜部122,多个透镜部122的至少一个的周围设置有抵住电路板170的部分。
在一些示例中,参见图1A-图7,多个透镜部122的每个的周围均设置有抵住电路板170的部分。
例如,参见图1A-图7,透光组件120的抵住电路板170的部分与电路板170直接接触。
例如,参见图1A-图7,容置空间220内不包括螺钉,从而可降低安装难度和成本。
例如,上述的发光元件可为发光二极管。当然,本公开实施例包括但不限于此,上述的发光元件也可为其他类型的发光二极管。以上仅为本公开的一些实施方式,但本公开的保护范围并不局限于此,基于上述的实施方式,本公开 可包括以下的技术方案:
