为了使本技术领域的人员更好地理解本发明中的技术方案,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅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,都应当属于本发明保护的范围。
实施例1
本发明实施例1提供一种照明装置,以解决现有技术中难以确保上述照明装置中包含的各个光源发射的光透过各个透镜后得到的出光光型一致的问题。
配合参照图1和图2所示,本实施例的照明装置100可以包括壳体10、设置于所述壳体10内的光源模组40及与所述光源模组40配合的透镜组合30。
光源模组40可以包括基板41、设置于基板41的第一表面410上的若干呈环状排布的第一光源42,设置于基板41的第一表面410上的一个或多个第二光源43。其中,第二光源43位于上述第一光源42的环心的位置。上述第一光源42、第二光源43可以是发光二极管(Light Emitting Diode,LED)、或其他类型的发光器。上述光源模组40还包括设置于所述基板41上的电子器件(未图示)。所述光源模组40可以集成用以驱动该光源模组40的驱动模组(未图示),该驱动模组可以集成在基板41的第一表面410上、或与该第一表面410相背设置的第二表面上。
相应地,透镜组合30可以包括用以与上述光源模组40的基板41相贴合的基部33,连接于基部33的且呈圆环状的第一透镜32,及连接于基部33的且位于所述第一透镜32的环心的第二透镜31。其中,上述第一透镜32是与上述光源模组的第一光源42相配合设置的,上述第二透镜31是与上述光源模组40的第二光源43相配合设置的。
值得述及的是,上述透镜组合30是包含至少两个透镜的透镜部件,所述至少两个透镜可以是一体设置的或非一体设置的,并且该透镜组合30包含的透镜的数量也不受限于此。本申请实施例中,上述第二透镜31可以是圆环状或非圆环状(比如点状)。优选地,若第一透镜32、第二透镜31均是圆环状,则第一透镜32的环心(即透镜所呈现的圆环的环心)与第二透镜31的环心是重合;若第一透镜32是圆环状,而第二透镜31是点状,则该第二透镜31的位置可以布设于该第一透镜32的环心上,再进一步地,如果第二透镜31是圆点状,则可以将该第二透镜31的圆点中心设成与上述第一透镜32的环心重合。当然,本申请可行的实施例中,上述第一透镜32、第二透镜31的相互位置并不作限制。
优选地,为进一步提升照明装置100的发光效果及美观性,上述照明装置100还可以包括设置于壳体10内且呈环状设置的反射部件20,所述反射部件20环绕于所述第一透镜32的外侧。该反射部件20包括呈弧形状的反射面21及用以在安装时供透镜组合30穿过的开口22。上述反射部件20可以采用镜面反射、或漫反射、或吸收类型的反射等。
本发明实施例中,壳体10可以包括底壁12及连接于底壁12的侧壁11,所述底壁12上设置有多个固定螺孔13,相应地,光源模组40的基板41上设置有多个定位部45。透镜组合30的基部33上设置有多个固定通孔34。壳体10的侧壁11上还设有多个自所述侧壁11向内凸伸形成的扣持部110。反射部件20还设置有用以与壳体10的侧壁11相贴合的安装壁23,其自反射部件20的上表面24向下延伸为竖直侧壁并环绕设置于反射部件20的反射面21外周。该安装壁23上设置有多个用以与上述扣持部110相配合的扣持孔230。
在安装过程中,首先将光源模组40放置于壳体10的底壁12上,并且在放置的过程中,将上述光源模组40的多个定位部45分别套合于上述底壁12上的多个固定
螺孔13,随后将所述透镜组合30安置于基板41设有第一光源42的第一表面410上。同样地,在放置过程中可以将透镜组合30的多个固定通孔34与多个固定螺孔13的位置对应起来,通过与固定螺孔13配合的螺栓70将上述光源模组40、透镜组合30固定于壳体10内。当然,上述光源模组40、透镜组合30之间的结合方式并不限于此,还可以是胶粘、铆接等。随后,将反射部件20放置于透镜组合30的基部33上,且其反射面21环绕设置于透镜组合30的第一透镜32的***,并且通过相互配合的扣持部110、扣持孔230实现该反射部件20与壳体10的相互固定。组配后,反射部件20的上表面24与壳体10的上表面平齐,且反射面21与壳体10的侧壁11之间形成有用以安置所述光源模组40的电子器件(未图示)的容纳空间25。本实施例通过将电子器件分布于上述容纳空间25内,从而可以有效降低照明装置的厚度,使得照明装置更加轻薄。其中,该电子器件可以包括驱动模组(未图示),从而将驱动模组也安置于所述容纳空间25内。当然,上述驱动模组也可以与光源模组一体集成在基板41上。同理,上述反射部件20与壳体10的结合方式并不限于此,还可以是胶粘、铆接等。值得一提的是,照明装置100还包括用以安装于所述壳体10底部的导线60,该导线60与所述光源模组40电性连接。
配合参照图3至图5所示,其中,定义图3至图5所示的截面是沿着第一剖面线(即图1中所示的A-A方向)进行剖面得到的,所述第一剖面线通过所述第一透镜32的环心。第一透镜32包括呈环状的第一透镜主体320以及自所述基部33向内凹陷形成的第一凹槽323,第二透镜31包括第二透镜主体310以及自所述基部33相内凹陷形成的第二凹槽313。上述第一透镜32具有相背设置的第一入光面322和第一出光面324,当透镜组合30和光源模组40安装后,由于上述第一凹槽323的存在,上述第一入光面322与上述第一表面410(参图2所示)之间便可形成用以安置上述第一光源42的第一空腔321。同样地,上述第二透镜31也具有相背设置的第二入光面312和第二出光面314,由于上述第二凹槽313的存在,当透镜组合30和光源模组40安装后,该第二透镜31的第二入光面312与上述第一表面410之间形成用以安置上述第二光源43的第二空腔311。本发明实施例可以将光源模组40的呈环状分布的第一光源42安置于上述第一透镜32的第一空腔321内,相比于现有技术,可以在照明装置100的有限的空间内设置更多数量的光源,进而提升照明装置100的发光效率。此外,透镜组合30可以根据需要的光通量的大小,相应地调整位于第一透镜32内的第一光源42的数量。并且上述透镜组合30可以共用多种封装,兼容性佳,基板41上的光源的排布方式更加灵活。
另外值得说明的是,本发明实施例中,所述第一透镜32的第一入光面322和第一出光面324设置为曲面,并且,所述第一入光面322的曲率半径大于所述第一出光面324的曲率半径。同样地,所述第二透镜31的第二入光面312和第二出光面314设置为曲面,并且所述第二入光面312的曲率半径大于所述第二出光面314的曲率半径。这样,当照明装置的光源安装到透镜组合30内时,光源所发出的入射光线完全透过该透镜组合30来向外发射,上述曲面形状的第一透镜32、第二透镜31可以使得发光效率及配光效果更佳。由于本发明实施例通过将光源模组40的基板41和透镜组合30的基部33相互贴合,来形成一个由基板41和基部33围成的第一空腔
或第二空腔,故,各个第一光源、第二光源完全收容于上述第一空腔321或第二空腔311内,这样可以确保入射光线可以全部从透镜组合30透过并照射到照明装置外,发光效率高。
参见图4,为了使得照明装置上的各个光源透过上述透镜组合30后的配光效果一致(即出光光型一致),本实施例中,所述第一透镜32沿着第一剖面线得到的第一截面的面型与所述第二透镜31沿着第一剖面线得到的第二截面的面型并不一致。本实施例中,上述第一透镜32在所述基部33的厚度方向上的高度与所述第二透镜31在所述基部33的厚度方向上的高度不相等。也就是说,若定义第一透镜32在所述基部33的厚度方向上的高度是:第一透镜32的第一顶部325到基部33的第一垂直距离;定义第二透镜31在所述基部33的厚度方向上的高度是:第二透镜31的第二顶部315到基部33的第二垂直距离,则上述第一垂直距离可以大于或小于上述第二垂直距离。当然,在优选的实施例中,将上述第一垂直距离设置成大于上述第二垂直距离。特别参阅图4及图9,上述第一透镜32的第一入光面322在所述基部33的厚度方向上的最大高度略大于所述第二透镜31的第二入光面312在所述基部33的厚度方向上的最大高度,且均与基部33的厚度大致接近。
参图6所示,其为第一透镜上设有第一入光面一侧的结构示意图。在实际使用过程中,照明装置可能出现少量光源不点亮的状况,这一状况可能导致人眼通过透镜观察该照明装置时出现颗粒感。为了祛除上述颗粒感,并提升视觉效果,本实施例可以在所述第一透镜32的第一入光面322、或者第一出光面324上形成有呈凹凸状的祛颗粒感层35。该祛颗粒感层35可以是任意形式的一体形成于所述第一透镜32的第一入光面322和/或第一出光面324上的凹凸状结构,比如:“V”型结构。当然,上述呈凹凸状的祛颗粒感层35也可以同时设置于第一入光面322及第一出光面324上。同样的原理,上述祛颗粒感层35也可以形成于第二透镜31的第二入光面或第二出光面上。
参照图7a、7b所示,其为本发明实施例中光源模组上第一光源的排布示意图。其中,可以看出环形排布的第一光源42的数量可以根据需要进行调整。定义第一光源42的分布角度为:相邻的两个第一光源42与环心之间的连线所成角度。则,图7a中第一光源42的数量是20个,其分布角度为18°,图7b中第一光源42的数量是40个,其分布角度为9°。本发明实施例中,为了消除环状的第一透镜32的拉伸方向不能控光而产生的光斑现象,所述第一透镜32的第一入光面322或第一出光面324上可以形成有凹凸结构,该凹凸结构可以包括通过蚀纹工艺形成的蚀纹结构、通过磨砂工艺形成磨砂结构中的一种或多种。本实施例中,通过上述蚀纹结构或磨砂结构,可以使得上述第一光源42产生的入射光线在透过该第一透镜后得到的出射光线的分散角度达到一定的要求。
参照图8所示,其为本发明实施例中配光曲线示意图。关于上述分散角度的定义,是指:当一束平行光线入射到所述第一透镜32后,确定出射光强度最大值的一半所对应的1/2强度的出射光线,则所述分散角度是指两个1/2强度的出射光线所成的夹角。举例而言,在图8的配光曲线中,若出射光线的最大强度是1(最大光强的光线集中于第一透镜的法线位置),那么1/2强度的出射光线分布于上述法线位置的
±2.5°的位置,故,此时所述分散角度为5°。
为了得到均匀的光斑,本实施例中,所述蚀纹结构或磨砂结构使得第一透镜32的分散角度与所述第一光源42的分布角度正相关。也就是说,当分布角度变小时,相应地需要减小上述分散角度的大小,而当分布角度变大时,相应地需要增大上述分散角度的大小。例如:分布角度为18°时,上述分散角度可以是12°,分布角度为9°时,上述分散角度可以是6°。
参照图9所示,为本发明中光源的入射光线通过透镜的光路图。该透镜的入光面和出光面都对光线具有汇聚作用。其中,定义光源的入射光线与法线的夹角为a,定义光源的入射光线通过入光面折射得到的光线与法线的夹角为b,定义上述通过入光面折射得到的光线再通过出光面折射得到的光线与法线的夹角为c。一般地,上述夹角a为0°~90°,经过入光面折射后,上述夹角b汇聚为0°~65°,在经过出光面折射后,上述夹角c汇聚为0°~50°。参照图10所示,为第一、第二光源发射的光透过透镜组合的光路图。若定义出光光型是光源生成的光线在透过上述透镜(第一透镜32或第二透镜31)折射后的出射光线与法线的最大夹角。譬如,第一透镜32内的第一光源42发射的光线在通过第一透镜32的第一入光面322和第一出光面324折射后得到的出射光线与法线的最大夹角是β1,第二透镜31内的第二光源43发射的光线在通过第二透镜31的第二入光面和第二出光面折射后得到的出射光线与法线的最大夹角是β2。故,第一光源42发射的光透过第一透镜32后的出光光型与第二光源43发射的光透过第二透镜31后的出光光型一致,可以理解成上述夹角β1与上述夹角β2相等。可见,由于在本发明实施例中,第一透镜32设置成圆环状,第二透镜31设置成点状,若将圆环状的第一透镜32对应的第一截面的截面面型设置成与点状的第二透镜31对应的第二截面的截面面型相同,则难以达到第一光源42透过第一透镜32后的出光光型与第二光源43透过第二透镜31后的出光光型完全一致的效果。为此,本实施例中,将上述第一透镜32对应的第一截面的截面面型设置成与上述第二透镜31对应的第二截面的截面面型不一致,从而实现两者的配光光型相同。基于以上内容,本发明通过将第一透镜32和第二透镜31的截面面型设置成不一致,从而达到第一透镜32和第二透镜31具备相同的配光效果(即上述夹角β1与上述夹角β2相等)。通常,由于制造工艺的不同,点状的第二透镜31是旋转对称的面型,而环状的第一透镜32不是旋转对称的面型,假设入射光线在透过点状的第二透镜31后得到的出射光线与法线的最大夹角β2是60°,如果将环状的第一透镜32的截面面型设置成与该第二透镜31的截面面型相同,则可能入射光线在透过这样的第一透镜32后得到的出射光线与法线的最大夹角β2通常大于60°(比如70°~80°)。基于上述原因,本发明为了使得环状的第一透镜32与点状的的第二透镜31具备相同的配光效果,则会通过在工艺上改变上述第一透镜32的截面面型,来使得入射光线在透过第一透镜32后得到的出射光线与法线的最大夹角β2维持在60°。本发明各实施例中,改变第一透镜32的截面面型的方式可以包括改变第一透镜32的第一入光面322和第一出光面324的曲率,或改变第一透镜32的高度,或改变第一透镜32的宽度等,本发明不作限定。
综上,本发明实施例1的照明装置使用的透镜组合,由于可以使得安置于第一
安置空间内的第一光源所发射的入射光线在经过第一入光面及第一出光面后得到的出光光型,与安置于第二安置空间内的第二光源所发射的入射光线在经过第二入光面及第二出光面后得到的出光光型一致,从而可以确保该透镜组合中的第一透镜和第二透镜能够具备同样的配光效果,并且避免为每个光源分别设置一个罩设于该光源上的透镜,进而改善照明装置的照明效果。
实施例2
配合参照图11至图13所示,本实施例的照明装置100’可以包括壳体10’、与壳体10’连接的面环50’、设置于所述壳体10’内的光源模组40’及与所述光源模组40’配合的透镜组合30’。
光源模组40’可以包括基板41’、设置于基板41’的第一表面410’没找到标号上的若干呈环状排布的第一光源42’,设置于基板41’的第一表面410’上的一个或多个第二光源43’。其中,第二光源43’位于上述第一光源42’的环心的位置。上述第一光源42’、第二光源43’可以是发光二极管(Light Emitting Diode,LED)、或其他类型的发光器。上述光源模组40’还包括设置于所述基板41’上的电子器件(未图示)。所述光源模组40’可以集成用以驱动该光源模组40’的驱动电源组件(未图示),该驱动电源组件可以集成在基板41’的第一表面410’上、或与该第一表面410’相背设置的第二表面上。当然,也可以将驱动电源组件外置,如图14所示,照明装置100’还包括驱动电源组件80’,驱动电源组件80’通过导线60’与壳体10’内的光源模组40’电性连接。
相应地,透镜组合30’可以包括用以与上述光源模组40’的基板41’相贴合的基部33’,连接于基部33’的且呈圆环状的第一透镜32’,及连接于基部33’的且位于所述第一透镜32’的环心的第二透镜31’。其中,上述第一透镜32’是与上述光源模组40’的第一光源42’相配合设置的,上述第二透镜31’是与上述光源模组40’的第二光源43’相配合设置的。
值得述及的是,上述透镜组合30’是包含至少两个透镜的透镜部件,所述至少两个透镜可以是一体设置的或非一体设置的,并且该透镜组合30’包含的透镜的数量也不受限于此。本申请实施例中,上述第二透镜31’可以是圆环状或非圆环状(比如点状)。优选地,若第一透镜32’、第二透镜31’均是圆环状,则第一透镜32’的环心(即透镜所呈现的圆环的环心)与第二透镜31’的环心是重合;若第一透镜32’是圆环状,而第二透镜31’是点状,则该第二透镜31’的位置可以布设于该第一透镜32’的环心上,再进一步地,如果第二透镜31’是圆点状,则可以将该第二透镜31’的圆点中心设成与上述第一透镜32’的环心重合。当然,本申请可行的实施例中,上述第一透镜32’、第二透镜31’的相互位置并不作限制。
优选地,为进一步提升照明装置100’的发光效果及美观性,上述照明装置100’还可以包括设置于壳体10’和面环50’之间且呈环状设置的反射部件20’,所述反射部件20’环绕于所述第一透镜32’的外侧。该反射部件20’包括呈倾斜状的反射面21’、位于反射面21’两端且呈水平状的上端面23’和下端面25’、及用以在安装时供透镜组合30’穿过的开口22’。其中,反射面21’包括第一反射面211’
和第二反射面212’,第一反射面211’的面型为斜面,第二反射面212’的面型为曲面。下端面25’、第一反射面211’、第二反射面212’、上端面23’依次连接。上端面23’上设置有若干个导向槽24’,下端面25’上设置有一圈收容槽251’。收容槽251’内收容有垫圈26’,用以提高该照明装置100’的防水密封性。上述反射部件20’可以采用电镀镜面反射、或漫反射、或吸收类型的反射等,以实现眩光控制,另外,反射面21’采用部分曲面部分直面的面型,使得光斑更加均匀。
本发明实施例中,壳体10’可以包括底壁12’及连接于底壁12’的侧壁11’,所述底壁12’上设置有多个固定螺孔13’和定位柱14’,相应地,光源模组40’的基板41’上设置有多个通孔(定位部)44’。透镜组合30’的基部33’上设置有多个固定通孔34’。壳体10’的侧壁11’上还设有多个自所述外表面向端面延伸形成的固定螺孔15’,且侧壁’上还连接有两个卡簧16’。
面环50’包括侧壁51’和连接于侧壁51’的环面52’,侧壁51’的内表面设有若干个定位柱53’,每个定位柱53’的两侧均设有筋条54’,定位柱53’与固定螺孔15’相配合,筋条54’与导向槽24’的两侧配合用以在组装反射部件20’时起导向作用。内表面靠近环面52’处还设有多个凸起55’,反射部件20’的端面23’定位于面环50’的环面52’和凸起55’之间。
在安装过程中,首先将光源模组40’放置于壳体10’的底壁12’上,并且在放置的过程中,将上述光源模组40’的多个通孔(定位部)44’分别套合于上述底壁12’上的多个固定螺孔13’和定位柱14’,随后将所述透镜组合30’安置于基板41’设有第一光源42’的第一表面410’上,在放置过程中将透镜组合30’的多个固定通孔34’与光源模组40’的多个通孔44’的位置对应,再通过与固定螺孔13’配合的螺栓(未图示)将上述光源模组40’、透镜组合30’固定于壳体10’内。当然,上述光源模组40’、透镜组合30’之间的结合方式并不限于此,还可以是胶粘、铆接等。随后,将反射部件20’放置于透镜组合30’的***,通过螺栓70’穿过固定螺孔16’并收容在定位柱53’中实现壳体10’、反射部件20’和面环50’之间的连接与固定。同理,上述反射部件20’与壳体10’的结合方式并不限于此,还可以是胶粘、铆接等。配合参照图15至图17所示,其中,定义图15至图17所示的截面是沿着第二剖面线(即图11中所示的B-B方向)进行剖面得到的,所述第二剖面线通过所述第一透镜32’的环心。第一透镜32’包括呈环状的第一透镜主体320’以及自所述基部33’向内凹陷形成的第一凹槽323’,第二透镜31’包括第二透镜主体310’以及自所述基部33’相内凹陷形成的第二凹槽313’。上述第一透镜32’具有相背设置的第一入光面322’和第一出光面324’,当透镜组合30’和光源模组40’安装后,由于上述第一凹槽323’的存在,上述第一入光面322’与上述第一表面410’(参图12所示)之间便可形成用以安置上述第一光源42’的第一空腔321’。同样地,上述第二透镜31’也具有相背设置的第二入光面和第二出光面,由于上述第二凹槽313’的存在,当透镜组合30’和光源模组40’安装后,该第二透镜31’的第二入光面与上述第一表面410’之间形成用以安置上述第二光源43’的第二空腔311’。本发明实施例可以将光源模组40’的呈环状分布的第一光源42’安置于上述第一透镜32’的第一空腔321’内,在本实施例中,第一光源42’设置
为一环的形式,在其它可替换的实施例中,比如图18所示,第一光源42’设置为两环或多环的形式,以此可以在照明装置100’的有限的空间内设置更多数量的光源,进而提升照明装置100’的发光效率。此外,透镜组合30’可以根据需要的光通量的大小,相应地调整位于第一透镜32’内的第一光源42’的数量。并且上述透镜组合30’可以共用多种封装,兼容性佳,基板41’上的光源的排布方式更加灵活。
另外值得说明的是,本发明实施例中,所述第一透镜32’的第一入光面322’和第一出光面324’设置为曲面,并且,所述第一入光面322’的曲率半径大于所述第一出光面324’的曲率半径。这样,当照明装置的光源安装到透镜组合30’内时,光源所发出的入射光线完全透过该透镜组合30’来向外发射,上述曲面形状的第一透镜32’可以使得发光效率及配光效果更佳。由于本发明实施例通过将光源模组40’的基板41’和透镜组合30’的基部33’相互贴合,来形成一个由基板41’和基部33’围成的第一空腔321’或第二空腔311’,故,各个第一光源42’、第二光源43’完全收容于上述第一空腔321’或第二空腔311’内,这样可以确保入射光线可以全部从透镜组合30’透过并照射到照明装置外,发光效率高。
参见图15,为了使得照明装置上的各个光源透过上述透镜组合30’后的配光效果一致,本实施例中,所述第一透镜32’沿着第二剖面线得到的第一截面的面型与所述第二透镜31’沿着第一剖面线得到的第二截面的面型并不一致。本实施例中,上述第一透镜32’在所述基部33’的厚度方向上的高度与所述第二透镜31’在所述基部33’的厚度方向上的高度不相等。也就是说,若定义第一透镜32’在所述基部33’的厚度方向上的高度是:第一透镜32’的第一顶部325’到基部33’的第一垂直距离;定义第二透镜31’在所述基部33’的厚度方向上的高度是:第二透镜31’的第二顶部315’到基部33’的第二垂直距离,则上述第一垂直距离可以大于或小于上述第二垂直距离。当然,在优选的实施例中,将上述第一垂直距离设置成大于上述第二垂直距离。
如果环形的第一透镜32’的外表面是光滑壁面,则其只有径向X1的光线控制,没有切线方向X2的光线控制,经反射部件20’反射后的光线容易形成亮圈,影响光斑的均匀性。因此,在本实施例中,采用如图19所示的透镜组合30’,可避免亮圈的出现,提升视觉效果。本实施例所述第一透镜32’的第一出光面324’的外表面上设置有多条彼此平行的凸棱321’,所述若干凸棱321’沿所述第一透镜32’的延伸方向均匀间隔排布,且每一凸棱321’沿所述第一透镜32’的外表面突起。通过沿延伸方向设置多条等分的凸棱321’,将切线方向X2的光线进一步分散实现光斑均匀。当然,上述凸棱321’也可以同时设置于第一入光面322’及第一出光面324’上。同样的原理,也可以在第二透镜31’的第二入光面和/或第二出光面上设置多个等分的凸棱321’。于本发明优选实施例中,凸棱321’的曲率与所设置的入光面或出光面一致。
如图21所示,第一透镜32的第一出光面324为光滑壁面,光线由第一透镜32的第一入光面322进入,由第一出光面324出射;如图22所示,第一透镜32’的第一出光面324’上设有若干条棱条321’,光线由第一透镜32’的第一入光面322’进入,由第一出光面324’出射,将图22与图21中所示的光路作对比,第一透镜
32’相对于第一透镜32,由于在第一出光面324’上设置有棱条321’,射到不同的棱条321’上的光束,其内的光线以不同的入射角度经该棱条321’的折射作用后出射,从而将该光束分散出射,即出射光线被进一步散射,消除了原第一透镜32的切线方向X2不能控光而产生亮圈的问题。
第一入光面322’和第二入光面也可以采用蚀纹结构或磨砂结构,可以使得上述第一光源42’产生的入射光线在透过该透镜组合30’后得到的出射光线的光束角达到一定的要求。
综上,本发明实施例2的照明装置使用的透镜组合30’,通过将其中至少一个透镜的出光面上设置有若干连续的凸棱若干,避免了由该出光面出射的光线形成亮圈的情况,进一步提高光斑的均匀性,改善了照明装置的照明效果。
以上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。
