以下针对本发明实施例1提供的照明装置100内的各个元件及元件之间的连接关系作具体说明。
如图1至图3所示，底盘6大致呈长方体状，具有平板状底板61及自底板61四周垂直延伸形成的侧壁62。底盘6的宽度大于550mm，其可采用金属材料、塑料、导热塑料等。底盘6可安装在天花板等安装基础上。
面罩7罩在底盘6的一侧，其外表面具有一定的弧度，在其它可替换的实施方式中，面罩7的外表面也可以为平面。面罩7采用透光的材料制成，如亚克力等，其具有匀光的作用。面罩7与底盘6的连接可采用插接、卡接、螺丝连接等方式。在其它可替换的实施方式中，照明装置100内也可以不包括面罩7。
如图4至图6所示，光源模组50包括安装基座5、安装在安装基座5上的透镜1、安装在透镜1两端的挡板4、及收容在透镜1内的发光组件3，其中，透镜1完全覆盖安装基座5，因此发光组件3夹置于透镜1与安装基座5之间。在本实施例中，光源模组50设置为一组，且其两端位于底盘6横向侧壁的中部位置处，并沿底盘6纵向侧壁的纵向方向延伸，光源模组50的长度等于底盘6的纵向长度。在其它可替换的实施方式中，光源模组50的长度还可以为底盘6的1/2、2/3等其它长度。
安装基座5呈长条形，其底面贴合在底盘6上，在本实施例中，安装基座5为铝型材，或由其它散热性好的材料制成。安装基座5具有呈长方形的平板状基部51及自基部51的长边的两侧向透镜1方向弯折延伸形成的用于安装透镜1的一对安装部52，安装部52向彼此延伸并与基部51部分重叠。安装部52包括自侧边垂直延伸的连接部521及自连接部521倾斜延伸形成的夹置部522，夹置部522向基部51延伸形成若干间隔设置的肋部523，基部51和安装部52形成用于透镜1卡接固定的安装区域524，基部51位于安装区域524的部分设有若干个第一安装孔511。在其它可替换的实施方式中，可以不设置安装基座5，直接将透镜1安装在底盘6上。在本实施方式中，安装基座5内安装有若干个直条型的透镜1，若干个透镜1首尾抵接。在其它实施方式中，也可只安装一个直条型的透镜1。

透镜1为轴对称结构，其延伸方向为纵向30，与纵向30垂直的方向为横向20，中心轴10与该横向20和纵向30正交。透镜1在纵向30上的横截面均相同。
如图6所示，透镜1具有内表面11、外表面12、底表面13、及用于收容发光组件3的第一收容腔2，该第一收容腔2的壁面由透镜1的内表面11和安装基座5的底面围设形成。
内表面11的横截面呈锯齿状，包括向第一收容腔2方向凸出的第一入光面111、位于延伸进入第一收容腔2的一对第一齿角110及一对第二齿角110’，一对第一齿角110及一对第二齿角110’分别根据中心轴10对称设置，第二齿角110’的尖端比第一齿角110的尖端更接近底表面13。一对第一齿角110包含相对设置的第二入光面112和相对设置的底面115，一对第二齿角110’包含相对设置的第三入光面113及两个反射面114，第二入光面112为第一入光面111的相邻面，反射面114的相邻面分别为第三入光面113及侧壁面116，反射面114为第一收容腔2的底壁面。在本实施方式中，第一入光面111为曲面，第二入光面112和第二入光面113为平面，反射面114为曲面且向外凸出。在其它实施方式中，这三种入光面可以均为曲面，也可以均为平面。反射面114可以为曲面也可以为平面，且反射面114为全内反射面。
如图7和图8所示，外表面12包括位于中间顶部区域并彼此相对的第一出光面121、位于两个第一出光面121两侧并分别与相邻第一出光面121相交的第二出光面122、及由第二出光面122延伸至底表面13的第三出光面123，两个第一出光面121以中心轴10对称且呈V形结构，两个第一出光面121的相交处形成有圆弧倒角，即R角。第一出光面121可为曲面，也可以为平面。第二出光面122为平面，可以与中心轴10平行，也可以具有一定的斜度。第三出光面123为沿远离第一收容腔2方向凸出的曲面。
第一收容腔2包括第一收容区域21和第二收容区域22，第一收容区域21由第一入 光面111、相对设置的第二入光面112、底面115及第三入光面113围设形成，第二收容区域22由反射面114和侧壁面116围设形成。第一收容区域21收容发光单元32，第二收容区域22收容光源板31，在其它实施方式中，可将发光组件3都置于第一收容区域21内。第二齿角110’比第一齿角110更靠近光源板。
透镜1还包括一对立柱131结构，其由侧壁面116、侧壁面116所对应的外表面的部分、及底表面13构成，在本实施例中，连接部15由立柱131下端垂直向外延伸而出。
如图9所示，准直入射在R角上的光线经R角折射后出射；入射到第一出光面121的光线大部分被反射，小部分被折射或直接透射，具体的，直接入射在第一入光面111上的一部分光经第一出光面121反射到第二出光面122并且被第二出光面122折射后出射，另一部分光线经第一出光面121直接出光。第一出光面121的外表面可进行轻磨砂处理，使得经第一出光面121直接出光的这部分光线折射后出光或直接透射出光。如图10所示，直接入射在第二入光面112的光线折射到第三出光面123并被该第三出光面123折射后出射。如图11所示，准直入射到第三入光面113的光线经反射面114反射到第三出光面123折射后出射。本发明实施例的照明装置，其内的透镜的内表面锯齿状的入射结构的设计，外表面以折反面与折射面结合的出射方式的设计，使得照明装置出射的光线覆盖角度大，且利用这种光路分段式的设计，使得不同阶段能量分别打在目标位置，通过叠加从而达到增大出光均匀度的效果。宽度不足32mm的透镜1，就能使宽度大于550mm的照明装置100均匀出光，也就是说，在透镜1与底盘6的宽度比小于0.06的条件下，透镜1的出光角度都足使整个照明装置100均匀出光，通过更少数量的透镜，实现更大体积的灯具的均匀照射面积，降低了成本。
实施例2
参见图12所示，本发明实施例2提供一种应用于本发明实施例1提供的照明装置100内的一种透镜1a，该透镜1a与实施例1的透镜1的结构类似，也呈直线型，且其横截面也根据中心轴10呈轴对称结构。该透镜1a具有内表面11、外表面12、底表面13、及用于收容发光组件(未图示)的第一收容腔2，该第一收容腔2的壁面为透镜1a的内表面11。在本实施方式中，第一收容腔2包括第一收容区域21和第二收容区域22，第一收容区域21收容发光组件(未图示)，第二收容区域22收容光源板(未图示)，在其它实施方式中，可将发光组件(未图示)都置于第一收容区域21内。

参见图20所示，本发明实施例6提供的一种可应用于本发明实施例1提供的照明装置100内的一种透镜1f，呈曲线形。该透镜1f具有用于收容发光组件(未图示)的第一收容腔(未标示)，其壁面为透镜1f的内表面(未标示)。
其内表面的形状可以为上述实施例1至3中任意一种形状。
上述6个实施例中的透镜，内表面锯齿状的入射面结构设计，外表面的反射面与折射面结合的出射面的结构设计，使得出射的光线覆盖角度大，且利用这种光路分段式的设计，使得不同阶段能量分别打在目标位置，通过叠加从而达到增大出光均匀度的效果。
以上所述的具体实例，对本发明的目的、技术方案和有益效果进行了进一步详细说明，所应理解的是，以上所述仅为本发明的具体实施例而已，并不用于限制本发明，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
