    • The present invention relates to a lens, a lens array and an illuminating device. The lens comprises a first surface and a second surface, wherein the first surface comprises: light incident surfaces, from which light enters the lens; and a total reflection surface, on which a part of light entering the lens is totally reflected, the second surface comprises a light emergent surface, wherein the light incident surfaces comprise a plurality of three-dimensional surfaces assigned to different light sources, a part of light from one light source enters the lens from one three-dimensional surface assigned to the one light source, and the other part enters the lens from one three-dimensional surface that is not assigned to the one light source. The lens has a compact structure and can uniformly mix colors.
    • 透镜,透镜阵列及照明装置技术领域本发明涉及透镜, 透镜包括第一表面和第二表面,其中第一表面包括:光入射表面,光从该入射表面进入透镜; 以及全反射表面,其中进入透镜的光的一部分被全反射,第二表面包括光出射表面,其中光入射表面包括分配给不同光源的多个三维表面,一部分 来自一个光源的光从分配给一个光源的一个三维表面进入透镜,另一个部分从未分配给一个光源的一个三维表面进入透镜。 镜头结构紧凑,可以均匀混色。
