A lens is disclosed. The lens includes: a plurality of light incident surfaces respectively covering a plurality of light emitting diode chips disposed on a substrate and receiving light emitted from the plurality of light emitting diode chips; a plurality of light exit surfaces configured to output the light from the lens; a lower surface extending from an edge of each of the plurality of light incident surfaces toward an edge of each of the plurality of light exit surfaces; and a flange connecting the plurality of light exit surfaces to the lower surface of the lens. Each of the plurality of light incident surfaces includes a first central axis, and each of the plurality of light exit surfaces includes a second central axis. The first central axis and the second central axis are located at different positions above each of the plurality of light emitting diode chips. 公开了一种透镜。所述透镜包括：多个光入射面，分别覆盖设置在基底上的多个发光二极管芯片并接收从所述多个发光二极管芯片发射的光；多个光出射面，被构造为从所述透镜输出所述光；下表面，从所述多个光入射面中的每个的边缘朝向所述多个光出射面中的每个的边缘延伸；以及凸缘，将所述多个光出射面连接至所
