    • The present invention relates to lens (1), for an illuminating device, comprising a base (2) and a microlens array arranged on the base (2), wherein the microlens array comprises a plurality of microlenses (3), respective microlens (3) has a light incident surface (4) facing a light source (S) of the illuminating device and a light emergent surface (5) facing away from the light source (S), wherein the light incident surface (4) is a first curved surface (4) that defines a cavity (R) opening to the light source (S), and the light emergent surface (5) is a second curved surface (5) configured in a such a manner that light (L) incident through the first curved surface (4) emerges in a uniform diffuse transmission manner. Light emerging from the lens can be diffused on an object to be illuminated and realize an expected light distribution effect. In addition, the present invention further relates to an illuminating device with the lens.
    • 本发明涉及一种用于照明装置的透镜(1),包括基底(2)和布置在基底(2)上的微透镜阵列,其中微透镜阵列包括多个微透镜(3),各自的微透镜(3) )具有面向照明装置的光源(S)的光入射面(4)和背离光源(S)的光出射面(5),其中,光入射面(4)为第一弯曲 限定通向光源(S)的空腔(R)的表面(4),并且光出射表面(5)是第二弯曲表面(5),其被配置成使得通过 第一曲面(4)以均匀的漫射方式出现。 从透镜出射的光可以扩散到待照射的物体上,并实现预期的光分布效应。 另外,本发明还涉及具有透镜的照明装置。
