In particular, the light source 3 may be an LED lamp. The secondary light dispersing structure 5 can be a single lens or a lens group.

In some alternative embodiments of the present invention, as shown in fig. 2 and 4, the lens assembly has a plurality of microlens units 51, and the radius of curvature of each of the lens units 51 is the same. Therefore, the light emitted by the light source can be more uniformly scattered by the lens group. More specifically, the plurality of microlens units 51 are arranged in an array to further uniform the scattering of the light emitted from the light source by the lens group.

In the following, a practical embodiment is used to illustrate the arrangement of the lens group. The microlens units 51 are arranged in an array with the central axis of the light emitted from the light source 3 as the symmetry axis, that is, the number of the microlens units at the central axis of the light emitted from the light source 3 is 1, and then the number of the microlens units 51 surrounding the microlens units is arranged with the number of equal differences with the tolerance of 6 (the tolerance can be any integer, and the embodiment with the tolerance of 6 in the description in this paragraph is only an exemplary illustration for explaining the claims).

Therefore, the light passing through the secondary light scattering structure 5 can be uniformly refracted, and the light emitted from the secondary light scattering structure 5 can be uniformly distributed. For example, when the light distribution angle of the light source 3 is 20 °, the image-side aperture angle of each microlens is sin20 °, and the radius of curvature of the microlens is 0.1936438532216357 mm.
