[0026] The present invention will be further explained below in conjunction with the accompanying drawings.

[0027] like Figures 1 to 4 As shown, a compound eye lens structure 9 of the utility model includes a plurality of sub-areas 1, each of which includes a shading array 2 and a lens array 3, the shading array 2 is arranged before or after the lens array 3 along the light propagation direction, and the distance between the shading array 2 and the lens vertex in the lens array 3 is ≤1mm. A substrate 4 for carrying the shading array 2 and the lens array 3 is also included. The shading array 2 and the lens array 3 are arranged on the same side or two opposite sides of the substrate 4.

[0028] like Figure 2 As shown, the shading array 2 and the lens array 3 are arranged on the surface of the substrate 4 facing the light source; Figure 3 As shown, the shading array 2 and the lens array 3 are arranged on the surface of the substrate 4 away from the light source; Figure 4 As shown, the shading array is arranged on the surface of the substrate 4 facing the light source, and the lens array 3 is arranged on the surface of the substrate 4 away from the light source.

[0029] The lens array 3 is composed of a plurality of lenses 5. The lenses 5 in the same sub-region 1 have the same curvature radius and the lens vertices are arranged in the same plane. The lenses in different sub-regions 1 have different curvature radiuses and the lens vertices are arranged in the same plane or the lens bases are arranged in the same plane.

[0030] The light shielding array 2 includes a plurality of light transmission patterns, which correspond to the lenses in the lens array one by one, and each light transmission pattern is different, so that different parts of the light passing through the lens in the corresponding lens array 3 are blocked, and all unblocked light is superimposed again behind the compound eye structure to form a back field with a specific distribution. The back field is the light field located behind the compound eye lens structure along the propagation direction of the light.

[0031] In the utility model, through artificial intelligence fast calculation, the shading patterns are infinitely exhausted, and each light-transmitting pattern that meets the back-stage lighting requirements is searched out.

[0032] like Figures 5 to 8 As shown, for the lens array, the lenses 5 constituting the lens array are in the shape of a circle, a square or a regular hexagon, and adjacent lenses 5 in the same sub-area are in close contact with each other. By making the lenses 5 in close contact with each other, light loss can be effectively avoided.

[0033] like Fig. 9 As shown, a lighting lamp of the present invention comprises a light source array 6 and the above-mentioned fly-eye lens structure 9, and the light emitted by the light source array 6 passes through the fly-eye lens structure 9 to form an illumination field thereafter. The light source array 6 comprises at least one LED 10.

[0034] With the lighting lamp of the utility model, when one LED of the light source array 6 is lit, the light passes through a sub-area to form an 8° small light cone lighting field, achieving a "spot lighting" effect; when another LED is lit, the light passes through another sub-area to form a 40° large light cone lighting field, achieving a "flood lighting" effect; when the above two LEDs are lit at the same time, a "mixed lighting" effect is achieved.

[0035] like Fig.10 As shown, a lighting lamp of the utility model comprises a light source array 6, the above-mentioned compound eye lens structure 9, and a collimator lens array 7 arranged between the light source array 6 and the compound eye lens structure, wherein the light emitted by the light source array is collimated by the collimator lens array 7 and then passes through the compound eye structure. The collimator lens array 7 comprises at least one optical curved surface.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
