Abstract:
1. An illumination beam shaping system having total quantity of light form a light excitation chip enabled to undergo a pre-dividing operation, and then post-diffusion to cause an optical illuminating surface of the system to obtain uniform illumination brightness, comprising: a light-emitting element, wherein the light-emitting element is a light, excitation chip for producing a light beam with angular illumination; a dividing device, which is structured from a planar assembly of a plurality of curved lens provided with curvature arranged in an array, and an assembly of incident light surfaces of the plurality of curved lenses form an input side of the dividing device, while the other side forms an output side assembled from emergent faces of the plurality of curved lenses; the input side faces the light beam projection surface of the light-emitting element; an optical diffusing component, provided with an incident plane of curved form with a concave curvature, wherein the incident plane faces the output side of the dividing device, and is positioned at bottom portions, which function as actual optical surfaces, of the conical light beams emitted from the output side, wherein each of the curved lenses assembled to form the dividing device has a different curvature.
