A lighting system for providing uniform bright lighting of products within in a glass door refrigerated cabinet. The lighting system has a frame member with an angled wing extending therefrom that wraps around a side edge of a light-transmitting optical shield, and a LED lighting strip positioned between the frame member and the optical shield. The LED lighting strip has a plurality of spaced-apart LED lights mounted therealong with a coined reflective facet optic mounted around each LED light. The angled wing(s) reflects light emitted laterally outwards from the at least one LED lighting strip such that the light can be re-directed to evenly illuminate products in a refrigerated cabinet. The angled wing(s) also protects a user's fingers from cracking the plastic optical shield which can become brittle in the cool or cold temperatures of the refrigerated cabinet.

A photocatalytic structure that can uniformize ultraviolet lights is provided. The photocatalytic structure includes a housing, a groove formed at a top of the housing, multiple grille slices being engaged with two sides of an inner wall of the groove, multiple grille passages being formed between every two adjacent grille slices, metal meshes disposed on both top and bottom of the grille slices, and a UVC-LED light board disposed at a side of the grille slices. The photocatalytic structure stacks the grille slices to form the grille passages. The UVC-LED light board makes grille passages to reflect the ultraviolet light. More uniform lights are formed at both upper and lower sides of the grille passages. The UVC-LED light board close to the metal meshes ensures the uniform lights to be emitted onto a gap plane with a smaller refraction angle. Therefore, everywhere on the metal meshes are fully illuminated.
