This utility model discloses an aquarium lighting lamp, including a UV lamp assembly and an external assembly. The UV lamp assembly includes a lampshade, with a spiral flow channel installed on the inner side wall of the lampshade, a lamp tube base installed on the inner bottom wall of the lampshade, and a UV lamp body installed on the inner side wall of the lamp tube base. Through the spiral flow channel, the water enters from the top inlet pipe and, instead of flowing directly and quickly through the lampshade, is forced to flow downwards along a spiral path. This significantly prolongs the residence time of the water within the effective irradiation area of ​​the UV lamp body, thereby significantly improving the killing efficiency against various bacteria, viruses, and algal spores, achieving deep and efficient sterilization. Furthermore, the UV lamp body is completely sealed inside the lampshade, preventing ultraviolet rays from directly irradiating the aquarium water, thus completely avoiding potential damage to the eyes, skin, and cell tissues of fish.
