Description

Technical Field

[0001] The utility model relates to an upper cover plate for a fish tank and a fish tank adopting the upper cover plate. Background Art

[0002] In the prior art, the upper cover of the fish tank is usually a simple plate body, which is mainly used to cover the opening of the fish tank to prevent fish from jumping out or foreign debris from entering, and can also reduce water evaporation and maintain the stability of water quality in the fish tank. These upper covers are usually made of materials such as plastic, glass or metal, with simple appearance and single function.

[0003] However, in traditional designs, the top cover often does not take into account the issue of lighting. Since fish need proper lighting to maintain their biological clock and nutrient metabolism, fish tanks usually require additional light sources to provide lighting. Traditional top covers often do not have integrated lighting functions, and users need to purchase or install lighting equipment separately, which increases the complexity and cost of use.

[0004] Therefore, in the prior art, although the upper cover plate can complete the basic functions, the demand for lighting is not well met. The lack of integrated lighting function causes users to invest extra time and money to select and install appropriate lighting equipment. Utility Model Content
