Technical Field

[0001] The invention relates to the technical field of signboards, in particular to an LED tourist signboard for tourist attractions. Background Art

[0002] In tourist attractions, it is crucial to provide tourists with accurate and clear road guidance information. Traditional tourist signs mostly use static text or patterns for instructions, which has limitations in information update and diversified display. With the continuous development of LED technology, LED tourist signs have gradually become an indispensable part of tourist attractions.

[0003] Existing LED tourist signs are usually composed of components such as base plates, hanging parts, signboards and LED light groups. The hanging parts are used to fix the signboards on walls or poles, the signboards are used to display road guidance information, and the LED light groups are used to illuminate the signboards to improve the readability of the information. However, these signs still have some shortcomings in design and function.

[0004] First, the signboards of traditional LED tourist signs are usually fixed and cannot be replaced, which makes the information update inflexible and unable to meet the changing needs of tourist attractions. Secondly, some signboards are difficult to clean and maintain because cleaning staff need to manually wipe the screen and signboard, which is not only inefficient but may also cause damage to the screen and signboard. In addition, the existing signboards are relatively simple in the way they display information and lack diversified display methods.

[0005] In order to solve the above problems, a new type of LED tourist sign is needed, which should have the functions of replaceable identification plate, easy cleaning and maintenance, and diversified information display. Summary of the invention
