PURPOSE: A rotatable air inflating LED advertisement display apparatus is provided to display various advertising copies according to the needs of a user using an LED having good visibility and facilitate to carry and move by easily installing and separating an air tube without occupying too much space. CONSTITUTION: An air tube(4) is formed with a transparent material, an advertising copy is printed or coated with a fluorescent material or a light reflective material on an internal surface or on an external surface, and the advertising copy is illuminated by receiving light projected from an LED of an LED module. A connecting unit(4a) is formed at the lower part of the air tube, a coupling protrusion(4b) is formed by protruding to an outer direction at the lower part of the connecting unit, and the coupling protrusion is coupled by being inserted into an insertion groove(25a) of a middle connecting member(25). A rotator(3) consists of an air inflating module(10), a rotation module(20), an LED module(30), a control module(40) and a support stand(50), and the LED module projecting light to the air tube is mounted. The air inflating module inflates the air tube with air by connecting to the air tube and including multiple driving motors(11), multiple air pumps(12) and a nipple(13). The rotation module consists of a rotary driving motor(21), a pulley(22), a connecting pipe(24) and the middle connecting member and rotates the air tube by connecting to the air tube. |
