Description

Rotary Type Signborad Using Residual Image

The present invention relates to an advertisement device, and more particularly, to a rotating advertisement device that can display a specific phrase or pattern by using the afterimage effect of the LED installed to blink in a rotating body rotating at a high speed by the drive module. will be.

In general, the advertising device using the LED mainly uses a display board in which the LED is arranged vertically and horizontally.

The LED signboard has a problem that the manufacturing cost is expensive because a large number of LEDs must be installed vertically and horizontally, and the conventional LED signboard is manufactured in the form of a panel of a predetermined standard, and only advertisements such as letters and pictures are directed toward the front of the LED. Although the content can be expressed, it does not display any advertisement content on the back or side, and because it is opaque, when the LED signboard is installed on the glass wall fixed to the entrance side of the store, the inside of the shop is viewed through the LED signboard. Therefore, the problem that the display and display effect of the goods located on the back side of the LED sign is reduced.

Recently, a plurality of LEDs are arranged in a row on one or more of the plurality of rotary vanes attached to a rotating body rotated by a small motor, and then the LEDs are turned on by selectively blinking the plurality of LEDs. LED rotating display device to display a variety of characters and pictures by using the afterimage effect of was introduced in the Utility Model Registration No. 0257301.

However, since the rotating advertisement device including the conventional LED rotation display device as described above, the rotating wing is made of a flat plate or a straight line, the advertising text is not well seen from the side, and there is a flaw that is different depending on the angle of the viewer.

In addition, the conventional rotary advertisement device has a structure in which the terminals for continuously supplying the external power to the LED mounted on the rotating body elastically contact, but if the elasticity of the terminal deteriorates during long-term use, the contact between the terminals is not well made. There may be a problem that the LED does not blink normally, and there is a problem that friction noise may occur due to the contact between the terminals.

Registered Utility Model No. 0257301 (registered Dec. 2001) Registered Patent No.1314152 (registered Sep. 26, 2013) Publication No. 2005-0033361 (published Apr. 2005) Registered Patent No. 1517194 (registered April 27, 2015)
