Description

TECHNICAL FIELD [0001] The present invention relates to a multi-stage light emitting diode (LED) light guide plate,

The present invention relates to a multi-stage light emitting advertising bulletin board incorporating an LED light guide plate, and more particularly, it relates to a multi-stage light advertising bulletin board incorporating an LED light guide plate, The present invention relates to a multistage luminescent advertising post which incorporates an LED light guide plate which is convenient for maintenance and reduces energy consumption and can clearly display advertisement contents in a dark place or at night.

Advertising is an intimate medium that can meet people anywhere in the world, whether on the ground or underground, and at the same time, it has a function as an information delivery medium that can not be ignored. That is, the advertisement enhances the reminder effect on the product or the company, thereby enhancing the purchase effect on the product. Various types of advertising means are used for such advertisements. Of these advertising means, the banner is widely used because it can be seen to have many effects at a low cost.

The banner is installed in a place where a large number of people are floating and an unspecified number can be easily identified, for example, around a building such as a roadside or an apartment complex, and a cloth fabric and a sheep cloth And a string connected to the upper and lower sides of the brace. However, since the banners constituted as above are produced in different sizes and installed in various parts of the city in a disorderly manner, they cause serious harm to the beauty of the city. Therefore, in the urban areas, the use of the banners is limited in recent years.

In order to solve the above problems, most municipalities have produced and used a multi-stage banner post which can post multiple banners on a frame member fixed on the ground. However, in the case of replacing the placard, the multi-story placard has a disadvantage that the worker has to work on the placard to tie or loosen the placard to the frame member.

In addition, the conventional multi-stage banner banner simply displays a plurality of banners, and the advertisement contents are not properly displayed in a dark place or at night so that the readability is remarkably lowered. Therefore, the advertising effect for the purpose of the banner is not generated, There was a problem of falling into a wreck facility.

In order to solve the above problem, there has been an attempt to provide advertisement lighting effect in a dark place or at night by installing a light for illuminating a banner. However, when the external light is transmitted through the back of the banner, it is difficult to maximize the lighting effect of the light due to the nature of the material of the banner made of cloth.

In addition, when the external illumination is illuminated from the front of the banner, the light of the external illumination is scattered on the banner surface, so that the contents of the banner can not be easily identified to the public. In addition, incandescent lamps and fluorescent lamps, which are generally used as external lights, have a problem in that they are incompatible with current government energy policies because they consume a large amount of energy.

On the other hand, there are electronic banners utilizing LCDs or PDPs as advertising means that can induce advertisement effects in the dark or at night. The electronic banner is configured by arranging a plurality of LCDs or PDPs in the horizontal direction, or by vertically arranging the same as in the case of a typical multi-stage banner placard, and by displaying information such as an advertisement image so that an unspecified number can be visually recognized And

However, the electronic banner has a problem in that it can not properly manage the delivery, replacement, and maintenance of the advertisement. In order to overcome such a problem, a remote controllable electronic banner is disclosed in Korean Patent Laid-Open No. 2005-0117486.

The remotely controllable electronic banner has a plurality of electronic banners and one remote electronic control unit connected to each other via a wired / wireless communication network to freely change the advertisement contents of the electronic banner to improve the management efficiency. However, in the case of the above-mentioned remotely controllable electronic banners, the configuration is complicated and the initial installation cost is high, for example, the electronic control unit and the wired / wireless communication network must be installed, and maintenance of each equipment is difficult.
