Description

{ADVERTISEMENT SIGN WITH LED LIGHTINGS}

[0001] The present invention relates to an advertising sign that can be used as a road traffic sign, and more particularly, to an advertising sign that can be used as a road traffic sign or the like. More specifically, By attaching detachably, it is possible to easily replace the LED lighting means and billboard at the time of maintenance and to prevent deformation of the square frame even in a large structure having a width larger than the vertical height, and realize a high brightness with low power consumption, And also to an advertisement sign using an LED that maximizes an advertisement effect.

Generally, an advertising sign using lighting means is a type of advertising means for allowing a specific consumer or a trader to make a quick and memorized stay in a specific consumer product or a company for a long time in a memory, And is realized in various shapes and shapes according to

The conventional advertising sign is a method of irradiating light from the back side of the light guide plate using CCFL, EEFL or the like as a light source in the state that the advertisement sheet is provided on the front side of the light guide plate. However, in the case of such CCFL and EEFL lighting means, the AS is not easy and the light source replacement is not easy when the life of the light source is short.

Further, in the prior art, since the rear surface (back surface) irradiation method for irradiating light from the back surface of the light guide plate is used, in order to irradiate the light to the entire area of the light guide plate, a large number of light sources must be mounted in proportion to the area, There was a problem.

Furthermore, even if the light is emitted through the light guide plate, the illuminance of the light emitted to the front face through the entire light guide plate is low, so that the advertising plate provided on the front face of the light guide plate is not exposed brightly and clearly.

Accordingly, the inventor of the present invention can irradiate the entire light guide plate using only a relatively small number of LED lights through a "advertisement panel implementing a light-sensitive advertisement part" of Korean Patent No. 10-1026881, The entire size of the advertisement panel can be largely reduced to secure an easy installation space and to increase the distance aesthetics when mounted, and the advertisement text itself can be colored or emitted by the light emitted from the surface, As a result, we have successfully developed an advertising panel that can be installed in a small space at a low cost and maximize the advertising effect.
