Description

Advertisement display system

The present invention relates to an advertisement display device using a light emitting diode (LED), and more particularly, to an advertisement display device mounted on a traffic light for pedestrians or vehicles.

Recently, in the advertising panel used for advertising, propaganda or news transmission, according to the development of LED technology, advertising to use the LED mounted on the ceiling of the building, signboards, etc. to attract people's attention is gradually increasing.

The display device of an electronic signboard using such LEDs is disclosed in Korean Utility Model Publication No. 20-0195633 and Korean Utility Model Publication No. 20-0205892.

In addition, the technology for producing an advertisement effect by applying the above-described LED to traffic signals and the like is disclosed in Korean Patent Laid-Open No. 1999-0046712 and Korean Utility Model Publication No. 1999-33535.

Since the technology disclosed in the above publication has only a very simple function of the existing traffic lights, it only has a function of notifying whether or not the pedestrians are walking, so it is possible to determine how long pedestrians wait for a signal change and whether the traffic lights are broken or not. Not only that, but also to solve the problem that pedestrians feel bored and free while waiting for signals.

That is, as shown in FIG. 1, the current pedestrian traffic light is to be converted into the pedestrian traffic light shown in FIG.

In Fig. 1, reference numeral 1 denotes a mounting lamp for a traffic light, numeral 2 denotes a red display panel, and numeral 3 denotes a blue display panel.

As a result, practical mounting has many problems for satisfying the above-described relationship.

In addition, in the above publication, the advertisement is performed by the same color as the color of the traffic light, but no specific technique for realizing this is disclosed. For example, when the blue traffic light indicating the progress of the vehicle is turned on, the advertising effect is Not only was there a problem that caused traffic accidents.

In addition, in the traffic lights currently being used, the conversion from the red traffic light, which is the stop signal, to the blue traffic light, which is a traffic signal, is suddenly converted without notice, thereby causing an accident of collision with a pedestrian or a vehicle that is about to depart quickly.

An object of the present invention is to solve the problems of the prior art as described above, to provide an advertisement display device synchronized with the red or blue flashing signal of the existing pedestrian traffic lights.

Another object of the present invention is to provide an advertisement display device synchronized with a blinking signal of red, yellow, or blue of an existing vehicle traffic light.

Still another object of the present invention is to provide an advertisement display device which can be installed more safely and simply while using an existing pedestrian traffic light or traffic signal traffic light as it is.
