The present invention relates to a bus billboard that changes color to maximize passenger convenience according to identification and commerciality according to various advertisements.

In general, the acrylic billboard is attached to a vehicle such as a bus is mainly applied, the situation is introduced a variety of billboards to which the light emitting means is applied to induce the customer's view more actively. This is because the billboards that emit light are continuously favored because of the advantage that the advertisement effect of the advertisement can be maintained even in the dark environment such as nighttime or rainy weather after sunset as well as during the day.

However, the luminous billboards introduced so far have merely revealed the advertising phrases of the advertisements, so there was a limit that the contents of advertisements could not be actively delivered to customers. In particular, in the case of buses, the usual acrylic billboards are applied to the windows and frames of vehicles, and the advertising effect is inevitably weak.

Of course, by applying a billboard that emits a solid color to the frame of the vehicle, the convenience of providing a bus number to passengers is more easily provided, but a bus-only billboard that can deliver active advertising effects to customers for the purpose of commercial advertising is It is not yet introduced.

The present invention was developed in view of the above situation, and the outside route number surface and the commercial advertisement surface of the vehicle interior are centered on a middle light guide plate that can diffuse light with low power in various colors by circuit control. The combination of three primary colors (RCB) LED light can be changed to emit light of various colors, so that the passengers can easily check the bus number outside the bus, as well as various public service advertisements for the passengers inside the bus. The purpose of the present invention is to provide a bus billboard that changes color that can maximize the commerciality that can be actively delivered commercial.

In order to achieve the above object, the light color changing bus billboard of the present invention is mounted on a circuit board at regular intervals and is controlled by three primary color LEDs that realize various light colors according to a combination of three primary colors, and the three primary LEDs. A light guide plate that absorbs light and diffuses and reflects the light as a whole, a transparent reflector coupled to form a predetermined gap on both sides of the light guide plate, and is inserted between two transparent reflector plates and a central light guide plate, thereby displaying a commercial advertisement surface inside the bus. On the outside of the bus, the advertisement () expressing the bus route surface, the middle light guide plate and the transparent reflector plates on both sides form the main frame so that the components do not come off, and the supporting side plates on both sides are screwed to the window frame of the bus. The product is configured to include a light guide plate support frame.

In addition, the light guide plate support frame is formed with an advertisement insertion groove formed on the upper side to draw out the advertisement, the material is characterized in that any one of aluminum or synthetic resin (acrylic) that is easy to mold.

Hereinafter, with reference to the accompanying drawings a preferred embodiment for the configuration and operation of the light-changing bus billboard according to the present invention will be described in detail.

Figure 1 shows the overall structure of the bus billboard according to the present invention, in the circle centered on the three primary color LED 30, which is a light emitting means that the light is changed to a variety of colors in accordance with the control signal of the circuit board 32 The main structure of the bus billboard in which the advertisements 24a and 24b are inserted between the light guide tube 20 and the transparent reflecting plates 22a and 22b on both sides and between the light guide plate 20 and the transparent reflecting plates 22a and 22b 2 shows a state in which the light guide plate support frame 10 forming the main frame of the bus billboard according to the present invention is integrally structured by screwing the glass window frame 40 of the bus.

As is well known, a light emitting diode (LED) is a display element that converts an electric signal into a light signal as a semiconductor that emits light when a direct current flows, and a light emitting plate using the LED as a display means or a light emitting means. (In some cases, advertising board) displays the corresponding letters, figures, etc. by illuminating the LED-controlled light emitting pattern on a circuit board by arranging LED modules on a circuit board at a predetermined interval or at a predetermined color.

In particular, the three primary LEDs 30, which are applied to the bus advertisement board of the present invention and are mounted on the circuit board 32 at regular intervals, emit light of three primary colors (green-green, red-red, and blue-blue). Various light colors can be realized, and the operating power source uses the DC power source of the bus.

In addition, the light guide plate 20 is installed above the circuit board 60 so that the light emitted from the plurality of three primary color LEDs 30 of the circuit board 32 can be absorbed without being diffused in all directions and diffused and reflected as a whole. 20) is finished with a light guide plate support frame 10 which is integrally coupled to the glass window frame 40 of the bus while acting as a light shielding sheet to block the leakage of light at both ends. This is because the light of the three primary color LED 30 is transmitted and diffused to the light guide plate 20 so that the light leaks in both directions in the longitudinal direction so as to emit light uniformly and brightly on both advertisements 24a and 24b. Can be shaded.

In particular, the light guide plate 20 applied to the present invention is a form in which the copper tube pattern of the phosphorescent paint is printed as a whole, and absorbs the light emitted from the three primary LEDs 30 and diffuses and reflects the light as a whole. It is configured to emit light significantly and evenly than the light emitting capacity of 30, and the light guide plate and the photoluminescent function that the light guide plate 20 itself can be emitted for a predetermined time even when the three primary LEDs 30, which are light emitting means, are turned off. There is also an additional photoluminescent effect that can be provided together.

In addition, transparent reflector plates 22a and 22b made of a transparent acrylic material are configured similarly to the light guide plate 20 so that the advertisements 34a and 34b can be detachably inserted with respect to both sides of the light guide plate 20. The transparent reflector plates 22a and 22b may be formed with recesses for inserting advertisements, respectively, so that the advertisements 24a and 24b, which are usually coated with vinyl, can be easily inserted and fixed. It is preferable that the advertisement insertion grooves 32a and 32b are formed on the upper side of the light guide plate support frame 10 as a structural feature coupled to the glass window frame 40. In particular, it is preferable that the transparent reflector plates 22a and 22b maintain a thickness of about 0.04-0.05mm so that the advertisements 24a and 24b, which are actual outputs, can be more accurately transmitted and observed.

In addition, the light guide plate support frame 10 which forms the main frame of the bus billboard of the present invention has advertisement insertion grooves 34a and 34b formed thereon to draw out advertisements 22a and 22b. The material may be variously applied as long as the material is easy to be molded while having aluminum or synthetic resin (acrylic) or other constant durability. In particular, in order for the light guide plate support frame 10 to be easily and stably integrated into the glass window frame 40 of the bus, a screw fastening hole 14 is formed through the support side plate 12 of the light guide plate support frame 10 and is usually screwed. Can be fixed integrally to the window frame 40 by a combination.

In addition, the advertisements 24a and 24b positioned on both sides of the advertisement insertion grooves 34a and 34b formed on the upper side of the light guide plate support frame 10 forming the bus advertisement plate of the present invention are intermediate light guide plates ( 10) The advertisement 24a on the surface of the bus route is printed on the outside of the bus, and the advertisement on the commercial advertisement surface such as various commercial advertisements and public service advertisements. 24b is located.
