In addition, due to the limitation of the electric power line installed in the cold cathode lamp tube via the inverter and the length of the cold cathode lamp itself, it is suitable for large and large products, but it was limited to make small products. In addition, since the cold cathode lamp tube itself is made of a thin glass tube, there is a risk of breakage, and workability and distribution were not limited.

According to the present invention, all three primary colors (Green-Green, Red-Red, Blue-Blue) are absorbed and diffused as a whole by absorbing the light emitting diodes (LEDs) of the three primary colors (three wavelengths) and the light emitted from the LEDs. By applying a light guide plate that reflects, various light colors are implemented according to the signal control to display the advertisement light emitting display to provide a light color changing billboard that can be added to the optimum advertising effect for the advertisement in addition to the sophisticated lighting effect The purpose is.

In order to achieve the above object, the light color changing billboard of the present invention has a plurality of three primary LEDs in which various primary colors are implemented by combining light of three primary colors and is mounted along the length direction, and a circuit board equipped with a power terminal at one end thereof. A light guide plate coated with a light shielding sheet that absorbs light from the three primary LEDs, diffuses and reflects the light entirely, and blocks light leakage at both ends thereof, and an inner side of the light guide plate to be detachably inserted into the light guide plate. A reflection plate formed with an advertisement insertion groove, and a substrate seating groove is recessed so that the center light guide plate and the reflector plates on both sides of the light guide plate are seated together with the silicon finish, and the tri-directional LED is operated on either side. The product consists of a light guide plate support with buttons installed.

In addition, the light guide plate support may be fixed to the ceiling installed through the cable bar, the power cable is disposed as a power means. And the power means is connected to the power terminal of the circuit board via a power cable is characterized in that it is applied to any one of the power supplied from itself by being replaced with a battery that is supplied from the outside or supplied with power.

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

1 to 3 illustrate a light color changing billboard in accordance with a basic embodiment of the present invention, and shows a combined state, a separated state, and a detailed front-facing structure. In addition, FIG. 4 is a view illustrating a use state in which the billboard is installed on the ceiling 50 through the cable bar 42 according to the embodiment of the present invention.

As shown in the drawing, the present invention is a combination of various colors by the light emission of the three primary color LED 62, and the advertisements (34a, 34b) of both sides through the light guide plate 20 is displayed by the illumination light of various colors The product consists of a billboard that is implemented to be able to be.

First, three primary colors LED 62 are formed on the circuit board 60 along the longitudinal direction so that three primary colors (green-red, red-red, blue-blue) can be emitted and various light colors can be realized by the combination. Mounted, it is preferable that the operation button 14 is installed on one side of the lower light guide plate support (10a) that is normally located as a switch means for applying power to these three primary color LED 62 to operate.

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 LEDs 62 of the circuit board 60 can be absorbed without being diffused in all directions and diffused and reflected as a whole. 20 is preferably finished by applying a light shielding sheet 22 to block the light leakage at both ends. This means that the light of the three primary LEDs 62 is transmitted and diffused to the light guide plate 20, so that the light leaks in both directions in the longitudinal direction so that the advertisements 34a and 34b of both sides can be uniformly and brightly emitted. Make it possible to shade the masonry.

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 62 so that the light is diffusely reflected and reflected. The light guide plate 20 itself is configured to emit light significantly higher and more evenly than the light emitting ability of the light emitting device 62, and that the light guide plate 20 itself may emit light for a predetermined time even when the three primary LEDs 62, which are light emitting means, are turned off. It can be configured to have together.

The reflective plates 30a and 30b made of a transparent acrylic material are configured like the light guide plate 20 so that the advertisements 34a and 34b can be detachably inserted at both sides of the light guide plate 20. Advertisement inserting grooves (32a) and (b) are formed in the reflection plates (30a) and (30b), respectively, so that the advertisements (34a) and (34b), which are usually coated with vinyl, can be easily inserted and fixed. At this time, the vertical height of the light guide plate 20 is formed to be relatively longer than the vertical height of the light guide plate 20 in the center, which is the three primary LEDs 62 mounted on the circuit board 60 below the light guide plate 20 and the external exposure. Consider the mounting height of the power supply terminal 64.

In addition, the circuit board 60 and the light guide plate 20 in the center and the reflecting plates 30a and 30b on both sides of the light guide plate 20 are seated on the upper and lower sides of these components, respectively. Light guide plate support (10a) (10b) is recessed (12b) is installed and coupled. That is, end portions of these components are inserted and seated between the substrate seating grooves 12a and 12b of the light guide plate supports 10a and 10b serving as upper and lower frames of the present invention, and the gap is usually finished by silicon. It can be structured integrally and stably as a whole.

On the other hand, the light guide plate support 10a, 10b, which is basically configured to be separated up and down, may be applied only as the other light guide plate support without configuring one light guide plate support 10a or 10b as necessary. At this time, the circuit board 60 is fixed to the power supply terminal 62 is seated in one of the light guide plate support substrate mounting groove (12a or 12b) of course applied. The light guide plate support position of the position to be omitted may be finished as a normal plate-like body.
