The present invention relates to a lighting decorative plate having a light emission diffusion function that can be uniformly diffused illumination of the light emitting plate of the LED light emitting body as a whole without the use of a light guide plate, and more specifically, a plurality of installed at a predetermined interval on one side of the decorative plate body. As the LED light emitting body illuminating the decorative decoration advertisement (advertisement or decoration) is illuminated evenly without structural blackening phenomenon, the light source is reflected and diffused through the reflection diffuser on one side and the curved surface reflector on one side without expensive light guide plate. The present invention relates to a lighting decorative plate having a light-emitting diffusion function that can greatly improve the lighting ability of the LED light emitting body and improve the decorative performance and the advertising performance by lighting.

As is well known, a common billboard having a light emitting means to illuminate the advertisement includes a conventional incandescent lamp or a fluorescent lamp as well as a cold cathode fluorescent lamp (CCFL) on one side of a frame that forms the form of the billboard. It is equipped with various light emitting means such as a light emitting diode (LED), and reflecting plates (finishing plates) are arranged on both sides of the front of the light emitting means together with advertisements, so that the light source of the light emitting means To reach and illuminate.

Of course, various methods have been applied to allow the light source of the light emitting means to be more effectively reached and illuminated by the advertisement. However, when the size of the billboard is large, the light source of the light emitting means does not reach evenly until the end of the advertisement. The limit that the effect is exposed is exposed, and the light emitting means can be increased in order to increase the lighting efficiency, but this requires a high power consumption, which poses a problem in stability.

On the other hand, as a billboard or decorative plate using an LED light emitting device as a light source (light source), the latest technology introduced to provide a sophisticated lighting effect with the optimum advertisement (decoration) effect on the advertisement (decoration) As shown in FIG. 1, a light guide plate 150 is installed on a light emitting circuit board 142, which is a printed circuit board (PCB), at a predetermined interval, and the light guide plate 150 is installed at the center of the light guide plate 150. The transparent reflector plate 120 is coupled to one or both sides, and the decorative advertisement 130 is inserted between the light guide plate 150 and the transparent reflector plate 120, so that the light source of the LED light emitting unit 140 is used to guide the light guide plate 150.
