The present invention relates to a mirror type three-dimensional LED signboard using the reflection and penetration of light, which outputs information such as characters, images, and the like through an LED unit connected to a pixel panel in which a plurality of LEDs are mounted on a substrate in a matrix form. The LED signboard comprises: an LED unit including a plurality of LED pixel panels in which a plurality of LEDs are mounted on a panel substrate; a driving module for outputting a signal turning on/off LEDs (dots) of the LED pixel panels; a controller unit for controlling the LED signboard; a power unit for supplying power; and a signboard case on which the components are to be installed. The LED unit is configured to form a reflective surface on all the sides on which the LEDs are mounted, and further include a semi-transparent plate which is installed to be spaced apart from the reflective surface, and thus allows light, reflected by the semi-transparent plate, to be formed on the reflective surface, thereby: providing a depth effect or a three-dimensional effect when displaying information on the LED signboard; and relatively improving readability by allowing a plurality of light emitting points to be formed. In addition, the LED unit can: maintain the readability as the light emitting points are formed on the reflective surface in the case of extending a size of a display; provide a beautiful appearance through the semi-transparent substrate; improve the appearance by preventing LED elements of the LED signboard from being exposed as they are; and protect the LED elements from a pollution source such as dust or the like. |
