In general, the light emitting means using the light emitting diodes is widely used in various fields such as various billboards, traffic lights, vacant car indicators such as taxis, and the like. A plurality of light emitting diodes are formed on the entire front surface of a printed circuit board having a predetermined plate shape. The light emitting diodes were lightly arranged to be regularly arranged and connected to circuits, and each LED was turned on through a conventional control unit to display various characters or figures. However, in the case of such light emitting means, a large number of light emitting diodes are attached to a printed circuit board in a dense state. Due to the high power consumption, it is expensive to manufacture and maintain, and due to the high temperature generated in a large number of light emitting diodes, the lifespan of the light emitting diodes is shortened, so there are frequent problems. In addition, dot emitting is performed in the state where each light emitting diode is concentrated. To represent a particular figure or character When the light emitting means is applied to a traffic light, the light emitted from the plurality of light emitting diodes is directly radiated to the driver, causing glare, which may cause traffic accidents, and to prevent such glare.
