Battery unit 11 for storing the power generated by the charging module 30, the communication module 16 for performing wireless communication with the external control server 17, the LED module 14 and the second light emitting module ( The controller 13, which controls the overall operation of the 15, and supplies power stored in the battery unit 11 to the LED module 14, the second light emitting module 50, the communication module 16, and the controller 13. The power control part 12 which controls a power supply is provided.

The LED module 14 is a means for emitting light using a light emitting diode. In the present invention, since one of the main features is that various colors can be displayed to the outside, it is preferable that the LED module is a package module capable of displaying multiple colors. The specific configuration of such an LED module may use a known technology and is not directly related to the present invention, and thus detailed description thereof will be omitted. As described below, the LED module 14 determines the color to be operated and expressed by a control signal for whether the operation is received from the external control server 17 through the communication module 16 and whether or not the color is to be expressed. For example, when a control signal for expressing green is received from the external control server 17, the controller 13 controls the LED module 14 to emit green light based on the control signal.

Since the second light emitting module 50 is disposed along the outer surface of the housing 10 as described above, it is preferable to use an EL which is a surface light source. The second light emitting module 50 is preferably white or yellow so as to have excellent visibility without fatigue of the driver's eyes. The second light emitting module 50 may be omitted. In addition, the second light emitting module 50 is controlled in the same manner as the LED module 14 by the control signal from the external control server 17 to control the operation of light or not. When the second light emitting module 50 is controlled in combination with the LED light emitting module 14, a larger number of color combinations can be expressed, and thus, the second light emitting module 50 can function as a sign according to a road situation. For example, as shown in FIG. 3, the control signal may be determined to operate the LED module 14 and the second light emitting module 50, thereby enabling active expression of road conditions.

Since the solar charging module 30 and the battery unit 11 are as described with reference to FIG. 1, detailed descriptions thereof will be omitted. The power generated therefrom is supplied by the power control unit 12 to components requiring power such as the communication module 16, the LED module 14, the second light emitting module 50, and the like. The power control unit 12 is controlled by the controller 13. In FIG. 2, the power control unit 12 is independently shown as a separate component, but it is preferable that the power control unit 12 be integrated with the controller 13.

The communication module 16 receives a control signal by an external control server 17 and a wireless communication means and transmits the control signal to the controller 13. As described above, the controller 13 controls the overall operation of the LED module 14 and the second light emitting module 50 based on the control signal received from the communication module 16. The communication module 16 is preferably a ZigBee module, for example. Of course, other communication means such as wireless Internet, wireless LAN, Bluetooth, etc. may also be used, but it is preferable to use an address to transmit different control signals for each section and for each section. It is preferable to use a Zigbee module. For example, in the case of a highway, if an accident occurs near Giheung IC, the Seoul-Giheung section indicates that an accident has occurred and the road sign rod installed in the section to emit light in a certain color, for example, red, to indicate that the road is congested. Since the control signal can be transmitted based on the addresses of the Zigbee modules of all road marker rods installed in the road, the corresponding section can emit light in a specific color. Since the specific configuration of the communication module 16 also uses well-known technology, a direct description thereof will be omitted. However, the communication module 16 in the present invention can be applied to the present invention as long as it can transmit a desired control signal for each specific section by using a known wireless communication means. Of course, the communication module 16 is a configuration that can be omitted, and if the communication module 16 is omitted, the road sign 100 is the LED module 14 and the second as set in advance in the controller 13 The overall operation of the light emitting module 50 is controlled. In this case, changing the color or controlling the on / off operation would be somewhat cumbersome since it requires manual setting by the operator.

The controller 13 turns on / off the LED module 14 and the second light emitting module 50 by the control signal transmitted from the communication module 16 which has received the control signal from the external control server 17 as described above. Control signals for whether to turn off, the color to be expressed, etc. are transmitted to the LED module 14 and the second light emitting module 50. When there is no second light emitting module 50, only the LED module 14 may be controlled. In addition, as described above, when the configuration of the communication module 16 is omitted, the overall operation of the LED module 14 and / or the second light emitting module 50 may be controlled according to a preset rule. In addition, as described above, the controller 13 may be configured integrally by integrating the configuration of the power supply control unit 12.
