The bus number plate is for informing bus passengers of the desired bus number. Conventional bus plates are attached to the front glass of the bus or to the side of the bus as shown in FIG. To behave disorderly. In particular, due to the implementation of the central bus lanes in Seoul, buses line up at bus stops on their way to and from work. In addition, the conventional bus license plate has a short line of sight at night or in bad weather, making it difficult for bus passengers to identify the bus number. That is, the conventional bus license plate has a factor that the bus passengers can not easily recognize the bus number, which causes traffic congestion and disorder as well as traffic accidents.

The light reflected by the bus number identification unit 1 is concentrated in the reflection room 2 composed of white reflectors, and the reflected light is again concentrated in the bus number display unit 10. The reflection room 2 may be configured in various shapes as necessary, but it is preferable that the reflection room 2 is configured in a hemispherical shape so that the emitted light and the reflected light can be concentrated on the bus number display unit 10.

The bus number identification unit 1 is configured to be detachably attached to the protection frame, and can replace only the bus number identification unit 1 when the bus number is to be changed.

An LED 4 is provided at the top of the reflection room 2 composed of a hemispherical shape or the like. The LED is coupled to the LED installation hole (3). The LED 4 can be variously discolored according to the bus color. In detail, if the bus is blue, the LED is also selected to emit blue light. If the bus is red, the LED is also selected to emit red light.

At least one LED 4 is configured according to the number of bus number display units. When the bus number display unit 1 is disposed on the front, rear, left and right sides of the bus, the LED 4 is also disposed on at least one of the front, rear, left and right sides.
