It can give visual traffic indication during the day; the indication is carried out by the irradiation and reflection of the coming vehicle at night. However, in the passive light reflecting mode, the light reflecting effect is limited, people cannot see the information of the sign in the place with poor light, the problem of uneven reflected light can be caused to the position for displaying the pictures and texts, and convenience can not be brought to passersby better. Accordingly, the prior art is deficient and needs improvement.

And the other is a composite light belt type traffic light-emitting signboard, and the local part adopts an LED display screen to indicate the road network. However, the LED display screen of the signboard is directly installed at the hollow-out position of the signboard, and although the LED display screen can display when the signboard is powered on, the LED display screen is equivalent to a blackboard once the signboard is in a power failure state. The traffic warning indicator can not be matched with other traffic indication pictures and texts on the signboard panel for indication in the daytime, and can not reflect light at night, so that the traffic warning indication function of the signboard is seriously influenced, and further, the traffic safety is also greatly influenced.

And thirdly, the lamp box type active luminous sign uses an LED light source inside, and the LED light source projects light to the back of the retro-reflection film through a back light source so as to light the luminous pictures and texts. However, the lamp box type active luminous sign has relatively large volume, complex assembly process, increased weight and great difficulty in manufacturing; the prior luminous signs can not locally change the layout content with low cost, so when the road network number and the like change, the whole luminous signs can only be removed and replaced; in addition, when the traditional non-luminous traffic sign board which is installed and used is upgraded and reformed into a luminous traffic sign, the original sign board can only be dismantled, and most of the dismantled parts can not be reused, thereby causing serious waste of resources.
