Description

Luminous road traffic sign

Technical Field

The invention mainly relates to the field of road traffic sign manufacturing, in particular to a luminous road traffic sign.

Background

With the development of road traffic, the beautification of roads and the improvement of traffic safety requirements, the application of road traffic luminous signs is more and more. These luminous road traffic sign both can play the effect that daytime is normally instructed or night reflection of light instructs, and when the light source board was luminous night at the same time, the marking panel also can the printing opacity make the positive effect that plays the luminous instruction.

In the prior art, the luminous road traffic sign includes a full-transparent array type luminous sign, a semi-transparent array type luminous sign, and a dot array type luminous sign. The full-transparent array type luminous sign is characterized in that a sign panel is made of a full-transparent material, a lamp panel is arranged between a back plate and the sign panel (namely, a transparent panel), a reflective film with traffic indication pictures and texts is arranged on the front surface of the sign panel (namely, the transparent panel), and when the lamp panel is lightened, the whole transparent panel can be lightened. The translucent surface array type luminous sign is characterized in that the sign panel is made of opaque materials (namely, a translucent panel), the front face of the translucent panel is provided with a reflective film with traffic indication pictures and texts, hollow parts are arranged at positions corresponding to the traffic indication pictures and texts on the translucent panel (light-transmitting plates are embedded at the hollow parts), and therefore when a lamp panel between the back plate and the translucent panel is lightened, the translucent surface array type luminous sign can only lighten the traffic indication pictures and texts through the hollow parts to form a translucent lightening effect. The dot-matrix luminous sign is characterized in that the sign panel is made of opaque materials, the front face of the opaque panel is provided with a reflective film with traffic indication pictures and texts, and then the luminous lamp beads are correspondingly arranged according to the traffic indication pictures and texts and are directly fixed on the opaque panel.

In the prior art, some of the above-mentioned luminous road traffic signs have the following technical problems:

first, in order to light the sign, a battery module is provided inside the sign (i.e., between the back plate and the sign panel), and the battery module is connected to an external solar panel. However, the charging and discharging of the battery assembly have a certain service life (generally 2-3 years at present), and the traffic sign is firm in structure and installation and is erected on the sign post at a certain height, so that the battery assembly in the sign needs to be replaced every 2-3 years, the whole sign needs to be detached at high altitude every time, and then the whole backboard is opened for replacement. The method not only ensures that the maintenance operation time is long, the maintenance workload is large, certain operation safety hidden dangers exist, but also easily damages the signboard in the dismounting and remounting processes, and seriously increases the operation cost. And in order to make the battery that is in sign inside can not take place to rock and then cause the damage to inside lamp plate etc. when transportation or installation, generally all can be when the installation with the very firm fixing of battery inside the sign through a plurality of mountings, the operation degree of difficulty when this kind of fixed mode has also increased follow-up change has increased activity time cost and human cost.

Secondly, the aesthetic property is an important measurement point of the traffic sign without safety. Since it is well known that road signs are numerous as part of urban public facilities, it is desirable to simplify and beautify traffic signs as much as possible so that they do not cause damage to the urban aesthetic and urban appearance environment. And a separate battery box is arranged outside the sign and is arranged below the sign through a sign rod or directly protrudes on a back plate of the sign, so that the battery can be replaced without detaching the whole sign. However, the structure is obviously too bulky and not aesthetic, and the aesthetic feeling of the city is indirectly destroyed.

And thirdly, an independent solar panel is arranged above the marking rod of one mark, and the solar panel is electrically connected with the battery in the mark below or the battery box through an electric wire. This further results in a bulky structure and impairs urban aesthetics. Secondly, the marker post needs to reserve two installation positions for solar panel and traffic sign at least (some need to reserve an installation position for the battery case more), also need to install respectively during the installation for the installation is loaded down with trivial details, and the work load is big. And thirdly, the independent and separated solar panel and the traffic sign need to be connected through wires, so that the connection part is easily affected by wind, wind and sunlight to cause the problems of short circuit and the like, and the maintenance is not changed. Fourthly, the independent solar panel is easy to collide with and damage in the transportation and installation construction process, and the operation cost is seriously increased.

Fourth, the existing light signs are generally powered by a single battery. When the battery is in a rainy day for a long time or the battery is just up to the service life but is not replaced soon, the battery use-up mark cannot emit light, which can cause serious influence on the road safety. Such unlit or dimly lit road signs can be particularly problematic when special conditions are encountered (e.g., a fog just in place and a large number of vehicles are present, or a sign is required to remain on for a certain period of time during a special day).
