[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.
[0003] Active luminous signs are a new type of traffic sign. Using LED light sources and retroreflective materials, they emit light actively in all weather conditions, improving the readability of the sign information. Compared to traditional passive reflective signs, active luminous signs offer greater visibility distance and better visibility in adverse weather conditions, significantly improving traffic safety and driving efficiency. Using active luminous traffic signs to improve visibility in various weather conditions, creating a safer and more orderly traffic environment, and replacing ordinary passive reflective traffic signs has become a traffic management trend.
[0004] Most current active luminous signs are implemented by embedding LED strips or light bars inside, with a light-transmitting plate in front of the light and a light-shielding plate behind. However, the use of LED lights always involves maintenance issues. Some signs require disassembly from the front, while others require large-scale disassembly from the back, making maintenance inconvenient, costly, and even damaging to the sign. Utility Model Content
[0005] The purpose of this invention is to provide an easy-to-maintain active luminous sign, simplifying the installation and disassembly of long light strips, avoiding damage to the light-transmitting plate in front of the light strips, and effectively saving installation and maintenance costs.

[0016] The frame profile is provided with a sliding groove, and the upper and lower ends of the baffle can slide in the sliding groove to expose or cover the opening.
[0017] Furthermore, the light strip is elongated.
[0018] Furthermore, two adjacent light strips are connected by a shorting wire.
[0019] Furthermore, the opening position of the upper plate is specifically: an opening is made on the upper plate corresponding to the connection point of adjacent light strips.
[0020] Furthermore, the opening size on the upper plate is smaller than that on the lower plate.
[0021] Furthermore, the upper and lower plates are arranged in parallel.
[0022] Furthermore, the lamp trough is a dovetail groove shape that is narrow on the outside and wide on the inside.
[0023] Furthermore, the bottom of the light trough can hold the light strip.
[0024] Furthermore, the light trough is elongated.
[0025] Furthermore, a light-shielding plate is provided on the non-light-emitting portion of the front of the frame profile.
[0026] The technical solution of this utility model has the following beneficial effects:
[0027] This utility model provides an opening on the back of the frame profile around the illuminated sign. A baffle on the back of the frame profile can slide on the frame profile to expose or cover the opening. This eliminates the need for extensive disassembly during maintenance. By combining light strips and light troughs, the installation and disassembly of long light strips are simplified, avoiding damage to the light-transmitting plate in front of the light strip and effectively saving installation and maintenance costs.

[0038] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
[0039] It should be noted that the terminology used herein is for the purpose of describing particular implementations only and is not intended to limit the exemplary implementations according to this utility model.
[0040] Where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.
[0041] This utility model discloses an easy-to-maintain active luminous sign; such as Figure 1-7As shown, an easy-to-maintain active luminous sign includes: a frame profile 5, a light-transmitting plate 2, and a baffle 6. The frame profile 5 is the four-sided frame profile of the sign, and is an integrated structure that provides both the external frame of the sign and allows for the internal embedding of LED lights. The frame profile 5 is an existing structure, with cavities at the top and bottom. These cavities are designed to ensure the thickness of the active luminous sign and the width of the light-emitting strips. Diffuse reflection is only achieved when the light strips are placed inside and a certain distance is maintained between them and the light-transmitting plate; otherwise, the LED beads will be visible from the outside, affecting the viewing experience. The frame profile 5 determines the dimensions of the active luminous sign, including the width of the luminous portion and the width of the non-luminous portion.
[0042] like Figure 1 As shown, the upper frame profile 5 on the same side as the baffle is also provided with a mounting groove 5f, which can be fixed to the column on site with the help of sliding bolts. The mounting groove 5f and the sliding bolts are also existing technologies, and will not be described in detail here.
[0043] like Figure 7 As shown, the light-transmitting plate 2 is located at the front end of the frame profile 5, and the non-light-emitting part at the front is equipped with a light-shielding plate 1 to achieve illumination around the sign. The baffle 6 is located at the rear of the frame profile 5.
[0044] like Figure 2 As shown, the frame profile 5 has an upper plate 5a and a lower plate 5b inside. The upper plate 5a and the lower plate 5b are parallel to each other and parallel to the installed baffle 6. The light strip 4 is installed on the upper plate 5a. The light strip 4 is deformable. There is a light groove 3 between the light strip 4 and the upper plate 5a. The light strip 4 is long and narrow. The light groove 3 is a transparent plastic strip with a dovetail shape, which is narrow on the outside and wide on the inside. It is also long and narrow. The width of the light strip 4 is close to the bottom inner dimension of the light groove 3. The bottom of the light groove 3 holds the light strip 4 in place, so that the light strip 4 does not loosen. Moreover, the light strip 4 can be pulled out of the light groove 3 with force.
[0045] The light trough 3 is glued to the upper plate 5a with adhesive on the back. The width of the upper plate 5a depends on the width of the light-emitting frame. Based on the width, two layers of light troughs 3 and light strips 4 can be added. The light-transmitting plate 2 is fixed to the front end of the frame profile 5 by adhesive.
[0046] like Figure 4 and Figure 5 As shown, the light strip 4 is a series of long strips. Adjacent light strips 4 are connected by shorting wires 7. In order to facilitate maintenance and replacement, an opening needs to be made on the frame profile 5 at the connection point of the two light strips 4. The baffle 6 is removed, and the light strip 4 can be installed and replaced through the opening.
[0047] The baffle 6 is located behind the frame profile 5, and a sliding groove 5e is provided at the rear of the frame profile 5. The upper and lower edges of the baffle 6 slide within the sliding groove 5e of the frame profile 5, respectively. The baffle 6 acts like a sliding door, normally protecting the openings on the frame profile 5 from wind and rain. During maintenance, it is pushed aside to expose the openings on the frame profile 5, avoiding extensive disassembly and improving maintenance efficiency. The sliding function of the baffle 6 is simple and easy to understand, and will not be elaborated here.
[0048] like Figure 3 and Figure 4 As shown, the specific opening method on the frame profile 5 is to open a small opening 5c on the upper plate 5a and a large opening 5d on the lower plate 5b, forming a notch that is larger on the outside and smaller on the inside when viewed from the back.
[0049] The working principle of this utility model is as follows:
[0050] like Figure 6 As shown, during maintenance, push the baffle 6 to one side to expose the notch, disconnect the jumper wire 7, bend the light strip 4 outwards to deform it elastically, and simultaneously pull it outwards against the clamping force of the dovetail groove bottom of the light trough 3, passing through the small opening 5c and the large opening 5d in sequence, finally completely detaching it from the light trough 3 and pulling it out from the notch. During installation, pass the light strip through the large opening 5d and the small opening 5c in sequence, bending it elastically and inserting it into the light trough 3 from the notch. The dovetail groove bottom of the light trough 3 automatically clamps the light strip 4 to prevent it from coming out. Insert the entire light strip completely, assembling it in place, and then connect it to the adjacent light strip 4 using the jumper wire 7. Similarly, connect the other end of the light strip to the adjacent light strip using the same method. Finally, pull the baffle 6 back to block the notch in the frame profile 5, completing the maintenance and replacement.
[0051] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
