The technical solution of the present invention will be further described in detail with reference to the accompanying drawings and embodiments.

As shown in fig. 1, the traffic sign board with the lamp panel locally illuminated inside comprises a back plate 1, a frame 2, a paved lamp panel 3 and a front plate 4, wherein one side edge of the frame body of the frame 2 is fixedly connected with the back plate 1 in a welding mode, the back plate 1 and the front plate 4 are both made of aluminum plates, and the thickness of the back plate is 1-4 millimeters. The frame body opposite side edge of frame 2 is connected with positive board 4 welded fastening, and backplate 1 and positive board 4 and frame 2 three have constituted the traffic sign tablet of box shape. The frame 2 is made of aluminum alloy, the width of the frame is 3.5 cm to 11 cm according to requirements, the traffic sign board generally placed on the side of a highway is small, the width of the frame 2 can be 3.5 cm, and the width of the frame 2 in a large traffic sign board on a highway can be 11 cm.

Specifically, referring to fig. 2, the frame 2 includes a section bar 21 and a corner 22, the bending angle of the corner 22 is 60-135 degrees, the corner 22 of 60 is used to form a traffic sign box body with a triangular structure, the corner 22 of 90 is used to form a traffic sign box body with a rectangular structure, and the corner 22 of 135 is used to form a traffic sign box body with an octagonal structure. Referring to fig. 3, the two ends of the corner 22 are provided with the insertion pieces 221, the corner 22 is inserted into the profile 21 through the insertion pieces 221, and after the insertion, a screw is required to be drilled into the insertion pieces 221 from the edge of the profile 21 to connect and insert into the inner portion, so that the frame 2 formed by the profile 21 and the corner 22 is firmer. The corner 22 is used as a connecting member between the profiles 21 and is in sealed butt joint with the profiles 21, so that the frame 2 forms a whole.

The supporting ribs 23 are arranged inside the frame 2, the end parts of the supporting ribs 23 are welded and fixed with the frame 2, and the thickness of the supporting ribs 23 is the same as that of the back plate 1 or the front plate 4. Specifically, referring to fig. 4, the support rib 23 includes a front contact plate 231, a back contact plate 232 and a sliding groove 234, the front contact plate 231 is fixedly connected to the back contact plate 232 through a bracket, a lamp plate mounting groove 233 is disposed between the front contact plate 231 and the back contact plate 232 and used for the light spreading plate 3 to pass through the support rib 23, and a clamping groove 235 is disposed at a connection position of the back contact plate 232 and the sliding groove 234. The two clamping grooves 235 are used for inserting the back plate 1 inside, and two clamping grooves 235 are arranged on the support ribs 23 and are located on two sides of the connecting position of the back contact plate 232 and the sliding groove 234. The sliding grooves 234 of the supporting ribs 23 are used for being inserted into ribs on the inserted bar of an external traffic sign, and the ribs are arranged on the back of the existing traffic sign and used for reinforcing the traffic sign to firmly fix the traffic sign on the top of the inserted bar. The support ribs 23 can be horizontally connected with the inner side of the frame 2 as required, and can also be vertically connected with the inner side of the frame 2, and the parts needing light transmission, such as the parts sheltered by the support ribs 23, need to be cut appropriately to prevent the support ribs 23 from shading.

One side of the paving lamp plate 3 close to the front plate 4 is paved with a plurality of related LED lamp bead modules which are connected in series, specifically, the LED lamp bead modules on the paving lamp plate 3 are uniformly arranged, the distance between every two adjacent LED lamp bead modules is 8-15 cm, and although the distance is a little long, the brightness provided by the LED lamp is completely enough for the illumination of the traffic sign board. The LED lamp bead modules are of square structures, four LED lamps which are connected in series are arranged in each LED lamp bead module, and the LED lamp bead modules can be directly ordered and obtained from the lamp market. During implementation, the LED lamp bead modules arranged on the paving lamp panel 3 are correspondingly paved only near the character fonts or patterns of the traffic signs needing to emit light, mainly in order to show the character fonts, the patterns or the frame lines needing to emit light.

Spread lamp plate 3 and install in the inside of frame 2 and with backplate 1 and positive board 4 parallel arrangement, spread lamp plate 3 and generally bond on the inboard surface of backplate 1 or support on the inner wall of frame 2 with the periphery of spreading lamp plate 3 in the inside of frame 2 all can. The surface of the front plate 4 is hollowed and carved according to the related content of the traffic sign board, so as to highlight the related characters or patterns, and the hollowed and carved position is the position needing to emit light and transmit light. The light guide plate 41 is adhered to the outer surface of the front plate 4, and is used for displaying the related contents of the traffic sign board, and the related contents are presented on the front plate 4 and are convenient for pedestrians or vehicles to view when passing through. The thickness of the light guide plate 41 may be the same as that of the front plate 4, and the light guide plate 41 may be made of a PC material or an LPG material, which has a good light transmission effect in normal use.

The reflective film is adhered to the outer side of the light guide plate 41 and comprises a first reflective film 42 and a second reflective film 43, the first reflective film 42 is bonded with the outer surface of the light guide plate 41, the first reflective film 42 is of a transparent frame structure, the first reflective film 42 is bonded with the second reflective film 43, the surface of the second reflective film 43 is arranged in a hollow mode according to related contents of the traffic sign, the second reflective film 43 is carved with related patterns or characters of the traffic sign in a hollow mode, and when the traffic sign is implemented, the second reflective film 43 generally needs a blue bottom film or a green bottom film.

On the basis of the original retroreflective sign, the back plate 1, the front plate 4 and the frame 2 form a box-shaped traffic sign board. The surface of the front plate 4 is carved according to the related content fretwork of the traffic sign board for highlight the related characters or patterns, the position to be carved is the position which needs to emit light and transmit light, the reflective film is attached on the front plate 4 according to the information content of the layout, and the light source passing through the LED lamp bead module is uniformly distributed on the light guide plate 41 when the box body internal paving lamp plate 3 is electrified and lightened, so that the front information is displayed clearly.
