[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown, a multifunctional LED display screen for an ETC toll lane of an expressway comprises a bracket 1 provided with a display screen 2, a light bar 4 provided with lamp beads 40, and a light-transmitting cover 5 rotatably provided on the bracket 1;

[0023] The light-transmitting cover 5 is provided with light-transmitting holes 51 arranged at equal intervals. The light-transmitting cover 5 in the rotating state synchronously drives the light bar 4 to rotate, and the lighting angle of the lamp beads 40 is adjustable.

[0024] Specifically, the bracket 1 is installed on the road sign frame using bolts and nuts, and the road sign frame stands on both sides of the highway. The display screen 2 and the bracket 1 are both existing technologies and will not be described in detail here.

[0025] Furthermore, the lamp beads 40 use spotlights of different colors, and the lamp beads 40 of the display screen 2 can display the same color. The electrical connection method is the existing technology and will not be described here. The light bar 4 is columnar and movable on the bracket 1, and the light-transmitting cover 5 is a corrosion-resistant stainless steel metal cover.

[0026] Furthermore, an arc-shaped shield 3 is fixedly mounted on the bracket 1, so that the shield 3 can shield and protect the light bar 4 and the light-transmitting cover 5, reduce the damage to the lamp beads 40 caused by rain, and ensure the working safety of electronic components.

[0027] By using the light bar 4 in the default state, the lamp beads 40 are directed downward, and at this time the light shield 5 does not block the lamp beads 40, and the color displayed by the lamp beads 40 is the same as the lane reminder color on the display screen 2, making it easier for the vehicle to judge lane changes based on the color of the light irradiated on the ground lane. In rainy and foggy days, the light shield 5 is rotated to block the lamp beads 40, and the light holes 51 are illuminated by the lamp beads 40. At the same time, the light bar 4 rotates synchronously, so that the illumination angle of the lamp beads 40 is tilted toward the direction of the vehicle, so that the colored light beam can inform the oncoming vehicle in advance, making it convenient for the driver to change lanes in advance. In combination with the equidistantly arranged light holes 51, the light is segmented to avoid the light irradiating the vehicle all the time and affecting driving safety. The Tyndall effect is then used to make the tilted light beam more obvious for the driver to identify and judge.

[0028] As an embodiment further provided by the present invention, symmetrically arranged triggering members 52 are fixedly mounted on the light-transmitting cover 5 , and a contacted member 43 abutted by the triggering member 52 is provided on the light bar 4 .

[0029] Specifically, the triggering member 52 and the contacted member 43 are both arc-shaped hard metal sheets, and the two are in a buckled state.

[0030] By rotating the light-transmitting cover 5, the triggering member 52 is moved to be embedded in the touched member 43, so that the touched member 43 is hooked and pulled by the triggering member 52 and rotates synchronously, which is used to rotate the light strip 4 around the shaft on the bracket 1, so as to facilitate the change of the illumination angle of the lamp bead 40. The purpose is to move the light-transmitting hole 51 to the light inclined position in advance so that the light can be diverged.

[0031] As another embodiment further provided by the present invention, a reflective layer 50 is provided on the inner circle of the light-transmitting cover 5 , and a lampshade 41 matching with the reflective layer 50 is fixedly mounted on the light bar 4 .

[0032] Specifically, the lampshade 41 is arranged outside the lamp bead 40, and the transparent lampshade 41 is made of common materials on the market, and the reflective layer 50 is a reflective paint applied on the inner side wall of the transparent cover 5. The lampshade 41 and the paint are both existing technologies and will not be described here.

[0033] By using the lamp beads 40 in the default state, part of the light is irradiated on the reflective layer 50 of the light-transmitting cover 5, so that this part of the light is diffused through the arc-shaped reflective layer 50, so that bright light appears inside the bracket 1 at this position, so that the road sign frame can form color differentiation in the default state, thereby improving the driving judgment effect.

[0034] As another embodiment further provided by the present invention, the light bar 4 is provided with a reflective surface 42 that matches the reflective layer 50 .

[0035] Specifically, the reflective surface 42 is provided on the housing of the light bar 4, and the reflective surface 42 and the reflective layer 50 are made of reflective paint, and the paint is corrosion-resistant and high-temperature-resistant, and the prior art is not described in detail here; Figure 3 As shown, the solid arrow represents the rotation direction of the light-transmitting cover 5 in foggy and rainy days, and the dotted arrow represents the direction of light irradiation.

[0036] The light bar 4 is driven to rotate to the end position. At this time, the light from the lamp beads 40 will illuminate the inner wall of the light-transmitting cover 5 where no light-transmitting holes 51 are set, and the light will be reflected onto the reflective surface 42, thereby forming a reflection method similar to that of an optical cable, and then emitted from the port of the light-transmitting cover 5, so that the light is emitted toward the sky, further enhancing the long-distance judgment of the vehicle.

[0037] As another embodiment further provided by the present invention, a rack 53 is provided on the outer ring of the light-transmitting cover 5 , and a driving tooth 54 meshing with the rack 53 for transmission is provided on the bracket 1 .

[0038] Specifically, the driving gear 54 is driven by a motor, and the electrical connection between the motor, the display screen 2 and the lamp beads 40 is a conventional technology and will not be described in detail here.

[0039] The driving teeth 54 engage the transmission rack 53 to drive the light shield 5 to rotate on the bracket 1, so as to facilitate the position adjustment of the light hole 51 of the light shield 5 and also facilitate the adjustment of the lighting angle of the light bar 4.

[0040] Working principle: The light bar 4 in the default state makes the lamp beads 40 shine vertically downward, and the light shield 5 does not block the lamp beads 40 at this time, and the color displayed by the lamp beads 40 is the same as the lane reminder color on the display screen 2, making it easier for vehicles to judge lane changes based on the light color irradiated on the ground lane. On rainy and foggy days, the light shield 5 is rotated to block the lamp beads 40, and the light holes 51 are illuminated by the lamp beads 40. At the same time, the light bar 4 rotates synchronously, so that the illumination angle of the lamp beads 40 is tilted toward the direction of the vehicle. The light beam can inform oncoming vehicles in advance, making it convenient for the driver to change lanes in advance, and cooperate with the equally spaced light holes 51 to make the light be segmented, and then cooperate with the Tyndall effect to make the inclined light beam more obvious, so that the driver can identify and judge, and the light bar 4 is driven to rotate to the end position. At this time, the light of the lamp bead 40 will illuminate the inner wall of the light-transmitting cover 5 where the light-transmitting holes 51 are not set, and the light will be reflected on the reflective surface 42, thereby forming a reflection method similar to that of an optical cable, and then emitted from the port of the light-transmitting cover 5, so that the light is emitted towards the sky, further enhancing the long-distance judgment of the vehicle.

[0041] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
