Description

Technical Field

[0001] The utility model belongs to the technical field of traffic warning equipment, in particular to a luminous traffic sign. Background Art

[0002] LED luminous traffic signs are graphic symbols that display traffic regulations and road information. They can express traffic regulations in a vivid, specific and concise manner. They are used to manage traffic and indicate driving directions to ensure smooth roads and safe driving. They are suitable for highways, urban roads and all special highways, and both vehicles and pedestrians must abide by them.

[0003] The existing LED luminous traffic signs include a metal panel, a large installation opening is opened on the metal panel, a transparent plastic panel is embedded in the installation opening, a plurality of through holes are opened on the plastic panel, and the plurality of through holes form warning patterns. Then a layer of inner reflective film is pasted on the plastic panel, and then a layer of outer reflective film of other colors is pasted on the metal panel. A hollow hole is opened on the outer reflective film at a position corresponding to the warning pattern. An LED backlight assembly is arranged on the back of the metal panel. When the LED backlight assembly is lit, light passes through the through holes and hits the area of ​​the inner reflective film corresponding to the warning pattern, so that the warning pattern is partially lit.

[0004] The above-mentioned existing LED light-emitting traffic signs have the following defects: first, the structure of installing the transparent plastic panel in the installation port is relatively complicated; second, when the LED backlight assembly is lit, since the light has to pass through the plastic panel to hit the inner reflective film, the light loses part of its brightness in the process of passing through the plastic panel. Therefore, if the warning pattern wants to reach the desired brightness, a higher-power LED backlight assembly needs to be set up so that the light is strong enough to make the warning pattern reach the required brightness, resulting in high energy consumption of the LED light-emitting traffic signs; in addition, in actual usage scenarios, the size of some LED light-emitting traffic signs is very large, and thus a larger plastic panel is required, and the plastic panels are all injection molded. Due to the production process limitations of the plastic panels, when the size is large to a certain extent, the plastic panel cannot be injection molded, which limits the production and manufacturing of large-size LED light-emitting traffic signs. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems in the existing technology and propose a luminous traffic sign. The technical problem to be solved by the utility model is: how to solve the problem that the existing luminous traffic signs have high power consumption and are inconvenient to produce.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A luminous traffic sign comprises a metal panel and a back panel, characterized in that a frame is arranged at the outer edge of the metal panel, the back panel is buckled on the frame and fixedly connected to the frame; an LED backlight assembly and a battery pack for powering the LED backlight assembly are arranged on the back panel, a warning pattern formed by a plurality of through holes is provided on the metal panel, an inner reflective film covering the warning pattern is provided on the outer surface of the metal panel, an outer reflective film is provided on the outer surface of the inner reflective film, a light-transmitting hole is provided on the outer reflective film at a position corresponding to the warning pattern, the shape of the light-transmitting hole is the same as the shape of the warning pattern, and the color of the inner reflective film is different from the color of the outer reflective film.

[0008] Working principle: The LED backlight assembly and the battery pack are both enclosed inside. The battery pack supplies power to the LED backlight assembly. After the LED backlight assembly is lit, the light passes through the through hole and directly hits the inner reflective film, making the warning pattern light up. The setting of the outer reflective film is to shield the other parts of the inner reflective film except the warning pattern, so that only the warning pattern on the inner reflective film is lit. When the vehicle shines on the outer reflective film, the driver can see the light reflected by the outer reflective film, which attracts the driver's visual attention and makes the entire luminous traffic sign more eye-catching and easy to observe. The present structure eliminates the setting of the plastic panel and adopts a through hole directly opened on the metal panel. The warning pattern is composed of a number of through holes, which makes the processing and manufacturing of the luminous traffic sign more convenient; secondly, the light directly passes through the through holes and hits the inner reflective film, and the light is basically lossless. A brighter warning pattern can be produced using a lower-power LED backlight component, which significantly reduces the power consumption of the entire luminous traffic sign and increases the power supply time of the battery pack to the LED backlight component; in addition, the metal panel can be cut into any size, which is convenient for the manufacture of luminous traffic signs of various sizes.

[0009] In the above-mentioned luminous traffic sign, the through hole is a regular hexagonal hole. With the arrangement of this structure, when the inner reflective film blocks the through hole, the regular hexagonal hole facilitates light penetration while making it difficult for the naked eye to observe the shape of the hole.

[0010] In the above-mentioned luminous traffic sign, the LED backlight assembly includes an LED light bar, which is fixed on the inner surface of the back plate and corresponds to the area of ​​the warning pattern. Through the arrangement of this structure, the LED light bar has a plurality of LED patches, and when the LED patches are lit, the light passes through all the through holes and is aligned with the area of ​​the warning pattern.

[0011] In the above-mentioned luminous traffic sign, a solar panel is installed on the outer wall of the frame, a control circuit board is arranged on the inner surface of the back plate, the control circuit board is electrically connected to the LED backlight assembly and the battery pack, a wire 1 electrically connected to the solar panel is arranged in the frame, the end of the wire 1 is connected to a male plug, a wire 2 is connected to the control circuit board, the end of the wire 2 is connected to a female plug, and the male plug is plugged with the female plug. Through the arrangement of this structure, the arrangement of the solar panel is convenient for charging the battery pack, and the arrangement of the male plug and the female plug is convenient for connecting the solar panel with the control circuit board.

[0012] In the above-mentioned luminous traffic sign, the control circuit board has a power button for controlling the traffic warning screen, and the back plate is provided with a clearance hole, and the end of the power button extends outward through the clearance hole. Through the arrangement of this structure, the arrangement of the power button facilitates the opening or closing of the luminous traffic sign.

[0013] In the above-mentioned luminous traffic sign, a mounting seat is fixed on the outer surface of the back plate.

[0014] In the above-mentioned luminous traffic sign, the mounting seat is an aluminum profile, and the mounting seat is riveted to the back plate. Through the arrangement of this structure, the connection between the mounting seat and the back plate is stable and convenient.

[0015] In the above-mentioned luminous traffic sign, the outer end of the frame is bent inward to form a flange, the back plate is buckled on the flange, the back plate and the flange are connected by fasteners, and a sealing gasket is arranged between the inner surface of the back plate and the flange. Through the arrangement of this structure, the sealing gasket seals the connection between the back plate and the flange, and dust or water from the outside is not easy to enter the interior of the luminous traffic sign.

[0016] In the above-mentioned luminous traffic sign, the inner reflective film is a white reflective film, and the outer reflective film is a red reflective film.

[0017] In the above-mentioned luminous traffic sign, the metal panel, frame and back plate are all made of aluminum or aluminum alloy.

[0018] Compared with the prior art, the utility model has the following advantages: the structure eliminates the setting of the plastic panel and adopts a through hole directly opened on the metal panel. The warning pattern is composed of a number of through holes, which makes the processing and manufacturing of the luminous traffic sign more convenient; secondly, the light directly passes through the through hole and hits the inner reflective film, and the light is basically lossless. A brighter warning pattern can be produced using a lower-power LED backlight component, which significantly reduces the power consumption of the entire luminous traffic sign and increases the power supply time of the battery pack to the LED backlight component; in addition, the metal panel can be cut into any size, which is convenient for manufacturing luminous traffic signs of various sizes.
