[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0032] In the description of the embodiments of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0033] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.
[0034] Combination Figure 1-6 As shown, a traffic guidance sign includes: an outer frame 1 with openings on the front and rear sides, a display panel 2 with traffic guidance signs, and a rear cover plate 3; the traffic guidance signs on the display panel 2 are made of a semi-transparent retroreflective material; the display panel 2 is fixedly connected to the outer frame 1 and covers the front opening of the outer frame 1, and the rear cover plate 3 is fixedly connected to the outer frame 1 and covers the rear opening of the outer frame 1; the display panel 2, the outer frame 1, and the rear cover plate 3 together enclose an installation space 4; an LED light group 5 is provided in the installation space 4, and the LED light group 5 can emit light sources toward the display panel 2.
[0035] For example, the outer frame 1 is a waterproof metal frame; the traffic guidance sign on the display panel 2 is made of a semi-transparent retroreflective material, which makes the information content of the display panel 2 have high contrast and clear display, ensuring that the retroreflective performance meets the specifications. When the traffic guidance sign is in a backlit state, sunlight or other external light shines on the display panel 2 from the rear through the rear cover plate 3 and the LED light group 5; at night or when there is no obvious external light source, the LED light group 5 is turned on and emits light towards the display panel 2, so that the driver can clearly distinguish the content of the traffic guidance sign.
[0036] In some embodiments, the rear cover 3 is a solar panel, which is electrically connected to the LED light assembly 5. The solar panel absorbs and stores solar energy during the day, and can supply power to the LED light assembly 5 at night or when there is insufficient external light, so that the LED light assembly 5 can operate without being connected to an external power source.
[0037] In some embodiments, the solar panel is a light-transmitting solar panel. Exemplarily, the light-transmitting solar panel is a high-transmittance solar fiber panel with a dustproof and waterproof fluorine coating on its surface. This helps ensure that sunlight passes through the light-transmitting solar panel and reaches the display panel 2 even in backlit conditions, facilitating the absorption and storage of sunlight.
[0038] In some embodiments, the traffic guidance sign also includes a light-sensitive control component 6, which is mounted on the rear cover plate 3 and electrically connected to the LED light group 5. Exemplarily, the light-sensitive control component 6 is an intelligent light-sensitive control component 6, which can be integrated into the rear cover plate 3 to detect sunlight environment data and automatically adjust the switching and brightness of the LED light group 5 according to environmental changes such as dimness, rain, and fog. The intelligent light-sensitive control component 6 can also be linked with smart streetlights and other intelligent devices to intelligently adjust the light-emitting strategy of the LED light group 5 based on environmental monitoring data.
[0039] In some embodiments, the LED light group 5 includes a plurality of LED light sheets 51, which are rotatably connected to the outer frame 1. As each of the LED light sheets 51 rotates, the LED light group 5 can switch between a light-passing position and a light-blocking position. When the LED light group 5 is in the light-passing position, a light-passing channel 52 is defined between the plurality of LED light sheets 51. When the LED light group 5 is in the light-blocking position, the plurality of LED light sheets 51 are connected, and the emitting end of the LED light sheet 51 is aligned with the rear side of the display panel 2.
[0040] For example, LED light group 5 uses a light source with strong penetrating power, resulting in a long visibility distance and meeting the needs of use in harsh weather conditions. When backlit, LED light group 5 rotates to the over-light position, such as... Figure 3 , Figure 4As shown, the light assembly is currently in the open position. Sunlight passes through the rear cover 3, through the light channel 52, and illuminates the display panel 2. The LED light assembly 5 uses a low-energy, high-efficiency light source with a light decay rate of ≤8%. At night, the LED light assembly 5 is rotated to the light-blocking position, as shown... Figure 5 , Figure 6 As shown, the light group is currently in the closed state, and the LED light sheet 51 illuminates the rear side of the display panel 2. The LED light group 5 can be connected to other intelligent devices such as the intelligent light-sensing control component 6 to automatically adjust the brightness of the LED light sheet 51 according to the ambient brightness. It supports controls such as flashing, constant light, and off. The open state of the light group is the closed state of the LED light sheet 51, and the closed state of the light group is the constant light state of the LED light sheet 51. Switching the light group back and forth between the open and closed states can make the LED light sheet 51 flash.
[0041] In some embodiments, multiple LED light sheets 51 are arranged in parallel. When the LED light group 5 is in the light-passing position, a light-passing channel 52 is defined between any two adjacent LED light sheets 51. When the LED light group 5 is in the light-blocking position, multiple LED light sheets 51 are connected in sequence. In backlighting conditions, this allows most of the sunlight passing through the rear cover plate 3 to pass through the light-passing channel 52 and illuminate the display panel 2. In dim weather conditions such as at night or during rain or fog, the sequential connection of multiple LED light sheets 51 can block sunlight from the rear cover plate 3, allowing only the LED light group 5 to illuminate the display panel 2, ensuring clear display of directional content.
[0042] In some embodiments, a homogeneous light guide plate 7 is also provided within the installation space 4. The homogeneous light guide plate 7 is located on the front side of the LED light group 5 and is fixedly connected to the outer frame 1. Exemplarily, the homogeneous light guide plate 7 adopts a unique optical refraction design, which makes the panel display shadow-free and the brightness uniform, ensuring that the light source on the back of the guide sign is evenly projected onto the front of the guide sign.
[0043] In some embodiments, the traffic guidance sign also includes a terminal for electrical connection to an external power source, the terminal being electrically connected to the LED light group 5. For example, the LED light group 5 can be integrated with the power system of a smart city, such as smart streetlights, to better achieve intelligent control of the LED light group 5.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
