Technical Field
[0001] This invention relates to the field of traffic management technology, and more specifically, to a traffic signal light with a built-in light guiding mechanism. Background Technology
[0002] Temporary traffic lights typically refer to traffic lights installed on urban roads or at construction sites where temporary traffic control is needed. Their main function is to ensure the safe passage of pedestrians and vehicles, and to maintain traffic order.
[0003] Compared to conventional traffic lights, temporary traffic lights offer greater flexibility in their installation and removal, allowing for adjustments based on actual conditions. For instance, when conventional traffic lights malfunction, temporary lights can be installed to temporarily direct traffic. Alternatively, during road construction, temporary lights can be placed at the entrance to the construction area to restrict vehicle movement and prevent vehicles from accidentally entering. Similarly, temporary traffic lights can be deployed to regulate traffic flow during large events or road repairs.
[0004] Because temporary traffic lights are used for temporary traffic control, they need to be moved after traffic control ends. In other words, temporary traffic lights do not remain in a fixed position but frequently need to be moved. However, such frequent moves can easily lead to the following problems with temporary traffic lights: First, temporary traffic lights need to be manually moved onto the vehicle before and after transfer. During this process, they are inevitably subject to tilting, shaking, and collisions. Second, the temporary traffic lights are also subjected to vibrations while on the vehicle during the transfer. Under these circumstances, temporary traffic lights are prone to random malfunctions such as seal failure (causing internal water ingress) and electrical component detachment (including extreme cases such as redundant circuit failure), which can easily lead to a situation where one of the traffic lights fails to light up properly.
[0005] Although temporary traffic lights can currently be repaired on-site, we often find that during the process from when a temporary traffic light malfunctions to when repair parts are available, one side of the light may fail to illuminate properly, which can easily impede the passage of those personnel. Summary of the Invention
[0006] The purpose of this invention is to provide a traffic light with a built-in light guiding mechanism, which connects two oppositely arranged light bodies through the light guiding mechanism and guides the light through the connecting part, thereby solving the problem mentioned in the background art, namely, the problem that it is easy to affect the passage of corresponding personnel during the process of obtaining maintenance parts.
[0007] To achieve the above objectives, a traffic signal light with a built-in light guiding mechanism includes a base, a support rod disposed on the top of the base, and a light box disposed on the top of the support rod. A light body is disposed on the side of the light box, and a self-illuminating area and a supplementary lighting area are disposed inside the light body. It also includes a light guide mechanism, which has a light-collecting end and a light-guiding end. In the two lamp bodies that are arranged opposite to each other, the light-collecting end is set to the illumination area of one lamp body, and the light-guiding end is set to the supplementary lighting area of the other lamp body. The light guide end directs the light collected by the light-collecting end to the supplementary lighting area, enabling the corresponding lamp to be lit even when the power is off.
[0008] In the above technical solution, the light guide mechanism is positioned between two opposing lamp bodies. When one lamp body emits light, the light can be guided through the light guide mechanism onto the other lamp body. In this way, even if one lamp body malfunctions, the malfunctioning lamp body still contains light guided by the light guide mechanism, thus enabling the malfunctioning lamp body to emit light.
[0009] Based on this, the lamp body includes a rear shell, a lamp panel, and a transparent cover, with multiple lamp beads arranged on the side of the lamp panel facing the transparent cover.
[0010] Based on this, the light guiding mechanism also includes a light guide tube with one end located inside the light box and the other end penetrating through the side wall of the light box, and a light guide strip with one end located inside the light guide tube and the other end extending into the supplementary lighting area; the end of the light guide strip corresponding to the supplementary lighting area is the light guiding end; the end of the light guide tube penetrating through the light box is the light collecting end; and the inner wall of the light guide tube is provided with a reflective coating.
[0011] In this structure, the light guide tube is used to collect the light from one of the lamps, and the light guide strip is used to guide the collected light to the other lamp.
[0012] Furthermore, the light panel has a high-brightness area corresponding to the light-receiving end, and high-brightness LED beads are installed within this area. The brightness of these high-brightness LED beads is higher than that of regular LED beads. The high brightness of these high-brightness LED beads makes the guided light brighter, improving the efficiency of human observation.
[0013] In another technical solution, the support rod is rotatably connected to the base, and the base is equipped with a motor for driving the support rod to rotate at a preset angle, wherein the preset angle is 90 degrees.
[0014] In this technical solution, the lamp body changes direction after rotating 90 degrees, and the light guide mechanism illuminates the lamp body in the opposite direction. Therefore, traffic control in four directions can be achieved by controlling the lamp body to rotate 90 degrees.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the traffic light with the built-in light guiding mechanism, the light guiding mechanism can create a light guiding channel between two opposing lamp bodies, so that the light emitted by one lamp body can be guided by the light guiding mechanism to the other lamp body. Thus, when one lamp body cannot be lit normally, the light guiding mechanism can be used to enable the back cover to continue to emit light, realize temporary emergency command, and improve the traffic efficiency in the process of obtaining repair parts.
[0016] 2. In this traffic light with a built-in light guiding mechanism, when there are multiple damages to the light body, the motor drives the light body to rotate. By coordinating the rotation and the light guiding mechanism, traffic can be directed in multiple directions, thereby further improving the command efficiency in emergency scenarios.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," 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 this invention 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 this invention.
[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.
[0022] Because temporary traffic light malfunctions are affected by various factors (collisions and vibrations during the transfer process), the location of the malfunction is random, making targeted prevention difficult. This means maintenance personnel can only obtain repair parts after a malfunction has occurred.
[0023] To address the issue that obtaining repair parts can easily obstruct the passage of personnel, this invention provides a traffic light with a built-in light guiding mechanism. For example... Figure 1 As shown, the traffic light is a temporary signal light. Therefore, the traffic light includes a base 100 with wheels, a support rod 101 connected to the top of the base 100, and a light box 102 fixedly connected to the top of the support rod 101. The light box 102 is a hollow cubic structure, and each side of the light box 102 is provided with a lamp body 110, and the working state of two opposite lamp bodies 110 is the same. In this way, placing the traffic light of the present invention in the middle of a crossroads can serve as a temporary traffic control function.
[0024] Specifically, such as Figure 2As shown, a water-retaining cap 114 is provided on the side wall of the light box 102 corresponding to the part of the lamp body 110. The lamp body 110 is installed in the mounting hole provided on the side wall of the light box 102; the lamp body 110 includes a rear shell 111, a lamp plate 112, and a transparent cover 113. The rear shell 111 has a vertically arranged "bowl"-shaped structure. The lamp plate 112 is installed inside the rear shell 111. The transparent cover 113 covers the opening side of the rear shell 111 to protect the lamp plate 112 inside the rear shell 111. In addition, as Figure 4 As shown, a plurality of LED beads 115 are provided on the side of the lamp panel 112 facing the transparent cover 113.
[0025] exist Figure 1 In the illustrated embodiment, there are three light boxes 102, which are stacked. Thus, there are three lamp bodies 110 on each side, each responsible for illuminating a corresponding color: red, yellow, or green.
[0026] It should be understood that in some other embodiments, the number of light boxes 102 may also be one. In this case, the number of lamp bodies 110 on each side is one, and this one lamp body 110 can complete the lighting work of red, yellow and green colors.
[0027] The present invention also equips traffic lights with photovoltaic panels 103, such as... Figure 1 As shown, the photovoltaic panel 103 is disposed on an inclined surface on one side of the base 100, and the interior of the base 100 is an intermediate structure for storing the battery. The battery is connected to the photovoltaic panel 103 to store the electrical energy generated by the photovoltaic panel 103.
[0028] In addition, the lamp body 110 has a self-illuminating area and a supplementary lighting area inside. For example... Figure 3 As shown, the traffic signal light also includes a light guide mechanism 130, which has a light-collecting end and a light-guiding end. In the two lamp bodies 110 arranged opposite each other, the light-collecting end is set for the illumination area of one lamp body 110, and the light guide end is set for the supplementary lighting area of the other lamp body 110; the light guide end guides the light collected by the light-collecting end to the supplementary lighting area, so that the corresponding lamp body 110 can be lit in the power-off state.
[0029] like Figure 3 As shown, the light guide mechanism 130 includes a light guide tube 131 with one end located inside the light box 102 and the other end penetrating through the side wall of the light box 102. The inner wall of the light guide tube 131 is provided with a reflective coating. Furthermore, the end of the light guide tube 131 penetrating the light box 102 is a light-collecting end, extending into the illumination area of the lamp body 110. The light guide mechanism 130 also includes a light guide strip 132 with one end located inside the light guide tube 131 and the other end extending into the supplementary lighting area. The end of the light guide strip 132 corresponding to the supplementary lighting area is the light guide end. The light guide strip 132 can be made of materials such as PVC, TPU, or optical fiber. Specifically, for example... Figure 6 As shown, both ends of the light guide tube 131 are provided with end caps. The end cap corresponding to the light-collecting end of the light guide tube 131 is a transparent cap 134, and the other end cap is a sealing cap 133. The difference between the two is that the transparent cap 134 allows light to enter the light guide tube 131, while the sealing cap 133 is a non-transparent structure used to prevent light from escaping from the light guide tube 131. Next, one end of the light guide strip 132 passes through the sealing cap 133 and is located inside the light guide tube 131. Furthermore, the end of the light guide strip 132 is flush with the side wall of the sealing cap 133, so that light from the light guide tube 131 can enter from the end of the light guide strip 132.
[0030] In addition, the light-collecting end of the light guide tube 131 is inclined, specifically in a tilted state where the side closer to the lamp body 110 is higher and the other side is lower (see reference). Figure 6 This design allows the light-collecting end of the light guide tube 131 to be positioned towards the lamp body 110, thereby reflecting the light emitted by the lamp body 110 into the light guide tube 131.
[0031] Furthermore, to improve the brightness of the supplementary lighting area, the present invention also optimizes the design of the lamp body 110. Specifically, a high-brightness area (corresponding to...) is set on the lamp panel 112. Figure 4 and Figure 5 Position A in the light guide tube 131 corresponds to the light-collecting end of the high-brightness area. A high-brightness LED 117 is then placed within this area, with the brightness of the LED 117 exceeding that of the LED 115. See the following embodiment for details: like Figure 4 In the embodiment shown, the high-brightness area is located inside the lamp board 112, and then the lamp beads 115 located in the high-brightness area are upgraded to high-brightness lamp beads 117. like Figure 5 In the illustrated embodiment, one side of the lamp panel 112 protrudes outward to form a protrusion, and a high-brightness LED bead 117 is disposed within the protrusion, with the high-brightness area located within the protrusion. In this embodiment, the protrusion is provided to prevent the light-collecting end of the light guide tube 131 from being in front of the lamp panel 112, thereby reducing the obstruction of the light-collecting end of the light guide tube 131 to the line of sight.
[0032] Furthermore, in the two embodiments described above, the angle of the high-brightness LED 117 is set corresponding to the light-collecting end of the light guide tube 131. For example... Figure 6 As shown, the high-brightness LED 117 can be tilted upwards, and the light refraction path at this time is referenced. Figure 6 The dashed arrow in the middle.
[0033] It should be noted that the light-collecting end of the light guide tube 131 can also be configured as a "U-shaped" structure to block external light (such as sunlight) and made of an opaque material, so that the light-collecting end of the light guide tube 131 and the high-brightness lamp bead 117 can be covered together. In this way, external sunlight cannot enter the interior of the light guide tube 131, improving the quality of light guidance.
[0034] like Figure 2 As shown, a substrate 120 is disposed inside the rear housing 111. The substrate 120 is located between the rear housing 111 and the lamp panel 112 and is used to fix the light guide strip 132. One end of the light guide strip 132 passes through the rear housing 111 and the substrate 120. Then as... Figure 4 and Figure 5 As shown, the side wall of the lamp panel 112 has multiple light-transmitting grooves 116 corresponding to the light guide strip 132. The portion of the lamp panel 112 corresponding to the light-transmitting grooves 116 is the supplementary lighting area, and the remaining portion is the self-illuminating area. The LED beads 115 are disposed within the self-illuminating area. The shape of the supplementary lighting area can be set according to the state of the light guide strip 132. For example: exist Figure 7 In the illustrated embodiment, one end of the light guide strip 132 is bent on the side of the substrate 120 facing the lamp panel 112. At this time, the light transmission groove 116 is an arc-shaped strip structure. In this embodiment, the light guide strip 132 also emits light during the light guiding process. Therefore, the light is emitted through the side of the light guide strip 132 and then passes through the light transmission groove 116.
[0035] exist Figure 8 In the illustrated embodiment, the end face of the light guide strip 132 penetrating the substrate 120 is parallel to the side surface of the lamp panel 112. In this case, the light transmission groove 116 has a hole-like structure. In this embodiment, light is emitted through the end of the light guide strip 132 and then passes through the light transmission groove 116.
[0036] It should be noted that the substrate 120 allows the light guide strip 132 to be disconnected from the lamp board 112, thereby facilitating the subsequent maintenance and replacement of the lamp board 112.
[0037] The specific principles of traffic lights will be explained in more detail below: refer to Figure 9 When the lamp body 110 in the corresponding direction S cannot be lit, but the lamp body 110 in the corresponding direction N can be lit, the light guide tube 131 set in direction N will guide part of the light in direction N into the light guide tube 131. At this time, the reference... Figure 6The high-brightness LED 117 at the corresponding direction N illuminates the light-receiving end of the light guide tube 131. The light is then reflected to the other end by the reflective coating inside the light guide tube 131. The reflected light then enters through one end of the light guide strip 132. Since the other end of the light guide strip 132 at the corresponding direction N is inside the lamp body 110 at the corresponding direction S, the light guide strip 132 itself illuminates. The light exits through the side or end of the light guide strip 132 and then passes through the light transmission groove 116. In this way, the lamp body 110 at the corresponding direction S is illuminated, and people can see the light through the light transmission groove 116. Furthermore, the color of the light inside the light guide strip 132 matches the color illuminated by the lamp body 110.
[0038] In other words, the light guide mechanism 130 can create a light guiding channel between two opposing lamp bodies 110, so that the light emitted by one lamp body 110 can be guided by the light guide mechanism 130 to the other lamp body 110. Thus, when one lamp body 110 cannot be lit normally, the light guide mechanism 130 can be used to enable the back cover 111 to continue to emit light, realize temporary emergency command, and improve the passage efficiency in the process of obtaining maintenance parts.
[0039] Furthermore, to further improve emergency response efficiency. (Reference) Figure 10 In this invention, the support rod 101 and the base 100 are rotatably connected. The bottom end of the support rod 101 extends into the base 100. A motor 104 is also installed inside the base 100. The motor 104 drives the support rod 101 to rotate by a preset angle, which is 90 degrees. The motor 104 and the support rod 101 are connected via a gear set.
[0040] In this way, reference Figure 9 Assuming that only the light 110 in the direction N can be lit normally, the light 110 in the direction S can also be lit under the action of the light guide mechanism 130, thus realizing traffic control in the north-south direction. Then, by controlling the support rod 101 to rotate 90 degrees through the motor 104, traffic control in the east-west direction can be achieved. During this process, the light 110 in the direction N can be adjusted to a continuously lit green light state.
[0041] In summary, when the lamp body 110 is damaged in multiple ways, the lamp body 110 is driven to rotate by the motor 104. By coordinating the rotation with the light guide mechanism 130, traffic control in multiple directions can be achieved, thereby further improving the command efficiency in emergency scenarios.
[0042] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
