Description

Technical Field

[0001] This invention relates to the field of warning light technology, specifically to a hexahedral warning light. Background Technology

[0002] Warning lights, as core equipment widely used in various warning scenarios, directly affect the efficiency of warning information transmission due to their coverage and stability. Existing warning lights mainly suffer from two types of structural defects: one is a cylindrical structure, where the light is evenly distributed 360 degrees, resulting in weak directional indication and difficulty in accurately conveying warning information in a specific direction. The other is a square structure, where the warning surface consists of four sides joined end-to-end, creating blind spots at the junctions of adjacent warning surfaces, thus limiting the warning angle and resulting in a large warning blind zone.

[0003] Meanwhile, existing warning lights generally suffer from poor heat dissipation performance, generating high levels of heat during operation. This heat tends to accumulate and cause a decrease in luminous efficiency. In severe cases, it can even lead to rapid aging and failure of the warning light source module, directly affecting the light intensity and lifespan of the warning light. Summary of the Invention

[0004] The purpose of this invention is to provide a hexahedral warning light, which has six warning faces, a small blind spot, strong directional indication, and is equipped with a heat sink for good heat dissipation, thus extending the service life of the warning light.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A hexahedral warning light includes a base and a light distribution lens covering the base. The light distribution lens contains a warning light source module and a warning light driver board mounted on the base. The light distribution lens also contains an inner lamp cover, a heat sink, and a heat sink base plate. The heat sink has a hexahedral structure, including six rectangular faces connected end to end. The heat sink is mounted on one side of the heat sink base plate, and the other side of the heat sink base plate is connected to the warning light driver board. The warning light source module has six components and is correspondingly connected to the outer surfaces of the six rectangular faces of the heat sink. The inner lamp cover also has six components and is respectively covering the periphery of the warning light source module.

[0006] Preferably, the radiator is provided with supporting ribs inside, which extend from the center of the radiator to the intersection of the two rectangular surfaces of the radiator, dividing the radiator into six triangular regions.

[0007] Preferably, the warning light source module includes a circuit board with LED beads arranged in at least one row, each row having a different color and the LED beads being evenly distributed. The light distribution lens includes an inner light distribution lens and an outer light distribution lens. The inner light distribution lens is made of transparent material, and the outer light distribution lens is made of opaque material. The outer light distribution lens is fitted and fixed around the inner light distribution lens. The outer light distribution lens has light-transmitting holes corresponding to the positions of the LED beads, and the number of light-transmitting holes is the same as the number of rows of LED beads.

[0008] Preferably, the LED beads are evenly arranged in three rows, and each row is evenly arranged with three LED beads.

[0009] Preferably, the inner lamp cover includes a side plate, a top plate, a bottom plate, and a front plate. The inner lamp cover forms an enclosing structure through the side plate, top plate, bottom plate, and front plate, and the enclosing structure covers the periphery of the warning light source module. The sidewalls of the inner lamp cover have an array of rectangular protrusions.

[0010] Preferably, at the intersection of every two adjacent rectangular faces of the heat sink, a warning light source module mounting slot and an inner lamp cover mounting slot are provided along the extension direction of the support rib. The warning light source module is inserted into the warning light source module mounting slot, and the side of the inner lamp cover is inserted into the inner lamp cover mounting slot.

[0011] Preferably, it also includes a heat-conducting sheet, which is disposed between the heat sink base plate and the warning light drive plate.

[0012] Preferably, the radiator base plate, heat-conducting fins, and warning light driver board are all circular plates; an inner lampshade retaining groove and a warning light source module retaining groove are provided on the radiator base plate, heat-conducting fins, and warning light driver board; a first protrusion is provided below the warning light source module, the first protrusion is inserted into the warning light source module retaining groove, and the first protrusion is adapted to the warning light source module retaining groove; a second protrusion is provided on both sides of the bottom of the inner lampshade, the second protrusion is inserted into the inner lampshade retaining groove, and the second protrusion is adapted to the inner lampshade retaining groove; the warning light source module and the warning light driver board are soldered together; the warning light driver board includes a command receiver.

[0013] Preferably, the heat sink is made of 1060 aluminum; the circuit board and the warning light driver board are both aluminum plates.

[0014] Preferably, an upper bolt mounting hole and a lower bolt mounting hole are provided at the intersection edge of every two adjacent rectangular faces of the heat sink; the upper bolt mounting hole is located at the top of the heat sink, and a first bolt is screwed into the upper bolt mounting hole, with the head of the first bolt located at the top of the inner lamp cover and the warning light source module; a second bolt passes through the warning light driver plate, the heat conduction plate and the heat sink base plate and is screwed into the lower bolt mounting hole; a protruding post is provided on the base, and a protruding post bolt mounting hole is provided inside the protruding post, and a third bolt passes through the heat sink base plate, the heat conduction plate and the warning light driver plate and is screwed into the protruding post bolt mounting hole.

[0015] In the above technical solution, six warning light source modules are set up to reduce the warning blind spot. Each warning light source module includes three rows of LEDs of different colors, with three LEDs evenly distributed in each row. A light-transmitting hole is set on the outer light distribution lens corresponding to the position of each row of LEDs, allowing the light reflected and refracted by the inner lampshade to pass through the light-transmitting hole, achieving directional output of different colored warning lights, improving the warning visibility in specific directions, and solving the problems of weak directional indication and scattered light in traditional warning lights, ensuring accurate transmission of different warning levels. The inner lampshade is an enclosed structure including side panels, top panel, bottom panel, and front panel, with light distribution patterns on both the inner and outer side walls, achieving concentrated guidance of the LED light, enhancing the reflection and refraction effect to improve light penetration in complex environments, and simultaneously protecting the warning light source modules.

[0016] By using 1060 aluminum, a material with high thermal conductivity, as the heat sink, which is a hexahedral structure consisting of six rectangular faces connected end to end, with each of the six rectangular faces corresponding to the warning light source module, and by incorporating supporting ribs in the middle of the heat sink, the internal space of the heat sink is divided into six regions with equilateral triangles in cross-section. This allows the heat generated by the warning light source module during operation to be quickly conducted to the rectangular faces, where heat exchange can be fully achieved with the air within the equilateral triangle regions. The supporting ribs not only strengthen the overall structural strength of the heat sink to prevent deformation but also facilitate the even diffusion of heat within the heat sink, improving overall heat dissipation efficiency. This solves the problem of heat accumulation in traditional warning lights leading to decreased luminous efficiency and aging failure of the light source module, thereby enhancing the illumination intensity and lifespan of the warning light.

[0017] By providing mounting slots for the warning light source module and the inner lamp cover along the edge at the intersection of adjacent rectangular surfaces of the heat sink, the components are embedded accordingly, improving connection stability and preventing vibration-induced loosening. Furthermore, by creating bolt mounting holes at the intersection of adjacent rectangular surfaces of the heat sink, and using the first bolt to limit the top of the warning light source module and the inner lamp cover, a stable overall structure is formed, improving vibration resistance and preventing component displacement.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings: like Figures 1 to 11 As shown, a hexahedral warning light includes a base 1 and a lens 2 covering the base 1. Both the base 1 and the lens 2 are basically hexagonal prisms, and a protruding ridge 211 is provided along the bottom circumference of the lens 2. A groove 11 that is interference-fitted with the protruding ridge 211 is provided along the top edge of the base 1. The base 1 and the lens 2 are detachably connected by inserting the protruding ridge 211 into the groove 11.

[0021] Between the base 1 and the lens 2, there is a heat sink 3, a heat sink base plate 4, a heat-conducting plate 5, a warning light source module 6, and a warning light driver board 7. The heat sink 3 is a hexahedral structure made of 1060 aluminum, comprising six rectangular faces 31 joined end-to-end. Compared to the four warning faces of traditional square warning lights, the six joined rectangular faces 31 reduce blind spots at the intersections of adjacent faces, allowing for more comprehensive coverage of the warning light, reducing blind spots, and improving all-around warning effectiveness. Inside the heat sink 3, there are supporting ribs 32 extending from the center of the heat sink 3 towards the intersection of adjacent rectangular faces 31, dividing the heat sink 3 into six equilateral triangular areas. The 1060 aluminum material has excellent thermal conductivity, allowing the six rectangular faces 31 to fully conform to the warning light source module 6, quickly dissipating the heat generated by the warning light source module 6 during operation. The internal support ribs 32 not only strengthen the overall structural strength of the radiator 3 and reduce deformation caused by vibration or external force during use, but also help the heat to spread evenly inside the radiator 3, improve heat exchange efficiency, and reduce the accumulation of heat.

[0022] At the intersection of every two adjacent rectangular faces 31 of the heat sink 3, along the extension direction of the support rib 32, there is a warning light source module mounting slot 33. The warning light source module 6 is a long, narrow slot. There are six warning light source modules 6, all of which are identical and include a circuit board 61. The circuit board 61 is made of aluminum, providing both structural strength and thermal conductivity. LED beads 62 are evenly arranged in three rows on the circuit board 61, with three LED beads 62 in each row. Each row of LED beads 62 has a different color. Different colored LED beads 62 correspond to different levels of warning information. The evenly distributed arrangement ensures more balanced light output, facilitating accurate transmission of different warning needs. During installation, the two sides of the circuit board 61 slide down along the top of the warning light source module mounting slot 33 and are inserted between the two slots, so that when the warning light source modules 6 are installed on the heat sink 3, the six warning light source modules 6 are completely flush with the six rectangular faces 31 of the heat sink 3.

[0023] At the intersection of every two adjacent rectangular faces 31 of the heat sink 3, an inner lampshade mounting groove 34 is provided along the extension direction of the support rib 32. The inner lampshade mounting groove 34 is also a long strip through groove. There are also six inner lampshades 8, which cover the periphery of six different warning light source modules 6. The inner lampshade 8 includes a side plate 81, a top plate 82, a bottom plate 83, and a front plate 84. The above plates form an enclosing structure, covering the periphery of the corresponding warning light source module 6, which can provide comprehensive protection for the warning light source module 6 and reduce the impact of external dust intrusion and minor collisions on the module. At the same time, the distance between the lamp bead 62 and the inner wall of the inner lampshade 8 is increased to reserve sufficient space for light propagation, so that the light emitted by the lamp bead 62 can diffuse more smoothly. The side plate 81 of the inner lamp cover 8 extends outward to form a protruding strip 811 that fits the inner lamp cover mounting groove 34. The protruding strip 811 can slide down along the top of the inner lamp cover mounting groove 34 and be inserted between the two inner lamp cover mounting grooves 34, so that the six inner lamp covers 8 are mounted on the heat sink 3 and completely cover the six warning light source modules 6. The inner wall and outer wall of the inner lamp cover 8 are provided with different light distribution patterns (the light distribution patterns are existing technology and are not shown in the figure), which can further concentrate and guide the light, and enhance the reflection and refraction effect of the light.

[0024] The bottom of the radiator 3 is connected to the radiator base plate 4. On the other side of the radiator base plate 4, a heat-conducting fin 5 and a warning light driver plate 7 are sequentially arranged. The radiator base plate 4, heat-conducting fin 5, and warning light driver plate 7 are all circular plates, allowing for a more regular fit between the components, increasing the contact area, and facilitating smoother heat conduction. The heat-conducting fin 5 is sandwiched between the radiator base plate 4 and the warning light driver plate 7, enabling rapid heat conduction from the warning light driver plate 7 and preventing heat buildup from affecting its performance.

[0025] The radiator base plate 4, the heat-conducting sheet 5, and the warning light driver board 7 are all provided with warning light source module fixing slots 9 and inner lamp cover fixing slots 91. A first protrusion 63 is provided below the circuit board 61, which is adapted to and inserted into the warning light source module fixing slot 9 to achieve precise positioning of the warning light source module 6. Simultaneously, the warning light driver board 7 and the warning light source module 6 are connected by solder, ensuring stable circuit conduction and strengthening the connection between the two. Second protrusions 85 are provided on both sides of the bottom of the inner lamp cover 8, which are adapted to and inserted into the inner lamp cover fixing slots 91 of the radiator base plate 4. The inner lamp cover fixing slots 91 can fix the bottom of the inner lamp cover 8, improving the installation stability of the inner lamp cover 8.

[0026] In addition, at the intersection of every two adjacent rectangular faces 31 of the heat sink 3, upper bolt mounting holes 35 and lower bolt mounting holes 36 are provided; at both ends of the top of the circuit board 61, there are blocking strips 611, and the upper bolt mounting holes 35 are located on the top of the heat sink 3. The first bolt 351 is screwed into the upper bolt mounting hole 35, and the head of the first bolt 351 is located at the top of the inner lamp cover 8 and the blocking strip 611, which limits the top of the two. Together with the warning light source module mounting slot 33 and the inner lamp cover mounting slot 34 on the heat sink 3, they form a top-to-bottom correspondence, respectively limiting the bottom and top of the warning light source module 6 and the inner lamp cover 8, so that the two are firmly fixed on the heat sink 3 and prevent relative separation from the heat sink 3. The second bolt 361 passes through the warning light drive plate 7, the heat conduction plate 5 and the heat dissipation base plate 83 in sequence and is screwed into the lower bolt mounting hole 36, so that the heat sink 3 can be firmly connected.

[0027] A plurality of protruding posts 12 are provided on the base 1, preferably three, evenly distributed along the top circumference of the base 1. A bolt mounting hole 13 is provided inside the protruding post 12. A third bolt 14 passes through the radiator base plate 4, the heat-conducting fin 5, and the warning light drive plate 7, and is screwed into the bolt mounting hole 13. This allows the radiator base plate 4, the heat-conducting fin 5, and the warning light drive plate 7 to be fixed to the base 1.

[0028] The light distribution lens 2 includes an inner light distribution lens 21 and an outer light distribution lens 22, with a convex ridge 211 positioned below the inner light distribution lens 21. The inner light distribution lens 21 is made of transparent material, while the outer light distribution lens 22 is made of opaque material. The outer light distribution lens 22 is fitted and fixed around the inner light distribution lens 21. A light-transmitting hole 221 is provided on the outer light distribution lens 22 at a position corresponding to the position of the LED bead 62, and the number of light-transmitting holes 221 is the same as the number of rows of LED beads 62. The transparent inner light distribution lens 21 allows light emitted from the LED beads 62 to pass through smoothly, while the opaque outer light distribution lens 22 prevents irregular scattering of light. The light-transmitting holes 221 guide the light to pass through in a specific direction, improving the warning visibility in a specific direction and solving the problem of weak directional indication in traditional warning lights.

[0029] In this embodiment, a command receiver is provided on the warning light driver board 7, which can receive external control commands to control the lighting of different colored LED beads 62, meeting the needs of diverse warning scenarios. Meanwhile, both the circuit board 61 and the warning light driver board 7 are made of aluminum plates, and they are soldered together to ensure stable circuit connection.

[0030] During use, the external control device sends a control signal to the warning light driver board 7 via the command receiver, driving the corresponding colored LED beads 62 to light up. After being reflected and refracted by the inner lamp cover 8, the light is directionally transmitted through the light-transmitting hole 221 on the outer lens 22, realizing the transmission of warning information in a specific direction and at a specific level. For example, in this embodiment, the three rows of LED beads 62 set on the circuit board 61 are respectively set to red, green, and yellow. In actual application, the corresponding control signal can be sent to the command receiver via the external control device according to the needs of the site environment to flexibly light up the appropriate LED beads 62: when a high-risk warning is needed in an emergency, the red LED beads 62 can be lit. When it is necessary to remind the surrounding area to avoid danger, the yellow LED beads 62 can be lit. When it is necessary to convey information such as safe passage or normal operation, the green LED beads 62 can be lit. The color differentiation realizes the accurate transmission of warning levels and adapts to diverse usage scenarios. If the warning light needs to be maintained or repaired, the lens 2 and related bolts can be disassembled in sequence, and the components can be cleaned, replaced, or repaired. After maintenance, it can be reassembled according to the assembly steps.

[0031] This embodiment is merely an illustration of the concept and implementation of the present invention and is not intended to limit it. Under the concept of the present invention, technical solutions without substantial changes are still within the scope of protection.
