Detailed Description of the Preferred Embodiments

[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] It should be noted that the terms "comprising" and "having" in the description and claims of the present utility model, and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally further include steps or units not listed, or may optionally further include other steps or units inherent to these processes, methods, products or devices. Terms such as "arranged" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. The orientations or positions indicated by terms such as "upper", "lower", "left", "right", "front", "rear", "bottom", etc. are based on the orientations or positions shown in the drawings, and are only for convenience of description and should not be construed as a limitation to the technical solution of the present invention.

[0033] It should be noted that as the core of the lighting system, the installation process of tunnel lamps not only involves the fixation of the lamps themselves, but also includes the stable installation of the driving power supply and the precise adjustment of the irradiation angle of the lamps. Therefore, the installation method of tunnel lamps often involves the combined use of angle adjustment parts, lamp installation brackets and power supply fixing brackets. The assembly and use of multiple components meet the basic installation requirements of tunnel lamps, but the assembly of multiple components increases the operation steps and complexity in the installation process of tunnel lamps, and the use of multiple components increases the installation cost and working time cost.

[0034] After the tunnel lamps are installed, in order to better meet the lighting requirements of the tunnel, it is necessary to adjust the irradiation angle of the lamps. In order to complete the angle adjustment of the lamps, two parts, namely the lamp installation bracket and the angle adjustment part, are required to complete;

[0035] In order to avoid the heat superposition of the lamp beads and the driving power supply, a power supply fixing bracket is added to the surface of the tunnel lamp to separate the driving power supply from the lamp beads, which can greatly reduce the heat accumulation of the driving power supply and improve the service life of the driving power supply.

[0036] As Figures 1-7 shown, this embodiment provides a tunnel lamp. The angle adjustment part 20 is in a Z shape. Its mutually parallel first surface 21 is connected to the tunnel lamp main body 10, its mutually parallel second surface 22 is connected to the driving power supply 17 of the tunnel lamp main body 10, and the third surface 23 is connected to the lamp installation bracket 30. The angle adjustment part 20 directly provides support for the driving power supply 17, separating the driving power supply 17 from the tunnel lamp main body 10. While improving the service life of the driving power supply 17, the structure of the tunnel lamp is optimized, the materials of the tunnel lamp are reduced, and the cost of the tunnel lamp is greatly reduced.

[0037] Specifically, the tunnel lamp includes a tunnel lamp main body 10, an angle adjusting member 20, and a lamp mounting bracket 30. The angle adjusting member 20 is in a "Z" shape. The first surface 21 of the angle adjusting member 20 is connected to the tunnel lamp main body 10, and the second surface 22 of the angle adjusting member 20 that is parallel to the first surface 21 is connected to the driving power supply 17 of the tunnel lamp main body 10. The lamp mounting bracket 30 is in an "L" shape and is rotatably connected to the third surface 23 of the angle adjusting member 20 for adjusting the mounting angle of the tunnel lamp main body 10.

[0038] The first surface 21 and the second surface 22 of the angle adjusting member 20 are parallel to each other. The third surface 23 connects the first surface 21 and the second surface 22. The tunnel lamp main body 10 is connected to the first surface 21 of the angle adjusting member 20, and the driving power supply 17 is connected to the second surface 22 of the angle adjusting member 20, thereby increasing the distance between the driving power supply 17 and the tunnel lamp main body 10 and increasing the air circulation space, which can effectively improve the heat dissipation efficiency and extend the service life of the driving power supply 17 and the tunnel lamp main body 10.

[0039] One surface of the lamp mounting bracket 30 is rotatably connected to the third surface 23 of the angle adjusting member 20, and the other surface of the lamp mounting bracket 30 is connected to the mounting platform of the tunnel lamp, thereby mounting the tunnel lamp on the external mounting platform.

[0040] In one embodiment, the lamp mounting bracket 30 of the tunnel lamp on the market is generally fixed on the surface of the radiator of the lamp with screws, and all the forces on the lamp are borne by the fixing screws. Therefore, the seismic resistance of the screws is crucial. Once the screws become loose, the lamp has the risk of falling.

[0041] In this embodiment, the tunnel lamp main body 10 includes a lighting mechanism and a radiator. The lighting mechanism is arranged on the front side of the radiator. The radiator includes a heat dissipation body 13 and a plurality of heat dissipation fins 14 connected to one side of the heat dissipation body 13 at one end. The plurality of heat dissipation fins 14 are arranged parallel to each other. The ends of at least two heat dissipation fins 14 away from the heat dissipation body 13 are bent towards each other to form a mounting portion 141, and the mounting portion 141 is connected to the first surface 21 of the angle adjusting member 20 that is parallel to each other. Hook portions 211 extend outwards from both ends of the first surface 21 of the angle adjusting member 20, and the hook portions 211 slide into the mounting portion 141 and are connected to the mounting portion 141.

[0042] Specifically, the hook portions 211 on the first surface 21 of the angle adjusting member 20 slide along the mounting portion 141 formed by the two heat dissipation fins 14. After sliding to a proper position, the angle adjusting member 20 is fixed with screws. At this time, the fixing screws are only used for limiting and do not participate in bearing the force. Even if the screws are loosened by vibration, the lamp will not fall due to the loosening of the screws, greatly improving the safety of the lamp.

[0043] It should be noted that there are two angle adjustment members 20 , the distance between the two adjustment members is consistent with the length of the driving power source 17 , and the third surfaces 23 of the two angle adjustment members 20 are respectively connected to the two ends of the driving power source 17 to provide support for the driving power source 17 .

[0044] In one embodiment, the lens 12 generally used in existing tunnel lamps is a peanut-sized convex lens 12 with an uneven surface. Due to the passage of vehicles inside the tunnel, there is a lot of dust in the tunnel, and the uneven lens 12 surface is easy to accumulate, resulting in a significant reduction in the luminous flux of the lamp.

[0045] The lighting mechanism of this embodiment includes a lamp board 11 and a lens 12. The lamp board 11 is arranged on the side of the heat dissipation body 13 away from the heat sink 14, and the lamp board 11 is electrically connected to the driving power supply 17; the lens 12 is arranged on the side of the heat dissipation body 13 away from the heat sink 14 and covers the outer surface of the lamp board 11, and the surface of the lens 12 is flat.

[0046] The surface of the lens 12 is flat, and the smooth surface of the lens 12 can prevent dust accumulation and greatly improve the luminous flux of the lamp;

[0047] At the same time, the lens 12 adopts a large and small lens 12 design. When making a low-power tunnel lamp, a small flat lens 12 is used, and when making a medium-power (90-160 watt) tunnel lamp, a large flat lens 12 is used. This design can greatly reduce the processing and material costs of medium-power lamps while meeting the cost of low-power lamps.

[0048] In one embodiment, tunnel lights on the market are generally waterproofed by using waterproof silicone rings, and the installation of the silicone rings is a manual operation. The cost of the silicone rings is high, and the manual installation of the silicone rings is inefficient.

[0049] In this embodiment, a groove 121 is provided on one side of the lens 12 close to the light board 11, and the groove 121 is filled with waterproof glue, which is formed by solidifying liquid silicone rubber. An automated machine is used to inject waterproof silicone rubber into the groove 121 of the lens 12, thereby reducing material costs and realizing mass automated production.

[0050] In one embodiment, the lens 12 is buckled with the heat dissipation body 13. Specifically, a buckle is provided on the lens 12, and a buckle hole is provided at a corresponding position of the heat dissipation body 13, and the buckle is buckled with the buckle hole. After the lens 12 is glued, the lens 12 is turned over and aligned with the buckle hole on the heat dissipation body 13. The lens 12 can be installed by pressing the lens 12 buckle into place once using a device, which is simple and fast, greatly improving production efficiency. In other optional embodiments, the installation method of the lens 12 can be compatible with buckle connection and screw connection.

[0051] In one embodiment, the tunnel lamp body 10 further includes a first connecting member 15 and a second connecting member 16. The lamp mounting bracket 30 is mounted on the angle adjusting member 20 through the first connecting member 15, and the lamp mounting bracket 30 is rotatably connected to the angle adjusting member 20 through the second connecting member 16. The first connecting member 15 is an M8 fixing screw, and the second connecting member 16 is an M4 angle adjusting screw.

[0052] A plurality of positioning holes 31 are formed on the lamp mounting bracket 30 corresponding to the second connecting member 16 . The plurality of positioning holes 31 are arranged along the circumference of the second connecting member 16 and are connected in sequence.

[0053] With the first connecting member 15 as the center, the angle between two adjacent positioning holes 31 is 8° to 12°. For example, 11 positioning holes 31 are provided on the lamp mounting bracket 30, and with the first connecting member 15 as the center, the angle between two adjacent positioning holes 31 is 10°. Under this structure, the lamp mounting bracket 30 can rotate relative to the angle adjustment member 20 at an angle of -50°, -40°, -30°, -20°, -10°, 0°, 10°, 20°, 30°, 40° or 50°, and the elevation angle of the tunnel light can be accurately adjusted.

[0054] like Figure 7 As shown, it should be noted that when installing low-power (less than 80 watts) tunnel lamps, only the lamp mounting bracket 30 can be used for lamp installation and lamp angle adjustment, which simplifies the lamp structure and greatly reduces the cost of the lamp. At this time, the driving power supply 17 can be directly installed on the radiator.

[0055] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.

[0056] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
