Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tunnel lighting fixtures, and in particular relates to an adjustable angle tunnel lighting fixture. Background Technology
[0002] Tunnel lighting fixtures are specialized devices used for tunnel illumination to address the "black hole effect" or "white hole effect" caused by sudden changes in brightness when vehicles enter or exit tunnels. These fixtures need to provide sufficient illumination to ensure drivers can clearly see road conditions and other vehicles within the tunnel. Simultaneously, the lighting effect must take into account factors such as light reflection and refraction within the tunnel to avoid glare or shadows.
[0003] The angle of the lights inside the tunnel may need to be changed or further fine-tuned in some cases.
[0004] To adapt to special road conditions or construction needs: For example, if a special situation occurs in a section of the tunnel, such as road maintenance or partial renovation, it may be necessary to temporarily change the angle of the lamps to better ensure lighting in the specific area.
[0005] Lighting effect optimization: As usage time increases or new research discoveries are made, it may be found that the original lamp angle settings are not optimal. In order to improve the overall lighting quality and uniformity, secondary adjustments may be made.
[0006] Technological upgrades: When new lighting technologies or control strategies emerge, the angle of the luminaires may need to be reset to better match the new technologies;
[0007] Currently, most tunnel lights are equipped with multiple light panels to increase brightness. However, adjusting the angle of the lights requires specialized tools such as wrenches to disassemble and reassemble them, making the process cumbersome. Furthermore, since the angles of multiple light panels on a single light fixture are often adjusted simultaneously, the relative angles between the panels remain constant. This can lead to overly diffused light, resulting in poor illumination or dark areas, which can compromise safe driving. Utility Model Content

[0010] Preferably, the light panels are configured in three groups and are equidistantly distributed along the length of the side panels.
[0011] Preferably, the outer circumference of the rotary latch is uniformly surrounded by several arc-shaped grooves, each arc-shaped groove extending along the axial direction of the rotary latch; the locking member includes a mounting block and at least one ball, the mounting block is fixedly mounted on the corresponding side plate, the mounting block has an inner through hole, the rotary latch is inserted into the inner through hole, and the ball slides radially along the inner through hole in the mounting hole inside the mounting block; the ball elastically abuts against one of the arc-shaped grooves through an elastic element to achieve locking of the rotary latch and the locking member.

Additionally, by controlling the on / off state or brightness of different light panels individually, more precise lighting adjustments can be achieved to adapt to different times of day and traffic conditions. If one light panel malfunctions, the others can still provide a certain level of illumination, minimizing the impact on overall lighting. Attached Figure Description

Detailed Implementation
[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0029] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0030] Example 1:
[0031] Reference Figures 1 to 6 As shown, this utility model embodiment provides an adjustable angle tunnel lighting fixture, including a mounting plate 1 and several lamp plates 2. The mounting plate 1 has two side plates 11 symmetrically arranged on its inner end. Each lamp plate 2 has a first rotating shaft 21 and a second rotating shaft 22 symmetrically arranged at both ends. The first rotating shaft 21 is inserted into one of the side plates 11 and rotatably connected to it. A columnar rotating latch 3 is fixedly sleeved on the second rotating shaft 22. The rotating latch 3 passes through the other side plate 11 and rotatably connected to it. Specifically, the lamp plates 2 are configured in three groups and are equidistantly distributed along the length of the side plates 11. The cooperation of the three groups of lamp plates 2 improves the lighting range and brightness, can gather more light energy, and make the tunnel brighter, especially in some long tunnels or in poor lighting conditions, which can better meet the lighting needs.
[0032] A locking element 4 that cooperates with the rotary lock 3 is also fixedly connected to the side plate 11 located at the second rotating shaft 22. The rotary lock 3 locks with the corresponding locking element 4 and has multiple locking points.
[0033] In this embodiment, by rotatably connecting several light panels 2 to the front end of the corresponding mounting plate 1, and by having the operator simply rotate the rotating latch 3 to place them in different locking positions, the angle of the light panels 2 can be adjusted without the need for special tools such as wrenches. This makes adjusting the illumination angle of the light panels 2 more convenient. By setting multiple light panels 2, each with an adjustable angle, multiple light panels 2 can emit light from different angles, making the lighting in the tunnel more uniform, reducing differences in brightness, enhancing the uniformity of lighting, and improving driving safety and comfort. In addition, by controlling the on / off state or brightness of different light panels 2 separately, more precise lighting adjustment can be achieved to adapt to different time periods and traffic conditions. If one light panel 2 malfunctions, the other light panels 2 can still provide a certain level of lighting, reducing the impact on the overall lighting.
[0034] Specifically, the outer circumferential surface of the rotary latch 3 is uniformly provided with a plurality of arc-shaped grooves 31, each arc-shaped groove 31 extending along the axial direction of the rotary latch 3; the locking member 4 includes a mounting block 41 and at least one ball 42, the mounting block 41 is fixedly mounted on the corresponding side plate 11, the mounting block 41 is provided with an inner through hole 411, the rotary latch 3 is inserted into the inner through hole 411, and the ball 42 slides radially along the inner through hole 411 in the mounting hole 412 inside the mounting block 41; the ball 42 elastically abuts against one of the arc-shaped grooves 31 through an elastic member 43, for realizing the locking of the rotary latch 3 and the locking member 4, and a preferred embodiment of the elastic member 43 can be a high-strength spring, so that the ball 42 stably elastically abuts against the corresponding arc-shaped groove 31;
[0035] In this embodiment, the rolling balls 42, the corresponding mounting holes 412, and the elastic elements 43 are all configured in three sets and evenly distributed on the mounting block 41. Under the action of the spring, the three rolling balls 42 can elastically abut against the corresponding arc-shaped grooves 31, thereby locking the rotary lock 3, stabilizing the second rotating shaft 22, and ensuring that the lamp panel 2 will not deflect at an angle when not subjected to external force. When it is necessary to adjust the angle of the lamp panel 2, the operator only needs to rotate the rotary lock 3 to make the multiple rolling balls 42 fully retract to their corresponding positions. Inside the mounting hole 412, the ball 42 abuts against the outer circumferential surface of the rotary lock 3. When the ball 42 moves to another arc-shaped groove 31 as the rotary lock 3 rotates, the ball 42 is pushed out again by the spring force and abuts against the arc-shaped groove 31 directly opposite it, thus locking the rotary lock 3 again. That is, when the ball 42 moves to different arc-shaped grooves 31, the rotary lock 3 is in different multi-level locking positions. After adjusting the angle of the lamp panel 2, the angle of the lamp panel 2 is automatically locked, making the operation convenient when adjusting the angle of the lamp panel 2.
[0036] Specifically, such as Figure 3 and Figure 4 As shown, if the diameter of the ball 42 is smaller than the diameter of the arc groove 31, when the ball 42 reaches one of the multi-level locking points, the ball 42 will still have some room for movement within the corresponding arc groove 31, which will cause the lamp panel 2 to still wobble slightly after locking. If the diameter of the ball 42 is larger than the diameter of the arc groove 31, the ball 42 will not be able to fit properly into the arc groove 31, resulting in unstable locking of the rotary lock 3. Therefore, by matching the diameter of the ball 42 with the diameter of the arc groove 31, the ball 42 can fit properly into the arc groove 31, ensuring the locking force and preventing the lamp panel 2 from still wobble after locking.
[0037] Specifically, the inner wall of the mounting hole 412 near the inner through hole 411 is configured with an inwardly transitioning inner arc surface 413, the minimum diameter of which is smaller than the diameter of the ball 42; when the ball 42 is attached to the inner arc surface 413 by the elastic member 43, at least a portion of the ball 42 is located in the inner through hole 411, so that the locking member 4 is an integral structure when not installed, preventing the ball 42 from falling out of the corresponding mounting hole 412.
[0038] The end of the rotary latch 3 is equipped with a knob 32 for easy operation by staff.
[0039] Example 2:
[0040] like Figure 1 As shown, based on Embodiment 1, the mounting block 41 can also be configured as a split structure, consisting of an inner mounting block 414 and an outer mounting block 415. The mounting hole 412 is located on the inner mounting block 414 and extends to the outer peripheral wall of the inner mounting block 414. The outer mounting block 415 slides into the outer side of the inner mounting block 414 along the axial direction and is fixedly connected to the inner mounting block 414 by bolts. This facilitates the installation or removal of the ball 42 or the elastic element 43, improving convenience in assembly process and subsequent maintenance.
[0041] In addition, a mounting bracket 5 is provided on the outer end of the mounting plate 1. The mounting bracket 5 is connected to the mounting plate 1 by bolts. The mounting bracket 5 can be fixedly installed on the mounting plate 1 by tightening the bolts and nuts. The mounting bracket 5 is fixedly connected to the wall or tunnel wall. When assembling the mounting plate 1, the overall angle of the mounting plate 1 can also be adjusted to determine the approximate angle of the light. When fine-tuning the angle of the light plate 2 later, only the knob 32 needs to be rotated.
[0042] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
