Technical Field

[0001] The present invention relates to the technical field of tunnel lighting, in particular to a lighting lamp used in a highway tunnel. Background Art

[0002] During the use of highway tunnels, in order to meet the lighting needs inside the tunnel, it is necessary to evenly install lighting lamps on the tunnel wall to improve the safety of vehicles driving in the tunnel. Most existing tunnel lights are installed in an embedded and fixed manner, making it impossible to adjust the angle to meet different lighting needs.

[0003] Prior art 1 (application number: 201910920007.8, Chinese patent application date: September 26, 2019) discloses a lighting device for tunnel lighting with adjustable lighting angle, comprising a fixed plate, a base fixedly mounted on the left side of the fixed plate, a movable groove formed at the upper end of the base, a pulley movably mounted at the left end of the bottom of the base, the interior of the base being fixedly connected to a rotating shaft via a fixed rod, a gear rotatably connected to the rotating shaft, and a first movable rod rotatably connected to the rear end of the gear on the rotating shaft. This lighting device for tunnel lighting with adjustable lighting angle has an interference fit between the first connecting rod and the gear. When a push rod is pushed by a human, the second connecting rod is lifted upward, which drives the auxiliary rod to be lifted. The push rod begins to push to the left, and then the second connecting rod is lowered. The auxiliary rod is stuck in the tooth groove of the gear. When the push rod is pushed to the right by human power, the auxiliary rod drives the gear to rotate, thereby achieving the effect of changing the lighting angle.

[0004] Prior art 2 (Chinese patent application number: 201510021750.1, filed on January 15, 2015) discloses an LED tunnel light comprising a housing assembly, a light source module assembly, and a power supply assembly. The housing assembly comprises end caps, side beams, and an angle adjustment bracket. The end caps and side beams are connected to form a square frame, and the angle adjustment bracket is mounted on the vertical wall of the side beams. Power requirements can be adjusted by adjusting the length of the side beams. The power supply assembly comprises a driving power supply and a power supply mounting bracket, and is located between the two side beams. This tunnel light fixture has a simple assembly process, adjustable illumination angle, strong versatility, and a wide range of applications.

[0005] Prior art three (Chinese patent application number: 201611199021.6, filed on December 22, 2016) discloses a tunnel light with adjustable illumination angle and illumination state, as well as a tunnel light system and operating method. The system comprises: a brightness sensor signal transmitter connected to a central processing unit signal receiver; a signal transmitter emitting infrared signals to detect vehicle speed; a signal receiver receiving the signals transmitted by the transmitter; a signal receiver output connected to a central processing unit signal input; a central processing unit signal output connected to a drive control module signal receiver; and a drive control module drive signal output connected to a tunnel light signal receiver. A brightness sensor is placed outside the tunnel, and the sensor input adjusts the tunnel light's illumination at the tunnel entrance and exit. A sensing system is added within the tunnel light to detect traffic accidents. When a traffic accident occurs in the tunnel, the tunnel light changes its illumination state.

[0020] 1. An adjustment motor and a lamp body are provided.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figures 1-6 As shown, the existing road tunnel lighting is not convenient to use light at locations where lighting is not required after adjusting the angle during use, and cannot provide auxiliary lighting for adjacent fault lights. To solve this technical problem, this embodiment discloses the following technical content;

[0035] A lighting lamp for a highway tunnel includes a mounting frame 1 fixedly mounted to the tunnel wall by bolts, an adjustment base 2 being rotatably connected to the outer side of the mounting frame 1, an adjustment motor 3 being fixedly mounted to the outer side of the adjustment base 2, a lamp body 4 being rotatably connected to the outer side of the adjustment base 2, and a light-transmitting cover 5 being fixedly mounted to the lower end of the lamp body 4;

[0036] The light source further comprises: a reflective assembly, wherein two reflective assemblies are symmetrically arranged about the lamp body 4, and a transmission member is connected between the reflective assembly and the adjustment seat 2, and the reflective assembly is driven by the transmission member to be adjusted during the rotation of the adjustment seat 2;

[0037] The mounting frame 1 and the adjustment seat 2 are connected in a damped rotation manner, and the output end of the adjustment motor 3 is fixedly connected to the upper end of the lamp body 4, and the adjustment motor 3 drives the lamp body 4 to adjust the left and right tilt.

[0038] The reflective assembly includes an adjustment frame 6 elastically rotatably mounted on the outside of the lamp body 4, and the end of the adjustment frame 6 away from the lamp body 4 is fixedly connected to a first reflector 7, and the transmission part includes a first pull rope 8 wound around the shaft of the adjustment frame 6, and the upper end of the first pull rope 8 is fixedly connected to the outside of the adjustment seat 2. During the rotation of the lamp body 4, the two groups of adjustment frames 6 on both sides will rotate in opposite directions under the drive of the first pull rope 8.

[0039] The second reflector 10 is attached to the outer side of the first reflector 7 , and the mirror surfaces of the first reflector 7 and the second reflector 10 are opposite to each other.

[0040] Two sets of connecting rods 9 are symmetrically and elastically connected to the side surfaces of the first reflector 7 and the second reflector 10, and the two connecting rods 9 on the same side are arranged in parallel. A second pull rope 11 is wound around the outer side of the shaft of one of the connecting rods 9 located on the first reflector 7. At the same time, the upper end of the second pull rope 11 is fixedly connected to the outer side of the adjustment base 2. When the first reflector 7 rotates, the second pull rope 11 pulls the connecting rod 9 to rotate automatically.

[0041] After the first reflector 7 rotates, it is located below the side of the lamp body 4 , and the second reflector 10 is located above the first reflector 7 , and the first reflector 7 and the second reflector 10 cooperate to reflect the light of the lamp body 4 .

[0042] By adopting the above technical solution, the mounting frame 1 is installed on the tunnel wall with bolts, and the normal lighting angle of the lamp body 4 is adjusted by rotating the adjustment seat 2. When a lamp body 4 fails and goes out, the adjustment motor 3 on the adjacent lighting lamp of the extinguished lamp body 4 is controlled, so that the adjustment motor 3 drives the lamp body 4 to rotate around the adjustment seat 2, so that the lamp body 4 is slightly facing the direction of the faulty lamp. At this time, the shaft of the adjustment frame 6 close to the side of the faulty lamp will reel the first pull rope 8, and at the same time, the adjustment frame 6 will drive the first reflector 7 to rotate elastically, so that the first reflector 7 gradually moves to below the edge light of the lamp body 4. At this time, its reflective surface Towards the edge of the lamp body 4, the first reflector 7 can reflect the edge light of the lamp body 4, and as the first reflector 7 rotates and moves, the second pull rope 11 will pull the connecting rod 9 on the first reflector 7 to rotate elastically, thereby causing the second reflector 10 to gradually move away from the first reflector 7. At this time, the second reflector 10 can reflect and disperse the light reflected by the first reflector 7 again, thereby achieving auxiliary lighting for the lighting area required by the fault lamp, so that when the lamp fails, auxiliary lighting is achieved by sacrificing a certain lighting brightness to expand the lighting range, ensuring the normal passage of vehicles in the tunnel.

[0043] Example 2: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned Example 1. When adjusting the angle of existing highway tunnel lighting, it is inconvenient to automatically clean the dust attached to the outside of the lighting, thereby reducing the lighting brightness. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 2-Figure 3 and Figure 7-Figure 8 As shown;

[0044] The slide groove 15 is provided on the light-transmitting cover 5 , and a cleaning plate 16 is elastically and slidably provided in the slide groove 15 , and an air supply component is provided between the cleaning plate 16 and the reflective component to realize the driving of the cleaning plate 16 and the auxiliary air blowing cleaning.

[0045] The air delivery assembly includes a fixing frame 12 fixedly mounted on the outside of the first reflector 7, and the fixing frame 12 and the first reflector 7 are arranged parallel to each other, and an elastic air storage bag 13 is fixedly bonded to the side of the fixing frame 12 facing the first reflector 7, and the elastic air storage bag 13 is located between the second reflector 10 and the fixing frame 12. At the same time, the second reflector 10 squeezes the elastic air storage bag 13 on the outside of the fixing frame 12 during movement.

[0046] The gas delivery component also includes an elastic bellows 18 installed on the inner side of the slide groove 15, and the elastic bellows 18 and the elastic air storage bag 13 are connected through the gas delivery pipe 14. During the extension process of the elastic bellows 18, the cleaning plate 16 is pushed to slide along the slide groove 15. At the same time, a spring 17 is connected between the cleaning plate 16 and the inner wall of the slide groove 15.

[0047] The cleaning plate 16 slides in contact with the surface of the light-transmitting cover 5, and the cleaning plate 16 has a hollow structure. The cleaning plate 16 is evenly provided with air holes 19, and the air holes 19 face the surface of the light-transmitting cover 5. The air outflow rate of the air holes 19 is lower than the air transmission rate of the air transmission pipe 14 to the inner side of the elastic bellows 18.

[0048] By adopting the above technical solution, when the first reflector 7 and the second reflector 10 are adjusted, the second reflector 10 will move closer to the fixing frame 12, thereby cooperating with the fixing frame 12 to squeeze the elastic air storage bag 13, so that the gas in the elastic air storage bag 13 enters the elastic bellows 18 through the air pipe 14, and then enters the cavity of the cleaning plate 16 through the elastic bellows 18, and finally blows evenly to the surface of the light-transmitting cover 5 through the air holes 19 on the cleaning plate 16, thereby achieving air blowing and cleaning of the surface of the light-transmitting cover 5. Since the air outlet rate of the air holes 19 is lower than the air delivery rate of the air pipe 14, the elastic bellows 1 8, the air pressure inside gradually increases, thereby pushing the elastic bellows 18 to expand and extend. At this time, the elastic bellows 18 can push the cleaning plate 16 to slide along the slide groove 15. At this time, the cleaning plate 16 can scrape off the dust on the surface of the light-transmitting cover 5, thereby further improving the lighting effect of the lamp body 4. When the first reflector 7 and the second reflector 10 are reset, the elastic air storage bag 13 can be restored to inhale air, which is convenient for subsequent use. The reset first reflector 7 and the second reflector 10 are attached to each other, thereby protecting the reflective surface and avoiding dust adhesion that affects the reflection effect when it is used again.

[0049] The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0050] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
