[0029] In order to make the purpose, technical scheme and advantages of the embodiment of the present application clearer, the technical scheme of the embodiment of the present application will be clearly and completely described in conjunction with the drawings of the embodiment of the present application. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0030] Unless otherwise defined, the technical or scientific terms used herein shall have the common meanings understood by persons with ordinary skills in the field to which this application belongs. The words "first", "second" and similar words used in the patent application specification and claims of this application do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one" or "an" do not indicate a quantity limitation, but indicate the existence of at least one.

[0031] According to the diagram, a multi-purpose lighting system for use in a tunnel in the present utility model example includes a lighting fixture installation slot 10, a control device 20, a mounting substrate of a multi-color lighting lamp group sealed and mounted on the installation slot 10, and the installation slot 10 is equipped with a multi-directional adjustable bracket 30 mounted on the top or side wall of the tunnel. The present application has a lighting distribution system with ordinary white light illumination and red, green and yellow colors with traffic guidance functions, which overcomes the limitations of tunnel lighting in the prior art.

[0032] In this embodiment, the cross section of the installation slot 10 is an inverted trapezoid, which is generally wide at the top and narrow at the bottom. The front and rear edges of the slot opening of the installation slot 10 are provided with opposite card slots 11, and the two sides of the lamp bead substrate 12 are respectively embedded in the card slots 11; the left and right sides of the installation slot 10 are externally equipped with end caps 14; the bottom sides of the installation slot 10 are fixed with multi-directional adjustable brackets 30, and the adjustable brackets are used to install the installation slot 10 on the top or side wall of the tunnel.

[0033] Specifically, as shown in the figure, the card slot 11 and the installation slot body 10 are integrally formed, which is easy to manufacture and easy to seal the entire structure. The upper side of the card slot 11 that holds the lamp bead substrate 12 is convex upward to form an inverted V-shaped space 111, and the lower side is concave downward to form a V-shaped space 112. O-shaped strips 113 are embedded in the V-shaped space 112 and the inverted V-shaped space 111. The O-shaped strips 113 ensure the sealed installation of the card slot 11 and the lamp bead substrate 12. The use of such a hidden double-layer sealing protection improves reliability while ensuring the aesthetics of the overall structure. The O-shaped strip 113 is preferred, which has a simple structure, a stable cross-section, is not prone to distortion, and has the characteristics of self-positioning in conjunction with the V-shaped groove; the upper and lower O-shaped strips 113 form a double-layer seal, which is accurately and reliably positioned to ensure that the product sealing line and sealing pressure are consistent, thereby improving the stability of the product seal.

[0034] Specifically, the end surfaces of both sides of the installation groove body 10 are assembled with multiple components, such as profiles, glass, and rubber rings 142. There are assembly errors. In order to avoid the influence of assembly errors on waterproof sealing, end caps 14 are used for sealing. A rubber ring 142 is provided on one side of the end cap, and the rubber ring 142 is engaged with the end side of the installation groove body 10. The installation groove body 10 is sealed with the end cap 14 through the rubber ring 142. A rubber groove 143 is also provided on the end cap 14, and the end cap 14 is engaged with the rubber ring 142 through the rubber groove 143. A circle of raised "blade edges 141" is provided on the inner side of the rubber groove 143. A rubber ring 142 is provided in the rubber groove 143 to seal the side of the installation groove body 10. The relative position of the rubber ring 142 and the combined assembly part is controlled by precise positioning to ensure that the rubber ring 141 is compressed and sealed according to the designed position. The rubber ring 142 is designed with a large compression amount to effectively fill the gap caused by the assembly error. Furthermore, in the key sealing loop, a circle of raised “edges 141” is added outside the rubber groove 143 to increase the sealing pressure while keeping the clamping force unchanged, thereby increasing the reliability of the end face seal.

[0035] Furthermore, the left and right side surfaces of the installation slot body match the outer edges of the end cover, and the outer edges of the end cover are provided with multiple groups of threaded holes matching the screws.

[0036] Furthermore, if Figure 4As shown, both sides of the mounting groove 10 are provided with evenly distributed "tooth"-shaped screw mounting holes, that is, the self-tapping screw holes on the mounting groove 10 are installed in an evenly distributed tooth shape 13. This design helps to balance the radial force of the screw, and the radial force is evenly applied when the screw is screwed in without tilting.

[0037] Furthermore, an arched mounting hole 31 is provided in the middle of the multi-directional adjustable bracket 30 for adjusting the angle; a pair of waist-shaped mounting holes 32 are provided at the bottom of the multi-directional adjustable bracket 30 for adjusting the height. Bolts and nuts pass through the mounting holes and are fixedly connected to the mounting frame of the mounting slot 10. The design of the multi-directional adjustable bracket 30 enables the product to have angle and height adjustment functions, and is suitable for tunnel top installation and side wall installation.

[0038] In this embodiment, the multi-color lighting lamp group is installed on the lamp bead substrate 12, and the multi-color lighting lamp group includes a white light lighting lamp group and an RGB lighting lamp group. Both the white light lighting lamp group and the RGB lighting lamp group are provided with a waterproof device.

[0039] Specifically, as shown in the figure, in this embodiment, the white light lighting lamp group is designed as a rectangular plate, and rectangular RGB lighting lamp groups are respectively provided adjacent to each other on both sides of the white light lighting lamp group. The maximum light intensity angle and the light intensity above 80° in the driving direction are strictly controlled for white light lighting, and the RGB lighting lamp group adopts a small-angle focusing in the driving direction. The lamp groups all adopt professional lighting design: the maximum light intensity angle and the light intensity above 80° in the driving direction are strictly controlled for white light lighting; the red, yellow and green lights use small-angle annular lighting, and the driving direction uses small-angle focusing, which effectively suppresses the impact of glare on driving and helps to highlight the color under white light lighting. The tunnel radial direction (perpendicular to the lane direction) adopts a large-angle lighting distribution to form a clearly discernible light closed loop on the entire tunnel annular (rectangular, trapezoidal, etc.) wall.

[0040] Furthermore, the waterproof device includes a glass lampshade and a packaging colloid. The packaging colloid is provided on the inner and outer sides of the bottom surface of the glass lampshade, and the luminous surface of the glass lampshade adopts a hidden double-layer waterproof seal. The glass lampshade has two layers of sealing strips, double protection, and effectively prevents external water pressure invasion.

[0041] In this embodiment, the control device 20 includes a decoding drive controller, which includes a single-chip microcomputer and a communication device for receiving lighting status control instructions; the white light lighting group is connected to the first control end of the decoding drive controller, and the RGB lighting group is connected to the second control end of the decoding drive controller.

[0042] Specifically, the white light lighting group provides basic lighting and enhanced lighting for the tunnel; the RGB lighting group is a red, green and yellow three-color lighting distribution system. The red, yellow and green colors are defined like the traffic lights on the road, red light "stop", green light "go", and yellow light "slow passage". The RGB lighting group has modes such as red light always on, yellow light flashing, and green light jumping. When the tunnel is congested and the vehicle is stagnant, the red light is always on. The constant light can be displayed when the tunnel state is constant and has not changed. At this time, the lamps and lanterns will produce red spots on the inner contour of the tunnel, making the tunnel red. The rear vehicles are clearly visible, and safety measures such as early deceleration, braking, and maintaining a reasonable distance can be taken; when the yellow light flashes, it means slow passage, and the flashing frequency can be adjusted (similar to the process of traffic light transformation). The closer to the congestion state, the higher the flashing frequency, and the color depth can also change gradually from light to dark; green represents passage. According to the appropriate passage speed of the tunnel, the green light jumps at the same frequency to guide the vehicle to control the speed and pass through the tunnel quickly and safely. The decoding drive controller enables the white light lighting group and the RGB lighting group to work independently. When the first control end controls the ordinary lighting of the white light lighting group to be in a constant light state, the second control end works in coordination to coordinate the dimming and color adjustment of the RGB lighting group and control the working modes of the red, green and yellow lights.

[0043] Furthermore, the control device 20 also includes a tunnel monitoring control system, and the decoding drive controller is connected to the tunnel monitoring control system via a communication device, and the communication device adopts a wireless communication method or a wired communication method. The decoding drive control device 20 is connected to the tunnel monitoring control system, receives a feedback signal from the system end, and executes a corresponding lighting rule.

[0044] In summary, the technical solution of this application has the following beneficial effects:

[0045] 1. The utility model provides a multi-purpose LED tunnel lighting device. The device integrates white light lighting and traffic lights to guide safe driving.

It is highly practical.

[0046] 2. The utility model adopts a multi-directional adjustable mounting bracket. The bracket design enables the lighting device to have angle and height adjustment functions, which is suitable for various installation adjustment needs such as tunnel top mounting and side wall mounting.

[0047] 3. The lighting device of the utility model adopts an integrally formed installation slot and adopts full structural sealing, which avoids various difficulties in production process, quality and control of gluing and sealing. At the same time, the upper and lower hidden double-layer O-shaped rubber strips are used for sealing protection in the base plate slot for installing the lamp group, which improves reliability while ensuring the overall structural aesthetics.

[0048] 4. Through the provision of end covers, rubber rings and multiple groups of bolts, when fixing the end covers, multiple groups of screws are used to fix the end covers, and the rubber rings can well seal the installation slots to prevent external moisture from entering the lamps.
