Description

Technical Field

[0001] The invention relates to the technical field of lighting engineering, and in particular to an enveloping LED road and bridge railing lamp. Background Art

[0002] Traditional street lamps usually use light sources such as high-pressure sodium lamps or metal halide lamps. These light sources have problems such as high energy consumption, short life, and low luminous efficiency. In addition, their lighting range is limited and cannot meet the lighting needs of modern roads and bridges. LED light sources have the advantages of low energy consumption, long life, high luminous efficiency, and rich colors. Road and bridge railing lights use LED light sources, which can achieve more flexible and efficient lighting effects through intelligent control. The wraparound design can better concentrate the light of the lamp on the road and bridge, improve the lighting effect, and reduce the scattering and waste of light. The wraparound design can also improve the protection performance of the lamp to prevent the lamp from being damaged by the outside world.

[0003] The specific defects are as follows:

[0004] Firstly, the installation of traditional railing lights requires drilling and fixing operations on the road and bridge railings, and the installation process is relatively cumbersome. For large-scale road and bridge projects, railing lights that are not easy to install require a lot of time and manpower, and drilling and fixing operations on the road and bridge railings will damage the structure of the road and bridge railings. For example, rainwater enters the interior of the road and bridge railings, which leads to corrosion and damage to the railings. Long-term corrosion will weaken the structural strength of the railings, increase safety hazards, and affect the stability of the road and bridge railings. In addition, drilling and fixing operations on the road and bridge railings will affect the appearance of the road and bridge railings, thereby affecting the aesthetics of the road and bridge.

[0005] Secondly, different road and bridge railings have different diameters. Traditional lamps can only adapt to railings of specific diameters, and lamps for railings of different sizes must be customized. Customized lamps require additional design, mold opening and production costs, which will lead to an increase in the price of lamps. Customized lamps are incompatible with other lamps, so the entire lamp system needs to be replaced when replaced, which increases maintenance costs and time. In addition, the installation of lamps cannot meet the needs of railings of different sizes. The mismatch between lamps and railings will lead to unstable installation of lamps. The lamps cannot be firmly fixed on the railings. In bad weather or when impacted by external forces, the lamps are prone to loosening or shaking, which will affect the performance and safety of the lamps.

[0006] Therefore, the present invention proposes an enveloping LED road and bridge railing lamp to make up for and improve the deficiencies of the prior art. Summary of the invention

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0044] refer to Figures 1 to 11According to a preferred embodiment of the present invention, an enveloping LED road bridge railing lamp will be described in detail below. An enveloping LED road bridge railing lamp includes a second lamp 2, a first lamp 1 is rotatably connected to the inside of the second lamp 2, the inside of the first lamp 1 is provided with a mounting mechanism 3 connecting the first lamp 1 and the second lamp 2, the inside of the first lamp 1 and the second lamp 2 are both provided with a positioning mechanism 4 for improving the working efficiency of the fixing mechanism 5, and the inside of the first lamp 1 and the second lamp 2 are both provided with a fixing mechanism 5 for allowing the railing lamp to adapt to road bridge railings of different sizes;

[0045] The mounting mechanism 3 includes a limit block 314 for limiting the rotation of the first lamp 1;

[0046] The positioning mechanism 4 includes a positioning rod 413 that pushes the railing light to the correct fixed position.

[0047] The fixing mechanism 5 includes a clamping block 5110 that fits with the road and bridge railing.

[0048] like Figure 3 , Figure 4 and Figure 5 As shown, Figure 4 In the embodiment, the installation mechanism 3 includes an extension block 311, the extension block 311 is slidably connected to the inside of the first lamp 1 and the second lamp 2, the limit block 314 is rotatably connected to the inside of the second lamp 2, the first spring 312 is fixedly connected to the extension block 311, and a tooth block is arranged on the surface of the extension block 311. The extension block 311 inside the first lamp 1 extends to the inside of the second lamp 2 under manual push. Since the limit block 314 is located inside the sliding path of the extension block 311, the extension block 311 slides and pushes the limit block 314 to rotate. The limit block 314 is located above the tooth block on the surface of the extension block 311. Figure 5 In the embodiment, the interior of the second lamp 2 is fixedly connected with a fixed shaft, and the surface of the fixed shaft inside the second lamp 2 is fixedly connected with a spring paddle 313, and the spring paddle 313 is located above the limit block 314. When the interface of the first lamp 1 and the second lamp 2 overlap, the limit block 314 is pushed by the spring paddle 313 to extend to the inside of the adjacent tooth block on the surface of the extension block 311, thereby limiting the extension block 311. Figure 5In the embodiment, the surface of lamp No. 2 is rotatably connected with a connecting block 316, and a connecting central axis 315 is fixedly connected between the connecting block 316 and the limiting block 314. The interior of lamp No. 1 is fixedly connected with a spring No. 12. By manually turning the connecting block 316, the connecting block 316 rotates and drives the limiting block 314 to rotate through the connecting central axis 315. The connecting block 316 rotates to push the extension block 311 to slide. The spring No. 1 312 is compressed under the push of the extension block 311, and the limiting block 314 is driven by the connecting block 316 to disengage from the adjacent tooth block on the surface of the extension block 311. The limiting block 314 between lamp No. 1 and lamp No. 2 loses the limit of the extension block 311 by the limiting block 314, thereby releasing the connection relationship between lamp No. 1 and lamp No. 2.

[0049] like Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, Figure 7 In the embodiment, the positioning mechanism 4 includes a power push rod 411, which is slidably connected to the interior of the No. 1 lamp 1 and the No. 2 lamp 2, and the interior of the No. 1 lamp 1 and the No. 2 lamp 2 is slidably connected to two connecting push blocks 412, the power push rod 411 is slidably connected to the interior of the connecting push block 412, and a return spring is fixedly connected between the connecting push block 412 and the power push rod 411, and the positioning rod 413 is rotatably connected to the interior of the No. 1 lamp 1 and the No. 2 lamp 2, one end of the positioning rod 413 is rotatably connected to the No. 1 support rod 414, and one end of the positioning rod 413 is rotatably connected to the No. 1 support rod 414, and one end of the No. 1 support rod 414 The second support rod 415 is rotatably connected to the surface of the connecting push block 412. A thrust is manually given to the power push rod 411, and the power push rod 411 slides inside the first lamp 1 and the second lamp 2, and a thrust is given to the connecting push block 412 by the return spring between the power push rod 411 and the connecting push block 412. The connecting push block 412 slides and pulls the first support rod 414 to rotate through the second support rod 415. Since the first support rod 414 rotates coaxially with the positioning rod 413, the first support rod 414 rotates to drive the positioning rod 413 to rotate inside the first lamp 1 and the second lamp 2. Figure 6 In the embodiment, two positioning rods 413 inside the No. 1 lamp 1 and the No. 2 lamp 2 are symmetrically arranged with the power push rod 411 as the axis. The positioning rods 413 inside the No. 1 lamp 1 and the No. 2 lamp 2 are symmetrically arranged. The positioning rods 413 rotate to give a thrust to the surface of the road bridge railing inside the railing lamp, thereby pushing the railing lamp and the road bridge railing to be concentric, so that the position of the road bridge railing is at the center of the railing lamp. By pushing the railing lamp and the center of the road bridge railing, as shown in FIG. Fig. 9 In the figure, a first push rod 416 is fixedly connected to the surface of the power push rod 411 .

[0050] like Fig. 9 , Fig.10 and Fig.11 In Fig. 9 In the embodiment, the fixing mechanism 5 includes a sliding push block 511, and the interiors of the first lamp 1 and the second lamp 2 are both slidably connected with a central push rod 517, and the surface of the central push rod 517 is fixedly connected with a second push rod 5111, and the first push rod 416 on the surface of the power push rod 411 pushes the sliding push block 511 on the surface of the central push rod 517 to slide, thereby giving a thrust to the second push rod 5111 and pushing the central push rod 517 to slide, as shown in FIG. Fig.10 In the embodiment, a sliding push block 511 is slidably connected to the interior of the No. 1 lamp 1 and the No. 2 lamp 2, and the surface of the sliding push block 511 is fixedly connected to two horizontal side blocks 512, and the surfaces of the horizontal side blocks 512 are fixedly connected to guide shafts 514, and the guide shafts 514 are slidably connected to the interior of the No. 1 lamp 1 and the No. 2 lamp 2, and the interiors of the No. 1 lamp 1 and the No. 2 lamp 2 are slidably connected to the limit clamping shaft 519, and the interiors of the No. 1 lamp 1 and the No. 2 lamp 2 are fixedly connected to the No. 4 spring 518, and the No. 4 spring 518 is fixedly connected to the limit clamping shaft 519, and the limit clamping shaft 519 is slidably connected to the interior of the No. 1 lamp 1 and the No. 2 lamp 2. The clamping block 5110 is connected to the interior of the center push rod 517, and the clamping block 5110 is slidably connected to the interior of the No. 1 lamp 1 and the No. 2 lamp 2. The interior of the No. 1 lamp 1 and the No. 2 lamp 2 is rotatably connected with the adjusting dial block 515. The surfaces of the horizontal side block 512 and the center push rod 517 are provided with pulling grooves. Both ends of the adjusting dial block 515 are rotatably connected to the interior of the pulling grooves on the surfaces of the horizontal side block 512 and the center push rod 517. The interior of the No. 1 lamp 1 and the No. 2 lamp 2 is fixedly connected with the No. 2 spring 513. The No. 2 spring 513 is fixedly connected to the horizontal side block 512. The center push rod 517 and A No. 3 spring 516 is fixedly connected between the sliding push block 511. By pushing the sliding push block 511, since the horizontal side block 512 is fixedly connected to the sliding push block 511, the No. 2 spring 513 is compressed, and the horizontal side block 512 is pushed to slide upward by the sliding push block 511. Since the guide shaft 514 is fixedly connected to the horizontal side block 512, the guide shaft 514 slides inside the No. 1 lamp 1 and the No. 2 lamp 2 under the push of the horizontal side block 512, providing a limit for the horizontal side block 512 to prevent the horizontal side block 512 from deviating. The horizontal side block 512 slides upward. Due to the adjustment One end of the shift block 515 is rotatably connected to the inside of the transverse side block 512, and the transverse side block 512 slides upward. The adjusting shift block 515 rotates driven by the transverse side block 512. Since the adjusting shift block 515 is rotatably connected to the inside of the center push rod 517, the adjusting shift block 515 rotates to push the center push rod 517 to slide downward, and the No. 3 spring 516 is compressed under the drive of the center push rod 517, and the clamping block 5110 is driven to detach from the surface of the road and bridge railing through the center push rod 517, and the limit clamping shaft 519 is re-extended to the inside of the center push rod 517 driven by the No. 4 spring 518.

[0051] The following is the entire working process and working principle of the above embodiment:

[0052] Initially: the positioning rod 413 is located inside lamp No. 1 and lamp No. 2, the return spring connecting the push block 412 and the power push rod 411 is in an uncompressed state, the No. 3 spring 516 is in a compressed state, the limit clamp shaft 519 extends to the inside of the center push rod 517, the No. 2 spring 513 is in an uncompressed state, and the clamping block 5110 is located inside lamp No. 1 and lamp No. 2.

[0053] During operation: when the railing light is installed on the road bridge railing, the No. 1 lamp 1 is rotated by manually pushing the extension block 311 inside the No. 1 lamp 1. Under the manual push, the extension block 311 inside the No. 1 lamp 1 extends to the inside of the No. 2 lamp 2. Since the limit block 314 is located inside the sliding path of the extension block 311, the extension block 311 slides and pushes the limit block 314 to rotate. The limit block 314 is located above the tooth block on the surface of the extension block 311. When the interface of the No. 1 lamp 1 and the No. 2 lamp 2 coincide, the limit block 314 extends to the inside of the adjacent tooth block on the surface of the extension block 311 under the push of the spring paddle 313, and then limits the extension block 311, thereby fixing the connection between the No. 1 lamp 1 and the No. 2 lamp 2. When the lamp is damaged and the railing light needs to be disassembled, the connection paddle 316 is manually pushed, the connection paddle 316 rotates and drives the limit block 314 to rotate through the connecting central axis 315. The connecting block 316 rotates to push the extending block 311 to slide, and the No. 1 spring 312 is compressed under the push of the extending block 311, and the limiting block 314 is disengaged from the adjacent tooth block on the surface of the extending block 311 under the drive of the connecting block 316. The limiting block 314 on the extending block 311 between the No. 1 lamp 1 and the No. 2 lamp 2 is lost, thereby releasing the connection relationship between the No. 1 lamp 1 and the No. 2 lamp 2. The limiting state of the extending block 311 inside the No. 1 lamp 1 by the internal limiting block 314 of the No. 2 lamp 2 is used to control the connection state between the No. 1 lamp 1 and the No. 2 lamp 2, thereby solving the problem that the wrap-around LED road and bridge railing lamp is difficult to install and disassemble. The wrap-around design can be quickly installed on the road and bridge railing, greatly improving the installation efficiency, and the railing lamp is easy to install and disassemble, and the position and angle of the lamp can be flexibly adjusted according to actual needs to achieve the best lighting effect.

[0054] Furthermore, when lamp No. 1 and lamp No. 2 are sleeved on the surface of the road bridge railing and the railing lamp needs to be fixed on the surface of the road bridge railing, in order to avoid deviation or tilt during the lamp installation process, a thrust is manually given to the power push rod 411, and the power push rod 411 slides inside the No. 1 and lamp No. 2, and a thrust is given to the connecting push block 412 through the return spring between the power push rod 411 and the connecting push block 412, and the connecting push block 412 slides, thereby pulling the No. 1 support rod 414 to rotate through the No. 2 support rod 415. Since the No. 1 support rod 414 rotates coaxially with the positioning rod 413, the No. 1 support rod 414 rotates, thereby driving the positioning rod 413 to rotate inside the No. 1 and lamp No. 2. The positioning rods 413 inside lamp No. 1 and lamp No. 2 are symmetrically arranged and evenly distributed around the road bridge railing. The positioning rods 413 rotate to give a thrust to the surface of the road bridge railing inside the railing lamp, thereby pushing the railing lamp and the road bridge railing to be concentric, so that the position of the road bridge railing is at the center position of the railing lamp. By pushing the railing lamp and the road bridge railing to the center position, the lamp can be accurately placed in the center position of the railing before the fixing mechanism 5 works, avoiding the installation deviation or tilt of the lamp, thereby ensuring the uniformity and stability of the lighting effect. In addition, center positioning is performed before the fixing mechanism 5 works, so that the contact between the lamp and the railing can be closer and more uniform, reducing the adjustment and correction time of the fixing mechanism 5 and improving work efficiency.

[0055] Furthermore, when the railing lamp and the bridge railing complete the center positioning, by continuously pushing the power push rod 411, the power push rod 411 slides inside the connecting push block 412, so that the No. 1 push rod 416 on the surface of the power push rod 411 pushes the sliding push block 511 on the surface of the center push rod 517 to slide, thereby giving a thrust to the No. 2 push rod 5111 to push the center push rod 517 to slide, the center push rod 517 slides, the limit card shaft 519 slides under the push of the center push rod 517, the No. 4 spring 518 is compressed under the push of the limit card shaft 519, and the center push rod 517 loses the restriction of the limit card shaft 519 and slides under the No. 3 spring The spring 516 slides under the push of the clamping block 5110, and the road bridge railing inside the railing lamp is clamped and fixed by the clamping blocks 5110 on both sides. When the railing lamp needs to be repaired and the connection between the railing lamp and the road bridge railing needs to be released, the sliding push block 511 is pushed. Since the cross side block 512 is fixedly connected to the sliding push block 511, the second spring 513 is compressed, and the cross side block 512 is pushed to slide upward by the sliding push block 511. Since the guide shaft 514 is fixedly connected to the cross side block 512, the guide shaft 514 slides inside the No. 1 lamp 1 and the No. 2 lamp 2 under the push of the cross side block 512. The transverse side block 512 provides a limit to prevent the transverse side block 512 from deviating. The transverse side block 512 slides upward. Since one end of the adjustment block 515 is rotatably connected to the inside of the transverse side block 512, the transverse side block 512 slides upward. The adjustment block 515 rotates under the drive of the transverse side block 512. Since the adjustment block 515 is rotatably connected to the inside of the center push rod 517, the adjustment block 515 rotates to push the center push rod 517 to slide downward. The third spring 516 is compressed under the drive of the center push rod 517, and the clamping block 5110 is driven to separate from the surface of the road and bridge railing through the center push rod 517, and the limit clamping shaft 519 is in the fourth spring 51 8, it re-extends to the inside of the central push rod 517, thereby releasing the clamping state of the clamping blocks 5110 on the bridge railings on both sides, and clamps the bridge railings from both sides by controlling the clamping blocks 5110, thereby realizing the fixation of the railing lamp to the bridge railings of different sizes, solving the problem that traditional lamps cannot meet the needs of bridge railings of different sizes. The fixing mechanism 5 that adapts to different diameters can make the lamp easier to install on railings of different diameters, reducing the installation time and cost, and the fixing mechanism 5 that adapts to different diameters can make the lamp more universal and can be installed on railings of different diameters, thereby improving the versatility and applicability of the lamp.
