Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to a long light bar connection component for a bridge guardrail. Background Art

[0002] Bridge railing lights typically refer to lamps installed on bridge railings or guardrails. They utilize the steel pipes of the bridge's guardrails as a carrier, meeting the dual needs of bridge deck protection and illumination while avoiding the light pollution caused by high-pole streetlights. These lights are typically designed in an elongated strip, suitable for installation on structures like guardrails and railings, serving both lighting and decorative purposes.

[0003] Generally, the light strips used in guardrail lights are relatively long. Due to the traffic demand of modern bridge decks, the bridge deck guardrails are in a shaking state for a long time. The existing light strip fixing method is to fix it with conventional screws. Under long-term shaking, the connection between the screws and the light strip and the light guide plate (which tilts the light beam downward to prevent glare) will be deformed, resulting in an unstable connection between the light strip and the circuit board, a high failure rate, and the need for regular maintenance, which affects maintenance costs and also causes inconvenience in bridge deck lighting.

[0004] Therefore, it is necessary to further improve the light bar connection structure of the bridge guardrail light to solve the above-mentioned problem of poor connection strength. Utility Model Content

The clamping slot is adapted to the shape of the clamping block. The two sides of the connecting plate are respectively located on the corresponding connecting arm.

[0009] The circuit board is connected to the positioning block via the fastening screws;

[0010] The light bar assembly includes an aluminum substrate and a light guide plate, the aluminum substrate is provided with a positioning hole and a fixing hole, the top screw passes through the positioning hole to position the aluminum substrate above the connecting plate; the light guide plate is provided with a fastening port, the fastening screw passes through the fastening port, the fixing hole, and the mounting hole in sequence to connect the light guide plate above the aluminum substrate, and the aluminum substrate is located between the positioning block and the light guide plate.

[0023] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-3 As shown, the utility model is a bridge guardrail long light bar connection assembly, including a lamp holder 1, a circuit board 2, a light bar assembly 3, and a plurality of positioning blocks 4. The circuit board 2 and the light bar assembly 3 are connected to the lamp holder 1 through the positioning blocks 4;

[0025] A slot 12 is provided in the middle of the lamp holder 1, and connecting arms 11 extend outwards from both sides of the slot 12;

[0026] like Figure 4 As shown, the positioning block 4 includes a top screw 41, a fastening screw 42, a connecting plate 43, and a clamping block 44. The connecting plate 43 is provided with a mounting hole 45 and a top screw hole 46. The top screw 41 passes through the top screw hole 46 and abuts against the connecting arm 11. The clamping block 44 is clamped in the clamping groove 12. The clamping groove 12 is adapted to the shape of the clamping block 44. The two sides of the connecting plate 43 are respectively located on the corresponding connecting arm 11.

[0027] The circuit board 2 is connected to the positioning block 4 by fastening screws 42;

[0028] The connecting plate 43 is provided with a mounting hole positioning groove 431 and a top screw hole positioning groove 432 . The center of the mounting hole 45 is located on the mounting hole positioning groove 431 , and the center of the top screw hole 46 is located on the top screw hole positioning groove 432 .

[0029] In order to ensure the connection strength of the guardrail light, the long light strip is provided with multiple connection points, each of which is positioned by a positioning block 4. When fixing each connection point, any slight deviation in the opening of the mounting hole 45 and the top screw hole 46 will affect the subsequent fixed position of each connection point, and may even cause some connection points to be misaligned with the positioning block 4, requiring re-alignment, which affects assembly efficiency. The mounting hole positioning groove 431 can locate the opening position of the mounting hole 45, and the top screw hole positioning groove 432 can locate the opening position of the top screw hole 46, preventing the center points of the mounting hole 45 and the top screw hole 46 from deviating from the target connection center point, reducing the position deviation of each connection point of the long light strip, and improving assembly efficiency.

[0030] like Figure 5-6 As shown, the light bar assembly 3 includes an aluminum substrate 31 and a light guide plate 32. The aluminum substrate 31 is provided with a positioning hole 311 and a fixing hole 312. The top screw 41 passes through the positioning hole 311 to position the aluminum substrate 31 above the connecting plate 43; the light guide plate 32 is provided with a fastening opening 321. The fastening screw 42 passes through the fastening opening 321, the fixing hole 312, and the mounting hole 45 in sequence to connect the light guide plate 32 to the top of the aluminum substrate 31. The aluminum substrate 31 is located between the positioning block 4 and the light guide plate 32.

[0031] The outer wall of the card block 44 is an arc-shaped structure, and accordingly, the inner wall of the card slot 12 is an arc-shaped structure. Compared with the conventional planar structure, the arc-shaped inner wall of the card slot 12 can more tightly wrap the arc-shaped card block 44 stuck therein, and when the bridge guardrail continues to shake, it plays a certain buffering and shock-resistant role, strengthens the connection strength of the positioning block 4, and further reduces the loosening of the circuit board 2 and the light bar assembly 3.

[0032] The clamping block 44 is provided with a seismic through-groove 441, which keeps the wall thickness of the clamping block 44 and the thickness of the connecting plate 43 basically consistent, ensuring that the overall force of the positioning block 4 remains relatively balanced, improving the connection stability of the positioning block 4, and when the lamp holder 1 shakes, it plays a seismic buffering role for the connected circuit board 2 and light bar assembly 3.

[0033] Because the light bar used in the guardrail light is long, when assembling the light bar assembly 3, due to the size error of the fastening openings 321, some fastening openings 321 may be misaligned with the fixing holes 312, requiring readjustment, which affects installation efficiency. The fastening openings 321 are preferably fastening slots. Compared to conventional hole structures, the fastening slot structure provides space for positioning during installation of the light guide plate 32, allowing for flexible fixation of the fastening screws 42.

[0034] The preferred embodiments of the present invention have been specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all within the scope defined by the claims of this application.
