Description

Technical Field

[0001] The utility model relates to the technical field of lighting devices, in particular to a bridge guardrail lamp housing which is easy to install. Background Art

[0002] Bridge railing lights utilize the steel pipes of the bridge's guardrails as a carrier for the lamps, meeting the dual needs of bridge deck protection and illumination while avoiding the light pollution caused by high-pole streetlights. Typically designed in an elongated strip, they are suitable for installation on structures such as guardrails and railings, serving both lighting and decorative purposes. Bridge railing lights are typically installed at a height of 1 to 1.5 meters. The illumination angle of the lamps is tilted downward, focusing the light on the road surface and preventing light pollution. Furthermore, optical principles are used to suppress the angle of the light beam, reducing glare.

[0003] Guardrail lights are typically fixed to bridge railings using pre-buried screws and brackets. However, due to the constant vibration of the bridge's guardrails caused by traffic, the screws can become loose, putting the guardrail lights at risk of falling off. Furthermore, during installation, the installation location of guardrail lights can vary depending on the distribution of the bridge railings, with some requiring installation on the side and others on the bottom. This requires prefabricating multiple mounting housings to maintain a downward angle, and then selecting different housings at the installation site based on the installation requirements to accommodate a variety of mounting locations. This existing housing structure increases production costs and impacts the efficiency of guardrail light assembly and installation.

[0004] Therefore, it is necessary to further improve the shell structure of the bridge guardrail lamp to solve the above-mentioned problems of low installation efficiency and strength. Utility Model Content

[0005] The purpose of the utility model is to provide a bridge guardrail lamp housing that is easy to install, which can realize the rapid assembly and installation of the bridge guardrail lamp.

[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 As shown, the utility model is a conveniently installed bridge guardrail lamp housing, comprising a lamp stand 1, a lamp shade 2, and two fixing frames 3, the two fixing frames 3 being respectively located at both ends of the lamp stand 1 and the lamp shade 2;

[0025] like Figure 2 As shown, the lamp stand 1 is an equilateral "L" shape. The top edge of the lamp stand 1 is provided with a lighting groove 11 and a lighting fillet 12 to meet the lighting angle of the bridge railing. The light from the lighting groove 11 is emitted at a 45° angle to avoid glare to drivers on the bridge and affect driving safety. The lamp stand 1 is provided with a clamping edge 13 on both sides.

[0026] like Figure 3 As shown, the lampshade 2 is "C"-shaped, and the top edge of the lampshade 2 is provided with a fool-proof rounded corner 12; the end of the long side 21 of the lampshade 2 is provided with a long side slot 22, and the end of the short side 23 of the lampshade 2 is perpendicularly provided with a short side extension 24, and the end of the short side extension 24 is provided with a short side slot 25; the shapes of the long side slot 22 and the short side slot 25 are adapted to the card edge 13, and one card edge 13 is snapped into the long side slot 22, and the other card edge 13 is snapped into the short side slot 25;

[0027] The card edge 13 is preferably an arc-shaped structure. Compared with the card edge 13 with a right-angle structure, the card edge 13 with an arc-shaped structure is easier to slide into the long side card slot 22 or the short side card slot 25 during assembly, which is convenient for manual operation.

[0028] like Figure 4 As shown, the inner wall of the fixing frame 3 is distributed with reinforcing ribs 32, and the reinforcing ribs 32 are located on the outer walls of the lamp holder 1 and the lamp shade 2; the reinforcing ribs 32 not only strengthen the structural strength of the fixing frame 3, but also increase the gap between the fixing frame 3 and the outer walls of the lamp holder 1 and the lamp shade 2. Compared with the close fit between the fixing frame 3 and the outer walls of the lamp holder 1 and the lamp shade 2, the reinforcing ribs 32 provide a buffer space to avoid the problem of difficulty in disassembling and assembling the fixing frame 3 due to the expansion of the lamp holder 1 and the lamp shade 2 due to temperature changes.

[0029] A mounting part 34 is provided on one side of the fixed frame 3, and two opposite sides of the fixed frame 3 are provided with mounting fillets 31 that are compatible with the lighting fillet 12 and the anti-fool fillet 12, which play an anti-fool effect during the assembly process, reduce operator errors, and improve assembly efficiency.

[0030] When the lamp housing is installed on the railing, according to the distribution position and setting shape of the bridge railing, in order to ensure that the lighting groove 11 of the lamp holder 1 is always tilted downward toward the road surface, it is only necessary to flexibly adjust the assembly position of the lampshade 2 to meet the installation requirements. There is no need to prefabricate the fixing frames 3 with different installation surfaces, saving installation time and production costs.

[0031] In this embodiment, the cross section of the fixing frame 3 is rectangular, and the mounting member 34 is located on the short side of the fixing frame 3. There are two geometric transformation installation methods:

[0032] Method 1: If Figure 5 As shown, when the lamp housing needs to be installed under the railing, the short side slot 25 of the short side extension 24 is clamped on the upper clamping edge 13 of the lamp holder 1, and the long side slot 22 of the long side 21 is clamped on the lower clamping edge 13 of the lamp holder 1. The mounting piece 34 on the short side of the fixing frame 3 faces upward, and it can be installed under the railing.

[0033] Method 2: If Figure 6 As shown, when the lamp housing needs to be installed on the side of the railing, the short side slot 25 of the short side extension 24 is clamped on the lower clamping edge 13 of the lamp holder 1, and the long side slot 22 of the long side 21 is clamped on the upper clamping edge 13 of the lamp holder 1. The mounting piece 34 located on the short side of the fixing frame 3 faces sideways and can be installed on the side of the railing.

[0034] The utility model provides a bridge guardrail lamp housing which is easy to install. A lighting component is set on the top edge of the lamp holder 1, so that the lighting component emits light source obliquely downward at the lighting fillet 12. The two clamping edges 13 of the lamp holder 1 are connected to the lamp shade 2 through the long side clamping groove 22 and the short side clamping groove 25 of the lamp shade 2 to assemble into a square lamp housing structure; the fixing frame 3 is inserted into the end of the square lamp housing. When installing the lamp housing on the bridge railing, it is only necessary to connect the fixing frames 3 at both ends to the railing through the mounting parts 34 to complete the quick installation of the lamp housing.

[0035] The fixing frame 3 is provided with a fixing hole 33. After the fixing frame 3 is put on the end of the assembled square lamp shell, the top screw (an existing part, not shown in the figure) is pressed against the lampshade 2 or the lamp holder 1 through the fixing hole 33, thereby strengthening the connection strength of the fixing frame 3 and reducing the looseness of the fixing frame 3.

[0036] The mounting member 34 is provided with a convex mounting groove 341. In view of the frequent shaking of the bridge railing, the convex mounting groove 34 can be more stably stuck on the bridge railing in combination with the existing fasteners to prevent the lamp housing from falling off.

[0037] 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.
