[0002] At present, most LED guardrail lamps on the market adopt embedded installation solutions (i.e., the lamps are embedded in the guardrail). This installation method requires cutting the through slots for installing lamps on the guardrail in advance, which is cumbersome and costly. If the guardrail that has been installed on the road and originally had no lamps installed is to be retrofitted with lights, the original guardrail needs to be dismantled and replaced with a guardrail with a through slot for installing lamps, which is cumbersome and increases a lot of labor and costs.

[0003] Since the number of highway lanes and guardrail heights in the installation environment vary, the requirements for the light output angle of the lamps are also different. The embedded installation products currently on the market require the entire installation guardrail to be rotated to adjust the light output angle of the lamp. Since the installation guardrail is large and heavy, it is time-consuming and laborious to rotate. In addition, there is no corresponding reference when adjusting the angle of the embedded installation product, and it is impossible to accurately adjust the light output angle of the lamp. The adjustment is time-consuming and laborious. If the rotation angles of the continuously installed lamps are very different, it will also affect the lighting effect of the road.

[0030] like Figures 1 to 4 As shown, the utility model is a surface-mounted guardrail lamp with precise angle adjustment. When in use, it is installed on the guardrail 50. Its structure includes a lamp body 10, and a light source module and a light guide plate 20 are installed on one side of the lamp body 10. A light blocking plate 30 is arranged on the outer side of the light guide plate 20. A V-shaped angle is formed between the light blocking plate 30 and the light source module, which can meet the requirements of on-site light parameters and can be installed in time with different numbers of lanes and different heights of guardrails 50. It can effectively prevent glare, avoid the interference of glare on pedestrians and vehicles, ensure traffic safety, and effectively prevent light pollution.

[0031] The two ends of the lamp body 10 in the length direction are respectively covered with end caps 40. It can be understood that the light source module includes a high-performance light-emitting diode, a substrate, and electronic components, and the light source module is installed on the side mounting plate of the lamp body 10.

[0032] The end cap 40 is provided with an end cap toothed portion, which meshes with the movable bracket toothed portion of the bracket assembly, and the spacing between the movable bracket toothed portion and the end cap toothed portion can be adjusted to achieve rotation adjustment of the lamp body 10. During adjustment, the movable bracket toothed portion and the end cap toothed portion are disengaged, so that the lamp body 10 can be rotated to a suitable light-emitting angle, and then the end cap toothed portion and the movable bracket toothed portion are kept in meshing state, and the lamp body 10 with the adjusted angle is locked and fixed.

[0033] Furthermore, in order to ensure that the bracket assembly can remain fixed relative to the guardrail 50 when the lamp body 10 is rotated and adjusted, the bracket assembly is locked to the guardrail 50 through the clamp 60. In order to ensure that the bracket assembly and the guardrail 50 are locked, the position can be stable and secure, and an anti-skid silicone pad 47 is provided between the bracket assembly and the guardrail 50 to enhance the damping effect between the lamp and the guardrail 50, and prevent the lamp from being offset in the installation angle due to the vibration generated by the vehicle during the road driving. The two ends of the lamp body 10, the light guide plate 20 and the light baffle 30 are respectively clamped in the corresponding positioning grooves of the end cover 40, so as to achieve the limit fixation of the two ends of the lamp body 10, the light guide plate 20 and the light baffle 30. A V-shaped groove is formed between the light guide plate 20 and the light baffle 30.

[0034] like Figure 3 , 4 As shown, in order to achieve accurate angle adjustment of the lamp body 10, the end cap 40 is fastened with a dial 41 to display the rotation angle of the lamp body 10. Thus, the lamp body 10 can be accurately rotated to a suitable light-emitting angle, and the corresponding dial scale can be recorded. Finally, other lamps can be adjusted to the same angle according to this scale to ensure the consistency of the light-emitting angles of all lamps in the installation environment.

[0035] A level 42 is also installed on the end cover 40. During the adjustment process, the lamp body 10 is set to the initial installation state when the level 42 is horizontal. When the angle needs to be adjusted, the angle can be adjusted by rotating the lamp without loosening the clamp 60. (First loosen the first screw 45 and the second screw 46 of the fixed bracket 44 and the movable bracket 43, then the lamp can be rotated to adjust the angle. When it is adjusted to a suitable angle, tighten the screws to lock the angle of the lamp). By adjusting the angle of the lamp, it can meet the installation and use of different guardrail 50 heights and different lanes, and can meet the lighting requirements.

[0036] Further, the bracket assembly includes a movable bracket 43 and a fixed bracket 44. The hoop 60 is locked on the fixed bracket 44, and the hoop 60 is limited by the bending limit portion constructed on the upper end of the fixed bracket 44.

The bottom surface of the movable bracket 43 is configured with a movable bracket toothed portion, and the upper surface of the movable bracket 43 is configured with an integrally connected guide portion 43 - 1 .

[0038] Furthermore, in order to enable the movable bracket 43 to be reliably and smoothly guided to move relative to the fixed bracket 44, the fixed bracket 44 is provided with a limit groove, and the guide part 43-1 is cooperatively arranged in the limit groove to realize the connection between the movable bracket 43 and the fixed bracket 44, and to ensure that the movable bracket 43 can be reliably guided to move relative to the fixed bracket 44.

[0039] The second screw 46 is threadedly connected to the fixed bracket 44, and the lower end of the second screw 46 extends into the limiting groove and is pressed against the upper end of the guide portion 43-1 to ensure that the toothed portion of the movable bracket is meshed with the toothed portion of the end cover.

[0040] In order to achieve a reliable connection between the movable bracket 43 and the fixed bracket 44, a third screw 48 is also threadedly connected to the fixed bracket 44, and the third screw 48 supports the bottom surface of the guide part 43-1, so that the upper and lower ends of the guide part 43-1 are limited and fixed, thereby achieving a reliable connection between the movable bracket 43 and the fixed bracket 44.

[0041] In order to ensure that the movable bracket 43 can reliably and stably move relative to the fixed bracket 44, the fixed bracket 44 is provided with a positioning groove, and both sides of the guide portion 43-1 are limited by the positioning groove.

[0042] The movable bracket 43 is constructed in the shape of a paper clip, and the bottom step of the movable bracket 43 is supported on the screw connection column constructed on the outer surface of the end cover 40. The first screw 45 passes through the center hole of the movable bracket 43 and is fastened to the screw connection column to fix the movable bracket 43 to the end cover 40. The movable bracket 43 is supported and positioned by the screw connection column and the toothed portion of the end cover, and the positioning is stable.

[0043] In practice, in order to better protect both ends of the light shielding plate 30 and prevent them from being eroded by rain due to exposure to air, the light shielding plate 30 extends to the corresponding mounting groove of the end cover 40. The light guide plate 30 is made of high-transmittance and high-strength tempered glass.

[0044] The other side of the lamp body 10 is an open end, and the bottom plate 11 or the wire groove 12 is respectively clamped in the clamping grooves constructed on both sides of the open end. When the bottom plate 11 is used, it is the first embodiment of the present application; when the wire groove 12 is used, it is the second embodiment of the present application.

[0045] When the wire trough 12 is installed, the axial extension length of the wire trough 12 is greater than the length of the lamp body 10, and the wire trough cover 13 is fastened on the trough body where the wire trough 12 extends to the outside of the lamp body 10. The wire trough 12 can hide the lamp power cord and on-site construction wires inside the wire trough 12, and no wires are exposed to the installation environment, which is safe and beautiful; at the same time, it realizes seamless splicing between lamps. (Installation of the wire trough 12: After the lamp is fixed on the guardrail 50, insert the wire trough 12 from the bottom of the lamp, then place the lamp power cord inside the wire trough 12, and finally fix the wire trough cover 13 on the wire trough 12 with screws.)
