Description

Technical Field

[0001] This utility model relates to the field of LED street light technology, and in particular to an LED street light with a lightning protection structure. Background Technology

[0002] LED streetlights are high-efficiency and energy-saving lighting devices that use light-emitting diodes as the light source, and are widely used in outdoor lighting applications such as city streets, highways, parks, and residential areas. However, because streetlights are generally tall, they are susceptible to lightning strikes and damage during thunderstorms, thus requiring LED streetlights with lightning protection structures.

[0003] Patent CN111981415A discloses a lightning and rainproof LED street light, belonging to the field of street light technology. It includes a column and an LED light mounted on the column. A rain shield with an inverted "V" shaped cross-section is fixed to the upper end of the column. A solar panel is embedded in the top surface of the rain shield. A long box is fixed to the top of the rain shield, containing a rotating shaft driven by a reversible motor. A shielding cloth, made of insulating material, is wound around the shaft and extends to the outside of the long box to cover the solar panel. A counterweight is connected to the end of the shielding cloth. A lightning rod is fixedly connected to the top of the long box. A control box is fixedly installed on the column. The control box contains a battery electrically connected to the solar panel, LED light, and reversible motor. A condition-activated detector electrically connected to the control circuit of the reversible motor is installed on the LED street light. This patent provides lightning and rain protection for solar panels, offering good protection. While this LED street light is protected by installing a lightning rod, lightning can still strike the LED street light during thunderstorms, damaging its internal circuitry or even causing the entire street light to collapse, thus posing a safety threat to pedestrians and vehicles in the vicinity.

[0004] Based on the above, this utility model proposes an LED street light with good stability and a lightning protection structure. Utility Model Content

Pairs of springs are fixedly connected between the abutments and the limiting rings.

[0007] To further explain, it also includes a support frame and a fixing plate. The support frame is fixedly connected between the outer shell and the rigid rubber rod frame, and the fixing plate is fixedly connected between the outer shell and the support frame.

[0008] Further explanation: It also includes surge protectors, connecting wires, a mounting frame, a baffle, and a cover. A pair of surge protectors are fixed to the housing.

[0010] To further explain, the fixing frame, baffle, and cover are all made of polyethylene to prevent current conduction.

[0011] To further clarify, it also includes warning signs, with warning signs fixed to the fixed frame.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model can provide additional limiting and auxiliary support for the outer shell of the LED street light through components such as rigid rubber poles and abutments, so as to prevent the LED street light from collapsing when it is subjected to severe lightning strikes and posing a safety threat to pedestrians and vehicles in the surrounding area, thereby improving the stability of the LED street light with lightning protection structure.

[0013] 2.

Detailed Implementation

[0022] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0023] Example 1

[0024] An LED street light with a lightning protection structure, such as Figures 1-6 As shown, it includes an outer shell 1, a light strip 2, ground spikes 3, a lightning rod 4, a rigid rubber pole frame 8, a limiting ring 9, a spring 10, and a stop plate 11. The light strip 2 is fixed to the upper right side of the outer shell 1. Four ground spikes 3 are circumferentially distributed and fixed to the bottom of the outer shell 1. The lightning rod 4 is fixed to the top of the outer shell 1. Three wires are longitudinally distributed front and back on the right side inside the outer shell 1. One end of the wire is fixed to the light strip 2, and the other end of the wire is fixed to an external power supply device. The rigid rubber pole frame 8 is fixed to the lower part of the outer shell 1. The middle and upper parts of the rigid rubber pole frame 8 are fixed to the limiting ring 9. The left and right sides of the limiting ring 9 are slidably connected to the stop plate 11. Four springs 10 are fixed between the stop plate 11 and the limiting ring 9.

[0025] like Figure 1 and Figure 5As shown, it also includes a support frame 7 and a fixing plate 12. The support frame 7 is fixedly connected between the outer shell 1 and the lower part of the rigid rubber rod frame 8, and the fixing plate 12 is fixedly connected between the outer shell 1 and the lower part of the support frame 7.

[0026] When installing LED streetlights, the stability of the streetlight housing 1 can be increased by inserting ground spikes 3 into the ground. When lightning strikes the lightning rod 4, the lightning rod 4 will guide the lightning to be released to the ground along a predetermined safe path, reducing the damage of lightning to the streetlight. However, since lightning is usually accompanied by rainfall, and rainfall will make the surface of the housing 1 and the light strip 2 wet, thereby increasing the probability of lightning striking the housing 1 and the light strip 2, when lightning strikes the housing 1, if the lightning intensity is low, the housing 1 will only shake within a certain range. At this time, the abutment plate 11 can dampen the shaking of the housing 1 under the action of the spring 10. The system incorporates shock absorption and vibration reduction to prevent the outer casing 1 from breaking or even collapsing due to excessive shaking. If the lightning strike is strong enough to cause the outer casing 1 to break, components such as the rigid rubber rod 8 and the limiting ring 9 can support and limit the broken outer casing 1, preventing it from collapsing in all directions. The presence of the support frame 7 and the fixing plate 12 can provide additional support to the right side of the rigid rubber rod 8 and the limiting ring 9, thereby effectively preventing the outer casing 1 and the light strip 2 from falling to the right side, i.e., closer to the road surface. This improves the stability of the outer casing 1 and prevents the broken outer casing 1 from posing a safety threat to pedestrians and vehicles on the road.

[0027] Example 2

[0028] Based on Example 1, such as Figure 1 , Figure 3 , Figure 4 and Figure 7 As shown, it also includes a surge protector 5, a connecting wire 6, a fixing frame 13, a baffle 131, and a cover plate 14. Surge protectors 5 are fixedly connected to the upper and lower sides inside the housing 1. The surge protectors 5 are fixedly connected to the wires. A fixing frame 13 is fixedly connected to the lower left side of the housing 1. A connecting wire 6 is fixedly connected to the lower part of the housing 1. One end of the connecting wire 6 is fixedly connected to the adjacent surge protector 5, and the other end of the connecting wire 6 is fixedly connected to the fixing frame 13. A baffle 131 is snapped into the lower left side of the fixing frame 13. A cover plate 14 is rotatably connected to the top of the fixing frame 13.

[0029] like Figure 7 As shown, the top of the fixed frame 13 is provided with a slope to prevent debris from accumulating on the cover plate 14.

[0030] like Figure 7 As shown, the fixing frame 13, baffle 131 and cover plate 14 are all made of polyethylene to prevent current conduction.

[0031] like Figure 7 As shown, it also includes a warning sign 15, which is fixed to the front side of the fixed frame 13.

[0032] When electronic components such as the light strip 2 are struck by lightning, the lightning current will be conducted through the wire to the surge protector 5. The surge protector 5 can absorb and disperse the excessive current, and conduct part of the current to the fixed frame 13 through the connecting wire 6. The excess current and energy are absorbed by the electrolyte solution in the fixed frame 13, thereby preventing the electronic components such as the light strip 2 from being damaged by lightning. When the electrolyte solution needs to be replaced, the baffle 131 can be removed first and the electrolyte solution in the fixed frame 13 can be drained. After the baffle 131 is reinstalled, the cover plate 14 can be opened and new electrolyte solution can be added. The warning sign 15 is used to warn pedestrians to stay away to avoid pedestrians being injured by current conduction.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
