Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to an LED linear floodlight. Background Technology

[0002] LED linear floodlights are luminaires that achieve a uniform floodlight effect through linearly arranged LED light sources. They combine a sense of line with soft lighting characteristics, offering advantages such as uniform light distribution, no obvious glare, and flexible installation, making them suitable for large-area lighting needs. LED linear floodlights are commonly used in outdoor landscape lighting scenarios.

[0003] Existing LED linear floodlights are installed on the exterior walls of buildings to provide decorative lighting at night and enhance the aesthetics of the building facades. However, due to their long-term outdoor installation, the outer surface of the light-transmitting panels of these LED linear floodlights accumulates a significant amount of dust and stains. Furthermore, because they are typically installed at a high position, manual cleaning is difficult, and the dust and stains adhering to the light-transmitting panels severely affect their lighting performance. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide an LED linear floodlight.

[0005] The purpose of this utility model is achieved through the following technical solution: an LED linear floodlight, including a lamp body, a cleaning module provided on the lamp body, the cleaning module including a guide frame, a sliding body provided in the guide frame, a cavity provided in the sliding body, a plurality of nozzles provided on one side of the sliding body, and a first interface provided on the sliding body; a pushing device is provided between the sliding body and the guide frame, and a second interface is provided on the pushing device, the first interface and the second interface are connected to a water pipe, and the water pipe is connected to a water supply device;

[0006] When the cleaning module is in the cleaning state, the pusher device drives the sliding body to the extended state under the action of water pressure, and the nozzle is located in front of the light-transmitting plate on the lamp body; when the cleaning module is in the non-cleaning state, the sliding body is in the retracted state, and the nozzle is located behind the light-transmitting plate on the lamp body.

[0007] Preferably, the pushing device includes a piston cylinder, a piston is disposed inside the piston cylinder, a pressure chamber is formed between the piston and one end of the piston cylinder, and a second interface is connected to the pressure chamber; a spring is disposed between the piston and the other end of the piston cylinder; a push rod is disposed on the piston and is connected to the sliding body.

[0008] Preferably, the first and second interfaces are connected to the water pipes via a liquid separation component.

[0009] Preferably, the liquid separating component is provided with an inlet, a first outlet, and a second outlet.

[0011] Preferably, the guide frame is provided with connecting plates at both ends, and the connecting plates are connected to the lamp body by connecting screws.

[0012] Preferably, the nozzle is a fan-shaped nozzle.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model effectively solves the industry pain points of dust accumulation on the light-transmitting panels of outdoor lighting fixtures affecting lighting effects and the difficulty of manual cleaning by integrating a retractable automated cleaning module into the LED linear floodlight. During cleaning, the water supply device delivers clean water or cleaning fluid at a certain pressure to the cleaning module through a water pipe. Some of the liquid goes to the pushing device, which uses water pressure to push the sliding body, causing it to move to the extended state, and moving the nozzle to the front of the light-transmitting panel. When the nozzle moves to the front of the light-transmitting panel, the liquid (clean water or cleaning fluid) in the water pipe is sprayed out through the nozzle. The sprayed liquid directly washes away the dust and stains on the outer surface of the light-transmitting panel, thereby achieving a cleaning effect on the surface of the light-transmitting panel. There is no need for manual climbing to high altitudes, avoiding the problems of light scattering and brightness attenuation caused by dust accumulation, and continuously maintaining the light transmittance and lighting effect of the lighting fixture.

[0015] 2. When the cleaning module is not in the cleaning state, the sliding body retracts into the guide frame, so that the nozzle is located behind the light-transmitting plate. This can prevent the nozzle from blocking the light emitted by the LED linear floodlight and prevent the presence of the nozzle from affecting the lighting effect of the LED linear floodlight.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0025] like Figures 1 to 7 As shown, an LED linear floodlight includes a lamp body 1, a cleaning module on the lamp body 1, the cleaning module including a guide frame 2, a sliding body 3 in the guide frame 2, a cavity inside the sliding body 3, a plurality of nozzles 4 on one side of the sliding body 3, and a first interface 3-1 on the sliding body 3; a pushing device 6 is provided between the sliding body 3 and the guide frame 2, and a second interface 6-2 is provided on the pushing device 6; the first interface 3-1 and the second interface 6-2 are connected to a water pipe, and the water pipe is connected to a water supply device;

[0026] When the cleaning module is in the cleaning state, the pushing device 6 drives the sliding body 3 to move to the extended state under the action of water pressure, and the nozzle 4 is located in front of the light-transmitting plate 1-1 on the lamp body 1; when the cleaning module is in the non-cleaning state, the sliding body 3 is in the retracted state, and the nozzle 4 is located behind the light-transmitting plate 1-1 on the lamp body 1.

[0027] This invention effectively solves the industry pain point of dust accumulation on the light-transmitting plate of outdoor lighting fixtures affecting the lighting effect and the difficulty of manual cleaning by integrating a retractable automated cleaning module into the LED linear floodlight.

[0028] The cleaning module uses water pressure to drive the pusher 6, causing the sliding body 3 to move the nozzle 4 between the "extended state" (during cleaning) and the "retracted state" (when not cleaning). During cleaning, the cleaning water supply device delivers clean water or cleaning fluid at a certain pressure to the cleaning module through water pipes. Some of the liquid flows to the pusher 6, which uses water pressure to push the sliding body 3, causing it to move to the extended state and move the nozzle 4 to the front of the light-transmitting plate 1-1. When the nozzle 4 moves to the front of the light-transmitting plate 1-1, the liquid (clean water or cleaning fluid) in the water pipes is sprayed out through the nozzle 4. The sprayed liquid directly washes away the dust and stains on the outer surface of the light-transmitting plate 1-1, thus achieving a cleaning effect on the surface of the light-transmitting plate 1-1. This eliminates the need for manual climbing to heights, avoids light scattering and brightness attenuation caused by dust accumulation, and continuously maintains the light transmittance and lighting effect of the lamps.

[0029] Multiple nozzles 4 are set on one side of the sliding body 3, which can form a dense spray area to cover the entire surface of the light-transmitting plate 1-1. Combined with water pressure, it can achieve cleaning without dead angles, and the cleaning efficiency is significantly higher than the traditional manual wiping method.

[0030] When the cleaning module is not in the cleaning state, the sliding body 3 retracts into the guide frame 2, so that the nozzle 4 is located behind the light-transmitting plate 1-1. This can prevent the nozzle 4 from blocking the light emitted by the LED linear floodlight and prevent the presence of the nozzle 4 from affecting the lighting effect of the LED linear floodlight.

[0031] The pushing device 6 relies on the water pressure in the water pipe to extend and retract the sliding body 3, eliminating the need for an additional electric drive motor or complex transmission mechanism, thus reducing the structural complexity and manufacturing cost of the cleaning module.

[0032] The guide frame 2 is provided with a sliding cavity that matches the slider 3. The guide frame 2 is open on the side facing the light-transmitting plate 1-1, and the slider 3 is set in the sliding cavity.

[0033] The pushing device 6 includes a piston cylinder 6-1, inside which a piston 6-3 is installed. A pressure chamber is formed between the piston 6-3 and one end of the piston cylinder 6-1, and a second interface 6-2 communicates with the pressure chamber. A spring 6-5 is installed between the piston 6-3 and the other end of the piston cylinder 6-1. A push rod 6-4 is installed on the piston 6-3 and is connected to the sliding body 3. The pushing device 6 adopts a mechanical structure design of "piston cylinder 6-1 + spring 6-5 + push rod 6-4", and the extension and retraction control of the sliding body 3 is achieved through the dynamic balance of water pressure and the elastic force of spring 6-5. In the non-cleaning state, the water pipe stops supplying water to the pushing device 6. At this time, the sliding body 3 is in the retracted state under the action of spring 6-5. In the cleaning state, the water pipe supplies water to the pushing device 6, and water enters the pressure chamber. Under the action of water pressure, the piston 6-3 moves against the spring 6-5, thereby pushing the sliding body 3 to the extended state.

[0034] The first interface 3-1 and the second interface 6-2 are connected to the water pipe through the liquid separation component 5. Specifically, the liquid separation component 5 is provided with an inlet 5-1, a first outlet 5-1, and a second outlet 5-2. The inlet 5-1 is connected to one end of the water pipe, the first outlet 5-1 is connected to the first interface 3-1 through a flexible tube, and the second outlet 5-2 is connected to the second interface 6-2 through a flexible tube.

[0035] The guide frame 2 has connecting plates 2-1 at both ends, and the connecting plates 2-1 are connected to the lamp body 1 by connecting screws 7. The connection between the guide frame 2 and the lamp body 1 by connecting screws 7 facilitates the installation and disassembly of the cleaning module, allowing the cleaning module to be flexibly installed according to actual needs.

[0036] In this embodiment, the nozzle 4 is a fan-shaped nozzle 4. The spray area of ​​the fan-shaped nozzle 4 is fan-shaped, and a single nozzle 4 can cover a large cleaning area. This utility model has five nozzles 4 evenly arranged along the length of the wall washer light body, and the five nozzles 4 can fully cover the entire outer surface of the light-transmitting panel 1-1.

[0037] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
