Description

Technical Field

[0001] This invention belongs to the field of lamp technology, specifically relating to an LED lamp and its usage method. Background Technology

[0002] An LED light is an electroluminescent semiconductor chip that is fixed to a support using silver or white glue. The chip and circuit board are then connected by silver or gold wires, and the entire circuit is sealed with epoxy resin to protect the internal core wires. Finally, a housing is installed. LED lights have the advantages of energy saving and environmental protection, and have become a major trend in the lighting industry.

[0003] When existing LED lights are used in highly polluted areas, external dust adheres to the surface of the LED light body, obstructing the LED light source. This requires manual cleaning to ensure good lighting performance, which is labor-intensive. Furthermore, the lights are typically installed high up, making cleaning inconvenient and resulting in poor performance. Additionally, if the light body is damaged later in the installation process, the mounting bolts need to be unscrewed, requiring specialized bolting tools, making disassembly time-consuming and laborious. Therefore, we propose an LED light fixture and its usage method. Summary of the Invention

[0004] The purpose of this invention is to provide an LED lamp and its usage method to solve the problems mentioned in the background art, such as the inconvenience of automatically cleaning dirt from the surface of the LED lamp body and the inconvenience of disassembly when replacing the lamp body.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an LED lighting fixture, comprising,

[0006] LED lamp body;

[0007] The drive mechanism is located at the lower end of the front surface of the LED lamp body. It is driven by external natural wind to move the cleaning block on it to clean the surface of the LED lamp body. A rubber scraper is provided on one side of the cleaning block.

[0008] A liquid storage mechanism is fixed on the LED lamp body, and one end of the lower surface of the liquid storage mechanism is provided with an outlet for the internal cleaning liquid to communicate with the interior of the cleaning block, and a seepage hole is provided on one side of the cleaning block.

[0009] Preferably, the driving mechanism includes a driving housing, a fan blade, a driving screw, a moving block, and a connecting rod. The driving housing is disposed at the lower end of the front surface of the LED lamp body. A driving screw is rotatably disposed inside the driving housing, and a fan blade is fixed at one end of the driving screw. The lower end of the cleaning block is connected to the moving block through the connecting rod, and the moving block cooperates with the driving screw through a rack on its lower surface.

[0010] Preferably, the driving mechanism further includes a guide plate, a return spring, a fixing block, a guide protrusion, and a guide groove. The return spring is sleeved on the outside of the connecting rod. The guide plate is fixed to the inside of the driving housing. The front surface of the guide plate is provided with a guide groove. The rear surface of the moving block is provided with a guide protrusion that cooperates with the guide groove to guide the movement. One end of the inner surface of the driving housing is provided with a fixing block that pushes the moving block to move upward.

[0011] Preferably, the fixed block has a right-angled trapezoidal cross-section, and the movable block has a first inclined surface on one side wall that cooperates with the fixed block for guidance.

[0012] Preferably, the driving system further includes a slider and an elastic rubber strip. A groove is provided on the lower surface of the liquid storage mechanism. A slider is slidably disposed inside the groove. An elastic rubber strip is disposed inside the slider. One end of the elastic rubber strip is fixed to the liquid storage mechanism.

[0013] Preferably, a second inclined surface is provided on one side wall of the slider.

[0014] Preferably, the upper inner side of the liquid storage mechanism is provided with a liquid storage chamber, the inner side of the liquid storage chamber is provided with a sealing block, the lower end of the sealing block is provided with a rubber block for sealing the liquid outlet, one side wall of the sealing block is provided with an auxiliary moving block, and the top of the sealing block is provided with a connecting spring for resetting the sealing block.

[0015] An installation structure including an LED lamp body includes a first bracket, a second bracket, a second adjusting screw, and a mounting base. The second bracket is rotatably mounted on both ends of the LED lamp body. A second adjusting screw is provided on one inner end of the second bracket for cooperating with the adjusting hole on the side wall of the LED lamp body. The first bracket is sleeved on the outer surface of one end of the second bracket. A first tightening screw for locking is provided on the inner side of the first bracket. A mounting base is connected to one side wall of the first bracket through a locking mechanism.

[0016] Preferably, the connecting block, fixing plate, locking strip, and connecting groove are provided as follows: the connecting block is fixed to one side wall of the mounting base; a fixing plate is provided on one side of the connecting block; a locking strip is provided on the side wall of the connecting block; a connecting groove that mates with the connecting block is provided on the inner side of the first bracket; a stop block is provided on one side wall of the first bracket corresponding to the locking strip; and mounting holes are provided on the inner sides of both ends of the mounting base.

[0017] A method for using an LED lighting fixture mounting structure includes the following steps:

[0018] a. Fix the mounting base to the external wall through the mounting holes and bolts, loosen the first adjusting screw, let the second bracket extend from the inside of the first bracket, adjust the position of the LED lamp body, tighten the first adjusting screw after adjustment, then loosen the second adjusting screw, let the second bracket and the LED lamp body rotate, adjust the orientation of the LED lamp body, tighten the first adjusting screw after adjustment, and then inject cleaning fluid into the inside of the liquid storage mechanism.

[0019] b. The natural wind on the outside blows the fan blades to rotate, which in turn drives the drive screw to rotate. The drive screw drives the moving block to move towards one end of the guide plate through the rack on the lower surface of the moving block. The movement of the moving block causes the guide protrusion to slide in the guide groove, and the movement of the moving block causes the cleaning block to move.

[0020] c. The movement of the cleaning block drives the rubber scraper to move, cleaning the LED lamp body. At the same time, the movement of the cleaning block drives the slider to move. After the slider moves, it does not contact the support rod. Under the action of the elastic force of the connecting spring, the sealing block moves downward to seal the liquid outlet. At the same time, the movement of the slider causes the elastic rubber strip to stretch elastically.

[0021] d. When the guide protrusion moves to one end of the guide groove, the fixed block abuts against the moving block and moves upward. At this time, the return spring is compressed and shortened, and the guide protrusion slides upward through the guide groove. At this time, the rack separates from the drive screw.

[0022] e. Under the elastic tension of the elastic rubber strip and the guiding action of the guide groove, the guide protrusion moves to the upper end of the inner side of the guide groove. At the same time, the guide groove guides the moving block to reset to the other end of the guide plate. The moving block drives the cleaning block to reset. At this time, under the push of the elastic force of the reset spring, the moving block moves down to the starting position.

[0023] f. The cleaning block resets and drives the slider back to the starting position. At this time, the slider moves upward against the sealing block through the support rod. The connecting spring is compressed and shortened, and the liquid outlet opens, allowing the cleaning liquid to flow into the inside of the cleaning block and flow through the seepage hole to the surface of the LED lamp body. The LED lamp body is cleaned under the action of the rubber scraper. Repeat step bf to automatically clean the LED lamp body under the drive of natural wind.

[0024] g. After the LED lamp body is damaged, the first bracket can be pulled upwards to separate the connecting groove from the connecting block, and the LED lamp body can be disassembled. Later, the connecting groove and the connecting block can be directly matched, and the first bracket can be pressed downwards to install the LED lamp body. There is no need to unscrew the bolts to disassemble the mounting base.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] (1) By setting up a drive housing, fan blade, drive screw, moving block, connecting rod, slider and elastic rubber strip, it is easy to automatically clean the surface of the LED lamp body by natural wind drive, avoiding the need for manual cleaning of dirt attached to the surface of the LED lamp body, which is time-consuming and laborious. This device does not require additional power input to perform automatic cleaning action, saving the cost of additional motor drive, reducing manual labor and improving the use effect of the device.

[0027] (2) By setting a first adjusting screw, a second adjusting screw, a connecting block, a fixing plate, a clip and a connecting groove, it is easy to adjust the position of the installed LED lamp body in multiple directions. In addition, if the LED lamp body is damaged later, there is no need to fix the base with bolts. The LED lamp body can be disassembled and replaced for maintenance simply by pulling it out. This avoids the cumbersome disassembly and assembly of the LED lamp body after installation, which requires tools to unscrew the bolts and the risk of losing the bolts. This increases the practicality of the device. Attached Figure Description
