Description
Technical Field
[0001] The present invention belongs to the technical field of lighting equipment, and in particular relates to a foldable outdoor LED floodlight. Background Art
[0002] An outdoor LED floodlight is a directional lighting device designed for outdoor environments that uses LED as a light source. Its core features are high brightness and strong focusing, which can concentrate light onto a specific area. Compared with traditional floodlights, it has the advantages of low energy consumption, long life, and good weather resistance (the waterproof level is mostly IP65 and above, which can withstand rain and dust). It is also convenient for outdoor use and is often equipped with a foldable tripod bracket. The color temperature of the light source can be selected from warm white, pure white, etc. The power ranges from tens of watts to hundreds of watts. The brightness can be adjusted through the dimming system to meet the lighting needs of different scenarios. For example, the patent with authorization announcement number CN20659305U discloses a foldable outdoor LED floodlight.
[0003] At present, when using foldable outdoor LED floodlights, the unfolding operation of the triangular bracket in the folded state needs to be completed manually. The staff must first unfold the folded triangular legs one by one, and then unfold the retractable bracket to adjust the LED floodlight body to the appropriate height, thereby ensuring the range and effect of the LED floodlight body. However, this manual operation process is relatively cumbersome, which directly reduces the convenience of using the foldable outdoor LED floodlight; In addition, when the foldable outdoor LED floodlight is used in the summer, flying insects will gather in large numbers around the LED floodlight body due to their phototaxis. Too many flying insects will not only weaken the lighting effect of the LED floodlight body, but some flying insects attached to the surface of the LED floodlight body will also be easily burned to death by the heat emitted by the LED floodlight body when it is working. The body fluids produced after the death of the flying insects will form stubborn stains on the surface of the foldable outdoor LED floodlight, resulting in the need for staff to clean it laboriously after use, further reducing the convenience of using the foldable outdoor LED floodlight.

[0014] Compared with existing technologies, the advantages of a foldable outdoor LED floodlight are: 1. Through the folding bracket mechanism and driving mechanism, when the LED floodlight is needed for outdoor activities, the vacuum pump is first started through the control panel. The vacuum pump sucks air into the cylinder, and then the support tube and three oblique legs in the folding bracket mechanism are automatically unfolded by the air pressure, and the unfolding angle of the oblique legs is 60 degrees. Then the unfolded oblique legs are placed on the ground without manual operation by the staff. Moreover, after the use of the foldable outdoor LED floodlight, the folding and storage process is also simple. You only need to turn off the vacuum pump through the control panel. After the vacuum pump stops supplying air, the air pressure inside and outside the bottom of the cylinder is consistent, and the support tube automatically retracts under the action of the weight of the LED floodlight. During the retraction process, the oblique legs are automatically folded and stored by pulling the connecting ring, connecting rod, bottom ring and limit rod. This mechanism enables the foldable outdoor LED floodlight to have the function of automatic unfolding and folding, which can effectively improve the convenience of using the lamp.
[0015] 2. Through the provided connecting hose and driving mechanism, when the support tube moves to the top of the cylinder, the sealing ring presses the button of the press switch, and the press switch energizes the solenoid valve. After the solenoid valve is energized, the two ends are connected, and the air pump injects the air in the cylinder into the supporting tube through the solenoid valve. Finally, the air in the supporting tube is injected into the LED floodlight body through the connecting hose, accelerating the air flow inside the LED floodlight body, thereby accelerating the heat dissipation of the heating elements inside the LED floodlight body. The air after heat dissipation is injected into the rectangular tube through the bent pipe, and finally sprayed to the outside of the LED floodlight body through the air outlet, accelerating the air flow outside the LED floodlight body, further accelerating the heat dissipation effect of the LED floodlight body, and avoiding damage to the electronic components in the LED floodlight body due to high temperature. This mechanism enables the foldable outdoor LED floodlight to have efficient heat dissipation function, improves the protection capability of the lamp, and improves the reliability of the lamp.
[0016] 3. Through the set flying insect repellent mechanism, when the foldable outdoor LED floodlight is used in summer, the lens of the CCD visual camera continuously aims at the lighting area of the LED floodlight body, takes photos and transmits them to the industrial computer for processing, detects the number of black spots generated by flying insects in the photos (the amount of flying insects), and based on the flying insect amount data, the industrial computer dynamically adjusts the heating temperature of the micro heating rod. After the micro heating rod is powered on and heated, the insect repellent liquid at the liquid-inducing soft rod can be accelerated to evaporate. The components that are irritating or harmful to flying insects diffuse with the volatile gas to the periphery of the LED floodlight body, forming an insect repellent barrier, driving flying insects away from the LED floodlight body, and ensuring the lighting effect of the LED floodlight body. Due to the distance of flying insects, the surface of the foldable outdoor LED floodlight will not produce stubborn stains due to the flying insect body fluids, so that the foldable outdoor LED floodlight can be directly folded and stored after use, without the need for staff to clean the stains, saving time and effort. This mechanism enables the foldable outdoor LED floodlight to have the function of flying insect repellent. BRIEF DESCRIPTION OF THE DRAWINGS

The opposite sides of the two limiting circular blocks 13 are fixedly connected to the outer wall of the LED floodlight body 1.
[0022] The upper surface of the support bar 4 is fixedly connected with a driving mechanism 6 for unfolding the folding bracket mechanism 5.

[0023] The back of the LED floodlight body 1 is fixedly connected to a rectangular tube 14, and the wall of the rectangular tube 14 is fixedly connected to a flying insect repellent mechanism 7. The flying insect repellent mechanism 7 includes a CCD visual camera 71 and a transparent supply box 72 fixedly connected to the outer wall of the rectangular tube 14.

The wall of the rectangular tube 14 is fixedly connected to a bend pipe 74, and the bottom end of the bend pipe 74 is fixedly connected to the top shell of the LED floodlight body 1. The interior of the transparent supply box 72 is filled with an insect repellent liquid layer 76. The transparent supply box 72 can easily understand the remaining amount of the insect repellent liquid layer 76. The upper surface of the transparent supply box 72 is provided with a fixed through hole, and the hole wall of the fixed through hole is fixedly connected to an insulating tube 77. The bottom end of the heat-insulating tube 77 is fixedly embedded with a liquid-introducing soft rod 78, and the top end of the heat-insulating tube 77 is fixedly embedded with a micro-heating rod 79.

The air inlet end of the first branch pipe 710 is fixedly connected to the outer wall of the curved tube 74, and the bottom end of the second branch pipe 75 is fixedly connected to the tube wall of the rectangular tube 14.

[0024] A threaded hole is provided on the upper surface of the transparent supply box 72, and a sealing plug 8 is threadedly connected to the wall of the threaded hole. Opening the sealing plug 8 can facilitate the replenishment of the insect repellent liquid in the transparent supply box 72. The bottom end of the liquid-introducing soft rod 78 extends to the bottom end of the insect repellent liquid layer 76. The insect repellent liquid layer 76 is any one of lemongrass essential oil, peppermint essential oil and mosquito coil liquid.
[0025] The battery 9 is fixedly connected to the inner wall of the bottom end of the bottom shell 3. The outer wall of the bottom shell 3 is provided with a mounting hole, and the hole wall of the mounting hole is fixedly connected to the control panel 16. The control panel 16 can be conveniently used through the control of the lamp.
[0026] The vacuum pump 62 and the LED floodlight body 1 are electrically connected to the battery 9 through the control panel 16, the solenoid valve 64 is electrically connected to the battery 9 through the press switch 65, the CCD visual camera 71 is electrically connected to the input end of the industrial computer 61 through a wire, and the micro heating rod 79 is electrically connected to the output end of the industrial computer 61 through a wire. The above-mentioned electrical equipment and electrical connections are all existing technologies and will not be repeated here.
[0027] The operating principle of the present invention is described as follows: when the LED floodlight is needed for outdoor activities, the air pump 62 is first started through the control panel 16. The air pump 62 sucks the air in the bottom shell 3, and the bottom shell 3 sucks the outside air for replenishment through the filter screen 67 and the filter sponge block 66. The air is filtered and purified when passing through the filter screen 67 and the filter sponge block 66. Then the air pump 62 injects air into the cylinder 51 through the delivery hose 63. As the air in the cylinder 51 increases, the air pushes the support tube 52 upward through the sealing ring 510. The support tube 52 drives the height of the LED floodlight body 1 to rise through the U-shaped plate 11, so that the height of the LED floodlight body 1 reaches the required height for use, thereby ensuring the lighting range of the LED floodlight body 1. When the support tube 52 moves upward, the support tube 52 drives the bottom ring 56 to move upward through the connecting ring 54 and the connecting rod 57. The bottom ring 56 opens the folded oblique support leg 512 through the hinged limit rod 513. When the sealing ring 510 moves After reaching the top of the cylinder 51, it is blocked and no longer moves, and the expansion angle of the inclined legs 512 is 60 degrees. Then, the expanded inclined legs 512 can be placed on the ground, without the need for staff to laboriously expand the triangular legs one by one, or manually pull out the retracted brackets, which saves time and effort. Moreover, after the foldable outdoor LED floodlight is used, the folding and storage process is also simple, and it is only necessary to turn off the air pump 62 through the control panel 16. After the air pump 62 stops supplying air, the air pressure inside and outside the bottom of the cylinder 51 is consistent, and the support tube 52 automatically retracts under the gravity of all structures on the top of the support tube 52, and the inclined legs 512 will also move closer to the bottom shell 3 under the cooperation of their own gravity, further ensuring the effect of automatic folding. During the retraction process, the inclined legs 512 are automatically folded and stored by pulling the connecting ring 54, the connecting rod 57, the bottom ring 56 and the limit rod 513. This mechanism enables the foldable outdoor LED floodlight to have the function of automatic expansion and folding, which can effectively improve the convenience of using the lamp. When the support tube 52 moves to the top of the cylinder 51, the sealing ring 510 presses the button of the press switch 65, and the press switch 65 energizes the solenoid valve 64. After the solenoid valve 64 is energized, the two ends of the solenoid valve 64 are connected, and the air in the cylinder 51 injected by the air pump 62 enters the support tube 52 through the solenoid valve 64. Finally, the air in the support tube 52 is injected into the LED floodlight body 1 through the connecting hose 53, accelerating the air flow inside the LED floodlight body 1, thereby accelerating the heat dissipation of the heating element inside the LED floodlight body 1. The air after heat dissipation is injected into the rectangular tube 14 through the bend pipe 74, and finally ejected to the LED floodlight body 1 through the air outlet 73. D outside the LED floodlight body 1, accelerates the air flow outside the LED floodlight body 1, further accelerates the heat dissipation effect of the LED floodlight body 1, and prevents the electronic components in the LED floodlight body 1 from being damaged by high temperature. In addition, the airflow ejected from the air outlet 73 can also block external dust and small floating objects from approaching the CCD visual camera 71 as much as possible, ensuring a clear field of view for the CCD visual camera 71 and improving the accuracy of the CCD visual camera 71 in detecting the density of flying insects. This mechanism enables the foldable outdoor LED floodlight to have a high-efficiency heat dissipation function, improves the protection capability of the lamp, and improves the reliability of the lamp. When the foldable outdoor LED floodlight is used in summer, first inject insect repellent into the transparent supply box 72 to form an insect repellent liquid layer 76 in the transparent supply box 72. The insect repellent liquid will keep the liquid guide rod 78 moist through osmosis, ensuring that the micro heating rod 79 is always in contact with the insect repellent. During this process, the CCD visual camera 71 starts working synchronously. The lens of the CCD visual camera 71 is continuously aimed at the lighting area of the LED floodlight body 1. The light irradiated on the chip is converted into an electrical signal through the internal charge coupled device (CCD). After processing, a digital image is generated. The generated lighting area photo is transmitted to the industrial computer 61 (the model of the industrial computer 61 is Advantech ARK-7060 industrial control host) in real time. The industrial computer 61 runs a pre-stored photo comparison program to analyze the image. The program analyzes the image by identifying the insects in the image caused by flies. The black spots formed by insects blocking the light are counted and converted into flying insect quantity data. Based on the flying insect quantity data, the industrial control computer 61 dynamically adjusts the heating temperature of the micro heating rod 79. When the flying insect quantity increases, the heating temperature increases (maximum 140°C), and when the flying insect quantity decreases, the heating temperature decreases (minimum 80°C). After the micro heating rod 79 is powered on and heated, the heat is quickly transferred to the liquid introduction soft rod 78, prompting the insect repellent liquid adsorbed in the liquid introduction soft rod 78 to evaporate faster. The components that are irritating or harmful to the flying insects diffuse with the volatile gas to the periphery of the LED floodlight body 1, forming an insect repellent barrier. For example, when the mosquito coil liquid is heated, the pyrethroid compounds in the mosquito coil liquid evaporate. The pyrethroid compounds have a stimulating effect on the flying insects and keep the flying insects away from the LED floodlight body 1. The pyrethroid compounds can even kill the flying insects.
[0028] At this time, part of the air in the curved pipe 74 enters the heat-insulating tube 77 through the first branch pipe 710, carries the volatile substances into the rectangular tube 14 through the second branch pipe 75, and is finally sprayed near the LED floodlight body 1 through the air outlet 73 of the rectangular tube 14, driving the flying insects away from the LED floodlight body 1, ensuring the lighting effect of the LED floodlight body 1. Since the flying insects are away, the surface of the foldable outdoor LED floodlight will not produce stubborn stains due to the body fluids of the flying insects, so that the foldable outdoor LED floodlight can be directly folded and stored after use, and there is no need for the staff to clean the stains, which saves time and effort. If the amount of black spots caused by flying insects in the photo is zero, it means that there are no flying insects at the LED floodlight body 1, and the micro heating rod 79 is not started. This mechanism enables the foldable outdoor LED floodlight to have the function of repelling flying insects and can ensure the lighting effect of the lamp. There is no need to clean it after use, which saves time and effort, and further improves the convenience of using the lamp.
[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
