Detailed implementation manners

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] Please refer to Figures 1-5 , the present invention provides a technical solution: an LED explosion-proof floodlight, including a floodlight bracket 5. A multi-functional tube 9 is provided at the bottom of the floodlight bracket 5. An audio is provided at the rear end of the multi-functional tube 9. The audio is controlled by a control system and has functions of broadcasting and alarming. An installation groove one 19 is provided at the top of the floodlight bracket 5. The floodlight bracket 5 and the lower bracket 6 are fixedly connected together by setting a bolt one 18 in the installation groove one 19. An installation groove two 17 is provided at the bottom of the lower bracket 6. The bolt one 18 connects the two through the installation groove one 19 and the installation groove two 17; A floodlight housing 7 is arranged between the lower brackets 6. A number of LED lamp cores 10 are arranged on the front surface of the floodlight housing 7. A number of pin holes are arranged on the front edge of the floodlight housing 7. A color-changing screen 14 is arranged on the front surface of the floodlight housing 7. The color-changing screen 14 is powered on and regulated by a control system. A number of pin holes are arranged on the edge of the color-changing screen 14. A protective shell 15 is arranged outside the color-changing screen 14. A number of pin holes are arranged on the edge of the protective shell 15. The protective shell 15, the color-changing screen 14 and the floodlight housing 7 are sequentially connected together from outside to inside by using a pin rod 16. The color-changing screen 14 is protected by the protective shell 15. The color is adjusted through the color-changing screen 14, so that the light colors projected by the LED lamp cores 10 are inconsistent. Due to the limitation of the camping site, large lamps cannot be carried, nor can a large number of lamps be carried. By using the color-changing screen 14 to change the light color projected by the LED lamp cores 10, the function of generating several colors by a single lamp can be realized, providing a better atmosphere for camping. Compared with installing lamp cores of different specifications in the same device to achieve the purpose of releasing different colors, this device changes the color displayed by the color-changing screen 14, and then changes the light color released by the lamp core. The overall volume of the device is smaller, and since the installed lamp cores are of the same specification, the light brightness released by the lamp cores is higher; Lamp cores of different specifications refer to, for example, if it is necessary to release red, yellow, and green light, then lamp cores that can release red light, lamp cores that can release yellow light, and lamp cores that can release green light are installed in the device. Each lamp core operates independently, resulting in insufficient light brightness when a single color of light needs to be released; The protective shell 15 is a hollow frame. Different transparent shielding materials such as glass and plastic can be selectively installed on the protective shell 15. A thickened sealing layer is arranged on the inner side wall of the protective shell 15. The thickened sealing layer is located between the protective shell 15 and the color-changing screen 14, effectively preventing water seepage at the LED lamp core 10 or flammable gas from entering the LED lamp core 10. At the same time, the two sealing and protective substances of the protective shell 15 and the color-changing screen 14 block the entry of external gas, making the overall explosion-proof performance of the LED floodlight higher; Reinforcing rods 11 are arranged on the side wall of the floodlight housing 7. Installation grooves three 12 are arranged on the reinforcing rods 11. Fixing parts 13 are arranged at the tops of both sides of the lower brackets 6. The lower brackets 6 and the floodlight housing 7 are connected by inserting the fixing parts 13 into the installation grooves three 12; A pull rod 8 is arranged on the top of the floodlight housing 7 to facilitate personnel carrying; The whole set of LED floodlights is equipped with a camp fixing base 1. A number of fixing jacks 2 are arranged on the base 1. The base 1 is fixed to the ground by using fixing pins through the jacks 2. A telescopic rod 3 is arranged on the top of the base 1. The height of the telescopic rod 3 is adjustable. A fixing hole 20 is arranged at the bottom of the floodlight bracket 5. The telescopic rod 3 can be inserted into the fixing hole 20 to connect the telescopic rod 3 and the floodlight bracket 5; A rotary switch 24 is provided on the pull rod 8. An inductor connected to the motor 21 is provided inside the rotary switch 24. The motor 21 is provided on the inner wall of the fixing hole 20. The motor 21 powers the clamping rod 22. The clamping rod 22 has a telescopic function. A clamping hole 23 is provided at the top of the telescopic rod 3. When a person rotates the rotary switch 24, the motor 21 can be driven to start. When the motor 21 starts, it drives the clamping rod 22 to extend and engage with the clamping hole 23, thereby connecting the telescopic rod 3 and the floodlight bracket 5. Then, the telescopic rod 3 is electrically controlled to rise, so that the telescopic rod 3 rises to the required height, and the lighting range is expanded by raising the LED floodlight. If the LED floodlight needs to be disassembled, first electrically control the telescopic rod 3 to descend, so that the telescopic rod 3 descends to the bottom, and then reverse the rotary switch 24 to drive the motor 21 to start. When the motor 21 starts, it drives the clamping rod 22 to retract. At this time, the LED floodlight can be lifted. The assembly method provides two layout modes for the LED floodlight. One is to place it on the ground, providing a more concentrated light source through ground lighting, with good lighting effects. The other is to arrange the LED floodlight in the air to increase the lighting range. At the same time, the assembled lighting structure is convenient for personnel to carry. Larger equipment such as the telescopic rod 3 can be carried in a small volume form. The lighting brightness of the LED floodlight is much higher than that of small lighting equipment. With the assistance of equipment such as the telescopic rod 3, the lighting range can be increased, which can sufficiently meet the camping needs and there is no worry about power consumption.

[0017] According to the camping needs, different numbers of LED floodlights are installed around the campsite, and several LED floodlights are used to provide omnidirectional lighting for the campsite. The specific quantity and position settings need to be determined according to the terrain of the campsite. The LED floodlight has a self-adjusting function. An infrared scanning device and a camera module are provided on the top of the multifunctional tube 9. The infrared scanning device continuously detects whether there are organisms around, and then automatically adjusts the brightness of the LED lamp core 10 according to the monitoring data of the infrared scanning device. The LED lamp core 10 has two brightness levels, low brightness and high brightness. If the infrared scanning device detects organisms around, it automatically adjusts the brightness of the LED lamp core 10 to the high brightness mode to illuminate the organisms and at the same time provide a better shooting environment for the camera module. If the infrared scanning device detects that there are no organisms around, it automatically adjusts the brightness of the LED lamp core 10 to the low brightness mode to provide a better rest environment for the camping and resting people and at the same time save energy. The camping lighting at the campsite all uses mobile power supplies. By controlling the brightness of the LED lamp core 10, the usage duration of the mobile power supply can be increased; The detection of the infrared scanning device has a range, as shown in the appendix Figure 5As shown, if it exceeds the detection range, the infrared scanning device cannot detect. The infrared scanning device classifies the biological movement mode into an entry mode and a departure mode. The entry mode means that a living being enters the detection range from outside the detection range, and the departure mode means entering from within the detection range to outside the detection range. During camping and rest, the personnel can adjust the infrared scanning device and the LED floodlight to the sleep mode through the control system. Or if the infrared scanner does not detect the presence of a living being within the set duration H, the control system automatically adjusts the LED floodlight and the infrared scanning device to the sleep mode. In the sleep mode, if there is a living being in the entry mode for the infrared scanning device, the control system immediately adjusts the brightness of the LED lamp core 10 to the high-brightness mode and drives the sound alarm simultaneously to provide a safe environment for camping and rest; The front end of the multifunctional tube 9 is provided with an insect repellent spray port 4. The insect repellent spray port 4 is connected to an insect repellent liquid tank arranged inside the multifunctional tube 9. The pump head inside the insect repellent liquid tank is controlled by the control system. The control system starts the pump head at a fixed frequency, and uses the pump head to spray the insect repellent from the insect repellent spray port 4. Since insects are attracted to light and gather in front of the LED lamp core 10, spraying the insect repellent at a fixed frequency can drive away mosquitoes and improve the lighting brightness of the LED lamp core 10; It is recommended that the orientation of all the LED lamp cores 10 be towards the camping room during installation to maximize the function of the LED lamp cores 10; In the entire camp lighting combination fixture, an LED floodlight can also be placed in each camping room as the lighting source inside the camping room. At the same time, it can also be connected to the outdoor LED floodlights. If the outdoor LED floodlight is adjusted to the high-brightness mode in the sleep mode, the control system forcibly drives the LED floodlight inside the camping room to also be adjusted to the high-brightness mode to wake up the people inside the camping room and at the same time give a warning to the living beings in the entry mode outdoors, further enhancing camping safety; Using the elevation function of the telescopic rod 3 to raise the LED floodlight to a high place also improves the sensitivity of the light sensor installed on the back of the LED floodlight, enabling the light sensor to more accurately capture the outdoor light value. The control system can set the sensing value K1 of the light sensor, that is, when the light value received by the light sensor reaches the set sensing value K1, the LED lamp core 10 is turned off and there is no need for continuous lighting; In the sleep mode, the light sensor can be set by the control system to receive a set light value K2. The light value K2 is the light value range when sunrise occurs. When the light sensor receives the set light value, the control system wakes up the person through the LED floodlights in the camping room, reminding the person that they can watch the sunrise and avoiding the time spent waiting outdoors. Due to weather factors, it is not possible to watch the sunrise every day. If the sunrise cannot be seen due to weather factors while waiting for the sunrise, it will be a waste of time and the camping experience will be poor. The LED floodlights and their connection structure are used to effectively observe the time point when the sunrise occurs, wake up the person at the moment of sunrise, improve the comfort of the person camping. At the same time, the control system adjusts the color-changing screen 14 and the LED lamp core 10 to white light, and cooperates with the insect repellent nozzle 4 to provide an environment with fewer mosquitoes for outdoor sunrise viewing. An appropriate amount of white light can increase the surrounding illumination and improve the viewing conditions. When the light value received by the light sensor reaches the set induction value K1, it means that the sunrise is over and the outdoor illumination is too high, and the LED lamp core 10 is turned off.
