Description
TECHNICAL FIELD
[0001] The application relates to the technical field of lamps, in particular to an LED floor lamp based on human body sensing. BACKGROUND
[0002] With the rapid development of the smart home industry, the LED floor lamp based on human body sensing has become one of the core lighting devices in the living room, bedroom, study and small office space of a family because it has both lighting function and decoration attribute. The LED floor lamp based on human body sensing gradually replaces the traditional incandescent lamp and fluorescent lamp to become the mainstream light source selection of the floor lamp because of the advantages of low energy consumption, long service life (the average service life can reach 5-8 million hours) and soft light. Meanwhile, the popularity of the human body sensing technology (such as passive infrared sensing PIR and microwave sensing) promotes the upgrade of the LED floor lamp based on human body sensing from "manual switch control" to "intelligent sensing control", realizes the convenient experience of "people come, light on, people go, light off", and further meets the needs of users for energy saving and non-sensing interaction.
[0003] At present, the mainstream LED floor lamp based on human body sensing on the market has the basic sensing lighting function, but there are still many technical problems in the structural design, lighting flexibility and stability, which are difficult to meet the diversified and high-quality use needs of users. The specific problems are as follows: the existing LED floor lamp based on human body sensing mostly adopts an integrated welded or fixed assembly structure, the height of the lamp pole is fixed at the factory, and the height cannot be flexibly adjusted according to the use scene, so that the same floor lamp is difficult to adapt to the installation needs of different house types or different areas. In addition, the direction of the lamp group is fixed - the top lighting lamp group of the LED floor lamp based on human body sensing is mostly 360° fixed light emission, and the side wall LED lamp group (if equipped) is directed to a single direction. When the human body moves in the space (such as from the sofa in the living room to the balcony, from the desk to the bookshelf), the "people in the lighting blind area" situation is easy to occur, and dynamic light chasing cannot be realized. CONTENT OF THE UTILITY MODEL
[0004] In order to make up for the above shortcomings, the application provides a human body induction based LED floor lamp to solve the problems in the background art.
[0005] To achieve the above object, the utility model adopts the technical scheme that:
[0006] A human body induction based LED floor lamp, comprising a top rod and a lighting lamp group equipped at the top of the top rod, and a LED lamp group mounted on the side wall, characterized in that: a support assembly is arranged at the bottom end of the top rod, a joint assembly is fixed by screw thread at the bottom end of the support assembly, the joint assembly is mounted on the surface of a base, a driving motor is bolted at the top of the base, and the output shaft of the driving motor is connected with the joint assembly by plug-in connection through a plug-in slot formed in the bottom of the joint assembly and the surface of the base.
[0007] Further, the support assembly is composed of a plurality of hollow pipes and a plurality of double-headed threaded joints, the hollow pipes are fixed by bolts through the double-headed threaded joints, and the bottom end of the top rod is fixed by screw thread with the top end of the hollow pipes through the double-headed threaded joints.
[0008] Further, the joint assembly is composed of a bearing, a positioning column, a threaded head, four groups of butt joints and four fixing blocks, the bearing is embedded in the surface of the base, the positioning column is in interference fit with the inner ring of the bearing, the top end and the bottom end of the threaded head are integrally formed, a plug-in slot is formed in the bottom, and the output shaft of the driving motor is plug-in connected, four groups of butt joints are formed at equal intervals on the contact surface between the inner ring of the bearing and the outer wall of the positioning column, and four fixing blocks are respectively mounted in the four groups of butt joints.
[0009] Further, the base is hollow, the bottom is treated to prevent slipping, two arc grooves are formed, the bearing is embedded in the surface of the base, and the driving motor is accommodated in the hollow space.
[0010] Further, two heat dissipation openings are formed on the both sides of the outer wall of the base, and the two heat dissipation openings and the hollow cavity formed in the bottom of the base are in communication.
[0011] Further, the driving motor is equipped with a controller and is electrically connected with the human body induction technology mounted on the LED lamp group.
[0012] Further, the lighting lamp group and the LED lamp group are electrically connected with the battery column mounted inside the hollow pipe.
[0013] The utility model has the following beneficial effects:
[0014] 1、The utility model support assembly is fixed by hollow pipe and double -end thread joint bolt, and the top rod, support assembly and joint assembly are all connected through thread to realize modular assembly. Users can freely increase or decrease the number of hollow pipes according to the use scene (such as long lamp pole for high space in living room, short lamp pole for low space in bedroom), which can adjust the overall height of floor lamp without replacing the whole lamp, and adapt to the installation requirements of different house types or different areas. At the same time, the volume of each part (top rod, hollow pipe and base) is small after disassembly, which is convenient for moving and storage when idle, avoiding the problem of occupying a large storage space of traditional integrated floor lamp. In addition, the joint assembly is fixed at the bottom end of the support assembly through thread, and the positioning column and the bearing on the surface of the base are interference fit, and the bottom plug-in slot and the output shaft of the driving motor are plug-in connection. During assembly, only the thread is screwed and the output shaft is inserted to complete the fixation. When disassembling, reverse operation can separate the top rod, support assembly and base. When the driving motor fails and needs to be repaired or the LED lamp group needs to be replaced, the base and the upper structure need to be separated for individual repair, which reduces the maintenance threshold of ordinary users and reduces the time cost of professional maintenance.
[0015] 2、The controller of the driving motor is electrically connected with the human body sensing technology on the LED lamp group. When the human body sensing module detects the change of human body position (such as moving from the sofa in the living room to the nearby balcony), the controller can drive the output shaft to rotate in real time, drive the joint assembly, support assembly and top rod to rotate around the base (the rotation angle can be set to 0-180° through program), so that the LED lamp group on the side wall and the lighting lamp group on the top always face the human activity area. Compared with the traditional fixed direction floor lamp, the blind area problem of "people outside the lamp lighting range" caused by human movement can be avoided, which is especially suitable for scenes such as large living room and open office that need dynamic lighting. In addition, the lighting lamp group on the top can provide 360° global basic lighting (such as overall lighting of living room at night), and the LED lamp group on the side wall can focus on local area (such as reading beside sofa and working beside desk), both of which are powered by the battery column inside the hollow pipe and are controlled by human body sensing linkage. When a person approaches, both lamp groups are turned on at the same time, and when the person leaves, the lamp groups are turned off after a delay. If a person is stationary in a local area (such as reading for a long time), the human body sensing module continuously detects the static human body (combined with the thermal imaging or optimized PIR technology mentioned in the foregoing), which can keep the LED lamp group always on, avoiding the embarrassment of traditional sensing lamp "not moving". This "global + local" double lamp group design takes into account the lighting needs of different scenes, improving the practicality and energy saving of lighting. BRIEF DESCRIPTION OF DRAWINGS

Detailed Implementation
[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0026] Example:
[0027] Please see Figure 1 , Figure 2 The human body sensing-based LED floor lamp includes a top rod 1 and a lighting group 2 equipped on the top of the top rod 1, and an LED light group 3 installed on the side wall.
[0028] Among them, the top rod 1 serves as the core connecting component. On the one hand, it provides a stable mounting carrier for the lighting group 2 and the side wall LED group 3, ensuring that the two types of light groups are accurately assembled and realize their functional layout. On the other hand, the bottom end of the top rod 1 is threaded to the top end of the hollow tube 41 of the support component 4 through the double-ended threaded joint 42, thereby stably mounting the entire light group on the top of the support component 4, forming a continuous support structure of "top rod-support component".
[0029] The design of lighting unit 2 and LED light unit 3 achieves a dual-light design of "full coverage + local lighting" and is equipped with human body sensing technology. The human body sensing requirement of the LED floor lamp is essentially "detecting the presence / activity of a human body → triggering the light switch / adjustment". The core capability of thermal imaging technology is to generate a temperature image by detecting the infrared energy of the thermal radiation of an object, and then identify that the "human body" temperature is about 37°C, which is significantly different from the ambient temperature, fully meeting this control logic. When users are reading or in other scenarios that require precise lighting, lighting unit 2 can provide full coverage basic lighting, creating a soft light environment for the entire space; however, due to the radiation characteristics of the light source, its brightness will naturally decrease with increasing distance, resulting in reduced light intensity in areas far from the lamp body, such as the far end of the desk and the corner of the sofa, making it difficult to meet the need for localized high brightness when reading. The LED light group 3 on the side wall can focus on specific areas to form local supplementary lighting, accurately covering the core activity range of the user reading, effectively filling the brightness gap caused by the distance attenuation of the lighting group 2. This not only avoids visual fatigue caused by excessively bright overall lighting, but also ensures the clarity of the local light required for reading, achieving a synergistic adaptation of "overall basic lighting + local precise supplementary lighting".
[0030] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 A human body sensing-based LED floor lamp includes a top rod 1 with a support component 4 at its bottom. A connector component 5 is threadedly fixed to the bottom of the support component 4. The connector component 5 is mounted on the surface of a base 6. A drive motor 7 is bolted to the top of the base 6. The output shaft of the drive motor 7 is inserted and fixedly connected to the bottom of the connector component 5 through a groove on the surface of the base 6. The support component 4 consists of several hollow tubes 41 and several double-threaded connectors 42. The connector component 5 consists of a bearing 51, a positioning post 52, a threaded head 53, four sets of mating grooves 54, and four fixing blocks 55. The base 6 is hollow and has a non-slip bottom with two arc grooves 61.
[0031] The modular and detachable design of the support component 4 is the core of the flexible height adaptation of the floor lamp: by increasing or decreasing the number of hollow tubes 41, users can freely adjust the overall height of the device according to different usage scenarios, such as a 2.0m lamp post for a high living room or a 1.2m lamp post for a low bedroom, adapting to diverse space needs without replacing the entire lamp, thus solving the limitation of the fixed height of traditional integrated floor lamps. To ensure the structural stability and load-bearing capacity of the support component, several hollow tubes 41 and several double-threaded connectors 42 are made of high-strength rigid materials, and also have lightweight and deformation resistance characteristics, which can stably support the overall weight of the top rod 1, the lighting group 2, and the LED light group 3, avoiding problems such as lamp post bending and tilting after long-term use. In terms of connection structure design, several hollow tubes 41 have internal threads at both ends, which are matched with the double-headed bolt ends of the double-threaded connectors 42. The surface of the external threads is galvanized for rust prevention, which not only enhances wear resistance but also prevents rust in humid environments, thus avoiding disassembly difficulties. During assembly, simply screw one end of the double-ended threaded connector 42 into the internal thread of a hollow tube 41, and screw the other end into the internal thread of another hollow tube 41 or the bottom of the push rod 1. The internal thread specification of the bottom of the push rod 1 is the same as that of the hollow tube 41. Rigid fixation is achieved through thread engagement, ensuring that the support assembly 4 is not loose. At the same time, the detachable nature of the threaded connection also makes it easy for users to quickly disassemble and adjust the height, or replace the hollow tube 41 or the connector separately when the component is damaged, reducing maintenance costs.
[0032] The top rod 1 or the hollow tube 41 connected to it by threads is equipped with a battery inside, and a charging port is provided on the outer wall for charging. The battery is connected to the wiring of the lighting assembly 2 and the LED light assembly 3 fixed on the top rod 1, so that the lamp is freed from wire constraints and avoids safety hazards.
[0033] The connector assembly 5 plays a dual core role: firstly, it serves as a crucial connecting carrier between the support assembly 4 and the base 6, ensuring a stable connection between the hollow tube 41 and the base 6; secondly, through linkage with the output shaft of the drive motor 7, it transmits the motor torque to the support assembly 4, providing the power foundation for the overall steering of the lamp assembly, making it the core hub of "structural support" and "power transmission". The bearing 51 provides stable support: The bearing 51 is embedded in the pre-set mounting hole on the surface of the base 6 using a press-fit and anaerobic adhesive method. Its inner ring forms a precise fit with the outer wall of the positioning post 52, providing radial support for the positioning post 52 and reducing rotational friction resistance through the ball bearing structure. This ensures smooth and uninterrupted rotation of the upper lamp assembly when the positioning post 52 drives it. Simultaneously, the double-sided dust cover design prevents dust from entering and affecting rotational accuracy, extending service life. The threaded head 53 serves as a connection and fixing mechanism: The threaded head 53, integrally formed at the top of the positioning post 52, precisely matches the external thread with the internal thread at the bottom of the hollow tube 41. During assembly, only manual tightening is required to achieve rigid fixing of the hollow tube 41 and the positioning post 52. The threaded connection ensures the load-bearing stability of the support component 4 and also provides convenient disassembly and assembly, facilitating users to adjust the height of the light pole or maintain the components. The mating grooves 54 and fixing blocks 55 provide limiting and fixing functions: Four sets of mating grooves 54, formed on the outer wall of the positioning post 52 and the inner ring of the bearing 51, cooperate with the wear-resistant fixing blocks 55 embedded in the grooves. The fixing blocks 55 are firmly fixed to the mating grooves 54 with epoxy resin adhesive, and their outer surface is flush with the outer wall of the positioning post 52. This prevents relative sliding between the positioning post 52 and the inner ring of the bearing 51, ensuring no radial offset during torque transmission and not affecting the smooth rotation of the positioning post 52. It also prevents direct metal-to-metal contact that could cause abnormal noise.
[0034] The base 6 is designed with "stable load-bearing" as its core objective. Its main body is made of high-density material, increasing its own weight to create a stable center of gravity support. This effectively counteracts the weight shift of the upper lighting assembly 2, LED assembly 3, and support component 4, preventing damage or safety hazards caused by collisions or tipping, and providing a reliable foundation for the entire lamp. The base 6 has a pre-designed internal cavity matching the size of the drive motor 7. Threaded holes are pre-drilled in the cavity wall, allowing the drive motor 7 to be horizontally fixed inside with bolts. This ensures precise alignment of the motor output shaft with the insertion slot of the positioning post 52 and provides space for heat dissipation, preventing heat buildup from affecting performance. The bottom of the base 6 features double anti-slip treatment—an anti-slip pad is attached to the bottom surface, and two symmetrical arc grooves 61 are created on the bottom. These grooves increase the complexity of the contact texture between the base 6 and the ground, dispersing the pressure of the lamp's weight on the ground. Even on smooth floors such as ceramic tiles or wooden floors, this effectively prevents the base 6 from shifting, further enhancing the overall stability of the floor lamp.
[0035] The drive motor 7 is used to drive the support assembly 4 to rotate. The drive motor 7 is equipped with a controller electrically connected to human body sensing technology, and is fixed in the cavity inside the base 6 by bolts. The output shaft is fixedly connected to the insertion slot opened at the bottom of the positioning column 52. The controller starts and stops the drive motor 7, which drives the positioning column 52 to drive the hollow tube 41 and the lighting group 2 and LED group 3 installed on the top rod 1 to rotate, so that the LED group 3 can achieve dynamic tracking light.
[0036] The heat dissipation vent 8 is designed to accelerate the heat dissipation of the drive motor 7. When the drive motor 7 is working and generating heat, the hot air rises naturally in the cavity, while the external cold air flows from one heat dissipation vent 8 to another, quickly carrying away the heat from the motor surface. This can reduce the motor's operating temperature by 8-12℃, preventing heat accumulation that could lead to aging of the motor coils and a decrease in torque, and significantly extending the motor's service life.
[0037] It should be noted that the specific models and specifications of the lighting unit 2, LED light unit 3, and drive motor 7 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
[0038] The power supply and operating principle of the lighting assembly 2, the LED light assembly 3, and the drive motor 7 are clear to those skilled in the art and will not be described in detail here.
[0039] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
