Existing spotlights are generally linked through an external human body induction device. The human body induction device controls the spotlight to light up, achieving the lighting effect of turning on when people come and turning off when people leave.

[0003] However, in this scenario, usually the human body induction device and the spotlight are installed separately. The spotlight is generally installed on the ceiling board. If the induction device controls the spotlight one by one, many induction devices need to be set, which brings inconvenience to installation; if one induction device controls multiple spotlights, a series of problems such as untimely triggering, non-triggering or false triggering will be caused.

The radar module is arranged in the interlayer space between the first cavity and the light-transmitting cavity to reduce the light propagating from the inside of the lamp housing to the brightness detection component, so that the brightness detection component can more accurately detect the ambient brightness when the light is on.

[0021] Another object of the present invention is to provide a human body sensing spotlight, in which only a small amount of light enters the interlayer space between the first cavity and the light transmission cavity, preventing the interlayer space from being too bright and causing light to penetrate through the hidden plate, thereby avoiding the radar module from casting a shadow on the hidden plate.

[0078] In the description of the present invention, the orientation or positional relationship indicated by the terms "inner", "outer", "horizontal", "vertical", "upper", "lower", "top", "bottom", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and does not require the present invention to be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0079] In the description of the specification of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0080] In the description of the specification of the present invention, unless otherwise clearly defined and limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection, or a connection that allows mutual communication; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0081] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. The technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement it. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0082] Generally, the human body sensing device and the spotlight are installed separately. The spotlight is generally installed on the ceiling board. If the sensing device controls the spotlight one by one, a lot of sensing devices need to be set, which brings inconvenience to the installation; if one sensing device controls multiple spotlights, a series of problems will arise: the sensing position is inconsistent with the lighting position, resulting in the spotlight not being lit in time, and when the user is too far away from the sensing device, the nearby spotlight cannot be lit; the sensing device has high requirements for the installation position, and if the installation position is improper, non-triggering or false triggering will occur. Therefore, there is an urgent need in the market today for a spotlight with a human body sensing function.

[0083] It is difficult to integrate a human body sensing module inside the existing spotlight because the human body sensing module needs to be set on the light-emitting side of the spotlight so that the human body sensing module senses in the light-emitting direction. However, a horn-shaped reflecting bowl is provided on the light-emitting side of the existing spotlight, and the light is emitted outward through the light-emitting port of the reflecting bowl. The light-emitting port occupies most of the area of the light-emitting side, resulting in the inability to install the human body sensing module on the light-emitting side.

[0084] To solve the above problems, according to the first aspect of the present invention, a human body sensing spotlight 100 is provided. Please refer to Figures 1 - 23 , the human body sensing spotlight 100 provided by the present invention will be specifically explained. Specifically, as Figures 1 - 3As shown, the human body induction spotlight 100 includes: a radar module 2 for radiating radar waves to detect the presence of a human body; a light-emitting component 3 for radiating visible light for illumination; a lamp housing 1, with the radar module 2 and the light-emitting component 3 placed inside it. One side of the lamp housing 1 forms a radiation area, which includes: a first area 411 for radiating visible light and a second area 412 for radiating radar waves. Among them, the lamp housing 1 can be a single housing or a combination of multiple housings. The radar module 2 can be understood as an assembly composed of a radar module, a radar circuit board 21, and other electronic components on the radar circuit board 21. The radar module 2 radiates radar waves externally. After the radar waves are blocked by objects in the environment and reflected, the radar module 2 receives the reflected radar waves and determines whether there is a human body within the detection range based on the Doppler principle. Compared with an infrared sensor, the advantage of the radar module 2 is that it can sense the subtle movements of the human body, such as breathing and heartbeat. When the human body is stationary, the radar module 2 can sense the presence of the human body, thereby controlling the light-emitting component 3 to maintain the lit state.

[0085] In the present invention, the radar module 2 and the light-emitting component 3 are integrated inside the lamp housing 1, enabling the spotlight to simultaneously have the functions of illumination and human body induction. Users do not need to install a separate human body induction device and do not need to adjust the induction direction, greatly improving the installation convenience. And because the first area 411 and the second area 412 are set on the same side of the lamp housing 1, the visible light and the radar waves are both emitted towards the same side, and the illumination direction and the induction direction tend to be the same direction. When the user approaches the illumination area, the spotlight can sense the human body more timely, improving the response speed and induction accuracy, and avoiding problems such as untimely triggering, non-triggering, or false triggering of the human body induction spotlight 100.

[0086] In the embodiment of the present invention, the first area 411 and the second area 412 are independent of each other, so as to facilitate the integration of the radar module 2 inside the lamp housing 1, enabling the spotlight to take into account both the illumination and human body induction functions. At the same time, the independent setting method of the two areas (411 and 412) makes the radar module 2 not cause occlusion interference to the radiation of visible light, and the light-emitting component 3 does not cause occlusion interference to the emission and reception of radar waves, ensuring the coordination and cooperation speed of the lighting function and the human body induction function.

[0087] Furthermore, as Figure 3 shown, the positional relationship between the lamp housing 1, the light-emitting component 3, and the radar module 2 is presented, where Figure 3 the radar hiding part 4 is not shown in Figure 3 The light-emitting component 3 and the radar module 2 in

[0088] Furthermore, as Figure 1 and Figure 2As shown, one side of the lamp housing 1 is open, and a radar concealment member 4 is provided on the open side of the lamp housing 1. The radar concealment member 4 is provided with a first light-emitting hole 413, and the light emitted by the light-emitting component 3 is emitted outward through the first light-emitting hole 413 to form the first area 411 within the range of the first light-emitting hole 413; the radar module 2 is concealed inside the radar concealment member 4 (that is, the radar module 2 is concealedly arranged inside the radar concealment member 4), and the radar waves emitted by the radar module 2 pass through the radar concealment member 4 and are emitted outward to form the second area 412 on the radar concealment member 4. Wherein, the radar concealment member 4 can be a single part or a combination of multiple parts, and the inner side of the radar concealment member 4 can be understood as the side facing the inside of the lamp housing 1. The first area 411 can be a part of the area within the first light-emitting hole 413 or the entire area within the first light-emitting hole 413. In one embodiment, as Figure 1 shown, the first area 411 is only a part of the area within the first light-emitting hole 413. It can be understood that in some feasible embodiments, the radar module 2 can be directly installed on the radar concealment member 4 or installed on other structures, as long as the radar module 2 is limited inside the radar concealment member 4, it is within the protection scope of the present invention.

[0089] The present invention utilizes the penetrability of radar waves to conceal the radar module 2 inside the radar concealment member 4, and the radar waves pass through the radar concealment member 4 and are emitted outward. While ensuring the working performance of the radar module 2, the exposure of the radar module 2 is avoided. The light-emitting component 3 radiates visible light outward through the first light-emitting hole 413, ensuring that the intensity of the radiated visible light meets the requirements. At the same time, restricting the first area 411 within the range of the first light-emitting hole 413 enables the radar concealment member 4 to have sufficient space to set the radar module 2, allowing the radar module 2 and the light-emitting component 3 to be jointly integrated inside the lamp housing 1.

[0090] Compared with an infrared sensor, the radar module 2 adopted in the present invention can sense a stationary human body, improving the sensing sensitivity. In addition, it has the following advantages: The infrared sensor needs to open a hole in the radar concealment member 4 to let the Fresnel lens of the infrared sensor protrude, which will damage the integrity of the human body induction spotlight 100. The radar module 2 adopted in the embodiment of the present invention is perfectly concealed on the back of the radar concealment member 4, retaining the integrity of the human body induction spotlight 100.

[0091] Furthermore, the radar concealment member 4 is made of an opaque non-metallic material, so that it can not only conceal the radar module 2, but also will not cause shielding to the radar waves. In an exemplary embodiment, the radar concealment member 4 is made of a white plastic material.

[0092] Furthermore, as Figures 1 - 3As shown, the radar concealment member 4 includes a circular concealment plate 41. The first light-emitting hole 413 is opened in the central area of the concealment plate 41. The area of the concealment plate 41 other than the first light-emitting hole 413 is set as the radar arrangement area. The aperture of the first light-emitting hole 413 is less than 40% of the diameter of the concealment plate 41, so that the radar module 2 can be arranged in the radar arrangement area. That is, by controlling the aperture of the first light-emitting hole 413, enough space is left in the radar concealment member 4 to arrange the radar module 2, avoiding interference between the radar module 2 and the light-emitting component 3, and at the same time avoiding the radar module 2 being too close to the side wall of the lamp housing 1, resulting in the radar wave being blocked by the metal lamp housing 1, ensuring that the sensing range of the radar module 2 meets the requirements.

[0093] Among them, the radar module 2 being arranged in the radar arrangement area can be understood as the radar module 2 being arranged in the space directly below the radar arrangement area, that is, the projection pattern generated by the radar module 2 in the vertical direction does not exceed the radar arrangement area. The concealment plate 41 can be understood as a plate-like structure, including a flat plate, a curved plate, etc. The central area of the concealment plate 41 can be understood as an area near the center position of the concealment plate 41, that is, the first light-emitting hole 413 can be located at the exact center position of the concealment plate 41, or at a position deviating from the center but close to the center of the concealment plate 41, so that the light-emitting component 3 and the radar module 2 can be arranged side by side. In one embodiment, the first light-emitting hole 413 is arranged at the exact center position of the concealment plate 41.

[0094] In one embodiment, the aperture of the first light-emitting hole 413 is equal to 24% of the diameter of the concealment plate 41, so that there is more sufficient space on the back of the radar concealment member 4 to arrange the radar module 2, and at the same time making it difficult for the radar wave to be blocked by the lamp housing 1.

[0095] Furthermore, as Figure 4 shown, the radar module 2 is horizontally installed so that the sensing direction of the radar module 2 is the same as the irradiation direction of the light-emitting component 3. Furthermore, the sensing range can cover the illumination range. When the user approaches the illumination area from different directions, the radar module 2 can sense in time and control the light-emitting component 3 to light up.

[0096] In some embodiments, as Figure 4As shown, the sensing range of the radar module 2 forms a sensing angle in the vertical direction, and the beam angle of the human body sensing spotlight 100 is smaller than the sensing angle of the radar module 2, so that the sensing range can cover the lighting range. Among them, the sensing range can be understood as the range within the three-dimensional space where the radar module 2 can sense a human body. The sensing range is approximately conical, and the sensing angle can be understood as the apex angle of the cone in the vertical direction. The lighting range can be understood as the three-dimensional space range formed by the light emitted from the second light-emitting hole 361. In the embodiment of the present invention, covering the sensing range with the lighting range enables the user to turn on the light-emitting component 3 in advance before entering the lighting range, improving the user experience. Specifically, when the user enters the sensing range but not the lighting range, the radar module 2 has already sensed the user, thereby controlling the light-emitting component 3 to turn on. In a specific embodiment, the sensing angle is 130°, and the beam angle is 50°.

[0097] As can be seen Figure 4 from, the thickness required for the radar wave to vertically pass through the hidden plate 41 is less than the thickness required for the radar wave to obliquely pass through the hidden plate 41. When the central depression amplitude of the hidden plate 41 is large, the thickness required for the radar wave to pass through the hidden plate 41 to the right increases significantly, resulting in a reduction in the sensing range on the right side of the human body sensing spotlight 100. Correspondingly, the thickness required for the radar wave to pass through the hidden plate 41 to the left decreases, and the sensing range on the left side increases, so that the overall sensing range shifts to the left, resulting in a situation where the sensing range does not correspond to the lighting range, affecting the user experience.

[0098] In one embodiment, to solve the above technical problem, the hidden plate 41 is configured as a flat plate.

[0099] In other embodiments, to solve the above technical problem, the hidden plate 41 is configured as a conical plate with a central depression, and its depression depth is less than 10% of the diameter, forming a slightly depressed effect. Or, the hidden plate 41 is configured as a conical plate with a central protrusion, and its protrusion height is less than 10% of the diameter, forming a slightly protruding effect at the center.

[0100] In the embodiment of the present invention, by controlling the amplitude of the depression / protrusion of the hidden plate 41, the plate thickness of the radar wave passing through the hidden plate 41 is relatively thin, and the thickness change of the radar wave passing through different positions of the hidden plate 41 is small, ensuring that the sensing range of the radar module 2 meets the requirements, and making the sensing range correspond to the lighting range when the radar module 2 is horizontally installed.

[0101] Exemplarily, as Figure 4 shown, the hidden plate 41 is configured as a conical plate with a slightly depressed center. Specifically, for example Figure 4 shown, the hidden plate 41 is configured as a conical plate with a slightly depressed center, and its depression depth is 5% of the diameter.

[0102] In some embodiments, such as Figure 4 and Figure 5 shown, the radar module 2 is installed on the hidden plate 41. It can be seen from Figure 4 that the farther the radar module 2 is from the hidden plate 41, the more the sensing range is blocked, and the smaller the sensing range is. The closer it is to the hidden plate 41, the less the sensing range is blocked, and the larger the sensing range is. In this embodiment, the radar module 2 is directly installed on the hidden plate 41, which is beneficial to shortening the distance between the radar module 2 and the hidden plate 41, so that the sensing range is large enough. In addition, directly installing the radar module 2 on the hidden plate 41 is beneficial to ensuring the installation accuracy and levelness of the radar module 2.

[0103] In some embodiments, such as Figure 5 shown, the radar module 2 includes a radar circuit board 21. At least two mounting holes 211 are formed in the radar circuit board 21. Mounting posts 42 extend from the back surface of the hidden plate 41 at positions corresponding to the mounting holes 211. The mounting posts 42 are inserted into the mounting holes 211 so that the radar circuit board 21 is positioned in the horizontal direction. A positioning step 43 is provided at the root of the mounting post 42. The radar circuit board 21 abuts against the positioning step 43 so that the radar circuit board 21 is positioned in the vertical direction. Among them, the hidden plate 41 realizes the precise positioning of the radar circuit board 21 through the mounting posts 42 and the positioning steps 43, ensuring the installation accuracy of the radar module 2, and the installation method is relatively convenient, which is beneficial to improving the assembly efficiency.

[0104] In one embodiment, three mounting holes 211 are formed in the radar circuit board 21. The three mounting holes 211 are respectively located at three right angles of the radar circuit board 21. The hidden plate 41 is provided with three mounting posts 42. The three mounting posts 42 are correspondingly inserted into the mounting holes 211 respectively to improve the positioning accuracy of the radar circuit board 21 in the horizontal direction. The hidden plate 41 is respectively provided with the positioning steps 43 at the four right angles of the radar circuit board 21. The radar circuit board 21 abuts against each positioning step 43 to improve the positioning accuracy of the radar circuit board 21 in the vertical direction. Each positioning step 43 includes four positioning ribs 126. The four positioning ribs 126 are arranged around the mounting post 42. The positioning ribs 126 can not only realize the vertical positioning of the radar circuit board 21, but also strengthen the strength of the mounting post 42 and ensure the verticality of the mounting post 42.

[0105] Furthermore, the mounting post 42 is fixedly connected to the radar circuit board 21. The fixed connection method can be hot melt fixing, dispensing fixing, snap connection fixing, etc. In one embodiment, such as Figure 8As shown, after the radar circuit board 21 abuts against the positioning step 43, glue is applied at the connection part of each mounting post 42 and the mounting hole 211 to realize the fixed connection between the mounting post 42 and the radar circuit board 21. In another embodiment, as Figure 10 shown, after the radar circuit board 21 abuts against the positioning step 43, the ends of the mounting posts 42 are hot-melted and flattened, and the flattened mounting posts 42 and the positioning step 43 clamp and fix the radar circuit board 21.

[0106] Furthermore, as Figure 3 and Figure 6 shown, the radar module 2 includes a radar circuit board 21, a transmitting antenna 22 and a receiving antenna 23 disposed on the first surface of the radar circuit board 21, and the first surface is set to be the side of the radar circuit board 21 facing the radar hiding member 4. Among them, the transmitting antenna 22 includes a first copper sheet, the receiving antenna 23 includes a second copper sheet, and both the first copper sheet and the second copper sheet are laid on the first surface. The transmitting antenna 22 emits radar waves externally at regular time intervals. The radar waves are reflected back when they encounter a human body or an object in the environment. The receiving antenna 23 receives the reflected radar waves. A radar driving chip 24 is disposed on the side of the radar circuit board 21 facing away from the radar hiding member 4. The power supply module 5 includes a main control unit. The radar driving chip 24 or the main control unit determines whether there is a human body or a moving object within the sensing range based on the Doppler principle, and the main control unit controls the lighting component 3 to light up or go out based on the judgment result.

[0107] Since the heat generated by the lighting component 3 is very large, in order to avoid the temperature of the lighting component 3 being too high, it is necessary to improve the heat dissipation performance of the lamp housing 1. In this embodiment, the lamp housing 1 is made of a metal material, and the heat generated by the lighting component 3 is dissipated through the lamp housing 1. However, the metal material will produce a shielding effect on the radar waves. As can be seen from Figure 4 the closer the radar module 2 is to the side wall of the lamp housing 1, the more the radar waves on the right side are blocked by the side wall of the lamp housing 1, resulting in a reduction in the sensing range on the right side. The farther the radar module 2 is from the side wall of the lamp housing 1, the less the radar waves on the right side are blocked by the side wall of the lamp housing 1, and the sensing range on the right side will expand; the lower the height of the radar module 2, the more the radar waves on the right side are blocked by the side wall of the lamp housing 1, resulting in a reduction in the sensing range on the right side. The higher the height of the radar module 2, the less the radar waves on the right side are blocked by the side wall of the lamp housing 1, and the sensing range on the right side will expand. Based on this, in this embodiment, as Figure 3 and Figure 4 shown, in the horizontal direction, the distance between the receiving antenna 23 and the side wall of the lamp housing 1 ( Figure 3 L1 in Figure 4The distance H1) in it is less than 9 mm, and the first end face is arranged at one end of the lamp housing 1 facing the light-emitting direction. By designing the distance L1 between the receiving antenna and the side wall of the lamp housing, and the distance H1 between the receiving antenna and the first end face, the induction range will not be blocked too much by the lamp housing 1, and the induction range can cover the illumination range. Among them, the first end face is the Figure 4 upper end face of the lamp housing 1 in it. The distance L1 between the receiving antenna 23 and the side wall of the lamp housing 1 can be understood as the vertical distance of the receiving antenna 23 from the side wall of the lamp housing 1 in the horizontal direction.

[0108] In an embodiment, the distance L1 between the receiving antenna 23 and the side wall of the lamp housing 1 is 6.3 mm, and the distance H1 between the receiving antenna 23 and the first end face is 5.6 mm.

[0109] The applicant found that the performance of the radar wave is greatly related to the thickness of the hidden board 41, and the distance between the transmitting antenna 22 and the hidden board 41 also affects the performance of the radar wave. Therefore, in some embodiments, in the vertical direction, the distance between the first surface of the radar circuit board 21 and the hidden board 41 is greater than 0.8 mm and less than 4.5 mm, that is, the minimum distance between the two in the vertical direction is greater than 0.8 mm, and the maximum distance is less than 4.5 mm; to reduce the influence of the inner wall of the hidden board 41 on the radar detection wave. In an embodiment, as Figure 8 shown, the hidden board 41 is a circular board with a central depression. The minimum distance between the first surface and the hidden board 41 in the vertical direction is 1.5 mm, and the maximum distance is 2.9 mm. The hidden board 41 is made of plastic material, and the thickness of the hidden board 41 is greater than 0.6 mm and less than 2.5 mm to ensure the penetration efficiency of the radar wave and reduce the radar wave loss. It is worth mentioning that if the hidden board 41 is too thin, it will cause a shadow of the radar module 2 on the hidden board 41. In this embodiment, the thickness of the hidden board 41 is controlled to be greater than 0.6 mm to avoid the radar module 2 casting a shadow on the hidden board 41. In an embodiment, the thickness of the hidden board 41 is 1.3 mm.

[0110] In an embodiment, the radar module 2 uses a one-transmitting and one-receiving radar module 2 with the model number EDQ15P-Y-01 developed by Yitan Technology Co., Ltd., which has one transmitting antenna 22 and one receiving antenna 23. The radar module 2 uses the 24 GHz band. When detecting human movement, the radar module 2 will emit microwaves (such as millimeter waves). When these signals encounter a moving human body, the frequency of the reflected wave will shift due to the direction of human movement (the frequency increases when approaching and decreases when moving away). By analyzing the frequency difference (Doppler frequency shift) between the reflected signal and the original signal, the movement speed, direction, and / or distance of the human body can be calculated to achieve human detection.

[0111] In some embodiments, such asFigures 6 - 9 As shown, a brightness detector 25 is provided on the radar circuit board 21 facing the hidden board 41. A light guide portion 44 is provided on the hidden board 41 at a position directly opposite to the brightness detector 25. The light guide portion 44 guides the light outside the human body induction spotlight 100 into the brightness detector 25, so that the brightness detector 25 can detect the ambient brightness. This ambient brightness, as the first detection result, can be used in combination with the second detection result of the radar module 2 for characterizing whether there is someone in the environment. The following introduces two possible ways of combined use.

[0112] Method 1: The main control unit (such as an embedded SOC) provided in the power supply module 5 receives the first detection result and the second detection result, and controls the lighting / extinguishing of the spotlight based on a preset brightness threshold (such as 200 lux). Specifically, the main control unit is electrically connected to the radar module 2 and the brightness detector 25 respectively to obtain the first detection result and the second detection result.

[0113] Among them, when the first detection result indicates that the ambient brightness is lower than the brightness threshold and the second detection result indicates that there is someone in the environment, the spotlight is controlled to light up (that is, the light-emitting component 3 is lit). When the first detection result indicates that the ambient brightness is higher than the brightness threshold, regardless of whether the second detection result indicates that there is someone or no one in the environment, the spotlight is controlled to extinguish (that is, the light-emitting component 3 is extinguished).

[0114] In Method 1, all control logics are executed locally on the spotlight, not affected by the network environment, and local execution can ensure the execution speed.

[0115] Furthermore, this brightness threshold supports user customization. The user can modify the brightness threshold through a terminal device that has been pre-associated with the spotlight.

[0116] Method 2: The spotlight receives a network configuration operation to connect to a target network, and reports both the first detection result and the second detection result through the target network, so that the gateway, cloud, and / or terminal device in the target network can determine the control result of the spotlight according to predefined logic rules. There can be one or more of these logic rules. These logic rules are predefined by the user (for example, defined through a terminal device and stored in the cloud). Each logic rule defines the triggering relationship between the logic trigger condition and the control result. When the logic trigger condition is met, the control result will be controlled to execute. Specifically, for example, the cloud receives the detection results reported by the spotlight and determines whether the logic trigger condition is met based on this. If it is met, the control result defined by the logic rule is controlled to execute, otherwise, it is not executed.

[0117] Here, the logical trigger condition in the logical rule is associated with at least one of the first detection result and the second detection result (such as someone in the environment, no one in the environment, the brightness being within a predetermined range, etc.), and the control result at least includes one executable function of the spotlight (such as lighting, extinguishing, adjusting the brightness to a specified value, adjusting the color temperature to a specified value, etc.).

[0118] In the second method, a target network is introduced to implement a richer control logic between the first detection result, the second detection result, and the executable functions of the spotlight.

[0119] In addition, the network configuration operation of the spotlight involved in the above embodiments includes:

[0120] The network configuration operation is used to trigger the spotlight to enter the network configuration mode. In the network configuration mode, the spotlight sends out network configuration messages, and at least some of these network configuration messages carry information characterizing the spotlight (such as the MAC address used to uniquely characterize the spotlight, the factory ID information, etc.), so that external intelligent devices such as terminal devices and gateways can scan the spotlight in the network configuration mode based on the network configuration messages, and then guide the spotlight to join the target network based on a preset network configuration method to complete the network configuration of the spotlight.

[0121] After the network configuration is completed, the spotlight can be connected to the target network, and then communicate with the gateway, terminal device, and / or cloud through the target network.

[0122] Furthermore, after the network configuration is completed, the spotlight can be directly connected to the terminal device to directly receive the control from the terminal device. After the network configuration is completed, the spotlight can also receive control instructions from the network (such as control instructions remotely applied by the terminal device through the cloud), and execute corresponding functions.

[0123] Furthermore, after the network configuration is completed, the spotlight can also report the working status (on / off status, brightness, color temperature, etc.) and / or detection results (the first detection result and / or the second detection result) to the cloud. The terminal device can obtain these working status and / or detection results from the cloud and display them to the user.

[0124] Exemplarily, when the difference in the ambient brightness characterized by the first detection result currently detected by the spotlight compared to the previous time meets the reporting condition (such as the brightness difference between two adjacent times is greater than 10 lux), the first detection result currently detected is reported. The detection results reported by the spotlight multiple times are stored in the cloud as historical records. The user can view the change rule of the ambient brightness from the cloud or this historical record through the terminal device, and can also set the required brightness threshold accordingly.

[0125] In some embodiments, after the power distribution network is completed, the user can send a shutdown instruction through the terminal device, and the shutdown instruction is used to instruct the spotlight to turn off the sensing function of the radar module 2. In this case, the spotlight will not report the second detection result, and thus the logic rules related to the second detection result will not be triggered.

[0126] Further, after receiving the shutdown instruction, the spotlight can maintain the detection of the environment by the radar module 2, and only does not report the second detection result to the target network. When the user directly connects to the spotlight through the terminal device, the second detection result of the radar module 2 can also be viewed.

[0127] Further, after receiving the shutdown instruction, the spotlight can also directly stop the detection of the environment by the radar module 2 based on the shutdown instruction. At this time, the radar module 2 stops working, which can save power consumption.

[0128] Furthermore, to stop the detection of the environment by the radar module 2, for example, the power supply of the radar module 2 can be controlled to cut off the power. Or, for example, the power supply of the radar module 2 can be retained, but the emission of its radar waves can be turned off, so that the radar module 2 can quickly restore the detection ability when needed.

[0129] In some embodiments, the detection sensitivity of the radar module 2 can be changed. For example, the user switches the detection sensitivity between high, medium, and low through the terminal device. Among them, the higher the detection sensitivity, the easier it is to trigger the presence of a person (that is, the second detection result indicates that there is a person in the environment), that is, a smaller human movement can trigger the presence of a person. On the contrary, the lower the detection sensitivity, the greater the human movement required to trigger the presence of a person.

[0130] Further, the detection area of the radar module 2 is divided into multiple continuous spatial layers, and each spatial layer has a detection sub-sensitivity, which is used to determine the difficulty of triggering the presence of a person in that spatial layer. The detection sub-sensitivities between the spatial layers are independent of each other, that is, the user can independently set the detection sub-sensitivity of any spatial layer, so that the detection sub-sensitivities of the spatial layers change according to the user's needs. Among them, the range of the detection sub-sensitivity can be 0 to 100. The larger the value, the higher the sensitivity and the easier it is to trigger the presence of a person, and vice versa. When the detection sub-sensitivity is set to 0, the corresponding spatial layer will not be triggered to detect the presence of a person. Correspondingly, when the detection sub-sensitivity is set to 100, the corresponding spatial layer will always be in the state of triggering the presence of a person.

[0131] In a possible application scenario, for example, if the detection area of the radar module 2 can cover a range of 6 meters (taking the spotlight as the reference, as the distance 0 point), then with a height of 0.75 meters as the height of the space layer, the 6-meter range is divided into 8 space layers. After the spotlight is installed on the ceiling, it will cover a detection range of about 3 meters in the vertical direction, and this detection range includes four space layers (0 - 0.75m, 0.75 - 1.5m, 1.5 - 2.25m, 2.25 - 3m). Users can set the detection sub-sensitivity of the space layer of 2.25 - 3m to 0 to shield the human detection function of this space layer. In this way, when pets such as cats and dogs with a height within 0.75m walk on the ground, it will not trigger the detection of a person, thus preventing false triggers by pets.

[0132] Furthermore, users can also change the trigger conditions of the second detection result according to their needs. Specifically, the spotlight (specifically, for example, the main control unit of the spotlight) receives a switching instruction, which is generated by the user's alternative selection of different trigger modes of the spotlight on the terminal device. Each trigger mode has a trigger parameter, and the trigger parameters between different trigger modes are different. The value range of the trigger parameter is 1 - 3.

[0133] The spotlight uses the radar module 2 to detect whether there is anyone in the environment, obtains the detection results of whether there is anyone in each space layer, and determines whether there are more than a set number of adjacent space layers triggered as having someone; if so, it is determined that there is someone; otherwise, it is determined that there is no one. This set number is determined according to the trigger parameter, thereby realizing the setting of the trigger conditions of the radar module 2 based on the switching instruction.

[0134] In some embodiments, the brightness detection component 25 can be a photoresistor or other electronic components capable of detecting brightness. In one embodiment, the brightness detection component 25 is a photoresistor. Further, the light guiding part 44 is directly opposite to the photosensitive part of the photoresistor to make the brightness detection more accurate. The light guiding part 44 can be a light guiding hole, a light guiding wall, a light guiding column or other structures capable of guiding light.

[0135] Further, as Figure 8 and Figure 5 shown, the light guiding part 44 includes a light guiding hole 441 and an annular reflective wall 442 extending from the periphery of the light guiding hole 441 towards the radar circuit board 21. The annular reflective wall 442 surrounds the brightness detection component 25, and a reflective cavity 443 is formed inside the annular reflective wall 442. A part of the ambient light introduced by the light guiding hole 441 is reflected and mixed in the reflective cavity 443 and then irradiates the brightness detection component 25, thereby improving the accuracy of brightness detection. Further, the annular reflective wall 442 is white to improve the light reflection performance of the reflective cavity 443.

[0136] In another embodiment, as Figure 9As shown, a light guide column 444 is embedded in the light guide hole 441. The light guide column 444 closes the light guide hole 441. The light guide column 444 is arranged directly above the brightness detection member 25, and ambient light is conducted to the brightness detection member 25 through the light guide column 444. The light guide column 444 is injection molded using polymethyl methacrylate (PMMA) or polycarbonate (PC) to improve the light guiding performance.

[0137] In the prior art, the brightness detection member 25 generally only functions when the lamp is not lit. Its function is to control the lamp not to light up when the ambient brightness is too high; after the lamp is lit, the light propagates inside the lamp to the brightness detection member 25, and the data detected by the brightness detection member 25 is no longer of reference value, and the user cannot intuitively obtain the change in ambient light brightness after the lamp is lit. To solve this problem, in this embodiment, as Figure 8 shown, the annular reflecting wall 442 not only has the function of reflecting ambient light, but also can reduce the interference of the light emitted by the light emitting component 3 on the brightness detection member 25, blocking the light emitted by the light emitting component 3 from propagating to the brightness detection member 25, so that in the lit state, the brightness detection member 25 can relatively accurately detect the ambient light, and thus feedback a more valuable ambient brightness value to the user, enabling the user to clearly and intuitively obtain the ambient brightness changes in the lit and unlit situations.

[0138] In some embodiments, as Figure 2 shown, a first cavity 13 is formed between the radar hiding member 4 and the lamp housing 1. The light emitting component 3 is arranged inside the first cavity 13; a light transmission cavity 31 for propagating light is provided inside the light emitting component 3, and the light emitting end of the light transmission cavity 31 faces the first light emitting hole 413 of the radar hiding member 4; the radar module 2 is located inside the first cavity 13 and outside the light transmission cavity 31. Among them, the light emitting end facing the first light emitting hole 413 can be understood as that the light emitting end is directly below the first light emitting hole 413 or the light emitting end is embedded inside the first light emitting hole 413, so that the light emitted from the light emitting end directly emits from the first light emitting hole 413. Most of the light generated by the light emitting component 3 propagates in the light transmission cavity 31, and the light emitted from the light transmission cavity 31 is directly emitted outward through the first light emitting hole 413. Only a small amount of light enters the sandwich space between the first cavity 13 and the light transmission cavity 31. The radar module 2 is arranged in the sandwich space between the first cavity 13 and the light transmission cavity 31, reducing the light propagation inside the lamp housing 1 to the brightness detection member 25, enabling the brightness detection member 25 to more accurately detect the ambient brightness when the lamp is lit. Moreover, since only a small amount of light enters the sandwich space between the first cavity 13 and the light transmission cavity 31, it prevents the sandwich space from being too bright and causing the light to penetrate through the hiding plate 41, thereby avoiding the radar module 2 casting a shadow on the hiding plate 41.

[0139] Furthermore, asFigure 2 As shown, the light-emitting component 3 further includes a light-emitting element 32 and a condenser lens 34. A second light-emitting hole 361 is provided at the light-emitting end of the light-transmitting cavity 31 at a position directly opposite to the first light-emitting hole 413. The light-emitting element 32 is disposed at the light-incident end of the light-transmitting cavity 31, and the condenser lens 34 is disposed inside the light-transmitting cavity 31 and is located between the light-emitting element 32 and the second light-emitting hole 361. The condenser lens 34 converges the light emitted by the light-emitting element 32 and then emits it outwards through the second light-emitting hole 361 and the first light-emitting hole 413. Among them, the light-emitting element 32 can be understood as a module or electronic component with a light-emitting function. In one embodiment, the light-emitting element 32 includes an LED lamp bead 322 and a light-emitting circuit board 321 carrying the LED lamp bead 322. Figure 14 It is a schematic diagram of the light path when the light-emitting element 32 emits light at the central position. Among them, the light path shown in the figure is only for illustration and is not used as a reference for the actual light path. The light converges towards the second light-emitting hole 361 through the condenser lens 34. The convergence points can be dispersed below, above the second light-emitting hole 361 or at the same height as the second light-emitting hole 361. As long as the light is converged near the second light-emitting hole 361, most of the light can be emitted from the second light-emitting hole 361 to reduce the brightness loss. The light that is not converged to the second light-emitting hole 361 can be understood as stray light. Most of the stray light is blocked inside the light-transmitting cavity 31, thereby weakening the dazzling effect caused by the stray light.

[0140] In some embodiments, such as Figures 14 - 16 As shown, the condenser lens 34 is configured as a rotating body, and an incident light concave cavity is provided at the bottom thereof. The opening of the incident light concave cavity faces the LED lamp bead 322 directly. Most of the light emitted by the LED lamp bead 322 enters the incident light concave cavity and enters the inside of the condenser lens 34 through refraction in the incident light concave cavity. The side surface of the condenser lens 34 is a total reflection surface, and total reflection occurs when the light irradiates the side surface of the condenser lens 34 from the inside of the condenser lens 34. An outgoing light surface 342 is provided at the top of the condenser lens 34, and the light that has undergone total reflection is refracted out from the outgoing light surface 342.

[0141] The material of the condenser lens 34 can be PMMA, PC or resin. In a preferred embodiment, the condenser lens 34 is integrally injection-molded using PC material.

[0142] Furthermore, as shown in Figure 15 and Figure 13As shown, a light-shielding ring 362 extends towards the light-emitting direction along the periphery of the second light-emitting hole 361 of the light-emitting component 3. The radar concealment member 4 abuts against the light-emitting component 3, and the light-shielding ring 362 is embedded in the first light-emitting hole 413 to prevent light from irradiating into the interlayer space through the gap between the first light-emitting hole 413 and the second light-emitting hole 361, reducing the light from propagating inside the lamp housing 1 to the brightness detection member 25, so that the brightness detection member 25 can more accurately detect the ambient brightness when the lamp is on. At the same time, the light-shielding ring 362 is embedded in the first light-emitting hole 413, so that the light-shielding ring 362 is radially positioned, thereby improving the position accuracy and verticality of the light-emitting component 3 and preventing the light-emitting component 3 from tilting.

[0143] Further, the inner side wall of the light-shielding ring 362 and the side wall of the second light-emitting hole 361 are integrally formed to form a hole in the shape of a flared mouth, and its aperture gradually expands towards the light-emitting side.

[0144] In some embodiments, as Figure 12 and Figure 13 shown, the light-emitting component 3 further includes a limiting member 33, a lens housing 35, and an anti-glare cover 36 arranged in sequence along a first direction. The first direction is the direction in which the light-emitting member 32 faces the second light-emitting hole 361, and the first direction has been marked in Figure 13 . A partition plate 121 is provided on the side of the first cavity 13 away from the radar concealment member 4. As Figure 17 shown, the limiting member 33 limits the light-emitting member 32 to the partition plate 121, so that the heat generated by the light-emitting member 32 is conducted to the side wall of the lamp housing 1 through the partition plate 121 and dissipated through the side wall of the lamp housing 1. Among them, the partition plate 121, the side wall of the lamp housing 1, and the hidden plate 41 enclose to form the first cavity 13. An insulating pad 8 made of plastic is provided between the light-emitting circuit board 321 and the partition plate 121. The lower surface of the light-emitting circuit board 321 is attached to the upper surface of the insulating pad 8, and the lower surface of the insulating pad 8 is attached to the partition plate 121. A heat-conducting silicone grease is applied between the light-emitting circuit board 321, the insulating pad 8, and the partition plate 121. The heat generated by the light-emitting member 32 is conducted to the side wall of the lamp housing 1 through the insulating pad 8 and the partition plate 121 and dissipated through the side wall of the lamp housing 1.

[0145] As Figure 17As shown, the light-emitting circuit board 321 is configured as a square circuit board. The LED lamp beads 322 are arranged at the center of the light-emitting circuit board 321. A first welding point is provided at a right angle of the light-emitting circuit board 321, and a second welding point and a third welding point are provided at the other right angle opposite to this right angle. The light-emitting circuit board 321 is connected to the power supply module 5 through three second wires 38, and the three second wires 38 are respectively welded to the first welding point, the second welding point, and the third welding point. The partition board 121 is provided with second wire holes 123 for the second wires 38 to pass through.

[0146] Since the lamp housing 1 is made of a metal material, the function of the insulating pad 8 is to improve the insulation performance between the light-emitting circuit board 321 and the partition board 121, and to improve the insulation performance between the first welding point, the second welding point, and the third welding point and the partition board 121, so as to avoid the lamp housing 1 being charged.

[0147] The limiting member 33 is fixedly connected to the partition board 121 by two connecting screws 127. The insulating pad 8 is provided with screw through holes at positions corresponding to the connecting screws 127. The connecting screws 127 pass through the screw through holes and are connected to the partition board 121. The light-emitting circuit board 321 and the insulating pad 8 are clamped between the limiting member 33 and the partition board 121. A lamp bead receiving hole 331 is provided at the center of the limiting member 33. The LED lamp beads 322 are received in the lamp bead receiving hole 331. The side wall of the lamp bead receiving hole 331 can block the light emitted laterally by the LED lamp beads 322, reducing the light entering the interlayer space. As Figure 13 and Figure 16 shown, an annular light-blocking wall 332 extends upward around the outer edge of the limiting member 33. The bottom of the lens housing 35 is embedded inside the annular light-blocking wall 332. The side wall of the lens housing 35 and the annular light-blocking wall 332 form an upper and lower staggered light-blocking structure, which can further block the light from entering the interlayer space, ensuring that the brightness detection member 25 can more accurately detect the ambient brightness when the lamp is on. At the same time, as Figure 17 shown, the annular light-blocking wall 332 also has a wire pressing function, and can clamp the second wire 38 between the annular light-blocking wall 332 and the partition board 121.

[0148] Furthermore, as Figure 16 and Figure 15As shown, one end of the lens housing 35 is snap-connected to the limiting member 33, and the other end is sleeved by the anti-glare cover 36; both the lens housing 35 and the anti-glare cover 36 are hollow housings, and the hollow parts of the two together form the light transmission cavity 31; a second light outlet hole 361 is opened at one end of the anti-glare cover 36 away from the condenser lens 34, and the light shielding ring 362 is integrally formed on the anti-glare cover 36; the lens housing 35 surrounds the side surface of the condenser lens 34 and positions the condenser lens 34. Among them, the lens housing 35 surrounding the side surface of the condenser lens 34 can prevent light from emitting from the side surface of the condenser lens 34 to block light from entering the interlayer space.

[0149] Further, as Figure 15 and Figure 16 shown, a snap ring 341 extends outward from the upper end side surface of the condenser lens 34. The snap ring 341 surrounds the side surface of the condenser lens 34 for one week. Snap protrusions 351 are respectively arranged on both sides of the upper end of the lens housing 35, and a positioning ring surface 352 is arranged at the upper end of the lens housing 35. The lower surface of the snap ring 341 of the condenser lens 34 abuts against the positioning ring surface 352, and the snap protrusions 351 are snap-connected to the upper surface of the snap ring 341, so that the snap ring 341 is clamped between the positioning ring surface 352 and the snap protrusions 351 to realize the snap connection and fixation between the lens housing 35 and the condenser lens 34. The side wall of the lens housing 35 abuts against the side surface of the condenser lens 34 to realize radial positioning between the two, thereby improving the position accuracy of the condenser lens 34.

[0150] Further, as Figure 15 shown, a socket ring 363 extends downward for one week on the side surface of the anti-glare cover 36. The socket ring 363 is sleeved on the upper edge of the lens housing 35 to realize radial positioning between the socket ring 363 and the lens housing 35. The width of the socket ring 363 extending downward is relatively wide, so that the socket ring 363 not only has a socket limiting function but also has a light shielding function, and can block light from entering the interlayer space.

[0151] Further, as Figure 16 shown, support feet 353 are arranged at the bottom of the lens housing 35. The support feet 353 abut against the limiting member 33 to realize vertical positioning between the lens housing 35 and the limiting member 33. Vertical hooks 354 extend downward from both sides of the lens housing 35, and the limiting member 33 is provided with snap holes 333. The two vertical hooks 354 are respectively snap-connected to the snap holes 333 to realize radial positioning and snap connection and fixation between the lens housing 35 and the limiting member 33.

[0152] In some embodiments, the lens housing 35 and the anti-glare cover 36 are both made of black plastic material to improve the performance of the anti-glare cover 36 in absorbing stray light, enhance the anti-glare effect, and reduce the light transmission performance of the lens housing 35 and the anti-glare cover 36, reducing the light entering the sandwich space from the light transmission cavity 31, ensuring that the brightness detection member 25 can more accurately detect the ambient brightness when the light is on.

[0153] In some embodiments, as Figure 15 shown, the condenser lens 34 has a light-emitting surface 342, and an anti-glare cavity 37 is provided between the light-emitting surface 342 and the second light-emitting hole 361. The light emitted from the light-emitting surface 342 is emitted outward by the second light-emitting hole 361 after passing through the anti-glare cavity 37. Among them, the anti-glare cavity 37 can be understood as the upper half of the light transmission cavity 31. The function of the anti-glare cavity 37 is to absorb stray light, and the stray light can be understood as the light emitted from the light-emitting surface 342 but not converged to the second light-emitting hole 361. The stray light is reflected multiple times in the anti-glare cavity 37, and finally most of it is absorbed by the inner wall of the anti-glare cavity 37, thereby weakening the dazzling effect caused by the stray light. Moreover, most of the stray light is eliminated, making the light emitted from the second light-emitting hole 361 more regular, and presenting a "small hill" shape when the light hits the wall parallelly.

[0154] As Figure 13 shown, the length of the anti-glare cavity 37 in the first direction ( Figure 13 L2 in Figure 13 ) is greater than 0.6 times the aperture diameter ( Figure 13 ΦA in

[0155] ) of the second light-emitting hole 361, so that the light-emitting surface 342 is far enough from the second light-emitting hole 361, and the stray light is not easily emitted from the second light-emitting hole 361, and the anti-glare effect of the anti-glare cavity 37 is better. The first direction is the direction in which the light-emitting surface 342 faces the light-emitting hole. In one embodiment, the length of the anti-glare cavity 37 in the first direction is equal to 0.93 times the aperture diameter of the second light-emitting hole 361.

[0155] Furthermore, as Figure 12 shown, one end of the lamp housing 1 facing the first direction has a first end face, and the aperture diameter ΦA of the second light-emitting hole 361 is less than 1 / 4 of the outer diameter ΦC of the first end face. Among them, in the embodiments of the present invention, by controlling the aperture diameter of the second light-emitting hole 361, less stray light is emitted from the second light-emitting hole 361, thereby improving the anti-glare effect; and making the light emitted from the second light-emitting hole 361 more regular, and presenting a "small hill" shape when the light hits the wall parallelly. In one embodiment, the aperture diameter ΦA of the second light-emitting hole 361 is equal to 0.16 times the outer diameter ΦC of the first end face.

[0156] In some embodiments, as Figure 13As shown, the anti-glare cavity 37 is configured as a cylindrical cavity, and the aperture ΦA of the second light-emitting hole 361 is smaller than the diameter ΦB of the anti-glare cavity 37, so that the second light-emitting hole 361 forms a constricted opening relative to the anti-glare cavity 37, making it more difficult for stray light to emit from the second light-emitting hole 361 and achieving a better anti-glare effect. In an embodiment, the aperture ΦA of the second light-emitting hole 361 is equal to 13.5 mm, and the diameter ΦB of the anti-glare cavity 37 is equal to 22 mm.

[0157] Further, as Figure 15 shown, the condenser lens 34 includes an incident end and an exit end. The light-emitting member 32 is disposed at the incident end, and the end face of the exit end constitutes the light-emitting surface 342. The anti-glare cover 36 is sleeved on the exit end of the condenser lens 34 to form the anti-glare cavity 37 between the anti-glare cover 36 and the light-emitting surface 342; the second light-emitting hole 361 is opened at one end of the anti-glare cover 36 away from the condenser lens 34.

[0158] Further, as Figure 10 shown, it is a schematic diagram of the overall structure of the human body induction spotlight 100. One end of the lamp housing 1 facing the light-emitting direction extends radially outward to form an abutting wall 112. The abutting wall 112 surrounds the lamp housing 1 for one week, and the upper surface of the abutting wall 112 is the first end face. Mounting arms 113 are respectively riveted and fixed on both sides of the side wall of the lamp housing 1. The mounting arms 113 extend in a direction away from the abutting wall 112 and are inclined outward. The human body induction spotlight 100 is installed in a ceiling hole opened in the ceiling board, and the irradiation direction of the lamp housing 1 is vertically downward. The mounting arms 113 have elasticity. When the human body induction spotlight 100 is installed, the installer first squeezes and contracts the mounting arms 113 radially, and then installs them into the ceiling hole from bottom to top. The abutting wall 112 abuts against the lower surface of the ceiling board, and the mounting arms 113 bounce to both sides after entering the ceiling hole, so that the mounting arms 113 are clamped in the ceiling hole, thereby realizing the snap connection and fixation of the first housing 11 and the ceiling board. Further, the mounting arms 113 are formed by cutting and bending an iron sheet, and a plastic sleeve is sleeved on the end of the mounting arms 113 to facilitate user operation.

[0159] In some embodiments, as Figures 11 - 12 shown, the human body induction spotlight 100 is internally integrated with a power supply module 5, so that there is no need for an external power supply to drive, and the installation is more convenient. Moreover, the power supply module 5 and the radar module 2 are integrated inside the human body induction spotlight 100 and are directly connected to each other, making the signal transmission more stable.

[0160] Further, the human body induction spotlight 100 includes a power supply module 5 and a power supply housing 6 disposed outside the first cavity 13. The lamp housing 1 is provided with a partition plate 121 between the power supply module 5 and the first cavity 13. The power supply housing 6 is connected to the partition plate 121, and a second cavity 61 is formed between the power supply housing 6 and the partition plate 121. The power supply module 5 is disposed inside the second cavity 61; the radar module 2 and the light emitting component 3 are respectively electrically connected to the power supply module 5.

[0161] In some embodiments, as Figure 12 shown, the radar module 2 includes a radar circuit board 21, the power supply module 5 includes a power supply board 51, and the radar circuit board 21 is connected to the power supply board 51 through a plurality of first wires 7; the light emitting element 32 is connected to the power supply board 51 through a plurality of second wires 38; the partition plate 121 is provided with a first wire hole 122 and a second wire hole 123, the first wire 7 passes through the first wire hole 122, and the second wire 38 passes through the second wire hole 123. Among them, the power supply board 51 controls the brightness of the LED lamp beads 322 through the second wire 38. In one embodiment, as Figure 17 shown, the LED lamp beads 322 are two-color temperature LED lamp beads 322, the number of the second wires 38 is three, a lighting driving unit is arranged on the power supply board 51, the lighting driving unit is electrically connected to the second wire 38, and the lighting driving unit controls the LED lamp beads 322 through the second wire 38 to adjust the brightness and color temperature.

[0162] Further, as Figure 22 shown, a wiring terminal 71 is arranged at the end of the first wire 7, and the power supply board 51 is provided with a plug-in port 52. The wiring terminal 71 is plugged into the plug-in port 52 to realize the conduction between the first wire 7 and the power supply board 51. Among them, Figure 22 the other electronic components except the power supply board 51 and the plug-in port 52 in the power supply module 5 are hidden. The length of the first wire 7 shown in the figure is only for illustration and does not represent the actual length. In one embodiment, the number of the first wires 7 is four, and four first welding holes 212 are formed at positions close to the edge of the radar circuit board 21. One end of the first wire 7 is inserted into the first welding hole 212 and welded and fixed. The other end of the first wire 7 is connected to the wiring terminal 71. Further, the size of the first wire hole 122 is larger than the size of the wiring terminal 71 in the horizontal direction, so that the wiring terminal 71 can vertically pass through the first wire hole 122.

[0163] Since the lamp housing 1 is made of metal material, in order to improve electrical safety and eliminate the risk of the lamp housing 1 being electrified, in one embodiment, an insulating sleeve (not shown in the drawings) is sleeved outside the four first wires 7. The insulating sleeve wraps the four first wires 7 to improve the insulation performance of the first wires 7 and prevent the first wires 7 from conducting electricity with the lamp housing 1. Each second wire 38 is sleeved with an insulating sleeve (not shown in the drawings) to improve the insulation performance of the second wire 38 and prevent the second wire 38 from conducting electricity with the lamp housing 1.

[0164] The structure of the power supply module 5 is as Figure 20 and Figure 21 shown. The power supply module 5 includes a power supply board 51 and electronic components arranged on the power supply board 51. The power supply board 51 carries a strong electricity circuit and a weak electricity circuit. The power supply module 5 converts household alternating current into weak electricity to provide electrical energy for the weak electricity circuit and the light-emitting component 32. Among them, in Figure 20 and Figure 21 , only a part of the electronic components are shown on the power supply board 51, and not all the electronic components are shown.

[0165] As Figure 20 and Figure 17 shown, three second welding holes 511 are arranged at one end of the power supply board 51 close to the edge. One end of each of the three second wires 38 is welded to the three second welding holes 511 respectively, and the other ends are welded to the first welding point, the second welding point and the third welding point of the light-emitting circuit board 321 respectively.

[0166] As Figure 20 and Figure 23 shown, two third welding holes 512 are arranged at one end of the power supply board 51 far from the second welding holes 511. A wire passing through hole is formed in the side wall of the power supply housing 6. The power cord 62 passes through the wire passing through hole from the outside of the power supply housing 6 into the inside of the power supply housing 6. The power cord 62 is divided into a zero wire and a live wire inside the power supply housing 6, and the zero wire and the live wire are welded to the two third welding holes 512 respectively. A rubber anti-disengagement head 621 is arranged on the inner side of the power supply housing 6 for the power cord 62. The size of the rubber anti-disengagement head 621 is larger than the size of the wire passing through hole to prevent the power cord 62 from disengaging from the power supply housing 6 outward; anti-disengagement buckles 63 are arranged on both sides of the rubber anti-disengagement head 621 of the power supply housing 6, and the anti-disengagement buckles 63 are clamped on both sides of the rubber anti-disengagement head 621 to fix the rubber anti-disengagement head 621.

[0167] Further, as Figure 21 , Figure 18 and Figure 23As shown, the power supply board 51 is provided with two second connection holes 513. The power supply housing 6 is provided with second connection posts 64 at positions corresponding to the second connection holes 513. The second connection posts abut against the lower surface of the power supply board 51. The second screws 641 pass through the second connection holes 513 and are connected to the second connection posts 64, so that the power supply board 51 is fixedly connected to the power supply housing 6. It should be noted that the two second connection holes 513 are respectively arranged at positions near the edges at both ends of the power supply board 51, so that the distance between the two second connection holes 513 is relatively large, improving the positioning accuracy of the power supply board 51 in the horizontal direction.

[0168] Further, as Figures 17 - 19 shown, the partition board 121 is provided with two first connection holes 124. The power supply housing 6 is provided with first connection posts 65 at positions corresponding to the first connection holes 124. The first screws 651 pass through the first connection holes 124 and are connected to the first connection posts 65 to realize the fixed connection between the partition board 121 and the power supply housing 6. Further, an arc-shaped positioning wall 125 extends from the side surface of the lamp housing 1 towards the power supply housing 6. The arc-shaped positioning wall 125 surrounds the side surface of the power supply housing 6 and is used for the radial positioning of the power supply housing 6. A positioning groove 66 is provided at the opening end of the side wall of the power supply housing 6. A positioning rib 126 protrudes from the partition board 121 at a position corresponding to the positioning groove 66. The positioning rib 126 is embedded in the positioning groove 66 to realize the circumferential positioning between the power supply housing 6 and the first housing 11. Among them, the mutual positioning of the power supply housing 6 and the lamp housing 1 is to facilitate the accurate screwing of the first screw 651 into the first connection post 65 during the assembly process, improving the assembly efficiency.

[0169] In some embodiments, as Figure 18As shown, the lamp housing 1 includes a first housing 11 and a second housing 12. The first housing 11 and the second housing 12 are coaxially arranged and are connected by threads therebetween. The partition plate 121 is integrally formed on the second housing 12. The radar concealment member 4 is snap-fitted to the first housing 11. The first housing 11, the second housing 12, and the radar concealment member 4 enclose to form the first cavity 13. Both the first housing 11 and the second housing 12 are made of aluminum alloy. Among them, the integral formation of the partition plate 121 on the second housing 12 enables the partition plate 121 to be seamlessly connected to the second housing 12, which is beneficial to better conduction of heat from the partition plate 121 to the second housing 12 and the first housing 11, thereby improving the heat dissipation capacity of the lamp housing 1. And thanks to the excellent heat conduction rate of the aluminum alloy material, the heat dissipation capacity of the lamp housing 1 is further improved. The threaded connection can be understood as that the first housing 11 and the second housing 12 are respectively provided with threads that can cooperate with each other, and the two are locked by relative rotation to achieve a fixed connection therebetween. Further, the arc-shaped positioning wall 125 is integrally formed on the second housing 12.

[0170] It is worth mentioning that the combination of the first housing 11 and the second housing 12 to form the lamp housing 1 makes the assembly more convenient. Specifically, the human body induction spotlight 100 provided by the present invention has a relatively complex assembly. The assembly steps are as follows: Figure 12As shown in the figure, first, the power supply module 5 is fixed inside the power supply housing 6. The anti - detachment rubber head 621 is snapped onto the anti - detachment buckle 63, and the power cord 62 is welded to the power supply board 51. Then, the first wire 7 and the second wire 38 are respectively passed through the partition plate 121. One end of the first wire 7 is welded to the radar circuit board 21, and the other end is plugged into the power supply board 51 through the terminal block 71; one end of the second wire 38 is welded to the power supply board 51, and the other end is welded to the light - emitting part 32. Subsequently, the power supply housing 6 is fixedly installed on the partition plate 121, and the power supply module 5 is sealed inside the second cavity 61. Next, the limiting part 33 is installed on the partition plate 121, and the limiting part 33 limits the light - emitting part 32 on the partition plate 121. The condenser lens 34 is snapped onto the lens housing 35, the lens housing 35 is snapped onto the limiting part 33, and the anti - glare cover 36 is sleeved on the top of the lens housing 35. Next, the first housing 11 is sleeved outside the first wire 7, and the radar circuit board 21 passes through the first housing 11 and is installed on the radar hiding part 4. Finally, the first housing 11 is rotatably connected to the second housing 12, and the radar hiding part 4 is snapped onto the first housing 11, and the assembly is completed. During this installation process, thanks to the lamp housing 1 being composed of the first housing 11 and the second housing 12, during the process of installing the radar circuit board 21 on the radar hiding part 4, the first housing 11 can be kept in an inclined state to reserve more space so that the first wire 7 can install the radar circuit board 21 on the radar hiding part 4 within a limited length, which is beneficial to improving the assembly rate. After the radar circuit board 21 is installed on the radar hiding part 4, the first housing 11 is rotatably connected to the second housing 12.

[0171] Further, as Figure 5 and Figure 4 shown, the radar hiding part 4 includes the hiding plate 41 and four connecting hooks 45 arranged on the back of the hiding plate 41. The four connecting hooks 45 are evenly distributed circumferentially. A clamping groove 111 is arranged around the inner wall of the first housing 11. When the radar hiding part 4 is installed on the first housing 11, the back of the hiding plate 41 abuts against the first housing 11, and the connecting hooks 45 are snapped into the clamping groove 111. Further, to prevent the hiding plate 41 from being disassembled by the user, when installing the hiding plate 41, first brush glue on the connecting hooks 45, and then snap the connecting hooks 45 into the clamping groove 111.

[0172] In some embodiments, the power supply housing 6 is integrally formed of plastic material. A wireless communication module 53 is provided on the power supply board 51. Among them, the use of plastic material for the power supply housing 6 will not produce a shielding effect on the wireless signal to ensure the strength of the wireless signal. As Figure 21 shown, the wireless communication module 53 includes a communication antenna 531. The power supply board 51 is provided with a notch at the position corresponding to the communication antenna 531 to prevent the power supply board 51 from producing a shielding effect on the communication antenna 531, making the wireless signal strength better.

[0173] Furthermore, since the second housing 12 is made of aluminum alloy, the second housing 12 has a shielding effect on wireless signals. In this embodiment, to weaken the shielding effect of the second housing 12, as Figure 19 shown, the arc-shaped positioning wall 125 of the second housing 12 does not surround the whole circumference, but is provided with anti-shielding notches 1251 on both sides. The wireless communication module 53 is arranged at a position corresponding to one of the anti-shielding notches 1251, and wireless signals are sent out from the anti-shielding notches 1251 to weaken the shielding effect of the arc-shaped positioning wall 125. And the communication antenna 531 of the wireless communication module 53 faces outward (as Figure 20 shown), further enhancing the wireless signal strength.

[0174] According to the second aspect of the present invention, there is also provided an intelligent spotlight without a human body sensing function (not shown in the drawings), that is, removing the radar module 4, the light guide part 44, the first wire 7, the terminal 71, the plug-in port 52 and the circuits related to the radar module 4 on the basis of the above-mentioned human body sensing spotlight 100. The intelligent spotlight can receive wireless signals and control the lighting element to turn on or off according to the wireless signals.
