[0078] Generally, the human body sensing device and the spotlight are installed respectively, the spotlight is generally installed on the ceiling panel, if the sensing device controls the spotlight one by one, a plurality of sensing devices need to be set, which brings inconvenience to installation, if one sensing device controls a plurality of spotlights, a series of problems will be caused: the sensing position and the lighting position are inconsistent, which leads to the delay of the spotlight lighting, and the user is too far away from the sensing device to light the nearby spotlight; the sensing device has high requirements for the installation position, if the installation position is improper, the situation of not triggering or false triggering will appear. Therefore, the market urgently needs a spotlight with human body sensing function at present.
[0079] The existing spotlight is difficult to integrate the human body sensing module, the reason is that the human body sensing module needs to be arranged on the light emitting side of the spotlight, so that the human body sensing module senses towards the light emitting direction, and the light emitting side of the existing spotlight is provided with a horn-shaped reflector bowl, the light is emitted outward through the light emitting port of the reflector bowl, the light emitting port occupies most of the area of the light emitting side, so that the human body sensing module cannot be installed on the light emitting side.
[0080] In order to solve the above problems, according to the first aspect of the utility model, a human body sensing spotlight 100 is provided, please refer to Figures 1-23 The human body sensing spotlight 100 provided by the utility model will be specifically explained. Specifically, as Figures 1-3As shown, the human body induction spotlight 100 comprises: a lamp shell 1, one side of which is open; a radar hiding piece 4 arranged at the open side of the lamp shell 1, the radar hiding piece 4 being provided with a first light emitting hole 413; a radar module 2 hidden inside the radar hiding piece 4 (i.e. the radar module 2 is arranged in a hidden manner inside the radar hiding piece 4), radar waves emitted by the radar module 2 being emitted outside through the radar hiding piece 4; and a light emitting assembly 3 arranged inside the lamp shell 1, light emitted by the light emitting assembly 3 being emitted outside through the first light emitting hole 413.
[0081] The lamp shell 1 can be a single shell or a combination of multiple shells. The radar module 2 can be understood as a combination of a radar module, a radar circuit board 21 and other electronic elements on the radar circuit board 21. The radar hiding piece 4 can be a single part or a combination of multiple parts, and the inside of the radar hiding piece 4 can be understood as a side facing the inside of the lamp shell 1. In some possible embodiments, the radar module 2 can be directly mounted on the radar hiding piece 4 or mounted on other structures, as long as the radar module 2 is limited inside the radar hiding piece 4, which is within the protection scope of the present application.
[0082] The radar module 2 and the light emitting assembly 3 are integrated inside the lamp shell 1, so that the spotlight has both lighting and human body induction functions, the user does not need to separately install a human body induction device, and the induction direction does not need to be adjusted, so that the installation convenience is greatly improved.
[0083] Moreover, since the radar wave emission direction and the light emission direction of the light emitting assembly 3 tend to be the same direction, when the user approaches the lighting area, the spotlight can more timely induce the human body, improve the response speed and induction accuracy, and avoid problems such as untimely triggering, not triggering or false triggering of the human body induction spotlight 100.
[0084] The present application utilizes the penetrability of radar waves, hides the radar module 2 inside the radar hiding piece 4, and emits radar waves outside through the radar hiding piece 4, so that the working performance of the radar module 2 is ensured while the radar module 2 is prevented from being exposed outside. The light emitting assembly 3 radiates visible light outside through the first light emitting hole 413, so that the intensity of the radiated visible light meets the requirements.
[0085] The radar module 2 radiates radar waves outside, the radar waves are reflected after being blocked by objects in the environment, the radar module 2 receives the reflected radar waves, and whether there is a human body in the detection range is judged based on the Doppler principle. Compared with an infrared sensor, the radar module 2 has the advantage of being able to sense the subtle movements of a 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, so as to control the light emitting assembly 3 to maintain a lighting state.
[0086] Compared with the infrared sensor, the radar module 2 can sense the static human body, so that the sensing sensitivity is improved. In addition, the infrared sensor needs to be opened on the radar hiding part 4, and the Fresnel lens of the infrared sensor is exposed, which will damage the integrity of the human body sensing spotlight 100. The radar module 2 in the embodiment of the utility model is perfectly hidden at the back of the radar hiding part 4, and the integrity of the human body sensing spotlight 100 is reserved.
[0087] Further, the radar hiding part 4 is made of non-transparent non-metal material, so that it can not only hide the radar module 2, but also will not shield the radar wave. In an exemplary embodiment, the radar hiding part 4 is made of white plastic material.
[0088] Further, as shown in the drawings, Figures 1-3 The radar hiding part 4 includes a circular hiding plate 41, the first light outlet hole 413 is arranged in the center area of the hiding plate 41, and the area of the hiding plate 41 except the first light outlet hole 413 is set as a radar arrangement area. The aperture of the first light outlet hole 413 is less than 40% of the diameter of the hiding 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 outlet hole 413, the radar hiding part 4 has enough space to arrange the radar module 2, so as to integrate the radar module 2 in the lamp shell 1, so that the spotlight can have both lighting and human body sensing functions. At the same time, it avoids that the radar module 2 is too close to the side wall of the lamp shell 1, so that the radar wave is shielded by the metal material of the lamp shell 1, and the sensing range of the radar module 2 meets the requirements.
[0089] The radar module 2 is arranged in the radar arrangement area, which can be understood as that the radar module 2 is arranged in the space directly below the radar arrangement area, that is, the projection figure generated by the vertical projection of the radar module 2 does not exceed the radar arrangement area. The hiding plate 41 can be understood as a plate structure, including a flat plate, a curved plate and the like. The center area of the hiding plate 41 can be understood as a region close to the center position of the hiding plate 41, that is, the first light outlet hole 413 can be located at the center position of the hiding plate 41, or located at a position deviating from the center but close to the center, so that the light emitting assembly 3 and the radar module 2 can be arranged side by side. In an embodiment, the first light outlet hole 413 is arranged at the center position of the hiding plate 41.
[0090] In an embodiment, the aperture of the first light outlet hole 413 is equal to 24% of the diameter of the hiding plate 41, so that there is more enough space at the back of the radar hiding part 4 to arrange the radar module 2, and at the same time, the radar wave is not easy to be shielded by the lamp shell 1.
[0091] In some embodiments, as shown in the drawings, Figure 1As shown, the outer surface of the radar hiding piece 4 forms a radiation area, which includes: a first area 411 for radiating visible light, a second area 412 for radiating radar waves, the light emitted by the light emitting assembly 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 waves emitted by the radar module 2 are emitted outward through the radar hiding piece 4 to form the second area 412 on the radar hiding piece 4, the first area 411 and the second area 412 are independent of each other, so as to integrate the radar module 2 inside the lamp shell 1, and enable the spotlight to have both lighting and human body sensing functions. At the same time, the independent arrangement of the two areas (411 and 412) enables the radar module 2 not to interfere with the radiation of visible light, and the light emitting assembly 3 not to interfere with the emission and reception of radar waves, thereby ensuring the coordination of the lighting function and the human body sensing function.
[0092] Further, as shown in Figure 3 , the positional relationship among the lamp shell 1, the light emitting assembly 3 and the radar module 2 is shown, wherein, Figure 3 The radar hiding piece 4 is not shown in the figure. The light emitting assembly 3 is not in contact with the radar module 2, and the two are arranged side by side in the horizontal direction.
[0093] Further, as shown in Figure 4 , the radar module 2 is horizontally installed, so that the sensing direction of the radar module 2 is consistent with the irradiation direction of the light emitting assembly 3, and thus the sensing range can cover the lighting range, and when a user approaches the lighting area from different directions, the radar module 2 can timely sense and control the light emitting assembly 3 to be lit.
[0094] In some embodiments, as shown in Figure 4 , the sensing range of the radar module 2 forms a sensing included angle in the vertical direction, and the beam angle of the human body sensing spotlight 100 is smaller than the sensing included angle of the radar module 2, so that the sensing range can cover the lighting range. Wherein, the sensing range can be understood as a range in a three-dimensional space where the radar module 2 can sense the human body, the sensing range is approximately conical, and the sensing included angle can be understood as an included angle of the cone in the vertical direction. The lighting range can be understood as a three-dimensional space range formed by the light emitted from the second light emitting hole 361. The embodiment of the present application covers the sensing range with the lighting range, so that the light emitting assembly 3 is lit in advance before the user enters the lighting range, thereby improving the use experience. Specifically, when the user enters the sensing range but does not enter the lighting range, the radar module 2 has sensed the user, thereby controlling the light emitting assembly 3 to be lit. In a specific embodiment, the sensing included angle is 130°, and the beam angle is 50°.
[0095] From Figure 4As can be seen, the thickness that radar waves need to pass through when they pass vertically through the hidden plate 41 is less than the thickness that they need to pass through when they pass through the hidden plate 41 at an angle. When the center of the hidden plate 41 is concave, the thickness that radar waves need to pass through when they pass through the hidden plate 41 to the right increases significantly, which reduces the sensing range on the right side of the human body induction spotlight 100. Correspondingly, the thickness that radar waves need to pass through when they pass through the hidden plate 41 to the left decreases, and the sensing range on the left increases. As a result, the overall sensing range shifts to the left, resulting in a situation where the sensing range does not correspond to the lighting range, which affects the user experience.
[0096] In one embodiment, to solve the above-mentioned technical problems, the hidden plate 41 is constructed as a flat plate.
[0097] In other embodiments, to solve the above-mentioned technical problems, the hidden plate 41 is constructed as a concave cone-shaped panel with a concave depth less than 10% of its diameter, creating a slightly concave effect. Alternatively, the hidden plate 41 is constructed as a convex cone-shaped panel with a convex height less than 10% of its diameter, creating a slightly convex effect.
[0098] This embodiment of the utility model controls the concavity / protrusion of the hidden plate 41 so that the thickness of the plate through which the radar wave passes is relatively thin. The thickness of the radar wave passing through the hidden plate 41 varies little at different positions, ensuring that the sensing range of the radar module 2 meets the requirements, and that the sensing range of the radar module 2 corresponds to the illumination range when it is installed horizontally.
[0099] For example, such as Figure 4 As shown, the hidden plate 41 is constructed as a cone-shaped panel with a slightly concave center. For example... Figure 4 As shown, the hidden plate 41 is constructed as a cone-shaped plate with a slightly concave center, the depth of which is 5% of the diameter.
[0100] In some embodiments, such as Figure 4 and Figure 5 As shown, the radar module 2 is mounted on the hidden plate 41. From Figure 4 As can be seen, the farther the radar module 2 is from the hidden plate 41, the more its sensing range is obstructed, resulting in a smaller sensing range; conversely, the closer it is to the hidden plate 41, the less its sensing range is obstructed, resulting in a larger sensing range. In this embodiment, the radar module 2 is directly mounted on the hidden plate 41, which helps to shorten the distance between the radar module 2 and the hidden plate 41, thus ensuring a sufficiently large sensing range. Furthermore, directly mounting the radar module 2 on the hidden plate 41 helps to ensure the installation accuracy and levelness of the radar module 2.
[0101] In some embodiments, such as Figure 5As shown, the radar module 2 comprises a radar circuit board 21, the radar circuit board 21 is provided with at least two mounting holes 211, the back surface of the hidden plate 41 extends mounting posts 42 at the corresponding positions of 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; the root of the mounting post 42 is provided with a positioning step 43, and the radar circuit board 21 abuts against the positioning step 43, so that the radar circuit board 21 is positioned in the vertical direction; wherein the hidden plate 41 realizes the accurate positioning of the radar circuit board 21 through the mounting post 42 and the positioning step 43, ensures the installation accuracy of the radar module 2, and the installation method is relatively convenient, which is beneficial to improve the assembly efficiency.
[0102] In an embodiment, the radar circuit board 21 is provided with three mounting holes 211, and the three mounting holes 211 are respectively located at the three right angles of the radar circuit board 21. The hidden plate 41 is provided with three mounting posts 42, and the three mounting posts 42 are respectively inserted into the mounting holes 211, so as to improve the positioning accuracy of the radar circuit board 21 in the horizontal direction. The hidden plate 41 is provided with the positioning step 43 at the four right angles of the radar circuit board 21, and the radar circuit board 21 abuts against each positioning step 43, so as to improve the positioning accuracy of the radar circuit board 21 in the vertical direction. Each positioning step 43 comprises four positioning ribs 126, and the four positioning ribs 126 are arranged around the mounting post 42. The positioning rib 126 can not only realize the vertical positioning of the radar circuit board 21, but also can strengthen the strength of the mounting post 42 and ensure the verticality of the mounting post 42.
[0103] Further, the mounting post 42 is fixedly connected with the radar circuit board 21, and the fixed connection can be hot melting, glue dispensing, clamping and the like. In an embodiment, as shown in Figure 8 When the radar circuit board 21 abuts against the positioning step 43, glue is dispensed at the connection part of each mounting post 42 and the mounting hole 211, so as to realize the fixed connection of the mounting post 42 and the radar circuit board 21. In another embodiment, as shown in Figure 10 When the radar circuit board 21 abuts against the positioning step 43, the end of each mounting post 42 is hot-melted and flattened, and the flattened mounting post 42 and the positioning step 43 clamp and fix the radar circuit board 21.
[0104] Further, as shown in Figure 3 and Figure 6As shown, the radar module 2 comprises a radar circuit board 21, and a transmitting antenna 22 and a receiving antenna 23 arranged on a first surface of the radar circuit board 21, the first surface being arranged as a surface of the radar circuit board 21 facing the radar hiding part 4. The transmitting antenna 22 comprises a first copper sheet, and the receiving antenna 23 comprises a second copper sheet, both of which are arranged on the first surface. The transmitting antenna 22 transmits radar waves at certain time intervals, and the radar waves are reflected back by a human body or an object in the environment. The receiving antenna 23 receives the reflected radar waves. A radar driving chip 24 is arranged on a surface of the radar circuit board 21 opposite to the radar hiding part 4. The power module 5 comprises 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 in the sensing range based on the Doppler principle. The main control unit controls the light emitting assembly 3 to be turned on or off based on the determination result.
[0105] Since the light emitting assembly 3 generates a large amount of heat, in order to avoid the temperature of the light emitting assembly 3 being too high, the heat dissipation performance of the lamp shell 1 needs to be improved. In this embodiment, the lamp shell 1 is made of metal, and the heat generated by the light emitting assembly 3 is dissipated through the lamp shell 1. However, the metal material will shield the radar waves, and the radar module 2 will not be able to detect the human body or the moving object in the sensing range. Figure 4 As can be seen, the closer the radar module 2 is to the side wall of the lamp shell 1, the more the radar waves on the right are blocked by the side wall of the lamp shell 1, resulting in a reduction in the sensing range on the right. The farther the radar module 2 is from the side wall of the lamp shell 1, the less the radar waves on the right are blocked by the side wall of the lamp shell 1, resulting in an expansion of the sensing range on the right. The lower the height of the radar module 2, the more the radar waves on the right are blocked by the side wall of the lamp shell 1, resulting in a reduction in the sensing range on the right. The higher the height of the radar module 2, the less the radar waves on the right are blocked by the side wall of the lamp shell 1, resulting in an expansion of the sensing range on the right. Based on this, in this embodiment, as shown in Figure 3 and Figure 4 shown, in the horizontal direction, the distance (L1 in Figure 3 ) between the receiving antenna 23 and the side wall of the lamp shell 1 is greater than 4 mm; in the vertical direction, the distance (H1 in Figure 4 ) between the receiving antenna 23 and the first end surface of the lamp shell 1 is less than 9 mm, and the first end surface is arranged at one end of the lamp shell 1 facing the light emitting direction. By designing the distance L1 between the receiving antenna and the side wall of the lamp shell, and the distance H1 between the receiving antenna and the first end surface, the sensing range is not blocked too much by the lamp shell 1, and the sensing range can cover the illumination range. The first end surface is the upper end surface of the lamp shell 1 in Figure 4 . The distance L1 between the receiving antenna 23 and the side wall of the lamp shell 1 can be understood as the vertical distance between the receiving antenna 23 and the side wall of the lamp shell 1 in the horizontal direction.
[0106] 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.
[0107] Applicants have found that the performance of radar waves is greatly related to the thickness of the hidden plate 41, and the distance between the transmitting antenna 22 and the hidden plate 41 also affects the performance of radar waves. Therefore, in some embodiments, the distance between the first surface of the radar circuit board 21 and the hidden plate 41 in the vertical direction 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, so as to reduce the influence of the inner wall of the hidden plate 41 on the radar detection wave. In an embodiment, as shown in Figure 8 the hidden plate 41 is a concave circular plate, the minimum distance between the first surface and the hidden plate 41 in the vertical direction is 1.5 mm, and the maximum distance is 2.9 mm. The hidden plate 41 is made of plastic material, and the thickness of the hidden plate 41 is greater than 0.6 mm and less than 2.5 mm, so as to ensure the penetration efficiency of the radar wave and reduce the loss of the radar wave. It is worth mentioning that if the hidden plate 41 is too thin, the radar module 2 will cast a shadow on the hidden plate 41. In this embodiment, the thickness of the hidden plate 41 is controlled to be greater than 0.6 mm, so as to avoid the radar module 2 casting a shadow on the hidden plate 41. In an embodiment, the thickness of the hidden plate 41 is 1.3 mm.
[0108] In an embodiment, the radar module 2 adopts a radar module 2 with model EDQ15P-Y-01 developed by Yisuantan Technology Co., Ltd., which has one transmitting antenna 22 and one receiving antenna 23. The radar module 2 adopts a 24 GHz wave band. When detecting human body 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 be offset due to the direction of human body movement (the frequency increases when approaching, and the frequency decreases when moving away). By analyzing the frequency difference (Doppler shift) between the reflected signal and the original signal, the speed, direction and / or distance of the human body can be calculated to realize human body detection.
[0109] In some embodiments, as shown in Figures 6-9 the radar circuit board 21 is provided with a brightness detection piece 25 facing the hidden plate 41, and the hidden plate 41 is provided with a light guide portion 44 opposite the brightness detection piece 25. The light guide portion 44 guides the light outside the human body sensing spotlight 100 into the brightness detection piece 25, so that the brightness detection piece 25 can detect the ambient brightness. The ambient brightness as the first detection result can be used in combination with the second detection result of the radar module 2 for representing whether there is a human in the environment. The following introduces two possible combined use modes.
[0110] In the first mode, the power module 5 is provided with a master control unit (for example, an embedded SOC) that receives the first detection result and the second detection result and controls the on / off of the spotlight based on a preset brightness threshold (for example, 200 lux). Specifically, the master control unit is electrically connected to the radar module 2 and the brightness detection member 25 to obtain the first detection result and the second detection result.
[0111] 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 a person in the environment, the spotlight is controlled to be turned on (i.e., the light-emitting assembly 3 is turned on). When the first detection result indicates that the ambient brightness is higher than the brightness threshold, the spotlight is controlled to be turned off (i.e., the light-emitting assembly 3 is turned off) regardless of whether the second detection result indicates that there is a person in the environment or not.
[0112] In the first mode, all control logics are executed locally on the spotlight, which is not affected by the network environment and can ensure the execution speed.
[0113] Further, the brightness threshold can be customized by a user, who can modify the brightness threshold through a terminal device that is previously associated with the spotlight.
[0114] In the second mode, the spotlight receives a network configuration operation to connect to a target network and reports the first detection result and the second detection result through the target network, so that a gateway, a cloud, and / or a terminal device in the target network can determine a control result of the spotlight according to a predefined logic rule. There can be one or more logic rules, which are predefined by a user (for example, defined through a terminal device and stored in the cloud). Each logic rule defines a trigger relationship between a logic trigger condition and a control result, and when the logic trigger condition is met, the control result will be controlled to be executed. Specifically, the cloud can receive the detection results reported by the spotlight and determine whether the logic trigger condition is met, and if so, the control result defined by the logic rule is executed, otherwise, it is not executed.
[0115] Here, the logic trigger condition in the logic rule is associated with at least one of the first detection result and the second detection result (for example, there is a person in the environment, there is no person in the environment, the brightness is in a predetermined range, etc.), and the control result at least includes one executable function of the spotlight (for example, turning on, turning off, adjusting the brightness to a specified value, adjusting the color temperature to a specified value, etc.).
[0116] In the second mode, the target network is introduced to realize more rich control logics between the first detection result, the second detection result, and the executable function of the spotlight.
[0117] In addition, the network configuration operation of the spotlight involved in the above embodiments includes:
[0118] The network configuration operation is used to trigger the spotlight to enter a network configuration mode, in which the spotlight sends out network configuration messages outside, at least carrying information representing the spotlight (such as a MAC address for uniquely representing the spotlight, factory ID information, etc.), so that a terminal device, a gateway, or other external intelligent devices scan the spotlight in the network configuration mode based on the network configuration messages, and then guide the spotlight to join a target network based on a preset network configuration mode, to complete the network configuration of the spotlight.
[0119] After the network configuration is completed, the spotlight can be connected to the target network, and then communicate with the gateway, the terminal device, and / or the cloud through the target network.
[0120] Further, after the network configuration is completed, the spotlight can directly connect with the terminal device to directly receive the control of the terminal device. After the network configuration is completed, the spotlight can also receive the control instruction from the network (such as the control instruction remotely applied by the terminal device through the cloud), and execute the corresponding function.
[0121] Further, after the network configuration is completed, the spotlight can also report the working state (on / off light state, brightness, color temperature, etc.) and / or the detection result (first detection result and / or second detection result) to the cloud, and the terminal device can obtain these working state and / or detection result from the cloud and display them to the user.
[0122] For example, when the difference between the current detected first detection result representing the ambient brightness and the last one meets the reporting condition (such as the difference between the adjacent two times of brightness is greater than 10 lux), the current detected first detection result is reported. The detection results reported by the spotlight multiple times are stored as historical records in the cloud. The user can view the change rule of the ambient brightness from the cloud or the historical records through the terminal device, and also set the required brightness threshold value accordingly.
[0123] In some embodiments, after the network configuration is completed, the user can send a shutdown instruction through the terminal device, which is used to instruct the spotlight to shut down the sensing function of the radar module 2. In this case, the spotlight will not report the second detection result, and the logic rule related to the second detection result will not be triggered.
[0124] Further, after receiving the shutdown instruction, the spotlight can keep detecting the environment by the radar module 2, but not report the second detection result to the target network. When the user directly connects with the spotlight through the terminal device, the second detection result of the radar module 2 can also be viewed.
[0125] Further, after receiving the shutdown instruction, the spotlight can also directly stop detecting 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.
[0126] Further, the radar module 2 stops detecting the environment, for example, the power supply of the radar module 2 can be controlled to be powered off. Alternatively, the power supply of the radar module 2 can be maintained, but the radar wave emission of the radar module 2 is turned off, so that the radar module 2 can quickly restore the detection capability when needed.
[0127] In some embodiments, the detection sensitivity of the radar module 2 can be changed. For example, the user can switch the detection sensitivity to high, medium, and low through the terminal device. The higher the detection sensitivity, the easier it is to trigger a person (i.e., the second detection result represents that there is a person in the environment), that is, a smaller body movement can trigger a person. Conversely, the lower the detection sensitivity, the larger the body movement required to trigger a person.
[0128] Further, the detection area of the radar module 2 is divided into a plurality of continuous spatial layers, each spatial layer has a detection sub-sensitivity for determining the difficulty of triggering a person in the spatial layer. The detection sub-sensitivity of each spatial layer is independent of each other, that is, the user can independently set the detection sub-sensitivity of any spatial layer, so that the detection sub-sensitivity of each spatial layer can be changed according to the user's needs. The range of the detection sub-sensitivity can be 0-100, the larger the value, the higher the sensitivity, the easier it is to trigger a person, and vice versa. When the detection sub-sensitivity is set to 0, the corresponding spatial layer will not be triggered by a person. Correspondingly, when the detection sub-sensitivity is set to 100, the corresponding spatial layer will always be in a state of triggering a person.
[0129] In a possible application scenario, for example, the detection area of the radar module 2 can cover a range of 6 meters (based on the lamp as the distance 0 point), and the 6-meter range is divided into 8 spatial layers with a height of 0.75 meters. The lamp is installed on the ceiling and covers a detection range of about 3 meters in the vertical direction, which includes four spatial layers (0-0.75m, 0.75-1.5m, 1.5-2.25m, 2.25-3m). The user can set the detection sub-sensitivity of the spatial layer of 2.25-3m to 0 to shield the body detection function of this spatial layer. In this way, when the pet such as a cat or a dog walks on the ground, it will not trigger a person, thereby preventing false triggering of the pet.
[0130] Further, the user can also change the triggering condition of the second detection result according to the needs. Specifically, the lamp (which can be, for example, the main control unit of the lamp) receives a switching instruction generated by the user selecting one of different trigger modes of the lamp on the terminal device. Each trigger mode has a trigger parameter, and the trigger parameters of different trigger modes are different. The value range of the trigger parameter is 1-3.
[0131] The spotlight detects whether there is a person in the environment through the radar module 2, obtains the detection result of whether there is a person in each space layer, and determines whether there are more than a set number of adjacent space layers triggered by a person; if yes, it is determined that there is a person; otherwise, it is determined that there is no person. The set number is determined according to the trigger parameter, so as to realize the setting of the trigger condition of the radar module 2 based on the switching instruction.
[0132] In some embodiments, the brightness detection piece 25 can be a photoresistor or other electronic element capable of detecting brightness. In an embodiment, the brightness detection piece 25 is a photoresistor. Further, the light guide part 44 is opposite the light-sensitive part of the photoresistor, so that the brightness detection is more accurate. The light guide part 44 can be a light guide hole, a light guide wall, a light guide column or other structure capable of guiding light.
[0133] Further, as shown in Figure 8 and Figure 5 , the light guide part 44 includes a light guide hole 441 and an annular reflective wall 442 extending from around the light guide hole 441 towards the radar circuit board 21. The annular reflective wall 442 surrounds the brightness detection piece 25, and the inside of the annular reflective wall 442 forms a reflective cavity 443. A part of the ambient light introduced by the light guide hole 441 is reflected and mixed in the reflective cavity 443 and then irradiates the brightness detection piece 25, thereby improving the accuracy of brightness detection. Further, the annular reflective wall 442 is white to improve the reflective performance of the reflective cavity 443.
[0134] In another embodiment, as shown in Figure 9 , a light guide column 444 is embedded in the light guide hole 441. The light guide column 444 closes the light guide hole 441, and the light guide column 444 is arranged directly above the brightness detection piece 25. The ambient light is conducted to the brightness detection piece 25 through the light guide column 444. The light guide column 444 is made of polymethyl methacrylate (PMMA) or polycarbonate (PC) by injection molding to improve the light guide performance.
[0135] In the prior art, the brightness detection piece 25 generally only plays a role when the lamp is not lit, that is, when the ambient brightness is too bright, the lamp is controlled not to be lit. After the lamp is lit, the light propagates inside the lamp to the brightness detection piece 25, and the data detected by the brightness detection piece 25 no longer has reference value, and the user cannot intuitively obtain the brightness change of the ambient light after the lamp is lit. To solve this problem, in the present embodiment, as shown in Figure 8As shown, the annular light-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 assembly 3 on the brightness detection member 25, and block the light emitted by the light-emitting assembly 3 from propagating to the brightness detection member 25, so that the brightness detection member 25 can relatively accurately detect the ambient light in the light-on state, thereby feeding back to the user the ambient brightness value which has more reference value, so that the user can clearly and intuitively obtain the ambient brightness change in the light-on and light-off states.
[0136] In some embodiments, as Figure 2 As shown, the first cavity 13 is formed between the radar hiding member 4 and the lamp shell 1, and the light-emitting assembly 3 is arranged inside the first cavity 13; the light-emitting assembly 3 has a light-transmitting cavity 31 for propagating light, and the light-transmitting end of the light-transmitting cavity 31 is opposite to 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-transmitting cavity 31. Wherein, the light-transmitting end opposite to the first light-emitting hole 413 can be understood as that the light-transmitting end is located directly below the first light-emitting hole 413 or the light-transmitting end is embedded in the inner side of the first light-emitting hole 413, so that the light emitted by the light-transmitting end is directly emitted out of the first light-emitting hole 413. Most of the light generated by the light-emitting assembly 3 propagates in the light-transmitting cavity 31, and the light emitted out of the light-transmitting cavity 31 is directly emitted out of the first light-emitting hole 413, and only a small part of the light enters the interlayer space between the first cavity 13 and the light-transmitting cavity 31. By arranging the radar module 2 in the interlayer space between the first cavity 13 and the light-transmitting cavity 31, the propagation of light in the lamp shell 1 to the brightness detection member 25 is reduced, so that the brightness detection member 25 can more accurately detect the ambient brightness in the light-on state. Furthermore, since only a small part of the light enters the interlayer space between the first cavity 13 and the light-transmitting cavity 31, the light transmission out of the hiding plate 41 is prevented due to the too bright light in the interlayer space, thereby avoiding the shadow of the radar module 2 on the hiding plate 41.
[0137] Further, as Figure 2 As shown, the light-emitting assembly 3 further includes a light-emitting member 32 and a condenser lens 34, and the light-transmitting end of the light-transmitting cavity 31 is provided with a second light-emitting hole 361 opposite to the first light-emitting hole 413; the light-emitting member 32 is arranged at the light-entering end of the light-transmitting cavity 31, and the condenser lens 34 is arranged inside the light-transmitting cavity 31 and located between the light-emitting member 32 and the second light-emitting hole 361, and the light emitted by the light-emitting member 32 is converged by the condenser lens 34 and then emitted out of the second light-emitting hole 361 and the first light-emitting hole 413. Wherein, the light-emitting member 32 can be understood as a module or an electronic element having a light-emitting function. In an embodiment, the light-emitting member 32 includes an LED lamp bead 322 and a light-emitting circuit board 321 carrying the LED lamp bead 322. Figure 14A schematic diagram of the light path of the light emitting element 32 emitting light at the center position. The light path shown in the diagram is only for illustration and is not used as a reference for the actual light path. The light rays converge towards the second light exit hole 361 through the condenser lens 34. The convergence point can be dispersed below, above or at the same height as the second light exit hole 361. As long as the light rays are converged near the second light exit hole 361, most of the light can be emitted from the second light exit hole 361 to reduce the loss of brightness. The light that is not converged to the second light exit hole 361 can be understood as stray light. Most of the stray light is blocked inside the light transmission cavity 31, thereby reducing the glare effect caused by the stray light.
[0138] In some embodiments, as shown in Figures 14-16 The condenser lens 34 is configured as a rotary body, and the bottom of the condenser lens 34 is provided with a light entrance recess. The opening of the light entrance recess is directly opposite the LED lamp bead 322. Most of the light emitted by the LED lamp bead 322 enters the light entrance recess and is refracted into the interior of the condenser lens 34 through the light entrance recess. The side surface of the condenser lens 34 is a total reflection surface. When the light rays are irradiated from the interior of the condenser lens 34 to the side surface of the condenser lens 34, total reflection occurs. The top of the condenser lens 34 is provided with a light exit surface 342. The light that is totally reflected is refracted out of the light exit surface 342.
[0139] 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 with PC material.
[0140] Further, as shown in Figure 15 and Figure 13 The light emitting assembly 3 extends a light shielding ring 362 around the periphery of the second light exit hole 361 towards the light exit direction. The radar hiding element 4 abuts against the light emitting assembly 3. The light shielding ring 362 is embedded in the first light exit hole 413 to avoid the light rays from the gap between the first light exit hole 413 and the second light exit hole 361 irradiating into the interlayer space, reducing the propagation of the light rays inside the lamp housing 1 to the brightness detection element 25, so that the brightness detection element 25 can more accurately detect the ambient brightness when the light is on. At the same time, the embedding of the light shielding ring 362 in the first light exit hole 413 allows the light shielding ring 362 to be radially positioned, thereby improving the positional accuracy and verticality of the light emitting assembly 3 and avoiding the inclination of the light emitting assembly 3.
[0141] Further, the inner side wall of the light shielding ring 362 and the side wall of the second light exit hole 361 are integrated together to form a horn-shaped hole with the hole diameter gradually expanding towards the light exit side.
[0142] In some embodiments, as shown in Figure 12 and Figure 13As shown, the light-emitting component 3 further includes a limiting member 33, a lens housing 35, and an anti-glare shield 36 arranged sequentially along a first direction. The first direction is the direction in which the light-emitting component 32 faces the second light-emitting hole 361. The first direction has already been shown. Figure 13 The first cavity 13 has a partition plate 121 on the side away from the radar concealment component 4, as indicated by the markings. Figure 17 As shown, the limiting member 33 limits the light-emitting element 32 to the partition plate 121, so that the heat generated by the light-emitting element 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. The partition plate 121, the side wall of the lamp housing 1, and the hidden plate 41 surround and form the first cavity 13. A plastic insulating pad 8 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. Thermally conductive 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 element 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.
[0143] like Figure 17 As shown, the light-emitting circuit board 321 is constructed as a square circuit board. LED beads 322 are positioned at the center of the circuit board 321. A first solder point is located at one right angle of the circuit board 321, and a second and third solder points are located at the opposite right angle. The circuit board 321 is connected to the power module 5 via three second wires 38, which are soldered to the first, second, and third solder points, respectively. The partition plate 121 has a second wiring hole 123 for the second wires 38 to pass through.
[0144] Since the lamp housing 1 is made of metal, the insulating pad 8 is used to improve the insulation performance between the light-emitting circuit board 321 and the partition plate 121, as well as to improve the insulation performance between the first welding point, the second welding point, the third welding point and the partition plate 121, so as to prevent the lamp housing 1 from becoming electrified.
[0145] The limiting member 33 is fixedly connected to the partition plate 121 by two connecting screws 127. The insulating pad 8 has a screw through hole at the corresponding position of the connecting screw 127. The connecting screw 127 passes through the screw through hole and is connected to the partition plate 121. The light-emitting circuit board 321 and the insulating pad 8 are clamped between the limiting member 33 and the partition plate 121. The limiting member 33 has a lamp bead receiving hole 331 in the center. The LED lamp bead 322 is received in the lamp bead receiving hole 331. The sidewall of the lamp bead receiving hole 331 can block the light emitted laterally by the LED lamp bead 322, reducing the amount of light entering the interlayer space. Figure 13 and Figure 16As shown, the outer edge of the limiting member 33 extends upwardly to form an annular light blocking wall 332, and the bottom of the lens housing 35 is embedded in the inner side of 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 light from entering the interlayer space, ensuring that the brightness detection member 25 can more accurately detect the ambient brightness when the light is on. At the same time, as shown in Figure 17 The annular light blocking wall 332 also has a wire pressing function, which can clamp the second wire 38 between the annular light blocking wall 332 and the partition plate 121.
[0146] Further, as shown in Figure 16 and Figure 15 The lens housing 35 is clamped at one end of the limiting member 33 and is sleeved at the other end of the anti-dazzle cover 36. The lens housing 35 and the anti-dazzle cover 36 are both hollow shells, and the hollow parts of the two together form the light transmission cavity 31. The anti-dazzle cover 36 is provided with the second light outlet 361 at the end away from the condenser lens 34, and the light blocking ring 362 is integrally formed on the anti-dazzle cover 36. The lens housing 35 surrounds the side of the condenser lens 34 and limits the condenser lens 34. Among them, the lens housing 35 surrounds the side of the condenser lens 34, which can prevent light from being emitted from the side of the condenser lens 34 to block light from entering the interlayer space.
[0147] Further, as shown in Figure 15 and Figure 16 The upper end of the condenser lens 34 extends outwardly to form a clamping ring 341, which surrounds the side of the condenser lens 34. The upper end of the lens housing 35 is provided with clamping protrusions 351 on both sides, and the upper end of the lens housing 35 is provided with a positioning ring surface 352. The lower surface of the clamping ring 341 of the condenser lens 34 abuts against the positioning ring surface 352, and the clamping protrusions 351 are clamped on the upper surface of the clamping ring 341. The clamping ring 341 is clamped between the positioning ring surface 352 and the clamping protrusions 351 to achieve clamping and fixing of the lens housing 35 and the condenser lens 34. The side wall of the lens housing 35 abuts against the side of the condenser lens 34 to achieve radial positioning therebetween, thereby improving the positional accuracy of the condenser lens 34.
[0148] Further, as shown in Figure 15 The side of the anti-dazzle cover 36 extends downwardly to form a sleeving ring 363, which is sleeved on the upper edge of the lens housing 35 to achieve radial positioning between the sleeving ring 363 and the lens housing 35. The downward extension of the sleeving ring 363 is relatively wide, so that the sleeving ring 363 not only has a sleeving and limiting function, but also has a light blocking function, which can block light from entering the interlayer space.
[0149] Further, asFigure 16 As shown, the bottom of the lens housing 35 is provided with a support foot 353, which abuts against the limiting member 33 to achieve 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 has a locking hole 333. The two vertical hooks 354 are respectively locked into the locking hole 333 to achieve radial positioning and locking fixation between the lens housing 35 and the limiting member 33.
[0150] In some embodiments, the lens housing 35 and the anti-glare shield 36 are both made of black plastic to improve the performance of the anti-glare shield 36 in absorbing stray light, thereby enhancing the anti-glare effect. They also reduce the light transmission performance of the lens housing 35 and the anti-glare shield 36, reducing the amount of light entering the interlayer space from the light transmission cavity 31, and ensuring that the brightness detection element 25 can more accurately detect the ambient brightness when the light is on.
[0151] In some embodiments, such as Figure 15 As shown, the focusing lens 34 has a light-emitting surface 342. An anti-glare cavity 37 is disposed between the light-emitting surface 342 and the second light-emitting aperture 361. The light emitted from the light-emitting surface 342 passes through the anti-glare cavity 37 and is then emitted outward through the second light-emitting aperture 361. The anti-glare cavity 37 can be understood as the upper part of the light-transmitting cavity 31. The function of the anti-glare cavity 37 is to absorb stray light, which can be understood as light emitted from the light-emitting surface 342 that does not converge to the second light-emitting aperture 361. The stray light is reflected multiple times within the anti-glare cavity 37, and most of it is eventually absorbed by the inner wall of the anti-glare cavity 37, thereby reducing the glare effect caused by stray light. Furthermore, the elimination of most stray light makes the light emitted from the second light-emitting aperture 361 more regular, presenting a "small hill" shape when the light rays strike the wall parallel to each other.
[0152] like Figure 13 As shown, the length of the anti-glare cavity 37 in the first direction ( Figure 13 L2) is larger than the aperture of the second light-emitting aperture 361 ( Figure 13 The distance between the light-emitting surface 342 and the second light-emitting aperture 361 is 0.6 times the diameter of the second light-emitting aperture 361, so that stray light is less likely to escape from the second light-emitting aperture 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 aperture. In one embodiment, the length of the anti-glare cavity 37 in the first direction is equal to 0.93 times the diameter of the second light-emitting aperture 361.
[0153] Furthermore, such as Figure 12As shown, the lamp shell 1 has a first end face at one end in the first direction, and the aperture diameter ΦA of the second light exit hole 361 is less than 1 / 4 of the outer diameter ΦC of the first end face, wherein the embodiment of the utility model controls the aperture diameter of the second light exit hole 361 so that the stray light emitted from the second light exit hole 361 is less, thereby improving the anti-dazzling effect; and the light emitted from the second light exit hole 361 is more regular, and when the light is parallelly incident on the wall, a "small hill" shape is presented. In an embodiment, the aperture diameter ΦA of the second light exit hole 361 is equal to 0.16 times the outer diameter ΦC of the first end face.
[0154] In some embodiments, as Figure 13 As shown, the anti-dazzling cavity 37 is configured as a cylindrical cavity, and the aperture diameter ΦA of the second light exit hole 361 is less than the diameter ΦB of the anti-dazzling cavity 37, so that the second light exit hole 361 forms a constricted opening relative to the anti-dazzling cavity 37, and the stray light is less likely to be emitted from the second light exit hole 361, and the anti-dazzling effect is better. In an embodiment, the aperture diameter ΦA of the second light exit hole 361 is equal to 13.5 mm, and the diameter ΦB of the anti-dazzling cavity 37 is equal to 22 mm.
[0155] Further, as Figure 15 As shown, the light collecting lens 34 includes an incident end and an exit end, the light emitting piece 32 is arranged at the incident end, the end face of the exit end constitutes the light exit face 342, the anti-dazzling cover 36 is arranged on the exit end of the light collecting lens 34 to form the anti-dazzling cavity 37 between the anti-dazzling cover 36 and the light exit face 342; and the anti-dazzling cover 36 is provided with the second light exit hole 361 at one end away from the light collecting lens 34.
[0156] Further, as Figure 10 As shown, the lamp shell 1 has a first end face at one end in the first direction, and the aperture diameter ΦA of the second light exit hole 361 is less than 1 / 4 of the outer diameter ΦC of the first end face, wherein the embodiment of the utility model controls the aperture diameter of the second light exit hole 361 so that the stray light emitted from the second light exit hole 361 is less, thereby improving the anti-dazzling effect; and the light emitted from the second light exit hole 361 is more regular, and when the light is parallelly incident on the wall, a "small hill" shape is presented. In an embodiment, the aperture diameter ΦA of the second light exit hole 361 is equal to 0.16 times the outer diameter ΦC of the first end face.

[0158] Further, the human body sensing spotlight 100 includes the power module 5 and the power supply shell 6 arranged outside the first cavity 13. The lamp shell 1 is provided with a partition plate 121 between the power module 5 and the first cavity 13. The power supply shell 6 is connected to the partition plate 121, and a second cavity 61 is formed between the power supply shell 6 and the partition plate 121. The power module 5 is arranged inside the second cavity 61. The radar module 2 and the light emitting assembly 3 are respectively electrically connected to the power module 5.
[0159] In some embodiments, as shown in Figure 12 The radar module 2 includes a radar circuit board 21, and the power module 5 includes a power board 51.

The power board 51 controls the brightness of the LED lamp bead 322 through the second wire 38. In an embodiment, as shown in Figure 17 The LED lamp bead 322 is a double-color temperature LED lamp bead 322. The number of the second wire 38 is three. The power board 51 is provided with a light driving unit. The light driving unit is electrically connected to the second wire 38.

In addition, Figure 22The power module 5 in the power module 5 hides other electronic components except the power board 51 and the plug-in port 52. The length of the first wire 7 shown in the figure is only a schematic length and does not represent the actual length. In an embodiment, the number of the first wire 7 is four. The radar circuit board 21 is provided with four first welding holes 212 near the edge. One end of the first wire 7 is inserted into the first welding hole 212 and is welded and fixed. The other end of the first wire 7 is connected to the terminal 71. Further, the size of the first wire hole 122 is greater than the size of the terminal 71 in the horizontal direction, so that the terminal 71 can pass through the first wire hole 122 vertically downward.
[0161] In order to improve the safety of electricity use and eliminate the risk of electrification of the lamp shell 1, in an embodiment, the four first wires 7 are externally sleeved with an insulating sleeve (not shown in the figure), which wraps the four first wires 7 inside to improve the insulation performance of the first wires 7 and avoid the conduction of the first wires 7 with the lamp shell 1. Each second wire 38 is sleeved with an insulating sleeve (not shown in the figure) to improve the insulation performance of the second wire 38 and avoid the conduction of the second wire 38 with the lamp shell 1.
[0162] The structure of the power module 5 is shown in Figure 20 and Figure 21 The power module 5 includes the power board 51 and the electronic components arranged on the power board 51.

Among them, Figure 20 and Figure 21 Only a part of the electronic components is shown on the power board 51 and all the electronic components are not shown.
[0163] As shown in Figure 20 and Figure 17 One end of the power board 51 is provided with three second welding holes 511 near the edge.

The power line 62 is provided with a anti-escape rubber head 621 inside the power shell 6, and the size of the anti-escape rubber head 621 is greater than the size of the wire passing hole, so as to avoid the power line 62 from escaping outward from the power shell 6; the power shell 6 is provided with an anti-escape buckle 63 on both sides of the anti-escape rubber head 621, the anti-escape buckle 63 is clamped on both sides of the anti-escape rubber head 621, and the anti-escape rubber head 621 is fixed.
[0165] Further, as shown in Figure 21 、 Figure 18 and Figure 23 , the power panel 51 is provided with two second connecting holes 513, the power shell 6 is provided with a second connecting column 64 at the position corresponding to the second connecting hole 513, the second connecting column abuts against the lower surface of the power panel 51, and a second screw 641 is connected to the second connecting column 64 through the second connecting hole 513, so that the power panel 51 and the power shell 6 are fixedly connected. It is worth noting that the two second connecting holes 513 are respectively arranged at the positions close to the edges of the two ends of the power panel 51, so that the spacing between the two second connecting holes 513 is large, and the positioning accuracy of the power panel 51 in the horizontal direction is improved.
[0166] Further, as shown in Figures 17-19 , the partition plate 121 is provided with two first connecting holes 124, the power shell 6 is provided with a first connecting column 65 at the position corresponding to each first connecting hole 124, and a first screw 651 is connected to the first connecting column 65 through the first connecting hole 124, so as to realize the fixed connection between the partition plate 121 and the power shell 6. Further, the side of the lamp shell 1 extends an arc-shaped positioning wall 125 towards the power shell 6, the arc-shaped positioning wall 125 surrounds the side of the power shell 6, and is used for the radial positioning of the power shell 6. The side wall of the power shell 6 is provided with a positioning groove 66 at the opening end, the partition plate 121 is provided with a positioning rib 126 protruding at the position corresponding to the positioning groove 66, and the positioning rib 126 is embedded in the positioning groove 66 to realize the circumferential positioning between the power shell 6 and the first shell 11. The positioning of the power shell 6 and the lamp shell 1 is used to facilitate the accurate screwing of the first screw 651 into the first connecting column 65 during assembly, so as to improve the assembly efficiency.
[0167] In some embodiments, as shown in Figure 18As shown, the lamp shell 1 comprises a first shell 11 and a second shell 12, the first shell 11 is coaxially arranged with the second shell 12, and the two are connected through threads; the partition plate 121 is integrally formed on the second shell 12, the radar hidden part 4 is clamped on the first shell 11, the first shell 11, the second shell 12 and the radar hidden part 4 surround to form the first cavity 13; the first shell 11 and the second shell 12 are made of aluminum alloy material. Among them, the partition plate 121 is integrally formed on the second shell 12, so that the partition plate 121 is seamlessly connected with the second shell 12, which is beneficial to better conduct heat from the partition plate 121 to the second shell 12 and the first shell 11, thereby improving the heat dissipation capacity of the lamp shell 1. And thanks to the excellent heat conduction rate of the aluminum alloy material, the heat dissipation capacity of the lamp shell 1 is further improved. The threaded connection can be understood as that the first shell 11 and the second shell 12 are respectively provided with threads capable of cooperating with each other, and the two are locked through relative rotation, so that they are fixedly connected. Further, the arc-shaped positioning wall 125 is integrally formed on the second shell 12.
[0168] It is worth mentioning that the lamp shell 1 is combined by the first shell 11 and the second shell 12, which can make the assembly more convenient. Specifically, the human body sensing spotlight 100 provided by the utility model is more complex in assembly, and the assembly steps are as follows: Figure 12As shown, firstly, the power module 5 is fixed inside the power housing 6, the anti-detachment rubber head 621 is snapped into the anti-detachment buckle 63, and the power cord 62 is soldered to the power board 51. Next, the first wire 7 and the second wire 38 are passed through the partition plate 121 respectively. One end of the first wire 7 is soldered to the radar circuit board 21, and the other end is plugged into the power board 51 through the terminal block 71; one end of the second wire 38 is soldered to the power board 51, and the other end is soldered to the light-emitting element 32. Then, the power housing 6 is fixedly installed on the partition plate 121, and the power module 5 is sealed inside the second cavity 61. Next, the limiting member 33 is installed on the partition plate 121, and the limiting member 33 limits the light-emitting element 32 to the partition plate 121. The focusing lens 34 is snapped into the lens housing 35, and the lens housing 35 is snapped into the limiting member 33. The anti-glare cover 36 is fitted onto the top of the lens housing 35. Next, the first housing 11 is fitted onto the outside of the first wire 7, and the radar circuit board 21 is installed on the radar concealment part 4 through the first housing 11. Finally, the first housing 11 is rotated and connected to the second housing 12, and the radar concealed component 4 is snapped into the first housing 11, completing the assembly. During this installation process, thanks to the lamp housing 1 being composed of the first housing 11 and the second housing 12, the first housing 11 can be kept tilted while the radar circuit board 21 is installed into the radar concealed component 4. This allows for more space to be reserved so that the first wire 7 can be installed within a limited length, thus improving the assembly speed. After the radar circuit board 21 is installed into the radar concealed component 4, the first housing 11 is rotated and connected to the second housing 12.
[0169] Furthermore, such as Figure 5 and Figure 4 As shown, the radar concealment component 4 includes a concealment plate 41 and four connecting hooks 45 disposed on the back of the concealment plate 41. The four connecting hooks 45 are evenly distributed circumferentially. A snap-fit groove 111 is provided around the inner wall of the first housing 11. When the radar concealment component 4 is installed on the first housing 11, the back of the concealment plate 41 abuts against the first housing 11, and the connecting hooks 45 are snapped into the snap-fit groove 111. Furthermore, to prevent the concealment plate 41 from being disassembled by the user, when installing the concealment plate 41, glue is first applied to the connecting hooks 45, and then the connecting hooks 45 are snapped into the snap-fit groove 111.
[0170] In some embodiments, the power supply housing 6 is integrally molded from plastic, and the power board 51 is provided with a wireless communication module 53. The plastic material of the power supply housing 6 does not shield the wireless signal, thus ensuring the strength of the wireless signal. Figure 21 As shown, the wireless communication module 53 includes a communication antenna 531. The power board 51 has a notch at the corresponding position of the communication antenna 531 to prevent the power board 51 from shielding the communication antenna 531, thereby improving the wireless signal strength.
[0171] Further, since the second shell 12 is made of aluminum alloy material, the second shell 12 has shielding effect on wireless signal. In the embodiment, in order to weaken the shielding effect of the second shell 12, as shown, the arc-shaped positioning wall 125 of the second shell 12 is not annular, but has shielding-avoiding gaps 1251 on two sides, and the wireless communication module 53 is arranged at a position corresponding to one of the shielding-avoiding gaps 1251, and wireless signal is sent out from the shielding-avoiding gaps 1251 to weaken the shielding effect of the arc-shaped positioning wall 125. Moreover, the communication antenna 531 of the wireless communication module 53 is directed outward (as shown), further increasing the strength of wireless signal. Figure 19 Figure 20
