Therefore, the features limited by "first", "second" can explicitly or implicitly include one or more features.
[0052] In the description of the utility model specification, unless otherwise clear and definite and limited, the term "connection" should be broad sense understanding, for example, can be fixed connection, can also be detachable connection, or integrated;Can be mechanical connection, can also be electrical connection or can communicate with each other;It can be directly connected, can also be indirectly connected through intermediate medium, can be the communication or the interaction relationship of two elements inside two elements.For ordinary skilled in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific circumstances.
[0053] The technical scheme in the embodiments of the utility model will be described clearly and completely in the description of the embodiments of the utility model with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments.The technical scheme of each embodiment can be combined with each other, but it must be based on that the technical scheme can be realized by the person skilled in the art, when the combination of the technical scheme appears contradictory or unachievable, it should be considered that the combination of the technical scheme does not exist, also not in the protection scope required by the utility model.
[0054] 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 multiple 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 occur.Therefore, the market urgently needs a spotlight with human body sensing function.
[0055] 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, 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.
[0056] In order to solve the above problems, according to the first aspect of the utility model, a kind of anti-dazzle spotlight 100 with human body sensing function is provided, please refer to Figures 1-23 The anti-dazzle spotlight 100 provided by the utility model will be specifically explained.Specifically, as Figures 1-3As shown, the anti-dazzling spotlight 100 comprises: a radar module 2 for radiating radar waves to detect human bodies; a light-emitting assembly 3 for radiating visible light to illuminate; a lamp shell 1, the radar module 2 and the light-emitting assembly 3 are arranged inside the lamp shell 1, one side of the lamp shell 1 forms a radiation area, the radiation area comprises: a first area 411 for radiating visible light, a second area 412 for radiating radar waves. Wherein, 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 module 2 radiates radar waves to the 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 the infrared sensor, the radar module 2 has the advantage of being able to sense the subtle movements of the human body, such as breathing, heartbeat, etc., when the human body is stationary, the radar module 2 can sense the presence of the human body, thereby controlling the light-emitting assembly 3 to maintain the lighting state.
[0057] The radar module 2 and the light-emitting assembly 3 are integrated in the lamp shell 1, so that the spotlight has illumination and human body sensing functions at the same time, the user does not need to install a human body sensing device separately, and does not need to adjust the sensing direction, so that the installation convenience is greatly improved. And because the first area 411 and the second area 412 are arranged on the same side of the lamp shell 1, the visible light and the radar waves are emitted towards the same side, the illumination direction and the sensing direction tend to be in the same direction, when the user approaches the illumination area, the spotlight can more timely sense the human body, improve the response speed and sensing accuracy, and avoid problems such as untimely triggering, not triggering or false triggering of the anti-dazzling spotlight 100.
[0058] In the embodiment of the utility model, the first area 411 and the second area 412 are independent of each other, so as to integrate the radar module 2 in the lamp shell 1, so that the spotlight can have illumination and human body sensing functions. At the same time, the two areas (411 and 412) are arranged independently of each other, so that the radar module 2 will not interfere with the radiation of visible light, and the light-emitting assembly 3 will not interfere with the emission and reception of radar waves, ensuring the coordination speed of the light-emitting function and the human body sensing function. At the same time, the first area 411 and the second area 412 are independent of each other, so that the light-emitting assembly 3 and the radar module 2 are arranged side by side on the light-emitting side of the anti-dazzling spotlight 100, thereby realizing the integration of the radar module 2 and the light-emitting assembly 3 in the lamp shell 1.
[0059] Further, as shown, Figure 3 The position relationship among the lamp shell 1, the light-emitting assembly 3 and the radar module 2 is shown, wherein, Figure 3 The radar hidden part 4 is not shown in the figure. Figure 3The light-emitting assembly 3 in the lamp shell 1 is not in contact with the radar module 2, and the two are arranged side by side in the horizontal direction.
[0060] Further, as shown in Figure 1 and Figure 2 , one side of the lamp shell 1 is open, the open end cover of the lamp shell 1 is provided with a radar hiding piece 4, the radar hiding piece 4 is provided with a cover hole 413, the light emitted by the light-emitting assembly 3 is emitted outward through the cover hole 413 to form the first area 411 within the cover hole 413; the radar module 2 is hidden inside the radar hiding piece 4 (that is, the radar module 2 is hiddenly arranged inside the radar hiding piece 4), and the radar wave emitted by the radar module 2 is emitted outward through the radar hiding piece 4 to form the second area 412 on the radar hiding piece 4. Wherein, 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 the side towards the inside of the lamp shell 1. The first area 411 can be a part of the area within the cover hole 413, or the whole area within the cover hole 413, in an embodiment, as shown in Figure 1 , the first area 411 is only a part of the area within the cover hole 413. It can be understood that in some feasible embodiments, the radar module 2 can be directly installed on the radar hiding piece 4, or can be installed on other structures, as long as the radar module 2 is limited inside the radar hiding piece 4, it is within the protection scope of the utility model.
[0061] The utility model utilizes the penetrability of radar wave, hides the radar module 2 inside the radar hiding piece 4, and the radar wave is emitted outward through the radar hiding piece 4, which guarantees the working performance of the radar module 2 while avoiding the exposure of the radar module 2. The light-emitting assembly 3 radiates visible light outward through the cover hole 413, which guarantees that the intensity of the radiated visible light meets the demand. At the same time, the first area 411 is limited within the range of the cover hole 413, so that the radar hiding piece 4 has enough space to arrange the radar module 2, and the radar module 2 and the light-emitting assembly 3 can be integrated together inside the lamp shell 1.
[0062] Compared with the infrared sensor, the radar module 2 adopted by the utility model can sense the static human body, so that the sensing sensitivity is improved, in addition, it also has the following advantages: the infrared sensor needs to be opened on the radar hiding piece 4, and the Fresnel lens of the infrared sensor is exposed, which will damage the integrity of the anti-dazzle light 100, and the radar module 2 adopted in the embodiment of the utility model is perfectly hidden at the back of the radar hiding piece 4, which retains the integrity of the anti-dazzle light 100.
[0063] Further, the radar hiding piece 4 is made of non-transparent non-metal material, which can not only hide the radar module 2, but also will not shield the radar wave. In an exemplary embodiment, the radar hiding piece 4 is made of white plastic material.
[0064] Further, as shown in Figures 1-3 the radar hiding piece 4 includes a circular cover plate 41, the cover plate hole 413 is arranged in the central region of the circular cover plate 41, and the region of the circular cover plate 41 except the cover plate hole 413 is set as a radar arrangement region. The aperture of the cover plate hole 413 is less than 40% of the diameter of the circular cover plate 41, so that the radar module 2 can be arranged in the radar arrangement region, that is, by controlling the aperture of the cover plate hole 413, the radar hiding piece 4 has enough space to arrange the radar module 2, avoiding interference between the radar module 2 and the light-emitting assembly 3, and avoiding the radar module 2 being 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.
[0065] Wherein, the radar module 2 arranged in the radar arrangement region can be understood as the radar module 2 arranged in the space directly below the radar arrangement region, that is, the projection figure generated by the vertical projection of the radar module 2 does not exceed the radar arrangement region. The circular cover plate 41 can be understood as a plate structure, including a flat plate, a curved plate, etc. The central region of the cover plate 41 can be understood as a region close to the center of the cover plate 41, that is, the first light-emitting hole 413 can be located at the center of the cover 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-emitting hole 413 is arranged at the center of the cover plate 41.
[0066] In an embodiment, the aperture of the cover plate hole 413 is equal to 24% of the diameter of the circular cover plate 41, so that there is more enough space on the back of the radar hiding piece 4 to arrange the radar module 2, and the radar wave is not easy to be shielded by the lamp shell 1.
[0067] 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 the sensing range can cover the illumination range, so that when the user approaches the illumination area from different directions, the radar module 2 can timely sense and control the light-emitting assembly 3 to be lit.
[0068] In some embodiments, as shown in 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 anti-dazzle spotlight 100 is smaller than the sensing angle of the radar module 2, so that the sensing range can cover the illumination range. The sensing range can be understood as a range in a three-dimensional space where the radar module 2 can sense a human body, and the sensing range is approximately conical, and the sensing angle can be understood as an angle of the cone in the vertical direction. The illumination range can be understood as a three-dimensional space range formed by the light emitted from the light exit hole 361. The embodiment of the present application covers the illumination range with the sensing range, so that the user can light up the light emitting assembly 3 in advance before entering the illumination range, thereby improving the use experience. Specifically, when the user enters the sensing range but does not enter the illumination range, the radar module 2 has sensed the user, so as to control the light emitting assembly 3 to light up. In a specific embodiment, the sensing angle is 130°, and the beam angle is 50°.
[0069] From Figure 4 It can be seen that the thickness required to be passed by the radar wave when vertically passing through the circular cover plate 41 is smaller than the thickness required to be passed when obliquely passing through the circular cover plate 41. When the central depression amplitude of the circular cover plate 41 is large, the thickness required to be passed by the radar wave when passing through the circular cover plate 41 to the right side is greatly increased, which reduces the sensing range of the anti-dazzle spotlight 100 on the right side. Correspondingly, the thickness required to be passed by the radar wave when passing through the circular cover plate 41 to the left side is reduced, and the sensing range on the left side is increased, so that the overall sensing range is shifted to the left, and the sensing range does not correspond to the illumination range, thereby affecting the use experience.
[0070] In an embodiment, to solve the above technical problem, the circular cover plate 41 is configured as a flat plate.
[0071] In other embodiments, to solve the above technical problem, the hidden plate 41 is configured as a conical plate with a central depression, and the depression depth is less than 10% of the diameter, so as to form a slightly depressed effect. Alternatively, the hidden plate 41 is configured as a conical plate with a central protrusion, and the protrusion height is less than 10% of the diameter, so as to form a slightly protruding effect.
[0072] The embodiment of the present application controls the depression / protrusion amplitude of the circular cover plate 41, so that the thickness of the radar wave passing through the circular cover plate 41 is thin, and the thickness of the radar wave passing through the circular cover plate 41 at different positions is small, so as to ensure that the sensing range of the radar module 2 meets the requirements, and the sensing range corresponds to the illumination range when the radar module 2 is installed horizontally.
[0073] For example, as shown in Figure 4 The circular cover plate 41 is configured as a conical plate with a slightly depressed center. For example, as shown in Figure 4 The circular cover plate 41 is configured as a conical plate with a slightly depressed center, and the depression depth is 5% of the diameter.
[0074] In some embodiments, as shown in Figure 4 and Figure 5 The radar module 2 is installed on the circular cover plate 41. As can be seen from Figure 4 , the farther the radar module 2 is from the circular cover plate 41, the more the sensing range is blocked, and the smaller the sensing range is; the closer the radar module 2 is to the circular cover plate 41, the less the sensing range is blocked, and the larger the sensing range is. In the embodiment, the radar module 2 is directly installed on the circular cover plate 41, which is beneficial to shorten the distance between the radar module 2 and the circular cover plate 41, so that the sensing range is large enough; in addition, the radar module 2 is directly installed on the circular cover plate 41, which is beneficial to ensure the installation accuracy and levelness of the radar module 2.
[0075] In some embodiments, as shown in Figure 5 The radar module 2 includes a radar circuit board 21, the radar circuit board 21 is provided with at least two mounting holes 211, the back surface of the circular cover plate 41 extends a mounting column 42 at the corresponding position of each mounting hole 211, and the mounting column 42 is inserted into the mounting hole 211, so that the radar circuit board 21 is positioned in the horizontal direction; the root of the mounting column 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 circular cover plate 41 realizes accurate positioning of the radar circuit board 21 through the mounting column 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.
[0076] 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 three right angles of the radar circuit board 21. The circular cover plate 41 is provided with three mounting columns 42, and the three mounting columns 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 circular cover plate 41 is provided with the positioning steps 43 at 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 includes four positioning ribs 126, and the four positioning ribs 126 are arranged around the mounting column 42. The positioning rib 126 can not only realize the vertical positioning of the radar circuit board 21, but also strengthen the strength of the mounting column 42 and ensure the verticality of the mounting column 42.
[0077] Further, the mounting column 42 is fixedly connected with the radar circuit board 21, and the fixed connection can be hot melting, glue dispensing, clamping, etc. In an embodiment, as shown in Figure 8As shown, after the radar circuit board 21 abuts against the positioning step 43, the connecting parts of each mounting column 42 and the mounting hole 211 are glued to realize the fixed connection of the mounting column 42 and the radar circuit board 21. In another embodiment, as shown in Figure 10 As shown, after the radar circuit board 21 abuts against the positioning step 43, the ends of each mounting column 42 are hot-melted and flattened, and the flattened mounting column 42 and the positioning step 43 clamp and fix the radar circuit board 21.
[0078] Further, as shown in Figure 3 and Figure 6 The radar module 2 includes the radar circuit board 21 and the transmitting antenna 22 and the receiving antenna 23 arranged on the first surface of the radar circuit board 21, and the first surface is arranged as the side of the radar circuit board 21 facing the radar hiding part 4. The transmitting antenna 22 includes a first copper sheet, and the receiving antenna 23 includes a second copper sheet, and the first copper sheet and the second copper sheet are arranged on the first surface. The transmitting antenna 22 transmits radar waves at a certain time interval, and the radar waves are reflected back by the human body or the object in the environment. The receiving antenna 23 receives the reflected radar waves, and the side of the radar circuit board 21 away from the radar hiding part 4 is provided with a radar driving chip 24. The power module 5 includes a master control unit, and the radar driving chip 24 or the master control unit judges whether there is a human body or a moving object in the sensing range based on the Doppler principle. The master control unit controls the light-emitting assembly 3 to be turned on or turned off based on the judgment result.
[0079] Since the light-emitting assembly 3 has a large heat generation, 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 material, 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. Through Figure 4 It can be seen that 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 the sensing range on the right being reduced. 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 the sensing range on the right being expanded. 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 the sensing range on the right being reduced. 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 the sensing range on the right being expanded. Based on this, in this embodiment, as shown in Figure 3 and Figure 4 In the horizontal direction, the distance between the receiving antenna 23 and the side wall of the lamp shell 1 (L1 in Figure 3 ) is greater than 4 mm; in the vertical direction, the distance between the receiving antenna 23 and the first end surface of the lamp shell 1 (L2 in Figure 4H1) is less than 9 mm, the first end face being arranged at one end of the lamp housing 1 facing the light emission 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 sensing range is not blocked too much by the lamp housing 1 and can cover the illumination range. The first end face is the upper end face of the lamp housing 1 in the embodiment. Figure 4 The distance L1 between the receiving antenna 23 and the side wall of the lamp housing 1 can be understood as the vertical distance between the receiving antenna 23 and the side wall of the lamp housing 1 in the horizontal direction.
[0080] 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.
[0081] Applicants have found that the performance of the radar wave is greatly related to the thickness of the circular cover plate 41, and the distance between the transmitting antenna 22 and the circular cover plate 41 also affects the performance of the radar wave. Therefore, in some embodiments, the distance between the first surface of the radar circuit board 21 and the circular cover 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 circular cover plate 41 on the radar detection wave. In an embodiment, as shown in Figure 8 the circular cover plate 41 is a concave circular plate, the minimum distance between the first surface and the circular cover plate 41 in the vertical direction is 1.5 mm, and the maximum distance is 2.9 mm. The circular cover plate 41 is made of plastic material, and the thickness of the circular cover 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 thickness of 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 to avoid the radar module 2 casting a shadow on the hidden plate 41. In an embodiment, the thickness of the circular cover plate 41 is 1.3 mm.
[0082] In an embodiment, the radar module 2 adopts a radar module 2 with one transmitting antenna 22 and one receiving antenna 23 developed by EasyQuest Technology Co., Ltd. with model number EDQ15P-Y-01. 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 the 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 achieve human body detection.
[0083] In some embodiments, such as Figures 6-9 As shown, a brightness detection element 25 is disposed on the radar circuit board 21 facing the circular cover plate 41. A light guide portion 44 is disposed on the circular cover plate 41 directly opposite the brightness detection element 25. The light guide portion 44 guides light from outside the anti-glare spotlight 100 into the brightness detection element 25, enabling the brightness detection element 25 to detect ambient brightness. This ambient brightness, as a first detection result, can be used in conjunction with a second detection result from the radar module 2 to characterize whether the environment is occupied or unoccupied. Two possible methods of combined use are described below.
[0084] Method 1: The main control unit (e.g., an embedded SOC) in the power module 5 receives the first detection result and the second detection result, and controls the spotlight to turn on / off based on a preset brightness threshold (e.g., 200 lux). Specifically, the main control unit is electrically connected to the radar module 2 and the brightness detection element 25 respectively to obtain the first detection result and the second detection result.
[0085] Specifically, when the first detection result indicates that the ambient brightness is lower than the brightness threshold, and the second detection result indicates that there are people in the environment, the spotlight is turned on (i.e., the light-emitting component 3 is turned on). When the first detection result indicates that the ambient brightness is higher than the brightness threshold, the spotlight is turned off (i.e., the light-emitting component 3 is turned off) regardless of whether the second detection result indicates that there are people in the environment or not.
[0086] In Method 1, all control logic is executed locally on the spotlight, unaffected by the network environment, and local execution ensures execution speed.
[0087] Furthermore, the brightness threshold can be customized by the user, who can modify the brightness threshold through a terminal device that has been pre-associated with the spotlight.
[0088] Method 2: The spotlight receives network configuration operations to connect to the target network and reports both the first and second detection results through the target network. This allows the gateway, cloud, and / or terminal devices in the target network to determine the control result of the spotlight according to predefined logical rules. There can be one or more logical rules. These logical rules are predefined by the user (e.g., defined by the terminal device and stored in the cloud). Each logical rule defines the triggering relationship between logical triggering conditions and control results. When the logical triggering condition is met, the control result will be executed. Specifically, for example, the cloud receives the detection results reported by the spotlight and determines whether the logical triggering condition has been met. If it has, the control result defined by the logical rule is executed; otherwise, it is not executed.
[0089] Here, the logical trigger condition in the logical rule is associated with at least one of the first detection result, the second detection result (for example, whether there is a person in the environment, whether there is no person in the environment, whether 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.).
[0090] In the second mode, a target network is introduced to implement more rich control logic between the first detection result, the second detection result and the executable function of the spotlight.
[0091] In addition, the network configuration operation of the spotlight involved in the above embodiments includes:
[0092] The network configuration operation is used to trigger the spotlight to enter a network configuration mode, and in the network configuration mode, the spotlight sends out network configuration messages outside, and at least carries information representing the spotlight (for example, a MAC address used to uniquely represent the spotlight, factory ID information, etc.) in the network configuration messages, so that the terminal device, the gateway and other external intelligent devices based on the network configuration message scan the spotlight in the network configuration mode, and then based on the preset network configuration mode, guide the spotlight to join the target network, to complete the network configuration of the spotlight.
[0093] 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.
[0094] 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 (for example, the control instruction remotely applied by the terminal device through the cloud), and execute the corresponding function.
[0095] 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 (the first detection result and / or the second detection result) to the cloud, and the terminal device can obtain these working states and / or detection results from the cloud and display them to the user.
[0096] For example, when the difference between the current detected first detection result and the last one meets the reporting condition (for example, the difference between the adjacent two brightness values 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 brightness from the cloud or the historical records through the terminal device, and can also set the required brightness threshold value according to the change rule.
[0097] In some embodiments, after the network configuration is completed, the user can send a closing instruction through the terminal device, which is used to instruct the spotlight to close the sensing function of the radar module 2. In this case, the spotlight does not report the second detection result, and the logic rule related to the second detection result is not triggered.
[0098] Further, after receiving the closing instruction, the spotlight can maintain the detection of the radar module 2 on the environment, and only not report the second detection result to the target network. When the user directly connects with the spotlight through the terminal device, the user can also view the second detection result of the radar module 2.
[0099] Further, after receiving the closing instruction, the spotlight can also directly stop the detection of the radar module 2 on the environment based on the closing instruction. At this time, the radar module 2 stops working, which can save power consumption.
[0100] Further, stopping the detection of the radar module 2 on the environment can control the power supply of the radar module 2 to be powered off, for example. The power supply of the radar module 2 can also be reserved, but the radar wave emission thereof is closed, so that the radar module 2 can quickly restore the detection capability when needed.
[0101] In some embodiments, the detection sensitivity of the radar module 2 can be changed. For example, the user switches 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 human body action can trigger a person. Conversely, the lower the detection sensitivity, the larger human body action is needed to trigger a person.
[0102] 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, which is used to determine 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 changes 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, and correspondingly, when the detection sub-sensitivity is set to 100, the corresponding spatial layer will always be in a state of triggering a person.
[0103] In one possible application scenario, the detection area of the radar module 2 can cover a range of 6 meters (based on the spotlight as the distance 0 point), and the 6-meter range is divided into 8 spatial layers with a height of 0.75 meters as a spatial layer. After the spotlight is installed on the ceiling, it will cover a detection range of about 3 meters in the vertical direction, which includes four spatial layers (0-0.75 m, 0.75-1.5 m, 1.5-2.25 m, and 2.25-3 m). The user can set the detection sub-sensitivity of the spatial layer of 2.25-3 m to 0 to shield the human body detection function of this spatial layer. In this way, when a pet such as a cat or a dog walks on the ground, the pet will not trigger a person, thereby preventing false triggering of the pet.
[0104] Further, the user can also change the triggering condition of the second detection result according to the needs. Specifically, the spotlight (specifically, for example, the master control unit of the spotlight) receives a switching instruction generated by the user selecting one of different trigger modes of the spotlight on a 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.
[0105] 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 spatial layer, and determines whether there are a set number of adjacent spatial 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 set the triggering condition of the radar module 2 based on the switching instruction.
[0106] In some embodiments, the brightness detection piece 25 can be a photoresistor or other electronic element capable of detecting brightness. In one embodiment, the brightness detection piece 25 is a photoresistor. Further, the light guide portion 44 is perpendicular to the light-sensitive part of the photoresistor to make the brightness detection more accurate. The light guide portion 44 can be a light guide hole, a light guide wall, a light guide column, or other structures capable of guiding light.
[0107] Further, as shown in Figure 8 and Figure 5 The light guide portion 44 includes a light guide hole 441 and an annular reflective wall 442 extending from the periphery of 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.
[0108] In another embodiment, as shown in Figure 9As shown, the light guide hole 441 is embedded with a light guide column 444, which closes the light guide hole 441. The light guide column 444 is arranged right above the brightness detection member 25, and the ambient light is conducted to the brightness detection member 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.
[0109] In the prior art, the brightness detection member 25 generally only functions when the lamp is not lit, and functions to control the lamp to not be lit when the ambient brightness is too bright. 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 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 8 As shown, the annular light reflection 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 in the light-on state, the brightness detection member 25 can relatively accurately detect the ambient light, 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.
[0110] In some embodiments, as shown in 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 transmission cavity 31 for propagating light, and the light emitting end of the light transmission cavity 31 is right opposite to the cover 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. Wherein, the light emitting end being right opposite to the cover hole 413 can be understood as that the light emitting end is located right below the cover hole 413 or is embedded in the inner side of the cover hole 413, so that the light emitted by the light emitting end is directly emitted out of the cover hole 413. Most of the light generated by the light emitting assembly 3 propagates in the light transmission cavity 31, and the light emitted out of the light transmission cavity 31 is directly emitted out of the cover hole 413. Only a small part of the light enters the interlayer space between the first cavity 13 and the light transmission cavity 31. By arranging the radar module 2 in the interlayer space between the first cavity 13 and the light transmission cavity 31, the light propagating inside 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 transmission cavity 31, the light is prevented from being emitted out of the circular cover plate 41 due to the light being too bright in the interlayer space, thereby avoiding the radar module 2 from casting a shadow on the circular cover plate 41.
[0111] Further, as shown in Figure 2As shown, the light emitting assembly 3 further comprises a light emitting element 32 and a condenser lens 34, and the light emitting end of the light transmitting cavity 31 is provided with a light emitting hole 361 opposite to the cover hole 413; the light emitting element 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 between the light emitting element 32 and the light emitting hole 361, and the condenser lens 34 converges the light emitted by the light emitting element 32 and then emits the light outwards through the light emitting hole 361 and the cover hole 413. The light emitting element 32 can be understood as a module or an electronic element having a light emitting function, and in an embodiment, the light emitting element 32 comprises an LED lamp bead 322 and a light emitting circuit board 321 carrying the LED lamp bead 322. Figure 14 The light path diagram of the light emitted by the light emitting element 32 at the center position is shown in the figure, wherein 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 is converged towards the light emitting hole 361 by the condenser lens 34, and the convergence point can be dispersed below, above or at the same height as the light emitting hole 361, as long as the light is converged near the light emitting hole 361, so that most of the light can be emitted from the light emitting hole 361 to reduce the loss of brightness. The light not converged to the light emitting hole 361 can be understood as stray light, and most of the stray light is blocked inside the light transmitting cavity 31, thereby reducing the glare effect caused by the stray light.
[0112] 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 entering recessed cavity, and the opening of the light entering recessed cavity is opposite to the LED lamp bead 322. Most of the light emitted by the LED lamp bead 322 enters the light entering recessed cavity and is refracted into the interior of the condenser lens 34 through the light entering recessed cavity. The side surface of the condenser lens 34 is a total reflection surface, and the light is totally reflected when the light is irradiated from the interior of the condenser lens 34 to the side surface of the condenser lens 34. The top of the condenser lens 34 is provided with a light emitting surface 342, and the totally reflected light is refracted out from the light emitting surface 342.
[0113] The material of the condenser lens 34 can be PMMA, PC or resin, and in a preferred embodiment, the condenser lens 34 is integrally injection molded by using PC material.
[0114] Further, as shown in Figure 15 and Figure 13As shown, the light emitting assembly 3 extends out a shading ring 362 towards the light emitting direction at the periphery of the light emitting hole 361, the radar hidden part 4 abuts against the light emitting assembly 3, and the shading ring 362 is embedded in the cover hole 413, so that the shading effect is better. At the same time, the light can be prevented from shining into the interlayer space from the gap between the cover hole 413 and the light emitting hole 361, the light propagation inside the lamp housing 1 to the brightness detection part 25 is reduced, so that the brightness detection part 25 can more accurately detect the ambient brightness when the light is on; at the same time, the shading ring 362 is embedded in the first light emitting hole 413, so that the shading ring 362 is radially positioned, thereby improving the position accuracy and verticality of the light emitting assembly 3, and avoiding the inclination of the light emitting assembly 3.
[0115] Further, the inner side wall of the shading ring 362 and the side wall of the light emitting hole 361 are integrated together to form a horn-shaped hole, and the hole diameter gradually expands towards the light emitting side.
[0116] In some embodiments, as shown in Figure 12 and Figure 13 , the light emitting assembly 3 further includes a limiting part 33, a lens housing 35 and a shading cover 36 arranged in sequence along a first direction, the first direction being the direction of the light emitting part 32 towards the light emitting hole 361, which has been indicated in Figure 13 ; the side of the first cavity 13 away from the radar hidden part 4 is provided with a partition plate 121, as shown in Figure 17 , the limiting part 33 limits the light emitting part 32 to the partition plate 121, so that the heat generated by the light emitting part 32 is conducted to the side wall of the lamp housing 1 through the partition plate 121, and is dissipated through the side wall of the lamp housing 1. The first cavity 13 is surrounded by the partition plate 121, the side wall of the lamp housing 1 and the circular cover plate 41. An insulating pad 8 made of plastic is arranged 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, the lower surface of the insulating pad 8 is attached to the partition plate 121, and the light emitting circuit board 321, the insulating pad 8 and the partition plate 121 are coated with thermal conductive silicone grease, so that the heat generated by the light emitting part 32 is conducted to the side wall of the lamp housing 1 through the insulating pad 8 and the partition plate 121, and is dissipated through the side wall of the lamp housing 1.
[0117] As shown in Figure 17As shown, the light-emitting circuit board 321 is configured as a square circuit board, the LED lamp bead 322 is arranged at the center of the light-emitting circuit board 321, one right angle of the light-emitting circuit board 321 is provided with a first welding point, and the other right angle opposite to the one right angle is provided with a second welding point and a third welding point. The light-emitting circuit board 321 is connected to the power module 5 through three second wires 38, and the three second wires 38 are welded to the first welding point, the second welding point and the third welding point respectively. The partition plate 121 is provided with a second wire hole 123 for the second wire 38 to pass through.
[0118] Since the lamp shell 1 is made of metal material, the insulating pad 8 serves to improve the insulation performance between the light-emitting circuit board 321 and the partition plate 121, and 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 avoid the lamp shell 1 from being electrified.
[0119] The limiting piece 33 is fixedly connected to the partition plate 121 through two connecting screws 127, the insulating pad 8 is provided with a screw through hole corresponding to the connecting screw 127, the connecting screw 127 passes through the screw through hole and is connected to the partition plate 121, and the light-emitting circuit board 321 and the insulating pad 8 are clamped between the limiting piece 33 and the partition plate 121. The limiting piece 33 is provided with a lamp bead accommodating hole 331 at the center, and the LED lamp bead 322 is accommodated in the lamp bead accommodating hole 331. The side wall of the lamp bead accommodating hole 331 can block the light emitted laterally by the LED lamp bead 322, so as to reduce the light entering the interlayer space. Figure 13 and Figure 16 As shown, the outer edge of the limiting piece 33 extends upward to form a ring-shaped light-blocking wall 332, the lens housing 35 is embedded in the inner side of the ring-shaped light-blocking wall 332, and the side wall of the lens housing 35 and the ring-shaped light-blocking wall 332 form an up-and-down staggered light-blocking structure, which can further block the light from entering the interlayer space, so as to ensure that the brightness detection piece 25 can more accurately detect the ambient brightness when the light is on. Meanwhile, as shown, Figure 17 The ring-shaped light-blocking wall 332 also has a wire pressing function, which can clamp the second wire 38 between the ring-shaped light-blocking wall 332 and the partition plate 121.
[0120] Further, as shown, Figure 16 and Figure 15As shown, one end of the lens housing 35 is clamped with the limiting piece 33, and the other end is sleeved with 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 light outlet hole 361 at one end away from the condenser lens 34, and the anti-dazzle ring 362 is integrally formed on the anti-dazzle cover 36; the lens housing 35 surrounds the side surface of the condenser lens 34 and limits the condenser lens 34. Wherein, the lens housing 35 surrounds the side surface of the condenser lens 34, which can prevent light from the side surface of the condenser lens 34, so as to block the light from entering the interlayer space.
[0121] 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, the clamping ring 341 surrounds the side surface 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, so that the clamping ring 341 is clamped between the positioning ring surface 352 and the clamping protrusions 351, to realize the 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 surface of the condenser lens 34, so that the two are radially positioned, thereby improving the position accuracy of the condenser lens 34.
[0122] Further, as shown in Figure 15 , the side surface of the anti-dazzle cover 36 extends downwardly to form a sleeving ring 363 around the anti-dazzle cover 36, and the sleeving ring 363 is sleeved on the upper edge of the lens housing 35, to realize the radial positioning between the sleeving ring 363 and the lens housing 35. The downwardly extending width of the sleeving ring 363 is relatively wide, so that the sleeving ring 363 not only has the sleeving and limiting effect, but also has the light shielding effect, which can block the light from entering the interlayer space.
[0123] Further, as shown in Figure 16 , the lens housing 35 is provided with a support foot 353 at the bottom, the support foot 353 abuts against the limiting piece 33, to realize the vertical positioning between the lens housing 35 and the limiting piece 33. The lens housing 35 is provided with vertical clamping hooks 354 on both sides, the limiting piece 33 is provided with clamping holes 333, and the two vertical clamping hooks 354 are clamped in the clamping holes 333, to realize the radial positioning and clamping between the lens housing 35 and the limiting piece 33.
[0124] In some embodiments, the lens housing 35 and the anti-dazzle cover 36 are both made of black plastic material, so as to improve the light absorption performance of the anti-dazzle cover 36, enhance the anti-dazzle effect, and reduce the light transmission performance of the lens housing 35 and the anti-dazzle cover 36, so as to reduce the light entering the interlayer space from the light transmission cavity 31, and ensure that the ambient brightness detection member 25 can more accurately detect the ambient brightness when the light is on.
[0125] In some embodiments, as shown in Figure 15 , the condenser lens 34 has an out-light surface 342, and an anti-dazzle cavity 37 is arranged between the out-light surface 342 and the out-light hole 361. The light emitted by the out-light surface 342 is emitted to the outside by the out-light hole 361 after passing through the anti-dazzle cavity 37. The anti-dazzle cavity 37 can be understood as the upper half of the light transmission cavity 31. The anti-dazzle cavity 37 absorbs stray light, which can be understood as light emitted from the out-light surface 342 but not converged to the out-light hole 361. The stray light is reflected multiple times in the anti-dazzle cavity 37, and most of it is finally absorbed by the inner wall of the anti-dazzle cavity 37, thereby reducing the glare effect caused by the stray light. Moreover, the elimination of most stray light makes the light emitted by the out-light hole 361 more regular, which presents a "small hill" shape when the light is parallelly incident on the wall.
[0126] As shown in Figure 13 , the length (L2 in Figure 13 ) of the anti-dazzle cavity 37 in the first direction is greater than 0.6 times the aperture (ΦA in Figure 13 ) of the out-light hole 361, so that the out-light surface 342 is far enough from the out-light hole 361, and the stray light is not easy to be emitted from the out-light hole 361, and the anti-dazzle effect of the anti-dazzle cavity 37 is better. The first direction is the direction of the out-light surface 342 towards the out-light hole. In an embodiment, the length of the anti-dazzle cavity 37 in the first direction is equal to 0.93 times the aperture of the out-light hole 361.
[0127] Further, as shown in Figure 12 , one end of the lamp shell 1 towards the first direction has a first end surface, and the aperture ΦA of the out-light hole 361 is less than 1 / 4 of the outer diameter ΦC of the first end surface. In this embodiment, the aperture of the out-light hole 361 is controlled to make the stray light emitted from the out-light hole 361 less, thereby improving the anti-dazzle effect, and making the light emitted from the out-light hole 361 more regular, which presents a "small hill" shape when the light is parallelly incident on the wall. In an embodiment, the aperture ΦA of the out-light hole 361 is equal to 0.16 times the outer diameter ΦC of the first end surface.
[0128] In some embodiments, as shown in Figure 13As shown, the anti-dazzle cavity 37 is configured as a cylindrical cavity, the aperture diameter ΦA of the light exit hole 361 is smaller than the diameter ΦB of the anti-dazzle cavity 37, so that the light exit hole 361 forms a constricted opening relative to the anti-dazzle cavity 37, making it more difficult for stray light to exit the light exit hole 361, and the anti-dazzle effect is better. In an embodiment, the aperture diameter ΦA of the light exit hole 361 is equal to 13.5 mm, and the diameter ΦB of the anti-dazzle cavity 37 is equal to 22 mm.
[0129] Further, as shown, Figure 15 The light-emitting element 32 is disposed at the incident end of the condenser lens 34, and the end face of the exit end of the condenser lens 34 constitutes the light exit face 342. The anti-dazzle cover 36 is arranged on the exit end of the condenser lens 34 to form the anti-dazzle cavity 37 between the anti-dazzle cover 36 and the light exit face 342. The end of the anti-dazzle cover 36 away from the condenser lens 34 is provided with the light exit hole 361.
[0130] Further, as shown, Figure 10 As shown, the anti-dazzle spotlight 100 is installed in a ceiling hole of a ceiling panel, and the irradiation direction of the lamp housing 1 is vertically downward. The mounting arm 113 has elasticity, and when the anti-dazzle spotlight 100 is installed, the installer first squeezes and shrinks the mounting arm 113 radially, and then installs it into the ceiling hole from bottom to top. The abutment wall 112 abuts against the lower surface of the ceiling panel, and the mounting arm 113 is expanded to the two sides after entering the ceiling hole, so that the mounting arm 113 is clamped in the ceiling hole, thereby realizing the clamping and fixing of the first housing 11 and the ceiling panel. Further, the mounting arm 113 is formed by cutting and bending an iron sheet, and a plastic sleeve is sleeved at the end of the mounting arm 113 to facilitate user operation.
[0131] In some embodiments, as shown, Figures 11-12 Further, the power supply module 5 and the radar module 2 are integrated in the anti-dazzle spotlight 100, and are directly connected between each other, so that the signal transmission is more stable.
[0132] Furthermore, the anti-glare spotlight 100 includes a power module 5 and a power housing 6 disposed outside the first cavity 13. The lamp housing 1 has a partition plate 121 disposed between the power module 5 and the first cavity 13. The power housing 6 is connected to the partition plate 121, forming a second cavity 61 between the power housing 6 and the partition plate 121. The power 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 module 5.
[0133] In some embodiments, such as Figure 12 As shown, the radar module 2 includes a radar circuit board 21, and the power module 5 includes a power board 51. The radar circuit board 21 is connected to the power board 51 via multiple first wires 7. The light-emitting element 32 is connected to the power board 51 via multiple second wires 38. The partition plate 121 has a first wiring hole 122 and a second wiring hole 123. The first wires 7 pass through the first wiring hole 122, and the second wires 38 pass through the second wiring hole 123. The power board 51 controls the brightness of the LED beads 322 via the second wires 38. In one embodiment, as shown... Figure 17 As shown, the LED bead 322 is a dual-color temperature LED bead 322. There are three second wires 38. A light driving unit is provided on the power board 51. The light driving unit is electrically connected to the second wires 38. The light driving unit controls the LED bead 322 to adjust its brightness and color temperature through the second wires 38.
[0134] Furthermore, such as Figure 22 As shown, the first wire 7 has a terminal block 71 at its end, and the power board 51 has a plug-in port 52. The terminal block 71 is plugged into the plug-in port 52 to enable the first wire 7 to conduct electricity with the power board 51. Figure 22 The power module 5 conceals all electronic components except for the power board 51 and the connector port 52. The length of the first wire 7 shown in the figure is for illustrative purposes only and does not represent the actual length. In one embodiment, there are four first wires 7. Four first solder holes 212 are provided near the edge of the radar circuit board 21. One end of the first wire 7 is inserted into the first solder hole 212 and soldered in place. The other end of the first wire 7 is connected to the terminal block 71. Furthermore, the size of the first wiring hole 122 is larger than the horizontal size of the terminal block 71, allowing the terminal block 71 to pass vertically downward through the first wiring hole 122.
[0135] In order to improve the electrical safety and eliminate the risk of electrification of the lamp shell 1, in an embodiment, an insulating sleeve (not shown in the drawings) is sleeved on the four first wires 7, which wraps the four first wires 7 to improve the insulation performance of the first wires 7 and avoid the conduction between the first wires 7 and the lamp shell 1. The second wires 38 are respectively sleeved with insulating sleeves (not shown in the drawings) to improve the insulation performance of the second wires 38 and avoid the conduction between the second wires 38 and the lamp shell 1.
[0136] The structure of the power module 5 is shown in Figure 20 and Figure 21 The power module 5 includes a power board 51 and electronic components arranged on the power board 51. The power board 51 carries strong current circuits and weak current circuits, and the power module 5 converts household alternating current into weak current to provide power for the weak current circuits and the light emitting piece 32. In Figure 20 and Figure 21 , only a part of the electronic components are shown on the power board 51, and all the electronic components are not shown.
[0137] As shown in Figure 20 and Figure 17 , three second welding holes 511 are arranged at one end of the power board 51 close to the edge position, and one end of the three second wires 38 is respectively welded to the three second welding holes 511, and the other end is respectively welded to the first welding point, the second welding point and the third welding point of the light emitting circuit board 321.
[0138] As shown in Figure 20 and Figure 23 , two third welding holes 512 are arranged at the end of the power board 51 away from the second welding holes 511, and the side wall of the power shell 6 is provided with a wire passing hole. The power line 62 is inserted into the power shell 6 from the outside of the power shell 6 through the wire passing hole. The power line 62 is divided into a zero line and a live line inside the power shell 6, and the zero line and the live line are respectively welded to the two third welding holes 512. 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 to avoid the power line 62 from escaping out of the power shell 6. The power shell 6 is respectively provided with anti-escape buckles 63 on both sides of the anti-escape rubber head 621, and the anti-escape buckles 63 are clamped on both sides of the anti-escape rubber head 621 to fix the anti-escape rubber head 621.
[0139] Further, as shown in Figure 21 , Figure 18 and Figure 23As shown, the power panel 51 is provided with two second connecting holes 513, and the power shell 6 is provided with second connecting columns 64 at positions corresponding to the second connecting holes 513. The second connecting columns abut against the lower surface of the power panel 51, and the second connecting columns 64 are connected to the second connecting columns 64 through the second connecting holes 513 by means of second screws 641, so that the power panel 51 is fixedly connected to the power shell 6. It is worth noting that the two second connecting holes 513 are respectively arranged at 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.
[0140] Further, as shown in Figures 17-19 Further, the side surface 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 surface of the power shell 6, and is used for 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, and the positioning rib 126 is protruded at a position corresponding to the positioning groove 66, the positioning rib 126 is embedded in the positioning groove 66 to achieve the circumferential positioning between the power shell 6 and the first shell 11. The mutual 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 the assembly process, and to improve the assembly efficiency.
[0141] In some embodiments, as 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 by 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 form the first cavity 13, and the first shell 11 and the second shell 12 are made of aluminum alloy. 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 by thread through relative rotation, so that they are fixedly connected. Further, the arc-shaped positioning wall 125 is integrally formed on the second shell 12.
[0142] 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 anti-dazzle spotlight 100 provided by the utility model is more complex in assembly, and the assembly steps are as follows: Figure 12As shown, first, the power module 5 is fixed inside the power shell 6, the anti-dropping rubber head 621 is clamped to the anti-dropping buckle 63, and the power cord 62 is welded to the power board 51. Then, the first wire 7 and the second wire 38 are respectively inserted 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 inserted into the power board 51 through the wiring terminal 71; one end of the second wire 38 is welded to the power board 51, and the other end is welded to the light-emitting piece 32. Subsequently, the power shell 6 is fixedly installed on the partition plate 121, and the power module 5 is locked inside the second cavity 61. Next, the limiting piece 33 is installed on the partition plate 121, and the limiting piece 33 limits the light-emitting piece 32 on the partition plate 121, the condenser lens 34 is clamped to the lens shell 35, the lens shell 35 is clamped to the limiting piece 33, and the anti-dazzle cover 36 is sleeved on the top of the lens shell 35. Next, the first shell 11 is sleeved outside the first wire 7, and the radar circuit board 21 is installed on the radar hiding piece 4 through the first shell 11. Finally, the first shell 11 is rotatably connected to the second shell 12, the radar hiding piece 4 is clamped to the first shell 11, and the assembly is completed. In this installation process, thanks to the combination of the first shell 11 and the second shell 12 of the lamp shell 1, the first shell 11 can be kept in an inclined state during the installation of the radar circuit board 21 on the radar hiding piece 4, so as to reserve more space for the installation of the radar circuit board 21 on the radar hiding piece 4 within a limited length, which is beneficial to improve the assembly rate. After the radar circuit board 21 is installed on the radar hiding piece 4, the first shell 11 is rotatably connected to the second shell 12.
[0143] Further, as shown in Figure 5 and Figure 4 , the radar hiding piece 4 comprises the circular cover plate 41 and four connecting clamps 45 arranged on the back of the circular cover plate 41, and the four connecting clamps 45 are uniformly distributed circumferentially. The inner wall of the first shell 11 is provided with a clamping groove 111 around the circumference. When the radar hiding piece 4 is installed on the first shell 11, the back of the circular cover plate 41 abuts against the first shell 11, and the connecting clamps 45 are clamped to the clamping groove 111. Further, to prevent the circular cover plate 41 from being disassembled by the user, the connecting clamps 45 are brushed with glue before being clamped to the clamping groove 111 during the installation of the circular cover plate 41.
[0144] In some embodiments, the power shell 6 is integrally formed of plastic material, and the power board 51 is provided with a wireless communication module 53. The plastic material of the power shell 6 does not shield the wireless signal, thereby ensuring the strength of the wireless signal. As shown in Figure 21 , the wireless communication module 53 comprises a communication antenna 531, and the power board 51 is provided with a notch at a position corresponding to the communication antenna 531, so as to prevent the power board 51 from shielding the communication antenna 531, thereby improving the strength of the wireless signal.
[0145] Furthermore, since the second housing 12 is made of aluminum alloy, it has a shielding effect on wireless signals. In this embodiment, to reduce the shielding effect of the second housing 12, such as... Figure 19 As shown, the arc-shaped positioning wall 125 of the second housing 12 does not encircle the entire circumference, but instead has anti-shielding notches 1251 on both sides. The wireless communication module 53 is positioned corresponding to one of the anti-shielding notches 1251, and the wireless signal is transmitted outward from the anti-shielding notch 1251 to reduce the shielding effect of the arc-shaped positioning wall 125. Furthermore, the communication antenna 531 of the wireless communication module 53 faces outward (e.g., ...). Figure 20 (As shown), further enhances wireless signal strength.
[0146] In existing technology, spotlights emit stray light that shines outwards beyond the beam angle range, causing glare if this stray light excessively illuminates the user's eyes. To reduce this glare, according to a second aspect of this invention, such as... Figures 1-23 As shown, an anti-glare spotlight is also provided, characterized in that it includes a lamp housing 1 and a light-emitting component 3 disposed inside the lamp housing 1. The light-emitting component 3 includes a light-emitting surface 342, a light-emitting hole 361, and an anti-glare cavity 37 disposed between the light-emitting surface 342 and the light-emitting hole. The light emitted from the light-emitting surface 342 passes through the anti-glare cavity 37 and is emitted to the outside through the light-emitting hole. The length of the anti-glare cavity 37 in a first direction is greater than 0.6 times the diameter of the light-emitting hole. The first direction is the direction from which the light-emitting surface 342 faces the light-emitting hole.
[0147] Wherein, the length of the anti-glare cavity 37 in the first direction is Figure 13 In L2, the aperture of the light-emitting aperture 361 is... Figure 13 In this configuration, ΦA and L2 are greater than 0.6 times ΦA, ensuring that the light-emitting surface 342 is sufficiently far from the light-emitting aperture 361. This prevents stray light from easily escaping from the light-emitting aperture 361, and most of the stray light is blocked inside the anti-glare cavity 37, thereby reducing the glare effect caused by stray light. The condenser lens 34 focuses the light towards the light-emitting aperture 361, allowing most of the light to exit from the aperture. Light that does not converge to the light-emitting aperture 361 can be considered stray light.
[0148] In one embodiment, the length of the anti-glare cavity 37 in the first direction is equal to 0.93 times the aperture of the light-emitting aperture 361.
[0149] Furthermore, such as Figure 12 As shown, the end of the lamp housing 1 facing the first direction has a first end face, and the aperture ΦA of the light-emitting hole is less than 1 / 4 of the outer diameter ΦC of the first end face.
[0150] In some embodiments, such asFigure 13 As shown, the anti-dazzle cavity 37 is configured as a cylindrical cavity, and the aperture diameter ΦA of the light exit hole is smaller than the diameter ΦB of the anti-dazzle cavity 37.

[0151] In some embodiments, as shown in Figure 2 As shown, one end of the lamp housing 1 in the first direction is an open end, which is provided with a circular cover plate 41. The circular cover plate and the lamp housing 1 form a first cavity 13, and the light emitting assembly 3 is arranged inside the first cavity 13. A cover plate hole 413 is formed in the center of the circular cover plate, and the light exit hole is coaxially arranged with the cover plate hole. The light emitted by the light exit surface 342 is emitted outward through the light exit hole and the cover plate hole.
[0152] Further, as shown in Figure 15 The light emitting assembly 3 includes a condenser lens 34 and an anti-dazzle cover 36. The condenser lens 34 includes an incident end and an exit end. The end face of the exit end constitutes the light exit surface 342. The anti-dazzle cover 36 is arranged on the exit end of the condenser lens 34 to form the anti-dazzle cavity 37 between the anti-dazzle cover 36 and the light exit surface 342. An end of the anti-dazzle cover 36 away from the condenser lens 34 is provided with the light exit hole.
[0153] Further, as shown in Figure 15 and Figure 13 The anti-dazzle cover 36 extends an anti-dazzle ring 362 around the light exit hole in the light exit direction. The circular cover plate abuts against the anti-dazzle cover 36, and the anti-dazzle ring is embedded in the cover plate hole.
[0154] In some embodiments, as shown in Figure 15 and Figure 14 The light emitting assembly 3 further includes a light emitting member 32 arranged on the incident end of the condenser lens 34. The light emitted by the light emitting member 32 is converged by the condenser lens 34 toward the light exit hole and is emitted through the light exit hole.
[0155] Further, as shown in Figure 13 , Figure 15 and Figure 16 The light emitting assembly 3 further includes a limiting member 33 and a lens housing 35. The limiting member 33, the lens housing 35, and the anti-dazzle cover 36 are arranged in sequence along a first direction, which is the direction of the light emitting member 32 toward the light exit hole. The limiting member 33 is used to limit the light emitting member 32. One end of the lens housing 35 is connected to the limiting member 33, and the other end is sleeved by the anti-dazzle cover 36. The lens housing 35 surrounds the side surface of the condenser lens 34 and limits the condenser lens 34.
[0156] In some embodiments, the anti-glare shield 36 is black.
[0157] In some embodiments, such as Figures 2-5 As shown, a radar module 2 is installed inside the circular cover plate, and the radar waves emitted by the radar module 2 pass through the circular cover plate and are transmitted outwards; as Figures 11-12 As shown, the anti-glare spotlight also includes a power module 5 and a power housing 6 disposed outside the first cavity 13. The lamp housing 1 includes a partition plate 121 disposed between the power module 5 and the first cavity 13. The power housing 6 is connected to the partition plate 121, forming a second cavity 61 between the power housing 6 and the partition plate 121. The power 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 module 5.
[0158] The structure of the anti-glare spotlight 100 is the same as that of the anti-glare spotlight 100 provided in the first aspect above. The technical details of the lamp housing 1, light-emitting component 3, anti-glare cavity 37, circular cover plate, focusing lens 34, anti-glare cover 36, power module 5, etc. have been described in detail above and will not be repeated here.
[0159] According to a third aspect of this utility model, a smart spotlight without human body sensing function (not shown in the accompanying drawings) is also provided. This is based on the aforementioned anti-glare spotlight 100, but without the radar module 4, light guide 44, first wire 7, wiring terminal 71, plug-in port 52, and the circuitry related to the radar module 4. The smart spotlight can receive wireless signals and control the light-emitting element to light up or turn off according to the wireless signals.
