Description

Technical Field

[0001] This disclosure relates to the fields of lighting technology and radar sensing technology, and in particular to a microwave radar sensing lighting fixture and a microwave radar sensing lighting system. Background Technology

[0002] Microwave radar sensors have been widely used in the field of smart lighting due to their high sensitivity, strong anti-interference ability, and insensitivity to ambient light.

[0003] Currently, the radar component of some microwave radar sensing lights is usually integrated with the main body of the light fixture, such as embedded radar sensing downlights on the market and the existing patent CN205174130U, a built-in LED panel light based on microwave radar sensing. This leads to the following problems:

[0004] 1. The radar component is integrated with the main body of the lamp. The installation of the radar component requires overall debugging, which makes the radar component less compatible with more types of lamps, thereby increasing the installation difficulty and time cost.

[0005] 2. Taking embedded radar sensor downlights on the market as an example, when the radar component of some lamps is embedded inside the housing, such as the edge of the lampshade, the base, or the lamp post as a whole, if the radar component is damaged, removing the radar component may damage the appearance of the housing, thereby compromising the integrity of the lamp. Taking the existing patent CN205174130U as an example, since it uses an integrated microwave radar sensor dimming power supply, when the microwave radar sensor part is damaged, it will affect the entire dimming power supply, requiring the replacement of the entire power supply. Either of the above two situations will increase maintenance costs. Utility Model Content

[0006] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a microwave radar sensing lighting fixture and microwave radar sensing lighting system that can be adapted to various types of lighting fixtures without replacing the entire structure.

[0007] The purpose of this disclosure is achieved through the following technical solution:

[0009] In one embodiment, the light source assembly includes a power board, an illumination board, and a light-transmitting element. The power board is electrically connected to the illumination board. The power board, the illumination board, and the light-transmitting element are all located within the accommodating cavity and are all connected to the lamp housing. The light-transmitting element is disposed adjacent to the light outlet, and the light-emitting portion of the illumination board is disposed facing the light-transmitting element. The radar sensing module is electrically connected to the radar control terminal of the power board.

[0010] In one embodiment, the lamp housing includes a housing body and a pre-installed housing, the pre-installed housing being detachably installed on the housing body. The accommodating cavity includes a first accommodating cavity and a second accommodating cavity, the first accommodating cavity being disposed within the housing body, the second accommodating cavity being disposed within the pre-installed housing, and the second accommodating cavity, the first accommodating cavity, and the light outlet being sequentially connected. The power board, the lighting board, and the light-transmitting element are all located within the first accommodating cavity, and the power board, the lighting board, and the light-transmitting element are all connected to the housing body. The radar sensing module is located within the second accommodating cavity and connected to the pre-installed housing, and the sensing end of the radar sensing module is positioned facing the bottom of the pre-installed housing.

[0011] In one embodiment, the microwave radar-sensing lighting fixture further includes a magnetic component connected to the fixture housing.

[0012] In one embodiment, a pre-installation area is formed between the light-transmitting element, the lamp housing, and the lighting panel. The pre-installation area is located within the accommodating cavity and is disposed adjacent to the light outlet. The radar sensing module is disposed on the lighting panel, and the sensing end of the radar sensing module is disposed adjacent to the light outlet.

[0013] In one embodiment, the microwave radar-sensing lighting fixture further includes a pre-installed torsion spring. The fixture housing has a pre-installed protrusion and a mounting boss. The pre-installed protrusion passes through the hollow portion of the pre-installed torsion spring, and the end of the pre-installed torsion spring abuts against the mounting boss.

[0014] In one embodiment, the lamp housing includes a back cover, a pre-installed lamp body, and a reflector. The back cover is connected to the pre-installed lamp body. The accommodating cavity is disposed in the back cover and the pre-installed lamp body, and the light outlet is disposed in the pre-installed lamp body. The reflector is located in the accommodating cavity and is connected to the pre-installed lamp body, and the opening of the reflector faces the light outlet.

[0015] In one embodiment, the power board and the lighting board are both disposed on the reflector cup, the lighting board is disposed facing the light outlet, the power board is disposed away from the light-transmitting element, the radar sensing module is disposed on the lighting board, and the sensing end of the radar sensing module is disposed facing the light-transmitting element.

[0016] In one embodiment, the pre-installed lamp body includes a lamp body body and a straight torsion spring. The outside of the lamp body body is provided with a pre-installed locking post, which passes through the hollow part of the straight torsion spring.

[0017] A microwave radar sensing lighting system includes the microwave radar sensing lighting fixture described in any one of the above embodiments.

[0018] Compared with the prior art, this disclosure has at least the following advantages:

[0019] 1. The microwave radar sensing lighting fixtures mentioned above have a radar sensing module, in which the radar sensor is used to detect the movement signals of the human body or objects and transmit the collected data to the signal processing module. Finally, the signal processing module outputs the signal data to control the lighting state of the light source components, thereby reducing the high energy consumption caused by the lamps being powered on for a long time.

[0020] 2. The radar sensor module can be used in many types of lighting fixtures, such as magnetic lights, grille lights, and downlights, and has suitable installation positions. When used in magnetic lights, the pre-installed housing is detachable and installed on the main body of the housing, and the radar sensor module is located in the pre-installed housing. Therefore, the radar sensor module can be replaced by removing and replacing the pre-installed housing. When used in grille lights and downlights, the radar sensor module is located on the lighting board, rather than being integrated with the power board or lighting board. In this way, if the radar component is damaged, only the radar sensor module needs to be replaced, without affecting the performance of other components. This achieves a quick installation effect without replacing the entire component or even the entire lighting fixture, reducing the maintenance cost of the radar component.

[0021] 3. Regardless of the type of lighting fixture the radar sensing module is applied to, the radar sensing module is always located inside the fixture housing, achieving a concealed installation effect and not affecting the overall appearance of the lighting fixture.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0036] Please see Figures 1 to 5This invention relates to a microwave radar-sensing lighting fixture 10, which includes a fixture housing 100, a light source assembly 200, and a radar sensing module 300. The fixture housing 100 has a connected accommodating cavity 101 and a light outlet 102. The light source assembly 200 and the radar sensing module 300 are both located in the accommodating cavity 101, and the light emission direction of the light source assembly 200 is located at the light outlet 102. The light source assembly 200 is connected to the fixture housing 100, and the radar sensing module 300 is electrically connected to the light source assembly 200. The sensing end of the radar sensing module 300 is positioned facing the bottom of the fixture housing 100.

[0037] like Figure 8 As shown, the radar sensing module 300 includes a radar sensor 310, a signal processing module 320, and a communication module 330. The radar sensor 310 is used to detect movement signals, the signal processing module 320 is used to acquire radar signals and output commands, the sensing output terminal of the radar sensor 310 is electrically connected to the data acquisition terminal of the signal processing module 320, the command output terminal of the signal processing module 320 is electrically connected to the light output control terminal of the light source assembly 200, and the communication terminal of the communication module 330 is electrically connected to the data transmission terminal of the signal processing module 320. It can be understood that a movement signal refers to the signal corresponding to the movement of a human body or object; that is, a signal confirmed by whether a human body or object is moving. When the radar sensor 310 detects a human body or object that is not moving, or no matter present, the acquired signal is a low-level signal. Subsequently, the signal processing module 320 outputs a control command to the light source assembly 200 based on the corresponding signal, at which point the light source assembly 200 enters a low-power mode. Conversely, when a moving human body or object is detected, the acquired signal is a high-level signal, at which point the light source assembly 200 provides normal illumination.

[0038] The aforementioned microwave radar-sensing lighting fixture 10 includes a radar sensing module 300, where a radar sensor 310 detects movement signals of a human body or object and transmits the collected data to a signal processing module 320. The signal processing module 320 then outputs the signal data to control the lighting state of the light source assembly 200, thereby reducing high energy consumption caused by prolonged power-on of the fixture. Furthermore, the communication module 330 integrates a 2.4GMesh communication protocol for remote operation by the user or communication between multiple lighting fixtures. Thus, when the radar sensing module 300 needs upgrading, it can be upgraded remotely via OTA (Over-the-Air Technology). The radar sensor 310 uses a 5.8GHz or 24GHz radar chip to detect movement signals of a human body or object.

[0039] Furthermore, such as Figure 2 , Figure 4 or Figure 5 As shown, the light source assembly 200 includes a power board 210, an illumination board 220, and a light-transmitting element 230. The power board 210 is electrically connected to the illumination board 220. The power board 210, the illumination board 220, and the light-transmitting element 230 are all located within the accommodating cavity 101, and are all connected to the lamp housing 100. The light-transmitting element 230 is disposed adjacent to the light outlet 102. The light-emitting portion of the illumination board 220 is disposed facing the light-transmitting element 230 so that the light emitted by the illumination board 220 passes through the light-transmitting element 230. The radar sensing module 300 is electrically connected to the radar control terminal of the power board 210 so that the radar sensing module 300 indirectly controls the illumination state of the illumination board 220 according to the radar signal state. In this embodiment, the instruction output terminal of the signal processing module 320 is electrically connected to the light output control terminal of the power board 210, so that the signal processing module 320 indirectly controls the light emission state of the lighting board 220 according to the signal data collected by the radar sensor 310.

[0040] In another embodiment, the power board 210 is used to supply power to the lighting board 220. For example, the input terminal of the power board 210 is used to connect to the power supply.

[0041] In addition, the radar sensing module 300 can be used in many types of lighting fixtures, such as magnetic lights, grille lights, downlights, etc. The following examples illustrate the application of the radar sensing module 300 to the corresponding lighting fixtures.

[0042] For magnetic lights, in one embodiment, such as Figure 1 and Figure 2As shown, the lamp housing 100 includes a housing body 110 and a pre-installed housing 120. The pre-installed housing 120 is detachably installed on the housing body 110. The accommodating cavity 101 includes a first accommodating cavity 1011 and a second accommodating cavity 1012. The first accommodating cavity 1011 is disposed in the housing body 110, and the second accommodating cavity 1012 is disposed in the pre-installed housing 120. The second accommodating cavity 1012, the first accommodating cavity 1011, and the light outlet 102 are sequentially connected. The power board 210, the lighting board 220, and the light-transmitting element 230 are all located in the first accommodating cavity 1011, and the power board 210, the lighting board 220, and the light-transmitting element 230 are all connected to the housing body 110. The radar sensing module 300 is located in the second accommodating cavity 1012 and connected to the pre-installed housing 120. The sensing end of the radar sensing module 300 is arranged facing the bottom of the pre-installed housing 120. It is understandable that when the pre-installed housing 120 is detachably installed on the housing body 110, since the radar sensing module 300 is located inside the pre-installed housing 120, when the radar sensing module 300 needs to be replaced, only the pre-installed housing 120 needs to be removed to replace the radar sensing module 300. Replacement does not affect other components of the lamp, thus achieving the effect of replacing the radar component separately without replacing the entire component or even the entire lamp. In this embodiment, the light-transmitting element 230 is a light-transmitting panel.

[0043] like Figure 3 As shown, in one embodiment, the microwave radar-sensing lighting fixture 10 further includes a magnetic assembly 400, which is connected to the fixture housing 100 to form a magnetic lamp. When installing the magnetic lamp, its magnetic blocks can magnetically attract it onto a mounting magnetic track. Furthermore, the magnetic assembly 400 has a snap-fit ​​portion 401 and an electrical connection portion 402 on its outer side. The snap-fit ​​portion 401 is used to engage with the snap-fit ​​portion of the magnetic track to enhance the connection strength between the magnetic track and the magnetic lamp. The electrical connection portion 402 is used to electrically connect to the wire portion of the magnetic track so that the magnetic lamp illuminates normally when powered on.

[0044] When the aforementioned radar sensing module 300 is applied to a magnetic lamp, since the pre-installed housing 120 is detachably installed on the housing body 110 and the radar sensing module 300 is located in the pre-installed housing 120, the radar sensing module 300 can be replaced by replacing the pre-installed housing 120. In this way, when the radar component is damaged, only the radar sensing module 300 needs to be replaced, without affecting the performance of other components. Thus, there is no need to replace the entire component or even the entire lamp.

[0045] For grille lights, in one embodiment, such as Figure 3 and Figure 4As shown, a pre-installation area 100a is formed by the light-transmitting element 230, the lamp housing 100, and the lighting panel 220. The pre-installation area 100a is located in the receiving cavity 101 and is positioned near the light outlet 102. The radar sensing module 300 is mounted on the lighting panel 220, and the sensing end of the radar sensing module 300 is positioned near the light outlet 102 to prevent interference between the radar sensing module 300 and the lighting panel 220. If the radar component is damaged, only the radar sensing module 300 needs to be replaced, without replacing the entire component or even the entire lamp.

[0046] In this embodiment, the light-transmitting element 230 is a light-transmitting cover, and there are multiple light-transmitting covers. The pre-installation area 100a is formed by two adjacent light-transmitting covers, the lighting panel 220 and the lamp housing 100.

[0047] like Figure 3 and Figure 4 As shown, in one embodiment, the microwave radar sensing lighting fixture 10 further includes a pre-installed torsion spring 500. The fixture housing 100 is provided with a pre-installed protrusion 100A and a mounting protrusion 100B. The pre-installed protrusion 100A passes through the hollow part of the pre-installed torsion spring 500, and the end of the pre-installed torsion spring 500 abuts against the mounting protrusion 100B, thereby forming a grid light. In this way, when installing the grid light, the main body of the fixture is embedded into the main body of the building until the mounting protrusion 100B abuts against the ceiling. During this period, the pre-installed torsion spring 500 has a certain elastic potential energy, so that the pre-installed torsion spring 500 abuts against the installation point of the main body of the building, thereby keeping the mounting protrusion 100B in contact with the ceiling.

[0048] When the aforementioned radar sensing module 300 is applied to a grille light, since the radar sensing module 300 is mounted on the lighting panel 220, there is no interference between the radar sensing module 300 and the lighting panel 220. When the radar component is damaged, only the radar sensing module 300 needs to be replaced, without replacing the entire component or even the entire light fixture.

[0049] For downlights, in one embodiment, such as Figure 5 and Figure 6As shown, the lamp housing 100 includes a rear cover 130, a pre-installed lamp body 140, and a reflector 150. The rear cover 130 is connected to the pre-installed lamp body 140. A receiving cavity 101 is disposed within the rear cover 130 and the pre-installed lamp body 140, and a light outlet 102 is disposed within the pre-installed lamp body 140. The reflector 150 is located in the receiving cavity 101 and is connected to the pre-installed lamp body 140, with the opening of the reflector 150 facing the light outlet 102. Furthermore, a power board 210 and a lighting board 220 are both disposed within the receiving cavity 130. On the reflector cup 150, the lighting panel 220 is positioned facing the light outlet 102, the power board 210 is positioned away from the light-transmitting element 230, and the radar sensor module 300 is mounted on the lighting panel 220 with its sensing end facing the light-transmitting element 230. This ensures that the radar sensor module 300 and the lighting panel 220 in the downlight will not interfere with each other. If the radar component is damaged, only the radar sensor module 300 needs to be replaced, without replacing the entire component or even the entire lamp. In this embodiment, the light-transmitting element 230 is a 4-inch light-transmitting plate.

[0050] like Figure 6 and Figure 7 As shown, in one embodiment, the pre-installed lamp body 140 includes a lamp body 141 and a straight torsion spring 142. The lamp body 141 has a pre-installed bracket on its outer side, and pre-installed bracket posts 1411 protrude from both sides of the pre-installed bracket. The pre-installed bracket posts 1411 pass through the hollow part of the straight torsion spring 142 to form an embedded downlight. The embedded downlight is then used to be embedded in the building structure. Similarly, during installation, the straight torsion spring 142 has a certain elastic potential energy, so that part of the structure of the pre-installed lamp body 140 remains in contact with the ceiling.

[0051] When the aforementioned radar sensing module 300 is applied to a grille light, since the radar sensing module 300 is mounted on the lighting panel 220, there is no interference between the radar sensing module 300 and the lighting panel 220. When the radar component is damaged, only the radar sensing module 300 needs to be replaced, without replacing the entire component or even the entire light fixture.

[0052] This disclosure also provides a microwave radar sensing lighting system, including the microwave radar sensing lighting fixture 10 of any of the above embodiments.

[0053] Compared with the prior art, this disclosure includes, but is not limited to, the following advantages:

[0054] 1. The microwave radar sensing lighting fixture 10 described above has a radar sensing module 300, wherein the radar sensor 310 is used to detect the movement signal of a human body or object and transmit the collected data to the signal processing module 320. Finally, the signal processing module 320 outputs the signal data to control the lighting state of the light source component 200, thereby reducing the high energy consumption caused by the long-term power supply of the lighting fixture.

[0055] 2. The radar sensing module 300 can be used in many types of lighting fixtures, such as magnetic lights, grille lights, and downlights, and has suitable installation positions. When applied to magnetic lights, since the pre-installed housing 120 is detachably installed on the housing body 110, and the radar sensing module 300 is set in the pre-installed housing 120, the radar sensing module 300 can be replaced by replacing the pre-installed housing 120. When applied to grille lights and downlights, the radar sensing module 300 is set on the lighting board 220, rather than integrating the radar sensing module 300 with the power board 210 or the lighting board 220. In this way, when the radar component is damaged, only the radar sensing module 300 needs to be replaced, without affecting the performance of other components. This achieves the effect of quick installation without replacing the entire component or even the entire lighting fixture, reducing the maintenance cost of the radar component.

[0056] 3. Regardless of the type of lighting fixture to which the radar sensor module 300 is applied, the radar sensor module 300 is always located inside the lighting fixture housing 100, achieving a concealed installation effect and not affecting the overall appearance of the lighting fixture.

[0057] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
