Description

Technical Field

[0001] This utility model relates to the field of intelligent lighting technology, and in particular to a panel light with an external sensor. Background Technology

[0002] Sensor panel lights are lighting fixtures that automatically control their switching on and off by sensing changes in the external environment. They typically have built-in infrared, sound, or light sensors that can automatically turn on or off when specific conditions are detected. Human body sensors can automatically turn on the lights when someone is detected approaching, improving ease of use and energy efficiency.

[0003] A search revealed that CN220958362U discloses a lamp panel with a quick-release structure and a built-in sensor, including a lamp panel body and a sensing component. The sensing component includes a sensor and a fixing position disposed on the sensor. The sensor is connected to a mounting hole on one side of the lamp panel body through the fixing position and screws. A wire is led out from one end of the sensor, and a female connector is formed at one end of the wire. A wiring hole is provided on the lamp panel body near the sensor. A terminal wire is provided in the wiring hole. One end of the terminal wire is connected to an internal component of the lamp panel body, and the other end passes through the wiring hole to form a male connector that is plugged into the female connector.

[0004] This design has flaws. The built-in sensor design makes it difficult to install and replace the sensor. With the rapid upgrading of sensor technology, if lighting users want to replace the sensor with a new one, they need to disassemble the complex internal structure of the lighting fixture, making the sensor replacement difficult and increasing maintenance costs. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a panel light with an external sensor, which aims to improve the problem of difficulty in replacing the sensor in traditional panel lights with built-in sensors.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a panel light with an external sensor, comprising a panel light body, an LED light board fixedly connected inside the panel light body, an optical diffuser plate and an anti-glare plate fixedly connected inside the panel light body, the optical diffuser plate being located on the upper surface of the anti-glare plate, the optical diffuser plate and the anti-glare plate together forming a light-emitting plate, a sealing strip fixedly connected to the lower surface of the anti-glare plate, an integrated face frame fixedly connected to the lower surface of the sealing strip, a driving assembly provided on the back of the panel light body, a plastic frame installed on the outer side of the panel light body, and a sensor body installed on the plastic frame, the sensor body being used to sense human movement.

[0007] Through the above technical solution: the main body of the panel light serves as the core supporting structure of the entire panel light, providing an installation foundation and physical protection for other components. It stably supports internal components such as the LED light panel, optical diffuser plate, and anti-glare plate, while resisting possible external impacts, dust, and moisture, ensuring the normal operation of internal components. It is responsible for evenly diffusing the light emitted by the LED light panel, increasing the coverage and uniformity of the lighting. The design of two light-emitting surfaces helps reduce the difference in brightness within the illuminated area, providing softer and more comfortable light to meet the lighting needs of different scenarios. The integrated frame enhances the overall structural strength of the panel light and protects the internal components. By placing the sensor body externally and installing it on the plastic frame, replacement can be done without disassembling the internal structure of the light fixture, only by manipulating the frame, significantly reducing maintenance difficulty and cost, and solving the problem of complex replacement of traditional built-in sensors.

[0008] As a further description of the above technical solution:

[0009] The driving component includes a driving power supply, which is electrically connected to the sensor body and the LED light panel.

[0010] Through the above technical solution: the driver power supply is fixed on the upper surface of the panel light body, providing a stable power source for the entire panel light. The driver power supply and the sensor body cooperate with each other. The driver power supply provides the sensor body with the power required for operation, enabling it to operate normally and accurately sense environmental changes. The sensor body, based on the sensing results, controls the power supply of the driver power supply to the LED light panel, realizing the intelligent dimming, switching and other functions of the lamp.

[0011] As a further description of the above technical solution:

[0012] The plastic frame includes an upper frame and a lower frame, which are located on the upper and lower surfaces of the integrated face frame, respectively. The upper frame and the lower frame clamp the integrated face frame. The upper frame is provided with a mating post, and the lower frame is provided with a mating hole. The mating post is inserted into the mating hole.

[0013] The above technical solution involves the mating column and mating hole working together to form an organic whole among the internal components of the lamp, ensuring the accurate relative positions of each component.

[0014] As a further description of the above technical solution:

[0015] A second sealing strip is also provided between the upper frame and the lower frame.

[0016] Through the above technical solution, the sealing strip can effectively fill the gap between the upper frame and the lower frame, forming a sealing barrier to prevent dust, moisture and other external impurities from entering the lamp.

[0017] As a further description of the above technical solution:

[0018] The upper frame is provided with a fastening buckle facing the lower frame, and the lower frame is provided with a mounting groove with a through hole. When the upper frame and the lower frame are assembled, the fastening buckle passes through the through hole of the mounting groove to lock the upper frame and the lower frame.

[0019] The above technical solution involves the buckle passing through the mounting slot through the hole and forming a four-point contact lock with the inner wall of the lower frame. This ensures that the upper and lower frames remain firmly connected under vibration or external force impact, preventing the light-emitting panel from shifting or the sensor from falling off due to frame separation.

[0020] As a further description of the above technical solution:

[0021] The inner side of the integrated face frame protrudes to form a mounting plate, and the upper frame and lower frame are respectively connected to the mounting plate.

[0022] The above technical solution uses a mounting plate to support the upper and lower frames, greatly enhancing the stability of the overall structure of the lighting fixture.

[0023] As a further description of the above technical solution:

[0024] The mounting plate has mounting holes formed on both the top and bottom, and the sensor body passes through the mounting holes and is detachably mounted on the mounting plate.

[0025] The main function of the mounting holes described above is to facilitate the installation of light fixtures. Through these holes, screws, bolts, and other connectors can be used to fix the panel light to the ceiling, wall, or other installation locations, making the installation process simpler, faster, and improving installation efficiency.

[0026] As a further description of the above technical solution:

[0027] The mounting plate has mounting holes formed on both the top and bottom, and the sensor body passes through the mounting holes and is detachably mounted on the mounting plate.

[0028] With the above technical solution, the mounting holes of the mounting plate are designed to be detachably connected to the sensor body, allowing for disassembly and assembly without tools. The maintenance time for a single operation is ≤1 minute, which is a significant improvement over the traditional built-in screw fixing method.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, by placing the sensor body externally and using a plastic frame, it is easier to install and replace the sensor from the outside. Compared with traditional panel lights with built-in sensors, the sensor can be replaced without disassembling the complex internal structure of the light fixture, which reduces maintenance costs and difficulty, improves the convenience of use, and solves the problem of the difficulty in replacing sensors.

[0031] 2. In this utility model, by installing a plastic frame around the sensor assembly, a smaller volume and a wall surface that is nearly perpendicular to the light-emitting surface can be achieved, reducing the impact on the brightness of the optical diffuser plate and the anti-glare plate, thereby making the light emission uniform and shadow-free, and the lighting effect more beautiful. This improves the overall lighting quality of the panel light and can better meet the lighting needs of various places.

[0032] 3. In this utility model, the plastic frame is used to cooperate with the base and is inlaid on the integrated frame of the panel light body and the face frame. This not only makes the structure stable, but also presses and fixes the optical diffuser plate and the anti-glare plate, ensuring that the propagation and distribution of light are more reasonable.

[0033] 4. In this utility model, the second sealing strip and the first sealing strip work together to enable the light-emitting surface to achieve an IP44 waterproof and dustproof rating, effectively protecting the electronic components inside the lamp and extending the lamp's service life. It can also work normally and stably even in harsh environments. Attached Figure Description

[0041] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0042] Reference Figures 1-3 An embodiment of this utility model provides: a panel light with an external sensor, including a panel light body 1, an LED light board 2 fixedly connected inside the panel light body 1, an optical diffuser plate 3 and an anti-glare plate 4 fixedly connected inside the panel light body 1, the optical diffuser plate 3 being located on the upper surface of the anti-glare plate 4, the optical diffuser plate 3 and the anti-glare plate 4 together forming a light-emitting plate, a sealing strip 5 fixedly connected to the lower surface of the anti-glare plate 4, an integrated face frame 6 fixedly connected to the lower surface of the sealing strip 5, a driving component 7 being provided on the back of the panel light body 1, a plastic frame 8 being installed on the outer side of the panel light body 1, and a sensor body 72 being installed on the plastic frame 8, the sensor body 72 being used to sense the movement of a human body;

[0043] Specifically, the optical diffuser plate 3 is located on the upper surface of the anti-glare plate 4 and together with the anti-glare plate 5, forms a light-emitting plate. It is responsible for evenly diffusing the light emitted by the LED light panel, increasing the coverage and uniformity of the lighting, reducing the difference in brightness within the lighting area, providing softer and more comfortable light, and meeting the lighting needs of different scenarios. The sealing strip 5 is used to fill gaps and prevent dust, moisture and other external impurities from entering the interior of the lamp.

[0044] Reference Figures 1-3 The driving component 7 includes a driving power supply 71, which is electrically connected to the sensor body 72 and the LED light panel 2.

[0045] Specifically, the driving power supply 71 is electrically connected to the sensor body 72 and the LED light panel 2, providing a stable power source for the entire panel light; the driving power supply 71 provides working power to the sensor body 72, and the sensor body 72 controls the power supply of the driving power supply 71 to the LED light panel 2 according to the sensing result.

[0046] Reference Figures 2-4 The plastic frame 8 includes an upper frame 81 and a lower frame 82, which are located on the upper and lower surfaces of the integrated face frame 6, respectively. The upper frame 81 and the lower frame 82 clamp the integrated face frame 6. The upper frame 81 is provided with a mating post 9, and the lower frame 82 is provided with a mating hole 13. The mating post 9 is inserted into the mating hole 13. A sealing strip 2 11 is also provided between the upper frame 81 and the lower frame 82.

[0047] Specifically, the upper frame 81 and lower frame 82 of the plastic frame 8 are respectively clamped to the upper and lower surfaces of the integrated face frame 6. The cylindrical protrusions of the mating column 9 and the corresponding recesses of the mating hole 13 engage, so that the plastic frame 8 and the integrated face frame 6 form a rigid connection, which improves the vibration resistance of the lamp structure and avoids loosening or displacement of parts due to external force collisions. The upper frame 81 and lower frame 82 are rectangular rings, separate and symmetrical. The upper frame 81 is provided with a fastening buckle 10 and a mating column 9, and the lower frame 82 has a mounting groove 14 and a mating hole 13. The two work together to position, lock and strengthen the seal.

[0048] Reference Figures 1-3 The upper frame 81 is provided with a fastening buckle 10 facing the lower frame 82. The lower frame 82 is provided with a mounting groove 14 with a through hole. When the upper frame 81 and the lower frame 82 are assembled, the fastening buckle 10 passes through the through hole of the mounting groove 14 to lock the upper frame 81 and the lower frame 82.

[0049] Specifically, when the buckle 10 is fully embedded in the mounting groove 14, the upper frame 81 and the lower frame 82 simultaneously compress the sealing strip 11 between them, causing it to elastically deform and fill the gap, ensuring that the lamp meets the dustproof and waterproof requirements of IP44 protection level.

[0050] Reference Figures 3-5 An integrated faceplate 6 protrudes from the inner side to form a mounting plate 12. The upper frame 81 and the lower frame 82 are respectively connected to the mounting plate 12. The mounting plate 12 has mounting holes 15 through its upper and lower surfaces. The sensor body 72 passes through the mounting holes 15 and is detachably mounted on the mounting plate 12.

[0051] Specifically, the mounting plate 12, as a protruding structure inside the integrated face frame 6, provides a mounting and positioning surface for the upper frame 81 and the lower frame 82. The mounting holes 15 are located in the non-light-emitting area at the edge of the integrated face frame 6 to avoid blocking light or creating shadows.

[0052] Working principle: When the sensor body 72 detects human movement, it generates an electrical signal through the built-in infrared or microwave sensing module. This signal is transmitted to the driving power supply 71 of the driving component 7 via a wire. The driving power supply 71 controls the power supply or dimming output of the LED light panel 2 according to the signal command: when a human body is detected approaching, the driving power supply 71 turns on the power to the LED light panel 2, causing it to light up; when the human body leaves the sensing range and a preset delay is reached, the driving power supply 71 cuts off the power supply, achieving an energy-saving effect.

[0053] The upper frame 81 and lower frame 82 of the plastic frame 8 are clamped and fixed to the integrated face frame 6 by the insertion of the mating column 9 and the mating hole 13, and the locking of the buckle 10 and the mounting groove 14, forming a rigid support structure to avoid light refraction distortion. The double sealing of the sealing strip 2 11 and sealing strip 1 5 enables the lamp to achieve an IP44 dustproof and waterproof rating, which is suitable for humid or dusty environments. When the sensor body 72 needs to be replaced, there is no need to disassemble the internal structure of the lamp. Just separate the upper frame 81 and the lower frame 82, and the old sensor can be directly removed from the mounting hole 15 of the mounting plate 12 and the new component can be installed. This greatly simplifies the maintenance process and reduces the technical threshold and maintenance cost.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
