Description

Technical Field

[0001] The present invention relates to the technical field of downlight devices, and in particular to a cultural and creative downlight based on the Internet of Things and a control method thereof. Background Art

[0002] As a common lighting fixture, downlights are widely used in the field of indoor lighting decoration. They have the characteristics of small size, beautiful shape, concentrated light, etc. They can provide uniform and soft lighting effects for specific areas. They are widely used in homes, commercial places and office environments.

[0003] Traditional downlights have many defects in practical applications. In terms of IoT functions, traditional downlights usually only have simple circuit control and cannot achieve connection and interaction with external smart devices or networks. It is difficult to meet the functional requirements of modern smart home and smart building management systems for remote control of lamps, scene linkage, etc.

[0004] In terms of energy saving and dimming, most traditional downlights use fixed power and single color temperature light sources, and cannot automatically adjust the brightness and color temperature according to the ambient light intensity and actual use needs. In areas with sufficient natural light or less human activity, it is impossible to reduce the power to save electricity, resulting in energy waste; and in different scenarios, such as reading, leisure, work, etc., it is impossible to provide a suitable lighting atmosphere and lacks the flexibility of dimming function.

[0005] In terms of the flexibility of downlights during installation, traditional downlights generally adopt a fixed installation structure, and the angle is difficult to adjust after installation. They are less adaptable in some scenes that require special lighting angles or frequently change lighting directions. For example, in commercial display areas, when the display layout is adjusted or the key lighting area changes, it is difficult for traditional downlights to quickly change the lighting direction, affecting the lighting effect and convenience of use. Summary of the invention

[0006] 1. Technical issues

[0007] The present invention aims to overcome the defects of traditional downlights in terms of lack of Internet of Things functions, insufficient energy-saving and light-changing capabilities, and poor installation flexibility, and to provide a cultural and creative downlight based on the Internet of Things.

[0010] Furthermore, the lighting assembly includes an LED lamp bead board installed at the lower end of the interior of the downlight housing, on which a plurality of LED lamp beads with different color temperatures are evenly distributed, and also includes a diffusing lens arranged below the LED lamp bead board.

[0011] Furthermore, the Internet of Things control module includes a control circuit board fixedly arranged inside the downlight housing, and the control circuit board is integrated with a microprocessor and a Zigbee communication chip for realizing the communication connection between the downlight and an external intelligent gateway; the microprocessor is electrically connected to the LED lamp bead board and the sensor module.

[0013] Furthermore, the mounting base includes a shell and a rotating socket rotatably arranged on the lower end surface of the shell, the downlight housing is rotatably arranged on the lower end surface of the rotating socket through a damping shaft, an elastic buckle is fixedly arranged on the side surface of the shell, a conductive slip ring is fixedly arranged on the upper end surface of the shell, a through hole for the cable to pass through is arranged in the center of the mounting base, and a wiring terminal is fixedly arranged on the upper end surface of the downlight housing.

[0014] Another aspect of the present invention provides a control method for a cultural and creative downlight based on the Internet of Things, and the steps are as follows:

[0015] S1, the ambient light sensor monitors the ambient light intensity in real time and transmits the data to the microprocessor in the IoT control module; the human body sensing sensor monitors the human body activities in real time and transmits the data to the microprocessor;

[0016] S2, when the ambient light intensity is lower than the preset threshold and the human body sensing sensor 4 detects human activity, the microprocessor controls the LED lamp bead board in the lighting assembly to turn on, and the LED lamp beads of the corresponding color temperature are lit according to the preset lighting mode, and the light is evenly emitted through the diffuser lens;

[0017] S3, the microprocessor receives control instructions transmitted by the external intelligent gateway through the Zigbee communication chip, such as adjusting the light brightness, switching the light color temperature or timing the light switch operation, and controls the LED lamp bead board according to the instructions;

[0018] S4. When the ambient light intensity is higher than a preset threshold or the human body sensing sensor does not detect human activity within a preset time, the microprocessor controls the lighting component to turn off.

[0019] (III) Technical Effect

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] 1. Intelligent Internet of Things function: With the help of the Zigbee communication chip in the Internet of Things control module, the cultural and creative downlight of the present invention can establish a stable communication connection with the external intelligent gateway, thereby realizing remote control. Users can conveniently switch the downlight, adjust the brightness, switch the color temperature, and set the timing through the mobile phone APP or smart home control system, which greatly improves the convenience and intelligence of lighting control and meets the personalized lighting needs in different scenarios.

[0022] 2. Significant energy-saving and light-changing effects: Multiple LED lamp beads with different color temperatures in the lighting components work together with ambient light sensors and human body sensing sensors. When the ambient light intensity is lower than the preset threshold and human activity is detected, the downlight automatically turns on and selects LED lamp beads with appropriate color temperatures according to the preset lighting mode to light up, providing a comfortable lighting environment; when the ambient light becomes stronger or no one is active for a period of time, the downlight automatically turns off. This intelligent sensing and multi-color temperature switching function effectively avoids unnecessary energy consumption, and has a significant energy-saving effect compared to traditional downlights, especially in large commercial places or public buildings, which can significantly reduce lighting electricity costs.

[0023] 3. High installation flexibility: The upper end of the downlight housing is connected to the mounting base through a damping shaft. The rotating base design of the mounting base allows the downlight to be flexibly rotated within a certain range to adjust the lighting angle. During the installation process, whether it is to determine the lighting direction during the initial installation, or to change the downlight angle later due to changes in the space layout or adjustments to the lighting needs, it can be easily achieved without complicated disassembly and reinstallation procedures. The conductive slip ring ensures the stability of power and signal transmission during the rotation of the downlight, greatly improving the adaptability and flexibility of the downlight in different installation scenarios.

[0035] A sensor module is also provided on the outside of the downlight housing 1, and the sensor module includes an ambient light sensor 3 and a human body sensing sensor 4. The ambient light sensor 3 is fixedly arranged at the lower end of the downlight housing 1, and the human body sensing sensor 4 is fixedly arranged at the side of the downlight housing 1. The sensor module is electrically connected to the Internet of Things control module, and a mounting base 6 is provided at the upper end of the downlight housing 1 for rotational connection via a damping shaft 5.

[0036] The mounting base 6 includes a shell 61 and a rotating holder 62 rotatably arranged on the lower end surface of the shell 61. The downlight housing 1 is rotatably arranged on the lower end surface of the rotating holder 62 through a damping shaft 5. An elastic buckle 63 is fixedly arranged on the side of the shell 61. A conductive slip ring 10 is fixedly arranged on the upper end surface of the shell 61. A through hole 11 for the cable to pass through is arranged in the center of the mounting base 6. A wiring terminal 12 is fixedly arranged on the upper end surface of the downlight housing 1.

[0037] Another aspect of the present invention provides a control method for a cultural and creative downlight based on the Internet of Things, and the steps are as follows:

[0038] S1, the ambient light sensor 3 monitors the ambient light intensity in real time and transmits the data to the microprocessor in the Internet of Things control module; the human body sensing sensor 4 monitors the human body activities in real time and transmits the data to the microprocessor;

[0039] S2, when the ambient light intensity is lower than the preset threshold and the human body sensing sensor 4 detects human activity, the microprocessor controls the LED lamp bead board 21 in the lighting assembly 2 to turn on, and the LED lamp beads of the corresponding color temperature are lit according to the preset lighting mode, and the light is evenly emitted through the diffuser lens 22;

[0040] S3, the microprocessor receives control instructions transmitted by the external intelligent gateway through the Zigbee communication chip 8, such as adjusting the light brightness, switching the light color temperature or timing the light switch operation, and controls the LED lamp bead board 21 according to the instructions;

[0041] S4. When the ambient light intensity is higher than a preset threshold or the human body sensing sensor 4 does not detect human activity within a preset time, the microprocessor controls the lighting component 2 to turn off. If the AC-DC power conversion circuit in the power module is powered off at this time, the built-in detection circuit automatically switches to the lithium battery 9 for power supply to maintain the low-power operation state of the Internet of Things control module and the sensor module, and waits for the next trigger condition to be met to start the lighting component 2 again.

[0042] The working principle of a cultural and creative downlight based on the Internet of Things of the present invention is as follows: the downlight shell 1 serves as an overall protection and support structure, and the reflective coating on its inner wall can effectively reflect the light emitted by the lighting component 2, enhancing the lighting effect, and the cultural and creative pattern engraving layer on the surface of the shell gives it cultural and artistic characteristics. The LED lamp bead board 21 in the lighting component 2 is the light-emitting core, and LED lamp beads of different color temperatures can provide a variety of lighting effects under different scene requirements, and the astigmatism lens 22 makes the light evenly scattered. The sensor module includes an ambient light sensor 3 and a human body sensing sensor 4 (human body infrared pyroelectric sensor), which are respectively used to monitor the ambient light intensity and human body activity, and transmit the data to the Internet of Things control module. The microprocessor integrated in the control circuit board 7 in the Internet of Things control module receives and processes the sensor data, and communicates with the external intelligent gateway through the Zigbee communication chip 8 to realize the reception and execution of remote control instructions, thereby controlling the working state of the lighting component 2. The AC-DC power conversion circuit of the power module supplies power to the entire downlight when the mains power is normal. When the mains power is off, the detection circuit automatically switches to the lithium battery 9 for power supply, ensuring low power consumption of key components such as the IoT control module and the sensor module. The mounting base 6 is connected to the downlight housing 1 through the damping shaft 5 to achieve flexible adjustment of the downlight lighting angle. The conductive slip ring 10 ensures power and signal transmission during the rotation process, and the elastic buckle 63 facilitates installation and fixation.

[0043] The working process of the cultural and creative downlight based on the Internet of Things of the present invention is as follows:

[0044] 1. Equipment initialization and startup: After the downlight is powered on, the AC-DC power conversion circuit in the power module starts to work, converting the mains power into a suitable DC voltage to power the entire downlight. At this time, the microprocessor of the IoT control module is initialized, and each sensor module is started at the same time. The ambient light sensor 3 starts to monitor the ambient light intensity, and the human body sensor 4 starts to monitor the surrounding human activities.

[0045] 2. Data collection and transmission: The ambient light sensor 3 collects ambient light intensity data in real time and transmits the data to the microprocessor in the IoT control module. The human body sensing sensor 4 monitors human activities in real time and immediately transmits the signal to the microprocessor once human activities are detected.

[0046] 3. Lighting judgment and control: The microprocessor makes a judgment after receiving the data from the ambient light sensor 3 and the human body sensing sensor 4. When the ambient light intensity is lower than the preset threshold and the human body sensing sensor 4 detects human activity, the microprocessor sends an on command to the LED lamp bead board 21 in the lighting component 2, and the LED lamp beads of the corresponding color temperature are lit according to the preset lighting mode, and the light is evenly emitted through the diffuser lens 22 to provide a suitable lighting environment.

[0047] 4. Internet of Things communication and remote control: During the operation of the downlight, the microprocessor continuously communicates with the external intelligent gateway through the Zigbee communication chip 8. When receiving control instructions transmitted by the external intelligent gateway, such as adjusting the light brightness, switching the light color temperature, or timing the light on and off, the microprocessor controls the LED lamp bead board 21 accordingly according to the instructions, realizes remote intelligent control, and is set as the first priority through the control of the external intelligent gateway.

[0048] 5. Energy saving and automatic shutdown: When the ambient light intensity is higher than the preset threshold or the human body sensor 4 does not detect human activity within the preset time, the microprocessor sends a shutdown command to the lighting component 2, and the LED lamp bead board 21 is turned off and stops emitting light to achieve energy saving. If the AC-DC power conversion circuit in the power module is powered off at this time, the built-in detection circuit of the power module automatically switches to the lithium battery 9 for power supply, maintains the low-power operation state of the Internet of Things control module and the sensor module, and waits for the next trigger condition to be met to start the lighting component 2 again.

[0049] 6. Installation and adjustment: During the installation process, the mounting base 6 is fixed to a predetermined position, such as a ceiling keel or a wall bracket, through the elastic buckle 63 on the side of its shell 61. The downlight housing 1 is connected to the rotating clamp 62 of the mounting base 6 through the damping shaft 5. The angle of the downlight housing 1 can be manually adjusted according to actual lighting needs. During the adjustment process, the conductive slip ring 10 on the upper end face of the mounting base 6 ensures the stable transmission of power and signals, so that the downlight can work normally at different angles. The through hole 11 in the center of the mounting base 6 is convenient for the cable to pass through and wire, and the wiring terminal 12 on the upper end face of the downlight housing 1 realizes the connection with the power supply and signal lines.

[0050] It should be noted that the microprocessor, Zigbee communication chip, external intelligent gateway, AC-DC power conversion circuit, and detection circuit in this embodiment are all existing mature technologies and are widely used, so they will not be described in detail in this solution.

[0051] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
