Description

Technical Field

[0001] This utility model relates to the field of lighting device technology, and in particular to an intelligent self-testing emergency light. Background Technology

[0002] Emergency lighting fixtures are critical equipment for ensuring public safety, and their reliability relies on periodic simulated power outage tests (usually achieved by pressing physical test buttons on the fixtures). Current mainstream solutions have significant limitations: manual testing requires maintenance personnel to operate the buttons on-site one by one, which is costly, inefficient, and prone to missing detections; while some fixtures with automatic self-test functions can trigger tests at regular intervals, their method of directly cutting off the power supply through internal circuitry cannot realistically simulate the action of pressing physical buttons and external power outage scenarios, making it difficult to detect button malfunctions or external wiring problems; at the same time, existing solutions generally lack efficient and low-power remote monitoring capabilities—relying on wired communication or short-range wireless technologies (such as Wi-Fi and Bluetooth), which cannot meet the networking requirements of wide coverage, strong penetration, and low power consumption for a large number of fixtures in large or complex buildings, resulting in the inability to obtain test status, results, and fixture health information remotely in real time.

[0003] Therefore, there is an urgent need for a smart emergency light solution that can reliably simulate the real physical button pressing test process (to fully verify the power failure switching function) and integrate low-power wide-area Internet of Things (LPWAN) communication capabilities. Utility Model Content

[0004] The main purpose of this invention is to provide an intelligent self-testing emergency light, which aims to solve the problem of low self-testing efficiency of batch emergency lights.

[0005] To achieve the above objectives, this utility model proposes an intelligent self-testing emergency light, the emergency light comprising:

[0006] The lamp body has a spare battery inside and a test button on the outside;

[0007] A pressing component is disposed on the surface of the lamp body. The pressing component includes a light sensor, a driving assembly, and a pressing shaft connected to the output end of the driving assembly.

[0008] The control unit, externally mounted on the surface of the lamp body, includes an MCU controller, a LoRaWAN communication module, and a lithium battery power supply unit. The MCU controller is electrically connected to the LoRaWAN communication module, and both the MCU controller and the LoRaWAN communication module are electrically connected to the lithium battery power supply unit.

[0009] The light sensor is connected to the MCU controller via an I2C interface to detect the brightness of the lamp body; the driving component is driven by the MCU controller, causing the pressing shaft to press the button to verify the discharge performance of the backup battery.

[0010] Preferably, the control component further includes a timing component, which is electrically connected to the MCU controller and is used to trigger the drive component to start at a preset period.

[0011] Preferably, the light sensor includes a patch photoresistor.

[0012] Preferably, the pressing shaft has a silicone pressing head at one end facing the button, and the contact surface of the pressing head matches the shape of the button surface.

[0013] Preferably, the drive component includes a miniature linear motor, the output shaft of which is coaxially connected to the pressing shaft via a coupling, and the motion trajectory of the pressing shaft coincides with the button pressing direction.

[0014] Preferably, the control component includes a control box disposed on the surface of the lamp body, and the MCU controller and LoRaWAN communication module are located inside the control box.

[0015] Preferably, the lamp body includes a light-emitting panel and a control module.

[0035] This utility model proposes an intelligent self-testing emergency light; please refer to it. Figures 1-9 The emergency light includes a light body 1, a pressing component 2, and a control component 3. The light body 1 has a backup battery inside and a test button 13 on the outside. The pressing component 2 is located on the surface of the light body 1 and includes a light sensor, a drive assembly 21, and a pressing shaft 22 connected to the output of the drive assembly 21. The control component 3 is located on the surface of the light body 1 and includes an MCU controller, a LoRaWAN communication module, and a lithium battery power supply unit. The MCU controller is electrically connected to the LoRaWAN communication module, and both the MCU controller and the LoRaWAN communication module are electrically connected to the lithium battery power supply unit. The light sensor is connected to the MCU controller via an I2C interface for detecting the light... The brightness of the lamp body 1 is monitored. The driving component 21 is driven by the MCU controller, which causes the pressing shaft 22 to press the test button 13 to verify the discharge performance of the backup battery. The above design, by setting a pressing component 2 containing the driving component 21 and the pressing shaft 22 on the surface of the lamp body 1, enables the pressing shaft 22 to automatically press the test button 13 of the lamp body 1, completely replacing manual operation and avoiding the risks of high-risk environments. At the same time, with the help of the lithium battery power supply unit and LoRaWAN communication module extending to the outside of the lamp body 1, test data can be transmitted back to the remote platform in real time for a long time. Ultimately, it realizes unattended compliance self-inspection, real-time fault early warning and operation and maintenance cost optimization, and comprehensively improves the reliability and management efficiency of the emergency light system.

[0036] Furthermore, the control component 3 also includes a timing component, which is electrically connected to the MCU controller. The timing component is used to trigger the drive component 21 to start according to a preset cycle. In this embodiment, the preset cycle is 3 hours, that is, the MCU controller is triggered by the timing component every 3 hours. The MCU controller controls the drive component 21 to drive through the PWM signal, so that the pressing shaft 22 automatically presses the test button 13 of the lamp body 1, thereby simulating the manual pressing of the test button 13 of the lamp body 1. During this process, the light sensor collects brightness data and uploads the detection results to the platform synchronously through the LoRaWAN communication module. If the data displayed on the platform meets the brightness standard data, it means that the backup battery in the lamp body 1 is healthy; otherwise, there is a fault.

[0037] In essence, please refer to Figure 1 and Figure 5 During the aforementioned testing process, the power data of the lithium battery power supply unit in the controller will also be synchronously uploaded to the platform through the LoRaWAN communication module, so that the operator can receive an early warning and avoid the controller 3 from suddenly malfunctioning.

[0038] It should be noted that, in this embodiment, the platform refers to an Internet of Things (IoT) platform.

[0039] In this embodiment, the emergency light also includes two self-testing methods: monthly test and annual test.

[0040] Please refer to the monthly report. Figures 3-9 The MCU controller also controls the drive component 21 through the PWM signal, so that the pressing shaft 22 automatically presses the test button 13 of the lamp body 1, thereby simulating the manual pressing of the test button 13 of the lamp body 1. The light sensor collects the brightness data again to determine whether the backup battery power supply is normal.

[0041] During the annual inspection, the MCU controller also controls the drive component 21 via PWM signal, causing the pressing shaft 22 to automatically press the test button 13 of the lamp body 1. It should be noted that this emergency light self-test is a deep test. The drive component 21 drives the pressing shaft 22 to press and hold the test button 13 for a certain period of time. In this embodiment, this time is 90 minutes. The light sensor continuously collects brightness data and uploads it to the platform synchronously through the LoRaWAN communication module. Based on the lamp brightness data, the platform verifies the long-term discharge capability of the backup battery in the lamp body 1 and determines whether it meets the durability standard. Furthermore, after the data is uploaded, the platform analyzes the battery aging trend in conjunction with historical records to assist in maintenance decisions.

[0042] In this embodiment, the light sensor includes a surface-mount photoresistor, which is mainly used to detect the brightness of the lamp body 1 and transmit the brightness data to the corresponding module. In other embodiments, the light sensor also includes a photodiode, etc.

[0043] For further details, please refer to... Figures 2-4 The end of the pressing shaft 22 facing the button is provided with a silicone pressing head 221. The contact surface of the pressing head 221 matches the shape of the button surface. Since the emergency light self-tests many times, the pressing shaft 22 will affect its surface shape due to friction after pressing the test button 13 multiple times. This design can reduce the friction between the top of the pressing shaft 22 and the test button 13 by using the softness of the pressing head 221, so that the pressing shaft 22 can press the test button 13 multiple times.

[0044] Of course, in other embodiments, other anti-wear structures may also be provided at the top of the pressing shaft 22, such as spraying a wear-resistant coating on the top of the pressing shaft 22.

[0045] In this embodiment, the drive component 21 includes a miniature linear motor, whose output shaft is coaxially connected to the pressing shaft 22 via a coupling, and the movement trajectory of the pressing shaft 22 coincides with the button pressing direction, so as to realize the automatic pressing of the test button 13. The above design eliminates the need for manual high-altitude pressing self-testing, greatly reducing safety hazards.

[0046] In other embodiments, the drive assembly 21 includes a miniature lifting cylinder.

[0047] In this embodiment, the control component 3 includes a control box, which is disposed on the surface of the lamp body 1. The MCU controller and LoRaWAN communication module are located inside the control box to avoid structural damage.

[0048] In this embodiment, please refer to Figure 1 The lamp body 1 includes a light-emitting panel 12 and a control module 11. The light-emitting panel 12 is located at the bottom of the control module 11. The pressing member 2 is located on the side of the light-emitting panel 12 and is located below the bottom of the control module 11. The control member 3 is located on the other side of the light-emitting panel 12 and is located below the bottom of the control module 11. The above arrangement also ensures that the control member 3 and the pressing member 2 can operate normally and reduce external damage or dust contamination.

[0049] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
