[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 One embodiment provided by this utility model:

[0027] A lighting device with dual-power supply and fast switching includes a controller 5, a constant current power supply 4, a bracket 9, a battery 6, a charging power supply 3, and an LED module 7. The charging power supply 3 and the constant current power supply 4 are both AC-DC power supplies. The charging power supply 3 and the constant current power supply 4 are respectively fixed on both sides of the battery 6. The controller 5 is fixed to the side of the battery 6 by bolts.

[0028] The constant current power supply 4 is connected to the controller 5 via a circuit, the charging power supply 3 is connected to the controller 5 via a circuit, and the controller 5 is connected to the LED module 7 and the battery 6 via a circuit. The constant current power supply 4 supplies power to the LED module 7 through the controller 5, and the charging power supply 3 supplies power to the battery 6 through the controller 5. The controller 5 achieves switching between the two power supplies through a high-speed switching circuit, with a switching time of ≤0.03 seconds. The charging mode of the battery 6 is constant current and constant voltage, and the charging cut-off voltage is 1.05-1.1 times the rated voltage. An antenna 8 is connected to one side of the controller 5 via a circuit. A lampshade 2 is fixedly installed on the top of the battery 6 by bolts, and a connector 1 is fixedly installed on the top of the lampshade 2.

[0029] This utility model proposes a lighting device with dual-power supply and rapid switching. Through dual-power collaborative design, millisecond-level switching technology, and remote intelligent control, it achieves efficient, stable, and long-life lighting power supply. Specifically, the dual-power switching time of the lighting device is in the millisecond range, and the lighting interruption time is imperceptible, meeting the requirements for safe lighting and enabling seamless lighting. The overall system efficiency is >90%, the constant current drive efficiency is ≥94%, the charging power efficiency is ≥93%, and the battery charging adopts a "constant current and constant voltage" mode with a charging efficiency >94%, making the overall system more efficient and energy-saving. The use of a boost circuit extends its lifespan to over 50,000 hours. Through constant voltage charging to prevent overcharging and BMS protection to prevent over-discharge, the battery cycle life is increased by 30%-40%, effectively improving the overall service life of the device. Furthermore, the modular design facilitates assembly and maintenance, and damage to the charging power supply does not affect the LED constant current drive, ensuring lighting and enhancing reliability.

[0030] More specifically, in this application, the constant current power supply 4 directly provides a stable current to the LED module 7, avoiding damage to the LED chip from current fluctuations and improving lighting efficiency. The charging power supply 3 charges the battery 6 and switches to power the LED module 7 when the main power supply is abnormal. The output voltage matches the rated voltage of the LED. The controller 5 integrates a voltage / current detection unit to monitor the power supply and battery status in real time. When the mains power fails abnormally or the voltage drops by ≥20%, a switching command is triggered. The switching time is ≤0.03 seconds. The switching circuit achieves millisecond-level switching by controlling the dual power supplies through a microcontroller, allowing the constant current power supply 4 and the charging power supply 3 to switch arbitrarily within milliseconds, ensuring lighting safety, system efficiency >92%, and improving product lifespan.

[0031] Working principle: When the device is in use, the constant current power supply 4 directly provides a stable current to the LED module 7 through the controller 5, and the charging power supply 3 charges the battery 6 through the controller 5. When the main power supply is working normally, the charging power supply 3 is responsible for charging the battery 6 to ensure that the battery 6 is fully charged so that it can immediately switch to backup power in case of main power failure. The controller 5 integrates a voltage / current detection unit, which can monitor the status of the main power supply and the battery 6 in real time. When the mains power is abnormal, the controller 5 will immediately trigger a switching command. The controller 5 is connected to an external communication network through the antenna 8 to realize remote intelligent control. Users can dynamically adjust the power supply strategy of the lighting equipment through a mobile application or remote control center, such as adjusting the brightness and setting timer switches.

[0032] When in use, if the mains power is normal, the constant current power supply 4 supplies power to the LED module 7 and the charging power supply 3 charges the battery 6. When the controller 5 detects an abnormality in the mains power, it triggers a switching command. The high-speed switching circuit completes the switching within ≤0.03 seconds. The battery 6 supplies power to the LED module 7 through the controller 5. The battery 6 continuously supplies power to the LED module 7 to ensure uninterrupted lighting. When the mains power returns to normal, the controller 5 triggers the switching command again to return to the initial state. The constant current power supply 4 continues to supply power to the LED module 7 and the charging power supply 3 continues to charge the battery 6.

[0033] In this invention, the principle of dual-path coordination and millisecond-level switching is as follows: the constant current power supply 4 and the charging power supply 3 are independent AC-DC power supplies, located on both sides of the battery 6, forming a dual-path power supply architecture. The controller 5 has a built-in high-speed switching circuit (which can be built using switching elements such as MOSFETs controlled by a microcontroller; those skilled in the art are familiar with the logic of such circuits, such as controlling the MOSFETs to turn on and off through the output level signal of the microcontroller to achieve power path switching), and monitors the power status in real time (using voltage / current detection units, such as voltage comparators and current sensors, to detect parameters such as mains input and battery level). When the mains power is abnormal (power outage, voltage drop ≥20%), a switching command is triggered. Due to the fast response speed of the switching circuit, the power supply switching between the constant current power supply 4 and the charging power supply 3 can be completed within ≤0.03 seconds. By selecting appropriate component parameters (such as high-frequency response MOSFETs and high-speed microcontrollers), this millisecond-level switching function can be achieved.

[0034] High efficiency, energy saving, and long lifespan are guaranteed. The high efficiency principle: the overall system efficiency is >90%, relying on the efficient design of each module. The constant current power supply 4 adopts a high-efficiency circuit topology such as boost converter (those skilled in the art are familiar with the principles and design of boost circuits, achieving efficient voltage conversion and constant current output through the cooperation of inductors, capacitors, and switching transistors), making the constant current drive efficiency ≥94%. The charging power supply 3 uses a circuit design adapted to battery characteristics, combined with the battery 6's "constant current and constant voltage" charging mode (constant current charging in the constant current stage, entering the constant voltage stage when the voltage reaches 1.05-1.1 times the rated voltage; those skilled in the art can achieve this by adjusting the parameters of the charging chip (such as commonly used switching power supply charging chips) and designing feedback circuits), resulting in a charging efficiency >94%. Those skilled in the art can select appropriate chips and optimize circuit layout (such as reducing line losses and proper heat dissipation) based on their experience in power supply efficiency design to achieve the goal of high efficiency and energy saving.

[0035] Long lifespan principle: The boost circuit topology of the constant current power supply 4 prevents damage to the LED module 7 from current fluctuations, extending the LED chip lifespan to over 50,000 hours (those skilled in the art understand the impact of current stability on LED lifespan; constant current drive can suppress light decay and ensure long lifespan); the battery 6 is protected against overcharge by "constant voltage charging to prevent overcharge (using voltage feedback control of the charging circuit, automatically switching to constant voltage mode or stopping charging when the battery voltage reaches the cutoff voltage), active balancing by the BMS, with a balancing current of not less than 60mA, and SOC estimation accuracy controlled within ±3% (the battery management system can be built using a dedicated BMS chip or microcontroller to achieve voltage, current, temperature monitoring and over-discharge protection)," improving cycle life by 30%-40%. Those skilled in the art can select a suitable BMS solution based on battery characteristics and combine it with charging circuit design to achieve the desired long battery lifespan.

[0036] Modularization enhances reliability. The modular principle involves independent modules for the charging power supply (3), constant current power supply (4), battery (6), and controller (5), assembled using conventional mechanical and electrical connections such as bolts and connectors (e.g., controller 5 is bolted to the side of battery 6, and each power module is connected to the controller and LED module 7 via wires and connectors). Technical personnel can assemble each module based on their mechanical assembly experience and the dimensions and connections shown in the attached diagram. If the charging power supply (3) fails, the constant current power supply (4) independently powers the LED module 7 (the two have independent power supply paths in the circuit design, switched by controller 5), ensuring uninterrupted lighting. Technical personnel can quickly identify and replace the faulty module, guaranteeing equipment reliability and maintainability.

[0037] 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.
