[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] like Figure 1-5 As shown, the present invention provides a rechargeable magnetic ceiling light for vehicles and its control system, including a lamp housing 1, a light-transmitting lamp cover 2 fixedly connected to the bottom of the lamp housing 1, a lamp holder 5 fixedly connected to the top of the inner cavity of the lamp housing 1, a lamp plate 6 fixedly connected to the bottom of the lamp holder 5, a charging coil 52, a COB chip 54 and a PWM dimming module 55 provided inside the lamp holder 5, and a magnetic block 4 fixedly connected to the top center of the lamp housing 1, and the lamp housing 1 is attracted and fixed to the bottom of the ceiling 7 by the magnetic block 4; The top of the inner cavity of the lamp holder 5 is fixedly connected to the mounting ring 51, and the charging coil 52 is fixedly installed inside the mounting ring 51. A wireless charging module 8 is fixedly installed on the top of the canopy 7, and the wireless charging module 8 is matched with the charging coil 52. The PWM dimming module 55 supports three levels of brightness adjustment, with low illuminance at 50-100 lux, medium illuminance at 200-300 lux, and high illuminance at 800-1000 lux. A switch button 3 is installed on one outer wall of the lamp housing 1; This application takes into account that traditional car roof lights mostly use professional wiring for fixed installation, which cannot support user self-disassembly and assembly. This defect makes it difficult for users to flexibly disassemble the roof light according to actual usage scenarios, and thus cannot move it to different areas for extended use, such as as a reading light in the car or as a camping light outdoors, which seriously limits the product's applicability and user experience. To this end, this application sets a magnetic block 4 structure on the top of the lamp housing 1. The magnetic block 4 structure is attached and fixed to the iron structure on the ceiling 7, realizing quick installation and disassembly of the magnetic ceiling light. It is convenient for users to remove the magnetic ceiling light and use it as a reading light or camping light according to actual usage needs. In addition, the brightness can be adjusted by controlling the pressing time of the switch button 3, which can effectively cope with different usage scenarios. The magnetic ceiling light can be charged by the wireless charging module 8 in conjunction with the charging coil 52 in the lamp holder 5. After it is fully charged, the wireless charging power supply module can be turned off by controlling the mobile APP. It should be noted that the magnetic block 4 on the top of the lamp housing 1 is made of a high magnetic material, such as neodymium iron boron magnet, while the part on the roof 7 corresponding to the magnetic block 4 is made of iron material, which makes it easy for the magnetic block 4 to be directly attached to the roof 7. After the magnetic block 4 is attached and fixed to the roof 7, the charging coil 52 in the lamp holder 5 can be precisely aligned with the wireless charging module 8, improving the charging efficiency. In addition, the power conversion efficiency of the wireless charging module 8 is ≥90%, supports 15-minute short-term fast charging, the luminous efficacy of the COB chip 54 is ≥120lm / W, the heat dissipation substrate 53 can keep the LED junction temperature ≤85℃, and linear brightness adjustment can be achieved through the PWM dimming module 55.

[0023] like Figure 6 As shown, a control system for a rechargeable magnetic ceiling light includes: Switch button 3 is used to send control commands; The large-screen host is communicatively connected to the switch button 3, and is used to receive instructions from the switch button 3 and activate it; The domain controller is communicatively connected to the large screen host and is used to perform light switching and brightness adjustment operations; The TBOX is connected in communication with the large screen host and is used to perform display and operation of light switching, brightness adjustment, and wireless charging switch control. The power module provides 12V voltage and GND ground to power the large screen host, domain controller, TBOX and wireless charging module 8. The light-emitting module, which is communicatively connected to the TBOX, is used for emitting light and providing illumination; The wireless charging module 8 is powered by a 12V power supply and is communicatively connected to the TBOX. The logic for brightness adjustment is as follows: Press switch button 3 to turn on the light at the low setting; Press and hold the switch button for 33 seconds to increase the light brightness to medium level. Press and hold the switch button for 35 seconds to increase the light brightness to the highest level. When in operation, when the user presses the switch button 3 on the side wall of the lamp housing 1, the switch button 3 sends the command "low-level on" to the large screen host. After receiving the command, the large screen host then synchronously distributes it to the domain controller. The domain controller drives the PWM dimming module 55 in the lamp holder 5 to output the drive current corresponding to the low-level brightness of 50-100 lux, and the COB chip 54 is charged to achieve low-level lighting. During this process, the large screen host also sends the "low-level on" status to the TBOX, and the TBOX displays "Interior dome light - low-level on" on its interface. When the user presses and holds the switch button for 33 seconds while the lights are on at low brightness, the switch button sends a "brightness increased to medium" command to the large screen host. After the large screen host parses the command, it sends a "medium brightness" execution signal to the domain controller. The domain controller controls the PWM dimming module to adjust the duty cycle and outputs the drive current corresponding to the 200-300 lux medium brightness, thus increasing the light brightness. The TBOX simultaneously updates the status display to "interior dome light - medium brightness on". When the user presses and holds the switch button for 35 seconds while the light is on at the medium setting, the switch button sends a "brightness increased to high" command to the large screen host. The large screen host then distributes the command to the domain controller. The domain controller adjusts the duty cycle of the PWM dimming module and outputs the drive current corresponding to the high brightness of 800-1000 lux. The TBOX status is updated to "Interior dome light - high brightness on". When the user manually clicks "Wireless Charging On" through the TBOX interface, TBOX sends a "Wireless Charging On" signal to the wireless charging module 8. The wireless charging module 8 is powered on and establishes electromagnetic induction with the charging coil 52 in the lamp holder 5 to start charging. When the battery is fully charged, TBOX automatically sends a "Charging Stop" command to turn off the power of the wireless charging module 8 to avoid overcharging. When the user presses switch button 3 again, switch button 3 sends a "lights off" command. The large screen host drives the domain controller to cut off the current of the PWM dimming module, the lights go out, and the TBOX updates its status to "top light off".

[0024] Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
