[0029] Please refer to Figure 1 - Figure 9 This embodiment provides a wireless charging device for emergency lighting fixtures, including: The lamp body has a first connecting part 110, a second connecting part 120, and a main lamp 130 disposed between the first connecting part 110 and the second connecting part 120 at both ends. A drive power module 2 is installed on the first connecting part 110; the drive power module 2 is electrically connected to the main lamp 130; The drive power module 2 is used to receive mains power, convert the mains power into a suitable voltage and current, and control the main lamp 130 light source to turn on or off.

[0030] A wireless power supply coil 3 is installed in the second connection part 120; the wireless power supply coil 3 is electrically connected to the main light 130 or to the drive power module 2 through a conductive cable 4; An emergency light module 5 is detachably connected to the second connecting part 120. A receiving coil 6 is provided on one side wall of the emergency light module 5 corresponding to the position of the wireless power supply coil 3. The emergency light module 5 includes an emergency light 510, an emergency module circuit board 520, and a rechargeable battery 530. The receiving coil 6, the emergency light 510, the rechargeable battery 530 are electrically connected to the emergency module circuit board 520. The emergency light 510 is exposed on the outer end face of the emergency light module 5, and the direction of its light is the same as that of the main light 130. The emergency module circuit board 520 and the rechargeable battery 530 are stacked on top of the emergency light 510.

[0031] The emergency module circuit board 520 and the rechargeable battery 530 are stacked on top of the emergency light 510. This is not limited to the emergency module circuit board 520 being located on top of the emergency light 510 and the rechargeable battery 530 being located on top of the emergency module circuit board 520; the rechargeable battery 530 may also be located between the emergency module circuit board 520 and the emergency light 510.

[0032] The main light 130 includes a lampshade 131, a light source board 132, and a lamp housing 133. The conductive cable 4 is routed along the back of the lamp housing 133 to connect to the wireless power supply coil 3. The lamp housing 133 itself can also be a profile that provides heat dissipation for the light source board 132.

[0033] By designing the emergency light module 5 to be detachably connected to the second connection part 120, and the rechargeable battery 530 not using a traditional wired connection to drive the power module 2, the rechargeable battery 530 is directly detachably connected to the second connection part 120 along with the emergency light module 5, and receives power from the wireless power supply coil 3 by relying on the receiving coil 6 in the emergency light module 5.

[0034] The rechargeable battery 530 and the emergency module circuit board 520 can be connected via terminals or battery holders.

[0035] The rechargeable battery 530 has a limited lifespan. As the years go by, the lifespan of the rechargeable battery 530 decreases, requiring replacement. When replacing the rechargeable battery 530, maintenance personnel simply need to use a ladder to disconnect the emergency light module 5 directly from the second connection part 120. Since there are no connecting wires interfering, the emergency light module 5 separates directly from the light fixture body. This allows maintenance personnel to stand stably on the ladder in a suitable posture, remove the rechargeable battery 530 from the emergency light module 5, replace it with a new one, and then reinstall the emergency light module 5 into the second connection part 120. The receiving coil 6 then receives power from the wireless power supply coil 3. This increases the safety and convenience of battery replacement for maintenance personnel, improving efficiency.

[0036] This avoids the traditional rechargeable battery installation structure, which requires maintenance personnel to tilt their heads back and reach out to remove the battery from the light fixture and install the new battery during the entire replacement process. This is difficult for maintenance personnel who are standing on a ladder, as it is strenuous, unstable, and makes the operation challenging.

[0037] Please refer to Figure 1 and Figure 3 Both the drive power module 2 and the emergency light module 5 include a support housing A, and the outer contour of the support housing A of the two is the same.
