[0027] Figure 1 This is a schematic diagram of the exploded structure of the wireless charging lamp provided by the utility model; Figure 2a-2c This is a schematic diagram of the assembly structure of the wireless charging lamp provided by the utility model, one of which is shown in FIG. Figure 1-2c As shown, the present invention provides a wireless charging lamp, which can be a lamp suitable for any scene. The present invention is explained by taking a stage lamp as an example. The wireless charging lamp includes a lamp body, in which a wireless coil 8, a wireless charging control system 6, a battery pack control system 5 and a main control system (not shown in the figure) are provided. The wireless charging control system 6 is electrically connected to the wireless coil 8, the battery pack control system 5 and the main control system respectively. The wireless coil 8 and the wireless charging control system 6 are used to cooperate to realize wireless charging. The wireless charging control system 6 can charge the battery pack control system 5. When the wireless charging control system 6 fails and cannot power the lamp, it sends a signal to the main control system, and the main control system sends a signal to the battery pack control system 5. The battery pack control system 5 supplies power to the lamp to ensure the normal operation of the stage lamp. At the same time, the wireless charging stops working to avoid problems such as component damage caused by abnormal operation.

[0028] Optionally, the wireless charging control system 6 includes a circuit board, and the wireless coil 8 can be fixed on the circuit board of the wireless charging control system 6 through an EVA gasket 7 .

[0029] Optionally, the lamp body includes a front cover 1, a heat sink 4, and a rear cover 9. The front cover 1 is located at the front end of the heat sink 4, and the rear cover 9 is located at the rear end of the heat sink 4. The front cover 1, the heat sink 4, and the rear cover 9 form a cavity that accommodates the wireless coil 8, the wireless charging control system 6, the battery pack control system 5, and the main control system. The front cover 1, the heat sink 4, and the rear cover 9 can be connected by screws or snaps, and will not be further described.

[0030] Figure 3 This is a circuit diagram of the wireless charging control system provided by the utility model. Figure 3 As shown, optionally, the wireless charging control system 6 includes a wireless charging control chip U1. In this embodiment, the model of the wireless charging control chip U1 is STWL98. The input end of the wireless charging control chip is provided with a resonant circuit and a protection circuit. The resonant circuit is composed of a capacitor, and the protection circuit is composed of transient voltage suppression diodes TVS1 and TVS1. The wireless coil 8 is electrically connected to the resonant circuit and the protection circuit respectively. The wireless coil 8 is represented by L1. The output voltage of the wireless charging control system 6 is VOUT. The output end of the wireless charging control chip is electrically connected to the main control system through a preset communication interface. Specifically, it can be connected to the main control system through an I2C communication interface SDA / SCL.

[0031] The wireless charging control system 6 and the wireless coil 8 implement wireless charging and can also monitor the wireless charging status. The wireless coil 8 uses electromagnetic induction to induce electrical energy from a magnetic field. This energy is then converted by the wireless charging control chip U1 into the voltage required by the back-end load and output through the VOUT port. If the charging status of the wireless coil 8 is abnormal, U1 detects the abnormality and shuts down its internal logic circuitry, preventing the VOUT port from outputting voltage. Simultaneously, it notifies the MCU in the main control system via the I2C communication ports SDA / SCL, which in turn controls the battery pack control system 5 to provide power. U1 then resets and troubleshoots the issue. Once the problem is resolved, the main control system disconnects the battery power supply, re-enables the internal logic circuitry, and resumes supplying power to the back-end load through the VOUT port. This utility model significantly improves the safety of wireless charging within the lamp through the coordinated operation of the wireless charging control system 6 and the battery pack control system 5, preventing component damage and other issues caused by improper wireless charging. It also ensures lamp operation stability, ensuring that self-test errors do not affect lamp operation and that any issues can be quickly resolved.

[0032] Figure 4 This is a schematic diagram of the structure of the wireless coil 8 provided by the present invention. Figure 4 As shown, optionally, the size and inductance of the wireless coil 8 are determined based on the use environment and use conditions of the lamp. The size and inductance of the coil can be adjusted according to different use environments and use conditions. The energy conversion rate can be adjusted to the most appropriate state to avoid energy waste. The specific adjustment plan can be determined through multiple tests. The present invention does not limit this and will not elaborate on it.

[0033] Figure 5 This is a circuit diagram of the battery pack control system 5 provided by the present invention, as shown in FIG. Figure 5As shown, optionally, the battery pack control system 5 includes a battery pack, a switching tube and a triode, the base of the triode is electrically connected to the main control system, the collector of the triode is connected to the gate of the switching tube, and the source and drain of the switching tube are respectively connected to the battery pack.

[0034] The battery control system 5 serves as a backup energy source. The battery control system 5 is installed inside the lamp. When the wireless charging function is turned off or an abnormality occurs, the battery control system 5 starts the battery pack to supply power, thereby ensuring the normal use of the lamp.

[0035] When the wireless charging control system 6 is shut down or malfunctioning, the EN1 signal connecting the battery pack control system 5 to the active system goes high, pulling the G pole of transistor Q2 high and conducting the S and D poles. The conduction of the S and D poles of the transistor pulls the G pole of the switch Q1 low, conducting the S and D poles, and turning on the battery pack to supply power to the back-end load. When the wireless charging control system 6 is operating normally, EN1 goes low, pulling the G pole of transistor Q2 low and disconnecting the S and D poles. The disconnection of the S and D poles of the transistor pulls the G pole of the switch Q1 high, disconnecting the S and D poles, and shutting down the battery pack.

[0036] Optionally, the lamp body also includes a lighting control system 3 and an optical lens 2 located at the front end of the lighting control system 3. The lighting control system 3 includes several light sources and corresponding driver circuits. Optionally, the parameters of the light sources are determined based on the lamp's operating environment and conditions. The lighting control system 3 can be modified to suit different lamp design requirements, thereby achieving different lighting effects and effects. Both the lighting control system 3 and the wireless coil 8 can be customized as needed. By adjusting appropriate parameters according to different usage scenarios, the overall system's energy conversion efficiency can be improved to avoid waste.

[0037] The present invention also provides a lighting system comprising at least one wireless transmission system and a plurality of wireless charging lamps. The wireless transmission system transmits energy to wireless coils in the wireless charging lamps. Optionally, the protocol of the wireless transmission system is consistent with the protocol of the wireless charging lamps. The wireless transmission system includes a wireless transmission coil, which generates a magnetic field through alternating current. The wireless coils in the wireless charging lamps induce electrical energy from the magnetic field through the principle of electromagnetic induction.

[0038] In summary, the wireless charging lamp and lamp system provided by the present invention have the following advantages:

[0039] 1. With wireless charging power supply, no cables and connectors are used for power supply, and the lamps can be moved or replaced at will, which greatly improves work efficiency.

[0040] 2. One-to-many charging is possible, and only one wireless transmission system is needed to power and charge all lamps within the coverage area.

[0041] 3. Different wireless transmission systems can have different protocols, automatically identifying lamps with the same protocol from all lamps and powering them, realizing intelligent power supply.

[0042] 4. Solve the safety hazards such as leakage of cables and connectors.
