INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The present invention relates to a luminaire, and more particularly to a solid state lighting fixture. [Prior Art] At present, solid-state light-emitting elements such as light-emitting diodes (Diode, LED) have gradually replaced cold cathode fluorescent lamps due to their high light quality, high luminous efficiency, long life and low energy consumption. Cathode Fluorescent Lamp (CCFL) is widely used as a lighting device for lighting devices, such as traffic lights, car lights, indoor lights, street lights, highway lights, kanban lamps, underwater lights in swimming pools, etc. S. Shur et al., "Solid-State Lighting: Toward Superior Illumination", published in Proceedings of the IEEE, Vol. 93, No. 10 (October 2005). Conventional light-emitting diode lamps are directly connected to a power source through wires. However, most of the LED lamps, such as street lamps, highway lights, kanban lamps, and swimming pool underwater lights, are placed outdoors, often facing a variety of climatic conditions, including cold, heat, moisture, smoke and other pollution. Indoor lighting, such as bathroom lighting, has strict requirements on environmental factors such as water vapor. When the LED lighting needs to be repaired, the electrical connection between the lamp and the line needs to be destroyed. Therefore, the replacement of the lamp requires a large amount of Assembly time, especially for outdoor luminaires, is much higher than the consumable parts of the luminaires. For underwater lights in swimming pools, it is necessary to drain the water before disassembling and installing the luminaires. Therefore, the present invention contemplates the design of a luminaire that is not limited by electrical connections and that facilitates disassembly and assembly of 200928182. SUMMARY OF THE INVENTION In view of this, it is necessary to provide a solid-state lighting fixture that is easy to assemble and disassemble. a solid-state lighting fixture comprising at least a solid-state lighting fixture, the solid-state lighting fixture further comprising a secondary side coil electrically connected to a power supply and a secondary side coil electromagnetically coupled to the primary side coil The at least one solid-state light-emitting element is electrically connected to the output end of the secondary-side coil, and the human-side coil is electromagnetically coupled with the secondary-side coil to form a voltage-changing device for supplying power to the at least one solid-state light-emitting element. ▲ A solid-state lighting fixture includes at least an I-state light-emitting component, the solid-state lighting fixture further includes an AC-DC conversion circuit and a coil, and the coil and the AC-DC conversion circuit and the solid-state light-emitting component form a loop. Electromagnetic induction is generated within the magnetic field to form a current in the loop to supply power to the solid state lighting element. The above-mentioned solid-state lighting fixture realizes power supply to the tamping light-emitting component through electromagnetic coupling between the coils, and there is no direct electrical connection between the power supply source and the solid-state light-emitting component, thereby avoiding disassembly and assembly inconvenience caused by the wire connection. [Embodiment] Hereinafter, embodiments of the present invention will be further described in detail with reference to the accompanying drawings. As shown in Fig. 1, the solid state lighting fixture comprises two parts, a fixed part 10 and a device part 20. The fixing portion 10 is connected to the power supply V, and includes a switching circuit 12, an oscillating circuit 14 and a secondary coil 16. The power supply v is an AC power supply, and may be 110V or 220V, but is not limited thereto. Switch 200928182: The circuit 12 is connected to the power supply Vji, and the switching circuit i2 can control the conduction and disconnection of the solid state lighting fixture and the power source v. The oscillating circuit 14 is connected between the switching circuit 12 and the secondary side coil 16. Since the power supply v is affected by the power supply voltage fluctuation, the circuit parameter change, the ambient temperature change, etc., the amplitude of the output is unstable, and the supply is enhanced by the oscillating circuit 14. The amplitude and the solution characteristic of the voltage of the primary side coil 16 are the alternating currents of which the voltage input to the secondary side coil 16 through the oscillation circuit 14 is an amplitude 敎. According to the Maxwell's electromagnetic field theory: a varying electric field generates a magnetic field, and when the secondary side coil 16 passes a stable alternating current, a stable alternating magnetic field is generated in the secondary side line 16. " The device unit 2 includes a solid state light emitting element 22, an AC/DC converting power, and a human side coil 26. In this embodiment, the solid-state light-emitting device is a light-emitting diode (LED), but is not limited to the light-emitting diode. It is obvious that the number of the first-pole body 22 can be changed according to the application of the lamp. The plurality of light-emitting diodes 22 form different types of light-emitting diode arrays, and the light-emitting C-electrode body can also realize various flashing operations through a control circuit. The secondary side coil 26 is disposed corresponding to the primary side coil I, and the first side coil 16 is electrically connected to the primary side coil 16 coil. According to Faraday's law,

The frequencies of the currents formed in the coil 16 are the same. The AC/DC converting circuit 24 is connected between the secondary side coil 26 and the light emitting diode 22, and converts the alternating motor generated by the secondary side coil 26 into a direct current ', thereby causing the light emitting diode 22 to emit light for illumination. The type of the parent DC conversion circuit 24 can be appropriately selected as needed, and is adaptively adjusted to a specific voltage value such as 5V, 12v, etc. while converting the alternating current of the secondary side coil 26 into direct current. Of course, the voltage adjustment can also be directly completed by the transformer, and the turns ratio of the two coils 16 and 26 is equal to the voltage ratio of the two coils 16 and 26, so that the number of turns of the two coils 16 and % can be directly adjusted to the secondary side coil. A low-voltage alternating current is formed in 26, and then converted into a direct current to the light-emitting diode 22. As described above, the solid-state lighting fixture of the present invention passes the electromagnetic between the coils
