Description

Technical Field

[0001] This utility model relates to the technical field of lighting and ventilation equipment, and in particular to a fan light. Background Technology

[0002] Currently, most traditional fan lights are only compatible with a single voltage (such as 110V or 220V), while the voltage of power grids varies greatly across the world (e.g., 100V in Japan, 230V in Europe), causing the equipment to malfunction in areas with voltage fluctuations or non-standard voltages. This can lead to excessively high input voltage, making circuit components prone to burnout due to overload, especially in humid environments or frequently touched scenarios; and it also results in wasted energy. Furthermore, traditional fan lights are often poorly designed in terms of structure, making installation and maintenance inconvenient. Utility Model Content

[0024] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0025] Reference Figures 1 to 5 A fan light includes a lamp holder 1, a drive motor 2 mounted on the lamp holder 1, fan blades 3 mounted on the drive motor 2, and a light-emitting part 4 mounted on the lamp holder 1. The top of the lamp holder 1 has a first cavity 11, within which a transformer 5 is installed. The transformer 5 converts an input voltage of 90V-300V into an output voltage of 12V-100V to power the light-emitting part 4 and the drive motor 2, which are driven by alternating current. This allows the fan light to be used with different voltages, ensuring the normal operation of the light-emitting part 4 and the drive motor 2.

[0026] In this scheme, the transformer 5 is connected to a circuit protection module for protecting the circuit. The circuit protection module includes a self-resetting fuse (overcurrent protection), a transient voltage suppression diode (overvoltage protection), and a fuse (short circuit protection), thereby forming a multi-level protection mechanism to improve safety and reliability.

[0027] In one embodiment of this solution, when the input voltage is lower than the output voltage (e.g., the input is 90V and the output needs to be 100V), the transformer 5 is a step-up transformer, which is suitable for low-voltage areas, expands the product's applicability, and avoids the problem of equipment failure to start due to insufficient voltage.

[0028] In another embodiment of this solution, when the input voltage is higher than the output voltage (e.g., if the input is 220V, the output needs to be 24V), the transformer 5 is a step-down transformer. This transformer 5 is also an existing adjustable transformer, used to match different input voltage values ​​and output voltages. This effectively protects circuit components, extends equipment lifespan, and reduces energy consumption, making it suitable for high-voltage areas. Furthermore, the lamp holder 1 contains an MCU control system that controls the drive motor 2 and the light-emitting part 4 via wired or wireless connection. One output terminal of the transformer 5 converts the 90V-300V input voltage to a 2V-12V output voltage to power the MCU control system. The MCU control system includes an MCU, a rectifier module for converting AC to DC for MCU logic control, a filter module using a capacitor-inductor combination filter to eliminate voltage ripple, and a voltage regulator module that outputs a constant low voltage through a linear voltage regulator chip to ensure stable MCU operation.

[0029] In this design, the lamp holder 1 includes a mounting base 12 for fixing to a wall, a hanging rod 13 connected to the bottom of the mounting base 12, and a fixing base 14 connected to the lower end of the hanging rod 13. This split-type lamp holder 1 structure facilitates the installation and disassembly of the fan light, making it suitable for different installation environments. Specifically, the mounting base 12 has a first connector 121 that connects to the upper end of the hanging rod 13, and the fixing base 14 has a second connector 141 that connects to the lower end of the hanging rod 13. The first connector 121 contains a first pin 6 that connects the first connector 121 to the hanging rod 13, and the second connector 141 contains a second pin 7 that connects the second connector 141 to the hanging rod 13. Using pin connections makes the connection between components more stable and reliable, effectively preventing loosening during fan light operation and ensuring normal operation. It also facilitates quick disassembly and replacement of components during maintenance.

[0030] In this solution, the first cavity 11 is disposed in the mounting base 12, and the first cavity 11 is provided with a U-shaped mounting bracket 111 for mounting the transformer 5. The U-shaped mounting bracket 111 is mounted on the first connector 121, and the U-shaped mounting bracket 111 is provided with a fixing plate 112 for fixing the transformer 5 on the U-shaped mounting bracket 111.

[0031] In this design, the drive motor 2 is housed within the fixed base 14, and a connecting plate 8 connects the fan blades 3 to the drive motor 2. Specifically, the connecting plate 8 is annular in shape, with several fan blades 3 evenly distributed on its outer side, and its inner side fixed to the output end of the drive motor 2. The drive motor 2 includes a motor shaft fixed to the fixed base 14 and a rotating disk located at the bottom, with the connecting plate 8 fixed to the rotating disk.

[0032] In this design, the fan blade 3 is provided with a connector 31 for fixing it to the connecting plate 8. The connector 31 includes a fixing part 311 fixed to the connecting plate 8 and a support arm 312 disposed on the fixing part 311 and extending outward for assembling the fan blade 3. Specifically, the fixing part 311 is arc-shaped, with a limiting groove 3111 at one end and a limiting protrusion 3112 at the other end that can cooperate with the limiting groove 3111 on the adjacent fixing part 311. This design not only further improves the stability of the fan blade 3 but also enables quick and accurate positioning during fan blade 3 installation, improving production and installation efficiency.

[0033] In this design, the light-emitting part 4 is connected to the bottom of the fixed base 14. The light-emitting part 4 includes a lamp holder 41 disposed on the fixed base 14, a light strip 42 disposed inside the lamp holder 41, and a lamp cover 43 covering the lamp holder 41. Specifically, the bottom end of the motor shaft extends outward and is fitted with a fixing plate, and the lamp holder 41 is fixed to the fixing plate.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
