Ceiling-fan lamp with multiple control modes

A ceiling-fan lamp with multiple control modes, comprising:

• a housing, a ceiling-fan motor, a lamp, ceiling-fan blades, a pull wire and a control circuit board;
• the ceiling-fan motor, the lamp and the control circuit board all installed in an accommodating cavity of the housing, and the ceiling-fan blades and the pull wire each extending to an exterior of the housing;
• the control circuit board being electrically connected to a DC power supply with voltage less than or equal to 48V, and the control circuit board including a control-and-management module, an action control module, a communication module, a motor drive module and a lamp driver module;
• the action control module and the communication module being electrically connected to the control-and-management module respectively, the action control module configured to receive action signals generated by the pull wire, the action signals being digital signals, and the communication module configured to receive communication signals;
• the motor drive module being electrically connected to the ceiling-fan motor;
• the lamp driver module being electrically connected to the lamp;
• the control-and-management module configured to receive and process the action signals or the communication signals, and then providing first control signals and second control signals respectively to the motor drive module and the lamp driver module, and the motor drive module configured to drive the ceiling-fan motor to work or stop working according to the first control signals, so as to control the rotation or stopping of the ceiling-fan blades;
• the lamp driver module configured to control the lamp to glow or go out according to the second control signals;
• wherein the control-and-management module is to process a latest received signal out of the two of the action signals and the communication signals, and after processing the latest received signal, the control-and-management module issues corresponding control commands to the motor drive module and the lamp drive module;
• the control-and-management module including a control-and-management chip;
• the communication module being a Wi-Fi module which includes a Wi-Fi chip, resistors and capacitors;
• the Wi-Fi module including an optocoupler-detection reserved hole for detecting abnormality in the Wi-Fi module;
• a transmission data (TXD2) terminal of the Wi-Fi chip being a serial port communication terminal, and the TXD2 terminal electrically connected to a SPEED_TXD terminal of the control-and-management chip;
• a second receiving data (RXD2) terminal of the Wi-Fi chip being a serial port communication terminal, and the RXD2 terminal electrically connected to a receiving data (RXD) signal terminal of the control-and-management chip;
• wherein the Wi-Fi module receives the communication signals, and provides the communication signals via the RXD2 terminal and the TXD2 terminal of the Wi-Fi chip each to the RXD signal terminal and the SPEED_TXD terminal of the control-and-management chip.
