Brightness, and further adjust the mixed light color temperature of the light emitting unit 23 . For example: when the current value of the main driving current is high and the current value of the auxiliary driving current is small, the cool white light emitted by the main color temperature light emitting elements 231 is brighter and the partial color light emitted by the secondary color temperature light emitting elements 232 is brighter. The yellow-white light is relatively dark, so that the light-emitting unit 23 mixes cool white light. For another example: when the current value of the main driving current is low and the current value of the secondary driving current is high, the cool white light emitted by the main color temperature luminous elements 231 is relatively dark while the light emitted by the secondary color temperature luminous elements 232 is relatively dark. The yellowish white light is brighter, so that the light emitting unit 23 mixes the yellowish white light.

In this embodiment, since the motor 12 is powered by the DC power supply, compared with the motor 12 powered by AC power, it can run at a lower speed, and has the advantages of saving power and being quieter.

The EMC control unit 35 is electrically connected between the external power source 92 and the power conversion unit 34 and is used to suppress electromagnetic interference, so that this embodiment has better Electromagnetic Compatibility (EMC for short).

During operation, the external power source 92 is firstly converted into the DC power source by the EMC control unit 35 and the power conversion unit 34 and supplies power to the current regulation unit 32 and the microcontroller unit 31 . When the user wants to control the operation of the fan device 1, he can operate the remote controller 91 to send the remote control signal to the wireless transmission unit 33, and the fan drive circuit 312 of the microcontroller unit 31 sends the signal to the motor 12 according to the input signal. The fan driving signal is used to control the rotation of the drive disk 11 . And when the user wants to control the lighting of the lighting device 2, he can also operate the remote controller 91 to send the corresponding remote control signal to the wireless transmission unit 33, and the lighting driving circuit 311 of the microcontroller unit 31 The signal outputs the lighting driving signal to the current regulating unit 32, and the current regulating unit 32 converts the DC power supply into the main driving current and the secondary driving current of the corresponding current value according to the lighting driving signal, thereby adjusting the The luminance of the main color temperature light-emitting element 231 and the secondary color-temperature light-emitting elements 232 enables the light-emitting unit 23 to mix light with different brightness and color temperature.

It should be added that the microcontroller unit 31 can control the main drive current and the secondary drive current output by the current adjustment unit 32 to increase or decrease by a predetermined current value each time the input signal is received through preset settings. . It can be understood that as long as the predetermined current value is lower, the brightness changes of the main color temperature light emitting elements 231 and the secondary color temperature light emitting elements 232 before and after each brightness adjustment are smaller, and when the brightness changes before and after adjustment are small When it is difficult for the user to feel the obvious step difference, the light mixing effect of stepless dimming can be achieved visually.

Through the above description, the advantages of the aforementioned embodiments can be summarized as follows:
