[0043] In a specific embodiment, the signal receiving sub-circuit 113 may be an infrared receiving circuit, which is configured to receive a control signal sent by the user through an infrared remote control or another apparatus. The micro-control sub-circuit 114 may be a radio frequency circuit, and specifically may be a Bluetooth circuit, a Wi-Fi circuit, a ZigBee circuit, or the like. In practical applications, when receiving the control signal sent by the user, the signal receiving sub-circuit 113 sends startup information to the micro-control sub-circuit 114.

The other end of the ninth resistor R.sub.9 and the second end of the signal receiver U.sub.1 are connected to the micro-control sub-circuit 114 through an IR interface.

[0048] In this embodiment, the signal receiver U.sub.1 is an integrated infrared receiving and decoding chip. When an infrared signal emitted by a remote control irradiates a surface of the signal receiver U.sub.1, a third end, namely an OUT pin, outputs an infrared coded signal, the signal is sent to the micro-control sub-circuit 114 for processing, and then action of the lighting apparatus is controlled.

[0049] In this embodiment, the control circuit 11 is disposed on the lamp panel 102, so that signal receiving antennas of both the signal receiving sub-circuit 113 and the micro-control sub-circuit 114 do not need to be exposed, which facilitates mounting and is more beautiful.

[0051] In this embodiment, a fifth end of the LED drive chip U.sub.2 is grounded. The first resistor R.sub.1 is connected to the micro-control sub-circuit 114 through an SDA interface, and the second resistor R.sub.2 is connected to the micro-control sub-circuit 114 through an SCL interface.

[0052] In this embodiment, the fourth end of the LED drive chip U.sub.2 is an output end, and includes a plurality of OUT output interfaces, and the LED lamps form a plurality of LED lamp groups. The LED lamps 106 in each LED lamp group may be connected in series, in parallel or in series and parallel. Each OUT output interface of the LED drive chip U.sub.2 is connected to a cathode of the LED lamp group.

[0053] In this embodiment, the plurality of LED lamp groups may have different colors and different brightness. Through control over the plurality of LED lamp groups, a light color, light brightness, cold light, warm light, and the like of the lighting apparatus can be adjusted.

[0055] In a specific embodiment, as shown in FIG. 8a and FIG. 8b, a target speed-regulating unit of the at least two speed-regulating units includes a fourth resistor R.sub.4, a fifth resistor R.sub.5, a first diode D.sub.1, a first triode Q.sub.1, a first relay RE1, and a first capacitor C11, where the first relay RE1 includes a first inductance coil and a first switch SW1, one end of the fourth resistor R.sub.4 is connected to one end of the fifth resistor R.sub.5 and the micro-control sub-circuit 114, the other end of the fourth resistor R.sub.4 is connected to a base of the first triode Q.sub.1, the other end of the fifth resistor R.sub.5 is grounded, a collector of the first triode Q.sub.1 is connected to an anode of the first diode D.sub.1 and one end of the first inductance coil, an emitter of the first triode Q.sub.1 is grounded, a cathode of the first diode D.sub.1 is connected to the other end of the first inductance coil, one end of the first switch SW1 is connected to the load motor, the other end of the first switch SW1 is connected to one end of the first capacitor C.sub.11, and the other end of the first capacitor C.sub.11 is connected to the power supply; the target speed-regulating unit is any one of the at least two speed-regulating units, and capacitance values of first capacitors C.sub.11 in different speed-regulating units are different.

[0056] In this embodiment, the fourth resistor R.sub.4 and the fifth resistor R.sub.5 are connected to the micro-control sub-circuit 114 through an L1 interface.

[0057] In this embodiment, one of the at least two speed-regulating units may not be provided with a capacitor, which is used to distinguish from the speed-regulating unit provided with the first capacitor C.sub.11. Specifically, as shown in FIG. 8b, a switch SW2 is connected to a capacitor C.sub.12 having a different capacitance value from the first capacitor C.sub.11, and a switch SW3 is connected to no capacitor. In practical applications, a capacitor is used in an alternating current circuit to reduce voltage. A smaller capacitance indicates a larger capacitive reactance, a larger voltage drop, and a relatively low motor speed; and a larger capacitance indicates a smaller capacitive reactance, a smaller voltage drop, and a relatively high motor speed. In this embodiment, because of different capacitance values of capacitors connected to three switches in parallel, the load motor speed is different when different switches are turned on.

Specifically, FIG. 12 is a schematic circuit diagram of the power module. The power module includes a chip U.sub.9, an input end of the chip U.sub.9 is connected to the micro-control sub-circuit 114, and an output end of the chip U.sub.9 is connected to the DC motor. A model of the chip U.sub.9 is SD05M50DAED.

[0064] The lighting apparatus according to the present application is provided with the LED drive sub-circuit 112 and the motor drive sub-circuit 111, and can not only implement lighting, but also control a fan. In addition, the LED drive sub-circuit 112 is connected to a plurality of LED lamp groups, and can adjust a light color, light brightness, cold light, warm light, and the like of the lighting apparatus through control over the plurality of LED lamp groups. Furthermore, the motor drive sub-circuit 111 includes at least two speed-regulating units and one motor steering unit, which are configured to control a speed and steering of a fan motor. The lighting apparatus according to the present application enables the user to adjust the light and the fan based on the user's own requirements and has various functions.
