Abstract

A lighting apparatus includes a main controller, a fan driver module and a light driver module. The lighting apparatus is coupled to a wall switch. The wall switch is operated by a user to selectively send a wireless fan command a wireless light command to the main controller. The main controller translates the fan command to a fan control signal to the fan driver module. The fan driver module generates a fan driving current to a fan device. The main controller translates the light command to a light control signal to the light driver module. The light driver module generates a light driving current to a light source.

Claims (22)

1 . A lighting apparatus coupled to a wall switch, comprising:

a main controller, wherein the wall switch is operated by a user to selectively send a wireless fan command or a wireless light command to the main controller;

a fan driver module, wherein the main controller translates the fan command to a fan control signal to the fan driver module, wherein the fan driver module generates a fan driving current to a fan device;

a light driver module, wherein the main controller translates the light command to a light control signal to the light driver module, wherein the light driver module generates a light driving current to a light source, wherein the main controller has a PWM circuit for splitting a first duty ratio of a first output power to the fan device and a second duty ratio of a second output power to the light source, wherein a sum of the first duty rain and the second duty ratio is 100%.

2 . The lighting apparatus of claim 1 , further comprising a AC-DC converter, wherein the AC-DC converter supplies power to the main controller, the fan driver module and the light driver module.

3 . The lighting apparatus of claim 2 , wherein the light source comprises multiple LED modules, wherein the light control signal comprises a ratio between sub-currents respectively supplied to the multiple LED modules, wherein the multiple LED modules have different parameters.

4 . The lighting apparatus of claim 2 , wherein the fan driver module comprises a DC-DC converter, wherein the DC-DC converter is coupled to the AC-DC converter to generate the fan driving current.

5 . The lighting apparatus of claim 1 , wherein a temperature sensor detects an operation temperature of the light source, wherein the main controller adjusts the fan control signal based on the operation temperature.

6 . The lighting apparatus of claim 1 , wherein the wall switch has a panel disposed a fan switch and a light switch respectively for generating the fan command the light command.

7 . The lighting apparatus of claim 6 , wherein the main controller is further connected to a secondary wall switch with a wire, wherein a series of on-off operation on the secondary wall switch is encoded as the light command the fan command to the main controller.

8 . The lighting apparatus of claim 1 , wherein the main controller generates an indication signal to the light control module for the light source to generate a visual signal corresponding to the fan device.

9 . The lighting apparatus of claim 8 , wherein when the fan control module detects an abnormal status of the fan device, the fan control module instructs the main controller to generate the indication signal.

10 . The lighting apparatus of claim 1 , wherein the fan device is configured to form an air flow tunnel.

11 . The lighting apparatus of claim 10 , wherein a ultraviolet light source is disposed in the air flow tunnel to disinfect air in the air flow tunnel.

12 . The lighting apparatus of claim 10 , wherein a heater is disposed in the air flow tunnel to heat the air.

13 . The lighting apparatus of claim 1 , wherein a remote control sends a second fan command a second light command to the main controller.

14 . The lighting apparatus of claim 13 , wherein the remote control and the wall switch use different wireless protocols.

15 . The lighting apparatus of claim 1 , wherein the wall switch has a rotation base for rotating a transmitter to align with the direction of the main controller.

16 . The lighting apparatus of claim 1 , wherein the wall switch is attached on a traditional wall switch, wherein the wall switch gets power from the traditional wall switch.

17 . The lighting apparatus of claim 16 , wherein the traditional wall switch is connected to the main controller with a wire.

18 . The lighting apparatus of claim 17 , wherein the traditional wall switch only controls the light source.

19 . The lighting apparatus of claim 1 , wherein the light command the fan command is encoded with an identifier after the wall switch is matched with main controller.
