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.
Claims19
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%.
