Abstract: A lighting apparatus includes a fan, a light device, an integrated housing, a main controller, a fan controller, a light controller and a converter. The integrated housing is used for disposing the fan and the light device. The converter converts an external AC power to a direct current. The fan controller is coupled to the converter for generating a fan driving current to the fan according to a fan control signal from the main controller. The light controller is coupled to the converter for generating a light driving current to the light device according to a light control signal. The main controller receives a wireless main control signal from a wall switch operated by a user. The main controller generates the fan control signal and the light control signal based on the wireless main control signal.

Abstract: The disclosure relates to a table (100). The table (100) has a table top (102), a plurality of legs (104) connectable to the table top (102), and an air purifier (106) adapted to be placed below the table top (102). A bottom side of the table top (102) is provided with at least one groove (112) extending in a circumferential direction for preventing liquid from traveling from an outer edge of the table top (102) along the bottom side of the table top (102) and reaching an inner section of the air purifier (106). The disclosure also relates to a method for purifying air using a table (100).
