Abstract

A wireless dimming apparatus operatively associated with a driving power apparatus operating with AC power includes a controller, a non-insulting type DC-DC converter for receiving DC power AC-DC converted by the driving power apparatus and converting the DC power into a predetermined operation voltage of the wireless dimming apparatus, a wireless communicator for demodulating an RF signal received through an installed antenna and transmitting the RF signal to the controller, a dimming circuit for receiving a predetermined lighting control signal corresponding to the demodulated RF signal from the controller and transmitting the predetermined lighting control signal to the driving power apparatus, and a DC power switch for supplying the operation voltage to the dimming circuit according to a predetermined control signal of the controller. Accordingly, the wireless dimming apparatus has a small size and high cost efficiency.

Claims

a non-insulating type direct current (DC)-DC converter for receiving DC power AC-DC converted by the driving power apparatus and converting the DC power into a predetermined operation voltage of the wireless dimming apparatus;

a wireless communicator for demodulating a radio frequency (RF) signal received through an installed antenna and transmitting the RF signal to the controller;

a dimming circuit for receiving a predetermined lighting control signal corresponding to the demodulated RF signal from the controller and transmitting the predetermined lighting control signal to the driving power apparatus; and

a DC power switch for supplying the predetermined operation voltage to the dimming circuit according to a predetermined control signal of the controller;

a charging battery for supplying power required for operations of the controller and the wireless communicator in a standby mode,

wherein the DC power is directly supplied to a lighting apparatus,

wherein the DC power switch supplies the predetermined operation voltage to the charging battery in response to the predetermined control signal from the controller.

2. The wireless dimming apparatus according to claim 1, wherein:

the controller monitors a current battery charging state of the charging battery; and

when the current battery charging state is a charging complete state, the controller controls the DC power switch to shut off supply of the predetermined operation voltage to the charging battery.

3. The wireless dimming apparatus according to claim 1, wherein, when the predetermined lighting control signal is a predetermined lighting ON signal for driving the lighting apparatus connected to the driving power apparatus, the DC power is supplied to the non-insulating type DC-DC converter.
