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.

Method for providing direct current to wireless dimmer, and apparatus and system therefor

A lamp control apparatus includes a radio signal control module configured to receive a dimming signal from the outside, to generate a lamp control signal, and to amplify the lamp control signal by a predetermined amount, a driver configured to receive the lamp control signal amplified by the radio signal control module and to control a lamp, and a power supply module configured to supply driving power to the radio signal control module or the driver.

Lamp control apparatus

Disclosed herein is a power supply device for an LED light. The power supply device for an LED light includes a power supply unit for converting input power and providing the converted power to LEDs and a central control unit for controlling an operation of the power supply unit. The power supply unit includes a switching circuit electrically connected to both ends of the LEDs, a switching control circuit configured to control the ON/OFF of the switching circuit, and a dimming control circuit configured to control the amount of power supplied by the power supply unit in response to the ON/OFF of the switching circuit and a dimming control signal received from the central control unit, and the central control unit provides a switching control signal for controlling the switching control circuit in response to the ON/OFF of the LEDs and provides a dimming control signal for controlling the operation of the dimming control circuit.
