Title:
GALVANOSTATIC LIGHTING CONTROL SYSTEM CAPABLE OF CUTTING OFF STANDBY POWER, AND DALI BALLAST
Document Type and Number:
WIPO Patent Application WO/2023/182850
Kind Code:
A1
Abstract:
The present invention relates to a lighting control system comprising: a building management server for transmitting a control signal for a device to be controlled in a building; a control panel for transmitting, in response to the reception of the control signal from the building management server, a digital addressable lighting interface (DALI) protocol signal for controlling the lighting to a DALI ballast through a DALI communication line; the DALI ballast which is electrically connected to one or more light-emitting diode (LED) lightings, and which supplies, in response to the reception of the DALI protocol signal from the control panel, power to an LED lighting corresponding to the received DALI protocol signal from among the one or more LED lightings; and the one or more LED lightings for receiving power from the DALI ballast and emitting light, wherein the DALI ballast includes: a converter, which receives power of a first voltage level from a power source so as to convert same into power of a second voltage level for emitting light; and a control circuit for control the on/off of the supply of the power source input into the converter between the converter and an input line by which the power of the first voltage level is received from the power source, and the control circuit is controlled to be on/off on the basis of the DALI protocol signal received from the control panel.
