Title:
INTEGRATED LED LIGHTING CONTROL SYSTEM HAVING DEFECT DIAGNOSIS AND HANDLING FUNCTION
Document Type and Number:
WIPO Patent Application WO/2017/094944
Kind Code:
A1
Abstract:
The present invention provides an integrated LED lighting control system having a defect diagnosis and handling function, comprising: a switched mode power supply (SMPS) (400) unit converting inputted alternating current power into direct current power by using a rectifier circuit, so as to supply the direct current power to an LED lighting lamp (500), and having two or more SMPSs connected in parallel; the LED lighting lamp (500) electrically connected to the SMPS (400) unit, emitting light to the outside by using the direct current power as a power source, and capable of adjusting the amount of emitted light; a sensor unit (600) including a movement detecting sensor (610) for detecting the presence or the movement of a human or an object, a power detecting sensor (620) for detecting the amount of inputted power, and an illuminance sensor (630) provided at one side of the LED lighting lamp (500) so as to measure the illuminance emitted from the LED lighting lamp (500); an integrated controller (IC) unit (300) for controlling the SMPS (400) and the illuminance of the LED lighting lamp according to a dimming command; an integrated control program (ICP) unit (100) for controlling the illuminance of the LED lighting lamp (500) through a dimming control, and controlling the SMPS (400) unit such that power is conducted by the normally operable SMPS (400) in the SMPS (400) unit, according to a data value sensed and inputted by the sensor unit (600); and a mid controller (MC) unit (200) allowing the ICP unit (100) to transmit a control command to the IC unit (300) and allowing the IC unit (300) to transmit and receive, in a wired or wireless manner, a data value measured through the sensor unit (600).
