Abstract

A lighting system with reduced standby power according to the embodiment includes a main control unit to control a lighting device; a driver to supply the control signal to the lighting device; and an AC-DC converting circuit to supply power to the driver. A method of reducing standby power according to the embodiment includes charging a standby power supply unit with power in a normal mode; checking whether a lighting off signal is transmitted and switching off a lighting, and simultaneously, shutting off the power supplied from the AC-DC converting circuit when the lighting off signal is transmitted; changing an operation mode of a lighting device from a normal mode to a standby mode; checking whether a voltage of the standby power supply unit is less than a predetermined level; and charging the standby power supply unit when the voltage is less than the predetermined level.

Description

technical field [0001] Embodiments relate to a lighting system with reduced standby power. More particularly, embodiments relate to a standby power cut-off system using wireless communication. Background technique [0002] Standby power refers to power consumed just after a power source is switched off, that is, power consumed irrespective of the operation of an electric appliance. [0003] In general, lighting devices employ dimmers to properly maintain the intensity of lighting according to indoor environments and reduce unnecessary power consumption. The dimmer is connected to the lighting device to control the on / off operation, lighting level, and color temperature level of the lighting device. [0004] Recently, with the development of wireless communication technology, a technology for collectively controlling lighting devices using wireless dimmers from a distance has been suggested. In such a case, the control unit of the wireless dimmer must always be kept in nor...
