LIGHTING SYSTEM AND CONTROL CIRCUIT FOR THE SAME

摘要

Disclosed herein are a lighting system for emitting light using power having a phase controlled by a dimmer and improving the light emission state of a light source and a control circuit for the same. Shimmer can be improved by performing charging and discharging using a current supplied to a load or a current flowing in the current path of a load and performing current control using a charging voltage generated by the charging and discharging.

主权项

1. A lighting system, comprising:
a light source supplied with a rectified voltage obtained by controlling a phase of AC power using a dimmer; a power control unit configured to provide a current path for light emission of the light source in accordance with a state of the rectified voltage; and a current controller configured to perform charging or discharging in response to an amount of current on the current path that is changed by characteristics of the dimmer and to control an amount of current for the light emission of the light source which flows in the current path in accordance with the charging or discharging.
