POWER CONTROL DEVICE FOR LED LIGHTING AND LIGHTING SYSTEM
First Claim
1. A power control device capable of controlling illuminance of a lighting fixture by outputting current that drives the lighting fixture and controlling the current, comprising:
- a first circuit section including a receiver for receiving a wireless signal having a predetermined frequency, a control signal generating circuit for generating a control signal according to the number of times of reception of the wireless signal at the receiver, and a first alternating current-direct current conversion circuit for converting alternating-current voltage into direct-current voltage; and
a second circuit section for generating and outputting current according to the control signal from the first circuit section, the second circuit section including a second alternating current-direct current conversion circuit for converting alternating-current voltage into direct-current voltage,wherein the first alternating current-direct current conversion circuit is in a state of being operated at all times, and the second alternating current-direct current conversion circuit is operated when outputting driving current for the lighting fixture according to the control signal from the control signal generating circuit and is not operated when not outputting driving current.
