| description | A power-saving lighting system and a method for controlling the same are provided to perform an optimal illuminance in a whole indoor space by controlling brightness of a plurality of lighting units according to ambient light. A sensor type lighting unit(100) comprises a firs light source, an illuminance sensor, an illuminance sensor input part, a main control part, a current control part, and a communication part. The sensor type lighting unit provides an optimal illuminance by controlling brightness of the first light source. The illuminance sensor input part transmits an illuminance value measured by the illuminance sensor to the main control part. The main control part generates a control signal for increasing or decreasing a current provided to the first light source according to the illuminance value received from the illuminance sensor input part. The communication part transmits the illuminance value measured by the illuminance sensor to an adjacent non-sensor type lighting unit. The non-sensor type lighting unit(200) includes a second light source, a communication part, a main control part, and a current control part. The non-sensor type lighting unit provides an optimal illuminance by controlling brightness of the second light source. |
