DIMMING DEVICE AND ILLUMINATION SYSTEM USING SAME
First Claim
1. A dimming device, comprising:
- a control unit configured to receive a control signal transmitted by a multiplexing transmission method and to control a dimming level of an illumination load in response to the control signal, the illumination load including light-emitting diodes;
a first setting section configured to set a lower limit of the dimming level of the illumination load, the lower limit being adjustable in a first range; and
a second setting section configured to set an upper limit of the dimming level of the illumination load, the upper limit being adjustable in a second range,wherein a minimum value in the second range is greater than a maximum value in the first range.

Abstract
A dimming device includes a control unit, a first setting section and a second setting section. The control unit is configured to receive a control signal transmitted by a multiplexing transmission method and to control a dimming level of an illumination load in response to the control signal. The illumination load includes light-emitting diodes. The first setting section is configured to set a lower limit of the dimming level of the illumination load, the lower limit being adjustable in a first range. The second setting section is configured to set an upper limit of the dimming level of the illumination load, the upper limit being adjustable in a second range. A minimum value in the second range is greater than a maximum value in the first range.

2. An illumination system, comprising:
-
a dimming device electrically connected to a communications line; an illumination load configured to be controlled by the dimming device, the illumination load including light-emitting diodes; and a controller electrically connected to the communications line, the controller being configured to control the dimming device by transmitting a control signal to the dimming device in a multiplexing transmission method, wherein the dimming device includes; a control unit configured to receive the control signal transmitted by the multiplexing transmission method and to control a dimming level of the illumination load in response to the control signal; a first setting section configured to set a lower limit of the dimming level of the illumination load, the lower limit being adjustable in a first range; and a second setting section configured to set an upper limit of the dimming level of the illumination load, the upper limit being adjustable in a second range, wherein a minimum value in the second range is greater than a maximum value in the first range. - View Dependent Claims (3, 4, 5)
