CONSTITUTION: A lighting device includes a first lamp, a second lamp(110), a dimming setting part(130), and a control module(120). The first lamp and the second lamp are operated by an AC power. The dimming setting part selects illuminance of the first lamp and the second lamp. The control module includes an SMPS(Switching Mode Power Supply)(121), a control part(127), and a lamp driving part(125). The SMPS rectifies the AC power into a DC power. The control part generates a dimming setting signal for controlling the first lamp and the second lamp according to a resistance value of the dimming setting part. The lamp driving part drives the first lamp and the second lamp according to the dimming setting signal.</p> |
