回路を形成したことを特徴とする照明器具。 A rotating lamp section with a pair of lamps arranged on both sides of the socket section, a device main body that pivotally supports the socket section of the rotating lamp section and holds the rotating lamp section rotatably within a vertical plane, and both lamps. A rotation detection switch includes a limit switch that is driven at a main part of the rotating lamp section when the rotating lamp section is rotated from a predetermined position arranged in the vertical direction, and the lighting state of each lamp is output from the rotation detection switch. When the rotation detection signal output from the rotation detection switch is obtained, one lamp is gradually dimmed at a predetermined time constant, and the other lamp is dimmed at a predetermined time constant. A lighting control circuit is formed by an interlocking dimming circuit that gradually increases the brightness with a constant constant, and an inversion control circuit that reverses the dimming and brightening control for each lamp every time a rotation detection signal is obtained. lighting equipment.
