<p>PURPOSE:To perform a wide range and easy-to-set dimmer control by providing the connecting parts of floodlights having a dimmer circuit and a flashing circuit, respectively, on a dimmer device, and setting and controlling the upper and lower limits of the dimmer range by a specified operation. CONSTITUTION:When a continuous operation is conducted in the range of 0-100% by a dimmer 1, a control signal is outputted to a floodlight 3 having a dimmer circuit through a dimmer signal line 5 and dimming is conducted. When the signal value exceeds the upper limit value 100% of the light 3, a floodlight 2-1 having a flashing circuit is lighted, and the light 3 is extinguished. Further, the extinguished light 3 is brought under dimmer control by the device 1, and when the signal value exceeds the upper limit value 100%, a floodlight 2-2 having a flashing circuit is lighted, and the light 3 is extinguished. The light 3 dimmer is again made under control, and the range of the control can be extended. When the signal of the device 1 conversely becomes lower than the lower limit value 0% of the light 3, the lights 2-2, 2-1 are successively extinguished, and only the light 3 is finally lighted.</p> |
