PURPOSE:To easily and alternately emit monochromatic light LED, by connecting monochromatic light emitting diodes LED between lead-out wires in mutually parallel and inverse polarity and alternately changing the polarity of drive voltage. CONSTITUTION:Two lead-out wires 21, 22 are provided to a case 1 and one lead-out wire 21 is connected to a terminal 5 by soldering and a terminal 6 is connected to the other lead-out wire 22 by soldering. When positive voltage is applied to the terminal 5 and negative voltage to the terminal 6 by a drive circuit, a monochromatic light LED 3 emits light. Therefore, by alternately reversing the polarity of the voltage applied between the terminals 5, 6, LEDs 3, 4 can alternately emit light. |
