<p>PROBLEM TO BE SOLVED: To provide an illuminator for game machine capable of various kinds of illuminations by displaying the change of a color or tone while using a full color light emitting diode (LFD) for a light source. SOLUTION: Three resistors R1-R3, R4-R6 and R7-R9 with respective different resistance values are parallel connected to red LED 3a, green LED 3b and blue LED 3c of full color LED 3, the arbitrary combination of these resistors R1-R9 is selected, ON/OFF is controlled by a driver 14, emission in any arbitrary color is enabled and the tone or lightness can be changed.</p> |
