To generate light emitting patterns almost the same as those of electric bulbs using an LED light source concerning a light source lighting device for game machines.

A data ROM 220 of a lighting control part 200 has data previously stored for indicating lighting patterns of a light source comprising a series circuit in which a red LED (R), a green LED (G) and a blue LED (B) are connected in series and the data are supplied respectively to drivers 230, 240, etc.,... as lighting data signals P10, P11, P12, P13, P14, etc., and lighting date signals P20, P21, P22, etc. The drivers 23 and 240 dynamically drive an LED array 260 according to the lighting data signals P10, P11, P12, P13 and P14 and the lighting data signal 20 to obtain white light from each LED series light source within the LED array. Likewise, LED arrays 270 and 280 generate white light.
