To solve a problem, found in a case where a light-emitting diode emitting the light within an area of visible light is used as inside lighting of a refrigerator and the like, wherein it is necessary to increase electric current by the amount used by the light-emitting diode with respect to a light source device of the refrigerator, which causes the increase in dimension and cost increase of the power source device.
When a lighting device 20 is put on, a fan 10 for cooling the refrigerator using a DC power source is stopped, thus the electric current used in the light-emitting diode 2 can be covered by the reduction of electric current in stopping a load device. As the increase of current capacity of the power source device is prevented, the refrigerator can be minimized and the cost can be reduced.
