ABSTRACT:
A clothes washing machine includes a body, a tub within the body, a cover for the body, and an illumination device for illuminating an interior of the body. The illumination device includes a downwardly depending socket having a lamp mounted therein; and a case encompassing the lamp and forming a water-tight seal with the socket. Light is emitted from a lower end of the case, which is covered by a light-concentrating lens. The lamp is energized by a secondary coil of a transformer and is turned on and off by a switch. The lamp is turned on when the cover is open. Another secondary coil of the transformer supplies power to a microcomputer which operates the switch.
