Abstract: A backlight module control circuit of a multi-lamp display device includes a control unit, multiple lamp driving circuits and a fault detection unit. The control unit includes multiple signal output terminals. Input terminals of the lamp driving circuits are respectively coupled to a signal output terminal of the control unit and output terminals of the lamp driving circuits are respectively coupled to a terminal of a lamp. A fault detection unit includes multiple signal detection input terminals, which are respectively coupled to multiple lamp driving circuits and lamps. The fault detection unit can detect whether any one of the lamps is out of order and then output a signal to the control unit, so as to make the control unit shut down the driving circuit of the failure lamp and continue to maintain an operation of other normal lamps.

Abstract: A separate-type cistern handle base mount has a base mount installed onto the side wall of a cistern, a pressure control seat assembled to the front end of the base mount, and a stem inserted through the base mount and fixed at the front end of the pressure control seat. The base mount is a T-shaped anchoring structure and holds a colored decorative piece against the side wall of the cistern tank. The pressure control seat has an end cap fastened to the front end with a center hole to provide for the insertion of the stem through a passage of the base mount, the threaded hole of the sleeve fitting, and the center hole of the end cap. A set screw is fastened into the lateral wall of the end cap to secure the pressure control seat.
