Abstract: An integrated circuit for driving high-voltage LED lamps is applied to a rectified alternative current (AC) power and a plurality of LED stacks. The integrated circuit includes a control unit, a plurality of current-clamping units which electrically connect to the control unit and the LED stacks respectively, and a plurality of current-sensing units which electrically connect to the current-clamping units and the control unit. When the rectified power is switched on, the current-sensing unit constantly monitors the electrical current flowing through the respective current-clamping unit and feeds back the monitored data to the control unit. The control unit sequentially switches on or off the current-clamping units according to the combinatorial logic state of the monitored data.

Abstract: A buckle includes a first fastener and a second fastener. The second fastener has two hooks. The first fastener includes a socket, a locking piece disposed in the socket, and two first locking portions formed on the socket for mating with the hooks. The locking piece is slidingly connected in the socket to cooperate with the second fastener. When the first fastener is engaged with the second fastener, the locking piece enters the second fastener to restrict the movement of the second fastener, so that the second fastener cannot be released unless the locking piece is removed from the second fastener and the hooks of the second fastener are pressed. Thus, the second fastener can be released only when the locking piece is moved, thereby preventing a problem that the second fastener may be separated from the first fastener when the hooks of the second fastener are incautiously pressed. A user has to move the locking piece with one hand and presses the hooks with another hand.
