摘要： A heat dissipation device is provided for dissipating heat generated by electronic components mounted on a printed circuit board in an electronic system. The electronic components have different heights. The heat dissipation device includes a connecting plate, at least two elastic members mounted on the connecting plate, and a heat sink having a substrate mounted on the connecting plate and located above one of the electronic components. A number of joining members extend through the printed circuit board and engage with the substrate to attach the substrate on the one electronic component on the printed circuit board. A distance between the substrate and the connecting plate is adjustable by adjusting the joining members to make the substrate intimately contact the one electronic component.

摘要： The present invention provides a control circuit for LED driver. A voltage-feedback circuit is coupled to LEDs to sense a voltage-feedback signal for generating a voltage loop signal. Current sources are coupled to the LEDs to control LED currents. A detection circuit is connected to sense voltages of current sources for generating a current-source loop signal in response to a minimum voltage of the current sources. Furthermore, a buffer circuit generates a feedback signal in accordance with the voltage loop signal and the current-source loop signal. The feedback signal is coupled to limit a maximum voltage of the LEDs and regulate the minimum voltage across the current sources.

摘要： A heat dissipation device includes a base (10), a plurality of fins (20), first and second heat pipes (30), (40), a fan holder (50) and a fan (60) secured to the fan holder. The first heat pipe includes a heat-receiving section (32) and two heat-discharging sections (34). The second heat pipe includes an evaporating portion (42) and two condensing portions (44). The condensing portions of the second heat pipe extend into the fins and are disposed adjacent to opposite ends of each of the fins. One heat-discharging section extends in the fins and is disposed between the condensing portions, thus allowing heat absorbed from the base to be evenly distributed throughout the fins by the heat-discharging sections and the condensing portions.
