A method for manufacturing flip-chip light emitting diode (LED) package. A recess array is formed at the top surface of a silicon wafer. Two through-wafer via holes are formed in the recess. A plurality of LED chips are flip-chip mounted in each of the recesses, respectively. Two electrodes of each LED chip are respectively covered the two via holes. An encapsulator for encapsulating each LED chip is arranged in the recess to provide a flat top surface. A metal layer is deposited on the bottom surface of the silicon wafer to electrically connecting with the electrodes through the two via holes. Metal lines which electrically connecting the electrodes are formed by patterning the metal layer. A plurality of silicon submounts, each including at least one recess, are cut off from the silicon wafer. A fluorescent layer is arranged on the top surface of the encapsulator.

A temperature switch includes a housing, a switching unit installed in the housing and including a resilient movable conductive plate that is movable between on and off positions, and a temperature control unit mounted on the housing and including a heat-conductive cover that is adapted to conduct heat of a heating element, a temperature-responsive element abutting against the cover, and a control rod and a fuse element disposed between the temperature-responsive element and the movable conductive plate to be moved by the temperature-responsive element so as to contact the movable conductive plate. The control rod has two opposite ends respectively extending towards the temperature-responsive element and the movable conductive plate. The fuse element is disposed at one of the ends. When the fuse element is melted, the control rod is disconnected from the temperature-responsive element either structurally or functionally.

A resonant conversion control device with a very low standby power consumption has an AC-to-DC conversion unit, a DC-to-DC conversion unit, a DC-to-DC conversion control unit, and a standby mode control unit. The resonant conversion control device effectively makes use of the low switching loss characteristic of a resonant conversion device, and uses the output voltage for judgement of the system operation mode. The resonant conversion control device can control the action statuses of the AC-to-DC conversion unit and the DC-to-DC conversion unit to lower effectively the power consumption under the standby mode. Therefore, the resonant conversion control device can solve the problem of a higher standby power consumption of conventional switching power supplies and meet the requirements of future standby power standards.
