Abstract:
Disclosed are a light emitting diode (LED) module and a lighting assembly. The lighting assembly comprises a light emitting device, a driver integrated circuit device for driving the light emitting device, a heat sink for dissipating heat generated from the light emitting device, and a heat shielding portion for blocking thermal interference between the driver integrated circuit device and the light emitting device. In the LED module, the driver integrated circuit device is disposed on the heat shielding portion. Accordingly, it is possible to block thermal interference between the light emitting device and the driver integrated circuit device and to decrease the size of the lighting assembly.
Abstract:
An electrical power substrate comprises a metallic body at least one surface of the body having a coating generated by plasma electrolytic oxidation (PEO). The coating includes a dense hard layer adjacent the said surface of the metallic body, and a porous outer layer. Electrically conductive elements are attached to the said coating.
Abstract:
An RF interconnect is incorporated in RF module packages (50) for direct attachment onto a multi-layer PWB (100) using compressible center conductor (fuzz button) interconnects. The module has circuitry operating at microwave frequencies. The module package includes a metal housing (52) including a metal bottom wall structure (54). The module includes a plurality of RF interconnects, which provide RF interconnection between the package (50) and the PWB (100). Each interconnect includes a feedthrough center pin (72) protruding through an opening formed in the metal bottom wall, with isolation provided by a dielectric feedthrough insulator (74). The center pin is surrounded with a ring of shield pins (76) attached to the external surface of the bottom wall of the module housing. The pins are insertable in holes (116a, 116b) formed in the PWB (100), and make contact with fuzz button interconnects (130, 132) disposed in the holes (116a, 116b). Circuitry (148, 150) connects the fuzz button interconnects (130, 132) to appropriate levels (120, 122, 124) of the PWB signal conduction.
