Abstract: The present invention discloses a power converter contained base, lamp with power converter contained base and lamp with separable power converter contained base. The power converter contained base comprises a first commercial standard base, fundament, cover, power converter and a first connector. The fundament comprises a first opening connected to the commercial standard base and a second opening where the cover disposed. A containing space may be defined by the cover, base and the first commercial standard base. The power converter may be disposed inside the containing space. The first connector may be disposed on the cover or the fundament to be connected with a second connector of a light-emitting member to make the four elements, the first commercial standard base, the power converter, the one of or the combination of two or three of, the fundament, the cover and the connector, and the light-emitting member become electrically connected.

Abstract: The present invention is directed to a lighting master, which includes a base and a lighting module. A region defined between the base and a housing accommodates a power module. The lighting module is disposed over the base. The base has an outer surface to be bonded with an inner surface of the housing.

Abstract: A power-saving lighting apparatus including an upper housing, a bottom cover assembled with the upper housing, a lighting module and a positioning member is provided. The lighting module is disposed between the upper housing and the bottom cover, and the lighting module is mechanically supported by the bottom cover. The positioning member is disposed on the lighting module, wherein a relative position of the lighting module and the bottom cover is maintained by the positioning member.

Abstract: Processes for producing porous carbon foam composites and activated carbon/carbon (AC/C) composites from polyimide precursors, activated carbon powder, and optionally carbon fiber and other additives. The AC/C composites may be used for carbon electrodes in electrochemical capacitors.

Abstract: Disclosed are processes for producing monolithic and metal doped monolithic porous carbon disks from prepolymer organic precursors in the powder form composed of either or both polyimide and polybenzimidazole. The powders are consolidated (compressed) into disks and then pyrolyzed to form the desired porous carbon disk. Porous carbon-carbon composite disks are also prepared by adding carbon to the prepolymer organic precursors.
